Body mass index and cancer risk among Chinese patients with type 2 diabetes mellitus.

Background: Obesity and diabetes are two risk factors for cancer. To evaluate the association of body mass index (BMI) with cancer risk in diabetic patients may improve current understanding of potential mechanisms.

Methods: A retrospective cohort study was conducted in 51,004 newly diagnosed T2DM patients derived from an electronic health record (EHR) database of Minhang district in Shanghai, China.

Strategic Design of Vacancy-Enriched FeS Nanoparticles Anchored on FeC-Encapsulated and N-Doped Carbon Nanotube Hybrids for High-Efficiency Triiodide Reduction in Dye-Sensitized Solar Cells.

A new class of hybrids with the unique electrocatalytic nanoarchitecture of FeS anchored on FeC-encapsulated and N-doped carbon nanotubes (FeS/FeC-NCNTs) is innovatively synthesized through a facile one-step carbonization-sulfurization strategy. The efficient synthetic protocols on phase structure evolution and dynamic decomposition behavior enable the production of the FeS/FeC-NCNT hybrid with advanced structural and electronic properties, in which the Fe vacancy-contained FeS showed the 3d metallic state electrons and an electroactive Fe in +2/+3 valence, and the electronic structure of the CNT was effectively modulated by the incorporated FeC and N, with the work function decreased from 4.85 to 4.

Construction of Highly Catalytic Porous TiOPC Nanocomposite Counter Electrodes for Dye-Sensitized Solar Cells.

Developing low-cost, durable, and highly catalytic counter electrode (CE) materials based on earth-abundant elements is essential for dye-sensitized solar cells (DSSCs). In this study, we report a highly active nanostructured compositional material, TiOPC, which contains titanium, oxygen, phosphorus, and carbon, for efficient CE in I/I electrolyte. The TiOPC nanocomposites are prepared from carbon thermal transformation of TiPO in an atmosphere of nitrogen at high temperature, and their catalytic performance is regulated by changing the carbon content in the nanocomposites.

Identification and evaluation of reference genes in the Chinese white wax scale insect Ericerus pela.

Background: The Chinese white wax scale insect, Ericerus pela, is a well-known resource insect. The females and males are dramatically distinct at each developmental stage. We sought to identify suitable reference genes to use as internal controls in molecular research on E.

Complete mitochondrial genome sequences of two parasitic/commensal nemerteans, Gononemertes parasita and Nemertopsis tetraclitophila (Nemertea: Hoplonemertea).

Background: Most nemerteans (phylum Nemertea) are free-living, but about 50 species are known to be firmly associated with other marine invertebrates. For example, Gononemertes parasita is associated with ascidians, and Nemertopsis tetraclitophila with barnacles. There are 12 complete or near-complete mitochondrial genome (mitogenome) sequences of nemerteans available in GenBank, but no mitogenomes of none free-living nemerteans have been determined so far.

Cloning and expression analysis of four heat shock protein genes in Ericerus pela (Homoptera: Coccidae).

To explore the function of small heat shock protein genes (shsps) and hsp70 in Ericerus pela, we cloned the full-length cDNA sequences of hsp21.5, hsp21.7, hsp70, and hsc70 and the genomic sequence of hsc70.

Transcriptome analysis of the Chinese white wax scale Ericerus pela with focus on genes involved in wax biosynthesis.

Background: The Chinese white wax scale, Ericerus pela Chavannes is economically significant for its role in wax production. This insect has been bred in China for over a thousand years. The wax secreted by the male scale insect during the second-instar larval stage has been widespread used in wax candle production, wax printing, engraving, Chinese medicine, and more recently in the chemical, pharmaceutical, food, and cosmetics industries.
