Major depression is a common, serious and recurrent disorder that affects 17-20% of the population of the world. The chronic mild stress (CMS) model has been used as an animal model of depression but reflect anhedonia in animals. Present study investigated behavioral, physiological and neurochemical aspects of rats exposed to a CMS procedure. The consumption of sweet food, locomotor activity, body and adrenal gland Read More

Stroke is accompanied by a strong inflammatory reaction in the brain. Periodontal disease is a chronic local infection which causes a systemic low grade inflammation. We hypothesized that a mild systemic inflammatory reaction as caused by periodontal disease prior to stroke onset, may exert a neuroprotective effect in a rat model of focal ischemia. To test this hypothesis, marginal periodontitis was induced by ligatures on the s Read More

Gender hormones are associated with the evolution of Multiple Sclerosis (MS) like changes in experimental models of MS. Several clinical studies have attempted to elucidate the role of gender hormones in the evolution of the clinical spectrum of the disease. We attempt to describe the currently known data regarding such associations emphasizing the potential clinical applications in different MS scenarios i.e. pregnancy, Read More

Vascular endothelial growth factor (VEGF) and angiopoietin-1 (Ang1) were originally identified as endothelial-specific ligands regulating key functions of the vasculature important in stroke. There is increasing evidence that these ligands also exert effects on neurons. Here we review the neuronal effects of VEGF and Ang1 and highlight their potential for therapeutic manipulation in stroke. VEGF stimulates angiogenesis wh Read More

Vascular Endothelial Growth Factor (VEGF) is recognized as a central factor in growth, survival and permeability of blood vessels in both physiological and pathological conditions. It is as such of importance for vascular responses in various central nervous system (CNS) disorders. Accumulating evidence suggest that VEGF may also act as a neuroprotective and neurotrophic factor supporting neuronal survival and n Read More

Physiologic functioning of the cerebrovenous system is indispensable for maintaining normal brain function. However, in contrast to the cerebroarterial system, the cerebral venous return is not routinely investigated. Combined high-resolution echo-colour-Doppler (ECD) and transcranial colour coded Doppler sonography (TCCS) represents an ideal method to investigate the haemodynamics of cerebral venous Read More

Alcohol one of the important products of the global addiction alters brain function by interacting with multiple neurotransmitter systems, thereby disrupting the delicate balance between inhibitory and excitatory neurotransmitters. Alcohol positively reinforces drinking by producing a mild euphoria. The reinforcing effects of alcohol are mediated by several neurochemical systems and are associated with some of the behavi Read More
