Sheehan Syndrome Unmasked by Adrenal Crisis Secondary to Severe Dengue Fever.

Background: Sheehan syndrome is the infarction of a pituitary gland that has been physiologically enlarged as a result of postpartum bleeding. Agalactorrhea and amenorrhea are classic symptoms, but a constellation of manifestations occurs in both the acute and chronic forms. These manifestations can remain largely nonemergent unless Sheehan syndrome is complicated by severe adrenal dysfunction secondary to an inciting event such as dengue. We present a case of Sheehan syndrome that was uncovered in a patient with a dengue infection presenting as adrenal crisis. Case Report: A 45-year-old female presented with symptoms of acute gastroenteritis and severe dehydration. Her medical history was significant for secondary amenorrhea for 14 years after her last delivery followed by symptoms of endocrine dysfunction. At presentation, the patient was in adrenal crisis with hypotension, hypoglycemia, and hyperthermia. Dengue nonstructural protein 1 antigen was positive, along with signs of plasma leakage. Bloodwork showed bicytopenia with abnormal liver enzymes. Ultrasonography and computed tomography of the abdomen were suggestive of serositis with acalculous cholecystitis. Magnetic resonance imaging of the brain revealed an empty sella. Anterior pituitary hormone levels were significantly decreased with low serum cortisol, and the patient's thyroid profile analysis suggested secondary hypothyroidism. The final diagnosis was Sheehan syndrome presenting as adrenal crisis precipitated by severe dengue fever. The patient was managed conservatively and discharged on hormone supplement therapy. Conclusion: Sheehan syndrome is an important cause of panhypopituitarism in the developing world. Knowledge of Sheehan syndrome is important to help prevent its occurrence and reduce its resultant multifactorial effects.

Study of Association of Erectile Dysfunction with Metabolic Syndrome and Its Correlation with Endothelial Dysfunction in an Indian Population.

BACKGROUND: Metabolic syndrome (MS) has emerged as a new health risk, and its associated metabolic derangements have detrimental effects on the cardiovascular system. In recent years, MS has been reported to affect reproductive health in males. It has been reported to be associated with erectile dysfunction (ED) and has been attributed to be due to endothelial dysfunction. Poor endothelial function in ED usually affects small-sized vasculature, so it can be looked at as a predictor for the endothelial dysfunction of macro vasculature. The aim of the present study was to determine the association of ED in patients with MS and to determine its correlation with endothelial dysfunction. MATERIALS AND METHODS: It was a hospital-based case-control study in which 120 male patients with MS and 120 age-matched controls were enroled. Demographic profiles, anthropometry, past illnesses, and medical history of patients were obtained. MS was diagnosed according to the International Diabetes Federation (IDF) criteria and was measured using the flow-mediated dilation (FMD) method with the help of ultrasound used to assess endothelial dysfunction. Diagnosis of ED was based on the International Index of Erectile Function (IIEF) scale. RESULTS: The study participants had a mean age of 40.91 ± 11.41 years. The majority of cases (57.5%) had ≤6 months of history of MS. The prevalence of ED was 31.7% in cases compared to 5% in controls, thus showing a significant difference between cases and controls. Mean IIEF scores were significantly lower in cases (18.82 ± 5.59) compared to those in controls (23.00 ± 2.57). A moderate positive and significant correlation was observed between FMD and IIEF scores. With an increasing number of MS components, there was a significant increase in the prevalence of ED. Those with ED had significantly lower mean FMD values (5.1 ± 1.1%) compared to those not having ED (10.9 ± 3.3%). CONCLUSION: The findings of the present study showed that there is a significant association between ED and MS. We observed that the increase in components of MS increased the prevalence of ED in MS. Endothelial dysfunction measured by FMD was correlated with ED.

Deep-Learning-Based Arrhythmia Detection Using ECG Signals: A Comparative Study and Performance Evaluation.

