New High Resolution Pollen Records from Two Lakes in Xizang (Tibet)

Studies on the pollen from cores of Lake Hidden (29~48.77' N, 92~22.37' E) and Ren Co (30%3.97'N, 96~40.97'E) in Southeast Xizang (Tibet) showed climatic changes and the evolution of vegetation since the last Glacial Maximum (LGM). Before 16 ka BP pollen assemblages were dominated by Chenopodiaceae (20% -50% ) and Artemidis (10% ~ 30% ) and pollen influx values were very low from Lake Ren Co in Basu county. The vegetation around the lake was probably a desert-steppe during the LGM. The data also suggest that the climate in the Basu area was cold and dry during the LGM and the last glacial time. The mean annual temperature was probably 4 ~ 6 ℃ colder than the present, and the mean annual precipitation was only 250 mm, about 40% of the present. The Southwest monsoon became stronger from 12 ka BP to 6 ka BP reaching its acme by 7 ka BP, but weakened gradually from 5 ka BP to the present. The paleovegetation was dominantly forest or forest-meadow around Lake Hidden and Ren Co during the 9.2 ~ 5 ka BP. The mean temperature in January was probably 2 ~ 3 ℃ higher than the present, and the mean annual precipitation was 100 mm more than the present. The timing of vegetational and climatic changes based on pollen records generally supports the results of global climatic-model experiments that predict a strengthened monsoon system during the early to middle Holocene followed by a weakened monsoon system.

中国西藏发现类三角蚌类祖先闯入非海相领域的证据（英文）北大核心CSCD

新发现的双壳类化石命名为Baxoitrigonia baxoiensis gen. et sp. nov.,产地为藏东八宿林卡家东,化石产于景星动物群之下的拉贡塘组下段,同层位有菊石和其他海相双壳类,时代为晚侏罗世Tithonian期;化石的外部特征很接近于三角蛤类Iotrigonia属,但前闭肌痕特征又相似于类三角蚌类,被认为是三角蛤类闯入非海相领域后演变成类三角蚌类的产物。此发现提供了生物和地层两方面的直接证据,证明非海相类三角蚌类(Trigonioidoidea超科)起源于海相三角蛤类(Trigoniida目),而不是起源于珠蚌类(Unionida目)。海相三角蛤类闯入边缘隔绝的洛隆-八宿地区并演变为非海相类三角蚌类,是一次典型的边域成种事件。     

Ceramide Glycanase Activities in Human Cancer Cells

Ceramide glycanase (CGase) activities have been detected in different human tumor cells (colon, carcinoma Colo-205; neuroblastoma, IMR-32; breast cancer lines, SKBr3 and MCF7). However, the level of enzymatic activity is lower in these cells compared to that present in other mammalian tissues reported before (Basu, M., Kelly, P., Girzadas, M. A., Li, Z., and Basu, S. Methods Enzymol. (in press)). The majority of CGase activity was found in the 100,000g soluble supernatant fraction isolated from all these cell lines and tissues. Using the soluble enzyme, the requirement for optimum CGase activity was found to be consistent with previous observations found for rat and rabbit tissues (Basu, M., Dastgheib, S., Girzadas, M. A., O'Donnell, P. H., Westervelt, C. W., Li, Z., Inokuchi, J. I., and Basu, S. (1998) Acta Pol. Biochim. 42:327). The CGase activities from both Colo-205 and IMR-32 cells are optimum at a protein to detergent ratio of one. All the mammalian CGases, including human cancer cells, show an optimum pH between 5.5 and 5.8 in sodium acetate buffer. The CGase activities from cancer cells are found to be cation-independent; however, mercury, zinc, and copper ions seem to inhibit the enzyme activity substantially in both tumor cells lines. The mercury ion inhibition of CGase activities from all different sources indicates a possible structural homology in the CGase proteins.Radiolabeled substrates, labeled at the sphingosine double bond or at the 3-position of sphingosine without modifying double bond of sphingosine were used in this investigation. Both were active substrates with all enzyme preparations isolated from different cancer cells (apparent Km, 500 M for nLcOse5[³H-DT]Cer and 350 M for GgOse4[sph-3-³H]Cer with Colo-205 enzyme). Structural analogues of ceramide and sphingosine (L-PPMP, L-PDMP, alkylamines, and Tamoxifen) inhibited cancer cell CGase activities in vitro.     

Structure and genetics of the O-antigen of Escherichia coli O158

A structure of the O-polysaccharide (O-antigen) of Escherichia coli O158 has been reported (Datta, A. K.; Basu, S.; Roy, N. Carbohydr. Res.1999, 322, 219–227). In this work, we reinvestigated the O158 polysaccharide using sugar analyses, Smith degradation, and ¹H and ¹³C NMR spectroscopy and established the following structure, which is at variance with the structure established earlier:This structure is in agreement with the predicted functions of genes found in the O-antigen gene cluster of E. coli O158.
