RESUMEN
The impact of elevated temperature at the reproductive stage of a crop is one of the critical limitations that influence crop growth and productivity globally. This study was aimed to reveal how sowing time and changing field temperature influence on the regulation of oxidative stress indicators, antioxidant enzymes activity, soluble sugars (SS), and amino acids (AA) in Indian Mustard. The current study was carried out during the rabi 2017-2018 and 2018-2019 where, five varieties of mustard viz. Pusa Mustard 25 (PM-25) (V1), PM-26 (V2), BPR-541-4 (V3), RH-406 (V4), and Urvashi (V5) were grown under the field conditions on October 30 (normal sowing; S1), November 18 (late sowing; S2) and November 30 (very late sowing; S3) situations. The S1 and S3 plants, at mid-flowering stage, showed a significant variation in accumulation of SS (8.5 and 17.3%), free AA (235.4 and 224.6%), and proline content (118.1 and 133%), respectively, and played a crucial role in the osmotic adjustment under stress. The results showed that S3 sowing, exhibited a significant induction of the hydrogen peroxide (H2O2) (110.2 and 86.6%) and malondialdehyde (23.5 and 47.5%) concentrations, respectively, which indicated the sign of oxidative stress in plants. Interestingly, the polyphenol oxidase, peroxidase, superoxide dismutase, and catalase enzyme activities were also significantly increased in S3 plants compared to S1 plants, indicating their significant roles in ameliorating the oxidative stress. Furthermore, the concentration of fatty acid levels such as palmitic, stearic, oleic, and linoleic acids level also significantly increased in S3 plants, which influenced the seed and oil quality. The study suggests that the late sowing significantly impaired the biochemical mechanisms in Indian mustard. Further, the mustard variety V4 (RH-406) was found to be effective for cultivation as well as environmental stress adoption in Indian soils, and it could be highly useful in breeding for developing heat-tolerant genotypes for ensuring the food security.
RESUMEN
BACKGROUND: Ministry of Health and Family Welfare has developed National Quality Framework to assess the quality of services for improvement and helps in certification of facilities, while Kayakalp was launched to promote cleanliness and hygiene in public health facilities. OBJECTIVE: The objective of the study is to assess if Kayakalp implementation within the public health facilities supports quality certification of health facilities. METHODS: A retrospective study was designed to gather data for 32 quality-certified district hospitals under National Quality Assurance Standards (NQAS) between May 2015 and April 2018 by reviewing records. Certification criteria and their external assessment checklist under NQAS and Kayakalp program for district hospitals were extracted from their respective states. External assessment score of all district hospitals under study was entered and analyzed using Statistical Package for the Social Sciences version 22 for Pearson's correlation analysis and MS Excel 2016 for statistical analysis. RESULTS: Pearson's correlation coefficient was 0.217, which means that Kayakalp implementation has less significance on the quality certification of public health facilities to NQAS. A scatter chart was plotted which depicts nonlinear relationship between dependent and independent variable. CONCLUSION: Overall impact of implementation of Kayakalp initiative on quality certification of public health facilities to NQAS was significantly low; however, this could be due to less weightage given to the checkpoints in NQAS as compared to in NQAS.
RESUMEN
In this present work, laser welding experiments were carried out on 1 mm thin Ti6Al4V sheets using a low power Nd-YAG laser machine without using any filler wire and without edge preparation of welding specimens. The influence of different major process control parameters such as welding speed and power on the yield parameters like temperature field, weld bead geometry, microstructure, and mechanical properties are critically investigated. Experimental results are compared in detail with the simulated results obtained using a commercial 3D finite element model. In the simulation model, temperature-dependent thermal and mechanical properties of plates were considered. The temperature readings were recorded with the aid of K type thermocouples. Forced convection has been assumed near weld zone region because of the movement of the shielding gas. Appreciable agreement is found between the experimental and the simulated temperature fields in most of the cases with few exceptions. These deviations on few occasions may be due to the presence of uncertainties inherently present in the experimental domain and uncertainties in the subsequent temperature sensing techniques by the thermocouples. In addition, annealing has been done at 950 °C, 980 °C, and 1010 °C for one selected parameter (192 W, 6 mm/s). The tensile strength of the samples annealed at 980 °C has been found to be 1048 MPa and it is 3% to 4% higher than that of the usual welded samples.
