Aims: This study aimed to improve malnutrition in mice and elderlies with a new dairy/buriti oral dietary supplement. Background: Malnutrition is a prevalent problem in the elderly; therefore, oral dietary supplementation is an important strategy to reduce the incidence of this health problem. Objective: The present study evaluated the effects of a low-cost food supplement, made from by-products of the dairy and fruit industry in the Brazilian Cerrado (Buriti), on the nutritional status and the recovery of the metabolic profile of malnourished animals and elderly women. Methods: In the pre-clinical phase, Swiss mice were divided into six groups and subjected to malnutrition and renutrition. The clinical phase was carried out with 25 elderly women residing at a long-term institution, aged ≥ 65 years and with malnutrition or risk of malnutrition. Results: The analyzes showed improvements in anthropometric parameters and an increase in serum albumin levels, in addition to lipid profile improvement in the preclinical phase and an increase in the red blood cells and hemoglobin in the clinical phase. Conclusion: The supplement based on buriti was able to reverse malnutrition promoting improvements in anthropometric and biochemical parameters.

The urban demographic in most developing countries often depend on fossilized fuel generators to meet the electricity supply gap from the national grid. Due to health and environmental concerns with fossilized fuel, local renewable energy resources offer a tentative replacement but often involve high initial upfront costs for their deployment. This work addresses the initial cost barrier issue with renewable energy deployment by focusing on Nigeria as a case study. More specifically, this work proposes a Solar Nano grid concept as an alternative to fossilized generators. The proposed Solar Nano grid concept presents the flexibility to deploy PV systems based on budgetary constraints and the option of upgrading the system (adding newer units to existing ones) in the future. While adding new units to old ones gives rise to compatibility and aging issues in the PV systems, simulation studies show that it is possible to eliminate such concerns by applying a set of design protocols and principles in the proposed Solar Nano grid. An assembled lab-scale Solar Nano grid system validated the simulation findings. With the validated model, this work puts forth possible strategy for reducing the upfront cost of PV system deployment to about 10% of the initial value.

Integrated bioprocess strategies may facilitate ethanol production from both C6 and C5 fractions of lignocellulosic feedstocks. We propose a new process concept, SSICF, where sugarcane bagasse is hydrolyzed simultaneously with xylose isomerization and the co-fermentation of C6 and C5 sugars. A commercial cocktail was supplemented with our multi-enzymatic system composed of three recombinant enzymes immobilized in Feroxyhyte magnetic nanoparticles: β-glucosidase, β-xylosidase and xylose isomerase. SSICF was performed using non-GMO Saccharomyces at pH 6.0 and 35 °C for 72 h in a synthetic medium containing cellobiose and xylose, and another medium containing pretreated sugarcane bagasse (PSB). The results of ethanol global yields in SSICF were 77.67% and 73.24% for the synthetic medium and PSB, respectively. In a nutshell, this is the first report of a successful proof-of-concept of SSICF with four rounds of enzyme recycling and a non-GMO yeast, an innovative process with high potential for industrial use.

Background: Obesity is a serious health problem that dysregulate Renin-Angiotensin System (RAS) and intestinal microbiota. Objective: The present study aimed to evaluate the Angiotensin-(1-7) [ANG-(1-7)] oral formulation effects on obese mice intestinal microbiota. Methods: Mice were divided into four groups: obese and non-obese treated with ANG-(1-7) and obese and non-obese without ANG-(1-7) during four weeks. Results: We observed a significant decrease in the fasting plasma glucose, total cholesterol, triglycerides, and Low-density lipoprotein levels and increased High-density lipoprotein in animals treated with ANG-(1-7). The histological analysis showed intestinal villi height reduction in mice treated with ANG-(1-7). Additionally, increased Bacteroidetes and decreased Firmicutes (increased Bacteroidetes/ Firmicutes ratio) and Enterobacter cloacae populations were observed in the High-Fat Diet + ANG-(1-7) group. Receptor toll-like 4 (TLR4) intestinal mRNA expression was reduced in the HFD+ANG-(1-7) group. Finally, the intestinal expression of the neutral amino acid transporter (B0AT1) was increased in animals treated with ANG-(1-7), indicating a possible mechanism associated with tryptophan uptake. Conclusion: The results of the present study suggest for the first time an interaction between oral ANG-(1-7) and intestinal microbiota modulation.

Background:: The microbiome is now known for its important role in whole-body homeostasis. A dysbiosis of the normal microbiota is correlated with metabolic disorders. In this sense, the search for compounds able to modulate the microbiome is needed. Resveratrol, a natural compound found in grapes seems to be a promising candidate. Objective:: In this study, our motivation was to evaluate the effects of the association between Resveratrol and Lactococcus lactis, a probiotic, on the composition of the gastrointestinal microbiota and body weight of mice. Methods:: Twenty female mice were divided into 4 groups: (1) standard diet, (2) standard diet plus Lactococcus lactis, (3) standard diet plus resveratrol, and (4) standard diet plus Lactococcus lactis and resveratrol. At the end of the treatment period, samples of blood, mucus, stomach, and small and large intestines were collected for analysis. Total levels of Immunoglobulin A and Immunoglobulin E, Lac+ and Lac- bacteria and Lactobacillus were measured. Results:: The main results indicate that the association between resveratrol and probiotics was able to decrease mice body weight, as compared to the other groups, in addition to decrease the number of Lac- bacteria and increasing the number of Lac+ bacteria. The levels of secretory IgA were also decreased, compared to the animals treated with only probiotics or resveratrol. Conclusion:: We observed potential synergism between Resveratrol and Lactococcus lactis mainly in modulating the stomach and intestinal microbiota.

