The autonomic nervous system plays a crucial role in regulating physiological processes and maintaining homeostasis through its two branches: the sympathetic nervous system (SNS) and the parasympathetic nervous system. Dysregulation of the autonomic system, characterized by increased sympathetic activity and reduced parasympathetic tone, is a common feature in chronic kidney disease (CKD) and cardiovascular disease. This imbalance contributes to a pro-inflammatory state, exacerbating disease progression and increasing the risk for cardiovascular events.

The L-type Ca channel (Ca1.2) is essential for cardiac excitation-contraction coupling. To contribute to the inward Ca flux that drives Ca-induced-Ca-release, Ca1.

Hepatorenal syndrome-acute kidney injury (HRS-AKI) occurs in the setting of advanced chronic liver disease, portal hypertension, and ascites. HRS-AKI is found in ∼20% of patients presenting to the hospital with AKI, but it may coexist with other causes of AKI and/or with preexisting chronic kidney disease, thereby making the diagnosis challenging. Novel biomarkers such as urinary neutrophil gelatinase-associated lipocalin may be useful.

Cardiologists have analyzed daily patterns in the incidence of sudden cardiac death to identify environmental, behavioral, and physiological factors that trigger fatal arrhythmias. Recent studies have indicated an overall increase in sudden cardiac arrest during daytime hours when the frequency of arrhythmogenic triggers is highest. The risk of fatal arrhythmias arises from the interaction between these triggers-such as elevated sympathetic signaling, catecholamine levels, heart rate, afterload, and platelet aggregation-and the heart's susceptibility (myocardial substrate) to them.

Background: Recent studies suggest that the anterior limb of the internal capsule may be an area of convergence for multiple compulsion loops. In this study, the role of different dopaminergic compulsion loops in the mechanism of obsessive-compulsive disorder (OCD) was investigated by selectively damaging dopaminergic neurons or fibers in the corresponding targets with 6-hydroxydopamine (6-OHDA) and depicting the anatomical map of various compulsion loops located in the anterior limb of the internal capsule.
Methods: A total of 52 male Sprague Dawley (SD) rats were exposed to either saline (1 mL/kg, NS group, n = 6) or quinpirole (QNP, dopamine D2-agonist, 0.
