The Electrodialysis with Filtration Membrane (EDFM) system has shown promise in juice enrichment, but further optimization is needed. This study evaluated the effect of processing duration (3 and 6 h) on juice composition, process efficiency, and membrane fouling. Results demonstrated a significant impact of processing time on juice composition, especially anthocyanin and mineral content. Two anthocyanin-depleted juices (−18.94% and −30.70%) and two anthocyanin-enriched juices (26.21% and 44.21%) were produced. Similar energy (1512.13 Wh/g of anthocyanins) was required to migrate equivalent amounts of anthocyanins over both time periods, with no impediment due to fouling observed, although the system's resistance increased (2.5-fold after 3 h, 3.2-fold after 6 h). Membrane fouling was characterized through conductivity, thickness, ATR-FTIR, SEM-EDX, and foulant identification. Minimal anthocyanin accumulation occurred on cation-exchange membranes (CEM), while anthocyanins and PACs concentrated within the filtering layer of filtration membranes (FM). However, fouling did not increase with longer processing. Structural alterations were noted in anion-exchange membranes (AEMs), suggesting instability under high electric fields. Overall, EDFM effectively enriched cranberry juice with anthocyanins, but further research is necessary to address AEM degradation under limiting current density conditions. [ABSTRACT FROM AUTHOR]

This study investigated the potential of Cranberry extract to stimulate osteogenesis in vitro. The total phenolic and monomeric anthocyanin contents in the Cranberry were determined. Liquid chromatography coupled with mass spectrometry was used to identify the Cranberry's constituents. To assess the Cranberry's cytotoxicity, a thiazolyl blue tetrazolium bromide assay was employed. Concerning the osteogenesis potential of Cranberry, alkaline phosphatase (ALP) activity, bone morphogenetic protein 2 (BMP-2) expression, and extracellular matrix mineralization were evaluated. The total phenolic content was 522.72 ± 9.80 mg GAE g-1 ES and 364.95 ± 12.49 mg GAE/g detected by the Fast Blue BB and Folin–Ciocalteu method, respectively. For monomeric anthocyanin, the content was 460 ± 30 mg ECG g-1 ES. Moreover, Cranberry concentrations ranged from 62.5 to 500 mg/mL and were found to be biocompatible with osteoblasts and mesenchymal stromal cells. Regarding osteogenesis, 20 mg/mL of Cranberry promoted 2-fold more ALP activity and almost 1.5-fold more BMP-2 than compared to the positive control group. Additionally, 200 mg/mL of Cranberry stimulated a 1.7-fold increase in extracellular matrix mineralization compared to the positive control group. In conclusion, Cranberry displayed potential in stimulating early and late markers of osteogenesis. Its ability to promote osteogenesis and its biocompatibility at higher concentrations hold promise for future application into biomaterials for bone regeneration. [ABSTRACT FROM AUTHOR]

Modern trend in the food industry is the development of technology for healthy food products with increased nutritional value and enriched with new types of vegetable raw materials. Oatmeal cookies are popular among different groups of people. The purpose of the study is to develop a technology for producing oatmeal cookies by replacing premium wheat flour with spelled flour, and raisins with dried cranberries and Japanese persimmons. The choice of enrichment agents is justified. The recipe for the "Oatmeal New" cookie was taken as a control sample. We replaced premium wheat flour with spelled flour in a ratio of 70 : 30; 50 : 50; 30 : 70; 0 : 100. Persimmon has replaced 30 % of white sugar. The sample with full replacement of wheat flour with spelled flour is recognized as the best. A recipe for "Sweet Morning" oatmeal cookies has been developed. Organoleptic and physicochemical quality indicators of oatmeal cookies have been determined. The antioxidant activity of cookies of the new composition is 0.28 mg of quercetin/100 g of product, which is higher than in the control sample by 0.05 mg of quercetin/100 g of product. The nutritional and energy value of the products has been calculated. Oatmeal cookies "Sweet Morning" exceed the control sample in protein content by 1.2 times, dietary fiber by 2 times, vitamin В1 – 1,2, В5 – 2,3, В9 – 1.24, vitamin C – 5.8, PP – 1.3, K – 6.3, β-carotene – 1.5; minerals K – 1.9, Ca – 1.6, Mg – 1.8, P – 1.8; and microelements: Fe – 1.4, Zn – 2.5, Cu – 2.7, Se – 1.5, Mn – by 2.5 times. The energy value of the new product is 40 kcal (167 kJ) lower compared to the control one. "Sweet Morning" oatmeal cookies is recommended for people focused on maintaining a healthy lifestyle and a balanced diet.

Objectives: This study examined the effect of a 4-week unsweetened cranberry beverage (CRAN) (317 mg polyphenols) versus placebo beverage (PLAC) ingestion (240 mL/day) on moderating exercise-induced changes in innate immunity. Methods: Participants included 25 male and female non-elite cyclists. A randomized, placebo-controlled, double-blind crossover design was used with two 4-week supplementation periods and a 2-week washout period. Supplementation periods were followed by an intensive 2.25 h cycling bout. Six blood samples were collected before and after supplementation (in an overnight fasted state) and at 0 h, 1.5 h, 3 h, and 24 h post-exercise. Stool and urine samples were collected pre- and post-supplementation. Outcome measures included serum creatine kinase, myoglobin, and cortisol, complete blood counts, plasma untargeted proteomics, plasma-targeted oxylipins, untargeted urine metabolomics, and stool microbiome composition via whole genome shotgun (WGS) sequencing. Results: Urine CRAN-linked metabolites increased significantly after supplementation, but no trial differences in alpha or beta microbiota diversity were found in the stool samples. The 2.25 h cycling bout caused significant increases in plasma arachidonic acid (ARA) and 53 oxylipins (FDR q-value < 0.05). The patterns of increase for ARA, four oxylipins generated from ARA-cytochrome P-450 (CYP) (5,6-, 8,9-, 11,12-, and 14,15-diHETrEs), two oxylipins from linoleic acid (LA) and CYP (9,10-DiHOME, 12,13-DiHOME), and two oxylipins generated from LA and lipoxygenase (LOX) (9-HODE, 13-HODE) were slightly but significantly higher for the CRAN versus PLAC trial (all interaction effects, p < 0.05). The untargeted proteomics analysis showed that two protein clusters differed significantly between the CRAN and PLAC trials, with CRAN-related elevations in proteins related to innate immune activation and reduced levels of proteins related to the regulation of the complement cascade, platelet activation, and binding and uptake of ligands by scavenger receptors. No trial differences were found for cortisol and muscle damage biomarkers. Conclusions: CRAN versus PLAC juice resulted in a significant increase in CRAN-related metabolites but no differences in the gut microbiome. CRAN supplementation was associated with a transient and modest but significant post-exercise elevation in selected oxylipins and proteins associated with the innate immune system.

