2006年发现了一个可引起生殖道感染的沙眼衣原体(Chlamydia trachomatis,CT)新变种(New variant of CT,nvCT)。该菌株是菌株质粒中缺失了377个碱基对(base pair,bp)长片段,该缺失的片段是当时的罗氏和雅培诊断试剂目标片段区域。... 2006年发现了一个可引起生殖道感染的沙眼衣原体(Chlamydia trachomatis,CT)新变种(New variant of CT,nvCT)。该菌株是菌株质粒中缺失了377个碱基对(base pair,bp)长片段,该缺失的片段是当时的罗氏和雅培诊断试剂目标片段区域。该缺失导致了许多假阴性诊断的nvCT能够在人群中迅速传播。尽管许多核酸诊断试剂公司已经研发了新的能够检测nvCT的试剂,但目前我国国内nvCT的主要经性传播,有研究显示年轻女性更易感染。因此,探讨暗娼对其生殖道感染nvCT的可能情况,为进一步制定控制CT感染及其检测诊断方法提供依据。 展开更多

The aim of the work is the comparison of the epidemiology of influenza and acute respiratory virus infections (ARVI) in the Republic of Kazakhstan with the corresponding influenza epidemic in Russia induced by influenza pandemic virus A/California/07/2009 in 2009.Data on influenza and ARVI from the Republic of Kazakhstan and Federal Center of influenza was collected and investigated over the course of several weeks from hospitalized patients with the same diagnosis among all population and in age groups on 16 territories of Kazakhstan and in 49 major cities of Russia.The epidemic in Kazakhstan resembled the Russian epidemic in terms of its abnormally early beginning,expression of monoaetiology,the spread of the epidemic into all territories and start of the epidemics among adult population.High percentage of hospitalized people and lethal outcome were registered in this epidemic.Similarity of epidemic process character in corresponding border-line territories of both countries was found out. 展开更多

Temperature thresholds during the rice (Oryza sativa L.) cycle development have been reported to affect plant metabolism Therefore, this study aimed to evaluate the effects of the above-optimal temperature on photosynthetic and morphometric parameters in two contrasting irrigated rice genotypes (BRS Quer^ncia--sensitive and Nagina 22 (N22)~tolerant). Plants of both genotypes were grown in rhizotrons and always maintained under two temperature conditions: Out--under environmental temperature conditions, and In--rhizotrons inside a plastic structure, which increased the temperature about 3 ~C to 5 ~C above the external one. In the genotype N22, there was an increase (twofold higher) in CO2 assimilation in plants cultivated under elevated temperature (In). In BRS Quer^ncia, the stomatal conductance (gs) and transpiration rate (E) decreased upon high temperature. The rise in the temperature also negatively impacted in the modulated fluorescence parameters in both genotypes. Increases in root dry weight (RDW) and shoot dry weight (SDW) were also observed in the genotype N22 when compared to BRS Quer^ncia upon temperature rise. In general, the N22 genotype showed greater response to the above-optimal temperature due to its intrinsic thermotolerance traits over BRS Quer^ncia. Thus, N22 appeared as a potential donor of heat tolerance genes aiming to obtain new cultivar to face current global wanning. 展开更多
