CaNAT1, a heterologous dominant selectable marker for transformation of Candida albicans and other pathogenic Candida species

A dominant selectable marker for Candida albicans and other Candida species, which confers resistance to nourseothricin, was characterized. In a heterologous promoter system and a recyclable cassette, the marker efficiently permitted deletion and complementation of C. albicans genes. Neither growth nor filamentous development was affected in strains expressing this marker.

Gli1抑制剂GANT61对小鼠牙胚体外发育的影响

目的:研究外源性Gli1抑制剂GANT61对小鼠磨牙胚体外发育的影响。方法:采用小鼠磨牙胚体外培养系统,运用体视镜、组织学HE染色方式观察小鼠磨牙胚被Gli1抑制剂GANT61影响后的发育情况,并对牙胚构成部分进行测量。结果:在Gli1抑制剂GANT61作用下,实验组相对于对照组出现下磨牙牙胚发育速度减慢,成釉器凹陷且形态不规则,内釉上皮细胞呈现不规则排列,成釉器大小在高浓度GANT61组明显变小。结论:Gli1抑制剂GANT61可能通过扰乱成釉器的发育阻碍胎鼠磨牙胚的发育过程。     

Grey matter volume abnormalities in patients with bipolar I depressive disorder and unipolar depressive disorder:a voxelbased morphometry study

Bipolar disorder and unipolar depressive disorder(UD) may be different in brain structure. In the present study,we performed voxel-based morphometry(VBM) to quantify the grey matter volumes in 23 patients with bipolar I depressive disorder(BP1) and 23 patients with UD,and 23 age-,gender-,and educationmatched healthy controls(HCs) using magnetic resonance imaging. We found that compared with the HC and UD groups,the BP1 group showed reduced grey matter volumes in the right inferior frontal gyrus and middle cingulate gyrus,while the UD group showed reduced volume in the right inferior frontal gyrus compared to HCs. In addition,correlation analyses revealed that the grey matter volumes of these regions were negatively correlated with the Hamilton depression rating scores. Taken together,the results of our study suggest that decreased grey matter volume of the right inferior frontal gyrus is a common abnormality in BP1 and UD,and decreasedgrey matter volume in the right middle cingulate gyrus may be specifi c to BP1.     

Long-term potentiation decay and memory loss are mediated by AMPAR endocytosis

Long-term potentiation (LTP) of synaptic strength between hippocampal neurons is associated with learning and memory, and LTP dysfunction is thought to underlie memory loss. LTP can be temporally and mechanistically classified into decaying (early-phase) LTP and nondecaying (late-phase) LTP. While the nondecaying nature of LTP is thought to depend on protein synthesis and contribute to memory maintenance, little is known about the mechanisms and roles of decaying LTP. Here, we demonstrated that inhibiting endocytosis of postsynaptic α-amino-3-hydroxy-5-methyl-isoxazole-4-propionic acid receptors (AMPARs) prevents LTP decay, thereby converting it into nondecaying LTP. Conversely, restoration of AMPAR endocytosis by inhibiting protein kinase Mζ (PKMζ) converted nondecaying LTP into decaying LTP. Similarly, inhibition of AMPAR endocytosis prolonged memory retention in normal animals and reduced memory loss in a murine model of Alzheimer’s disease. These results strongly suggest that an active process that involves AMPAR endocytosis mediates the decay of LTP and that inhibition of this process can prolong the longevity of LTP as well as memory under both physiological and pathological conditions.     

中国汉族2型糖尿病人群体质量指数与血脂谱在糖尿病肾脏病中的交互作用

目的：探讨中国汉族2型糖尿病人群体质量指数（BMI）与血脂谱在糖尿病肾脏病（DKD）中的交互作用。方法：收集住院2型糖尿病患者647例,包括283例DKD患者以及364例非DKD的患者。采用二分类logistic回归分析血脂谱与DKD的相关性以及BMI与血脂谱的交互作用。结果：TG（OR=1.446,95%CI：1.076～1.942,P=0.014）、nonHDL-C（OR=1.961,95%CI：1.011～3.804,P=0.046）、nonHDL-C/HDL-C（OR=1.804,95%CI：1.134～2.869,P=0.013）、TC/HDL-C（OR=2.293,95%CI：1.234～4.260,P=0.009）、TG/HDL-C（OR=1.345,95%CI：1.057～1.712,P=0.016）均与DKD显著相关（OR针对各指标的自然对数计算）。BMI与TG、nonHDL-C/HDL-C、TC/HDL-C、TG/HDL-C之间的交互作用具有显著统计学意义（P值分别为0.036、0.035、0.034、0.016）。结论：中国汉族人群血浆TG、nonHDL-C、nonHDL-C/HDL-C、TC/HDL-C、TG/HDL-C均与DKD独立相关。BMI与TG、nonHDL-C/HDL-C、TC/HDL-C、TG/HDL-C之间存在交互作用。     

Decreased frontal lobe function in people with Internet addiction disorder

In our previous studies, we showed that frontal lobe and brainstem functions were abnormal in online game addicts. In this study, 14 students with Internet addiction disorder and 14 matched healthy controls underwent proton-magnetic resonance spectroscopy to measure cerebral function. Results demonstrated that the ratio of N-acetylaspartate to creatine decreased, but the ratio of cho- line-containing compounds to creatine increased in the bilateral frontal lobe white matter in people with Internet addiction disorder. However, these ratios were mostly unaltered in the brainstem, suggesting that frontal lobe function decreases in people with Internet addiction disorder.