This study aimed to determine whether a polyphenol-rich cranberry beverage affects skin properties, lipids, and the microbiome in women using a randomized, double-blinded, placebo-controlled, cross-over design. Twenty-two women with Fitzpatrick skin types 2–3 were randomized to drink a cranberry beverage or placebo for six weeks. After a 21-day washout, they consumed the opposite beverage for six weeks. Six weeks of cranberry beverage significantly reduced UVB-induced erythema, improved net elasticity on the face and forearm, smoothness on the face, and gross elasticity on the forearm compared to the placebo. When stratified by age, these effects of the cranberry beverage were primarily observed in women >40 years old. SOD activities were improved after six weeks of cranberry beverage consumption compared to the placebo, while glutathione peroxide and TNF-α were improved compared to baseline. These effects were found to differ by age group. Skin lipid composition was modulated by both the cranberry beverage and the placebo. Cranberry beverages did not change α- or β-diversity but altered the abundance of several skin microbes at the species and strain level. Consumption of a cranberry beverage for six weeks improved specific skin properties and oxidative stress and modulated skin lipids and microbiome compared to placebo. [ABSTRACT FROM AUTHOR]

Emissions of carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4), particularly those from organic soils, need to be reduced in the context of climate change mitigation (CCM). Here, we estimated the greenhouse gas (GHG) fluxes from nutrient-poor organic soils in cranberry (Vaccinium macrocarpon) and highbush blueberry (Vaccinium corymbosum) plantations established on former peat extraction fields compared to active peat extraction fields and pristine raised bogs in Latvia. A two-year study (2016–2018) was conducted using the manual closed chamber method. In berry plantations and active peat extraction fields, annual net CO2 fluxes contributed the most to total GHG emissions, accounting for over 67%, and temperature had the most significant impact on CO2 fluxes. Conversely, annual CH4 fluxes were the primary contributor to total net GHG emissions in the pristine raised bog, which simultaneously acted as a slight CO2 sink. N2O fluxes were relatively low among all studied land use types. This study provided quantitative insights into the variation in GHG fluxes and the environmental variables influencing them, and the obtained data are valuable to estimate the impact of the establishment of berry plantations on former peat extraction fields on CCM in the hemiboreal region of Europe.

The sugars will eventually be exported transporter (SWEET) family is a novel class of sugar transporters that play a crucial role in plant growth, development, and responses to stress. Cranberry (Vaccinium macrocarpon Ait.) is a nutritious berry with economic importance, but little is known about SWEET gene family functions in this small fruit. In this research, 13 VmSWEET genes belonging to four clades were identified in the cranberry genome for the first time. In the conserved domains, we observed seven phosphorylation sites and four amino acid residues that might be crucial for the binding function. The majority of VmSWEET genes in each clade shared similar gene structures and conserved motifs, showing that the VmSWEET genes were highly conserved during evolution. Chromosomal localization and duplication analyses showed that VmSWEET genes were unevenly distributed in eight chromosomes and two pairs of them displayed synteny. A total of 79 cis-acting elements were predicted in the promoter regions of VmSWEETs including elements responsive to plant hormones, light, growth and development and stress responses. qRT-PCR analysis showed that VmSWEET10.1 was highly expressed in flowers, VmSWEET16 was highly expressed in upright and runner stems, and VmSWEET3 was highly expressed in the leaves of both types of stems. In fruit, the expression of VmSWEET14 and VmSWEET16 was highest of all members during the young fruit stage and were downregulated as fruit matured. The expression of VmSWEET4 was higher during later developmental stages than earlier developmental stages. Furthermore, qRT-PCR results revealed a significant up-regulation of VmSWEET10.2, under osmotic, saline, salt-alkali, and aluminum stress conditions, suggesting it has a crucial role in mediating plant responses to various environmental stresses. Overall, these results provide new insights into the characteristics and evolution of VmSWEET genes. Moreover, the candidate VmSWEET genes involved in the growth, development and abiotic stress responses can be used for molecular breeding to improve cranberry fruit quality and abiotic stress resistance.

IntroductionOne of the most prevalent bacterial diseases in both the general population and hospitals are urinary tract infections (UTIs). There is still conflicting scientific data about the usefulness of cranberry products in preventing UTIs. Our meta-analysis investigated whether the content of the main component, proanthocyanidins (PACs), in cranberries affects their ability to prevent UTIs.MethodsThe average daily intake of PACs has already been reported in previous randomized controlled trials (RCTs) that intended to investigate the effectiveness of cranberry in preventing UTIs, which were collected in our meta-analysis. The results were reported as the number of participants with UTIs. Random effect or fixed effect models were chosen for statistical analysis based on the heterogeneity.ResultsTen RCTs that matched the requirements were included. The results showed that when the daily intake of PACs was at least 36mg, the risk of UTIs was reduced by 18% (RR = 0.82, 95% CI = 0.69–0.98, p = 0.03). But when the daily intake of PACs was less than 36 mg, there was no statistical significance risk decrease (p = 0.39). The results of the sub-group analysis showed that cranberries only significantly reduced the risk of UTIs when the duration of cranberry product use falls between 12 and 24 weeks (RR = 0.75, 95% CI = 0.61–0.91, p = 0.004). Additionally, cranberries also significantly reduced the risk of UTIs only in subgroups that just included females (RR = 0.84, 95% CI = 0.71–0.98, p = 0.02).DiscussionThese findings showed a strong correlation between the daily use of the active ingredient PACs found in cranberry products and the prevention of UTIs. Our meta-analysis is the first to show that there are minimum daily PAC consumption intake levels in cranberry products and length of use considerations that are needed to achieve clinically relevant UTI prevention benefits.Systematic review registrationPROSPERO (CRD42023385398).

Abstract Objective To provide an overview of the available scientific evidence from in vitro studies regarding the effect induced by the flavonoids contained in grape seed extracts (GSE) and cranberry on the microbiological activity of Streptococcus mutans (S. mutans). Methods This systematic review was performed following the parameters of the PRISMA statement (Preferred Reporting Items for Systematic Reviews and Meta-Analysis). Electronic and manual searches were conducted using PubMed, ScienceDirect, Web of Science, EBSCO, and Cochrane databases. Reference lists of selected articles were reviewed to identify relevant studies. The search was not limited by year and was conducted solely in English. Eligible studies comprised publications describing in vitro studies that evaluated the effect of flavonoids derived from GSE and cranberry extracts on the microbiological activity of S. mutans. Common variables were identified to consolidate the data. Authors of this review independently screened search results, extracted data, and assessed the risk of bias. Results Of the 420 studies identified from the different databases, 22 publications were finally selected for review. The risk of bias was low in 13 articles and moderate in 9. The studies analyzed in this review revealed that cranberry extract has an inhibitory effect on the bacterial growth of S. mutans in ranges from 0.5 mg/mL to 25 mg/mL, and GSE exerts a similar effect from 0.5 mg/mL to 250 mg/mL. Additionally, the extracts or their fractions showed reduced biofilm formation capacity, decreased polymicrobial biofilm biomass, deregulation of glycosyltransferases (Gtf) B and C expression, and buffering of pH drop. In addition to adequate antioxidant activity related to polyphenol content. Conclusions The overall results showed that the extracts of cranberry and grape seed were effective in reducing the virulence factors of the oral pathogen. According to the data, proanthocyanidins are the active components in cranberry and grape seed that effectively resist S. mutans. They can inhibit the formation of insoluble polysaccharides in the extracellular matrix and prevent glycan-mediated adhesion, cohesion, and aggregation of the proteins in S. mutans. This suggests that these natural extracts could play an important role in the prevention of cariogenic bacterial colonization, as well as induce a decrease in their microbiological activity.

