Background: Cardiovascular disease causes vascular dementia and contributes to most clinical dementia. This is embodied in the concept of vascular contributions to cognitive impairment and dementia (VCID). The potent endogenous peptide endothelin-1 (ET1) causes small artery vasoconstriction and fibrosis.

It remains unclear why unilateral proximal carotid artery occlusion (UCAO) causes benign oligemia in mice, yet leads to various outcomes (asymptomatic-to-death) in humans. We hypothesized that inhibition of nitric oxide synthase (NOS) both transforms UCAO-mediated oligemia into full infarction and expands pre-existing infarction. Using 900 mice, we i) investigated stroke-related effects of UCAO with/without intraperitoneal administration of the NOS inhibitor (NOSi) N-nitro-L-arginine methyl ester (L-NAME, 400 mg/kg); ii) examined the rescue effect of the NO-donor, molsidomine (200 mg/kg at 30 minutes); and iii) tested the impact of antiplatelet medications.

Physiological and hematological traits and productive performance of Spanish Majorera and Palmera goats reared on the Island of Tenerife-Spain were assessed. 50 adult, clinically healthy, multiparous female goats were studied for 18 months. The data were analyzed in a two (breeds) x four (season) factorial scheme.

Vascular smooth muscle cells (VSMCs) and endothelial cells (ECs) act together to regulate blood pressure and systemic blood flow by appropriately adjusting blood vessel diameter in response to biochemical or biomechanical stimuli. Ion channels that are expressed in these cells regulate membrane potential and cytosolic Ca concentration ([Ca]) in response to such stimuli. The subsets of these ion channels involved in Ca signaling often form molecular complexes with intracellular molecules via scaffolding proteins.

Methylergometrine has widely been used pharmacologically to treat conditions such as pain, addiction, vasoconstriction, migraines, and Parkinson's disease. Despite its side effects, it is used as a therapeutic agent and research material for various diseases based on its natural potential; however, the regulatory effect of its interaction with the nicotinic acetylcholine receptor (nAChR) has not yet been investigated. The α3β4 nAChR is an ion channel essential for neurotransmission within the sympathetic, parasympathetic, and autonomic nervous systems.
