Highly Deformable High-Performance Paper-Based Perovskite Photodetector with Improved Stability.

Paper-based photodetectors have attracted extensive research interest owing to their environmentally friendly and highly deformable properties. Although perovskite crystals with outstanding optoelectronic properties have proved to be one of the most promising candidates for photodetectors, the development of paper-based photodetectors is hindered by the moisture absorptivity of paper and the instability of perovskite crystals in a humid atmosphere. In this study, we demonstrate a highly deformable and high-performance paper-based perovskite photodetector.

CD47 Overexpression Is Associated with Epstein-Barr Virus Infection and Poor Prognosis in Patients with Nasopharyngeal Carcinoma.

Purpose: Little is known about the clinical significance of CD47 expression and its association with Epstein-Barr virus (EBV) infection in patients with nasopharyngeal carcinoma (NPC). The aim of this study was to clarify the prognostic value and role of CD47 in EBV-associated NPC.

Materials And Methods: Sixty-six cases of non-metastatic NPC were retrospectively reviewed.

Phase II Study of a Bi-Weekly Chemotherapy Regimen of Combined Liposomal Paclitaxel and Nedaplatin for the Treatment of Advanced Squamous Cell Lung Cancer.

The platinum-based, two-drug, 3-week regimen is currently the main first-line chemotherapy program for the treatment of advanced squamous cell lung cancer. The aim of this phase II clinical study was to evaluate the efficacy and adverse events of the bi-weekly program of liposomal paclitaxel combined with nedaplatin as a first-line treatment for advanced squamous cell lung cancer. A total of 52 cases of advanced squamous cell lung cancer were included in this phase II clinical trial.

Various changes in cryopreserved acellular nerve allografts at -80°C.

The experimental design evaluated histological, mechanical, and biological properties of allogeneic decellularized nerves after cryopreservation in a multi-angle, multi-directional manner to provide evidence for long-term preservation. Acellular nerve allografts from human and rats were cryopreserved in a cryoprotectant (10% fetal bovine serum, 10% dimethyl sulfoxide, and 5% sucrose in RPMI1640 medium) at -80°C for 1 year, followed by thawing at 40°C or 37°C for 8 minutes. The breaking force of acellular nerve allografts was measured using a tensile test.

Analysis of EPA and DHA in the viscera of marine fish using gas chromatography.

The viscera of 10 kinds of marine fishes were collected for fish oil extraction and detection of DHA and EPA, two most important polyunsaturated fatty acids. The fish oil extraction ratio for the evaluated fishes varied from 0.95% to 10.

Molecular characterization and functional analysis of three pathogenesis-related cytochrome P450 genes from Bursaphelenchus xylophilus (Tylenchida: Aphelenchoidoidea).

Bursaphelenchus xylophilus, the causal agent of pine wilt disease, causes huge economic losses in pine forests. The high expression of cytochrome P450 genes in B. xylophilus during infection in P.

Analysis of apoptosis induced by perfluorooctane sulfonates (PFOS) in mouse Leydig cells in vitro.

To explore the possible mechanism of perfluorooctane sulfonates (PFOS's) reproductive toxicity, mouse Leydig cells cultured in vitro were exposed to a serial concentration of PFOS for four more days of culture. Apoptosis during the process was checked. After 24 h, apoptosis occurred to all of the groups ≥ 50 μg/mL PFOS.

[Correlation between aquatic plant diversity and water environment in the typical sites of Hangzhou section of the Beijing-Hangzhou Grand Canal].

Community characteristics of aquatic plant are important indicators for water quality. In order to understand the distribution characteristics of aquatic plants in aquatic ecosystem of the Beijing-Hangzhou Grand Canal ( Hangzhou section) , and to analyze the relationship between water quality and plant community, an investigation of the aquatic plants in five typical sites was made in this study. Species composition, biological diversity, quantity distribution and dominant species of aquatic plants in five sites were studied for ecological changes.

Effects of subchronic samarium exposure on the histopathological structure and apoptosis regulation in mouse testis.

To evaluate the reproductive toxicity of samarium, a widely used rare earth element, male ICR mice were orally exposed to samarium nitrate for 90 days for lesion evaluation in the testis. Decreased organ coefficients, disorganized seminiferous tubules, and decreased spermatogenic cells and sperm of the testis were observed extensively in the treated groups, indicating that the testis is a target organ of samarium. Electron microscopy confirmed that the lesions inside the spermatogenic cells and sperm mainly included mitochondrial swelling, mitochondrial vacuolization, fuzzy nuclear membranes, and marginated chromatin.