Heart diseases is the world's principal cause of death, and arrhythmia poses a serious risk to the health of the patient. Electrocardiogram (ECG) signals can be used to detect arrhythmia early and accurately, which is essential for immediate treatment and intervention. Deep learning approaches have played an important role in automatically identifying complicated patterns from ECG data, which can be further used to identify arrhythmia. In this paper, deep-learning-based methods for arrhythmia identification using ECG signals are thoroughly studied and their performances evaluated on the basis of accuracy, specificity, precision, and F1 score. We propose the development of a small CNN, and its performance is compared against pretrained models like GoogLeNet. The comparative study demonstrates the promising potential of deep-learning-based arrhythmia identification using ECG signals.

Temperature differences between sites lead to altered phenylpropanoid metabolism in a varietal dependent manner.

Elevated temperature has already caused a significant loss of wine growing areas and resulted in inferior fruit quality, particularly in arid and semi-arid regions. The existence of broad genetic diversity in V. vinifera is key in adapting viticulture to climate change; however, a lack of understanding on the variability in berry metabolic response to climate change remains a major challenge to build ad-hoc strategies for quality fruit production. In the present study, we examined the impact of a consistent temperature difference between two vineyards on polyphenol metabolism in the berries of 20 red V. vinifera cultivars across three consecutive seasons (2017-2019). The results emphasize a varietal specific response in the content of several phenylpropanoid metabolites; the interaction factor between the variety and the vineyard location was also found significant. Higher seasonal temperatures were coupled with lower flavonol and anthocyanin contents, but such reductions were not related with the level of expression of phenylpropanoid related genes. Hierarchical clustering analyses of the metabolic data revealed varieties with a location specific response, exceptional among them was Tempranillo, suggesting a greater susceptibility to temperature of this cultivar. In conclusion, our results indicate that the extensive genetic capacity of V. vinifera bears a significant potential to withstand temperature increase associated with climate change.

A study of serum brain-derived neurotrophic factor level in individuals with obsessive compulsive disorder and their first-degree relatives as compared to the healthy population.

Background: The nosological tradition in psychiatry defines diagnostic criteria for disorders based on expert consensus than objective biological markers reflecting underlying neurobiological correlates. Endophenotypes have been researched as heritable biological markers that can be quantified and defined to represent intermediate measures of a psychiatric illness. In obsessive-compulsive disorder (OCD), various putative biomarkers such as neuropsychological, neurophysiological, neuroradiological, brain-derived neurotrophic factor (BDNF), etc., have been explored. Aim: The study aimed to compare levels of serum BDNF in individuals with OCD and their unaffected first-degree relatives (FDR) with healthy controls (HC). Methods: This cross-sectional study compared serum BDNF levels in medication-free/naive individuals with OCD (n = 30) to their FDR (n = 30) and age-sex matched HC (n = 30). Intergroup comparison was done using analysis of variance (ANOVA) and post-hoc Tukey's test. Correlation analysis was conducted to find the relationship of sociodemographic and clinical correlates to serum BDNF as well as dimensional subtypes of OCD. Results: No significant difference in BDNF levels was observed between OCD and HC (P = 0.13) but a significantly higher level was found in the FDR group compared to age-sex matched HC (P = 0.02). Conclusion: BDNF levels may have a complex interplay influencing the genetic inheritance and clinical manifestations of OCD. Further research is required before considering it a viable biomarker.

Oxidative Stress in Wistar Rats Under Acute Restraint Stress and Its Modulation by Antioxidants and Nitric Oxide Modulators.

