Ocular tuberculosis is a challenge in ophthalmic practice because it is extremely difficult to diagnose it. The term ocular tuberculosis indicates any infection by Mycobacterium tuberculosis in, on, or around the eye. It tends to affect all the structures of the eye. Clinical manifestations of ocular tuberculosis depends on the site and severity of its infection. Diagnosis of ocular tuberculosis is entirely clinical, though investigation should be made to confirm the diagnosis. Treatment of ocular tuberculosis is the same as for that of pulmonary tuberculosis.

Objective: The objective of this study was to study the risk factors, management protocols, and the outcome of vulvar cancer cases over a period of 10 years in a tertiary care hospital.Methodology: It is a retrospective cohort study. The hospital records of 41 patients with histologically proven vulvar cancer were studied from the Department of Obstetrics and Gynaecology and the Department of Radiotherapy (RT). The presence of risk factors, stage of disease, treatment modalities used, and disease outcomes in terms of survival were studied. The data collected were analyzed and compared with the published literature.Results: The mean age for the diagnosis of vulvar cancer was 52 years and the peak incidence was seen in the age group of 50-70 years. Incidence was significantly more in multiparous (P = 0.001) and postmenopausal women (P = 0.007). An average of 4.1 cases were seen per year. Nearly, 97.56% of the cases were squamous cell carcinomas. Twenty cases belonged to the early stage of the disease (Stage I and II) whereas 21 cases had advanced disease (Stage III and IV). Nearly, 48.78% of the cases were primarily treated with surgery, 26.83% with RT, 7.3% with chemotherapy, and 17.07% with combined chemoradiation. Seventy-eight percent of the surgically treated cases had a mean survival of 5 years. Mean survival of 1 year was recorded in advanced disease cases. Limitation of the study was poor follow-up after treatment.Conclusion: Incidence of vulvar cancer is significantly high in multiparous and postmenopausal women. Conservative surgical treatment is the best option in the early stage of the disease (Stage I and II) and gives high survival rates whereas advanced disease treated with chemoradiation has a poor survival.

Maconellicoccus hirsutus is a highly polyphagous insect pest, posing a substantial threat to various crop sp., especially in the tropical and sub-tropical regions of the world. While extensive physiological and biological studies have been conducted on this pest, the lack of genetic information has hindered our understanding of the molecular mechanisms underlying its growth, development, and xenobiotic metabolism. The Cytochrome P450 gene, a member of the CYP gene superfamily ubiquitous in living organisms is associated with growth, development, and the metabolism of both endogenous and exogenous substances, contributing to the insect's adaptability in diverse environments. To elucidate the specific role of the CYP450 gene family in M. hirsutus which has remained largely unexplored, a de novo transcriptome assembly of the pink mealybug was constructed. A total of 120 proteins were annotated as CYP450 genes through homology search of the predicted protein sequences across different databases. Phylogenetic studies resulted in categorizing 120 CYP450 genes into four CYP clans. A total of 22 CYP450 families and 30 subfamilies were categorized, with CYP6 forming the dominant family. The study also revealed five genes (Halloween genes) associated with the insect hormone biosynthesis pathway. Further, the expression of ten selected CYP450 genes was studied using qRT-PCR across crawler, nymph, and adult stages, and identified genes that were expressed at specific stages of the insects. Thus, the findings of this study reveal the expression dynamics and possible function of the CYP450 gene family in the growth, development, and adaptive strategies of M. hirsutus which can be further functionally validated., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

The pink or hibiscus mealybug, Maconellicoccus hirsutus, is a serious pest of grapes, jute, and mesta, causing severe yield losses in India and other countries. Chemical control remains the foremost choice for farmers to manage this pest. As insecticides break down over time due to biotic and abiotic factors, insects are exposed to varying levels of these exogenous compounds. Several studies have reported that sublethal doses affect insect physiology, but only a few have examined the changes in gene expression at the molecular level. Therefore, the present study was conducted to elucidate the molecular mechanisms in M. hirsutus exposed to sublethal doses of buprofezin 25 SC. Life table analysis revealed increased fecundity in M. hirsutus exposed to the sublethal dose. A total of 1,744 differentially expressed genes were identified between the buprofezin-treated and untreated samples using transcriptome analysis. These genes were primarily associated with ribosomal proteins, proteases, cuticular proteins, and cytoskeletal structures. Ribosomes and phagosomes were the most highly enriched pathways. Interestingly, most of the DEGs were involved in restoring homeostasis rather than detoxification. To validate our RNA-sequencing results, qRT-PCR validation was performed on ten randomly selected genes. Overall, our findings provide valuable insights into intermittent changes in stress-coping genes, apart from detoxification genes., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

In this study, Calonectria eucalyptorum sp. nov. is described from the blighted leaves of Eucalyptus in India using morphological and multi-locus phylogenetic analyses. The new species belongs to the Calonectria cylindrospora species complex, and its unique microscopic features and DNA sequence information enable clear separation from the 12 currently accepted species in this complex. Conidia of the new taxon are slightly longer than those of its phylogenetic neighbors. Additionally, this species produces central as well as lateral stipe extensions, which is a feature not known for the other members of the C. cylindrospora species complex. Analyses of the combined partial calmodulin, histone, translation elongation factor-1α, and β-tubulin gene regions revealed a distinct phylogenetic position for C. eucalyptorum. Recombination analysis provided additional support for the new species hypothesis. Koch's postulates for the new taxon as a foliar pathogen of Eucalyptus were fulfilled. The discovery of novel and pathogenic Calonectria species is important because it sheds light on species diversity, potential threats, and disease control., (© 2024.