Background Red fruits are characterised by a particularly high content of bioactive compounds, e.g. anthocyanins, tannins, pectins, vitamins and minerals. Dietary supply of proper amounts of antioxidants is essential to reduce oxidative stress, and thus is an important element in the prevention of lifestyle diseases. Objective The aim of the study was to evaluate and compare the content of polyphenols in selected red fruit juices (chokeberry, elderberry, pomegranate, cranberry), as well as to assess the impact of storage time on the content of these compounds in the analysed samples. Material and Methods The research material consisted of 17 juices (100%): 3 chokeberry juices, 4 elderberry juices, 5 pomegranate juices and 5 cranberry juices, which differed in terms of the manufacturer, type, price range, country of origin and production method. The total polyphenol content was measured by spectrophotometry using the Folin�Ciocalteu reagent. The procedure was based on a modified method described by Waterhouse. Active acidity (pH) was measured with the potentiometric method using a pH-meter and the sucrose content was measured using a refractometer. Results The highest mean content of polyphenolic compounds was found in chokeberry and elderberry juices. Juice storage time did not reduce the mean content of polyphenolic compounds. The highest sucrose content was found in chokeberry juices and the lowest in cranberry juice. Conclusions Chokeberry and elderberry juices had the highest content of polyphenols among the tested products. Juices stored after opening in accordance with the manufacturer’s instructions (at 4°C) do not lose their nutritional properties.

The treatment of infectious diseases typically includes the administration of anti-infectives; however, the increasing rates of antimicrobial resistance (AMR) have led to attempts to develop other modalities, such as antimicrobial peptides, nanotechnology, bacteriophages, and natural products. Natural products offer a viable alternative due to their potential affordability, ease of access, and diverse biological activities. Flavonoids, a class of natural polyphenols, demonstrate broad anti-infective properties against viruses, bacteria, fungi, and parasites. Their mechanisms of action include disruption of microbial membranes, inhibition of nucleic acid synthesis, and interference with bacterial enzymes. This review explores the potential of natural compounds, such as flavonoids, as an alternative therapeutic approach to combat infectious diseases. Moreover, it discusses some commonly used natural products, such as cranberry and D-mannose, to manage urinary tract infections (UTIs). Cranberry products and D-mannose both, yet differently, inhibit the adhesion of uropathogenic bacteria to the urothelium, thus reducing the likelihood of UTI occurrence. Some studies, with methodological limitations and small patient samples, provide some encouraging results suggesting the use of these substances in the prevention of recurrent UTIs. While further research is needed to determine optimal dosages, bioavailability, and potential side effects, natural compounds hold promise as a complementary or alternative therapeutic strategy in the fight against infectious diseases.

The phytochemical diversity and potential health benefits of V. oxycoccos and V. macrocarpon fruits call for further scientific inquiry. Our study aimed to determine the phytochemical composition of extracts from these fruits and assess their antioxidant, antibacterial, and anticancer properties in vitro. It was found that the ethanolic extracts of V. oxycoccos and V. macrocarpon fruits, which contained more lipophilic compounds, had 2–14 times lower antioxidant activity compared to the dry aqueous extracts of cranberry fruit, which contained more hydrophilic compounds. All tested cranberry fruit extracts (OE, OW, ME, and MW) significantly inhibited the growth of bacterial strains S. aureus, S. epidermidis, E. coli, and K. pneumoniae in vitro compared to the control. Cytotoxic activity against the human prostate carcinoma PPC-1 cell line, human renal carcinoma cell line (CaKi-1), and human foreskin fibroblasts (HF) was determined using an MTT assay. Furthermore, the effect of the cranberry fruit extract samples on cell migration activity, cancer spheroid growth, and viability was examined. The ethanolic extract from V. macrocarpon fruits (ME) showed higher selectivity in inhibiting the viability of prostate and renal cancer cell lines compared to fibroblasts. It also effectively hindered the migration of these cancer cell lines. Additionally, the V. macrocarpon fruit extract (ME) demonstrated potent cytotoxicity against PPC-1 and CaKi-1 spheroids, significantly reducing the size of PPC-1 spheroids compared to the control. These findings suggest that cranberry fruit extracts, particularly the ethanolic extract from V. macrocarpon fruits, have promising potential as natural remedies for bacterial infections and cancer therapy.

Introduction and Purpose Urinary tract infections (UTIs) are a prevalent health issue caused primarily by uropathogenic Escherichia coli (UPEC) and other pathogens, affecting millions annually. These infections encompass lower (cystitis) and upper (pyelonephritis) tract manifestations, presenting with symptoms ranging from dysuria to severe complications like sepsis. Traditional antibiotic treatments, while effective, are increasingly challenged by resistance and adverse effects, necessitating exploration of alternative therapies. Cranberry-derived compounds, particularly proanthocyanidins (PACs), are known for their ability to inhibit bacterial adhesion to uroepithelial cells, a critical step in UTI pathogenesis. Clinical studies suggest that cranberry products may reduce UTI incidence, especially in vulnerable populations such as women and catheterized patients. Probiotics, specifically lactobacilli, contribute to urogenital health by competing with uropathogens for epithelial cell binding sites and producing antimicrobial substances. Emerging research highlights the potential synergistic benefits of combining cranberry extracts with probiotics in UTI prevention strategies. Material and Methods This review is based on articles from the PubMed database, covering the years 2004-2023, using keywords: urinary tract infections, cranberry, probiotics, E. Coli, antibiotics Conclusions Cranberry products and probiotics offer promising non-antibiotic approaches for UTI prevention, targeting fundamental aspects of bacterial pathogenesis. While preliminary studies indicate promising outcomes, rigorous clinical trials are essential to validate these combinations and optimize therapeutic protocols. Further research is warranted to identify specific bioactive compounds within cranberries, standardize probiotic formulations, and establish comprehensive guidelines for their clinical use in UTI management.

The objectives of this research were to analyze anthocyanins in blue honeysuckle (Lonicera caerulea L.), bilberry (Vaccinium vitis-idaea L), and cranberry (Vaccinium macrocarpon Ait.), using HPLC-ESI-QTOF-MS2, Fourteen, fifteen, and eight anthocyanins were identified in blue honeysuckle, bilberry, and cranberry, respectively. Cyanidin-3-glucoside (C3G) and peonidin-3-glucoside were detected in all three types of berries, with blue honeysuckle showing the highest C3G content at 5686.28 mg/100 g DW. Total phenolic content (TPC) and total flavonoid content (TFC), along with ABTS, DPPH, and FRAP assays, were measured. Blue honeysuckle exhibited the highest levels of TPC and TFC. The SOD, POD, and CAT activities in blue honeysuckle were 1761.17 U/g, 45,525.65 U/g, and 1043.24 U/g, respectively, which were significantly superior to those in bilberry and cranberry. The antioxidant mechanisms of these enzymes were investigated by molecular docking, C3G showed a higher affinity for POD, confirming the effectiveness of C3G as an antioxidant.