Acosmium dasycarpum (Vog.) Yakovlev, is a Brazilian medicinal plant, belonging to the Fabaceae family known as "Unha D'anta", exclusively found in the Cerrado (Brazilian Savanna) region, and has already shown tranquilizing, hypotensive, antineoplastic and antiseptic activities reported by traditional medicine and scientific evidences. Considering that overweight and obesity are an increasing worldwide health problem, the present study aimed to investigate the anti-obesity effect of bark powder and the dichloromethane extract of A. dasycarpum compared to the most abundant bioactive component (lupeol) using an obese mice model induced by a high-fat diet (HFD). The extracts derived from root bark of A. dasycarpum were characterized (phytochemical screening and GC–MS analysis) and their biological effects tested. After obesity inducement, Swiss male mice were treated with bark root powder or dichloromethane extract or lupeol (all treatments with 10 mg/1000 g/body weight dose) during 14 days. Oral glucose tolerance, insulin sensitivity, lipid profile, histology, ultrasound imaging and adipogenic genes expression were evaluated. The main results showed that A. dasycarpum root bark powder and dichloromethane extract reduced body weight and adiposity as evidenced by histology and ultrasound imaging. We also verified an improved glycemic and lipid profiles by reducing triglycerides, LDL and increasing HDL. The A. dasycarpum treatment suppressed the expression of CCAAT/enhancer-binding protein (C/EBPα), fatty acid translocase (FAT), and stearoyl coenzyme A desaturase-1 (SCD-1) adipogenic genes when compared to the obese control group. In conclusion, A. dasycarpum root bark showed a potential to be an accessible adjuvant treatment for obesity.

General Earth and Planetary Sciences ,General Environmental Science - Abstract
Background Telmisartan is a non-peptide angiotensin II receptor antagonist which acts by ACE/AngII/AT1 axis blockade (ARB). In the last years increasing evidence of its metabolic benefits pointed out this drug as the most promising ARB for nonalcoholic fatty liver disease (NAFLD) treatment. The aim of the present study was to investigate the Telmisartan effect on treating NAFLD in mice fed with a high-fat diet evaluating liver gene modulation. Twenty-four male mice were divided into four groups and fed for 60 days with a standard diet (ST), standard diet plus TEL (ST+TEL 5 mg/kg/day by gavage for 4 weeks), high-fat diet (HFD), or high-fat diet plus TEL (HFD+TEL 5 mg/kg/day by gavage for 4 weeks). Body weight, lipid profile, insulin, alanine transaminase, and aspartate aminotransferase were evaluated. Liver histology was analyzed. US imaging was performed to access liver dimension and echogenicity and also epididymal fat pad thickness. The expression of proinflammatory resistin/TRL4/MYD88 pathway was analyzed. Results The main findings showed that TEL reduced the resistin, TRL4, and Myd88 liver expression in the HFD + TEL group when compared to the obese control group (HFD). Decreased hepatic steatosis in the HFD + TEL group demonstrated by US measurements of the liver longitudinal axis and echogenicity were observed. In addition, TEL reduced epididymal adipose pad thickness, body weight, transaminases, and improved glucose tolerance test and HDL cholesterol. Conclusions We observed that Telmisartan treatment improved metabolism, decreasing NAFLD. Graphical Abstract Telmisartan improves metabolic and lipid profile and liver steatosis of obese mice

Toxicology - Abstract
This study investigated the antineoplastic effects of crotoxin isolated from snake venom of the South American Crotalus durissus terrificus in oral cancer cell lines and in an animal model of chemically induced oral cancer. We analyzed cell viability and death, clonogenic formation, DNA fragmentation, migration assay, and gene expression of MMP2, MMP9, COL1A1, and CASP3. In the animal model, after induction of oral cancer by 4-nitroquinoline-1-oxide carcinogen, mice were treated with crotoxin to investigate its effects on tumor development in tongue and oral mucosa. Crotoxin inhibited cell proliferation, viability, colony formation, and migration, favoring cell death. Furthermore, crotoxin increased caspase-3 expression, decreased Ki-67 protein and mRNA expression of MMP2, MMP9, and COL1A1. Mice treated with crotoxin at 10 μg/kg did not alter biochemical parameters total cholesterol, very-low-density lipoprotein, high-density lipoprotein, liver transaminases, glycemia, creatinine, and urea. Crotoxin treatment significantly reduced the frequency of oral squamous cell carcinoma lesions by 50%. Thus, this study highlights crotoxin as a promising chemotherapeutic substance, considering its effects on controlling the neoplastic cell population, reducing cell migration, and inhibiting tumor development. Clinical studies are necessary to understand better the impact of crotoxin as a potential adjuvant therapeutic agent for oral cancer patients.

Background and Aim: Broiler meat is susceptible to lipid oxidation due to its high content of unsaturated fatty acids, especially when stored for a long time. Concerning with that problem, we can add natural compounds to the animal feed, as the plant essential oils, which have antioxidant, antimicrobial, and antifungal activities. The objective of this study was to evaluate the antioxidant activity, fatty acid profile, and chemical composition of the meat of broilers fed with diets containing different essential oil, including lemongrass (Cymbopogon flexuosus) and pedestrian tea (Lippia aff. rotundifolia). Materials and Methods: The experimental design used was a 4×4 factorial scheme (storage time×diets), and each treatment was repeated thrice. The treatments were applied as negative control (without antimicrobial); positive control (ration supplemented with 10 ppm of enramycin and 42 ppm of salinomycin), lemongrass (ration with 120 mg of essential oil of lemongrass for each kilogram of live weight of the animals), and pedestrian tea (ration with 120 mg of essential oil of pedestrian tea for each kilogram of live weight of the animals). Storage was performed after slaughter and evaluated monthly for 4 months. Results: The inclusion of lemongrass oil and pedestrian tea in the broiler diet did not change the ether extract content of the meat sample obtained from thigh and drumstick. The storage time promotes an increase in the moisture loss of the meat from the 2nd month in all treatments. There was an interaction between the additive and storage time for moisture loss. In the 2nd month of storage, the meat from broilers fed the antibiotic-containing feed had a lower moisture loss than those from broilers in the other treatment groups. The fatty acid profile did not differ statistically between the different treatment groups. The inclusion of additives in the food dropped the lipid oxidation at the 2nd month of storage. From the 3rd month, however, only the essential oils showed antioxidant effect. Conclusion: Antioxidant activity was positive for treatments that included essential oils. The lemongrass oil and pedestrian tea can be used as antioxidant additives in broiler diets to improve the oxidative stability of thigh-drumstick meat during storage. The results of the study suggest a good prospective for further research with profitability of usage essentials oils examined, for their economical application as feed components in broiler nutrition.