Introduction: Otitis media is defined as inflammation of the middle ear due to any cause that may also involve any contiguous pneumatized portion of the temporal bone. It is also one of the most common diseases of childhood after viral upper respiratory tract infection. As a result of the widespread availability of over-the-counter topical antibiotics and the irrational use of these agents, there is a development of multidrug-resistant bacteria., Aim: The aim of this study was to assess the current bacteriological profile and antimicrobial susceptibility pattern in clinically diagnosed cases of active chronic otitis media (COM) at a tertiary care center in Uttarakhand., Materials and Methods: The proposed observational cross-sectional study was conducted in the Department of Otolaryngology and Head and Neck Surgery and Department of Microbiology of Government Doon Medical College Hospital, Dehradun, over a period of 18 months from August 2022 to January 2024. One hundred and thirty-seven cases of active COM fulfilling the inclusion criteria were recruited in the study. Under strict aseptic conditions, pus samples were collected from the middle ear using two sterile cotton swabs under microscopic examination and sent to the microbiology lab for pathogen identification and isolation. The isolated organisms were subjected to antibiotic susceptibility testing using VITEK-2 as per the latest Clinical and Laboratory Standards Institute (CLSI) guidelines.  Results: In the present study, the most common age group affected by COM was between 18 and 30 years with female predominance. Pseudomonas aeruginosa (33.6%) was the predominantly isolated organism followed by Staphylococcus aureus (17.8%). Considering the antibiotic susceptibility, Pseudomonas aeruginosa was susceptible to piperacillin/tazobactam and meropenem while least sensitive to levofloxacin and ciprofloxacin. Staphylococcus aureus was susceptible to linezolid, daptomycin, and vancomycin. The maximum resistance of Staphylococcus aureus was observed to ciprofloxacin and levofloxacin., Conclusion:  The study of changing clinico-bacteriological profile and antibiotic susceptibility pattern in cases of COM due to variations in the geography and environment of the study population can help to guide appropriate antibiotic treatment and thus prevent the development of multidrug-resistant bacteria., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Eucalyptus spp. are undoubtedly one of the most favored plantation trees globally. Accurately identifying Eucalyptus pathogens is therefore crucial for timely disease prevention and control. Recently, symptoms of a leaf blight disease were observed on Eucalyptus trees in plantations at Jhajjar and Karnal in the state of Haryana, northern India. Asexual morphs resembling the features of the Botryosphaeriaceae were consistently isolated from the symptomatic leaves. Morphological features coupled with DNA sequence analysis confirmed a novel species, which is described and illustrated here as Botryosphaeria eucalypti sp. nov. Conidia of the new taxon are longer and wider than those of its phylogenetic neighbors. A distinct phylogenetic position for the new taxon was established through combined analysis of the internal transcribed spacer (ITS), partial translation elongation factor-1α (tef1) and partial β-tubulin (tub2) regions. Recombination analysis provided additional support for the new species hypothesis. The pathogenicity of the novel species was proved on Eucalyptus leaves, and Koch's postulates were fulfilled. The discovery of new Botryosphaeria species is important because it will help in understanding the species diversity, host range, possible threats and disease control in the long run., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Fruit crops are frequently subjected to biotic and abiotic stresses that can significantly reduce the absorption and translocation of essential elements, ultimately leading to a decrease in crop yield. It is imperative to grow fruits and vegetables in areas prone to drought, salinity, and extreme high, and low temperatures to meet the world's minimum nutrient demand. The use of integrated approaches, including supplementation of beneficial elements like silicon (Si), can enhance plant resilience under various stresses. Silicon is the second most abundant element on the earth crust, following oxygen, which plays a significant role in development and promote plant growth. Extensive efforts have been made to explore the advantages of Si supplementation in fruit crops. The application of Si to plants reinforces the cell wall, providing additional support through enhancing a mechanical and biochemical processes, thereby improving the stress tolerance capacity of crops. In this review, the molecular and physiological mechanisms that explain the beneficial effects of Si supplementation in horticultural crop species have been discussed. The review describes the role of Si and its transporters in mitigation of abiotic stress conditions in horticultural plants., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: We declare that, we have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper and the following financial interests/personal relationships which may be considered as potential competing interests., (Copyright © 2024 Elsevier Masson SAS.

Background: Hereditary pancreatitis (HP) is a chronic and recurrent inflammatory disorder caused by genetic abnormalities, often accompanied by severe symptoms and complications. Conventional treatments offer limited relief but fail to halt disease progression. An Ayurvedic Treatment Protocol has been reported to be effective in treating various types of pancreatitis., Objectives: This observational clinical study is aimed at assessing the efficacy of a year long Ayurvedic treatment protocol (ATP) in mitigating attack frequency and intensity in Hereditary Pancreatitis patients., Materials & Methods: The study enrolled 151 patients across diverse age groups and genders, subjecting them to a comprehensive Ayurvedic treatment protocol at a specialized center. The protocol incorporated Metal-Based Ayurvedic Formulation (MBAF) named Amar, alongside supportive Ayurvedic compounds and dietary adjustments. Patients underwent pre- and post-treatment evaluations involving interviews, medical records, blood tests, radiological imaging, and symptom assessments. Notably, pancreatic enzyme use was discontinued prior to initiating Ayurvedic treatment., Results: Among 151 patients, 88 completed the year long ATP, resulting in significant enhancement of their quality of life. There was a marked 98.7% reduction in emergency hospitalizations and a notable 92.8% decrease in attack frequency (p < 0.0001). Radiological assessments indicated pancreatic health stabilization, while no adverse effects were reported, highlighting the intervention's safety and tolerability., Conclusion: The study furnishes promising evidence supporting the efficacy and safety of ATP, especially the MBAF, in managing Hereditary Pancreatitis. The observed decline in attack frequency, absence of adverse effects, and stabilization of pancreatic health underscore the potential of Ayurvedic medicine. Subsequent research, including randomized controlled trials, is warranted to substantiate these findings and elucidate underlying mechanisms., Competing Interests: Conflict of interest Authors declare no conflicts of competing interest., (Copyright © 2024 The Authors.

Background: Ayurveda, an ancient Indian system of medicine, encapsulates comprehensive principles and formulations for disease prevention and treatment. A herbo-mineral Ayurvedic formulation, IMMBO, comprising Mandoor Bhasma and 18 herbs has shown promising results in treating allergic rhinitis in clinical studies., Objective: This discussed series of experimental studies were conducted to explore the immuno-modulatory potential of IMMBO., Methodology: A series of experimental studies were carried out in immunosuppressed rats to explore the immune-modulatory effects of IMMBO., Results: IMMBO was effective in reinstating neutrophil activation, stimulating cellular and humoral immunity, and counteracting immunosuppression at the molecular level. The modulation of key signalling molecules, including tumour necrosis factor-alpha (TNF-α), interferon-gamma (IFN-γ), interleukin-1 beta (IL-1β), extracellular signal-regulated kinase (ERK), phosphoinositide 3-kinase (PI3K), and nuclear factor-kappa B (NF-κb), showcased the formulation's multifaceted impact. Additionally, its ability to block histamine release suggests potential in controlling allergic states, positioning it as a promising therapeutic candidate for immune-related disorders. However, the precise mode of action remains elusive, warranting further in-depth pharmacological studies., Conclusion: This research substantiates the ancient Ayurvedic wisdom using modern scientific parameters, endorsing IMMBO's potential as an immune-modulatory agent., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Prakash et al.)