A couple visited the IVF clinic to seek treatment for primary infertility. A 45-year-old quadragenarian female and her 49-year-old male partner were recommended infertility treatment after 2 years of unsuccessful attempts to conceive. The woman had a recent history of dengue and chickenpox. The male partner was advised to do a semen analysis. The report showed asthenoteratozoospermia and the semen sample viscous. On the other hand, the female was diagnosed with hypothyroidism. The male patient was given a 3-month medication treatment that included probiotic supplements and cranberry juice to treat bacterial infections and urinary tract infections. The male partner also advised medication, and regular semen analysis was performed after every 3 months. The treatment plan included intrauterine insemination (IUI), which increased the possibility of pregnancy. Fourteen days following the IUI and pregnancy test, the outcomes were positive. The case illustrates the difficulties in treating primary infertility by combining reproductive procedures, medication, and lifestyle modifications. Regularly monitoring semen quality and hormonal levels is crucial in assessing treatment success. The positive outcome of IUI suggests the effectiveness of the fertility treatment plan.

This study aims to update the evidence and clarify whether cranberry possesses lipid-lowering and hypoglycemic properties in humans. PubMed, Web of Science, and Scopus were searched to identify relevant articles published up to December 2023. In total, 3145 publications were reviewed and 16 of them were included for qualitative synthesis and meta-analysis. Stata 15.0 and Review Manager 5.4 were applied for statistical analyses. The results revealed a significant decrease in the total cholesterol to high-density lipoprotein cholesterol ratio (TC/HDL-C) (MD = −0.24; 95% CI: −0.45, −0.04; peffect = 0.02) and homeostasis model assessment of insulin resistance (HOMA-IR) (MD = −0.59; 95% CI: −1.05, −0.14; peffect = 0.01) with cranberry consumption. However, it did not influence total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG), fasting blood glucose (FBG), glycated hemoglobin (HbA1c), and fasting insulin. In subgroup analysis, cranberry consumption in dried form (capsules, powder, and tablets) was found to significantly decrease the fasting insulin level (three studies, one hundred sixty-five participants, MD = −2.16; 95% CI: −4.24, −0.07; peffect = 0.04), while intervention duration, health conditions, and dosage of polyphenols and anthocyanins had no impact on blood lipid and glycemic parameters. In summary, cranberry might have potential benefits in regulating lipid and glucose profiles. [ABSTRACT FROM AUTHOR]

The Electrodialysis with Filtration Membrane (EDFM) system has shown promise in juice enrichment, but further optimization is needed. This study evaluated the effect of processing duration (3 and 6 h) on juice composition, process efficiency, and membrane fouling. Results demonstrated a significant impact of processing time on juice composition, especially anthocyanin and mineral content. Two anthocyanin-depleted juices (−18.94% and −30.70%) and two anthocyanin-enriched juices (26.21% and 44.21%) were produced. Similar energy (1512.13 Wh/g of anthocyanins) was required to migrate equivalent amounts of anthocyanins over both time periods, with no impediment due to fouling observed, although the system’s resistance increased (2.5-fold after 3 h, 3.2-fold after 6 h). Membrane fouling was characterized through conductivity, thickness, ATR-FTIR, SEM-EDX, and foulant identification. Minimal anthocyanin accumulation occurred on cation-exchange membranes (CEM), while anthocyanins and PACs concentrated within the filtering layer of filtration membranes (FM). However, fouling did not increase with longer processing. Structural alterations were noted in anion-exchange membranes (AEMs), suggesting instability under high electric fields. Overall, EDFM effectively enriched cranberry juice with anthocyanins, but further research is necessary to address AEM degradation under limiting current density conditions.

Emissions of carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4), particularly those from organic soils, need to be reduced in the context of climate change mitigation (CCM). Here, we estimated the greenhouse gas (GHG) fluxes from nutrient-poor organic soils in cranberry (Vaccinium macrocarpon) and highbush blueberry (Vaccinium corymbosum) plantations established on former peat extraction fields compared to active peat extraction fields and pristine raised bogs in Latvia. A two-year study (2016–2018) was conducted using the manual closed chamber method. In berry plantations and active peat extraction fields, annual net CO2 fluxes contributed the most to total GHG emissions, accounting for over 67%, and temperature had the most significant impact on CO2 fluxes. Conversely, annual CH4 fluxes were the primary contributor to total net GHG emissions in the pristine raised bog, which simultaneously acted as a slight CO2 sink. N2O fluxes were relatively low among all studied land use types. This study provided quantitative insights into the variation in GHG fluxes and the environmental variables influencing them, and the obtained data are valuable to estimate the impact of the establishment of berry plantations on former peat extraction fields on CCM in the hemiboreal region of Europe.

Urinary tract infections (UTIs), primarily caused by uropathogenic Escherichia coli (UPEC), have an unclear impact on bladder mucosal physiology. This study investigates UPEC's effects on the urothelium and lamina propria using an ex vivo porcine bladder model. Bladder mucosal strips were analysed for contractile responses to acetylcholine, serotonin, and neurokinin A. Given rising antibiotic resistance, non-antibiotic agents such as cranberry and d -mannose were also evaluated for their potential to prevent UPEC-induced damage. The findings of the current study revealed that UPEC significantly compromised urothelial integrity, barrier function, and permeability, with loss of urothelial cells, uroplakins, and tight junction protein ZO-1 expression. Additionally, infected bladders exhibited a markedly enhanced contractile response to serotonin compared to uninfected controls. Notably, neither cranberry nor d -mannose offered protection against UPEC-mediated damage or mitigated the heightened serotonin-induced contractility. This study provides novel insights into how UPEC disrupts bladder cell biology and highlights the possible involvement of serotonin in the pathophysiology of UTIs. [ABSTRACT FROM AUTHOR]

Introduction: The main function of the urinary tract is to form an impermeable barrier against urinary solutes and bacteria. However, this barrier can be compromised by urinary tract infections, most commonly caused by uropathogenic Escherichia coli (UPEC). This can result in damage to the epithelial barrier, leading to decreased epithelial thickness, loss of tight junctions, loss of epithelial integrity, and apoptosis. Due to the rise in antimicrobial resistance, there is worldwide interest in exploring non-antibiotic agents as alternative therapy. Methods: Using the Madin-Darby canine kidney (MDCK) cell line, a widely accepted epithelial cell model for the urinary tract, and the UPEC strain UTI89, this paper aimed to investigate the impact of UPEC on cell integrity, permeability, and barrier functions, and determine whether cranberry, D-mannose and ibuprofen could counteract the effects induced by UPEC. Furthermore, the study examined the protective potential of these agents against UPEC-induced increase in reactive oxygen species (ROS) production and programmed death-ligand 1 (PD-L1) expression. Results: The results demonstrated that UTI89 caused a marked reduction in cell viability and monolayer integrity. Cranberry (3mg/mL) was protective against these changes. In addition, cranberry exhibited protective effects against UPEC-induced damage to cell barrier integrity, escalation of oxidative stress, and UPEC/TNFa-triggered PDL1 expression. However, no effect was observed for D-mannose and ibuprofen in alleviating UPEC-induced cell damage and changes in ROS and PD-L1 levels. Conclusion: Overall, cranberry, but not D-mannose or ibuprofen, has a protective influence against UPEC associated damage in urinary epithelial cells. [ABSTRACT FROM AUTHOR]

