The transfer of Ca4' at rest and during contraction has been measured in isolated guinea-pig atria. During contraction, the rate of transfer increases considerably. The increment in the uptake of calcium by the cells of the atria during contraction is closely correlated with the strength of contraction. This relationship is maintained at different frequencies of stimulation and at different con...

Aim: The ATRIA score was developed to assess the probability of an ischemic stroke in patients with atrial fibrillation (AF). modified (M-ATRIA) risk incorporates predictive variables for coronavirus disease 2019 (COVID-19). As a result, we looked into association between M-ATRIA and in-hospital death COVID-19 patients.Materials Methods: data 595 inpatients research were evaluated retrospective...

Nitric oxide-cGMP pathway can inhibit cardiac norepinephrine (NE) release. Sympathetic hyper-responsiveness in hypertension may result from oxidative stress impairing this pathway. We tested the hypothesis that the gene transfer of neuronal NO synthase (nNOS) could restore sympathetic balance in the spontaneously hypertensive rat (SHR). An adenovirus (5x10(10) particles) constructed with a nora...

BACKGROUND Previous studies report that CHADS2 and CHA2DS2-VASc risk scores have similar discriminating ability (C statistic ∼0.6). Recently a clinically based risk score, the ATRIA (Anticoagulation and Risk Factors in Atrial Fibrillation) study risk score, was developed and validated. OBJECTIVES This study compared predictive ability of CHA2DS2-VASc and CHADS2 ischemic stroke risk scores wit...

KEY POINTS Ageing is associated with an increased risk of cardiovascular disease and arrhythmias, with the most common arrhythmia being found in the atria of the heart. Little is known about how the normal atria of the heart remodel with age and thus why dysfunction might occur. We report alterations to the atrial systolic Ca2+ transient that have implications for the function of the atrial in ...

Space syntax analysis method is used to define the regions, cities, built environments, building groups, spatial models, and indoor organizations at different scales examine their interaction with social structure. This study aimed analyse organization of traditional atria by using space reveal socio-cultural effect atria. The morphology behavioural models regarding Antakya houses Housing Devel...
