Cerebral white matter lesions (WMLs), due to small vessel disease, can be regarded as an early “silent” sign of hypertensive cerebral end-organ damage. As haptoglobin (Hp) phenotype has earlier been associated with symptomatic vascular disease, we now examined the relationship between Hp phenotype and asymptomatic cerebral small vessel disease, manifested by deep and periventricular WMLs, in hypertensive Read More

Neural progenitors cells are capable of promoting neurogenesis after ischemic stroke in the adult mammalian brain; however the function of these cells and their fate is still not clear. Therefore the purpose of this study investigated the relationship between neural progenitors and reactive astrocytes after middle cerebral artery occlusion (MCAO). Brain infarction was induced by occlusion of a right cerebral artery in male Wi Read More

Increasing evidence indicates that excessive iron in selective regions of the brain may be involved in the etiology of neurodegenerative disorders. Accordingly, increased levels of iron have been described in brain regions of patients in Parkinson's and Alzheimer's diseases. We have characterized neonatal iron loading in rodents as a novel experimental model that mimics the brain iron accumulation observed in patie Read More

The purpose of this study was to clarify the kinetics of nitric oxide (NO) induced by either endothelial NO synthase (eNOS) or neuronal NO synthase (nNOS) after transient global forebrain ischemia. We investigated NO production and ischemic changes to hippocampal CA1 neurons in eNOS knockout (-/-) mice and nNOS (-/-) mice during cerebral ischemia and reperfusion. NO production was continuously monitored by in vivo Read More

Neurotransmitters catechol and dopamine analogy levels are related to the systematic nerve activity. This assay was performed by using cyclic voltammetry (CV) and square wave (SW) stripping voltammetry, while optimization was performed by the carbon fiber microelectrode (CFME) with wire-type reference and counter electrodes. In the electrolyte solutions, the analytical parameters of catechol were as follows: 8.5 pH, - Read More

Subarachnoid hemorrhage (SAH) develops when extravasated arterial blood enters subarachnoid space and mixes with cerebrospinal fluid. As a result, many pathologies develop, including increase in brain-blood barrier (BBB) permeability and activation of peripheral leukocytes, that in turn augment immuno-inflammatory response, considered as the cause of numerous complications following SAH. In the study, we examine Read More

The use of mesenchymal stem cells (MSCs) has been shown to be promising in chronic disorders such as diabetes, Alzheimer's dementia, Parkinson's disease, spinal cord injury and brain ischemia. Recent studies revealed that human tooth germs (hTG) contain MSCs which can be easily isolated, expanded and cryo-preserved. In this report, we isolated human tooth germ stem cells (hTGSCs) with MSC characteristics from Read More

Diabetes mellitus (DM) impacts a significant portion of the world's population and care for this disorder places an economic burden on the gross domestic product for any particular country. Furthermore, both Type 1 and Type 2 DM are becoming increasingly prevalent and there is increased incidence of impaired glucose tolerance in the young. The complications of DM are protean and can involve multiple systems throughou Read More