Pyrolysis is a thermochemical conversion process producing biochar, gas, and bio-oil at high temperatures in an oxygen-free environment. Specific pyrolysis conditions enable a significant production of the aqueous phase of bio-oil, commonly known as wood vinegar. Wood vinegar contains organic compounds such as acetic acid and phenols derived from bio-oil. These compounds have herbicidal properties against weeds and biostimulant properties for plant growth. This study reveals the potential for efficient management of cranberry residues consisting of stems and leaves by producing wood vinegar through pyrolysis at 475 °C with a humidity level of 20%. Membrane separation of wood vinegar, using nanofiltration (NF) and reverse osmosis (RO) membranes, yielded phenols in the retentate and acetic acid in the permeate with respective yields of 44.7% with NF membrane and 45% with RO membrane. Biostimulation tests using 2% of the retentate showed significant germination rates for basil, sage, and parsley plants. Additionally, using 40 mL of the wood vinegar permeate (30 mL injected at the base and 10 mL sprayed on the leaves) resulted in leaf damage, measured by conductivity (leakage of electrolytes released by the leaves), of 62.3% and 20.5% respectively for quack grass and white clover, two weeds found in cranberry production.

Brown algae are a source of hydrothermal extracts that can serve as an effective raw material for instant beverages. This article offers new formulations of functional instant beverages made of concentrated fruit juices and algal extracts of Saccharina japonica and Sargassum miyabei Yendo. The research objective was to define their bioactive and antioxidant profiles. The research featured S. miyabei Yendo and S. japonica brown algae from the Far East of Russia, their dry hydrothermal extracts, and instant drinks based on these extracts combined with concentrated juices of cranberry, sea buckthorn, and chokeberry. The list of methods included spectrophotometry, high-performance liquid chromatography, and gas chromatography. The hydrothermal algal extracts of S. miyabei and S. japonica were rich in fucoidan, phenolic compounds, and iodine. The new instant beverages underwent a sensory evaluation. They contained iodine, phenolic compounds, vitamins (ascorbic acid), fucoidan, pectin, flavonoids, anthocyanins, catechins, carotenoids, and tocopherols. All the samples could be classified as functional, but the best antiradical properties belonged to the sample with black chokeberry juice and S. miyabei. The new functional instant beverages had a high radical-binding activity, which reached 96.3%. One portion (200 mL) covered 27–30% of the recommended daily intake of iodine and 22–50% of vitamin C. The obtained results prove that instant beverages made of S. japonica and S. miyabei Yendo can be used as functional products.

The treatment of infectious diseases typically includes the administration of anti-infectives; however, the increasing rates of antimicrobial resistance (AMR) have led to attempts to develop other modalities, such as antimicrobial peptides, nanotechnology, bacteriophages, and natural products. Natural products offer a viable alternative due to their potential affordability, ease of access, and diverse biological activities. Flavonoids, a class of natural polyphenols, demonstrate broad anti-infective properties against viruses, bacteria, fungi, and parasites. Their mechanisms of action include disruption of microbial membranes, inhibition of nucleic acid synthesis, and interference with bacterial enzymes. This review explores the potential of natural compounds, such as flavonoids, as an alternative therapeutic approach to combat infectious diseases. Moreover, it discusses some commonly used natural products, such as cranberry and D-mannose, to manage urinary tract infections (UTIs). Cranberry products and D-mannose both, yet differently, inhibit the adhesion of uropathogenic bacteria to the urothelium, thus reducing the likelihood of UTI occurrence. Some studies, with methodological limitations and small patient samples, provide some encouraging results suggesting the use of these substances in the prevention of recurrent UTIs. While further research is needed to determine optimal dosages, bioavailability, and potential side effects, natural compounds hold promise as a complementary or alternative therapeutic strategy in the fight against infectious diseases.

The phytochemical diversity and potential health benefits of V. oxycoccos and V. macrocarpon fruits call for further scientific inquiry. Our study aimed to determine the phytochemical composition of extracts from these fruits and assess their antioxidant, antibacterial, and anticancer properties in vitro. It was found that the ethanolic extracts of V. oxycoccos and V. macrocarpon fruits, which contained more lipophilic compounds, had 2–14 times lower antioxidant activity compared to the dry aqueous extracts of cranberry fruit, which contained more hydrophilic compounds. All tested cranberry fruit extracts (OE, OW, ME, and MW) significantly inhibited the growth of bacterial strains S. aureus, S. epidermidis, E. coli, and K. pneumoniae in vitro compared to the control. Cytotoxic activity against the human prostate carcinoma PPC-1 cell line, human renal carcinoma cell line (CaKi-1), and human foreskin fibroblasts (HF) was determined using an MTT assay. Furthermore, the effect of the cranberry fruit extract samples on cell migration activity, cancer spheroid growth, and viability was examined. The ethanolic extract from V. macrocarpon fruits (ME) showed higher selectivity in inhibiting the viability of prostate and renal cancer cell lines compared to fibroblasts. It also effectively hindered the migration of these cancer cell lines. Additionally, the V. macrocarpon fruit extract (ME) demonstrated potent cytotoxicity against PPC-1 and CaKi-1 spheroids, significantly reducing the size of PPC-1 spheroids compared to the control. These findings suggest that cranberry fruit extracts, particularly the ethanolic extract from V. macrocarpon fruits, have promising potential as natural remedies for bacterial infections and cancer therapy.

To optimize cranberry juice enrichment, correlation between physicochemical properties of filtration membranes (FM) and anthocyanin migration was investigated during electrodialysis with filtration membranes (EDFM) using redundancy (RDA) and multivariate regression (MRGA) analyses. Six polyether sulfone (PES) and polyvinylidene fluoride (PVDF) membranes with molecular weight cut-offs between 150 and 500 kDa, commercially available at large scale, were characterized in terms of nine physicochemical characteristics and used for EDFM. The highest migration of total anthocyanin was obtained with PVDF 250 kDa, with a global migration rate of 3.5 ± 0.4 g/m2·h. RDA showed that two FM properties (mesopore porosity and hydrophilic porosity) were significantly negatively correlated to the anthocyanin’s migration and explained 67.4% of their total variation in migration. Predictive MRGA models were also developed for each anthocyanin based on these significant FM properties. A combination of intermolecular interactions may lead to binding in a cooperative and synergistic mode and hinder the anthocyanin migration.