Background Head and neck squamous cell carcinoma (HNSC) etiopathogenesis remains unclear, and the biological changes with the activation of heat shock proteins (HSPs) and prion protein (PRNP) promoted by hypoxia in HNSC are undetermined. Objective This study investigates hypoxia's effect in lymph node metastasis by PRNP expression changes and its main partners. Methods The study combined a theoretical/cell culture study with a case-control study. First, bioinformatics and cell culture were performed. A case-control study was performed in a second step by comparing HNSC patients with and without lymph node metastasis. Analyses The Cancer Genome Atlas (TCGA) data source validate the theory in the global population study. Results Bioinformatics analysis suggests that hypoxia-inducible factor-1α (HIF1A) is associated with HSPA4, HSP90AA1, and PRNP expression. TCGA data validate the hypothesis that higher HSP90AA1, HSPA4, and PRNP are related to metastases and low survival. Herein, the cell study demonstrated that muted PRNP did not respond to hypoxia. Conclusions Our results collectively provide the first evidence that PRNP promotes HNSC lymph node metastasis progression through the upregulation of HSPA4, HSP90AA1, and HIF1A. Our findings may provide a molecular basis for the promoting Role of PRNP in HNSC progression.

Research and Theory - Abstract
Background Preeclampsia (PE) is a multifunctional and multisystem disorder. Several factors favor the development of PE, including obesity. Cytokines are also expressed in the placenta, predisposing to local alterations that favor the development of distinct pathological processes, including PE. This study aimed to evaluate the apelin and visfatin mRNA expression in the placental tissue of women with preeclampsia and overweight/obesity and correlates with maternal and fetal variables. Methods A cross-sectional analytical study was performed with 60 pregnant women and their newborns. Clinical, anthropometric, and laboratory variables were collected. Placental tissue samples were obtained, and the apelin and visfatin mRNA expression levels were assessed by qRT-PCR. Results The main findings evidenced lower levels of apelin expression in overweight/obese women, accompanied by a negative correlation with BMI and pre-pregnancy weight; a higher expression of apelin was also observed in women with late PE and no personal history of PE. For visfatin levels, higher expression levels were observed in women with late PE and term delivery. Furthermore, a positive correlation was observed between visfatin levels and fetal anthropometric parameters, such as weight, length, and head circumference. Conclusion Apelin levels were less expressed in overweight/obese women. Apelin and visfatin levels were correlated/associated with maternal-fetal variables.

The COVID-19 pandemic has increased the incidence of depression and other mental disorders in the general population, influenced by various individual and contextual factors. Physical activity (PA) interventions offer a promising approach to mitigating the negative mental health effects of the pandemic. This study aims to analyze the association between PA and depressive symptoms. A total of 785 individuals aged 37.4 ± 13.2 years (72.5% female) were evaluated at two different time points: the first between 2018 and 2019, and the second during the COVID-19 pandemic in 2020. Depressive symptoms, demographic, and socioeconomic data were assessed using the Beck Depression Inventory to estimate depressive symptoms. Frequency analysis and binary and multinomial regression were employed for data analysis. The prevalence of mild depressive symptoms increased from 23.1% before the pandemic to 35.1% during the pandemic. Our findings reveal that practicing PA before the pandemic was a protective factor (OR: 0.19; 95% CI: 0.13, 0.30; p < 0.001) against mild depressive symptoms. Additionally, individuals who continued to practice PA during the pandemic had a lower chance of presenting mild (OR: 0.21; 95% CI: 0.15, 0.30) and moderate/severe (OR: 0.15; 95% CI: 0.08, 0.27) symptoms. Furthermore, our study shows that PA, which was already a protective factor before the pandemic, remained protective during the pandemic, even for those with the highest levels of depression.

Background: Malnutrition induced by dietary restriction produces several metabolic changes that affect body weight, the digestive system, and annex organs, including the liver. Malnutrition generates an inflammatory state and increases oxidative stress. The liver is one of the body vital organs, becoming necessary to analyze the impact of food supplementation on the repair of possible changes that may occur in this organ due to malnutrition. Aims: To evaluate the effects of a low-cost supplementation derived from Buriti and dairy byproducts on liver recovery in malnourished mice, focusing on the expression of oxidative stressrelated genes, as well as biochemical and histological parameters. Methods: Swiss mice were divided into six groups and submitted to two treatment phases: food restriction, for malnutrition onset; and renutrition, with mice being fed with different diets. Results: Our results indicate that dietary supplementation was successful in recovering liver damage caused by malnutrition in animal models. The new supplement has been shown to recover liver damage with similar or superior results compared to the commercial reference supplement on the market. Conclusion: Our work presents a new composition of low cost food supplement based on buriti and dairy by-products, proven to be effective in the malnutrition treatment of malnutrition. The improvements were proven through the recovery of body weight, reduction of inflammation and oxidative stress.

Obesity and metabolic disorders represent a significant global health problem and the gut microbiota plays an important role in modulating systemic homeostasis. Recent evidence shows that microbiota and its signaling pathways may affect the whole metabolism and the Renin-Angiotensin System (RAS), which in turn seems to modify microbiota. The present review aimed to investigate nutritional implications in the mechanistic link between the intestinal microbiome, renin-angiotensin system, and the development of obesity and metabolic syndrome components. A description of metabolic changes was obtained based on relevant scientific literature. The molecular and physiological mechanisms that impact the human microbiome were addressed, including the gut microbiota associated with obesity, diabetes, and hepatic steatosis. The RAS interaction signaling and modulation were analyzed. Strategies including the use of prebiotics, symbiotics, probiotics, and biotechnology may affect the gut microbiota and its impact on human health.