RESUMEN
BACKGROUND: Personal hygiene plays a major role to promote healthy life. This study was performed to assess the current level of knowledge and practicing behavior in regard to hand washing, bathing, tooth brushing, and taking care of nail and hair. MATERIALS AND METHODS: A cross-sectional descriptive study was conducted on 800 students of Lucknow district. All the students were interviewed with a structured questionnaire (pretest). A visual display of good and bad personal hygiene was shown on projector and explained the benefits of good personal hygiene behavior. Again, structured questionnaire was given (posttest). RESULTS: Most of the students belonged to the 10-12 years age group. The knowledge of the students regarding general body cleanliness was 87.5% in posttest as compared to 53.8% in pretest. Keeping the hair well-trimmed was considered as a part of personal hygiene by 38.0% of students. Knowledge about eating less food in diarrhea was positive in 80% of students. Only 12.5% of students accepted that diarrhea can kill children (pretest) while 100% (posttest) children were aware of this fact. Practice regarding change of clothes was on alternate day in 79.5% of students. Most of the students were found washing their hair once a week (72.5%) and 70% students were washing hands before meal. CONCLUSION: Overall trend of knowledge and practice about personal hygiene was in poor condition among students at the time of pretest. Posttest results were highly satisfactory.
RESUMEN
A new continuous fibroblast cell line was established from the muscle tissue of healthy juvenile Danio rerio (Zebrafish) through explant method. Fish cell lines serve as useful tool for investigating basic fish biology, as a model for bioassay of environmental toxicant, toxicity ranking, and for developing molecular biomarkers. The cell line was continuously subcultured for a period of 12 months (61 passages) and maintained at 28 °C in L-15 medium supplemented with 10% FBS and 10 ng/mL of basic fibroblastic growth factor (bFGF) without use of antibiotics. Its growth rate was proportional to the FBS concentration, with optimum growth at 15% FBS. DNA barcoding (16SrRNA and COX1) was used to authenticate the cell line. Cells were incubated with propidium iodide and sorted via flow cytometry to calculate the DNA content to confirm the genetic stability. Significant green fluorescent protein (GFP) signals confirmed the utility of cell line in transgenic and genetic manipulation studies. In vitro assay was performed with MTT to examine the growth potential of the cell line. The muscle cell line would provide a novel invaluable in vitro model to identify important genes to understand regulatory mechanisms that govern the molecular regulation of myogenesis and should be useful in biomedical research.

INTRODUCTION: The current epidemiological data and meta-analyses indicate a bidirectional association between depression and metabolic syndrome (MetS). AIMS: To assess the prevalence of metabolic syndrome and obesity in drug naïve patients (in current episode) having Recurrent Major Depressive Disorder and Bipolar Depression. METHOD: This was a single point cross sectional observational study that involved administration of diagnostic and assessment tools and blood investigations. Recruitment for the study was done from a period of September 2008 to august 2009. RESULTS: The prevalence of MetS was significantly more in the depression group when compared to healthy controls. The Bipolar depression group had 24% prevalence and recurrent depression group had 26% prevalence as opposed to none in the control group. The prevalence of MetS did not differ significantly amongst the both depression groups. Presence of central obesity was significantly more in the recurrent depression (30%) and Bipolar depression (24%) as compared to controls (8%). There was no statistically significant difference between the two depression subgroups. DISCUSSION: Our study adds to the mounting evidence that links the presence of depression and metabolic syndrome. As we had ensured a drug free period of at least 3 months, the findings in our study indicate that the metabolic syndrome observed in our study is independent of drug exposure. CONCLUSIONS: This study demonstrated significantly more incidence of metabolic syndrome and central obesity in patients of depression than age and sex matched controls.
