COVID-19 infection was mainly associated with respiratory symptoms, but lately, ischemic stroke (IS) has been reported in several cases. The incidence of IS in SARS-CoV-2 infection is increasing, and its mechanism is still not fully understood. Calcitonin gene-related peptide (CGRP) -the abundantly expressed protein in the peripheral and central nervous system- showed low expression in SARS-CoV-2 patients. This peptide is strongly implicated in regulating cerebral blood flow (CBF) and improving neurological deficits after cerebral arterial occlusion. We assume that a possible interplay between the low circulating levels of CGRP may affect CBF, thus worsening the symptoms of IS in SARS-CoV-2 patients.

Abdominoplasty is a common aesthetic procedure, and ischemic complications are rare, particularly in nonsmokers. We present 2 cases of ischemic complications in nonsmoking patients treated with fremanezumab, a biologic medication for severe migraines. A 55-year-old woman underwent lipoabdominoplasty on December 18, 2023.

Biodegradable magnesium (Mg) implant generally provides temporary fracture fixation and facilitates bone regeneration. However, the exact effects of generated Mg ions (Mg), hydrogen gas (H), and hydroxide ions (OH) by Mg degradation on enhancing fracture healing are not fully understood. Here we investigate the degradation of Mg intramedullary nail (Mg-IMN), revealing the generation of these degradation products around the fracture site during early stages.

Background: The amyloid cascade hypothesis still dominates in Alzheimer's disease (AD), and the acceleration of the clearance efficiency of amyloid-β (Aβ) has been always considered as an effective treatment option to slow the occurrence and progression of AD.
Objective: This study aims to explore the role of zkscan3 and its related pathways in AD of the microglia-mediated pathogenesis, and whether the combined effect of drugs can exert neuroprotective function.
Methods: N9 mouse microglia and HT-22 mouse hippocampal neurons were randomly divided into 6 groups, qRT-PCR technique was used to detect the gene expression level of zkscan3 and the genes related to lysosome generation and function.

Tenomodulin (TNMD) is related to chondromodulin-1, a cartilage-derived growth regulator. It is specifically expressed in hypovascular connective tissues, including tendons and ligaments. Vascular endothelial growth factor A (VEGF-A) and calcitonin gene-related peptide (CGRP) correlate with angiogenesis and neurogenesis, respectively, during development.

Migraine is a neurological disease that, while not inherently causing "chronic headaches," can evolve into a chronic condition over time including major symptoms such as nausea, and light, sound, and allodynia, particularly in cases of frequent episodic migraine or due to factors such as medication overuse or inadequate management. This condition's complex pathophysiology makes treatment difficult. Genetics, trigeminovascular system activation, and cortical spreading depression are involved.
