Abstract Persistent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections have been reported in immune-compromised individuals and people undergoing immune-modulatory treatments. Although intrahost evolution has been documented, direct evidence of subsequent transmission and continued stepwise adaptation is lacking. Here we describe sequential persistent SARS-CoV-2 infections in three individuals that led to the emergence, forward transmission, and continued evolution of a new Omicron sublineage, BA.1.23, over an eight-month period. The initially transmitted BA.1.23 variant encoded seven additional amino acid substitutions within the spike protein (E96D, R346T, L455W, K458M, A484V, H681R, A688V), and displayed substantial resistance to neutralization by sera from boosted and/or Omicron BA.1-infected study participants. Subsequent continued BA.1.23 replication resulted in additional substitutions in the spike protein (S254F, N448S, F456L, M458K, F981L, S982L) as well as in five other virus proteins. Our findings demonstrate not only that the Omicron BA.1 lineage can diverge further from its already exceptionally mutated genome but also that patients with persistent infections can transmit these viral variants. Thus, there is, an urgent need to implement strategies to prevent prolonged SARS-CoV-2 replication and to limit the spread of newly emerging, neutralization-resistant variants in vulnerable patients.

Lima beans (Phaseolus lunatus) and adzuki beans (Vigna angularis) are some of the most nutritious underutilized pulses that are significant in being used as basic ingredients for the preparation of various food products. The present study aimed to determine the impact of soaking and germination on nutritional and bioactive components, in vitro protein digestibility, reducing power, metal chelating capacity, antioxidant activity, and anti-nutritional components of lima and adzuki beans. The findings showed that during the germination treatment, the in vitro protein digestibility of lima and adzuki beans increased by 14.75 and 10.98%, respectively. There was an increase in the antioxidant activity of lima beans by 33.48% and adzuki beans by 71.14% after 72 h of germination, respectively. The reducing power assay of lima and adzuki beans indicated an increase of 49.52 and 36.42%, respectively, during germination. Similarly, the flavonoid and metal chelating activity increased in lima and adzuki beans after 72 h of germination. In contrast, the anti-nutrients, such as phytic acid, tannin content, and trypsin inhibitor activity, decreased significantly p < 0.05 after 72 h of germination. These results are encouraging and allow for utilizing the flour obtained from the germinated beans in functional bakery products, which can contribute to eradicating protein deficiency among some population groups. At the same time, promoting soaking and germination of the beans as a way to enhance the nutritional quality and reduce anti-nutrients can contribute to the interest in these underutilized pulses. They could be seen as an additional tool to improve food security.

In the present era of climate change, underutilized crops such as rice beans and adzuki beans are gaining prominence to ensure food security due to their inherent potential to withstand extreme conditions and high nutritional value. These legumes are bestowed with higher nutritional attributes such as protein, fiber, vitamins, and minerals than other major legumes of the Vigna family. With the typical nutrient evaluation methods being expensive and time-consuming, non-invasive techniques such as near infrared reflectance spectroscopy (NIRS) combined with chemometrics have emerged as a better alternative. The present study aims to develop a combined NIRS prediction model for rice bean and adzuki bean flour samples to estimate total starch, protein, fat, sugars, phytate, dietary fiber, anthocyanin, minerals, and RGB value. We chose 20 morphometrically diverse accessions in each crop, of which fifteen were selected as the training set and five for validation of the NIRS prediction model. Each trait required a unique combination of derivatives, gaps, smoothening, and scatter correction techniques. The best-fit models were selected based on high RSQ and RPD values. High RSQ values of >0.9 were achieved for most of the studied parameters, indicating high-accuracy models except for minerals, fat, and phenol, which obtained RSQ

