| 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 |

| 4 | Novel CMS lines in pigeonpea[Cajanus cajan(L.)Millspaugh]derived from cytoplasmic substitutions,and their effective restoration and deployment in hybrid breeding显示文摘The availability of stable cytoplasmic male sterile(CMS or A) lines coupled with a robust restoration system(R lines) is an essential prerequisite for efficient hybrid breeding.CMS-enabled hybrid technology holds immense potential to enhance the long-stagnant productivity of pigeonpea. In the present investigation, cytoplasmic substitutions were made in the nuclear backgrounds of early-maturing pigeonpea varieties or lines. Three new CMS lines(ICPL 88039 A, Pusa 992 A, and DPP 3-2A) resulted from genetic crosses involving cytoplasmic donors from A2(GT 288A) and A4(ICPA 2089) categories. In addition to visual inspection of anthers, pollen-staining techniques and scanning electron microscopy(SEM)analysis were used to confirm pollen sterility. Further, given the relevance of the plant mitochondrial genome to CMS manifestation, 25 mitochondrion-specific DNA markers were assayed on these newly developed A lines and isogenic maintainer(B) lines. DNA polymorphism between Pusa 992 A and Pusa 992 B as revealed by the nad7a_del marker confirmed the successful combination of sterilizing cytoplasm(A4) and nonrestoring nuclear background(Pusa 992). Such cytoplasm-specific DNA markers are required for A2-CMS as well. Further, to assess restoration ability, potential restorers were crossed with these CMS lines, and as a consequence, promising A × R combinations exhibiting 100%pollen fertility could be identified. In parallel, we also analyzed the inheritance patterns underlying fertility restoration using ICPL 88039A-derived F2 and BC1F1populations,and established a monogenic dominant model to explain the phenomenon of A2-CMS restoration. In summary, we report the successful development of new CMS lines and describe their effective deployment in hybrid breeding of pigeonpea. | Abhishek Bohra Rintu Jha Indra Prakash Singh Gaurav Pandey Shalini Pareek Partha Sarathi Basu Sushil Kumar Chaturvedi Narendra Pratap Singh | 2017 | The Crop Journal2017，5，1： | 1 |