Background: The Ganga River System (GRS) is a biodiversity hotspot, its ecological richness is shaped by a complex geological history. In this study, we examined the genetic diversity, spatial connectivity, and population structure of the Asian Silurid catfish, Wallago attu, across seven tributaries of the GRS., Methods and Results: We employed three mitochondrial DNA (mtDNA) regions: cytochrome c oxidase subunit I (COXI), cytochrome b (Cyt b), and control region (CR). Our comprehensive dataset encompassed 2420 bp of mtDNA, derived from 176 W. attu individuals across 19 sampling sites within the seven rivers of GRS. Our findings revealed high gene diversity (Hd:0.99) within W. attu populations. Analysis of Molecular Variance (AMOVA) highlighted that maximum genetic variations were attributed within the populations, and the observed genetic differentiation among the seven populations of W. attu ranged from low to moderate. Network analysis uncovered the presence of three distinct genetic clades, showing no specific association with seven studied rivers. Bayesian skyline plots provided insights into the demographic history of W. attu, suggesting a recent population expansion estimated to have occurred approximately 0.04 million years ago (mya) during the Pleistocene epoch., Conclusions: These results significantly enhance our understanding of the genetic diversity and spatial connectivity of W. attu, serving as a vital foundation for developing informed conservation strategies and the sustainable management of this economically valuable resource within the Ganga River System., (© 2024.

Background: Lower respiratory tract infections (LRTIs) are associated with significant morbidity and mortality in all age groups, especially young children and the elderly population. Various gram-positive and gram-negative organisms such as Streptococcus spp., Pseudomonas spp., and Klebsiella spp. have been implicated as a pathogen in bronchoalveolar lavage (BAL) specimens collected from such patients., Aims and Rationale of the Study: The present study is aimed at assessing the spectrum of the bacterial isolates and determining the antimicrobial resistance obtained from the BAL fluid from admitted patients at various wards and intensive care units (ICUs) of a tertiary care hospital in Dehradun. This will be the stepping stone in our efforts toward becoming a future antimicrobial steward and framing local antibiograms based on such data., Material and Methods: Two hundred BAL specimens were collected from patients admitted to various wards and ICUs of the hospital who were suffering from LRTI. The BAL specimens were subjected to direct microscopy and culture. Identification and susceptibility testing were performed., Results: The most predominant isolates were Pseudomonas aeruginosa (16/39 (41.02%)) followed by Klebsiella pneumoniae (7/39 (17.94%)) and Acinetobacter spp. (6/39 (15.38%)). Sixty-five percentage of Pseudomonas aeruginosa, 71% of Klebsiella pneumoniae, and 83% of Acinetobacter spp. showed intermediate results with colistin., Conclusion: Nonfermenters constitute a significant group of organisms isolated from bronchoalveolar lavage (BAL) specimens in patients with lower respiratory tract infections (LRTIs). Hence, it is extremely important to correctly identify and determine the resistance pattern of such isolates so that appropriate empirical therapy can be initiated for the benefit of the patient., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Journal of Family Medicine and Primary Care.)

Background and Objectives: Despite progress in diagnosing and managing ventilator-associated pneumonia (VAP), ongoing monitoring of ventilator-associated events (VAE) is crucial due to VAP's persistent prominence as the primary cause of Hospital-Acquired Infection (HAI) among Intensive Care unit patients. This study was done to illuminate the prevalence of VAE and antibiogram of bacterial isolates of VAP in a tertiary care hospital of Uttarakhand., Materials and Methods: This cross-sectional study focused on ICU patients. Adult patients ventilated for > 2 days were monitored daily, with VAE data analyzed using Center of Disease Control & Prevention (CDC) criteria. Specimens were sent to the Microbiology Department and cultured on Blood agar and MacConkey agar. Identification and antimicrobial profiles of isolates were determined using Vitek-2 Compact., Results: 1220 ventilated individuals were assessed in total. VAE was diagnosed in 6.4% (78/1220) of the patients, the same later developed ventilator associated condition (VAC), 74 developed the infection-related VAC (IVAC), and 60 developed the possible/probable VAP (PVAP) among the 78 VAE cases. Klebsiella pneumoniae (35%), Acinetobacter baumannii (33%), and Pseudomonas aeruginosa (16%) were the most common isolated organisms. Colistin (57%) was the most effective against Klebsiella pneumoniae, followed by amikacin (28.5%) and trimethoprim+sulfamethoxazole (24%). Pseudomonas aeruginosa was most susceptible to imipenem (70%), meropenem, cefoperazone+sulbactam, and colistin (60%). Acinetobacter baumannii was most susceptible to colistin (85%), tigecycline (65%), and trimethoprim+sulfamethoxazole (25%)., Conclusion: The most common cause of HAI is VAP. The purpose of this study is to determine the importance of starting suitable antibiotics early for prognosis and the difficulty of diagnosing VAP., (Copyright © 2023 The Authors.

The whole world has battled with multiple waves of coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 virus. However, the second wave of COVID-19 had caused a worldwide havoc in terms of disease transmissibility, severity, and mortality. India has been among the worst hit countries during the second wave, which substantially overburdened and overwhelmed the Indian health care system. While secondary infections and co-infections among COVID-19 patients were increasingly being reported, COVID-19-associated mucormycosis (CAM) emerged as a new challenge particularly from India and became a matter of immediate concern. The most common causes attributed to the rise of CAM were undiagnosed/uncontrolled diabetes mellitus, excessive use of corticosteroids, and prolonged hospital stay, all of which create a perfect environment for mucormycosis infection to set in., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Journal of Family Medicine and Primary Care.)

