Transplanted organs are inevitably exposed to ischemia-reperfusion (IR) injury, which is known to cause graft dysfunction. Functional and structural changes that follow IR tissue injury are mediated by neutrophils through the production of oxygen-derived free radicals, as well as from degranulation which entails the release of proteases and other pro-inflammatory mediators. Neutrophil serine proteases (NSPs) are believed to be the principal triggers of post-ischemic reperfusion damage.

Background: Sepsis and acute respiratory distress syndrome (ARDS) are common inflammatory conditions in intensive care, with ARDS significantly increasing mortality in septic patients. PANoptosis, a newly discovered form of programmed cell death involving multiple cell death pathways, plays a critical role in inflammatory diseases. This study aims to elucidate the PANoptosis-related genes (PRGs) and their involvement in the progression of sepsis to ARDS.

Background: Neuroendocrine tumors of the thymus (NETT) are rare and malignant tumors that arise in the anterior mediastinum. These tumors can exhibit aggressive behavior and may involve surrounding critical structures, such as the superior vena cava. This case contributes to the literature by presenting a recurrent thymic carcinoma with invasion of major blood vessels, including the superior vena cava, and the complexities involved in its surgical management.

METTL3: a multifunctional regulator in diseases.

Mol Cell Biochem

January 2025

Department of Vascular Surgery, Renmin Hospital of Wuhan University, Wuhan, Hubei, China.

N6-methyladenosine (mA) methylation is the most prevalent and abundant internal modification of mRNAs and is catalyzed by the methyltransferase complex. Methyltransferase-like 3 (METTL3), the best-known mA methyltransferase, has been confirmed to function as a multifunctional regulator in the reversible epitranscriptome modulation of mA modification according to follow-up studies. Accumulating evidence in recent years has shown that METTL3 can regulate a variety of functional genes, that aberrant expression of METTL3 is usually associated with many pathological conditions, and that its expression regulatory mechanism is related mainly to its methyltransferase activity or mRNA posttranslational modification.

Aim: To investigate the association between Systematic Coronary Risk Evaluation 2 (SCORE2) and subclinical damage in two vascular beds: atherosclerosis in the coronary arteries and aortic arterial stiffness, in a large population-based cohort without cardiovascular disease or diabetes.

Methods: A cross-sectional study based on Swedish CArdio Pulmonary bioImaging Study (SCAPIS) data. A population-based cohort of 3087 participants aged 50-64.