RESUMEN
BACKGROUND: At present, in a medical school, students are taught in different departments, subject-wise, without integration to interrelate or unify subjects and these results in compartmentalization of medical education, with no stress on case-based learning. Therefore, an effort was made to develop and adopt integrated teaching in order to have a better contextual knowledge among students. METHODOLOGY AND IMPLEMENTATION: After the faculty orientation training, four "topic committees" with faculty members from different departments were constituted which decided and agreed on the content material to be taught, different methodologies to be used, along with the logical sequencing of the same for the purpose of implementation. Different teaching methodologies used, during the program, were didactic lectures, case stimulated sessions, clinical visits, laboratory work, and small group student's seminar. RESULTS: After the implementation of program, the comparison between two batches as well as between topics taught with integrated learning program versus traditional method showed that students performed better in the topics, taught with integrated approach. Students rated "clinical visits" as very good methodology, followed by "case stimulated interactive sessions." Students believed that they felt more actively involved, and their queries are better addressed with such interactive sessions. CONCLUSION: There is a very good perception of students toward integrated teaching. Students performed better if they are taught using this technique. Although majority of faculty found integrated teaching, as useful method of teaching, nevertheless extra work burden and interdepartmental coordination remained a challenging task.
RESUMEN
Background. CDRI 97/78 has shown efficacy in animal models of falciparum malaria. The present study is the first in-human phase I trial in healthy volunteers. Methods. The study was conducted in 50 healthy volunteers in a single, ascending dose, randomized, placebo-controlled, double blind design. The dose ranges evaluated were from 80 mg to 700 mg. Volunteers were assessed for clinical, biochemical, haematological, radiographic, and electrocardiographic parameters for any adverse events in an in-house facility. After evaluation of safety study results, another cohort of 16 participants were administered a single oral dose of 200 mg of the drug and a detailed pharmacokinetic analysis was undertaken. Results. The compound was found to be well tolerated. MTD was not reached. The few adverse events noted were of grade 2 severity, not requiring intervention and not showing any dose response relationship. The laboratory and electrocardiographic parameters showed statistically significant differences, but all were within the predefined normal range. These parameters were not associated with symptoms/signs and hence regarded as clinically irrelevant. Mean values of T 1/2, MRT, and AUC0-∞ of the active metabolite 97/63 were 11.85 ± 1.94 h, 13.77 ± 2.05 h, and 878.74 ± 133.15 ng·h/mL, respectively Conclusion. The novel 1,2,4 trioxane CDRI 97/78 is safe and will be an asset in malarial therapy if results are replicated in multiple dose studies and benefit is shown in confirmatory trials.
RESUMEN
BACKGROUND: Hypertension is the most common disorder which is encountered in outdoor patients. The existing data suggests that there is an increase in the prevalence of pre-hypertension and hypertension in India. The prevalence of hypertension will increase even further, unless broad and effective preventive measures are implemented. The main objective of this study was to find out the prevalence of hypertension amongst the adult outdoor patients of an urban health centre of Lucknow district. MATERIALS AND METHODS: This observational, Out Patients Department based study involved a survey on 306 male and 1203 female respondents who were aged 18 years, who attended the Urban Health Training Centre of the Department of Community Medicine, Era's Lucknow Medical College and Hospital, Lucknow, India. A structured, pretested schedule was used to collect the data with regards to the demographic characteristics and the blood pressure pattern. The Chi- square test and ANOVA were used to analyze the data. RESULTS: The prevalence of hypertension was found to be 44.46%. The proportion of hypertension showed an increasing trend with age. The mean systolic as well as diastolic blood pressure patterns were found to be higher, with an increase in age. CONCLUSION: Hypertension was found to be highly prevalent among the outdoor patients of an urban health centre of Lucknow. An early detection of hypertension can be facilitated by periodically screening people regularly.