Genetic diversity is the primary source of variability in any crop improvement program, and the diverse germplasm of any crop species represents an important genetic resource for gene or allele mining to meet future needs. Huge genetic and phenotypic diversity is present in the apple gene pool, even though, breeding programs have been mainly focused on a few traits of interests, which have resulted in the reduction of the diversity in the cultivated lines of apple. Therefore, the present study was carried out on 70 diverse apple genotypes with the objective of analyzing the genetic diversity and to identify the genetic loci associated with important fruit quality traits. A total of 140 SSR primers were used to characterize the 70 genotypes of apples, out of which only 88 SSRs were found to be polymorphic. The PIC values varied from 0.03 to 0.75. The value of MI, EMR, and RP varied from 0.03 to 3.5, 0.5 to 5.0, and 1.89 to 6.74, respectively. The dendrogram and structure analysis divided all the genotypes into two main groups. In addition to this, large phenotypic variability was observed for the fruit quality traits under study indicated the suitability of the genotypes for association studies. Altogether 71 novel MTAs were identified for 10 fruit quality traits, of which 15 for fruit length, 15 for fruit diameter, 12 for fruit weight, 2 for total sugar, 2 for TSS, 4 for reducing sugar, 5 for non-reducing sugar, 5 for fruit firmness, 5 for fruit acidity and 6 for anthocyanin, respectively. Consistent with the physicochemical evaluation of traits, there was a significant correlation coefficient among different fruit quality characters, and many common markers were found to be associated with these traits (fruit diameter, length, TSS, total sugar, acidity and anthocyanin, respectively) by using the different modeling techniques (GLM, MLM). The inferred genetic structure, diversity pattern and the identified MTAs will be serving as resourceful grounds for better predictions and understanding of apple genome towards efficient conservation and utilization of apple germplasm for facilitating genetic improvement of fruit quality traits. Furthermore, these findings also suggested that association mapping could be a viable alternative to the conventional QTL mapping approach in apple., Supplementary Information: The online version contains supplementary material available at 10.1007/s12298-023-01382-w., Competing Interests: Conflict of interestThe authors declare that they have no competing interests., (© Prof. H.S.

Background: Allergic rhinitis is largely treated by using antihistamines and nasal sprays, either alone or in combination. However, these measures ease out the symptoms but do not address causative factors, and have their share of side effects and limitations. An Ayurvedic herbo-mineral formulation, IMMBO, has been reported to be effective in treating allergic rhinitis., Objective: The present study was carried out to evaluate the efficacy, safety, and tolerability of the Ayurvedic herbo-mineral formulation in comparison with a fixed-dose combination of levocetirizine and montelukast., Method: This was a randomized, comparative, clinical study carried out on 250 patients at a medical college in India. The patients were enrolled according to the eligibility criteria of the study and randomized into two groups, to receive either Ayurvedic herbo-mineral formulation, IMMBO, or a combination of levocetirizine and montelukast for 28 days. Total nasal symptom score (TNSS) and Immunoglobulin E (IgE) were calculated for evaluation of efficacy parameters.  Result: At the end of therapy both IMMBO and levocetirizine and montelukast combination showed significant improvement in TNSS in both treated population and per protocol population. The IMMBO group had a statistically higher reduction in TNSSs compared to the levocetirizine + montelukast group (-5.70 vs. -3.31; p<0.01). There was a statistically significant difference in the reduction of IgE levels between the groups (-351.54 vs. -208.79; p<0.05).  Conclusion: The findings of this study establish prima facie evidence about the efficacy and safety of Ayurvedic formulation. However, the said Ayurvedic formulation needs to be further developed scientifically., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Prakash et al.)

Objective: This study aimed to reveal characteristic condylar movements in patients with jaw deformities., Study Design: Thirty patients with jaw deformities before surgery were enrolled and instructed to chew a cookie during 4-dimensional computed tomography (4DCT). The distance between the most anterior and posterior positions of the bilateral condyles on 4DCT images was measured and compared among patients with different skeletal classes. Correlations between the condylar protrusion and cephalometric values were also determined., Results: The distances of condylar protrusion during mastication were significantly greater in the skeletal class II group than in the skeletal class III group ( P =0.0002). Significant correlations were found between the distances of condylar protrusion during mastication and the sella-nasion-B point angle ( r =-0.442, P =0.015), A point-nasion-B point angle ( r =0.516, P =0.004), sella-nasion plane to ramus plane angle ( r =0.464, P =0.01), sella-nasion plane to occlusal plane angle ( r =0.367, P =0.047), and condylion-gonion length ( r =-0.366, P =0.048)., Conclusion: Motion analysis with 4DCT images revealed that condylar movement in patients with retrognathism was larger than in patients with mandibular prognathism. Skeletal structure was therefore correlated with condylar movement during mastication., Competing Interests: The authors report no conflicts of interest., (Copyright © 2023 by Mutaz B. Habal, MD.)

Osteomyelitis, an infection related to bone and bone marrow, is very diverse in its pathophysiology and clinical presentation; hence, it is considered one of the most difficult-to-treat infections. The present study is aimed at assessing the microbiological profile of osteomyelitis and related antimicrobial susceptibility patterns in patients attending a tertiary care center in Uttarakhand, India, over a period of one year (January to December 2019). In aerobic culture, 58/105 (55.2%) bacterial isolates were detected. In addition,  Staphylococcus aureus  was the most common isolate, and amongst Gram-negative bacilli, most isolates that grew on culture were Escherichia coli  (22.4%). Out of 21  S. aureus  isolates, methicillin resistance was detected in nine [9/21 (42%)] cases, which is a matter of concern. Hence, proper training and application of antimicrobial stewardship are the need of the hour so that clinicians can initiate targeted therapy as early as possible., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Raina et al.)

