Report of the ICSF-BOBLME India (East Coast) workshop: implementing the FAO voluntary guidelines for securing sustainable small-scale fisheries in the context of food security and poverty eradication (SSF guidelines), 6-7 March 2015, Chennai, India

The workshop titled, ICSF-BOBLME India (East Coast) Workshop on Implementing the FAO Voluntary Guidelines for Securing Sustainable Small-scale fisheries in the Context of Food Security and Poverty Eradication (SSF Guidelines) was organized by ICSFin collaboration with BOBLME project.The workshop was the third in a series of consultations held in 2015 across the globe to promote the ownership of the SSF Guidelines among different stakeholders. In the run –up to the workshop, ICSF, with support from BOBLME conducted six consultation meetings with fishworkers and fishworker organizations along the east coast of India in January and February 2015. One hundred participants from India’s eastern coastal states of West Bengal, Odisha, Andhra Pradesh, Tamil Nadu and Puducherry, including women fishworkers, representatives of fishworker organizations, representatives from Department of Fisheries and other concerned departments at state and central level, Multilateral agencies, Inter-governmental organizations, Research Institutions met at Chennai, 6-7 March, 2015. The workshop was structured to facilitate active interaction and discussion among participants, taking into account linguistic diversity and the contextual differences of the marine and inland sectors. This publication—the proceedings of the Chennai workshop—will be useful for fishworker organizations, researchers, policymakers, members of civil society and anyone interested in fisheries and livelihoods.

The testis-specific apoptosis related gene TTL.6 underwent adaptive evolution in the lineage leading to humans

The TTL.6 gene is a member of the tubulin-tyrosine ligase (TTL) family involved in apoptosis and preferentially expressed in the testis. We sequenced the coding region and part of the introns of TTL.6 in world wide human populations and five representativ

猕猴属6个种的rDNA变异及其系统进化关系

以人28S,18S DNA为探针,用15种限制性内切酶构建了猕猴属6个种(M.mulatta、M.facsicularis、M.arctoides、M.assamensis、M.thibetana、M.nemestrina)和滇金丝猴(Rhinopithecus bieti),白颊长臂猿(Hylobates leucogenys)核糖体DNA重复单位的限制性内切酶图谱。红面猴(M.arctoides)与熊猴(M.assamensis)拥有完全相同的限制性内切酶图谱。基于内切酶图谱得到了68个信息位点并计算了各种rDNA重复型间的遗传距离。用PHYLIP version 3.5c软件包中的NEIGHBOR和RESTML程序,以滇金丝猴和白颊长臂猿为外群,构建了NJ树和最大似然树。两棵树的拓扑结构不完全一致,但恒河猴( (M.mulatta)和食蟹猴(M.facsicularis)总是位于树的基部。熊猴-红面猴(M.assamensis-M.arctoides)虽然与藏猴(M.thibetana)共享的限制性位点数更多,在NJ树上两类动物也最为接近,但在最大似然树中熊猴-红面猴却与平顶猴(M.nemestrina)聚在一起。因此,rDNA变异的数据尚不能对猕猴类动物进行有效的分组。

Purification and properties of Aspartate aminotransferase (E.C. 2.6.1.1) from skeletal muscle of Cirrhina mrigala

Aspartate aminotransferase (E.C. 2.6.1.1.) from the skeletal muscle of fresh water fish Cirrhina mrigala has been purified 40 fold by ammonium sulphate fractionation, adsorption on alumina Csub(8) gel and chromatography using DEAE-cellulose column and the properties of the purified enzyme studied. The pH optimum of the enzyme is 7.8. The Km value of aspartic acid and 2-oxoglutaric acid are found to be 2.8 x 10sub(-3) M and 1.0 x 10sub(-4) M respectively. The activity of enzyme is inhibited by p-chloromercurybenzoate, hydroxylamine hydrochloride and sodium cyanide. The inhibition by pchloromercurybenzoate is reversed by reduced glutathione, B-mercaptoethanol and cysteine. Dicarboxylic acids such as maleic acid, malic acid and succinic acid inhibit the enzyme activity. The enzyme is not activated by any of the metal ions tested and heavy metal ions such as mercury and silver strongly inhibit the enzyme activity.

用6个微卫星座位研究BMY牛和婆罗门牛的遗传多样性和群体遗传结构

对6个牛微卫星座位的遗传变异及多态性分析,以期了解BMY牛和婆罗门牛的群体遗传结构与育成情况.6个微卫星座位的多态信息含量为在0.524～0.752间,BMY牛、婆罗门牛两个群体的平均期望杂合度和观察杂合度值接近,分别为0.737 6和0.739 6,0 641 2和0.653 7,进入横交固定第二世代的BMY牛期望杂合度值较高,这与我们的育种进展相符.红安格斯的期望杂合度较低(0.460 9)接近日本和牛0.471,暗示红安格斯牛的同质性较高.

乳腺增生病p53基因第6外显子突变检测

目的 :探讨p5 3基因在乳腺癌发生早期的作用及早期诊断乳腺癌的分子病理指标。方法 :用PCR -SSCP检测36例乳腺单纯性增生、 31例不典型增生、 30例乳腺癌中p5 3基因第 6外显子突变 ,用DNA直接测序技术确定突变的碱基及其所在的密码子。结果 :乳腺单纯性增生、不典型增生、乳腺癌中p5 3基因第 6外显子的突变率分别为 0、6 5 % (2 / 31)、 13 3% (4/ 30 )。 6个点突变均为碱基替换 ,其中 4个发生于第 192密码子 (CAG→TAG) ,2个发生于第2 13密码子 (CGA→TGA) ,两者均导致多肽链合成提前终止。结论 :乳腺癌不典型增生中存在p5 3基因第 6外显子突变 ,该突变可能在乳腺不典型增生发展到乳腺癌过程中起重要作用 ,可作为早期诊断乳腺癌的辅助指标。

Studies on the toxicological effects of Asulox-40 and Emisan-6 to eggs and early life history stages of Sarotherodon mossambicus

Toxicological effects of Asulox-40 and Emisan-6 to eggs and early life history stages of Sarotherodon mossambicus were reported. 80% of egg hatching occurred in the controls, 1 p.p.m and 5 p.p.m concentrations of Asulox-40. 10 p.p.m. and 50 p.p.m. concentrations of the same toxicants had 70% and 60% hatchings while in Emisan-6 in the same concentrations the hatching were 70% and! 40%. In 100 p.p.m. concentration of both toxicants 20% incomplete hatching occurred. In Emisan-6 Lc 50 and Lc 100 values were recorded at 32 hand 96h respectively in 10 p.p.m. concentrations. In Asulox-40 the same values were recorded in 24h and 40h respectively at 50 p.p.m. concentration. The fish activity during the experimental period showed initial hyper activity. It was established that the Emisan-6 is more harmful to S. mossambicus than Asulox-40. The harmless concentrations of these chemicals were 1.2 p.p.m. for Asulox-40 and 0.6 p.p.m. for Emisan-6.