RESUMEN
High temperature (>30 °C) at the time of grain filling is one of the major causes of yield reduction in wheat in many parts of the world, especially in tropical countries. To identify quantitative trait loci (QTL) for heat tolerance under terminal heat stress, a set of 148 recombinant inbred lines was developed by crossing a heat-tolerant hexaploid wheat (Triticum aestivum L.) cultivar (NW1014) and a heat-susceptible (HUW468) cultivar. The F(5), F(6), and F(7) generations were evaluated in two different sowing dates under field conditions for 2 years. Using the trait values from controlled and stressed trials, four different traits (1) heat susceptibility index (HSI) of thousand grain weight (HSITGW); (2) HSI of grain fill duration (HSIGFD); (3) HSI of grain yield (HSIYLD); and (4) canopy temperature depression (CTD) were used to determine heat tolerance. Days to maturity was also investigated. A linkage map comprising 160 simple sequence repeat markers was prepared covering the whole genome of wheat. Using composite interval mapping, significant genomic regions on 2B, 7B and 7D were found to be associated with heat tolerance. Of these, two (2B and 7B) were co-localized QTL and explained more than 15 % phenotypic variation for HSITGW, HSIGFD and CTD. In pooled analysis over three trials, QTL explained phenotypic variation ranging from 9.78 to 20.34 %. No QTL × trial interaction was detected for the identified QTL. The three major QTL obtained can be used in marker-assisted selection for heat stress in wheat.

This work aims at optimal composting of agro-wastes like sugarcane bagasse, wood straw and soya husk. A mixture of these substances along with small quantity of food waste as the seed was composted aerobically and carbon dioxide evolved was determined experimentally using a composting system comprising aerobic digester, operating in near-optimal conditions with regard to adequacy of oxygen and temperature in the system. During aerobic composting of agro-waste carbon dioxide is produced due to degradation of different carbon fractions in the substrate. Carbon dioxide production rate, which is a measure of bacterial/fungal activity in composting systems, can be related to various process parameters like different carbon fractions present in the substrate and their reaction rates, progress and termination of compost phenomenon and stabilization of organic matter. This gives a balanced compromise between complexity of mathematical model and extensive experimentation, and can be used for determining optimum conditions for composting.

Effluents of three different tanneries (T-1, T-2, & T-3) were investigated to isolate and scrutinize antibiotic, chromate and salinity resistant bacteria. Total 18 isolates of 9 different bacterial genera were screened out and identified; some strains established in all effluents. Amongst the three effluents tested; T-1 exhibited largest population of all isolates compared to T-2 and T-3 effluents. The T-1 effluent contained largest 4.4 x10(6) cfu/ml population of Pseudomonas aeruginosa followed by 3.9 x10(6) cfu/ml in T-2 effluent. The lowest 0.7 x10(6) cfu/ml count of Aeromonas spp. was recorded in T-3 effluent. Furthermore, antibiotic susceptibility tests were performed with 7 antibiotics which include ampicillin, sulfafurazole, ciprofloxacin, norfloxacin, tetracycline and amikacin. Three strains of P. aeruginosa and one strain of Escherichia coli deserved as multiple drug resistant (MDR). The P. aeruginosaT-3 and E. coliT-1 showed strongest MDR feature for 5 antibiotics. The response of chromate (50, 100, 200, 250 and 300 µg/ml) and NaCl concentrations (20, 40, 60 and 80 g/l) was incredible for 4 MDR isolates. Nearly each strain showed tolerance up to 300 µg/ml of chromate and 80 g/l of NaCl. The P. aeruginosaT-1, P. aeruginosaT-2, P. aeruginosaT-3 and E. coliT-1 were most tolerant isolates. Plasmid profiling of resistant strains was conducted with agarose gel electrophoresis. As consequence, plasmids from two strains of P. aeruginosa and E. coliT-1 represented different bands. At least for confirmation of plasmids nature; these were transformed and transformants were screened on medium having antibiotics. The study of plasmid transformation has confirmed the plasmid mediated resistance in isolates.

