Biochemcial Changes in Powery Mildew Infected Leaves of Abelmoschus esculentus

Four types of leaf samples A1, A2 , B1 and B2 were taken from healthy and infected plants; and their free amino acids, sugars and organic acid contents were analyzed chromatographically. In case of free amino acids lysine, arginine, asparatic acid, glutamic acid, glycine and phenylatanine were found in all. There was no qualitative difference except for lysine, which gets totally consumed during the course of pathogenesis. Quantitatively was a general increase in amino acid content in B1 sample. In all three sugars were detected, they were fructose, sucrose and raffinose in all the four sample. There was a gradual decrease in the concentration of fructose and sucrose during the pathogenesis. While raffinose was maximum A1 in sample. Organic acid detected in these samples were sebacic acid, adipic acid, succinic acid, maleic acid and citric acid. Succinic acid was totally missing in B2 sample. While adipic and citric acid were maximum in B2 sample. The maximum concentration of sebacic acid was A1 sample and was least in B2. The concentration of maleic acid was maximum in A2 sample

Web Application for News Portal

News Portal provides access to all online Information about the Environment and each information source gets its dedicated area on the page for displaying information. Ne ws portal is to provide specific information, selected from newswire sit es on the Internet and also by video clips automatically extracted from TV broadcasts and as per the needs of users . The idea to made this project is to develop such web sites which will be very User friendly. This web site is working for peoples who want to share something interesting, knowledgeable, healthy, and entertainment. The traditional media rooms all around the world are fast adapting to the new age technologies. This marks the beginnin g of news portals by media houses across the globe and such new media channels give them the opportunity to reach the viewers in a shorter span of time than their print media counterparts

Study of effects of donepezil and aspirin on working memory in rats using electroconvulsive shock model

Background: Memory is the most common cognitive ability lost with dementia commonly seen in Alzheimer’s disease (AD). Donepezil was the first cholinesterase inhibitor to be licensed in UK for AD. There is preliminary evidence that aspirin decreases the risk and delays the onset of AD. Low dose aspirin users had numerically lower prevalence of Alzheimer’s dementia and had better cognitive function than non-users.Methods: Retention of conditioned avoidance response (CAR) was assessed by using repeated electroconvulsive shocks (ECS) in rats. Rats were divided into five groups: control (pretreated with distilled water), ECS (150 V, 50 Hz, with intensity of 210 mA for 0.5 sec) pretreated, combined aspirin (6.75 mg/kg) and pretreated ECS, combined donepezil (0.32 mg/kg) and pretreated ECS, combined aspirin, donepezil and pretreated ECS groups. Data were analyzed using the Chi-square test and ANOVA.Results: Findings show that administration of ECS daily for 8 days results in transient amnesia and disruption of retention of CAR. Aspirin and donepezil administration significantly increased the retention of CAR in comparison to ECS. However, aspirin failed to show an increase in the retention of CAR as compared to donepezil. The combination of the two drugs showed statistically significant increase in the retention of CAR than either of these drugs given alone.Conclusion: Neuroinflammation plays an important role in the pathophysiology of neurodegenerative disorder like AD. Combination of aspirin with donepezil increased the nootropic and neuroprotective effect of aspirin and thus may hold great clinical significance in such disorders

A greener and sustainable approach for converting polyurethane foam rejects into superior polyurethane coatings

Recycling is a crucial area of research in green polymer chemistry. Various developments in recycling are driven by Environmental concerns, interest in sustainability and desire to decrease the dependence on non-renewable petroleum based materials. Polyurethane foams [PUF] are widely used due to their light weight and superior heat insulation as well as good mechanical properties. As per survey carried Polyurethane Foam Association, 12 metric tonnes of polyurethane foam are discharged during manufacturing and/or processing and hence recycling of PUF is necessary for better economics and ecological reasons. In present study, rejects of PUF is subjected to reaction with a diethylene amine in presence of sodium hydroxide [NaOH

Adjuvant Intravesical Chemohyperthermia Versus Passive Chemotherapy in Patients with Intermediate-risk Non–muscle-invasive Bladder Cancer (HIVEC-II): A Phase 2, Open-label, Randomised Controlled Trial

Background: Adjuvant intravesical chemotherapy following tumour resection is recommended for intermediate-risk non–muscle-invasive bladder cancer (NMIBC). Objective: To assess the efficacy and safety of adjuvant intravesical chemohyperthermia (CHT) for intermediate-risk NMIBC. Design, setting, and participants: HIVEC-II is an open-label, phase 2 randomised controlled trial of CHT versus chemotherapy alone in patients with intermediate-risk NMIBC recruited at 15 centres between May 2014 and December 2017 (ISRCTN 23639415). Randomisation was stratified by treating hospital. Interventions: Patients were randomly assigned (1:1) to adjuvant CHT with mitomycin C at 43°C or to room-temperature mitomycin C (control). Both treatment arms received six weekly instillations of 40 mg of mitomycin C lasting for 60 min. Outcome measurements and statistical analysis: The primary endpoint was 24-mo disease-free survival as determined via cystoscopy and urinary cytology. Analysis was by intention to treat. Results: A total of 259 patients (131 CHT vs 128 control) were randomised. At 24 mo, 42 patients (32%) in the CHT group and 49 (38%) in the control group had experienced recurrence. Disease-free survival at 24 mo was 61% (95% confidence interval [CI] 51–69%) in the CHT arm and 60% (95% CI 50–68%) in the control arm (hazard ratio [HR] 0.92, 95% CI 0.62–1.37; log-rank p = 0.8). Progression-free survival was higher in the control arm (HR 3.44, 95% CI 1.09–10.82; log-rank p = 0.02) on intention-to-treat analysis but was not significantly higher on per-protocol analysis (HR 2.87, 95% CI 0.83–9.98; log-rank p = 0.06). Overall survival was similar (HR 2.55, 95% CI 0.77–8.40; log-rank p = 0.09). Patients undergoing CHT were less likely to complete their treatment (n =75, 59% vs n = 111, 89%). Adverse events were reported by 164 patients (87 CHT vs 77 control). Major (grade III) adverse events were rare (13 CHT vs 7 control). Conclusions: CHT cannot be recommended over chemotherapy alone for intermediate-risk NMIBC. Adverse events following CHT were of low grade and short-lived, although patients were less likely to complete their treatment. Patient summary: The HIVEC-II trial investigated the role of heated chemotherapy instillations in the bladder for treatment of intermediate-risk non–muscle-invasive bladder cancer. We found no cancer control benefit from heated chemotherapy instillations over room-temperature chemotherapy. Adverse events following heated chemotherapy were low grade and short-lived, although these patients were less likely to complete their treatment
