PHYTOCHEMICAL ANALYSIS OF PORTULACA OLERACEA AND PORTULACA QUADRIFIDA EXTRACTS USING GAS CHROMATOGRAPHY–MASS SPECTROMETRY

Objective: The two plant species Portulaca oleracea and Portulaca quadrifida are commonly known as purslane and chickweed, respectively. They are typically consumed as salad or pickle. Traditional systems of medicine from Africa and China have described these plants belonging to family Portulacaceae as remedies against a host of diseases. Recent pharmacological investigations have revealed the importance of these plants as sources of antioxidants, essential fatty acids, and even antimicrobial agents. The objective of this study was phytochemical analysis and comparison of ethanolic extracts of these two species of Portulaca.Methods: The ethanolic extracts of both the species were prepared using Soxhlet extraction and were analyzed using gas chromatography coupled with mass spectrometry (GC–MS). Furthermore, the ethanolic extracts of fresh and dried whole plant of P. oleracea and seed of P. oleracea were studied.Results: The phytochemical constituents of ethanolic extracts of P. oleracea and P. quarifida were found to be quite different from one another and contained beneficial polyunsaturated fatty acids, alkaloids among other beneficial chemical species.Conclusion: The results of the study could be further used by researchers to assess the beneficial properties of both these species for in vitro and in vivo experiments

Disease Prevalence Due to Human Respiratory Syncytial Virus (HRSV) and Molecular Nature of G Gene in Different Geographical Region of India: 2005-2022

Human respiratory syncytial virus (hRSV) is the leading pediatric respiratory pathogen with high morbidity in the first year of life. The morbidity is particularly high in developing countries. it is the most common cause of infant hospitalization and causes a high burden of disease in the elderly. India is a country with vast geographical differences their unique climatic conditions. So, the prevalence of human RSV in different geographical regions is partially understood for a long time.  This review was performed by using a different search engine like Google schooler, PubMed, etc. Significant prevalence and specific RSV virus strain circulation were major keywords used for the search in the Indian pediatric population. Annual incidence rates of RSV–associated hospitalization per 1000 children were highest among infants aged 0–5 months, followed by ages 6–23 months, and lowest among children 24–59 months. hRSV was a substantial cause of hospitalization among children aged < 24 months especially those aged <6 months. Prevalence varies from 2.1% to 44% in different geographical regions. hRSV has a more broadly distributed peak timing. numerous studies of the correlation between climatic factors and hRSV incidence across latitudes found variable and inconsistent correlations between hRSV incidence & temperature, and relative humidity in different parts of the tropical region.However, genotypes ON1, NA1, GA5, and GA2 in the hRSV-A group and group hRSV-B BA, BA9, and BA12 were predominantly circulated in India

Assessment of role of genetic polymorphisms in XRCC1, XRCC2 and XRCC3 genes in cervical cancer susceptibility from a rural population: a hospital based case-control study from Maharashtra, India

Background: Cervical cancer is a major concern of health risk, moreover the leading cause of cancer causing deaths in women of rural parts of India. This study was aimed to assess the risk of cervical cancer development in association with polymorphisms in X-Ray Cross Complementing Group (XRCC1, XRCC2 and XRCC3) genes in the rural population of south-western Maharashtra. We focused to determine the frequency of polymorphisms in DNA repair genes including XRCC1 at codon (cd) 194, cd 280, cd 399, XRCC2 at cd 188 and XRCC3 at cd 241 and their plausible role in cervical cancer risk from rural parts of India.Methods: This study included 350 proven cases with cervical cancer and 400 age and sex matched controls. We used polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) to analyze the association XRCC1, XRCC2 and XRCC3 gene polymorphisms with cervical cancer development in women of South-Western Maharashtra.Results: The result from our study showed that allele frequencies of selected genes were not statistically different between the groups for XRCC1 Trp194, XRCC2 His188 and XRCC3 Met241. XRCC1 His280 (OR= 4.36; 95% CI= (3.20-5.95); p= <0.0001) and XRCC1 Gln399 (OR= 2.99; 95% CI= (1.60-5.56); p= <0.0001) genotypes significantly increased the risk of cervical cancer.Conclusions: This study indicates that polymorphisms in cd 280 of exon 9 and cd 399 of exon 10 of XRCC1 gene could play a role in modifying genetic susceptibility of individuals towards cervical cancer among women from rural Maharashtra. This case-control study suggest that selected DNA repair genes represent genetic determinants in cervical carcinogenesis along with other risk factors in the rural Indian population