BACKGROUND: Several pathogenic conditions leading to morbidity, including cancer, aging, diabetes, reperfusion injury, cardiovascular disease, and neurological disorders, are known to be exacerbated by oxidative stress. Antioxidant therapy is effective in the treatment of such disorders and appears to be a potential therapeutic technique to reduce oxidative stress. The aim of our study is to investigate the antioxidant effects of L-ascorbic acid and nitric oxide (NO) modulators on rats suffering from oxidative stress induced by acute restraint stress (RSx1). METHODOLOGY: In this in vivo study, Wistar rats were subjected to one hour of restraint stress on day 21 to induce oxidative stress. Superoxide dismutase (SOD), total antioxidant capacity (TAC), catalase, glutathione (GSH), and malondialdehyde (MDA) were used to assess the antioxidant effects. IBM Corp. Released 2013. IBM SPSS Statistics for Windows, Version 22.0. Armonk, NY: IBM Corp. was used for data analysis. RESULTS: Compared to vehicle groups, acute restraint stress (RSx1) dramatically increased MDA levels while decreasing GSH, SOD, total antioxidant capacity, and catalase. L-NAME, 7-NI, AG (50 mg/kg each), and L-ascorbic acid (200 mg/kg) reversed the changes in SOD, MDA, GSH, total antioxidant capacity, and catalase levels. The NO precursor L-arginine (1000 mg/kg) and NO synthase inhibitors followed the same trend. CONCLUSION: Our study findings highlight the complex role of antioxidants and NO modulators in the pathogenesis of diseases, as evidenced by the reversal of oxidative stress indicators. Antioxidant therapy, with its potential to mitigate oxidative stress, emerges as a viable treatment option for a range of pathological conditions associated with oxidative stress.

Influence of late pruning practice on two red skin grapevine cultivars in a semi-desert climate.

Continually increasing global temperature could severely affect grape berry metabolite accumulation and ultimately wine polyphenol concentration and color intensity. To explore the effect of late shoot pruning on grape berry and wine metabolite composition, field trials were carried out on Vitis vinifera cv. Malbec and cv. Syrah grafted on 110 Richter rootstock. Fifty-one metabolites were detected and unequivocally annotated employing UPLC-MS based metabolite profiling. Integrating the data using hierarchical clustering showed a significant effect of late pruning treatments on must and wine metabolites. Syrah metabolite profiles were characterized by a general trend of higher metabolite content in the late shoot pruning treatments, while Malbec profiles did not show a consistent trend. In summary, late shoot pruning exerts a significant effect, though varietal specific, on must and wine quality-related metabolites, possibly related to enhanced photosynthetic efficiency, which should be taken into consideration when planning mitigating strategies in warm climates.

Microplastic intrusion into the zooplankton, the base of the marine food chain: Evidence from the Arabian Sea, Indian Ocean.

Microplastics (MPs) are ubiquitous in the marine environment, yet information regarding their occurrence in the food web is limited. We investigated the concentration and composition of MPs in water and diverse zooplankton groups from the Arabian Sea basin. Forty-one zooplankton tows were collected with a bongo net (330 µm mesh) from the Arabian Sea in January 2019. MPs in the surface water varied between 0 and 0.055 particles/m3, with a relatively higher concentration (0.013 ± 0.002 particles/m3) in the central Arabian Sea. Though fibrous MPs were most abundant in the seawater (77.14 %), zooplankton prefers small fragments (55.3 %). The size of MPs was distinctly smaller (277.1 ± 46.74 µm) in zooplankton than that in seawater (864.32 ± 73.72 µm), and MPs bioaccumulation was observed in almost all the zooplankton functional groups. Polymer composition revealed polyamide, polyethylene, polypropylene, and PVC were abundant in water and zooplankton, suggesting that the textile, fishing, shipping, and packaging industries are significant sources. The prevailing northeasterly winds, strong West India Coastal Current, and conducive westward radiated Rossby wave during January 2019 have carried the microplastic contaminated water mass away from the coast, posing a threat to the open ocean ecosystems. These results demand further attention to investigate the state of plastic pollution in the Arabian Sea basin.

Optoelectronic design and charge transport properties of Benzodifuran (BDF) isomers for organic electronic devices: DFT/TD-DFT insights.

The primary goal of this work is to provide a comprehensive analysis of the charge transport and optoelectronic characteristics of all the isomers of benzodifuran (BDF) for organic electronic devices in order to suggest qualified materials/candidates for organic photovoltaic devices. Density functional theory (DFT) calculations were performed for all possible isomers of BDF and results are compared with corresponding experimental known isomers. Time Dependent-Density Functional Theory (TD-DFT) is used for the calculation of the absorption and HOMO-LUMO energy levels. To characterize the electronic charge transport state in these isomers, the ionization potentials (IP), reorganization energies (hole and electron), and electron affinities (EA) of all the isomers are investigated. Comparatively, all the BDF isomers are having low electron and hole reorganization energies and hence they can be used in the organic electronic material fabrication.

