上海奶牛 1997年第4期20卷 13-14页

作者： paul martin 储明星中国农业科学院畜牧研究所北京100094

乳牛场主的收益主要依赖于两个方面:1维持和照料奶牛的方式。2更稳定的奶牛产量、使挤奶容易或困难的形态待征、抗病力较大和生命周期更长等奶牛素质的遗传潜力。在法国,400万头乳用母牛中有300万头荷斯坦母牛。其中有2011510头母牛记... 详细信息

对防治苹果黑星病几种杀菌剂的探讨

北方果树 1991年第2期 55-56页

作者： paul martin 马亚贤

在春、夏两季气候冷凉、潮湿的国家,苹果黑星病发生危害最重。由于此病直接影响苹果的质量,果个及产量,加之喷药的花费,因而常造成严重的经济损失。有的年份,此病可使苹果减产70%以上,甚至造成苹果绝收。目前最重要的问题是减少这种病... 详细信息

在春、夏两季气候冷凉、潮湿的国家,苹果黑星病发生危害最重。由于此病直接影响苹果的质量,果个及产量,加之喷药的花费,因而常造成严重的经济损失。有的年份,此病可使苹果减产70%以上,甚至造成苹果绝收。目前最重要的问题是减少这种病菌的初次侵染源和再侵染。如果能减少初次侵染源,就会大大地减少病菌的无性繁殖。在苹果树落叶前。

This study aimed to discriminate ten Cameroonian cocoa hybrids according to their total fat, fatty acid composition, tocopherol and tocotrienol profiles. Six cocoa clones from the gene banks of the Cameroon Cocoa Development Corporation were used to create hybrids. The determination of fatty acid composition was carried out by using a gas chromatography (GC) apparatus coupled by a flame ion detector (FID). Tocopherol and tocotrienol analysis was performed by upper high-performance liquid chromatography (UHPLC). Information on the impact of the genotype on the cocoa fat composition was provided. The major fatty acids (FA) in fermented samples are stearic (34.57%), palmitic (26.13%), oleic (34.13%) and linoleic (3.16%) acids. (35.05% to 35.6%). SCA12 × ICS40, SCA12 × SNK13, SNK13 × T79/501 have the least hard cocoa butters. Tocopherols analysis showed a predominance of γ-tocopherols (94.64 ± 1.51 to 292.16 ± 3.17 µg∙g−1), whereas only a small amount of β and δ-tocopherol (from 0.46 to 2.78 µg∙g−1 and 0.12 to 5.82 respectively) was observed. No γ-tocotrienol was found in fermented samples. A differentiation in terms of total fat and tocopherol content was observed amongst hybrids with the same mother-clone, suggesting an impact of pollen on these compounds.

Background: Urinary Tract infections and pus are major public health problems. The evolution of bacterial resistance to antibiotics makes the treatment of these infections problematic. This is why this study is undertaken to identify and evaluate the resistance of Pseudomonas aeruginosa to antibiotics. Methods: This is a prospective study carried out from December 2020 to November 2021. The germs were isolated on the agar supplemented with cetrimide and identified by the API 20 NE gallery method according to the manufacturer’s protocol. The strains’ resistance profiles were determined by the diffusion method on Mueller-Hinton according to the criteria EUCAST- 2021. Results: A total of 46/1467 (3.13%) Pseudomonas aeruginosa were identified, of which 29/1008 (2.87%) were urinary tract infections and 17/459 (3.70%) were pus. The high resistances were: 97.8% to ceftazidim, 91.3% to aztreonam, 93.5% to cefepim, 82.6% to piperacillin, 58.7% to levofloxacin, 52.2% to amikacin, 47.8% to tazobactam-piperacillin, 47.8% to tobramycin and 43.5% to ciprofloxacin. Low resistance was only 2.2% to fosfomycin, 2.2% to colistin and 15.2% to imipenem. Conclusion: This study reveals the considerable resistance of Pseudomonas aeruginosa to commonly used antibiotics, and thus compromises the empirical treatment practiced in hospitals. This result motivates the need to carry out susceptibility testing of isolates before any prescription of antimicrobials.

2006年度学术研讨会

作者： Stephen J. Grimme paul S. martin Kim Tu Serguei E. Tcheperegine Katharine Corrado Anne E. Farewell Peter Orlean

The essential GAB1 gene, which encodes an endoplasmic reticulum (ER)-membrane protein, was identified in a screen for mutants defective in cellular morphogenesis. A temperature-sensitive gabl mutant accumulates complete glycosylphosphatidylinositol (GPI) precursors, and its temperature sensitivity is suppressed differentially by overexpression of different subunits of the GPI transamidase, from strong suppression by Gpi8p and Gpi17p, to weak suppression by Gaa1p, and to no suppression by Gpi16p. In addition, both Gab1p and Gpi17p localize to the ER and are in the same protein complex in vivo. These findings suggest that Gablp is a subunit of the GPI transamidase with distinct relationships to other subunits in the same complex. We also show that depletion of Gablp or Gpi8p, but not Gpi17p, Gpi16p, or Gaalp causes accumulation of cofilin-decorated actin bars that are closely associated with the perinuclear ER, which highlights a functional interaction between the ER network and the actin cytoskeleton.
