P2YR-IGFBP2 signaling: new contributor to astrocyte-neuron communication.

In a recent article published in Nature Communications (Shigetomi et al Nat Commun 15(1):6525, 2024), Shigetomi et al. identified that upregulated astrocytic purinergic P2Y receptors (P2YR), acting via the downstream molecule, insulin-like growth factor binding protein 2 (IGFBP2), play a crucial role in neuronal hyperexcitability. In epilepsy and stroke models, P2YR-IGFBP2 signaling was found to mediate astrocyte-driven neuronal hyperexcitability and so is a new contributor to astrocyte-neuron communication.

Development and validation of a risk prediction model for gestational diabetes mellitus in women of advanced maternal age during the first trimester.

With the global rise in advanced maternal age (AMA) pregnancies, the risk of gestational diabetes mellitus (GDM) increases. However, few GDM prediction models are tailored for AMA women. This study aims to develop a practical risk prediction model for GDM in AMA women.

Lysine succinylome analysis of MRSA reveals critical roles in energy metabolism and virulence.

MRSA's resistance poses a global health challenge. This study investigates lysine succinylation in MRSA using proteomics and bioinformatics approaches to uncover metabolic and virulence mechanisms, with the goal of identifying novel therapeutic targets. Mass spectrometry and bioinformatics analyses mapped the MRSA succinylome, identifying 8 048 succinylation sites on 1 210 proteins.

Cross-sectional and longitudinal associations between serum vitamin D and continuous metabolic syndrome score among children and adolescents: roles of levels of inflammation in peripheral blood.

Background: Serum vitamin D deficiency is intricately linked to metabolic disorders, however, evidence on its association with continuous metabolic risk in children and adolescents remains insufficient. This study aims to elucidate the relationship between serum vitamin D levels and continuous metabolic risk.

Methods: The cross-sectional analysis involved 4490 participants aged 6 ~ 18, and the longitudinal investigation included 1398 individuals aged 6 ~ 12 years.

Exogenous diethyl aminoethyl hexanoate alleviates the damage caused by low-temperature stress in Phaseolus vulgaris L. seedlings through photosynthetic and antioxidant systems.

Background: Phaseolus vulgaris is a warm-season crop sensitive to low temperatures, which can adversely affect its growth, yield, and market value. Exogenous growth regulators, such as diethyl aminoethyl hexanoate (DA-6), have shown potential in alleviating stress caused by adverse environmental conditions. However, the effects that DA-6 has on P.
