Constructing a High-Quality t-Se/Si Interface Via In Situ Light Annealing of a-Se for a Self-Powered Image Sensor.

The quality of the interface, e.g., the semiconductor-semiconductor or metal-semiconductor interface, is the main factor restricting the photodetection performance of a heterojunction.

Controlled Localized Phase Transition of Selenium for Color-Selective Photodetectors.

Color-selective photodetectors are widely applied in several fields; however, they suffer from complex fabrication and low resolution. Herein, we propose a simple and convenient design to achieve a logical color-selective heterojunction photodetector composed of CdS and Se with a crystalline/amorphous mixed state. The as-deposited amorphous Se top layer in the heterojunction is partly transformed to trigonal crystalline Se by localized in situ phase transformation during annealing.

MiR-138-5p knockdown promotes osteogenic differentiation through FOXC1 up-regulation in human bone mesenchymal stem cells.

This study examined the hypothesis that the microRNA miR-138-5p reduces the osteodifferentiation of human bone mesenchymal stem cells (hBMSCs) by downregulating the expression of forkhead box C1 (FOXC1). For this, hBMSCs were separated from bone marrow and osteogenic induction medium was added to stimulate osteogenic differentiation. Flow cytometric analysis was applied to evaluate the expression of cell-surface antigens associated with hBMSCs, including CD29, CD44, CD90, CD45, and CD34.

[Retrospective investigation of schistosomiasis endemic situation in Hunan Province].

Objective: To understand the dynamic rules of schistosomiasis endemic situation before and after reaching the criteria of schistosomiasis transmission controlled or transmission interrupted, so as to provide the evidence for improving schistosomiasis control.

Methods: Wuling District, Xihu District and Linli County were selected and investigated retrospectively to collect the schistosomiasis epidemiological information 10 years before they reached the criteria of transmission controlled and the subsequent years until 2008. A database of retrospective investigation was established for analyzing the trends and rules of changes of the Oncomelania hupensis snail status and infection status of cattle and human.

[Surveillance of endemic situation of schistosomiasis in Wuyi Village of Dongting Lake region, Hunan Province from 2002 to 2010].

Objective: To understand the epidemic trends of schistosomiasis in Wuyi Village of Muping Lake, so as to provide the references for making control strategy of schistosomiasis in embankment subtype in Dongting Lake region.

Methods: The data relating to the morbidity of schistosomiasis among human and domestic animals, the status of Oncomelania snails, the parameters of demographic and social economic development, and intervention measures were collected in Wuyi Village from 2002-2010. Based on this information, the changing trends of schistosomiasis were dynamically analyzed.

[Longitudinal investigation on intestinal parasite infections among rural people in West Dongting Lake region].

The nylon pocket concentration method and modified Kato-Katz technique were used to detect the eggs of intestinal parasites and the iodine smear method was used for the detection of protozoa among the rural population in West Dongting Lake region. The infection rate of parasites in 2006 was 11.84%, and it declined by 86.