The present study was conducted to understand the key ecological and biological questions of conservation importance in Drepanostachyum falcatum which aimed to map potential distribution in the western Himalayas and decipher spatial genetic structure. Eco-distribution maps were generated through ecological niche modelling using the Maximum Entropy (MaxEnt) algorithm implemented with 228 geocoordinates of species presence and 12 bioclimatic variables. Concomitantly, 26 natural populations in the western Himalayas were genetically analysed using ten genomic sequence-tagged microsatellite (STMS) markers. Model-derived distribution was adequately supported with appropriate statistical measures, such as area under the 'receiver operating characteristics (ROC)' curve (AUC; 0.917 ± 0.034)", Kappa (K; 0.418), normalized mutual information (NMI; 0.673) and true skill statistic (TSS; 0.715). Further, Jackknife test and response curves showed that the precipitation (pre- and post-monsoon) and temperature (average throughout the year and pre-monsoon) maximize the probabilistic distribution of D. falcatum. We recorded a wide and abundant (4096.86 km 2 ) distribution of D. falcatum in the western Himalayas with maximum occurrence at 1500 to 2500 m asl. Furthermore, marker analysis exemplified high gene diversity with low genetic differentiation in D. falcatum. Relatively, the populations of Uttarakhand are more genetically diverse than Himachal Pradesh, whereas within the Uttarakhand, the Garhwal region captured a higher allelic diversity than Kumaon. Clustering and structure analysis indicated two major gene pools, where genetic admixing appeared to be controlled by long-distance gene flow, horizontal geographical distance, aspect, and precipitation. Both the species distribution map and population genetic structure derived herein may serve as valuable resources for conservation and management of Himalayan hill bamboos., (© 2023.

Significance Statement: CKD is accompanied by abnormal inflammation, which contributes to progressive loss of functional renal tissue and accelerated cardiovascular disease. Although studies have documented that dysregulation of monocyte maturation and function is associated with CKD and its complications, it is not well characterized. This study reveals that a distinctive human monocyte subtype with high propensity for releasing proinflammatory mediators and activating endothelial cells is increased in adults with CKD compared with adults with high cardiovascular risk and normal kidney function. It also demonstrates that human monocyte adhesion to endothelial layers and responses to specific inflammatory migration signals are enhanced in CKD. These findings offer insights into the mechanisms of CKD-associated intravascular and localized inflammation and may suggest potential targets for therapeutic interventions., Background: Cardiovascular disease (CVD) in patients with CKD is associated with increased circulating intermediate monocytes (IMs). Dysregulation of monocyte maturation and function is associated with CKD and its complications, but it is incompletely characterized., Methods: To explore monocyte repertoire abnormalities in CKD, we studied properties of monocyte subpopulations, including IM subpopulations distinguished by HLA-DR expression level, in individuals with or without CKD. Using flow cytometry, we profiled monocyte populations in blood samples from adults with CKD, healthy volunteers (HVs), and patient controls (PCs) with high CVD risk. Monocyte subpopulations were also derived from single-cell RNA-sequencing profiles of paired blood and biopsy samples from kidney transplant recipients. We quantified intracellular cytokine production, migration, and endothelial adhesion in ex vivo assays of PBMCs., Results: Of four predefined blood monocyte subpopulations, only HLA-DR hi IMs were increased in individuals with CKD compared with HVs and PCs. In HVs and patients with CKD, LPS-stimulated HLA-DR hi IMs isolated from blood produced higher amounts of TNF and IL-1 β than other monocyte populations. Single-cell analysis revealed four monocyte clusters common to blood and kidneys, including an HLA-DR hi IM-like cluster that was enriched in kidneys versus blood. Migration toward CCL5 and CX3CL1 and adhesion to primary endothelial cell layers were increased in monocyte subpopulations in individuals with CKD compared with HVs. Monocyte adhesion to endothelial cells was partly dependent on CX3CR1/CX3CL1 interaction., Conclusions: CKD is associated with an increased number of a distinctive proinflammatory IM subpopulation and abnormalities of monocyte migration and endothelial adhesion. Dysregulated monocyte maturation and function may represent targetable factors contributing to accelerated CVD in CKD., (Copyright © 2023 by the American Society of Nephrology.)

Background and Objectives: In healthcare settings, hospital water and water-related devices can act as a reservoir for waterborne infections. Potable water, sinks, faucet aerators, showers, tub immersion, toilets, dialysis water, water baths, eyewash stations, and dental-unit water stations have all been linked to nosocomial outbreaks. This study aimed to determine the microbial profile and pattern of antibiotic resistance in the water supply of a tertiary care hospital in Uttarakhand., Materials and Methods: This is a 1-year prospective study which was carried out by the Department of Microbiology and Immunology at Sri Mahant Indersh Hospital (SMIH), Dehradun. A total of 154 water samples were collected from the AC outlets, ventilators in the Intensive care unit (ICUs), Operation theatre (OTs), and High dependency unit (HDUs), scrub stations, pantry, and blood bank, patient's bathroom, private ward, septic ward, labour room, transplant unit, laboratory, scope rinse water, the dialysis unit and tank throughout the hospital, including tap water (pre and post flush [25%]), tap swabs (24%), drinking water (9%), AC outlets (13%), and other areas (3%)., Results: 30 of the 154 (19.5%) water samples tested were culture-positive. The most contaminated water samples were tap swabs (27%, n = 8/30). A total of nine organisms were isolated, of which the most predominant was Pseudomonas aeruginosa (40%; 12/30), followed by Legionella pneumophila (13%; 4/30), Acinetobacter baumanii (10%; 3/30), Klebsiella pneumoniae (10%; 3/30), Escherichia coli (7%; 2/30), Enterococcus faecalis (7%; 2/30), Aspergillus flavus (7%; 2/30), Stenotrophomonas (3%; 1/30), and Fusarium spp. (3%; 1/30). Gram-negative bacilli and non-lactose fermenting (GNB and NLF) showed a high rate of contamination, 53.3% (n = 16/30). P. aeruginosa showed resistance to gentamicin and amikacin (42%), imipenem (50%), levofloxacin (58%), and colistin (25%), while Acinetobacter baumanii showed resistance to gentamicin and amikacin (67%), minocycline (63%), and levofloxacin, imipenem and colistin (33%)., Conclusion: The study's findings show that a variety of microorganisms are contaminating hospital water supplies and can be a source of hospital-acquired infections. A suitable and robust surveillance program for hospital water supplies, as well as strict adherence to infection control practices, is strongly advised., (Copyright © 2023 The Authors.