Highlights • Conditioned Fear Stress (CFS) reduced the locomotor activity of the animals. • CFS showed no influence on the progression of neoplasia. • No association between HNSCC staging and BAI scores were observed. • There is no relationship between CFS and oral squamous cell carcinoma., Cancer patients present a higher risk of experiencing anxiety disorders (AD). However, it is not clear if AD might be associated with cancer development. Thus, our study aimed to evaluate if AD might be related to head and neck squamous cell carcinoma (HNSCC) development. The combination of an applied animal basic study and a retrospective diagnostic case and control study in patients was performed. As a result, we obtained that stress reduced the locomotor activity of the animals in the group stress and stress + 4NqO (p < 0.0001). The stress showed no influence on the progression of neoplasia in mice. In the same way, the case group did not present differences in anxiety scores in comparison to control. Moreover, no association between HNSCC staging and anxiety scores was observed. In conclusion, our in vivo findings in humans and animals have shown that there is no relationship between AD and oral squamous cell carcinoma.

Davilla elliptica (Dilleniaceae) is a shrub that occurs naturally in the Brazilian Savannah (Cerrado). This shrub has been widely used in Brazilian folk medicine in tea preparing; infusions; and decoctions from leaves and roots for gastritis, ulcers, and diarrhea treatment. Given the therapeutic potential of this species, the present study provides a comprehensive review on its ethnopharmacological uses, botanical aspects, phytochemistry characterization, and in vivo and in vitro pharmacological studies. The relevant studies on D. elliptica were retrieved from the following scientific databases: Web of Science, Google Scholar, Scopus, SciFinder, PubMed, Scielo, and ScienceDirect. Additional information derived from other literature sources, such as books and Ph.D. and MSc theses, was also considered after a critical review. Ethnopharmacological reports of D. elliptica revealed the use of infusions from roots with tonic and purgative effects, whereas leaves have been used as anti-inflammatory and anti-ulcerative treatments, as well as to treat diarrhea and gastric disorders. Furthermore, fresh leaves have been used in baths to treat swelling. Phytochemical studies have led to the isolation of several compounds, including flavonoids derived from quercetin and myricetin, and tannins, which are known to exhibit relevant pharmacological activities. In vitro assays using crude extracts and/or isolated fractions and chemical constituents from D. elliptica have evidenced antibacterial, cytotoxic activities, while in vivo studies have proven gastroprotective, anti-inflammatory, antihemorrhagic, and antibacterial activities, corroborating ethnomedicinal reports. No relevant side effects has been reported previously, and some studies found a low toxicity and genotoxicity. However, further studies are still needed to ensure the safety of its therapeutic use. Future studies should focused on molecular mechanisms involved in bioactive components’ effects based on both fractions and isolated compounds, creating great opportunities for new investigations.

We have previously demonstrated the presence of Angiotensin (Ang)-(1-7) in rat ovary homogenates and its stimulatory effect on estradiol and progesterone production. The present study was undertaken to identify the cellular localization of Ang-(1-7) and its receptor Mas in the rat ovary in the different phases of the estrous cycle. Ang-(1-7) and Mas were localized by immunohistochemistry and Mas mRNA expression was assessed by RT-PCR. Immunostaining for both Ang-(1-7) and Mas was found in all phases of the estrous cycle, particularly in the thecal and interstitial cells, as well as in regressing corpora lutea. However, granulosa cells were positive only in antral and preovulatory follicles at proestrus and estrus phases. This pattern contrasted with the distribution of the octapeptide Ang II, which was abundant in granulosa but not in theca cells. In addition, the expression of Mas mRNA was demonstrated in all estrous cycle phases. Angiotensin-converting enzyme activity did not vary between estrous cycle phases, whereas prolyl endopeptidase activity was significantly higher in diestrus and neutral endopeptidase activity was significantly higher in metestrus. These data provide the first evidence that new RAS components are dynamically expressed in the ovary across the rat estrous cycle. Further functional studies should clarify the role of Ang-(1-7) signaling through Mas receptor in the regulation of ovarian physiology.

Oral squamous cell carcinoma (OSCC) is one of the most common neoplasms worldwide. The current study aimed to identify potential biomarkers associated with OSCC survival.Differentially expressed genes (DEGs) in atypical OSCC cases were identified using two public datasets: The Cancer Genome Atlas and the Gene Expression Omnibus database. Receiver operating characteristic (ROC) analysis was performed to identify the cutoff, and the candidate DEGs related to survival. Kaplan-Meier and Cox regression analysis using the categorized genes were employed to identify genes that impact the overall survival in OSCC.A total of 263 OSCC samples and 105 healthy tissues were used to identify 295 upregulated and 131 downregulated genes expressed only in non-smokers. ROC analyses identified 25 candidate genes associated with death. Survival analyses demonstrated that the following DEGs, namely CSTA, FGFR2, MMP19, OLR1, PCSK1, RAMP2, and CGB5, are potential OSCC prognostic factors.We found that CSTA, FGFR2, MMP19, OLR1, PCSK1, RAMP2, and CGB5 are associated with a low survival rate in OSCC. However, further studies are needed to validate our findings and facilitate the development of these factors as potential biomarkers for OSCC survival.

