Single-cell RNA sequencing reveals key regulators and differentiation trajectory of iPSC-derived cardiomyocytes.

Cardiac differentiation of human pluripotent stem cells is not only a new strategy of regenerative therapy for cardiovascular disease treatment but also provides unique opportunities for the study of in vitro disease models and human heart development. To elucidate the dynamic gene regulatory networks and pivotal regulators involved in the cardiomyocyte differentiation process, we conducted an analysis of single-cell RNA sequencing data obtained from the reprogramming of two human induced pluripotent stem cell (iPSC) lines into cardiomyocytes. The data were collected from 32,365 cells at 4 stages of this process.

Online registry of neonatal necrotising enterocolitis in Shenzhen: protocol for a multicentre, prospective, open, observational cohort study.

Introduction: Necrotising enterocolitis (NEC) of the intestine of preterm infants leads to the risk of abdominal surgery, short bowel syndrome, neurodevelopmental disorders and death. Although the risks of NEC and its complications have been recognised in many countries, few countries have established NEC-specific registries to continuously monitor its aetiology and prognosis. In China, the understanding of risk factors and prognosis of NEC is incomplete, characterised by a lack of evidence from prospective and multicentre studies.

Optimizing Lactiplantibacillus plantarum viability in the gastrointestinal tract and its impact on gut microbiota-brain axis through zein microencapsulation.

Evidence suggests that Lactiplantibacillus plantarum (LP) can positively influence gut microbiota, subsequently affecting brain function via the gut-brain axis. However, the oral administration of LP may subject it to damage from gastric acid. To address this issue, a microencapsulation system was developed to protect LP and enhance its viability in the gastrointestinal tract.

Injectable polyethylene glycol/methacrylated polylysine double cross-linked hydrogel releases neuropeptides for infected wound healing.

This study was designed with the goal of synthesizing an injectable, double cross-linked hydrogel suitable for use when treating infected wounds.

Melatonin treatment increases skin microbiota-derived propionic acid to alleviate atopic dermatitis.

Background: Melatonin has been reported to relieve the inflammatory symptoms and improve sleep disturbance in patients with atopic dermatitis (AD). Recent studies showed that melatonin produced beneficial effects by remodeling intestinal microbiota composition; however, whether the beneficial effects of melatonin in AD were mediated by the modulation of skin microbiota remains unclear.

Objective: We sought to investigate the mechanism by which melatonin treatment-induced changes in the skin microbiota composition further alleviated AD.

Enhancing Epstein-Barr virus detection in IBD patients with XAI and clinical data integration.

Background: There is increasing evidence of a link between Epstein-Barr virus (EBV) and gastrointestinal cancers, particularly in immunocompromised patients and those on thiopurines. Traditional endoscopic techniques have limitations in diagnosing EBV, whereas standard methods for diagnosing EBV have practical challenges in regular clinical settings related to their invasiveness and high costs.

Methods: An explainable AI (XAI) model was developed to analyze 1598 endoscopic images from 287 patients with inflammatory bowel disease (IBD), with a focus on detecting EBV infection.

Multimodal single cell-resolved spatial proteomics reveal pancreatic tumor heterogeneity.

Despite the advances in antibody-guided cell typing and mass spectrometry-based proteomics, their integration is hindered by challenges for processing rare cells in the heterogeneous tissue context. Here, we introduce Spatial and Cell-type Proteomics (SCPro), which combines multiplexed imaging and flow cytometry with ion exchange-based protein aggregation capture technology to characterize spatial proteome heterogeneity with single-cell resolution. The SCPro is employed to explore the pancreatic tumor microenvironment and reveals the spatial alternations of over 5000 proteins by automatically dissecting up to 100 single cells guided by multi-color imaging of centimeter-scale formalin-fixed, paraffin-embedded tissue slide.

The Impact of Aging on Neurological Diseases in the Elderly: Molecular Mechanisms and Therapeutic Perspectives.

With the progression of global aging, neurological diseases in elderly individuals have aroused widespread interest among researchers. Imbalances in the homeostasis of neuronal microenvironments, including neural progenitor cells and microglia, are the leading cause of worsening neurodegenerative diseases. The aging of various glial cells can further lead to abnormal functions in the central nervous system (CNS).

A single-center clinical trial evaluating topical propranolol for preventing stress-induced hair loss.

There is currently a lack of pathological research on the hair loss caused by stress, and there is no effective treatment available. It has been previously reported that stress can cause sympathetic nerve activation and release of norepinephrine, which binds to beta-2 adrenergic receptors and causes a series of chemical reactions. Propranolol, as a beta-2 adrenergic receptors blocker, competitively antagonizes the effects of norepinephrine.

Therapeutic potential of Simvastatin in ALS: Enhanced axonal integrity and motor neuron survival through Apoa4 and Alb modulation.
