p16 promoted progress of MCT induced pulmonary hypertension via maintaining redox balance and autophagy pathway.

Pulmonary arterial hypertension (PAH) is a disease characterized by increased pulmonary vascular resistance and elevated pulmonary arterial pressure. Currently, pathogenesis of PAH remains poorly understood, and therapeutic options are limited. In this study, we aimed to explore role of p16INK4A (p16) in the development of PAH using mouse model induced by monocrotaline (MCT).

Apaf-1 is an evolutionarily conserved DNA sensor that switches the cell fate between apoptosis and inflammation.

Apoptotic protease activating factor 1 (Apaf-1) was traditionally defined as a scaffold protein in mammalian cells for assembling a caspase activation platform known as the 'apoptosome' after its binding to cytochrome c. Although Apaf-1 structurally resembles animal NOD-like receptor (NLR) and plant resistance (R) proteins, whether it is directly involved in innate immunity is still largely unknown. Here, we found that Apaf-1-like molecules from lancelets, fruit flies, mice, and humans have conserved DNA sensing functionality.

Osteochondral lesions of the talus with small cysts may not affect the outcome of arthroscopic microfracture: A systematic review and meta-analysis.

Background: The optimal treatment of Osteochondral lesion of the talus (OLT) for subchondral bone cysts (SBCs) has not been finalized. The purpose of this systematic review and meta-analysis was to define whether OLT with small SBCs will affect the clinical outcomes of OLTs after arthroscopic microfracture.

Methods: We searched the Embase, Cochrane Library and PubMed databases up to May 13, 2024 for eligible comparative studies.

Early psilocybin intervention alleviates behavioral despair and cognitive impairment in stressed Wistar rats.

Chronic stress exerts profound effects on mental health, contributing to disorders such as depression, anxiety, and cognitive impairment. This study examines the potential of psilocybin to alleviate behavioral despair and cognitive deficits in a rodent model of chronic stress, focusing on the interplay between the Hypothalamic-Pituitary-Adrenal (HPA) axis and the Endocannabinoid System (ECS). Twenty-two male Wistar rats were divided into control and stress groups.

Photocatalytic Dehalogenation of Aryl Halides Mediated by the Flexible Metal-Organic Framework MIL-53(Cr).

The catalytic potential of flexible metal-organic frameworks (MOFs) remains underexplored, particularly in liquid-phase reactions. This study employs MIL-53(Cr), a prototypical "breathing" MOF capable of structural adaptation via pore size modulation, as a photocatalyst for the dehalogenation of aryl halides. Powder X-ray diffraction and Pair Distribution Function analyses reveal that organic solvents influence pore opening, while substrates and products dynamically adjust the framework configuration during catalysis.
