Metal borates are excellent source materials for exploring short-wavelength nonlinear optical (NLO) crystals. Galloborates show rich structural chemistry with various coordination configurations of Ga cation and B-O anionic units and are suitable candidates as ultraviolet NLO crystals. Up to now, the shortest cut-off edge of galloborates was reported to be down to 190 nm in KCsGa(BO)(OH), while the largest second harmonic generation (SHG) effect of galloborates was reported to be up to 4.

Objective: Although prolactin (PRL) is known to affect food intake, weight gain, and insulin resistance, its effects on lipid metabolism and underlying mechanisms remain underinvestigated. This study aimed to investigate the effects of PRL and its receptor (PRLR) on fat metabolism in regulating the JAK2/STAT5 signaling pathway.
Methods: SW872 adipocytes were incubated with oleic acid to establish an insulin resistance (IR) model.
Background: Lupeol exhibits novel physiological and pharmacological activities, such as anticancer and immunity-enhancing activities. However, cytotoxicity remains a challenge for triterpenoid overproduction in microbial cell factories. As lipophilic and relatively small molecular compounds, triterpenes are generally secreted into the extracellular space.

Yarrowia lipolytica, as an oleaginous yeast, is a promising microbial cell factory for the production of highly hydrophobic compounds due to the ability of this organism to accumulate large amounts of lipids that can store hydrophobic products and supply sufficient precursors for terpene synthesis. However, engineering for the heterologous production of betulinic acid and related triterpenoids has not developed as systematically as that for the production of other terpenoids, thus the production of betulinic acid in microbes remains unsatisfactory.

As an increasing number of mono-ADP-ribosyltransferases have been identified in recent studies, the functions of mono-ADP-ribosylated proteins have aroused research interest. In particular, histones are substrates of some mono-ADP-ribosyltransferases and mono-ADP-ribosylated histone have been detected in physiological or pathological processes.

We previously reported that the expression of ART1 in human colon adenocarcinoma tissues was higher than in adjacent tissues. Herein, we primarily revealed that ART1 could regulate the epithelial-mesenchymal transition (EMT) and, therefore, the development of colon carcinoma.

Methods: From July 2010 to December 2012, 72 infertile patients with PCOS undergoing assisted reproductive technology treatment in the Affiliated First Hospital of Wenzhou Medical University were enrolled in this study. The patients were divided into 2 groups, which were patients with early follicular phase down-regulation IVM (36 cases) at IVM group and early follicular phase down-regulation long protocol IVF (36 cases) at IVF group.