Assessment of supernatural attitude toward mental health among tribal and non-tribal populations.

Background: In India, only about 10% of persons with psychiatric illnesses receive evidence-based treatments. Stigma, mistrust in allopathic medicine, allegiance toward faith healers, cultural and traditional practices, and beliefs are some of the major hindrances to the treatment of mentally ill patients. Aim: To assess supernatural attitudes toward mental health among tribal and non-tribal populations. Materials and Methods: A total of 100 subjects were included in the study after informed consent, 50 of whom were tribal and 50 non-tribal. All were required to fill a self-constructed proforma, the Supernatural Attitude Questionnaire (SAQ), and the Attitudes Toward Seeking Professional Psychological Help Scale-Short Form (ATSPPH-SF). The scales were scored, compiled, and statistically analyzed. Results: The tribal and non-tribal subjects were well-matched on socio-demographic variables. The score of SAQ was significantly higher in the tribal group as compared to the non-tribal group. On the ATSPPH-SF, the scores of the two groups were not significant. Conclusion: Even though the tribal populations of India hold a higher supernatural attitude toward mental illnesses as compared to the non-tribal populations, their treatment-seeking attitude remains unaffected.

Root system architecture in rice: impacts of genes, phytohormones and root microbiota.

To feed the continuously expanding world's population, new crop varieties have been generated, which significantly contribute to the world's food security. However, the growth of these improved plant varieties relies primarily on synthetic fertilizers, which negatively affect the environment and human health; therefore, continuous improvement is needed for sustainable agriculture. Several plants, including cereal crops, have the adaptive capability to combat adverse environmental changes by altering physiological and molecular mechanisms and modifying their root system to improve nutrient uptake efficiency. These plants operate distinct pathways at various developmental stages to optimally establish their root system. These processes include changes in the expression profile of genes, changes in phytohormone level, and microbiome-induced root system architecture (RSA) modification. Several studies have been performed to understand microbial colonization and their involvement in RSA improvement through changes in phytohormone and transcriptomic levels. This review highlights the impact of genes, phytohormones, and particularly root microbiota in influencing RSA and provides new insights resulting from recent studies on rice root as a model system and summarizes the current knowledge about biochemical and central molecular mechanisms.

Unraveling the plastic degradation potentials of the plastisphere-associated marine bacterial consortium as a key player for the low-density polyethylene degradation.

The omnipresent accumulation and non-degradable nature of plastics in the environment are posing an ever-increasing ecological threat. In this study, a total of 97 bacteria were isolated from macroplastic debris collected from the coastal environments of Andaman Island. The isolates were screened for LDPE degradation potential and were identified based on phenotypic, biochemical, and molecular characterization. 16S rDNA-based identification revealed that three-three isolates of each belong to the genus Oceanimonas and Vibrio, two were closely related to the genus Paenibacillus whereas, one-one was associated with the genus Shewanella, Rheinheimera, and Bacillus, respectively. A bacterial consortium was formulated using the top four isolates based on their individual LDPE degradation potentials. A significant increase (p < 0.05) in the mean LDPE degradation (47.07 ± 6.67% weight-loss) and change in thickness was observed after 120 days of incubation. FTIR spectrum, 13C NMR, and TG-DSC analyses demonstrated changes in the LDPE sheets' functional groups, crystallinity, and in thermal properties after 120 days of incubation. The SEM and AFM images confirmed bacterial attachments, an increase in surface roughness and deformities on LDPE sheets. This study reports a bacterial consortium that can efficiently degrade the plastics and can be used in providing eco-friendly mitigation of plastic waste.

Demographic comparison of the first, second and third waves of COVID-19 in a tertiary care hospital at Jaipur, India.

