Introduction: Stress is a main factor influencing brain functions as revealed by the electroencephalogram (EEG) recordings. Moreover, different stress durations seemingly cause perturbations in brain waves and lead to mental disorders. This study investigates the effects of acute, sub-chronic and chronic stress on EEG in rats.  Methods: Twenty-eight Wistar adult male rats were randomly all...

neuroinflammation as a protective mechanism for repairing tissue damage in the central nervous system (cns), has been classified into two types: acute and chronic. it is characterized by the activation of microglia and astrocytes and the increase levels of different chemokines and cytokines. neuroinflammation can be harmful, and it is a common pathological feature in neurodegenerative and psych...

Background: Astronauts will be exposed to both chronic space radiation and acute high doses of energetic radiation of solar particle events in long-term deep space missions. The application of radioprotectors in space missions has basic limitations such as their very short time window as well as their acute toxicity and considerable side effects. The aim of the present study was to investigate ...

On the other hand, the concentration of total plasma homocysteine (Hcy) is a well-established indicator for the risk of cardiovascular disease and seems to be related to ethanol consumption. So, the aim of...

background: the assays currently available for the detection of specific anti- toxoplasma antibodies may vary in their abilities to detect serum immunoglobulins, due to the lack of a purified standardized antigen. the aim of this study was evaluation the recombinant toxoplasma gondii sag1 antigen for the serodiagnosis of acute and chronic toxoplasmosis. methods : this study describes an elisa u...