Cranberry is abundantly rich in anthocyanins, a type of flavonoid with potent antioxidant properties and the resistance against certain diseases. In this study, anthocyanin-rich cranberry extract was extracted, purified, and its components were analyzed. 92.18 % of anthocyanins was obtained and the total content of anthocyanins was 302.62 mg/g after AB-8 resin purification. Quantification analysis showed that the extract mainly contained cyanidin-3-galactoside, procyanidin B2 and procyanidin B4. Then we explored its effects on dextran sulfate sodium (DSS)-induced inflammatory bowel disease (IBD) in mice. The supplementation of cranberry extract resulted in an alleviation of IBD symptoms, evidenced by improvements in the disease activity index (DAI), restoration of colon length and colonic morphology. Cranberry extract reversed the elevated iron and malondialdehyde (MDA) levels and restored glutathione (GSH) levels in IBD mice. Further analysis revealed that cranberry modulated ferroptosis-associated genes and reduced expression of pro-inflammatory cytokines. Although cranberry influenced the intestinal flora balance by reducing Proteobacteria and Escherichia-Shigella, and increasing Lactobacillus, as well as enhancing SCFAs content, these effects were not entirely dependent on intestinal flora modulation, as indicated by antibiotic intervention and fecal microbiota transplantation (FMT) experiments. In conclusion, our findings suggest that the beneficial impact of cranberry extract on IBD may primarily involve the regulation of colonic ferroptosis, independent of significant alterations in intestinal flora.

COVID-19 disease is an acute viral infection illness of the airway system resulting from the SARS-CoV-2 virus. Cranberry is an evergreen group of dwarf shrubs of the Vaccinium Oxycoccus. The most important pharmacological effects of cranberry are related to its composition liking of quercetin, flavonols, and proanthocyanidins. cranberry had numerous pharmacological activities encompassing antioxidant, cardioprotective, antibacterial, anticancer, antiviral, and regulated glucose levels. This research aimed to estimate the potential activity of cranberry to enhance the efficacy of standard therapy for COVID-19 infection. A total of 30 patients with age ≥ 18 years suffering from mild to moderate COVID-19 pneumonia volunteered to do this study, allocated into two groups. The first group managed standard treatment only according to the National Institutes of Health, while the second group managed standard treatment plus cranberry 1000 mg capsule per day for 7 days. Each patient was assessed individually and follow up for 10 days. Cranberry significantly enhanced the effect of standard COVID – 19 therapies by rapidly relieving clinical symptoms of COVID – 19 infections and significantly lowered the count of WBC, CRP, D-Dimer, and ferritin in comparison with patients who only received STD therapy at P

According to the opinion of nutritionists, human health depends on a number of factors: the structure of nutrition by 40–45%, genetics by 18%, the state of health care by 10%, environmental factors by 8%, from other reasons – by 19–24%. That is, the nutrition factor is the leading one, and the health of the nation mainly depends on it. In recent decades, the pace of life of people in the developed countries of the world has accelerated significantly, and this is a significant lever in favor of the use of so-called "fast foods". Their composition includes peanut paste, which is very popular among the population of many countries, and its modifications containing various additives. The purpose of the work was to substantiate the feasibility of obtaining paste from domestic raw materials – pumpkin seeds with the addition of berry powders, as well as the characteristics of the obtained products. Analysis of the amino acid composition of pumpkin seed protein paste, its comparison with that of peanuts and the FAO/WHO standard shows that pumpkin seed protein is characterized by greater biological value. The oil components of the pumpkin and peanut seed pastes had almost the same qualitative fatty acid composition, but the latter was significantly inferior in terms of the ratio of different groups of acids – it was characterized by a low content of polyunsaturated linoleic acid and at the same time a large amount of saturated acids. Peanut paste had a higher oil content and higher calorie content compared to pumpkin seed paste. Three samples were obtained on the basis of pumpkin seed paste: 25% of the mass of the product was replaced with berry powders, namely dried and crushed viburnum, cranberry, sea buckthorn berries. They outperformed the original sample in terms of their sensory properties and had a reduced calorie content compared to it. The results of the study of changes in the physico-chemical parameters of the oil component of products during storage indicate that the introduction of berry powders significantly slows down the process of its oxidation. The best result was observed for the sample containing sea buckthorn powder, which is probably due to its high content of tocopherol, an effective antioxidant.

The impact of the growth environment on the production of health-promoting phytochemicals in cranberry fruit (Vaccinium macrocarpon Aiton) is not well established despite increased production worldwide. We investigated the secondary metabolite composition among the cranberry fruit of nine cultivars produced in two major coastal North American growing regions that differ in climate. Using 1H NOESY NMR to generate metabolic fingerprints, principal component analysis revealed variation between the two regions and identified likely contributing metabolites. Triterpenoids ursolic and oleanolic acid, as well as citric and malic acids, were quantified using 1H qNMR, and anthocyanins and flavonols were determined by HPLC-DAD. Total proanthocyanidins (PACs), total soluble phenolics, and DPPH free-radical scavenging antioxidant activity were also evaluated. Across all cultivars, anthocyanins, flavonols, and total phenolic content were significantly higher in West Coast fruit than East Coast fruit, correlating with a regional trend of higher antioxidant activity in fruit grown on the West Coast. The opposite trend was observed for triterpenoids and organic acids, which were significantly higher across cultivars in East Coast fruit. These trends persisted over two growing seasons. The study demonstrates that climate plays an important role in the production of antioxidant and anti-inflammatory phytochemicals in cranberry plants. [ABSTRACT FROM AUTHOR]

Cranberry offers numerous cardiovascular benefits. According to several studies, this fruit promotes the oxidation of low‐density lipoprotein, enhances high‐density lipoprotein, reduces platelet coagulation, and improves vascular activity. Albino male rats were divided into five groups (n = 5 per group). The control group received intraperitoneal administration of normal saline. The second group was injected with metaproterenol (MET) 3 days a week for 4 weeks. The third, fourth, and fifth groups were given cranberry extract in doses of 75, 100, and 150, respectively, along with heart‐damaging drugs. Blood samples were collected and sent to the laboratory on the fourth weekend and 1 week after completing the injections in the fourth week (the sixth weekend) for analyzing serum factors such as cardiac creatine kinase MB, cardiac troponin I (cTnI), and aspartate aminotransferase (AST). The serum activity of the cardiac evaluation parameters in the fourth week demonstrated a highly significant correlation among the groups with respect to AST and cTnI (p <.001). Additionally, a significant relationship was observed between AST and cTnI within the target groups (p <.05). Ultimately, the findings indicated that the consumption of cranberry extract, due to its impact on heart function, could effectively modify serum indicators associated with heart damage. The utilized extract also exhibited efficacy, albeit with variable effects. Therefore, it is recommended to use cranberry extract synergistically with other chemical and herbal medications to achieve more sustained effects. [ABSTRACT FROM AUTHOR]

Biscuits are one of the most consumed bakery products that contain a high content of fat, sugar, and different additives that may cause various health problems. This has led to an increased focus on enriching bakery products with plant extracts to improve their nutritional and sensory properties. The objective of the current work was to investigate the effect of replacing wheat flour with plant extracts such as blueberry and cranberry (at concentrations of 3%, 6%, and 9%) and compare with control biscuits regarding the physico-chemical and color parameters. In addition, sensory analysis was conducted to determine the consumer acceptability of the enriched biscuits. The enrichment of biscuits with blueberry powder significantly increased the moisture content and decreased pH values (p < 0.05). Similarly, cranberry-enriched biscuits had a significantly higher moisture content, water activity, and decreased pH values compared to control samples (p < 0.05). On the other hand, enrichment of biscuits with either blueberry or cranberry powder significantly decreased lightness (L*), yellowness (b*), chroma value (C*), and h-value (h) but increased the redness values (a* value) of samples (p < 0.05). Our results showed that with increasing concentrations of plant extract addition in biscuits, the sensory attributes such as odor and taste were significantly improved. The results of the study suggest that the addition of plant extracts to biscuits improved their physico-chemical and sensory properties. [ABSTRACT FROM AUTHOR]

Escherichia coli is the most common pathogen isolated from the urine of dogs with urinary tract infections (UTIs). While there are many studies in humans investigating the potential for the prevention of UTIs by dietary consumption of cranberry, few analogous studies have been carried out in dogs.

