Role Of Bacteria And Their Enzymes In Degradation Of Azo Dyes: A Review

The azo dyes are aromatic compounds containing azo (–N=N–) groups enabling them to be potent in absorbing visible spectrum light. These are considered to be electron-deficient toxic effluents due to the non-biodegradability function allowed through azo linking bonds. The azo bonds make the concerned dye resistant for preventing its degradation by enzymes produced by microorganisms. The most potent enzyme till now found for azo dye reduction is a group of reductase enzyme called azoreductase that facilitate the reaction using some suitable cofactors. Several microorganisms, especially the bacteria are readily used for successful azoreductase enzymes activity in azo dye decolourization. These enzymes are mostly isolated from bacterial cells and are found to be highly effective in case of partial or complete removal of azo dyes. Thus, the reason for the current review relies on a comprehensive systematization of various bacteria those are responsible for production of azoreductase enzymes and their application in azo dye decolourization. This review also compiles different bacterial enzymes responsible for degradation of the toxic azo dyes

SOCIAL INCLUSION OF CHILDREN DIAGNOSED WITHAUTISM SPECTRUM DISORDER IN INDIA: A LITERATURE REVIEW

Autism Spectrum Disorder is a neurodevelopmental disorder defined by insufficiency in social communication and social interaction skills and restricted and repetitive patterns of behavior. The aim of this research was to analyze empirical studies on inclusion of children with Autism in India over the past 20 years and then propose recommendations for future research. A systematic process was used to conduct the review which included identifying the data source, assessing the quality of our studies, and drawing analysis of our findings. The result included different stakeholder’s perspectives which were parents and teachers.   Article visualizations

Ecofriendly Synthesis of DHPMs using Copper-based Nano catalysts and Evaluation of Antibacterial Activity

A new catalytic approach has been developed under microwave irradiation for the multicomponent reaction (MCR) of aromatic aldehydes, urea/thiourea and ethylacetoacetate to give corresponding dihydropyrimidinones (DHPMs) by using CuFe2O4/CuO-CeO2 nanoparticles (NPs) as heterogeneous and recyclable catalysts. 3, 4-Dihydropyrimidin-2(1H) ones/thiones are synthesized in higher yields (80-95 %) and short reaction time (8−10 minutes) at 245 Watts. It is applicable for both types of aromatic aldehydes containing EWS as well as EDS. Further, the synthesized compounds were evaluated for antibacterial activity against E. coli, B. subtilis, B. megaterium, and P. vulgaris. Among the compounds tested, ethyl-6-methyl-2-oxo-4-(4-chlorophenyl)-1,2,3,4-tetrahydropyrimidin-5-carboxylate, 4c showed response against B. subtilis, B. megaterium, and P. vulgaris and ethyl-6-methyl-2-oxo-4-(4-fluorophenyl)-1,2,3,4-tetrahydropyrimidin-5-carboxylate, 4h showed –ve response against E. coli, B. subtilis, B. megaterium, and P. vulgaris

To Identify Drug-Drug Interaction in Cardiac Patients in Tertiary Care Hospitals

The potential for drug-drug interactions (pDDIs) is higher with cardiac medications, and reports of pDDIs in cardiovascular patients are more common. Multimorbidity, a greater number of drugs prescribed, longer hospital stays, complexity of disease, physiological changes with advancing age or conditions like renal failure, shock, hepatic disease like cirrhosis or acute viral hepatitis, stages of disease, and the influence of heart disease on drug metabolism make patients with CVD especially susceptible to DDIs. Our research found that pDDIs occurred at a much higher rate than expected in the Cardiology Division. Incidence of pDDIs was observed to rise with age, polypharmacy, and duration of hospital stay; pDDIs were also more common in males than females. Most of the interactions were of a pharmacodynamic character and were considered to be quite serious. Most pDDIs involved aspirin and clopidogrel, then aspirin and enalapril, and finally enalapril and enalapril. The surveillance of pDDIs in cardiac inpatients may benefit from the creation of such a database in hospitals

Posterior migration of Ahmed glaucoma valve tube in a patient with Reiger anomaly: a case report