Background Lychnophora ericoides Mart. (Asteraceae) is a Brazilian plant commonly used in folk medicine to treat pain and inflammation by topical administration. In recent years, this medicine has begun to be used orally. However, no study concerning its toxicity profile has been reported. Objective The study evaluates the potential toxicity of the ethanolic extract from leaves of the Lychnophora ericoides, through the methods of acute and sub-acute oral administration in mice. Method An acute toxicity study was performed according to the Organization for Economic Cooperation and Development protocol (OECD 423). A single extract dose of 50, 300, and 2000 mg/kg (n=3/group) was administered orally to female Swiss mice. For subacute toxicity, the protocol OECD 407 was followed. Doses of 50, 300, and 500 mg/kg (n=10/group) of the extract were administered daily to Swiss mice of both sexes for 28 days. Abnormal behavior, muscle strength, toxic symptoms, weight, and death were observed when assessing toxicity. Biochemical analysis, hematological analysis, macroscopic examination, and histopathological examination of several organs were conducted at the end of the treatment period. Results In acute and subacute toxicity, the extract did not produce mortality. The acute toxicity study revealed alterations in the behavioral test and histopathological changes in the liver, kidney, lung, and spleen. The subacute oral toxicity test showed changes in hematologic and biochemical parameters. Histopathological examination of liver, kidney, spleen, lung, and heart indicated degenerative characteristics with inflammatory infiltrates focus. Conclusion The study results suggest that oral use of Lychnophora ericoides leaves extract should be performed with caution in low doses in both single and repeated administrations.

Maternal obesity and dietary style in the pregnancy-lactation period may result in long-term effects on the metabolic health of the offspring, thus increasing the risk of diseases, such as obesity, diabetes, and cardiovascular diseases. Curcumin is a natural polyphenolic compound that has beneficial properties on metabolism. Accordingly, this study is intended to evaluate the effects of curcumin supplementation in pregnant and lactating female mice on the body, metabolic and molecular parameters of the offspring fed a hyperglycemic diet. The study was conducted with 24 male mice randomized into three groups: i) control group (SD) originating from dams fed a standard diet; ii) hyperglycemic group (HGD) originating from dams fed a hyperglycemic diet; iii) curcumin group (CUR) originating from dams fed a hyperglycemic diet and supplemented with curcumin in the pregnancy-lactation period. All offspring groups were fed a hyperglycemic diet for 12 weeks. Body and biochemical parameters were measured, as well as the expression of thermogenesis-associated markers in the interscapular brown and inguinal white adipose tissues by the qRT-PCR technique. The results showed less weight gain in the CUR group, with a concomitant reduction in food consumption compared to the HGD group. Biochemical parameters indicated lower levels of total cholesterol, blood glucose, and insulin for the CUR group, in addition to improved glucose tolerance and insulin sensitivity. The molecular evaluation indicated increased mRNA expression levels of UCP1 and PRDM16 in the brown and white adipose tissues. It is concluded that curcumin supplementation in the pregnancy-lactation period in dams with diet-induced obesity may lead to improvements in the offspring's metabolic phenotype, even if they are submitted to an obesogenic environment, possibly via thermogenesis activation.

Differences in the features of aggressiveness of non-melanoma skin cancer (NMSC) subtypes, between basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) are relevant characteristics. Comparing the characteristics between NMSC subtypes might help identify molecules associated with cancer metastasis and invasion. Considering these facts, the current study aimed to identify a molecular target for inhibiting skin cancer metastasis and invasion. Proteomic analysis suggested that heat shock protein 90 kDa, alpha, class B member 1 (HSP90AB1), pentaxin (PTX3), caspase-14 (CASP14), S100, actin-1, and profilin were the primary targets related to metastasis and invasion. However, after a differential expression comparison between BCC and SCC, HSP90AB1 was identified as the best target to repress metastasis and invasion. Based on molecular docking results, gallic acid (GA) was selected to inhibit HSP90AB1. A specific Hsp90ab1 siRNA targeting was designed and compared to GA. Interestingly, GA was more efficient in silencing HSP90AB1 than siRNAhsp90ab1. Hence, our data suggest that HSP90AB1 is a crucial biomarker for identifying invasion and metastasis and that its inhibition may be a viable strategy for treating skin cancer.

Here, we discuss the effects that the dynamics of the hydration layer and other variables, such as the tip radius, have on the availability of imaging regimes in dynamic AFM—including multifrequency AFM. Since small amplitudes are required for high-resolution imaging, we focus on these cases. It is possible to fully immerse a sharp tip under the hydration layer and image with amplitudes similar to or smaller than the height of the hydration layer, i.e., ~1 nm. When mica or HOPG surfaces are only cleaved, molecules adhere to their surfaces, and reaching a thermodynamically stable state for imaging might take hours. During these first hours, different possibilities for imaging emerge and change, implying that these conditions must be considered and reported when imaging.

Neutrophil extracellular traps (NETs) are a recently discovered neutrophil defense mechanism which modulates several inflammatory conditions contributing to metabolic profile alterations. Therefore, the present study aimed to evaluate the production of NETs in obese patients and mice, verifying the possible mechanisms associated with the release of NETs by the adipose tissue.The present study investigated NETs production in human adipose tissue and also showing the neutrophils using intravital microscopy in mouse epididymal adipose tissue. Blood and white adipose tissues were obtained from eutrophic and obese individuals and from mice. Lipid, glycemic and leukocyte profiles were evaluated, as well as the levels of NETs and its markers. Bioinformatics and proteomics analyses were performed and the identified key proteins were measured. The main findings showed that the inflammatory markers interleukin-8 (IL-8), heat shock protein 90 (HSP90) and the E1 heat shock protein family (HSPE1) can be modulated by the NETs levels in obesity. Obesity has also been associated with increased cholesterol, glucose intolerance, ionic calcium and NETs. We also observed an increase in catalase and a decreased superoxide dismutase activity. Bioinformatics and proteomics analyses revealed that IL-8, HSP90 and HSPE1 were associated with obesity, inflammation and NETs release.In conclusion, the present study shows an increase in NETs production during obesity associated with important inflammatory markers in adipose.