Globally, industrial farming endangers crucial ecological mechanisms upon which food production relies, while 815 million people are undernourished and a significant number are malnourished. Zero Hunger aims to concurrently solve global ecological sustainability and food security concerns. Recent breakthroughs in molecular tools and approaches have allowed scientists to detect and comprehend the nature and structure of agro-biodiversity at the molecular and genetic levels, providing us an advantage over traditional methods of crop breeding. These bioinformatics techniques let us optimize our target plants for our soil-less medium and vice versa. Most of the soil-borne and seed-borne diseases are the outcomes of non-treated seed and growth media, which are important factors in low productivity. The farmers do not consider these issues, thereby facing problems growing healthy crops and suffering economic losses. This study is going to help the farmers increase their eco-friendly, chemical residue-free, quality yield of crops and their economic returns. The present invention discloses a synergistic soil-less medium that consists of only four ingredients mixed in optimal ratios by weight: vermicompost (70-80%), vermiculite (10-15%), coco peat (10-15%), and Rhizobium (0-1%). The medium exhibits better physical and chemical characteristics than existing conventional media. The vermiculite to coco peat ratio is reduced, while the vermicompost ratio is increased, with the goals of lowering toxicity, increasing plant and water holding capacity, avoiding drying of the media, and conserving water. The medium provides balanced nutrition and proper ventilation for seed germination and the growth of seedlings. Rhizobium is also used to treat the plastic bags and seeds. The results clearly show that the current synergistic soil-less environment is best for complete plant growth. Securing genetic advantages via sexual recombination, induced random mutations, and transgenic techniques have been essential for the development of improved agricultural varieties. The recent availability of targeted genome-editing technology provides a new path for integrating beneficial genetic modifications into the most significant agricultural species on the planet. Clustered regularly interspaced short palindromic repeats and associated protein 9 (CRISPR/Cas9) has evolved into a potent genome-editing tool for imparting genetic modifications to crop species. In addition, the integration of analytical methods like population genomics, phylogenomics, and metagenomics addresses conservation problems, while whole genome sequencing has opened up a new dimension for explaining the genome architecture and its interactions with other species. The in silico genomic and proteomic investigation was also conducted to forecast future investigations for the growth of French beans on a synergistic soil-less medium with the purpose of studying how a blend of vermicompost, vermiculite, cocopeat, and Rhizobium secrete metal ions, and other chemical compounds into the soil-less medium and affect the development of our target plant as well as several other plants. This interaction was studied using functional and conserved region analysis, phylogenetic analysis, and docking tools., (© 2023.

Background: Lesion gaps assessed by late-gadolinium enhancement magnetic resonance imaging (LGE-MRI) are associated with the atrial fibrillation (AF) recurrence after pulmonary vein isolation. Animal studies have demonstrated that the catheter-contact force (CF), stability, and orientation are strongly associated with lesion formation. However, the impact of those procedural factors on the lesion characteristics associated with AF recurrence has not been well discussed., Methods: A total of 30 patients with paroxysmal AF who underwent catheter ablation were retrospectively enrolled. Radiofrequency (RF) applications were performed with 35 W for 30 s in a point-by-point fashion under esophageal temperature monitoring. The inter-lesion distance was 4 mm. The lesions were visualized by LGE-MRI 3 months postprocedure and assessed by the LGE volume (ml), gap number (GN), and average gap length (AGL [mm]). The gaps were defined as nonenhancement sites of >4 mm. The procedural factors including the catheter-CF, stability, and orientation were calculated on the NavX system., Results: Six (20%) of 30 patients had AF recurrences 12 months postablation. A univariate analysis demonstrated that the AGL was associated with AF recurrence (hazard ratio [HR]: 1.20, confidence interval [CI]: 1.03-1.42, p = .02). All AF recurrence were found in patients with an AGL of >7 mm. The catheter-CF and stability were associated with an AGL of >7 mm, but not the orientation (CF-HR: 0.62, CI: 0.39-0.97, p = .038; stability-HR: 0.8, CI: 0.66-0.98, p = .027)., Conclusions: RF ablation with a low CF and poor catheter stability has a potential risk of creating large lesion gaps associated with AF recurrence., (© 2023 Wiley Periodicals LLC.)

Objectives: To investigate the effect of deep learning image reconstruction (DLIR) on the accuracy of iodine quantification and image quality of dual-energy CT (DECT) compared to that of other reconstruction algorithms in a phantom experiment and an abdominal clinical study., Methods: An elliptical phantom with five different iodine concentrations (1-12 mgI/mL) was imaged five times with fast-kilovoltage-switching DECT for three target volume CT dose indexes. All images were reconstructed using filtered back-projection, iterative reconstruction (two levels), and DLIR algorithms. Measured and nominal iodine concentrations were compared among the algorithms. Contrast-enhanced CT of the abdomen with the same scanner was acquired in clinical patients. In arterial and portal venous phase images, iodine concentration, image noise, and coefficients of variation for four locations were retrospectively compared among the algorithms. One-way repeated-measures analyses of variance were used to evaluate differences in the iodine concentrations, standard deviations, coefficients of variation, and percentages of error among the algorithms., Results: In the phantom study, the measured iodine concentrations were equivalent among the algorithms: within ± 8% of the nominal values, with root-mean-square deviations of 0.08-0.36 mgI/mL, regardless of radiation dose. In the clinical study (50 patients; 35 men; mean age, 68 ± 11 years), iodine concentrations were equivalent among the algorithms for each location (all p > .99). Image noise and coefficients of variation were lower with DLIR than with the other algorithms (all p < .01)., Conclusions: The DLIR algorithm reduced image noise and variability of iodine concentration values compared with other reconstruction algorithms in the fast-kilovoltage-switching dual-energy CT., Key Points: • In the phantom study, standard deviations and coefficients of variation in iodine quantification were lower on images with the deep learning image reconstruction algorithm than on those with other algorithms. • In the clinical study, iodine concentrations of measurement location in the upper abdomen were consistent across four reconstruction algorithms, while image noise and variability of iodine concentrations were lower on images with the deep learning image reconstruction algorithm., (© 2022.