ABSTRACTMonkeypox (MPOX) is a zoonotic disease endemic to regions of Central/Western Africa. The geographic endemicity of MPV has expanded, broadening the human-monkeypox virus interface and its potential for spillover. Since May 2022, a large multi-country MPV outbreak with no proven links to endemic countries has originated in Europe and has rapidly expanded around the globe, setting off genomic surveillance efforts. Here, we conducted a genomic analysis of 23 MPV-infected patients from New York City during the early outbreak, assessing the phylogenetic relationship of these strains against publicly available MPV genomes. Additionally, we compared the genomic sequences of clinical isolates versus culture-passaged samples from a subset of samples. Phylogenetic analysis revealed that MPV genomes included in this study cluster within the B.1 lineage (Clade IIb), with some of the samples displaying further differentiation into five different sub-lineages of B.1. Mutational analysis revealed 55 non-synonymous polymorphisms throughout the genome, with some of these mutations located in critical regions required for viral multiplication, structural and assembly functions, as well as the target region for antiviral treatment. In addition, we identified a large majority of polymorphisms associated with GA > AA and TC > TT nucleotide replacements, suggesting the action of human APOBEC3 enzyme. A comparison between clinical isolates and cell culture-passaged samples failed to reveal any difference. Our results provide a first glance at the mutational landscape of early MPV-2022 (B.1) circulating strains in NYC.

Seventeen pigmented maize cultivated in different locations of India were collected and evaluated for their nutritional, anti-nutritional and starch profile. A wide variation was observed in all the parameters evaluated. Protein and total dietary fiber content varied between 7.18 to 10.85 g/100 g and 8.76 to 14.04 g/100 g, respectively. Among the water-soluble vitamins, B2 varied from 0.071 to 0.134; B3, 1.50 to 2.79; B5, 0.17 to 0.70 and B6, 0.141 to 0.245 mg/100 g; while total tocopherol and tocotrienol varied 1417 to 2246 μg/100 g and 18.57 to 30.01 μg/100 g, respectively. The resistant starch, total starch and amylose varied significantly and observed between 0.49 to 4.78 %, 61.33 to 69.65 % and 10.91 to 32.01 %, respectively. Among the minerals, Fe and Zn were observed between 1.51 to 5.01 and 2.25 to 5.51 mg/100 g, respectively. Total polyunsaturated and total monounsaturated fatty acids were observed up to 45.72 and 55.54 %, respectively. Amongst the anti-nutrients, phytate was detected the lowest in Laal makki, whereas total and soluble oxalates were the lowest in Kashmiri red maize.

Millet varieties were analyzed for nutritional, antinutritional, mineral and phenolic profiles. Inhibition potential of phenolic acids for enzyme inhibition ,activity was estimated, alongside starch digestibility of millet grains was evaluated. Finger millet was found to have high contents of Ca, Mn and Cu minerals. Proso and pearl millet had high protein content, whereas kodo and foxtail millet contained high content of dietary fiber. Phytic acid was comparatively higher in kodo millet, whereas oxalic acid and total tannin content was abundant in finger millet. Total phenolic content and total flavonoid content in bound phenolic fractions were comparatively higher than the free phenolic fractions and total anthocyanin content was found highest in finger millet followed by kodo and pearl millet. The millet varieties showed optimum antioxidant potential studied through different assay methods. Ferulic acid was predominantly found among all the millets in bound fraction of phenolic extract. Furthermore, phenolic acids were used to investigate different docking techniques with α-amylase, α-glucosidase, and leptin receptor enzymes. Docking studies revealed, chlorogenic acid had a high docking score and a high binding affinity against α-amylase, α-glucosidase, and leptin receptor enzymes.

Introduction: Lockdown measures in response to the COVID-19 pandemic had an appreciable impact on the education of all medical, dental and non-medical healthcare professional students. These included the closure of universities necessitating a rapid move to e-learning and a new practical approach to conducting teaching-learning classes. However, initially, there was a lack of knowledge and expertise regarding e-learning approaches and the affordability of internet bundles and equipment. Materials and Methods: We conducted two pilot studies to assess such current challenges, replaced by a two-stage approach including a full investigation involving 32 private and public universities during the early stages of the pandemic, followed by a later study assessing the current environment brought about by the forced tops. Results: The top challenges at the start of the pandemic included a lack of familiarity with the e-learning approaches, the cost of the internet, a lack of IT equipment and the quality of the classes. To address identified challenges, universities offered support to staff and students. Since then, e-learning approaches have widened the possibilities for teaching and learning at convenient times. However, challenges remain. Conclusions: There were considerable challenges at the start of the pandemic. Several key issues have been addressed with hybrid learning here to stay. The remaining challenges include a lack of ICT equipment. However, new innovations will continue.

