Depressive symptoms and chronic disease trajectories and predictors in middle-aged and older adults in China: An eight-year multi-trajectory analysis.

This study aims to identify and predict latent trajectories of depression and chronic disease among middle-aged and older adults in China using data-driven and interpretable machine learning methods, and to explore key factors that promote healthy aging. To achieve this, we analyzed longitudinal data from 13,073 middle-aged and older adults in the China Health and Retirement Longitudinal Study (CHARLS). Group-based multi-trajectory modeling (GBMTM) was applied to identify latent trajectory groups for depression and chronic disease statuses.

E3 ligase substrate adaptor SPOP fine-tunes the UPR of pancreatic β cells.

The Cullin-3 E3 ligase adaptor protein SPOP targets proteins for ubiquitination and proteasomal degradation. We previously established the β-cell transcription factor (TF) and human diabetes gene PDX1 as an SPOP substrate, suggesting a functional role for SPOP in the β cell. Here, we generated a β-cell-specific deletion mouse strain ( ) and found that is necessary to prevent aberrant basal insulin secretion and for maintaining glucose-stimulated insulin secretion through impacts on glycolysis and glucose-stimulated calcium flux.

The Enhancement of the Thermal Conductivity of Epoxy Resin Reinforced by Bromo-Oxybismuth.

With the gradual miniaturization of electronic devices, the thermal conductivity of electronic components is increasingly required. Epoxy (EP) resins are easy to process, exhibit excellent electrical insulation properties, and are light in weight and low in cost, making them the preferred material for thermal management applications. In order to endow EPs with better dielectric and thermal conductivity properties, bromo-oxygen-bismuth (BiOBr) prepared using the hydrothermal method was used as a filler to obtain BiOBr/EP composites, and the effect of BiOBr addition on the properties of the BiOBr/EP composites was also studied.

A PDX1 cistrome and single-cell transcriptome resource of the developing pancreas.

Pancreatic and duodenal homeobox 1 (PDX1) is crucial for pancreas organogenesis, yet the dynamic changes in PDX1 binding in human or mouse developing pancreas have not been examined. To address this knowledge gap, we performed PDX1 ChIP-seq and single-cell RNA-seq using fetal human pancreata. We integrated our datasets with published datasets and revealed the dynamics of PDX1 binding and potential cell lineage-specific PDX1-bound genes in the pancreas from fetal to adult stages.

Formation mechanism of zigzag patterned P(NIPAM--AA)/CuS composite microspheres by biomimetic mineralization for morphology modulation.

Poly(-isopropylacrylamide--acrylic acid)/copper sulfide (P(NIPAM--AA)/CuS) composite microspheres with variable zigzag patterned surfaces have been synthesized by employing an biomimetic mineralization reaction between HS and Cu immersed in P(NIPAM--AA) microspheres for morphology modulation. The morphology and composition of the P(NIPAM--AA)/CuS composite microspheres with zigzag patterned surfaces prepared in different conditions were characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectrometry (FT-IR). The polymeric microgels swelled by Cu(Ac) solution after freeze-drying treatment were of porous structure, indicating that there were polymeric frameworks and rich-water domains in the microgels before the deposition.

Facile synthesis of superhydrophobic MS/TiO/PDMS sponge for efficient oil-water separation.

To obtain a kind of superhydrophobic sponge with high oil and water selectivity, the MS/TiO/PDMS sponge was prepared via a two-step hydrophobic fabrication based on the melamine sponge (MS), tetrabutyl titanate (TBOT), and polydimethylsiloxane (PDMS). The effects of modification time, the concentrations of TBOT and PDMS on the properties of the MS/TiO/PDMS sponge were studied, and the separation mechanism was also discussed based on the interaction between the oil and the surface of the MS/TiO/PDMS sponge. The results suggest that under optimal conditions, the MS/TiO/PDMS sponge show superhydrophobicity.

JUND regulates pancreatic β cell survival during metabolic stress.

Objective: In type 2 diabetes (T2D), oxidative stress contributes to the dysfunction and loss of pancreatic β cells. A highly conserved feature of the cellular response to stress is the regulation of mRNA translation; however, the genes regulated at the level of translation are often overlooked due to the convenience of RNA sequencing technologies. Our goal is to investigate translational regulation in β cells as a means to uncover novel factors and pathways pertinent to cellular adaptation and survival during T2D-associated conditions.

Solvation effect and binding of rhaponticin with iron: a spectroscopic and DFT/TDDFT study.

In this article, both experimental and computational methods are employed to investigate the photophysics of rhaponticin (RH). The bathochromic shift was observed in absorption and fluorescence spectra with increasing solvent polarity, which implied that the charge transition of RH involved was π → π*. The results showed that RH possess strong intramolecular charge transfer (ICT), and the most important parameter to characterize the photophysical behavior of RH is the intermolecular hydrogen bonding ability of the solvent.

A PDX1-ATF transcriptional complex governs β cell survival during stress.

Objective: Loss of insulin secretion due to failure or death of the insulin secreting β cells is the central cause of diabetes. The cellular response to stress (endoplasmic reticulum (ER), oxidative, inflammatory) is essential to sustain normal β cell function and survival. Pancreatic and duodenal homeobox 1 (PDX1), Activating transcription factor 4 (ATF4), and Activating transcription factor 5 (ATF5) are transcription factors implicated in β cell survival and susceptibility to stress.