Background Davilla elliptica A. St.-Hil, also known as “lixeirinha or sambaibinha” is a shrub belonging to the Dilleniaceae family that occurs naturally in the Brazilian savannah (Cerrado). Research studies have shown evidence of its gastroprotective effect, as well as its benefits as an anti-nociceptive, anti-inflammatory, and antioxidant. However, there are no studies testing the potential effects of D. elliptica on treating metabolic parameters and obesity. Purpose The aim of the present study was to investigate D. elliptica effects on hepatic steatosis induced by a high-fat/high-sugar diet. Methods Animal experimentation was performed using male Swiss mice divided into four groups: ST (standard control), HLHS (obese control), HLHS+EAF (ethyl-acetate fraction), and HLHS+PL (leaf powder). The groups were treated for four weeks with 0.26 mg/kg/body weight. Results The main findings of the present study showed that D. elliptica reduced hepatic lipid deposition, body weight, triglycerides, and total cholesterol levels. Gene expression analysis showed that GPX4 and PPARγ mRNA were significantly suppressed in HLHS + EAF mice livers. Conclusion The present study contributes to elucidating the D. elliptica metabolic role in decreasing GPX4 and PPARγ expression in the HLHS group.

Nowadays the adipose tissue is recognized as one of the most critical endocrine organs releasing many adipokines that regulate metabolism, inflammation and body homeostasis. There are several described adipokines, including the renin-angiotensin system (RAS) components that are especially activated in some diseases with increased production of angiotensin II and several pro-inflammatory hormones. On the other hand, RAS also expresses angiotensin-(1-7), which is now recognized as the main peptide on counteracting Ang II effects. New studies have shown that increased activation of ACE2/Ang-(1-7)/MasR arm can revert and prevent local and systemic dysfunctions improving lipid profile and insulin resistance by modulating insulin actions, and reducing inflammation. In this context, the present review shows the interaction and relevance of Ang-(1-7) effects on regulating adipokines, and as one adipokine itself, modulating body homeostasis, with emphasis on its anti-inflammatory properties, especially in the context of metabolic disorders with focus on obesity and type 2 diabetes mellitus pandemic.

Despite all the development of modern medicine, around 100 compounds derived from natural products were undergoing clinical trials only at the end of 2013. Among these natural substances in clinical trials, we found the resveratrol (RES), a pharmacological multi-target drug. RES analgesic properties have been demonstrated, although the bases of these mechanisms have not been fully elucidated. The aim of this study was to evaluate the involvement of opioid and cannabinoid systems in RES-induced peripheral antinociception. Paw withdrawal method was used and hyperalgesia was induced by carrageenan (200 μg/paw). All drugs were given by intraplantar injection in male Swiss mice (n = 5). RES (100 μg/paw) administered in the right hind paw induced local antinociception that was antagonized by naloxone, non-selective opioid receptor antagonist, and clocinnamox, μOR selective antagonist. Naltrindole and nor-binaltorfimine, selective antagonists for δOR and kOR, respectively, did not reverse RES-induced peripheral antinociception. CB1R antagonist AM251, but not CB2R antagonist AM630, antagonized RES-induced peripheral antinociception. Peripheral antinociception of RES intermediate-dose (50 μg/paw) was increased by: (i) bestatin, inhibitor of endogenous opioid degradation involved-enzymes; (ii) MAFP, inhibitor of anandamide amidase; (iii) JZL184, inhibitor of 2-arachidonoylglycerol degradation involved-enzyme; (iv) VDM11, endocannabinoid reuptake inhibitor. Acute and peripheral administration of RES failed to affect the amount of μOR, CB1R and CB2R. Experimental data suggest that RES induces peripheral antinociception through μOR and CB1R activation by endogenous opioid and endocannabinoid releasing.

Purpose This study aimed to compare the efficacy of Antimicrobial Photodynamic Therapy (aPDT) with 300 µmol/L of methylene blue and 8 µmol/L of curcumin on oral candidiasis patients with HNSCC undergoing treatment. Methods A two-arm, single-blind clinical trial was performed. Following verification for eligibility (n = 447), 108 patients were included in the study. The study consisted of a group that received aPDT with methylene blue (n = 57) and another that received aPDT with curcumin (n = 51). The patients rinsed their mouths with an aqueous solution of 300 µmol/L of methylene blue and 8 µmol/L of curcumin in four sessions, and then the lesion was scraped for the subsequent RT-qPCR. The primary outcome was that no cure was presented for oral candidiasis after treatment. The secondary result was reducing the number of sites affected by oral candidiasis. Results There was no difference in treatment failure evaluated by the necessity of drug prescription or Candida sp DNA quantification. However, clinically the methylene blue protocol reduced the number of infected anatomical sites compared to the curcumin protocol. Conclusion Methylene blue aPDT reduced the number of infected anatomical sites compared to curcumin.