In the current scenario, it is estimated that by 2050, there will be an additional 2.5 billion people and a 70% increase in food demand. Crop yields are not increasing fast enough to support global needs, and world agriculture is facing several serious challenges. Therefore, insects can be a nutritious alternative to meet the ever-increasing food demand in the present and future. The majority of insect consumption occurs in developing countries, with approximately 1,900 insect species consumed worldwide. Food and feed derived from them are of high quality, have a high feed conversion ratio and emit a low level of greenhouse gases. Among insects silkworms are beneficial to humans, not only because of their high nutritional value, but also because of their several pharmacological properties. Silkworm eggs, larvae, and pupae contains high amount of proteins, oils, minerals, vitamins, and several other beneficial components which are nutritious as well as have positive effect on human health. Studies have shown that silkworm pupae protect the liver, enhance immunity, inhibit apoptosis, inhibit cancer, inhibit tumor growth, inhibit microbial growth, regulate blood glucose and blood lipids, and lower blood pressure. This review paper summerized the nutritional value of different life stages of silkworm, nutritional comparison of silkworm with the major human foods, and the effects of silkworm consumption on human health, thus ittargets to generate interest toward in sericulture and improve human health by using silkworm as a nutritious food and attain sustainability in food and nutritional security., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Mahanta, Komal, Samal, Bhoi, Dubey, Pradhan, Nekkanti, Gouda, Saini, Negi, Bhateja, Jat and Jeengar.)

Background: Transgender persons in the U.S. experience high levels of violence and discrimination which have been linked to adverse substance use outcomes. Despite transgender women's higher exposure to such deleterious events compared to transgender men, studies have often aggregated both transgender women and men, obfuscating potentially unique differences between these groups. The current study, guided by the Minority Stress Model, examines differences in substance use outcomes and related correlates among transfeminine and transmasculine adults. Methods: A secondary data analysis was conducted using the 2017 Patient Characteristics Survey of public mental health facilities in the state of New York ( N  = 1387). Controlling for theoretically relevant factors, logistic regression models were estimated to examine differences between transfeminine and transmasculine adults in alcohol-related disorder (ARD) and drug use-related disorder (DURD) diagnoses, and tobacco use. Correlates of substance use disparities were also examined within gender identity groups. Results: Overall, 35% of participants were documented as using tobacco products whereas 14 and 19% were diagnosed with ARDs and DURDs, respectively. Transfeminine participants were 1.44-times more likely to be diagnosed with ARDs relative to transmasculine adults. Compared to transmasculine and White participants, transfeminine and Black participants were 1.64- and 1.59-times more likely to be diagnosed with DURDs. Conclusions: Recognizing the observed higher hazardous substance use risk among transfeminine and Black participants, findings indicate the potential role of minority stress in health outcomes of stigmatized communities. Our findings emphasize the need for identifying prevention and treatment strategies aimed at mitigating the implications of minority stress.

Korean refugee women are at risk of multiple violent victimizations throughout the migration phases. However, migration's association with mental health outcomes has received little scholarly attention. This study examined North Korean refugee women's exposure to polyvictimization-exposure to both gender-based violence (GBV) and intimate partner violence (IPV)-and explored whether polyvictimization is associated with an increased risk of psychological symptoms. Data from a snowball sample of 212 North Korean refugee women were analyzed. Polyvictimization was operationalized as No victimization (0), Only GBV (1), Only IPV (2), and Both GBV and IPV (3). The associations between polyvictimization and depression, suicidal ideation, suicide attempt, and alcohol use disorder were analyzed with multivariate analyses. Results demonstrated that 46.2% experienced GBV in either North Korea or intermediary countries, and 30.9% were victims of IPV from their current intimate partner in South Korea. Approximately 25% were victims of both GBV and IPV. Multivariate analyses revealed that GBV was the most critical factor for mental health outcomes. North Korean refugee women with only GBV or GBV and IPV had significantly higher depressive symptoms and suicidal ideation severity than those without violence victimization. Risk of suicide attempt was also significantly higher among those with only GBV (OR = 16.52, p  = .015) or both GBV and IPV (OR = 9.96, p  = .048) than those without any violence victimization. Implications for future research and interventions among North Korean refugee women are also discussed.

An effective and rapid diagnosis has great importance in tackling the ongoing COVID-19 pandemic through isolation of the infected individuals to curb the transmission and initiation of specialized treatment for the disease. It has been proven that enhanced testing capacities contribute to efficiently curbing SARS-CoV-2 transmission during the initial phases of the outbreaks. RT-qPCR is considered a gold standard for the diagnosis of COVID-19. However, in resource-limited countries expenses for molecular diagnosis limits the diagnostic capacities. Here, we present interventions of two pooling strategies as 5 sample pooling (P-5) and 10 sample pooling (P-10) in a high-throughput COVID-19 diagnostic laboratory to enhance throughput and save resources and time over a period of 6 months. The diagnostic capacity was scaled-up 2.15-folds in P-5 and 1.8-fold in P-10, reagents (toward RNA extraction and RT-qPCR) were preserved at 75.24% in P-5 and 86.21% in P-10, and time saved was 6,290.93 h in P-5 and 3147.3 h in P-10., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Mandhan, Sharma, Pandey, Chandel, Chourasia, Moun, Sharma, Sukar, Singh, Mathur, Kotnala, Negi, Gupta, Kumar, Suresh Kumar, Kumar and Singh.)

Mesenchymal stromal cells (MSCs) ameliorate pre-clinical sepsis and sepsis-associated acute kidney injury (SA-AKI) but clinical trials of single-dose MSCs have not indicated robust efficacy. This study investigated immunomodulatory effects of a novel MSC product (CD362-selected human umbilical cord-derived MSCs [hUC-MSCs]) in mouse endotoxemia and polymicrobial sepsis models. Initially, mice received intra-peritoneal (i.p.) lipopolysaccharide (LPS) followed by single i.p. doses of hUC-MSCs or vehicle. Next, mice underwent cecal ligation and puncture (CLP) followed by intravenous (i.v.) doses of hUC-MSCs at 4 h or 4 and 28 h. Analyses included serum/plasma assays of biochemical indices, inflammatory mediators and the AKI biomarker NGAL; multi-color flow cytometry of peritoneal macrophages (LPS) and intra-renal immune cell subpopulations (CLP) and histology/immunohistochemistry of kidney (CLP). At 72 h post-LPS injections, hUC-MSCs reduced serum inflammatory mediators and peritoneal macrophage M1/M2 ratio. Repeated, but not single, hUC-MSC doses administered at 48 h post-CLP resulted in lower serum concentrations of inflammatory mediators, lower plasma NGAL and reversal of sepsis-associated depletion of intra-renal T cell and myeloid cell subpopulations. Hierarchical clustering analysis of all 48-h serum/plasma analytes demonstrated partial co-clustering of repeated-dose hUC-MSC CLP animals with a Sham group but did not reveal a distinct signature of response to therapy. It was concluded that repeated doses of CD362-selected hUC-MSCs are required to modulate systemic and local immune/inflammatory events in polymicrobial sepsis and SA-AKI. Inter-individual variability and lack of effect of single dose MSC administration in the CLP model are consistent with observations to date from early-phase clinical trials., (© 2022.

