2D SiP/h-BN for a Gate-Controlled Phototransistor with Ultrahigh Sensitivity.

Two-dimensional (2D) materials are extremely attractive for the construction of highly sensitive photodetectors due to their unique electronic and optical properties. However, developing 2D photodetectors with ultrahigh sensitivity for extremely low-light-level detection is still a challenge owing to the limitation of high dark current and low detectivity. Herein, a gate-controlled phototransistor based on 2D SiP/hexagonal boron nitride (h-BN) was rationally designed and demonstrated ultrahigh sensitivity for the first time.

Strong In-Plane Anisotropic SiP as a IV-V 2D Semiconductor for Polarized Photodetection.

In-plane anisotropic two-dimensional (2D) materials, emerging as an intriguing type of 2D family, provide an ideal platform for designing and fabrication of optoelectronic devices. Exploring air-stable and strong in-plane anisotropic 2D materials is still challenging and promising for polarized photodetection. Herein, SiP, a 2D IV-V semiconductor, is successfully prepared and introduced into an in-plane anisotropic 2D family.

Genome-wide identification and expression of GRAS gene family members in cassava.

Background: Cassava is highly tolerant to stressful conditions, especially drought stress conditions; however, the mechanisms underlying this tolerance are poorly understood. The GRAS gene family is a large family of transcription factors that are involved in regulating the growth, development, and stress responses of plants. Currently, GRAS transcription factors have not been systematically studied in cassava, which is the sixth most important crop in the world.

Cinnamon extracts exert intrapancreatic cytoprotection against streptozotocin in vivo.

In the current study, we aimed to investigate the potential hypoglycemic bioactivity of cinnamon extracts (CES) on streptozotocin (STZ)-induced hyperglycemia in mice. In biological methods, glucose metabolic ability of all mice was evaluated by glucose tolerance testing (GTT). Blood levels of pancreas-produced insulin, glucagon, inflammation-associated interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) were determined via enzyme-linked immunosorbent assay (ELISA).

Diagnostic accuracy of treadmill exercise tests among Chinese women with coronary artery diseases: A systematic review and meta-analysis.

Background: The treadmill exercise test (TET) is one of the most common noninvasive diagnosis approaches for ischemic heart diseases, but potential reduction of TET accuracy among Chinese female patients was ignored by most studies, especially in perimenopause women. Hence, we aim to perform a systematic review and meta-analysis evaluating the TET diagnostic accuracy for Chinese women compared with coronary angiography (CAG).

Methods: PubMed, MEDLINE, EMBASE, CNKI and WANFANG (1990 to 2015) were performed to identify studies assessing the diagnostic accuracy of TET versus CAG.

[The immunological characteristics of tonsil mesenchymal stem cells].

Objective: To investigate the immunological characteristics of human tonsil mesenchymal stem cells (TMSCs).

Methods: Human tonsil tissues were obtained from the children patients with chronic tonsillitis. TMSCs were separated, cultured, and were detected the expression profiles of HLA-I, HLA-II, CD80, CD86 by flow cytometry.

Tupichinins B-D, three new spirostanol saponins from Tupistra chinensis rhizomes.

Three new spirostanol saponins were isolated from the EtOAc fraction of methanol extract from Tupistra chinensis rhizomes. Based on the detailed analysis of their 1D and 2D NMR spectra and chemical evidence, their structures were determined as 1β-O-acetyl-spirost-5,25(27)-dien-3α-yl-O-β-D-glucopyranoside (1), (25S)-1β,2β,5β-trihydroxy-spirostane-3β-yl-O-β-D-glucopyranoside (2) and (25S)-1β,2β-dihydroxy-5β-spirostane-3β-yl-O-β-D-xylopyranoside (3), respectively.

Osteogenic differentiated periodontal ligament stem cells maintain their immunomodulatory capacity.

Periodontal ligament stem cells (PDLSCs) have great potential for regenerating periodontal ligament tissue, which is involved in attaching teeth to the underlying alveolar bone. Recently, PDLSCs were characterized as having both low immunogenicity and profound immunomodulation abilities. Further, transplanted PDLSCs differentiate into osteoblasts in vivo.

Chemical constituents of Tupistra chinensis rhizomes.

A new pregnane glycoside, a dibenzylbutyrolactone lignan, 5-hydroxymatairesinol dimethyl ether, and three new flavonoids, including one 8-methylflavan-3-ol, and two 8-methylflavones, together with five known flavonoids and two known alkaloids were isolated from the rhizomes of Tupistra chinensis. The structures of all compounds were elucidated by spectral studies.

New flavans, spirostanol sapogenins, and a pregnane genin from Tupistra chinensis and their cytotoxicity.

Seven new compounds, including three new flavans [tupichinol A-C (1-3)], three new spirostanol sapogenins [tupichigenin D-F (4-6)], and one new pregnane genin [tupipregnenolone (7)], together with 18 known compounds, were isolated from the underground parts of Tupistra chinensis. The structures of the new compounds were elucidated by spectroscopic analysis and chemical evidence. The structures and relative stereochemistry of 1 and 9 were further confirmed by single-crystal X-ray crystallographic analysis.