Background: The present study formulates and evaluates a polyberry gel comprising extracts of cranberry (Vaccinium macrocarpon) and brindle berry (Garcinia cambogia) in patients suffering from chronic periodontitis. Materials and Methods: The polyberry gel was evaluated for various physicochemical parameters, in vitro permeability and stability, and the active phytoconstituents were quantified by High-performance thin layer chromatography (HPTLC). Total phenolic content, total antioxidants, and ascorbic acid were estimated in the two extracts by in vitro assays. Patients suffering from chronic periodontitis with probing pocket depth (PPD) up to 5 mm were divided into 3 groups of 21 patients each and treated with scaling and root planing (SRP) or SRP followed by subgingival placement of polyberry gel or tetracycline fibers (standard). Plaque Index (PI), Gingival Index (GI), PPD, Clinical Attachment Level (CAL), and the salivary aspartate aminotransferase (AST) and C-reactive protein (CRP) levels were recorded at baseline and after 1 month. Results: A significant (P < 0.01) reduction in the periodontic disease parameters was observed in the standard and gel-treated groups between their baseline and 1-month time-interval readings. The polyberry gel treatment significantly (P < 0.05 for AST and P < 0.01 for the rest) attenuated the periodontitis-elevated PI, GI PPD, CAL, AST and CRP levels when compared with SRP at the end of the study and was comparable with tetracycline. Conclusion: The amelioration of periodontitis and gingival inflammation may be attributed to the potent antioxidant activity of the polyphenolic phytoconstituents of the gel. The polyberry gel may thus be used as a safe adjunct to SRP/tetracycline in chronic periodontitis.

Fungi are associated with the European cranberry (Vaccinium oxycoccos L.) and play important roles in plant growth and disease control, especially in cranberry yields. This article presents the results of a study which was aimed to investigate the diversity of fungi found on different clones and cultivars of the European cranberry grown in Lithuania, causing twigs, leaf diseases and fruit rots. In this study seventeen clones and five cultivars of V. oxycoccos were selected for investigation. Fungi were isolated via the incubation of twigs, leaves and fruit on a PDA medium and identified according to their cultural and morphological characteristics. Microscopic fungi belonging to 14 genera were isolated from cranberry leaves and twigs, with Physalospora vaccinii, Fusarium spp., Mycosphaerella nigromaculans and Monilinia oxycocci being the most frequently isolated fungi. 'Vaiva' and 'Žuvinta' cultivars were the most susceptible to pathogenic fungi during the growing season. Among the clones, 95–A–07 was the most susceptible to Phys. vaccinii, 95–A–08 to M. nigromaculans, 99–Ž–05 to Fusarium spp. and 95–A–03 to M. oxycocci. Microscopic fungi belonging to 12 genera were isolated from cranberry berries. The most prevalent pathogenic fungi M. oxycocci were isolated from the berries of the cultivars 'Vaiva' and 'Žuvinta' and clones 95–A–03 and 96–K–05. [ABSTRACT FROM AUTHOR]

Urinary tract infections (UTI), which are among the most frequent cases of infectious diseases, mainly affect women. The most common treatment approach involves the use of antibiotics, although this solution is not always the most suitable, mainly because of the resistance that bacterial strains develop. Proanthocyanidins are a class of polyphenols, abundantly contained in cranberry extracts, which have shown beneficial effects in the treatment of urinary tract infections, due to their anti-adhesive properties toward bacteria, with respect to the membranes of the cells of the urothelium and intestine, thus reducing their virulence. In this work, we demonstrate via microscopy and scattering measurements how a mixture of cranberry and chondroitin sulfate can form a crosslinked structure with barrier properties. By using a design of experiment (DOE), we optimized the mass ratio to obtain a precipitate between cranberry extract and chondroitin sulfate in the presence of N-acetylcysteine and hyaluronic acid. By using transepithelial electrical resistance (TEER) chambers, we confirmed the barrier properties of the best mixture obtained with the DOE. Lastly, the antibiofilm action was investigated against five strains of Escherichia coli with different antibiotic sensitivity. The precipitate displayed a variable inhibitory effect in biofilm formation with major effects in UTI with an antibiotic resistance profile. [ABSTRACT FROM AUTHOR]

This study was conducted to evaluate the effects of long-term administration of a new herbal composition of leuzea and cranberry meal extracts at a dose of 70:500 mg/kg in healthy and pathological mice. After 4 weeks of daily composition administration to healthy CD-1 mice and C57BL/6 mice with diet-induced metabolic syndrome, oral glucose tolerance test (OGTT), serum biochemical examination and histology of internal organs were performed. Additionally, histological examination of white and brown adipose tissue was performed to evaluate the ability of the composition to prevent abdominal obesity in C57BL/6Ay (agouti yellow) mice. The results showed that the composition increased tissue sensitivity to glucose in healthy CD-1 mice; at the same time, it did not worsen the course of pathological processes in pathological mice. In both cases, the application of the developed composition was safe and contributed to the restoration of metabolic parameters. [ABSTRACT FROM AUTHOR]

This review summarises the material covered during a workshop entitled “Natural Products as Treatments for Urinary Incontinence” that was presented at the online ICS (Melbourne) annual conference held in 2021. The clinical and scientific evidence of the effectiveness of naturally sourced treatments such as traditional Chinese medicines, phytoestrogens and saw palmetto for lower urinary tract symptoms are discussed, and also the use of cranberry and D-mannose for the treatment of bacterial infections of the urinary tract. The workshop and this review finish with a look towards the future and a discussion of potential treatments to repair the barrier function of the urothelium, an action that may be useful in conditions such as interstitial cystitis/bladder pain syndrome.

Aim. To determine the parameters of standardization of a dry extract from large cranberry (Oxycoccus macrocarpus (Ait.)) leaves and a dry extract modified with arginine and develop projects of Drug Quality Control Methods (DQCM) for these substances. Materials and methods. The study object was dry extracts from large cranberry leaves. Leaves were harvested in October 2021 in the Zhytomyr region (Kostivtsi village, 50.326862437345945, 29.54310845594284). The extracts were obtained with a 50 % solution of ethyl alcohol in the ratio of 1:30 by double maceration. Half of the combined extract was dried to a dry extract (Extract 1), and the other half was modified with arginine in the threefold equimolar amount relative to the total amount of phenolic compounds and evaporated to a dry extract (Extract 2). Standard pharmacopoeial methods were used to determine standardization parameters. The quantitative determination was carried out using the spectrophotometric method by the content of flavonoids calculated with reference to hyperoside and hydroxycinnamic acids calculated with reference to chlorogenic acid on an Evolution 60S spectrophotometer (Thermo Scientific Spectronic, USA). Results and discussion. The parameters of standardization of dry extracts from large cranberry leaves were determined. The project of DQCM was proposed according to the following indicators: description, solubility, identification using the thin-layer chromatography method (by the content of flavonoids, hydroxycinnic acids and arginine), loss on drying, the residual amount of organic solvents (ethanol), microbiological purity, and the content of heavy metals. The assay was carried out using spectrophotometry by the content of flavonoids and derivatives of hydroxycinnic acids. Three batches of the extracts obtained, which fully corresponded to the projects of DQCM developed, were analyzed. Conclusions. The parameters of standardization of dry extracts from large cranberry leaves have been determined, and projects of DQCM for the substances obtained have been developed. It is the basis for creating new medicines for the correction of insulin-resistant conditions in Type 2 diabetes mellitus.