Background: Coronavirus disease 2019 (COVID-19) infection in India demonstrated three peaks in India, with differences in presentation and outcome in all the three waves. The aim of the paper was to assess differences in the epidemiological, clinical features and outcomes of patients with COVID-19 presenting at a tertiary care hospital in the three waves at Jaipur, India. Methods: This was a retrospective study conducted at a tertiary care hospital at Jaipur, India. Demographic, clinical features and outcomes were compared of confirmed COVID-19 cases admitted during the first wave (16-7-2020 to 31-1-2021), second wave (16-3-2021 to 6-5-2021) and third wave (1-1-22 to 20-2-22) of the outbreak. Results: There were 1006 cases, 639 cases and 125 cases admitted during the three waves, respectively. The cases presenting in the second wave were significantly younger, with significantly higher prevalence of symptoms such as fever, cough, sore throat, nausea, vomiting, headache, muscle ache, loss of appetite and fatigue (P < 0.05). A significantly higher proportion of patients received Remdesivir in the second wave (P < 0.001). However, in the second wave, the use of low molecular weight heparin, plasma therapy, non-invasive and invasive ventilator were higher (P < 0.001). Co-morbid conditions were significantly higher in the admitted patients during the third wave (P < 0.05). Radiological scores were similar in second and third wave, significantly higher than the first wave. Lymphopenia and rise of inflammatory markers including C-reactive protein and interleukin-6 were more evident in the second wave (P < 0.001). The mean mortality, hospital stay and air-leak complications were also significantly higher in the second wave (P < 0.001). Conclusions: The second wave was more vicious in terms of symptoms, inflammatory markers, radiology, complications, requirement of ventilation and mortality. Mutation in the virus, lack of immunity and vaccination at the time point of second wave could have been the possible causes. The ferocity of the second wave has important implications for the government to formulate task forces for effective management of such pandemics.

Evaluation of Clinical Profile and Various Treatment Modalities in Oral Sub Mucous Fibrosis in North India: Our Experience.

Oral submucous fibrosis is a chronic disease affecting oral cavity and sometimes the pharynx. Etiology seems to be local irritants such as capsaicin, tobacco, areca nut and spicy foods. The main concern in this is the management of trismus and burning sensation of the oral mucosa. The aim of this study was to compare various medical treatment protocol of OSMF. 210 patients were divided randomly in 3 groups. In Group A, patients were given biweekly intralesional Hyaluronidase/Dexamethasone for 6 weeks. Group B patients were given tablet Pentoxifylline 400 mg TDS.Group C patients were given Eprisone hydrochloride. All three groups were given Lycopene 10,000 mcg for period of 6 weeks. All patients were given topical Triamcelone for local application. The examinations for mouth opening were repeated at weekly intervals for a period of 6 weeks.The most common complaint was burning sensation in 75.98% cases, difficulty in mouth opening in77.45% and difficulty in swallowing food in 61.76% cases. Group A showed improvement in 41.17% cases presenting with burning sensation followed by decreased mouth opening 39.70%. Group B showed improvement in 45.58% burning sensation, 17.64% with decreased mouth opening. Group C showed improvement in 48.52% patients having pain with spicy food, 32.35% with decreased mouth opening and 17.64% with difficulty in swallowing. We conclude that patients which received intralesional dexamethasone and hyaluronidase along with oral Lycopene showed better clinical and symptomatic improvement, and at present appears to be best non-surgical treatment.

A new approach to suppress methane emissions from rice cropping systems using ethephon.

Rice is the main staple food for more than half of the world's population. Yet, rice cultivation is subjected to criticism because of its important role in methane (CH4) emissions. Although several agronomic practices such as controlled irrigation and conservation tillage have been widely adopted to mitigate CH4 emissions from rice cultivation, the benefits gained by these practices are highly dependent on site-specific soil and climate conditions, and often offset by yield reduction. The use of plant growth regulating compounds having the potential to increase the crop yield and mitigate CH4 emissions may be an innovative approach to sustainable agriculture. Ethylene (C2H4), a plant growth regulator is known to have a strong inhibitory effect on methanogenesis. However, due to gaseous form and low water solubility, C2H4 has not been used to suppress methanogenesis in paddy fields. To develop C2H4 as a prospective soil amendment for reducing methane (CH4) emissions, ethephon (2-Chloroethylphosphonic acid), a precursor of C2H4 was tested. We found that ethephon reduced CH4 formation by 43%, similar to other well known methanogenic inhibitors (2-Bromoethanesulfonate, 2-Chlomoethanesulfonate, 2-Mercaptoethanesulfonate). However, ethephon rapidly hydrolyzed to C2H4 and methanogenic activity recuperated completely after C2H4 removal. To slow down the release of C2H4, ethephon was mixed with bio-degradable polymers such as cellulose acetate and applied to paddy soils. We found that compared with the control, the C2H4 release of ethephon slowed down to 90 days, and the CH4 emissions were reduced by 90%. The application of ethephon at lower concentrations did not significantly alter bacterial communities, their relative abundance, and the abundance of methanotrophs, but it significantly reduced archaeal communities and the relative abundance and expression level of methanogens in paddy soils. Results suggest that cellulose acetate-mixed ethephon has great promise to suppress CH4 emissions in rice paddies while ensuring sustainable yields.

