Classification of Alzheimer's Disease Based on Abnormal Hippocampal Functional Connectivity and Machine Learning.

Objective: Alzheimer's disease (AD) is a neurodegenerative disease characterized by progressive deterioration of memory and cognition. Mild cognitive impairment (MCI) has been implicated as a prodromal phase of AD. Although abnormal functional connectivity (FC) has been demonstrated in AD and MCI, the clinical differentiation of AD, MCI, and normal aging remains difficult, and the distinction between MCI and normal aging is especially problematic.

No differences in brain microstructure between young KIBRA-C carriers and non-carriers.

KIBRA rs17070145 polymorphism is associated with variations in memory function and the microstructure of related brain areas. Diffusion kurtosis imaging (DKI) as an extension of diffusion tensor imaging that can provide more information about changes in microstructure, based on the idea that water diffusion in biological tissues is heterogeneous due to structural hindrance and restriction. We used DKI to explore the relationship between KIBRA gene polymorphism and brain microstructure in young adults.

[Inhibitory effects of soluble endoglin on invasive ability of cultured cytotrophoblasts of first trimester of pregnancy].

The present study aims to investigate the effects of soluble endoglin (sEng) on invasive ability of cultured cytotrophoblasts of first trimester of pregnancy. Cytotrophoblasts of normal 6 to 8-week pregnancy were cultured by trypsin digestion method, and were incubated with cell culture medium without (control group) and with 10 μg/L sEng (sEng group), respectively for 24 h. The invasive ability was determined by transwell invasion assay, and expressions of MMP-2, MMP-9 mRNA and protein were detected by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot, respectively.