The problem of type 2 diabetes due to its prevalence, severity, and complications is one of the most pressing in the world. Plants of the genus Vaccinium are promising sources for the creation of hypoglycemic and hypolipidemic medicines. Studies have shown that the extract from cranberry leaves, obtained with 50 % ethanol solution has prospects to be used for correcting insulin resistance. Therefore, for creating new medicines based on cranberry leaves, it is necessary to determine the optimal parameters of biologically active substances (BAS) extraction from this raw material. The aim of the research is to determine the parameters of BAS extraction from cranberry leaves (Oxycoccus macrocarpus (Ait.) Pursh) for creating a new dry extract with hypoglycemic activity. Materials and methods. The object of the study was cranberry leaves. Extracts from the leaves were obtained with 50 % ethanol solution in a ratio of 1:10; 1:15; 1:20; 1:25; 1:30 and 1:35 by maceration at room temperature for 8 hours. The extraction was repeated four times with new portions of the extractant, collecting each extract separately. Identification of phenolic compounds was performed by thin-layer chromatography. An assay of phenolic compounds was carried out by spectrophotometric methods. The mass transfer coefficient of each stage (miBAS/Viextragent) was calculated for each indicator and the dependence of these factors on the extraction multiplicity to determine the rational extraction was derived using the software Statistics. Results. Gallic and chlorogenic acids, rutin, quercetin, and hyperoside were detected on TLC of cranberry leaves extracts in comparison with standard samples of substances. The content of the sum of hydroxycinnamic acid derivatives in terms of chlorogenic acid, the number of flavonoids in terms of rutin, and the content of the sum of phenolic compounds in terms of gallic acid were determined. It was established that the exhaustive extraction of BAS with 50 % ethanol solution from the cranberry leaves provides a ratio of 1 to 100–110. It was rational to carry out BAS extraction from cranberry leaves in a ratio of 1:10 twice, this would ensure the maximum yield of BAS at the minimum cost of the extractant. Conclusions. It was found that was rational to extract BAS with 50 % ethanol solution from cranberry leaves in a ratio of 1:10 twice using mathematical and statistical methods. It would be used in the future in the development of extract technology.

Cranberries have known anti-inflammatory properties, which extend their benefits in the context of several chronic diseases. These benefits highly rely on the polyphenol profile of cranberries, one of few foods rich in A-type proanthocyanidin (PAC). A-type PAC comprises flavan-3-ol subunits with an additional interflavan ether bond in the conformational structure of the molecule, separating them from the more commonly found B-type PAC. PACs with a degree of polymerization higher than three are known to reach the colon intact, where they can be catabolyzed by the gut microbiota and biotransformed into lower molecular weight organic acids that are available for host absorption. Gut microbiota-derived metabolites have garnered much attention in the past decade as mediators of the health effects of parent compounds. Though, the mechanisms underlying this phenomenon remain underexplored. In this review, we highlight emerging evidence that postulates that polyphenols, including ones derived from cranberries, and their metabolites could exert anti-inflammatory effects by modulating host microRNAs. Our review first describes the chemical structure of cranberry PACs and a pathway for how they are biotransformed by the gut microbiota. We then provide a brief overview of the benefits of microbial metabolites of cranberry in the intestinal tract, at homeostasis and in inflammatory conditions. Finally, we discuss the role of microRNAs in intestinal health and in response to cranberry PAC and how they could be used as targets for the maintenance of intestinal homeostasis. Most of this research is pre-clinical and we recognize that conducting clinical trials in this context has been hampered by the lack of reliable biomarkers. Our review discusses the use of miRNA as biomarkers in this context.

Metabolic Syndrome (MetS) is characterized by a group of dysmetabolic conditions, including abdominal obesity, dyslipidemia, glucose intolerance and/or insulin resistance, and hypertension. Generally, MetS is accompanied by an exacerbation of oxidative stress, inflammation, and vascular dysfunction. Increasing evidence suggests that berries and berry bioactives could play a potential role in the prevention and mitigation of the risk factors associated with MetS. The present systematic review summarizes the more recently available evidence deriving from human intervention studies investigating the effect of berries in subjects with at least three out of five MetS parameters. The PubMed, Scopus, and Embase databases were systematically searched from January 2010 until December 2022. A total of 17 human intervention trials met the inclusion criteria. Most of them were focused on blueberry (n = 6), cranberry (n = 3), and chokeberry (n = 3), while very few or none were available for the other berries. If considering MetS features, the main positive effects were related to lipid profile (low and high-density lipoproteins, cholesterol, and triglycerides) following blueberries and chokeberries, while conflicting results were documented for anthropometric parameters, blood pressure, and fasting blood glucose levels. Other markers analyzed within the studies included vascular function, oxidative stress, and inflammation. Here, the main positive effects were related to inflammation with a reduction in interleukin 6 and tumor necrosis factor-alpha following the intake of different berries. In conclusion, although limited, the evidence seems to support a potential role for berries in the modulation of lipid profile and inflammation in subjects with MetS. Furthermore, high-quality intervention trials are mandatory to demonstrate the role of berries in reducing risk factors for MetS and related conditions. In the future, such a demonstration could bring the adoption of berries as a potential dietary strategy to prevent/counteract MetS and related risk factors. [ABSTRACT FROM AUTHOR]

The European cranberry (Vaccinium oxycoccus L., syn. Oxycoccus palustris Pers.) has a wide geographical distribution in natural bogs of Europe, Asia, and North America. The American cranberry (Vaccinium macrocarpon Aiton, syn. Oxycoccus macrocarpos (Aiton) Pursh) is more easily cultivated in the northern regions of the world and is therefore an available source of bioactive compounds. They are both rich in polyphenolic compounds (i.e., flavonoids, anthocyanins, and phenolic acids), which have significant antioxidant and antiimmflamatory properties. The cranberry fruits and their preparations represent important natural preservatives used against bacterial and fungal pathogens. Heritage related to its usage refers to the cranberry as a food plant and multiuse ethnomedical remedy. The results of the modern phytochemical and pharmaceutical research suggest using cranberry against urinary tract infections and as a preventive or curing plant against many other diseases. Today there are many new opportunities to draw attention to this plant, including cranberry tourism. In food and pharmaceutical industry the fruits are used most often, but leaves are also rich in biologically active substances, which can be sources for creating new medicines. [ABSTRACT FROM AUTHOR]
