In rodents, repeated exposure to unavoidable aggression followed by sustained sensory treat can lead to prolonged social aversion. The chronic social defeat stress model explores that phenomenon and it has been used as an animal model for human depression. However, some authors have questioned whether confounding effects may arise as the model also boosts anxiety-related behaviors. Despite its ...

The aim of this work was to investigate if eletroacupuncture at PC6 would modulate the stress-induced anxiety-like behavior and the level of activation of several brain areas. Rats were distributed in groups: control; submitted to immobilization; submitted to immobilization and eletroacupuncture at PC6 or at the tail. Immobilization increased grooming and decreased stretched attend postures and...

Objective: To evaluate heart rate (HR), systolic arterial pressure (SAP), diastolic arterial pressure (DAP), mean arterial pressure (MAP) and double product (DP) responses in the seated posture of the Global Postural Reeducation (GPR) method. Methods: Nine healthy female volunteers (23±2.1 years; 56.4±7.8kg; 1.61±0.05m, 21.6±2.4kg/m2), without experience of the GPR, method underwent a treatment...

The upright posture strengthens the coupling between heart period (HP) and systolic arterial pressure (SAP) consistently with a greater contribution of the arterial baroreflex to cardiac control, while paradoxically decreasing cardiac baroreflex sensitivity (cBRS). To investigate the physiological mechanisms that mediate the coupling between HP and SAP in response to different postures, we anal...

BACKGROUND Serum amyloid P component (SAP) is a glycoprotein that is universally found associated with different types of amyloid deposits. It has been suggested that it stabilizes amyloid fibrils and therefore protects them from proteolytic degradation. METHODOLOGY/PRINCIPAL FINDINGS In this paper, we show that SAP binds not only to mature amyloid fibrils but also to early aggregates of amyl...

UNLABELLED Topiramate has emerged as one of the promising drugs for the treatment of alcoholism and alcohol addiction. Recent studies have shown that topiramate reduces harmful drinking and initiates abstinence in humans, but little is known as to why this drug is effective. AIMS In the present study, we examined the effects of topiramate in reducing convulsions during alcohol withdrawal usin...
