A tranexamic acid-functionalized acellular dermal matrix sponge co-loaded with magnesium ions: Enhancing hemostasis, vascular regeneration, and re-epithelialization for comprehensive diabetic wound healing.

Excessive inflammation, accumulation of wound exudate, and blood seepage are common in diabetic wounds, hindering cell proliferation and disrupting tissue remodeling, leading to delayed healing. This study presents a multifunctional sponge scaffold (PT@Mg) created by combining an acellular dermal matrix with tranexamic acid and MgO nanoparticles, designed for hemostatic and anti-inflammatory effects. The PT@Mg scaffold effectively absorbs wound fluid while promoting healing.

Cardiometabolic index and the risk of new-onset chronic diseases: results of a national prospective longitudinal study.

Therefore, we aim to explore the association of cardiometabolic index (CMI) and new-onset chronic diseases.

Methods: The analysis utilized data from the China Health and Retirement Longitudinal Study, with a baseline in 2011 and follow-ups biennially until 2020.

Unexpected Findings of Duchenne Muscular Dystrophy in Prenatal Screening of Chromosome Abnormality Based on Cell-Free Fetal DNA.

Objective:  This study aims to assess the feasibility of detecting and diagnosing Duchenne muscular dystrophy (DMD) during prenatal screening for chromosome abnormalities using cell-free fetal DNA extracted from peripheral blood samples of pregnant women.

Study Design:  Two pregnant women identified as high risk through noninvasive prenatal testing (NIPT) underwent amniocentesis to obtain fetal cells. Subsequent fetal chromosomal karyotyping was conducted, and genomic DNA from fetal cells was extracted for copy number variation sequencing (CNV-Seq) analysis, complemented by multiplex ligation-dependent probe amplification (MLPA) to detect deletions or duplications within the DMD gene.

Prospective cohort study of 5-aminolevulinic acid photodynamic therapy for cervical low-grade squamous intraepithelial lesions with human papillomavirus infection.

Background: Some patients with cervical low-grade squamous intraepithelial lesions (LSIL) undergo invasive laser ablation or loop electrosurgical excision procedures. Photodynamic therapy (PDT) is a photosensitizer 5-aminolevulinic acid (5-ALA)-based minimally invasive technique that causes minimal normal tissue and cell damage. We investigated 5-ALA-mediated PDT efficacy for cervical LSIL complicated by human papillomavirus (HPV).

Periconceptional Folic Acid Supplementation and Risks of Small and Large for Gestational Age at Birth: The Mediation Effects of Maternal Homocysteine Level during Pregnancy.

Background: Periconceptional folic acid supplementation (FAS) is widely recommended. However, the role of periconceptional FAS on neonatal birth weight remains unclear.

Objectives: This study aimed to explore the independent effects of periconceptional FAS on risks of small for gestational age (SGA) and large for gestational age (LGA) and to test the potential mediation role of maternal homocysteine (Hcy) during pregnancy on the above significant associations.

Associations between antimony exposure and glycated hemoglobin levels in adolescents aged 12-19 years: results from the NHANES 2013-2016.

Objective: This study aimed to investigate the association between antimony (Sb) exposure and glycated hemoglobin (HbA1c) levels in adolescents.

Methods: A cross-sectional study of 751 adolescents aged 12-19 years was conducted via the National Health and Nutrition Examination Survey (NHANES, 2013-2016). Survey-weighted linear regression and restricted cubic spline (RCS) analyses were applied to evaluate the relationship of urinary Sb exposure with HbA1c.

Allergenic protein-induced type I hypersensitivity models: a review.

Context: Type I hypersensitivity affects approximately one-third of the global population. As the pathophysiology underlying the development of type I hypersensitivity (asthma, food allergy, and anaphylactic shock, etc.) is complex and heterogeneous, animal model studies continue to be the key to identifying novel molecular pathways and providing therapeutic strategies.

NAT10-mediated RNA ac4C acetylation contributes to the myocardial infarction-induced cardiac fibrosis.

Cardiac fibrosis is featured cardiac fibroblast activation and extracellular matrix accumulation. Ac4C acetylation is an important epigenetic regulation of RNAs that has been recently discovered, and it is solely carried out by NAT10, the exclusive enzyme used for the modification. However, the potential regulatory mechanisms of ac4C acetylation in myocardial fibrosis following myocardial infarction remain poorly understood.
