| 1 | Significant increase in HBV, HCV, HIV and syphilis infections among blood donors in West Bengal, Eastern India 2004-2005: Exploratory screening reveals high frequency of occult HBV infection显示文摘AIM: To evaluate the prevalence of markers of hepatitis B virus (HBV) and hepatitis C virus (HCV) and human immunodeficiency virus (HIV) among blood donors in Kolkata, Eastern India for two consecutive years and to conduct a pilot study to explore the presence of HBV DNA among hepatitis B surface antigen (HBsAg) negative but anti-HBc positive blood donors. METHODS: Seroprevalence of HBsAg, anti-HCV and anti-HIV was studied among 113 051 and 106 695 voluntary blood donors screened in 2004 and 2005, respectively. Moreover, a pilot study on 1027 HBsAg negative donors was carried out for evaluating the presence of HBV DNA by PCR on HBsAg negative/anti- HBc positive donors. RESULTS: A statistically significant increase in the prevalence of HBV (1448 vs 1768, P < 0.001), HIV (262 vs 374, P < 0.001), HCV (314 vs 372, P = 0.003) and syphilis (772 vs 853, P = 0.001) infections was noted among blood donors of Kolkata West Bengal in 2005 as compared to 2004. Moreover, the exploratory study on 1027 HBsAg negative donors revealed that 188 (18.3%)of them were anti-HBc positive out of which 21% were positive for HBV DNA. CONCLUSION: The findings of this study underscore the significantly increasing endemicity of hepatitis viruses, syphilis and HIV among the voluntary blood donors of our community. The pilot study indicates a high rate of prevalence of HBV DNA among HBsAg negative/anti-HBc positive donors and thus emphasizes the need for a more sensitive and stringent screening algorithm for blood donations. | Prasun Bhattacharya Partha Kumar Chandra Sibnarayan Datta Arup Banerjee Subhashish Chakraborty Krishnan Rajendran Subir Kumar Basu Sujit Kumar Bhattacharya Runu Chakravarty | 2007 | World Journal of Gastroenterology2007，13，27： | 9 |
| 2 | Sustainability of Renewable Energy Systems with Special Reference to Ocean Thermal Energy Conversion Schemes显示文摘It was required to determine relative merits of commonly used renewable energy(RE)systems for which estimation of their individual sustainability percent achievable was chosen as the single criterion assessment tool.The methodology developed for estimating sustainability included identification of individual sustainability indices(SI)and examining the scope of sustainability percent input/kWh power generation for each of SI indices and summing them up estimating total sustainability accrued from respective RE systems.The RE systems studied included photo-voltaic(PV)cells,bio-fuels,on-shore&off-shore wind energy and OTEC schemes.Coal power plant being commercially viable was studied as the referral energy scheme.Nine SI indices identified for study included resource potential,greenhouse gas saving,influence on flora&fauna,effects on human health,land loss aspects,food and potable water security,economy evaluation,and improvement in quality of life from economic growth.Total sustainability achievable showed the highest in OTEC,followed by wind,bio-fuels and PV,respectively.SI index on quality of life showed RE schemes like OTEC&bio-fuels competing equally with coal power plant having poor sustainability with the least power generation cost;whence Hybrid OTEC showed the highest sustainability with high power production cost.Four fold approaches have been suggested for reducing power generation cost of OTEC.(i)Adopting economically viable scheme of not less than 40 MW.(ii)Heating up the working fluid with solar irradiation,terming SOTEC scheme.(iii)Saving cable laying cost,from hydrogen production utilizing the power generated.(iv)Hybridization of OTEC scheme. | Subhashish Banerjee Rahayu Binti Tasnim Fikri Zhafran Syafiqah Sathiabama T.Thirugnana Dato Ir.,A Bakar Jaafar | 2022 | Non-Metallic Material Science2022，4，2： | 0 |
