Regulation of presynaptic homeostatic plasticity by glial signalling in Alzheimer's disease.

Alzheimer's disease (AD), the most common form of dementia among the elderly, affects numerous individuals worldwide. Despite advances in understanding the molecular underpinnings of AD pathology, effective treatments to prevent or cure the disease remain elusive. AD is characterized not only by pathological hallmarks such as amyloid plaques and neurofibrillary tangles but also by impairments in synaptic physiology, circuit activity and cognitive function.

Association of maternal folic acid supplementation and offspring MTRR gene polymorphism with congenital heart disease: a hospital-based case-control study in Han population.

Background: Although many studies shown that the risk of congenital heart disease (CHD) was closely related to genetic and environmental factors, the exact mechanism was still unclear. This study was to assess the association of maternal folic acid supplementation (FAS), the 5-methyltetrahydrofolate-homocysteine methyltransferase reductase (MTRR) gene polymorphisms in offspring and their interaction effects with the risk of CHD and its subtypes.

Methods: A case-control study was conducted on 595 children with CHD and 605 healthy child controls.

Electrochemical Quantification of miRNA Based on Strain-Promoted Azide-Alkyne Cycloaddition Ligated Tetrahedral DNA Nanotags.

Highly sensitive and accurate detection of disease biomarkers is of great importance for diagnosis, staging, and treatment of certain diseases. Herein, we report a novel electrochemical method for the quantification of miRNA biomarkers with DNA tetrahedrons as the signal reporters. Upon the initiation of DNA hairpin opening by miRNA at the electrode interface, the hidden click reaction group is exposed for the bioconjugation with a tetrahedral DNA nanostructure, which carries multiple electrochemical species.

Objective: To assess the efficacy and safety of linear accelerator-based fractionated stereotactic radiotherapy (LINAC-FSRT) in patients with brain metastases (BM).

Methods: We retrospectively analyzed 214 patients treated with LINAC-FSRT, categorized based on biologically effective dose (BED10, / = 10) into two groups (≤55 Gy, >55 Gy). Stratified analyses were conducted based on targeted therapy to compare survival outcomes.

From Chains to Arrays: Substrate-Mediated Self-Assembly of Diboron Molecules.

In this study, we explore the substrate-mediated control of self-assembly behavior in diboron molecules (CHBO, BCat) using scanning tunneling microscopy (STM). The structural transformation of BCat molecules from one-dimensional (1D) molecular chains to two-dimensional (2D) molecular arrays was achieved by changing the substrate from Au(111) to bilayer graphene (BLG), highlighting the key role of substrate interactions in determining the assembly structure. Notably, the B-B bond in the molecular arrays on BLG is distinctly pronounced, reflecting a more refined molecular resolution with distinct electronic states than that on Au(111).

Withering and Fermentation Affect the Transformation and Accumulation of Key Metabolites in Rougui () for the Formation of Special Taste Characteristics.

During the production of Wuyi rock tea, withering and fermentation play a crucial role in the primary processing of the tea, greatly influencing the development of its distinct taste characteristics. In this study, Rougui () was selected as the research object to investigate the effects of withering and fermentation on metabolites and taste characteristics in tea leaves. The findings revealed that a total of 1249 metabolites were detected in Rougui leaves at various processing stages, of which only 40 key metabolites were significantly altered.

Longitudinal association between ADL disability and depression in middle-aged and elderly: national cohort study.

Background: The decline in daily living abilities (ADL) among older adults is a notable predictor of depressive symptoms and the occurrence of disease. However, the effects of changes in ADL disability on the progression of depression have not been extensively studied.

Objective: This research aims to examine the relationship between current ADL disability and depression in individuals aged 45 and older, as well as to explore how ADL disability influences the progression of depression in later life within China.

CsCPC, an R3-MYB transcription factor, acts as a negative regulator of citric acid accumulation in Citrus.

The citric acid accumulation during fruit ripening determines the quality of fleshy fruits. However, the molecular mechanism underlying citric acid accumulation is not clearly understood yet in citrus due to the scarcity of paired germplasm that exhibits significant difference in organic acid accumulation. Two citrus triploid hybrids with distinct citric acid content in their mature fruits were herein identified from a previously conducted interploidy cross in our group, providing an ideal paired material for studying acid accumulation in citrus.

Evaluation of cryptococcal antigen testing using a novel chemiluminescence assay in two medical centers of China.

Examining how topicality impacts pronoun resolution in second language processing.

In research on second language (L2) processing, the processing of reference has been highlighted as a domain of particular difficulty, but the source of the difficulty is not well understood. The present study examines whether differences in the pronominal systems of the first language (L1) and L2 impact processing. We take a novel approach, testing a group of intermediate-advanced L2 learners in both their L1 (Mandarin Chinese) and L2 (English), allowing us to directly examine whether L2 learners show similar or different patterns when processing the L1 and L2.