Brown trout is a common type of fish grown for consumption in open and flowing fish ponds on the rivers of Bosnia and Herzegovina. We conducted this study during three seasons (spring, summer and autumn) to obtain a complete picture of the morphological and histological characteristics of selected trout tissues. The physicochemical characteristics of the water from the Pliva River near Pljeva and the fish pond where intensive breeding of trout is carried out were analyzed. These analyses have shown that there are no major deviations in water quality and that the water in the pond is of excellent quality. A total of 90 trout were harvested during all three seasons and their morphometric characteristics were determined by analyzing ten parameters. After the dissection of all individuals, histological and stereological analysis was performed to compare the tissues of the liver, stomach, gills and muscles. These analyses showed significant differences in the histoarchitecture of selected trout tissues from the pond compared to the river. Liver tissue had altered hepatocyte shape and presence of adipocytes; stomach tissue had stronger mucosa and weaker muscle layer; gill tissue had lower respiratory lamellae; while muscle tissue had a significant presence of adipose tissue in brown trout living in the fish pond compared to those in the river. All these changes are due to the quality of commercial feed and the inability to move freely.

Two major future challenges are an increase in global earth temperature and a growing world population, which threaten agricultural productivity and nutritional food security. Underutilized crops have the potential to become future climate crops due to their high climate-resilience and nutritional quality. In this context, C4 pseudocereals such as grain amaranths are very important as C4 crops are more heat tolerant than C3 crops. However, the thermal sensitivity of grain amaranths remains unexplored. Here, Amaranthus hypochondriacus was exposed to heat stress at the vegetative and reproductive stages to capture heat stress and recovery responses. Heat Shock Factors (Hsfs) form the central module to impart heat tolerance, thus we sought to identify and characterize Hsf genes. Chlorophyll content and chlorophyll fluorescence (Fv/Fm) reduced significantly during heat stress, while malondialdehyde (MDA) content increased, suggesting that heat exposure caused stress in the plants. The genome-wide analysis led to the identification of thirteen AhHsfs, which were classified into A, B and C classes. Gene expression profiling at the tissue and developmental scales resolution under heat stress revealed the transient upregulation of most of the Hsfs in the leaf and inflorescence tissues, which reverted back to control levels at the recovery time point. However, a few Hsfs somewhat sustained their upregulation during recovery phase. The study reported the identification, physical location, gene/motif structure, promoter analysis and phylogenetic relationships of Hsfs in Amaranthus hypochondriacus. Also, the genes identified may be crucial for future gene functional studies and develop thermotolerant cultivars.

Diazepam-based drugs are widely used today in human treatment. Diazepam may be a primary drug aimed at treating neurological diseases or an associated drug in the treatment of other diseases in the purpose of symptomatic therapy. The sedative effect of diazepam characterizes it as a drug that people usually use on their own and without a doctor’s supervision. Directly, but also through influencing the nervous system, diazepam disrupts proper functioning of all body organs. The purpose of this paper was to examine the effects of diazepam on blood and cytohistological parameters of rats in an in vivo experiment. Mallory-Azan and immunochistochemical staining methods BLX-CX and Survivin tissues of liver, kidney and spleen of rats were used to achieve the set goal. Cytometric analysis of rats detected cells in apoptosis and measurements of stereological parameters were made using a system according to Cavalier’s principle. Results of analysis of hematological and histological parameters indicate a detrimental effect of diazepam on blood parameters, as well as on structure and functioning of the liver, kidneys and spleen of rats. This paper is a foundation for further detailed scientific research with the aim of elucidating all harmful effects that diazepam has on all organs in the body of rats. This data could serve as a starting point for future studies in clinical pharmacology on therapeutic protocols for usage of diazepam-based sedatives.