Actin filament binding by the focal adhesion (FA)-associated protein talin stabilizes cell-substrate adhesions and is thought to be rate-limiting in cell migration. Although F-actin binding by talin is known to be pH-sensitive in vitro, with lower affinity at higher pH, the functional significance of this pH dependence is unknown. Because increased intracellular pH (pH(i)) promotes cell migration and is a hallmark of metastatic carcinomas, we asked whether it increases FA remodeling through lower-affinity talin-actin binding. Talin contains several actin binding sites, but we found that only the COOH-terminal USH-I/LWEQ module showed pH-dependent actin binding, with lower affinity and decreased maximal binding at higher pH. Molecular dynamics simulations and NMR of this module revealed a structural mechanism for pH-dependent actin binding. A cluster of titratable amino acids with upshifted pK(a) values, including His-2418, was identified at one end of the five-helix bundle distal from the actin binding site. Protonation of His-2418 induces changes in the conformation and dynamics of the remote actin binding site. Structural analyses of a mutant talin-H2418F at pH 6.0 and 8.0 suggested changes different from the WT protein, and we confirmed that actin binding by talin-H2418F was relatively pH-insensitive. In motile fibroblasts, increasing pH(i) decreased FA lifetime and increased the migratory rate. However, expression of talin-H2418F increased lifetime 2-fold and decreased the migratory rate. These data identify a molecular mechanism for pH-sensitive actin binding by talin and suggest that FA turnover is pH-dependent and in part mediated by pH-dependent affinity of talin for binding actin.

Populations in North India depend on a number of vegetable crops of which Amaranthus spp. is the most important since it is the only crop available in the hot summer months when no other foliage crop grows in the field. However, reports on mineral composition of leaves are rare with absolutely no information on the qualitative improvement of foliage yield with special reference to minerals. Studies on correlation among the minerals as well as with yield and leaf attributes are also lacking. Hence, we report the proximate mineral composition in 30 strains of A. tricolor along with some suggestions for qualitative improvement of the foliage yield with reference to minerals. Our study showed that vegetable amaranth is a rich source of minerals like calcium (1.7 +/- 0.04 g/100 g), iron (1233.8 +/- 50.02 mg/kg), and zinc (791.7 +/- 28.98 mg/kg). The heritability estimates were high for most of the traits, with potassium and calcium showing high values, while comparatively lower values were recorded for magnesium and nickel. Nickel was the only mineral that showed positive correlation with all the minerals, as well as with leaf size and foliage yield. Zinc showed strong positive relationship with iron (0.66**) and manganese (0.74**), and was the only mineral exhibiting significant positive association with foliage yield. This study would be of use in enhancement of selected minerals in different regions according to local preferences and nutrient deficiency prevalent among the populations.

BACKGROUND: Brahmi (Bacopa monniera) is a traditional Indian medicinal plant which causes multiple effects on the central nervous system. The standardized extract of this plant has shown enhanced behavioural learning in preclinical studies and enhanced information processing in healthy volunteers. AIM: To study the efficacy of standardized Bacopa monniera extract (SBME) in subjects with age-associated memory impairment (AAMI) without any evidence of dementia or psychiatric disorder. METHODS: A double-blind, placebo-controlled randomized study design was employed. The subjects received either 125 mg of SBME or placebo twice a day for a period of 12 weeks followed by a placebo period of another 4 weeks (total duration of the trial 16 weeks). Each subject was evaluated for cognition on a battery of tests comprising mental control, logical memory, digit forward, digit backward, visual reproduction and paired associate learning. RESULTS: SBME produced significant improvement on mental control, logical memory and paired associated learning during the 12-week drug therapy. CONCLUSION: SBME is efficacious in subjects with age-associated memory impairment.
RESUMEN
Phytoterpenoid isolated from Artabotrytis odoratissimus inhibited spore germination of some plant pathogenic as well as saprophytic fungi e.g. Alternaria alternata, A. solani, Cercospora sp., Curvularia maculans, C. pennisetti, Fusarium udum, Helminthosporium echinochlova, H. frumentacie, H. penniseti and Ustilago cynodontis. In Curvularia maculans and H. frumentacie, spore germination was completely inhibited at 2000 ppm. However, Curvularia maculans and C. pennisetti showed considerable sensitivity to this chemical even at 500 ppm.
