Blood vessels are often subjected to axial torsion (or twist) due to body movement or surgery. However, there are few studies on blood vessel under twist. This review first summarizes the clinical observation on the twist of blood vessels and then presents what we know about the mechanical behaviors of blood vessel under twist, including the constitutive models. The state of art researches on the remodeling of blood vessels under twist via organ culture, animal experiments, and mathematical model simulations are further discussed. It is our hope that this review will draw attention for further in-depth studies on the behavior and remodeling of blood vessels under twist.

In Plasmodium falciparum malaria, infected cells accumulate in blood vessels of organs, including the brain. Recently, Reyes et al. identified monoclonal antibodies that stop infected cells from binding to the endothelial protein C receptor (EPCR) in a model of brain blood vessels.

Background: The complex structure and function of the cerebrum make it a key focus in neuroscience research. It develops from telencephalic vesicles through processes such as cell growth, division, and migration from the neuroepithelium's ventricular matrix, forming the six-layered isocortex or neocortex. Multipotent neuroepithelial cells give rise to both neuronal and glial precursors, which populate the cerebral cortex.

Background: Accumulation of β-amyloid (Aβ) in the brain is a hallmark of Alzheimer's Disease (AD). Cerebral deposition of Aβ initiates deteriorating pathways which eventually can lead to AD. However, the exact mechanisms are not known.

Introduction: Metabolic syndrome (MetS) is a metabolic disorder related to obesity and insulin resistance and is the primary determinant of the development of low-intensity chronic inflammation. This continuous inflammatory response culminates in neuroimmune-endocrine dysregulation responsible for the metabolic abnormalities and morbidities observed in individuals with MetS. Events such as the accumulation of visceral adipose tissue, increased plasma concentrations of free fatty acids, tissue hypoxia, and sympathetic hyperactivity in individuals with MetS may contribute to the activation of the innate immune response, which compromises cerebral microcirculation and the neurovascular unit, leading to the onset or progression of neurodegenerative diseases.

Objective: This study aimed to investigate and compare the histological response of rabbit dental pulp after direct pulp capping with 3 different materials: mineral trioxide aggregate (MTA), nanoparticles of fluorapatite (Nano-FA), and nanoparticles of hydroxyapatite (Nano-HA) after 4 and 6-week time intervals.

Material And Methods: A total of 72 upper and lower incisor teeth from 18 rabbits were randomly categorized into 3 groups)24 incisors from six rabbits each. MTA Group: teeth were capped with MTA.
