Sepsis-induced changes in behavioral stereotypy in rats; involvement of tumor necrosis factor-alpha, oxidative stress, and dopamine turnover.

Only registered users can translate articles

BACKGROUND Sepsis-associated encephalopathy (SAE) is defined as a diffuse or multifocal cerebral dysfunction that generally occurs early during severe sepsis. The complete pathophysiology of SAE is unknown, but several mechanisms including endotoxins, inflammatory mediators, the alteration of amino

Calcification and uptake of Tc-99m diphosphonates in neuroblastomas: concise communication.

Only registered users can translate articles

Sixty-six percent of 54 patients with neuroblastoma demonstrated uptake of bone-seeking radioagents by the primary tumor. This is a higher incidence than previously reported. Uptake was slightly more common in abdominal than thoracic tumors. There was a significant correlation between the size of

Stress at work alters serum brain-derived neurotrophic factor (BDNF) levels and plasma 3-methoxy-4-hydroxyphenylglycol (MHPG) levels in healthy volunteers: BDNF and MHPG as possible biological markers of mental stress?

Only registered users can translate articles

There is growing evidence that blood levels of brain-derived neurotrophic factor (BDNF) and catecholamine, and cytokines are related to not only to depressive, suicidal, and anxious states but also to depression-associated personality traits. Psychological job stress is well known to lead to

Gamma Oryzanol Alleviates High-Fat Diet-Induced Anxiety-Like Behaviors Through Downregulation of Dopamine and Inflammation in the Amygdala of Mice.

Only registered users can translate articles

A high-fat diet (HFD) can induce obesity and metabolic disorders that are closely associated with cognitive impairments, and the progression of several psychiatric disorders such as anxiety. We have previously demonstrated the anxiolytic-like effect of Gamma oryzanol (GORZ) in chronic

The neuroprotective efficacy of alpha-crystallin against acute inflammation in mice.

Only registered users can translate articles

Acute inflammation activates macrophages or monocytes and subsequently releases several inflammatory cytokines and reactive oxygen and nitrogen species. These proinflammatory cytokines activate astrocytes and trigger neurodegenerative diseases. In this work, we chose to address the mechanistic

Age influences abnormalities in striatal dopamine metabolism during and after transient forebrain ischemia.

Only registered users can translate articles

Age has been found to be a significant risk factor for brain ischemia and its mortality. After cerebral ischemia, the nigrostriatal dopaminergic system undergoes selective vulnerability with necrosis of striatal neurons. To study the effect of age and transient forebrain ischemia on striatal

Stereotaxic microinjection of HSV-1 selectively decreases striatal dopamine concentrations in mice.

Only registered users can translate articles

BALB/c mice were stereotaxically injected in the striatum with either the MP or MacIntyre strain of herpes simplex type 1. Three days later, at a time when the animals were free from overt signs of infection, they were killed by cervical dislocation and the striatum was rapidly removed.

Kainic acid induced seizures: neurochemical and histopathological changes.

Only registered users can translate articles

Behavioural, histopathological and neurochemical changes induced by systemic injection of kainic acid (10 mg/kg, s.c.) were investigated in rats. The most pronounced behavioural changes were strong immobility ("catatonia"), increased incidence of "wet dog shakes", and long-lasting generalized

Antioxidative and anti-inflammatory protection from carnosine in the striatum of MPTP-treated mice.

Only registered users can translate articles

Mice treated with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) were used to examine the neuroprotective effects of carnosine. Carnosine at 0.5, 1, and 2 g/L was directly added to the drinking water for 4 weeks. MPTP treatment significantly depleted striatal glutathione content, reduced the

Neuroprotective efficiency of Mangifera indica leaves extract on cadmium-induced cortical damage in rats.

Only registered users can translate articles

Due to the high ability of cadmium to cross the blood-brain barrier, cadmium (Cd) causes severe neurological damages. Hence, the purpose of this study was to investigate the possible protective effect of Mangifera indica leaf extract (MLE) against Cd-induced neurotoxicity. Rats were divided into

Relationships between serum brain-derived neurotrophic factor, plasma catecholamine metabolites, cytokines, cognitive function and clinical symptoms in Japanese patients with chronic schizophrenia treated with atypical antipsychotic monotherapy.

Only registered users can translate articles

Catecholamines, brain-derived neurotrophic factor (BDNF) and cytokines may be involved in the pathophysiology of schizophrenia. The aim of this study was to examine the associations between serum BDNF levels, plasma catecholamine metablolites, cytokines and the cognitive functions of patients with

Clinical and biological predictors of response to electroconvulsive therapy (ECT): a review.

Only registered users can translate articles

Electroconvulsive therapy (ECT), developed in the 30's by Bini and Cerletti, remains a key element of the therapeutic armamentarium in psychiatry, particularly for severe and life-threatening psychiatric symptoms. However, despite its well-established clinical efficacy, the prescription of ECT has

Simvastatin prevents 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced striatal dopamine depletion and protein tyrosine nitration in mice.

Only registered users can translate articles

Parkinson's disease is a neurological disorder involving the progressive loss of dopaminergic neurons in the substantia nigra pars compacta. There is increasing evidence that inflammation plays a role in the propagation of neurodegenerative processes in Parkinson's disease. We investigated the

Chrysin protects against behavioral, cognitive and neurochemical alterations in a 6-hydroxydopamine model of Parkinson's disease.

Only registered users can translate articles

Parkinson's disease (PD) is an age-related neurodegenerative disorder that severely affects quality of life of patients and their families. The flavonoid chrysin (5,7-dihydroxylflavone) is a naturally occurring flavone with several pharmacological activities, including anti-inflammatory and

Naringenin Decreases α-Synuclein Expression and Neuroinflammation in MPTP-Induced Parkinson's Disease Model in Mice.

Only registered users can translate articles

The present study was designed to ascertain the role of naringenin (NGN), a citrus fruit flavanone, against 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced α-synuclein (SYN) pathology and neuroinflammation in a mouse model. NGN was administered to C57BL/6J mice once a day for 5