Context: Adult population visiting COVID vaccination center is a potential teachable moment for screening and preventive advice on non-communicable diseases. Objectives: The objective of this study was to assess the proportion of vaccinees volunteering for screening and to know the proportion of newly detected hypertensives and diabetics among the screened vaccinees at COVID-19 vaccination center. Setting and Design: This descriptive, cross-sectional, operational research study was carried out at the COVID vaccination center at a medical college in central Gujarat from July to September 2021. Methods: After receiving the vaccine, the vaccinee was offered screening through a community-based assessment checklist for risk factors of non-communicable diseases, blood pressure, and blood sugar measurement. Those volunteering for this screening received a slip mentioning their risk score, blood pressure and blood sugar reading, and relevant health information and disease prevention advice. The study variables were acceptability (proportion of vaccinees volunteering for screening) and yield (newly detected hypertensives and diabetics among those screened). Results: Among vaccinees, 27.7% volunteered for risk scoring and blood pressure measurement, whereas 8.3% volunteered for blood sugar measurement. Around 15.5% of vaccinees had high-risk scores as per the community-based assessment checklist. The yield of freshly detected high blood pressure and high blood sugar was 19.3% and 10.5%, respectively. The yield was similar even among vaccinees under 30 years of age. Conclusions: Vaccinees demonstrated interest in undergoing screening for non-communicable diseases. Yield indicates that such screening is worth the effort.

Introduction: The early approaches to prevent the spread of COVID-19 included lockdown and social distancing measures, leading to university closures. These measures forced unparalleled changes to the delivery of healthcare education. Concerns included the preparedness of faculty and students to e-learning as well as the routine availability and funding of equipment and internet bundles. This needed addressing with fully trained healthcare professionals required given rising inappropriate use of antibiotics in India, growing prevalence of non-communicable diseases as well as an increasing number of patients with joint comorbidities. Consequently, there is a need to ascertain the current impact of the pandemic on healthcare student education across India. Materials and Methods: This was a pilot study among 10 purposely selected healthcare educators in both private and public universities. The questionnaire built on published studies. Results: Identified challenges included a lack of familiarity with online education, no bedside teaching, lack of equipment and affordability of internet bundles, poor internet connectivity and postponed examinations. Ways forward included training faculty on e-learning, providing students with loans and other financial support to purchase equipment and internet bundles, establishing COVID-19 prevention protocols and protective equipment, recording lectures and tutorials to make up for lost time and simulated methods to teach clinical aspects. Conclusion: Despite challenges, there was a rapid move to online learning among surveyed universities. Alongside this, courses to address lack of familiarity with e-learning approaches with hybrid teaching approaches here to stay. The next step will be to undertake a wider study and to use the combined findings to provide future guidance.

The COVID-19 pandemic caused by SARS-CoV-2 has caused millions of infections and deaths worldwide. Limited treatment options and the threat from emerging variants underline the need for novel and widely accessible therapeutics. G-quadruplexes (G4s) are nucleic acid secondary structures known to affect many cellular processes including viral replication and transcription. We identified heretofore not reported G4s with remarkably low mutation frequency across >5 million SARS-CoV-2 genomes. The G4 structure was targeted using FDA-approved drugs that can bind G4s - Chlorpromazine (CPZ) and Prochlorperazine (PCZ). We found significant inhibition in lung pathology and lung viral load of SARS-CoV-2 challenged hamsters when treated with CPZ or PCZ that was comparable to the widely used antiviral drug Remdesivir. In support, in vitro G4 binding, inhibition of reverse transcription from RNA isolated from COVID-infected humans, and attenuated viral replication and infectivity in Vero cell cultures were clear in case of both CPZ and PCZ. Apart from the wide accessibility of CPZ/PCZ, targeting relatively invariant nucleic acid structures poses an attractive strategy against viruses like SARS-CoV-2, which spread fast and accumulate mutations quickly.

Chagas disease is a complex zoonosis caused by Trypanosoma cruzi. The diagnosis of this infection is complex and molecular tools are suggested to detect the parasite in blood samples. A long-standing question arises in Chagas disease molecular diagnostics and is related to the feasibility of using epimastigotes in standard curves to quantify parasitic loads. Herein, we conducted experiments running standard curves with all the known life stages of T. cruzi. Our results indicate that regardless of the life stage employed, there are no statistically significant differences when calculating parasitic loads in blood samples. Our results have practical implications from a laboratory perspective in terms of the usability of epimastigotes to build standard curves for T. cruzi pan-stage assessment. Future studies are needed to further improve T. cruzi molecular diagnostic methods and enhance their impact in clinical practice.

