UCP2 is identified as a therapeutic target for abdominal aortic aneurysm by comprehensive bioinformatic analysis and experimental validation.

Abdominal aortic aneurysm (AAA) is a potentially life-threatening vascular condition that currently lacks effective pharmacological treatment. The disease is strongly associated with chronic inflammation, where immune cells like macrophages play a crucial role. Efferocytosis, the process by which apoptotic cells are cleared, is involved in regulating inflammation.

Plasma proteomics profiles predict the risk of future aortic aneurysm and aortic dissection.

Background: Aortic aneurysms and aortic dissections (AA/AD) are serious vascular conditions that often progress without symptoms and are associated with high mortality, highlighting the need for improved tools to predict the occurrence. This study aims to identify plasma proteins that can predict the risk of future AA/AD events, and to combine these biomarkers with traditional risk factors to construct risk prediction model.

Materials And Methods: We analyzed plasma proteomic data from 22,416 participants in the UK Biobank, measuring 2,911 proteins using the Olink Explore proximity extension assay.

Progress in research and development of biodegradable metallic vascular stents.

Vascular stents are an essential tool in cardiovascular interventional therapy, and their demand is growing with the increasing incidence of cardiovascular diseases. Compared with permanent stents, which are prone to in-stent restenosis, and drug-eluting stents, which may cause late stent thrombosis, biodegradable stents offer advantages. After providing early radial support to prevent elastic recoil, biodegradable stents gradually degrade, allowing the vessel to regain its natural physiological contractility and undergo positive remodeling.

qPCR-Based Antibiotics Resistance Assay (ACQUIRE) Reveals Widespread Macrolide Resistance in Acne Patients and Can Eliminate Macrolide Misuse in Acne Treatment.

Background: Macrolides have been widely used to treat moderate-to-severe acne for more than 50 years. However, the prevalent antibiotic resistance of Propionibacterium acnes, along with the absence of clinically available resistance tests, has made macrolide misuse a frequent occurrence around the globe, with serious consequences.

Objective: We developed (qPCR)-based antibiotics resistance assay (ACQUIRE) to enable fast and accurate detection of macrolide resistance in clinical settings, representing an opportunity to administer antibiotics more wisely and improve the quality of care.

Original Hosts, Clinical Features, Transmission Routes, and Vaccine Development for Coronavirus Disease (COVID-19).

The pandemic of coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has led to public concern worldwide. Although a variety of hypotheses about the hosts of SARS-CoV-2 have been proposed, an exact conclusion has not yet been reached. Initial clinical manifestations associated with COVID-19 are similar to those of other acute respiratory infections, leading to misdiagnoses and resulting in the outbreak at the early stage.