BACKGROUND: To describe, a yet non-documented complication of GDI surgery (glaucoma drainage incision surgery) - anterior to posterior segment migration of Ahmed Glaucoma Valve (AGV) tube. CASE PRESENTATION: We report a young 9 year old boy, diagnosed with refractory glaucoma with Reiger anomaly. History included of poor vision in both eyes, left more than right with glare since childhood. He underwent GDI surgery with AGV implantation following which he developed posterior migration of AGV tube. The detailed ocular history, ophthalmic findings, clinical course, surgical management and development of the posterior tube migration is discussed. CONCLUSION: Posterior Migration of AGV tube has yet not been described. Also there is a role of expectant management of the complication in this case as evidenced by the benign course of events

Comparison of biochemical and anthropometric parameters in complicated and uncomplicated severe acute malnutrition among children aged 6 to 59 months: a cross-sectional study

Aim: The frequency of severe acute malnutrition (SAM) is the highest in India. Although it should receive more attention, severe anemia is one of the comorbidities that increases mortality in children who are severely undernourished. In SAM children, the liver function test (LFT), kidney function test (KFT), and complete blood count (CBC) are deranged, but their correlation with the prognosis is not well defined. The aim was to describe the anthropometric assessment and biochemical profile of children with SAM. Methods: This cross-sectional cohort study was performed at the Departments of Paediatrics and Biochemistry at G.S.V.M. Medical College, Kanpur, and at the Department of Biotechnology at Amity University Rajasthan, Jaipur. One hundred and six patients with SAM were enrolled; 53 were grouped as complicated SAM (Group 1) (dehydration and severe dehydration) and 53 were diagnosed as non-complicated SAM (Group 2). Results: Group II had significantly higher mean values for height, weight, mid-upper arm circumference (MUAC), head circumference, and body mass index (BMI) for age percentile compared to Group I, with P-values of 0.001. Group I had a significantly lower level of hemoglobin (8.86 g/dL ± 2.21 g/dL) compared to Group II (10.0 g/dL ± 1.83 g/dL) with a P-value of 0.003. The difference in the frequency of anemia between the groups was statistically significant, with a P-value of 0.026. Anemia significantly increased the risk of complicated SAM with an odds ratio of 2.60 [95% confidence interval (CI), 1.07–6.31, P = 0.001]. Conclusions: This study suggests that there may be a significant relationship between anemia and the development of complications in high-risk children with SAM

Homeostatic control of stearoyl desaturase expression via patched-like receptor PTR-23 ensures the survival of C. elegans during heat stress

Organismal responses to temperature fluctuations include an evolutionarily conserved cytosolic chaperone machinery as well as adaptive alterations in lipid constituents of cellular membranes. Using C. elegans as a model system, we asked whether adaptable lipid homeostasis is required for survival during physiologically relevant heat stress. By systematic analyses of lipid composition in worms during and before heat stress, we found that unsaturated fatty acids are reduced in heat-stressed animals. This is accompanied by the transcriptional downregulation of fatty acid desaturase enzymes encoded by fat-1, fat-3, fat-4, fat-5, fat-6, and fat-7 genes. Conversely, overexpression of the Δ9 desaturase FAT-7, responsible for the synthesis of PUFA precursor oleic acid, and supplementation of oleic acid causes accelerated death of worms during heat stress. Interestingly, heat stress causes permeability defects in the worm’s cuticle. We show that fat-7 expression is reduced in the permeability defective collagen (PDC) mutant, dpy-10, known to have enhanced heat stress resistance (HSR). Further, we show that the HSR of dpy-10 animals is dependent on the upregulation of PTR-23, a patched-like receptor in the epidermis, and that PTR-23 downregulates the expression of fat-7. Consequently, abrogation of ptr-23 in wild type animals affects its survival during heat stress. This study provides evidence for the negative regulation of fatty acid desaturase expression in the soma of C. elegans via the non-canonical role of a patched receptor signaling component. Taken together, this constitutes a skin-gut axis for the regulation of lipid desaturation to promote the survival of worms during heat stress.<br/
