The visual system is essential for human perception, converting light signals into electrical impulses and transmitting them to the brain to process environmental information. As individuals age, their physiological functions gradually decline, leading to age-related vision impairment that significantly impacts the quality of life in elderly individuals. China is home to the world's largest aging population and faces significant challenges in combating visual system aging through effective treatments and interventions.

Here we conducted single-cell transcriptomic analysis of human lung tissues including 19 post-tuberculosis lung tissues and 13 matched normal lung samples as controls, focusing on areas within and surrounding tuberculosis lesions. We identified tuberculosis-associated molecular signatures across various cell types, including gene expression patterns associated with senescence, inflammation, fibrosis and apoptosis.

Background: Immune rejection remains a leading cause of graft loss following organ transplantation, with CD4 T cells playing a central role in this process. The PI3K/AKT/mTOR signaling pathway is essential for the activation, proliferation, and metabolic reprogramming of CD4 T cells, making it an attractive therapeutic target. However, the role of Idelalisib (ID), a selective PI3Kδ inhibitor, in transplant immunity remains underexplored.

Our comprehensive analysis combining single-cell and histopathological profiling in aging Macaca fascicularis demonstrates progressive cochlear degeneration featuring accelerated sensory hair cell loss, senescent spiral ganglion neurons with elevated neuroinflammation, and marked stria vascularis atrophy. We discovered that downregulation of transmembrane transport proteins, particularly SLC35F1, serves as a critical biomarker of hair cell aging.

Here, a thermostable patulin-degrading lipase, Est from , is identified and characterized. It retains over 50% residual activity after heat treatment at 85 °C for 120 min, and its thermostability is the highest of known patulin-degrading enzymes.

We synthesized hybrid membranes by incorporating polyionic liquids (IL) and covalent organic frameworks (COF) into N-sulfopropyl CS (NCS). The addition of these components enhanced the membranes mechanical and thermal stability through strong hydrogen bonding and acid-base interactions.

To improve anticancer outcomes, various types of cisplatin-based nanomedicines have been developed, either through direct incorporation or coordination of cisplatin within nanoparticles (NPs). During the formulation and characterization of cisplatin-loaded NPs, quantitative determination of cisplatin is crucial for both clinically used and newly developed NPs.

Elucidating the regulatory mechanisms of human cardiac aging remains a great challenge. Here, using human heart tissues from 74 individuals ranging from young (≤35 years) to old (≥65 years), we provide an overview of the histological, cellular and molecular alterations underpinning the aging of human hearts. We decoded aging-related gene expression changes at single-cell resolution and identified increased inflammation as the key event, driven by upregulation of ARID5A, an RNA-binding protein.

The objective of this study is to further explore the potential causal relationship between gut microbiota and IVDD using a bidirectional Mendelian randomization approach, with the aim of identifying potential microbial characteristics associated with IVDD.
Methods: Using the data from genome-wide association studies (GWAS) involving 412 gut microbiota species and 227,388 controls and 29,508 cases of IVDD.
Hearing is one of the most vital sensory functions in human beings and a crucial means of perceiving and acquiring information from the natural environment. The advancement of human society is closely linked to the development of language, with hearing serving as the foundation for verbal communication. As individuals age, the deterioration of the auditory system becomes a significant factor contributing to sensory impairments in the elderly.

Most patients suffer from a risk of difficult-to-cure as well as severe systemic toxicity when receiving standard chemotherapies. As hyaluronic acid (HA) is a specific ligand of CD44 highly expressed by LSCs, we had HA self-assembled with cisplatin and daunorubicin to form a dual chemodrug nanogel (HA/Cis/Dau) to afford the targeted therapeutic interventions of rrAML.