Previous studies have shown that the clove essential oil concentration of 200 mg/kg did not present toxicity and histopathological changes in the liver. Based on the evidence presented in this study, we decided to evaluate in vivo the ability of a previously developed fermented dairy beverage, tested only in vitro, in which the standard chemical preservative, potassium sorbate, was replaced by clove essential oil (2 μl/ml), to be a functional food. To this end, twenty-four male Swiss mice were divided into three groups and submitted insulin sensitivity (IST) and glucose tolerance (GTT) testing, evaluation of physiological and biochemical parameters, histopathological analysis and quantification of the expression of anti-inflammatory and pro-inflammatory cytokines in the liver, after administering daily of the fermented dairy beverage with or without clove essential oil by gavage during 30 days. The group that received the fermented dairy beverage with clove essential oil showed a lower glycemic level in GTT, a higher sensitivity to insulin and a higher glucose decay constant rate (Kitt), with relation to the other groups. In the evaluation of physiological parameters there were no signs of toxicity in the mice during the experimental period. The biochemical parameters, histopathological analysis and expression of anti-inflammatory (IL-10) and pro-inflammatory (IL1β, IL6 e TNFα) cytokines in the liver of the mice, was not significantly affected by the treatment. These results corroborated by bioinformatics analysis demonstrate that the fermented dairy beverage with clove essential oil it can function as a substitute for conventional chemical preservatives and reduce glycemic levels. Estudios previos han demostrado que la concentración de aceite esencial de clavo de 200 mg / kg no presenta toxicidad y cambios histopatológicos en el hígado. Con base en la evidencia encontrada en este estudio, decidimos evaluar in vivo la capacidad de una bebida láctea fermentada desarrollada previamente, probada solo in vitro, en la que el conservante químico estándar, sorbato de potasio, fue reemplazado por aceite esencial de clavo (2 μl / ml), para ser un alimento funcional. Con este fin, veinticuatro ratones suizos se dividieron en tres grupos y se sometieron a pruebas de sensibilidad a la insulina (ITS) y tolerancia a la glucosa (GTT), evaluación de parámetros fisiológicos y bioquímicos, análisis histopatológico y cuantificación de la expresión de antiinflamatorios y pro- citocinas -inflamatorias normativas, después de la administración después de la administración administración de bebida láctea fermentada con o sin aceite esencial de clavo por sonda durante 30 días. El grupo que bebió la leche italiana fermentado con aceite esencial de clavo presentó menor nivel de glucemia en el GTT, mayor sensibilidad a la insulina y mayor tasa constante de desintegración de glucosa (Kitt), en relación a los otros grupos. En la evaluación de los parámetros fisiológicos, no hubo evidencia de toxicidad en los ratones durante el período experimental. Parámetros bioquímicos, análisis histopatológico y expresión de citocinas antiinflamatorias (IL-10) y proinflamatorias (IL1β, IL6 y TNFα) en el hígado de ratones no afectados por el tratamiento. Estos resultados corroborados por análisis bioinformáticos demuestran que la bebida láctea fermentada con aceite esencial de clavo puede actuar como sustituto de los conservantes químicos convencionales y reducir los niveles glucémicos. Estudos anteriores demonstraram que o óleo essencial de cravo da índia na concentração de 200 mg/kg não apresentou toxicidade e alterações histopatológicas no fígado. Com base nas evidências apresentadas neste estudo, decidimos avaliar in vivo a capacidade de uma bebida láctea fermentada desenvolvida e testada anteriormente apenas in vitro, na qual o conservante químico padrão, sorbato de potássio, foi substituído por óleo essencial de cravo (2 μl / ml), para ser um alimento funcional. Para isso, vinte e quatro camundongos Swiss machos foram divididos em três grupos e submetidos a testes de sensibilidade à insulina (TSI) e tolerância à glicose (TTG), avaliação de parâmetros fisiológicos e bioquímicos, análise histopatológica e quantificação da expressão de antiinflamatórios e pró-citocinas inflamatórias no fígado, após administração diária da bebida láctea fermentada com ou sem óleo essencial de cravo da índia por gavagem durante 30 dias. O grupo que recebeu a bebida láctea fermentada com esse óleo essencial apresentou menor nível glicêmico no TTG, maior sensibilidade à insulina e maior taxa constante de decaimento da glicose (Kitt), em relação aos demais grupos. Na avaliação dos parâmetros fisiológicos não houve indícios de toxicidade nos camundongos durante o período experimental. Os parâmetros bioquímicos, a análise histopatológica e a expressão das citocinas antiinflamatórias (IL-10) e pró-inflamatórias (IL1β, IL6 e TNFα) no fígado dos camundongos não foram significativamente afetados pelo tratamento. Esses resultados corroborados por análises de bioinformática demonstram que a bebida láctea fermentada com óleo essencial de cravo da india pode funcionar como substituto dos conservantes químicos convencionais e reduzir os níveis glicêmicos.

Neutrophil extracellular traps (NETs) represent an innate organism defense mechanism characterized by neutrophil release of intracellular material to capture any aggressor agent. Elevated NETs release is associated with increased inflammatory response and related diseases, such as obesity. Chronic physical training is one of the main strategies to treat and prevent obesity. The relationship between physical training and NETs is still under study. The present review, followed by a bioinformatics analysis, demonstrates the meaningful connection between physical exercise, obesity, and NETs. The bioinformatics indicated TNF-α as a leading gene after the ontological analysis followed by positive-interleukin-6 regulation, chemokines, and inflammatory response regulation. The main results pointed to a relevant regulatory effect of physical training on NETs release, indicating physical exercise as a possible therapeutic target on modulating NETs and inflammation.

Background: Malnutrition and accessible high-quality protein food sources are two of the world’s alimentary challenges. Edible insects are nowadays recognized as a possible functional food solution with lower environmental impacts and beneficial health effects. Objective: In this context, the aim of the present study is to evaluate Madagascar cockroach (Gromphadorhina portentosa) flour supplementation effects on a malnourished mice model, considering its effects on metabolism, adiposity, and inflammatory liver profiles. Method: Male Swiss mice are divided into five groups and fed with experimental diets for eight weeks, including a standard diet (ST) ad libitum, AIN93 ad libitum (AIN), insect flour-enriched AIN93 (AIN+IM), AIN-40% feed restriction (AIN-FR), and insect flour-enriched AIN-40% of feed restriction (AIN-FR+IM). The metabolic profiles, adipose tissue, biochemical parameters, and liver IL-6 and IL-10 expression are evaluated. Results: The main findings show a body weight and metabolism improvement followed by an increased recovery of the adipocyte area in the AIN-FR+IM group when compared to the AIN-FR malnourished group. Reduced hepatic IL-6 and increased IL-10 expression are also detected in the AIN-FR+IM group. Conclusion: The results show that insect flour supplementation enhances both body weight and adiposity gain/recovery. The results also show hepatic improvement of inflammatory markers.

The present article reviews the effects of the textile in the wound healing process, as well as the availability of these products in the market. A brief description of applications is given based on the literature obtained from searching the scientific databases, besides the data obtained from secondary sources, like books and congress proceedings. The historical context of the textiles used in wounds, their general characteristics, particularities in the healing process, and incorporation of new technologies are discussed. It was evidenced that the textiles and associated technologies might influence directly or indirectly the stimulation of collagen, cell migration, angiogenesis, and reduction of pro-inflammatory factors and fibroblasts. However, the mechanisms by which the textiles act in the healing process are not well established in the literature. The interaction among textile engineering, biotechnology, medicine, and pharmacology is essential for the improvement and development of new products with better efficiency and accessibility.