Fosfomycin versus Nitrofurantoin for the Treatment of Lower UTI in Outpatients.

Introduction Fosfomycin and nitrofurantoin are increasingly being prescribed in outpatients for the oral treatment of urinary tract infection (UTI). Although ample literature is available on the in vitro sensitivity pattern of fosfomycin and nitrofurantoin in UTI cases, clinical data are scant. Methodology Voided midstream urine, collected from patients ≥ 16 years of age of both genders with suspected sign and symptoms, was plated on cystine lactose electrolyte-deficient agar. Uropathogen was defined as an organism known to be associated with the signs and symptoms of UTI with > 10 5 colony forming units/mL of urine. Antimicrobial susceptibility testing was determined by Kirby-Bauer disc diffusion method. Further, for fosfomycin, agar dilution method was also performed. Results A total of 143 patients, 47 treated with fosfomycin and 96 with nitrofurantoin, were followed for clinical outcome. The most common isolated uropathogen was Escherichia coli . In vitro susceptibility rate of uropathogens against fosfomycin and nitrofurantoin was 99.3% and 81.2%, respectively. Overall, the clinical cure rate with fosfomycin and nitrofurantoin treatment groups was 80.85% and 90.06% respectively (not statistically significant). Conclusion Fosfomycin and nitrofurantoin showed good in vitro activity against uropathogens from lower UTI and can be used for empirical therapy in our area. Multiple confounding factors may have contributed to the discrepancy between in vitro susceptibility and clinical cure, which needs to be studied further.

Deep-sea mercury resistant bacteria from the Central Indian Ocean: A potential candidate for mercury bioremediation.

Deep-sea bacteria when grown in normal environmental conditions get morphologically and genetically adapted to resist the provided culture conditions for their survival, making them a possible aspirant in mercury bioremediation. In this study, seawater samples were collected from different depths of the Central Indian Ocean and seven mercury resistant bacteria (resistant to 100 mg L-1 concentration of inorganic Hg as HgCl2) were isolated. Based on 16S rRNA gene sequencing, the identified isolates belong to the genera Pseudomonas, Bacillus and Pseudoalteromonas. The presence of the merA gene in the isolates contributes to the effective volatilization of mercury. The Inductively Coupled Plasma Mass-Spectroscopy analysis revealed that the isolates can reduce up to >80% of inorganic mercury. Moreover, Fourier Transform Infrared spectrum analysis indicates that functional groups play a key role in the mechanism of adaptation towards Hg2+ reduction. Thus, the deep-sea bacteria expressed significant tolerance and reduction potential towards ionic mercury.

Home Fortification of Complementary Foods Reduces Anemia and Diarrhea among Children Aged 6-18 Months in Bihar, India: A Large-Scale Effectiveness Trial.

