Drug utilization pattern of antimicrobials in OPD of ENT in teaching hospital

Background: A drug utilization study may be helpful to identify the problems, suggest the remedial measures and promote rational use. Antimicrobials are commonly used to treat infections caused by bacteria, viruses, protozoa and fungi, evidently require huge prescriptions in India.Methods: A prospective, observational study was carried out for a period of four months from February to May 2019 in the Department of ENT (OPD) at NRI Medical College and General Hospital. Prescriptions were collected randomly from around 300 patients attending the ENT outpatient department after obtaining informed consent. The data were collected in the predesigned proforma for analysis.Results: 300 ENT patients were selected for the study, 62% were male and 38% were female. Out of 300 patients 190 ear disorders, 50 nasal, and 60 throat infections. Antimicrobial therapy were most commonly instituted in ear diseases (67.66%), nose (16.95%) and throat (15.37%) respectively. The most commonly used agents were amoxicillin with clavulanic acid- n=295, cefixime- n=1260, gentamicin- n=200, ciprofloxacin- n=157, azithromycin- n=199, nitroimidazoles (metronidazole- n=111).Conclusions: Cefixime and amoxicillin+clavulanic acid combination was the most commonly prescribed antibiotic in our study. Interventions to rectify the use of brand names are necessary to promote rational drug use. An antibiotic policy has to be developed for the doctors in treating infections so that rationality in using the antibiotics will be developed and the occurrence of antibiotic resistance can be reduced

Nonlinear optical studies of sodium borate glasses embedded with gold nanoparticles

Optical glasses possessing large third-order optical nonlinear susceptibility and fast response times are promising materials for the development of advanced nonlinear photonic devices. In this context, gold nanoparticle (NP)-doped borate glasses were synthesized via the melt-quench method. The nonlinear optical (NLO) properties of thus prepared glasses were investigated at different wavelengths (i.e., at 532 nm using nanosecond pulses, at 750 nm, 800 nm, and 850 nm wavelengths using femtosecond, MHz pulses). At 532 nm, open aperture (OA) Z-scan signatures of gold NP-doped borate glasses demonstrated reverse saturable absorption (RSA), attributed to mixed intra-band and interband transitions, while in the 750850 nm region, the OA Z-scan data revealed the presence of saturable absorption (SA), possibly due to intra-band transitions. The NLO coefficients were evaluated at all the spectral regions and further compared with some of the recently reported glasses. The magnitudes of obtained NLO coefficients clearly demonstrate that the investigated glasses are potential materials for photonic device applications

Human protein reference database—2006 update

Human Protein Reference Database (HPRD) () was developed to serve as a comprehensive collection of protein features, post-translational modifications (PTMs) and protein–protein interactions. Since the original report, this database has increased to >20 000 proteins entries and has become the largest database for literature-derived protein–protein interactions (>30 000) and PTMs (>8000) for human proteins. We have also introduced several new features in HPRD including: (i) protein isoforms, (ii) enhanced search options, (iii) linking of pathway annotations and (iv) integration of a novel browser, GenProt Viewer (), developed by us that allows integration of genomic and proteomic information. With the continued support and active participation by the biomedical community, we expect HPRD to become a unique source of curated information for the human proteome and spur biomedical discoveries based on integration of genomic, transcriptomic and proteomic data
