Summary: This study investigated the relationship between wall shear stress (WSS) and plaque composition in advanced atherosclerosis. The findings revealed that high time-averaged WSS (TAWSS) is associated with larger macrophage areas and necrotic core sizes, while low oscillatory shear index (OSI) is associated with larger macrophage areas. Moreover, a combination of low TAWSS and low OSI is related to larger cap thickness.

Summary: Non-alcoholic steatohepatitis (NASH) is a chronic liver disease that can progress to liver fibrosis and cancer. Patients with NASH often have a high prevalence of atherosclerosis and related cardiovascular diseases, necessitating simultaneous management of both conditions. Rodents are commonly used as animal models for NASH, but their lipoprotein profiles differ significantly from humans, making it difficult to replicate the pathology of NASH patients with atherosclerosis. Rabbits, on the other hand, have lipoprotein metabolism more similar to humans and could be a promising candidate for assessing NASH and atherosclerosis. A rabbit NASH model was developed by treating Japanese White rabbits with a newly developed high-fat high-cholesterol diet for 16 weeks, resulting in NASH and advanced fibrosis development. Atherosclerotic lesions were also observed in the aorta. This rabbit NASH model could contribute to the exploration of concurrent treatment options for human NASH and atherosclerosis.

Summary: This study investigates the changes in plaque components and local hemodynamics during the progression of atherosclerosis in rabbit aorta. Through histological and immunohistochemical staining, as well as simulations of blood flow and LDL transport, it was found that plaque thickness, plaque components, and local hemodynamics exhibit nonlinear changes during the progression of atherosclerosis.

Summary: Atherosclerosis is an inflammatory disease of large and medium-sized arteries characterized by the growth of atherosclerotic lesions. Low and oscillatory shear stress may contribute to arterial remodeling and increased pulse wave velocity. Cardiovascular magnetic resonance imaging enables evaluation of dynamic processes and assessment of hemodynamic parameters for early identification of high-risk plaques.

Summary: Despite advances in treatment, coronary artery disease (CAD) remains a major cause of illness and death worldwide. Invasive and non-invasive imaging techniques have been used to identify high-risk plaques and the vulnerable state of patients with CAD. However, the predictive value of the invasive-only approach is limited, and a more interdisciplinary approach is needed to identify both the vulnerable plaque and patient. This review summarizes and critically evaluates the modalities used for detecting high-risk plaques in patients with CAD and discusses the challenges of the vulnerable plaque concept.

Summary: Retention of circulating lipoproteins by their interaction with extracellular matrix molecules has been suggested as an underlying mechanism for atherosclerosis. The role of glypican-4 (GPC4), a heparan sulfate (HS) proteoglycan, in the development of endothelial dysfunction and plaque progression, as well as its association with inflammation in carotid plaques, was investigated. GPC4 and HS expression was found to be lower in more-inflamed plaque sections, suggesting their involvement in both early and advanced stages of atherosclerosis.

Summary: This study shows that deficiency of bilirubin is associated with increased risk of atherosclerosis and cardiovascular disease. In the experiments, mice deficient in bilirubin showed higher burden of atherosclerotic plaques, increased systemic oxidative stress, endothelial dysfunction, and hyperlipidemia. Furthermore, the study found that bilirubin deficiency selectively enhanced neutrophil-mediated inflammation and destabilization of unstable plaques.

Summary: This study examines the impact of wall shear stress on coronary atherosclerosis development, revealing that high TSVI and low WSS are associated with increased wall thickness and predict thickening in the future. The variability of WSS contraction/expansion action and WSS magnitude play a role in different hemodynamic effects on endothelial cells, helping to identify WSS features leading to coronary atherosclerosis.

Summary: Atherosclerosis and its clinical manifestations are the leading cause of death worldwide, mainly due to the rupture of vulnerable plaques and subsequent thrombosis. Traditional imaging methods are unreliable in predicting the risk of rupture, while intravascular imaging is an effective technique. This review summarizes the current literature on biomarkers for diagnosing vulnerable plaques, providing a foundation for risk stratification and treatment.

Summary: Atherosclerosis is a major cause of death globally, with myocardial infarctions often resulting from rupture or erosion of coronary plaques. Imaging modalities alone have limited ability to accurately assess plaque risk, necessitating the use of additional biomarkers. Plaque structural stress (PSS), which incorporates various variables, has been shown to be correlated with acute coronary syndrome, plaque rupture, and major adverse cardiovascular events, offering valuable prognostic information beyond imaging. This review explores the methods for calculating PSS, the imaging modalities used for modeling PSS, and the potential for refining treatment options and predicting future events based on PSS.

Summary: Proteomics analysis techniques were used to analyze the expression of spidroins in different glands of Trichonephila clavipes spiders. Only a small proportion of spidroin genes were found to be expressed as proteins, and the expression patterns varied among different glands. The combination of genomics, proteomics, microstructural, and mechanical data offers new insights for the design principles and production of high-performance bioinspired artificial fibers.

Summary: The limited regenerative capacity of the central nervous system after injury makes the reconnection and functional recovery of the affected tissue almost impossible. However, the use of biomaterials, such as functionalized silk fibroin fibers, can enhance the guidance ability of scaffolds for regenerative processes. The study shows that functionalized fibers can guide the growth of neurons, and this guidance can be further modulated through biofunctionalization with adhesion peptides. These fibers have the potential to be used as spinal cord implants to reconnect injured ends of the spinal cord.