Barnyard(Echinochloautilis),Finger (Eleusinecoracana), Foxtail (Setaria italic), Kodo (Paspalumsetaceum) Little (Panicum sumatrense),Pearl (Pennisetumglaucum), and Proso(Penicummiliaceum) millets are staple foods for Indian and African diets.Post harvest handling primarily the storage conditions during rainy season leads to significant losses of millets in Asia and Africa.Poor storage conditions during rainy seasons lead to germination and fungal growth due to poor storage infrastructure facilities in Asia and Africa. To prevent food losses and to understand the irradiation influence on biopolymer functionality, the millets were irradiated at a dosage of 2.5 and 5 kGy at 12% and 14% moisture contents and milled to prepare the flour.The flour was analysed for microbial count and changes in structural and functional properties to understand the implications on end-use. Post irradiation, oil absorption, emulsion capacity, and water absorption decreased significantly (p≤0.05), while foaming capacity, emulsion stability, and foaming stability increased. Hunter color values L*, a*, and b* showed different trends with an increase in dosage of irradiation.FTIR studies revealed that there were shifts in the functional groups, primarily a decrease in the intensities of O-H, C-H, and O=C stretches and the bending mode of water.Scanning electron microscopy at 2500x magnification revealed different morphological shapes from spherical, polygonal, and a few spherical granules. In our studies we observed that gamma irradiation decreases the nicrobial count and at the same time deactivates the germinating enzymes.Therefore the irradiation treatment is an affordable and effective methodology to prevent post harvest losses of millets In general, irradiation influenced the millet flour functionality and a decrease in microbial with irradiation , therefore,irradiation can help prevent post-harvestmillet lossesin developing nations. Studies on controlled irradiation can help improve the flour properties for better end use

ABSTRACT Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants are characterized by differences in transmissibility and response to therapeutics. Therefore, discriminating among them is vital for surveillance, infection prevention, and patient care. While whole-genome sequencing (WGS) is the “gold standard” for variant identification, molecular variant panels have become increasingly available. Most, however, are based on limited targets and have not undergone comprehensive evaluation. We assessed the diagnostic performance of the highly multiplexed Agena MassARRAY SARS-CoV-2 Variant Panel v3 to identify variants in a diverse set of 391 SARS-CoV-2 clinical RNA specimens collected across our health systems in New York City, USA and Bogotá, Colombia (September 2, 2020 to March 2, 2022). We demonstrated almost perfect levels of interrater agreement between this assay and WGS for 9 of 11 variant calls (κ ≥ 0.856) and 25 of 30 targets (κ ≥ 0.820) tested on the panel. The assay had a high diagnostic sensitivity (≥93.67%) for contemporary variants (e.g., Iota, Alpha, Delta, and Omicron [BA.1 sublineage]) and a high diagnostic specificity for all 11 variants (≥96.15%) and all 30 targets (≥94.34%) tested. Moreover, we highlighted distinct target patterns that could be utilized to identify variants not yet defined on the panel, including the Omicron BA.2 and other sublineages. These findings exemplified the power of highly multiplexed diagnostic panels to accurately call variants and the potential for target result signatures to elucidate new ones. IMPORTANCE The continued circulation of SARS-CoV-2 amid limited surveillance efforts and inconsistent vaccination of populations has resulted in the emergence of variants that uniquely impact public health systems. Thus, in conjunction with functional and clinical studies, continuous detection and identification are quintessential to informing diagnostic and public health measures. Furthermore, until WGS becomes more accessible in the clinical microbiology laboratory, the ideal assay for identifying variants must be robust, provide high resolution, and be adaptable to the evolving nature of viruses like SARS-CoV-2. Here, we highlighted the diagnostic capabilities of a highly multiplexed commercial assay to identify diverse SARS-CoV-2 lineages that circulated from September 2, 2020 to March 2, 2022 among patients seeking care in our health systems. This assay demonstrated variant-specific signatures of nucleotide/amino acid polymorphisms and underscored its utility for the detection of contemporary and emerging SARS-CoV-2 variants of concern.