Background: Some of atrial fibrillation (AF) drivers are found in normal/mild late-gadolinium enhancement (LGE) areas, as well as moderate ones. The atrial wall thickness (AWT) has been reported to be important as a possible AF substrate. However, the AWT and degree of LGEs as an AF substrate has not been fully validated in humans., Objective: The purpose of this study was to evaluate the impact of the AWT in normal/mild LGE areas on AF drivers., Methods: A total of 287 segments in 15 persistent AF patients were assessed. AF drivers were defined as non-passively activated areas (NPAs), where rotational activation was frequently observed, and were detected by the novel real-time phase mapping (ExTRa Mapping), mild LGE areas were defined as areas with a volume ratio of the enhancement voxel of 0% to <10%. The AWT was defined as the minimum distance from the manually determined endocardium to the epicardial border on the LGE-MRI., Results: NPAs were found in 20 (18.0%) of 131 normal/mild LGE areas where AWT was significantly thicker than that in the passively activated areas (PAs) (2.5 ± 0.3 vs. 2.2 ± 0.3 mm, p  < .001). However, NPAs were found in 41 (26.3%) of 156 moderate LGE areas where AWT was thinner than that of PAs (2.1 ± 0.2 mm vs. 2.23 ± 0.3 mm, p  = .02). An ROC curve analysis yielded an optimal cutoff value of 2.2 mm for predicting the presence of an NPA in normal/mild LGE areas., Conclusion: The location of AF drivers in normal/mild LGE areas might be more accurately identified by evaluating AWT., Competing Interests: The Section of Arrhythmia is supported by an endowment from Medtronic Japan and Abbott Japan.

Background: Lichens are a composite consortium of a fungus and an alga. The symbiotic organisms are naturally equipped with distinct characteristics as compared to constituting organisms separately. Lichens, due to their peculiar anatomy and physiology, are the reservoir of more than 600 unique secondary metabolites, also known as 'lichen substances'. Since ancient times, many ethnic groups from various parts of the world have known about the applications of lichens as major provenance of food/fodder, medicine, dyes, spices, perfumes, etc. Lichen substances have shown impressive antioxidant, antimicrobial, antiviral, anti-tumor, and antiinflammatory activities under experimental conditions. Usnic acid, a well-known metabolite found in several species of lichens, possesses potent antioxidant and anti-inflammatory activities. It also has significant antiproliferative potential, as revealed through testing in different cancer cell lines. Atranorin, Lecanoric acid, Norstictic acid, Lobaric acid, Stictic acid, Ramalin, Gyrophoric acid, Salazinic acid, Protolichesterinic, and Fumarprotocetraric acid are some of the other purified lichen-metabolites with potent anti-cancer activities., Objective: This study presents an overview of lichen-derived extracts and compounds showing anti-cancer (or related) properties., Method: The review comprehends different studies (in vivo and in vitro) backing up the possibility of lichenextracts and metabolites towards their use as antioxidant, anti-proliferative, anti-inflammatory, and Epithelialmesenchymal transition (EMT) -inhibiting agents., Results: Various studies carried out to date show that lichen-extracts and metabolites have a range of anti-cancer and related properties that include anti-oxidative, anti-inflammatory, anti-proliferative, pro-apoptotic, and the potential of inhibition of cancer-associated EMT that is responsible for drug resistance and metastasis of cancer cells in a substantial proportion of cases., Conclusion: Lichens are the repertoire of a plethora of lichen-metabolites with significant anti-cancer potential. However, some of the critical 'anti-cancer related' properties, such as the ability of EMT-inhibition and the potential of induction of apoptosis, are relatively less studied for several lichen compounds. Additionally, many lichen compounds need to be purified at a larger scale to explore their anti-cancer potential., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Reinfection with SARS-CoV-2 is not frequent yet the incidence rate of it is increasing globally owing to the slow emergence of drift variants that pose a perpetual threat to vaccination strategies and have a greater propensity for disease reoccurrence. Long-term protection against SARS-CoV-2 reinfection relies on the induction of the innate as well as the adaptive immune response endowed with immune memory. However, a multitude of factors including the selection pressure, the waning immunity against SARS-CoV-2 over the first year after infection possibly favors evolution of more infectious immune escape variants, amplifying the risk of reinfection. Additionally, the correlates of immune protection, the novel SARS-CoV-2 variants of concern (VOC), the durability of the adaptive and mucosal immunity remain major challenges for the development of therapeutic and prophylactic interventions. Interestingly, a recent body of evidence indicated that the gastrointestinal (GI) tract is another important target organ for SARS-CoV-2 besides the respiratory system, potentially increasing the likelihood of reinfection by impacting the microbiome and the immune response via the gut-lung axis. In this review, we summarized the latest development in SARS-CoV-2 reinfection, and explored the untapped potential of trained immunity. We also highlighted the immune memory kinetics of the humoral and cell-mediated immune response, genetic drift of the emerging viral variants, and discussed the current challenges in vaccine development. Understanding the dynamics and the quality of immune response by unlocking the power of the innate, humoral and cell-mediated immunity during SARS-CoV-2 reinfection would open newer avenues for drug discovery and vaccine designs.

Instant foods are a great convenience in today's fast moving world, aiding to reduce the time spent on the cooking process, along with the added advantage of long shelf life and ease to carry. Ingredient composition was finalized by optimizing the design variables (instantised foxtail millet, instantised green gram dal and oat flakes) using Central Composite Rotatable Design besides suitable fat and spices for the development of instant foxtail millet khichdi. Over all acceptability and water holding capacity were considered as the responses for the experimental design. The developed quick cooking (jiffy) product possessed calorific value of 525.11 kcal/100 g with good rehydration/ reconstitution properties within 4 min. Shelf stability of the khichdi packed in polypropylene (75µ) and metallised polyester (90µ) pouches was evaluated in terms of chemical, microbiological and sensorial changes. The product was found to be shelf stable for 6 months of storage in metallised polyester., (© Association of Food Scientists & Technologists (India) 2021.)