BACKGROUND: Home fortification of complementary foods with multiple micronutrient powders (MNPs) is recommended to reduce child anemia in resource-poor settings. However, evidence of program effectiveness in India to guide policies and programs is lacking. OBJECTIVES: We implemented a large-scale intervention of MNPs in Bihar, India. The primary outcome was MNP consumption and change in hemoglobin concentration among children aged 6-18 mo between baseline and endline (12 mo). Secondary outcomes were change in child weight and length and infant and young child feeding (IYCF) practices (initiation, diversity, and feeding frequency). Ad hoc analyses included changes in anemia; stunting; underweight; wasting; and reported diarrhea, fever, and hospitalization. METHODS: We conducted a cluster-randomized, effectiveness trial in >4000 children within the context of ongoing health and nutrition programs implemented by CARE, India. Seventy health subcenters were randomly assigned to receive either MNPs with IYCF counseling (intervention) or IYCF counseling only (control). We used an adjusted difference-in-difference approach using repeat cross-sectional surveys at baseline and endline to evaluate impact. RESULTS: At baseline, 75% of intervention and 69% of control children were anemic and 33% were stunted. By endline, 70% of intervention households reported their child had ever consumed MNPs, and of those, 64% had consumed MNPs in the past month. Relative to control, hemoglobin concentration increased (0.22 g/dL; 95% CI: 0.00, 0.44 g/dL) and anemia declined by 7.1 percentage points (pp) (95% CI: -13.5, -0.7 pp). There was no impact on anthropometry nor IYCF practices. However, there was a decline of 8.0 pp (95% CI: -14.9, -1.1 pp) in stunting among children aged 12-18 mo. Diarrhea prevalence in the past 2 wk was reduced by 4.0 pp (95% CI: -7.6, -0.4 pp). CONCLUSIONS: Home fortification of complementary foods within a government-run program in Bihar had moderate compliance and caused modest improvements in hemoglobin and reductions in anemia and diarrhea prevalence.

Evaluation of factors influencing the trace metals in Puducherry and Diu coasts of India through multivariate techniques.

In recent years, urban and industrial development initiatives at Puducherry and Diu such as tourism, shipping, and fisheries have led to sediment contamination by trace metals, and contributed to this investigation that extended from 2016 to 2017. Strong factor loadings of Cd (0.94), Ni (0.84), Al (0.84), Cr (0.83), Co (0.82), and Fe (0.78) illustrated the variability at Puducherry, whereas Cr (0.88), Cd (0.86), Ni (0.83), Co (0.77), Cu (0.77), and Fe (0.77) showed variability at Diu. The mean rank order distribution of the top three metals in sediment was Fe > Al > Mn, which exhibited higher variability. The highest contamination factor was observed for Cd at Diu, whereas the lowest was observed at Puducherry for Al. Similarly, the risk index also exhibited considerable risk which could be attributed to Cd contamination in the sediment at Diu compared with that at Puducherry. The results obtained are essential to establish a reference for better comparison and management of the tropical environments.

CC-type glutaredoxin, OsGrx_C7 plays a crucial role in enhancing protection against salt stress in rice.

Soil salinity is one of the critical issue worldwide that adversely affect soil fertility. Salt stress significantly limits crop yield and grain quality; therefore, there is an urgent need to develop a strategy to improve salt stress tolerance. In present study, we reported that rice glutaredoxin (OsGrx_C7) plays a positive response in salt induced stress. Gene expression analysis, silencing, and overexpression of OsGrx_C7 gene were used to discover the role of OsGrx_C7 in response to salt stress. Gene expression analysis suggested that OsGrx_C7 expression was induced under salt stress and ubiquitously expressed in rice including root and shoot. The silencing of osgrx_c7 gene leads to increased sensitivity to salt stress, indicating its importance in salt stress tolerance. A gain-of-function approach showed that OsGrx_C7 may act as an important determinant in salt stress, compared with WT, and revealed higher biomass accumulation, improved root and plant growth under salt stress. Under salt stress condition, OsGrx_C7 overexpressing rice plants showed lower level of lipid peroxidation and Na+/K+ ratio, while proline accumulation, soluble sugar content and GSH/GSSG ratio was higher compared to WT. Furthermore, expression analysis suggested that OsGrx_C7 acted as positive regulator of salt tolerance by reinforcing the expression of transporters (OsHKT2;1, OsHKT1;5 and OsSOS1) engaged in Na+ homeostasis in overexpressing plants. Overall our study revealed that OsGrx_C7 emerged as a key mediator in response to salt stress in rice and could be used for engineering tolerance against salt stress in rice and other crops.