BackgroundValue-driven career attitude (VDCA) is considered a dimension of a protean career attitude (PCA). Individuals with this attitude seek out personally meaningful experiences and set their own psychological career success standards. This study investigates the association between value-driven career attitude and job performance. It looks at how organizational citizenship behavior affects the relationship between value-driven career attitudes and job performance.MethodsA self-reported questionnaire was used to collect data from 400 random employees of SMEs in Pakistan during the early pandemic. We chose Cochran’s formula to determine the appropriate sample size, and PLS-SEM was used to analyze the model. P-O fit and self-determination theory is the theoretical lenses used in this study. The underpinning theories to this study enable the researchers to establish a link between VDCA, OCB, and job performance.ResultsBy analyzing a sample of 400 employees from active enterprises, we discover that VDCA contributes to an improvement in job performance. Furthermore, OCB plays an intervening effect in the relationship between VDCA and job performance. Thus, the study provided evidence for the underpinning models of P-O fit and self-determination theory.ConclusionThis study adds to the body of knowledge by investigating the connections between VDCA, OCB, and job performance in SMEs. The existing literature sheds scant light on these linkages, leaving a gap that this study will address. The current study expands on other themes to provide an in-depth analysis of many under-explored PCA outcomes, which may open up new avenues for future researchers to broaden and strengthen PCA with other constructs.

Summary: Background: Although the proportion of ethnicities representing under‐represented minorities in medicine (URM) in the general population has significantly increased, URM enrolment in medical schools within the USA has remained stagnant in recent years. Methods: This study sought to examine the effect of an immersion in community medicine (ICM) programme on secondary school students’ desire to enter the field of medicine and serve their communities. The authors asked all 69 ICM alumni to complete a 14‐question survey consisting of six demographic, four programme and four career questions, rated on a Likert scale of 1 (completely disagree) to 5 (completely agree), coupled with optional free‐text questions. Data were analysed using GraphPad prism and nvivo software. Results: A total of 61 students responded, representing a response rate of 88.4 per cent, with a majority of respondents (73.7%) from URM backgrounds. An overwhelming majority of students agreed (with a Likert rating of 4 or 5) that the ICM programme increased their interest in becoming a physician (n = 56, 91.8%). Students reported shadowing patient–student–physician interactions to be the most useful (n = 60, 98.4%), and indicated that they felt that they would be more likely to lead to serving the local community as part of their future careers (n = 52, 85.3%). Of the students that were eligible to apply to medical school (n = 13), a majority (n = 11, 84.6%) have applied to medical school. URM enrolment in medical schools within the USA has remained stagnant in recent years Discussion: Use of a community medicine immersion programme may help encourage secondary students from URM backgrounds to gain the confidence to pursue a career in medicine and serve their communities. Further examination of these programmes may yield novel insights into recruiting URM students to medicine. [ABSTRACT FROM AUTHOR]

Potato is a temperate crop consumed globally as a staple food. High temperature negatively impacts the tuberization process, eventually affecting crop yield. DNA methylation plays an important role in various developmental and physiological processes in plants. It is a conserved epigenetic mark determined by the dynamic concurrent action of cytosine-5 DNA methyltransferases (C5-MTases) and demethylases (DeMets). However, C5-MTases and DeMets remain unidentified in potato, and their expression patterns are unknown under high temperatures. Here, we performed genome-wide analysis and identified 10 C5-MTases and 8 DeMets in potatoes. Analysis of their conserved motifs, gene structures, and phylogenetic analysis grouped C5-MTases into four subfamilies (StMET, StCMT3, StDRM, and StDNMT2) and DeMets into three subfamilies (StROS, StDML, and StDME). Promoter analysis showed the presence of multiple cis-regulatory elements involved in plant development, hormone, and stress response. Furthermore, expression dynamics of C5-MTases and DeMets were determined in the different tissues (leaf, flower, and stolon) of heat-sensitive (HS) and heat-tolerant (HT) genotypes under high temperature. qPCR results revealed that high temperature resulted in pronounced upregulation of CMT and DRM genes in the HT genotype. Likewise, demethylases showed strong upregulation in HT genotype as compared to HS genotype. Several positive (StSP6A and StBEL5) and negative (StSP5G, StSUT4, and StRAP1) regulators are involved in the potato tuberization. Expression analysis of these genes revealed that high temperature induces the expression of positive regulators in the leaf and stolon samples of HT genotype, possibly through active DNA demethylation and RNA-directed DNA methylation (RdDM) pathway components. Our findings lay a framework for understanding how epigenetic pathways synergistically or antagonistically regulate the tuberization process under high-temperature stress in potatoes. Uncovering such mechanisms will contribute to potato breeding for developing thermotolerant potato varieties.
