The whole plant of Biophytum petersianum was extracted with a mixture of water – alcohol (1:1) to evaluate its relaxant effect on aorta rings. In isolated Wistar rat tissue, the hydro-ethanolic extract (0.1; 0.25 and 0.5 mg/ml) non-competitively antagonized calcium chloride and high-K + - induced aorta contractions in a concentration-dependent manner. Moreover, the inhibition of noradr...

Despite its widespread use, high-resolution imaging with multiphoton microscopy to record neuronal signals in vivo is limited to the surface of brain tissue because of limited light penetration. Moreover, most imaging studies do not simultaneously record electrical neural activity, which is, however, crucial to understanding brain function. Accordingly, we developed a photometric patch electrod...

Objective(s):   Recently, applications of MnO2 nanoparticles and microparticles in industry, pharmacology, and medicine have considerably expanded. Mn distribution and clearance from brain and spinal cord tissue compared with muscle tissue of rats after single subcutaneous injection of nanoparticles and microparticle of MnO2. Pain sensory threshold of rat was evaluated as neurologic consequence...

Studies indicate that diet and vascular calcification may be related to the occurrence of brain lesions, although the importance of dietary calcium and vitamin D has not been investigated. The objective of this study was to test the hypothesis that calcium and vitamin D intakes would be positively associated with brain lesion volumes in elderly individuals with and without late-life depression....

neuroinflamation occurring after traumatic brain injury (tbi) is a complex phenomenon comprising distinct cellular and molecular events involving the injured cerebral tissue. mechanical injury to adult rat brain elucidated the accumulation in the affected area of trophic activity. in the tissue adjacent to the injury, trophic titers began to rise after the lesion. this study aimed to determine ...
