Development and Validation By RP-HPLC Method For the Estimation of Piperine Coenzyme Q10 In Bulk and Pharmaceutical Dosage Form

Safety is the fundamental principle in the provision of pharmaceutical products for health care of human being. Nutritional supplements used in medical practice are gaining considerable momentum in the world during the past decades. But this supplement is needed to be analysed before releasing in market to avoid any complications. A combination of piperine and coenzyme Q10 is used as nutritional supplement. As no analytical method has been developed for their simultaneous estimation a simple, specific, sensitive, precise and accurate RP-HPLC method was developed for the determination of CoQ10 and piperine in bulk or pharmaceutical dosage form. Coenzyme is very popular for its antioxidant property for protecting LDL from oxidation and piperine maintains cardiovascular system and increases bioavailability of coenzyme Q10. In this developed method, Waters X Bridge C8 column (250mm x 4.6mm,5μm) was used as a stationary phase and acetonitrile, tetrahydrofuran(THF), and water used in 65:32:3 (v/v) ratio as mobile phase with 1 ml/min flowrate with PDA detector detection at 275nm. The RP-HPLC was developed according to ICH guideline parameters. The retention times of Coenzyme Q10 and Piperine were 4.56 and 8.19 min respectively. The linearity ranges have lied between 4-6μg/ml, 240-360μg/ml. Correlation coefficient for both is 0.997. The present successfully validated method was applicable for the assay of piperine and coenzyme Q10 in bulk and pharmaceutical dosage forms

Analysis of fetomaternal outcome of COVID-19 antenatal mothers-initial experience

COVID-19 is an infectious disease caused by newly discovered single stranded RNA virus of Coronaviridae family. A retrospective study conducted in ABVIMS and RML hospital, Delhi in antenatal patients with COVID-19 infection detected by RT-PCR in nasopharyngeal and oral swab. It was found that patients with mean age of 27.2 years and mean gestational age of 39 weeks, mostly asymptomatic. Three patients undergone c section for obstetrical indications, while rest delivered vaginally. COVID-19 in pregnancy in small group of cases had good feto-maternal outcome but warrants further study

Genetic variability of attachment (G) and Fusion (F) protein genes of human metapneumovirus strains circulating during 2006-2009 in Kolkata, Eastern India

<p>Abstract</p> <p>Background</p> <p>Human metapneumovirus (hMPV) is associated with the acute respiratory tract infection (ARTI) in all the age groups. However, there is limited information on prevalence and genetic diversity of human metapneumovirus (hMPV) strains circulating in India.</p> <p>Objective</p> <p>To study prevalence and genomic diversity of hMPV strains among ARTI patients reporting in outpatient departments of hospitals in Kolkata, Eastern India.</p> <p>Methods</p> <p>Nasal and/or throat swabs from 2309 patients during January 2006 to December 2009, were screened for the presence of hMPV by RT-PCR of nucleocapsid (N) gene. The G and F genes of representative hMPV positive samples were sequenced.</p> <p>Results</p> <p>118 of 2309 (5.11%) clinical samples were positive for hMPV. The majority (≈80%) of the positive cases were detected during July−November all through the study period. Genetic analysis revealed that 77% strains belong to A2 subgroup whereas rest clustered in B1 subgroup. G sequences showed higher diversity at the nucleotide and amino acid level. In contrast, less than 10% variation was observed in F gene of representative strains of all four years. Sequence analysis also revealed changes in the position of stop codon in G protein, which resulted in variable length (217-231 aa) polypeptides.</p> <p>Conclusion</p> <p>The study suggests that approximately 5% of ARTI in the region were caused by hMPV. This is the first report on the genetic variability of G and F gene of hMPV strains from India which clearly shows that the G protein of hMPV is continuously evolving. Though the study partially fulfills lacunae of information, further studies from other regions are necessary for better understanding of prevalence, epidemiology and virus evolution in Indian subcontinent.</p