Sirtuins (SIRTs) have become important targets in the field of health research as modulators of several metabolic diseases. SIRTs are a family of histone deacetylases regulatory proteins of genetic information with a high degree of conservation among species. Nowadays, several natural products are being investigated as SIRTs modulators. The interest in these new compounds is based on potential health benefits found on caloric restrictive diets, which are mimicked by SIRTs activation, improving mammals’ metabolism and prolonging life expectancy. In the present book chapter we highlight some of the most studied compounds able to activate sirtuins (such as the polyphenols resveratrol and gallic acid) and also different diets and food able to modulate SIRT activity, that is, Mediterranean diet, berberin, green cardamom, and cocoa.

General Earth and Planetary Sciences ,General Environmental Science - Abstract
Este estudo avaliou as competências (acesso, compreensão/avaliação e aplicação) do Letramento em Saúde (LS), utilizando uma nova escala desenvolvida e sua associação com o perfil bioquímico entre pessoas que vivem com diabetes. Para diagnóstico do diabetes, foram utilizados parâmetros bioquímicos. Para validação de constructo da escala, foram utilizadas Análise Fatorial Exploratória (AFE) e Análise Fatorial Confirmatória (AFC). Análises estatísticas estimaram a associação do LS com parâmetros socioeconômicos, bioquímicos, antropométricos e cognitivos. O estudo incluiu 341 pessoas com diabetes. Os resultados mostraram que 91,9% receberam informações relacionadas ao diabetes. AFE demonstrou adequado índice de ajuste (KMO = 0,919) e os itens foram agrupados em 3 fatores: acesso, compreensão/avaliação e aplicação. AFC confirmou o ajuste do modelo (l²/df = 2.09; RMSEA = 0.061). Altos níveis de acesso à informação relacionada ao diabetes implicaram em altos níveis autorrelatados de aplicação. Entretanto, elevado nível de aplicação não foi associado com melhor perfil bioquímico (p < 0,05), incluindo a dosagem de hemoglobina glicada. Modelos de regressão mostraram que características, como cor da pele e cognição, foram associadas com alto nível de LS em todos os domínios. Ademais, uma proporção maior de homens teve maior acesso à informação relacionada ao diabetes, quando comparado às mulheres. Estes resultados demonstram que diferentes fatores devem ser considerados no processo do LS para atingir adequado autocuidado no controle da doença e na prevenção de complicações. Informações de saúde para pessoas que vivem com diabetes devem focar em fatores de risco ou comportamentos que modulam os parâmetros bioquímicos.

CNPq - Conselho Nacional de Desenvolvimento Científico e Tecnológico FAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas Gerais CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior Sirtuins (SIRTs) are a protein family with high preservation degree among evolutionary scale. SIRTs are histone deacetylases regulatory enzymes of genetic material deeply involved in numerous physiological tasks including metabolism, brain function and aging. Mammals sirtuins comprise seven enzymatic components (SIRT1–SIRT7). The highest studied sirtuin is SIRT1, which plays an essential position in the prevention and evolution of neuro-disorders. Resveratrol (3,5,4-trihydroxystylbene) (RSV) is a polyphenol, which belongs to a family compounds identified as stilbenes, predominantly concentrated in grapes and red wine. RSV is the must studied Sirtuin activator and is used as food supplementary compound. Resveratrol exhibits strong antioxidant activity, reducing free radicals, diminishing quinone-reductase-2 activity and exerting positive regulation of several endogenous enzymes. Resveratrol is also able to inhibit pro-inflammatory factors, reducing the stimulation of the nuclear factor kB (NF-kB) and the release of endogenous cytokines. Resveratrol treatment can modulate multiple signaling pathway effectors related to programmed cell death, cell survival, and synaptic plasticity. In this context, the present review looks over news and the role of Sirtuins activation and resveratrol effects on modulating target genes, cognition and neurodegenerative disorders.

Diet macronutrient heterogeneity hinders animal studies' data extrapolation from metabolic disorders to human diseases.The present study aimed to evaluate different fat-diet compositions' effect on inducing lipid/glucose metabolism alterations in mice.Swiss male mice were fed for 12 weeks with five different diets: Standard Diet (ST), American Institute of Nutrition 93 for growth (AIN93G) high-butter/high-sugar (HBHS), high-lard/high-sugar (HLHS), and high-oil/high-sugar diet (soybean oil) (HOHS). Several parameters, such as serum biochemistry, histology, and liver mRNA expression, were accessed.The main findings revealed that the HLHS diet dramatically altered liver metabolism inducing hepatic steatosis and increased total cholesterol, triglycerides, VLDL, increasing liver CCAAT/enhancer binding protein (CEBP-α), Acetyl-CoA carboxylase (ACC) and Catalase (CAT) mRNA expression. Moreover, the HLHS diet increased glucose intolerance and reduced insulin sensitivity.High-fat/high-sugar diets are efficient to induce obesity and metabolic syndrome-associated alterations, and diets enriched with lard and sugar showed more effective results.

Elevated peripheral expression of homocysteine (Hcy) is associated with an increased risk of coronary heart disease and stroke, diabetes, and cancer. It is also associated with cognitive impairment as it has been reported that high levels of Hcy cause cognitive dysfunction and memory deficit. Among several etiological factors that contribute to the pathogenesis of neurodegenerative diseases, including Alzheimer’s disease (AD), Hcy seems to directly contribute to the generation of neurotoxicity factors. This study aims to hypothesize the molecular mechanism by which exercise can reduce the risk of neurological complications promoted by hyperhomocysteinemia (HHcy), and discuss how exercise could reduce the risk of developing AD by using bioinformatics network models. According to the genes network, there are connections between proteins and amino acids associated with Hcy, exercise, and AD. Studies have evidenced that exercise may be one of several processes by which acid nitric availability can be maximized in the human body, which is particularly important in reducing cell loss and tau pathology and, thereby, leading to a reduced risk of complications associated with HHcy and AD.