RESUMEN
In addition to providing a regulated linkage between the membrane and the actin cytoskeleton, ezrin participates in signal transduction pathways. Here we describe that expression of the ezrin Y145F mutant delays epithelial cell spreading on fibronectin by inhibiting events leading to FAK activation. The defect in spreading was rescued by the overexpression of catalytically functional Src. We demonstrate that ezrin Y145 is phosphorylated in A431 cells stimulated with epidermal growth factor (EGF) and in v-Src-transformed cells. Moreover in cells devoid of Src, SYF-/- fibroblasts, ezrin Y145 phosphorylation could only be detected upon the introduction of an active form of Src. The phosphorylation of ezrin at Y145 required prior binding of the Src SH2 domain to ezrin. Our results further show that Src activity influences its binding to ezrin and a positive feedback mechanism for Src-mediated Y145 phosphorylation is implied. Interestingly, cells expressing ezrin Y145F did not proliferate when cultured in a 3D collagen gel. Collectively, our results demonstrate a key signaling input of Src-dependent ezrin phosphorylation in adhesion-mediated events in epithelial cells.

The integral membrane proteins (IMP's) of promastigotes of two virulent strain of Leishmania (L.) donovani Dd8 and Leishmania (L.) infantum LV9 and one avirulent viscerotropic strain Leishmania tropica UR6 were extracted by phase separation technique using a non-ionic detergent "Triton X-114". This detergent is homogeneous at 0 degrees C but divides in an aqueous phase and a detergent phase at above 20 degrees C. The phase partition resulted in solubilisation of hydrophilic proteins in aqueous phase, and IMP's with an amphiphilic nature were recovered in the detergent phase. The strain wise quantitative recovery rates of IMP's were estimated. These proteins were purified by chill methanol centrifugation and used as vaccinogen, alone or in combination with adjuvant against L. donovani challenge in hamster model. Among all the combinations, hamsters immunised with IMP of L. donovani (Dd8) in combination with CFA resulted in 75% parasite inhibition in spleen (P <0.001), however, 61.14% (P <0.001) and 77.60% (P <0.001) parasitic inhibition was achieved in liver and bone marrow respectively as compared to their unvaccinated counter part. Similar combinations with UR6 and LV9 strain inhibited the parasite establishment up to 65.12% (P <0.001) and 66.87% (P <0.001), respectively on splenic site. The specific IgG level against (Dd8 strain) soluble leishmania promastigote antigen was monitored at different stages by enzyme linked immunosorbent assay (ELISA) corresponds to the level of parasitic establishment. Similar observations were made in cases of LV9 and UR6 strains. However, significant lymphoproliferative response to IMPs of Dd8 strain (SI 3.5-4.9, P <0.001) was noticed in all IMP + CFA vaccinated animals. Thus, this study will provide a lead for more manipulative trials to develop a subunit vaccine against the fatal disease.

OBJECTIVE: The antifungal activity of various solvent extracts (such as ether, chloroform, ethyl acetate and ethyl alcohol) of the plant Phyllanthus amarus against dermatophytic fungi Microsporum gypseum was observed. METHOD: Antifungal bioassay in terms of reduction in weight, colony diameter and sporulation of the target fungal colony was carried out using Broth Dilution method. Results Root part of the plant, extracted in various organic solvents did not show any noticeable antifungal activity. The percentage inhibition observed in different solvent extracts of aerial part was found as reduction in weight: chloroform [50.3%], ethyl acetate [27.7%] and ethyl alcohol [12.1%], reduction in colony diameter: chloroform [53.4%], ethyl acetate [31.4%] and ethyl alcohol [15.0%] and reduction in sporulation: maximum inhibition in chloroform extract, at test concentration of 4000 ppm at incubation period of 8 days. CONCLUSION: Chloroform fraction of the aerial part of the plant P. amarus shows significant inhibitory effect against dermatophytic fungi M. gypseum and requires chemical characterization for its bioactive principle.
