Present investigation evaluates the protective effect of Melilotus officinalis (MO) extract on the brain tissues in acute cerebral ischemia. Acute cerebral ischemia was induced by occlusion of carotid artery and rats with cerebral ischemia were treated with MO (100, 250 & 500mg/kg) for the duration of three days. Cerebral ischemia was confirmed by estimating infract volume and neurological deficit score. Moreover biochemical parameters in plasma such as 6-keto-PGF1α and TXB2 and concentration of cytokine, oxidative stress, apoptosis ratio and protein expressions of Bcl2 & Bax were estimated in the brain tissues...

RATIONALE: The ischemic penumbra assessment is essential for the subsequent therapy and prediction of evolution in patients with acute ischemic infraction. Although controversial as a perfect equivalence to penumbra, perfusion-weighted imaging (PWI)-diffusion-weighted imaging (DWI) mismatch may predict the response to thrombolysis. Due to the reliance of PWI on contrast agents, noninvasive alternatives remain an unmet need. PATIENT CONCERNS: We reported a 65-year-old man complained of paroxysmal hemiplegia of his right limbs and anepia for 2 days, whereas the symptoms lasted for about 12 hours when he admitted to the hospital...

The term "Cotard's syndrome" is used to describe a number of clinical features, mostly hypochondriac and nihilistic delusions, the most characteristic of which are the ideas "I am dead" and "my internal organs do not exist". Besides, anxious and depressed mood, delusions of damnation, possession and immortality, suicidal and self-mutilating behavior are included. The first description of the syndrome was made in 1880 by Cotard, who presented the case of a female patient in a lecture. He originally named it "hypochondriac delusion", and some years later "delusion of negations", while it was named "Cotard delusion" after his death...

BACKGROUND Unequivocal brain radiation-induced parkinsonism has so far been reported in only in two pediatric patients. However, with the rising incidence rates for brain tumors in industrialized countries and the consequential increased exposure to cranial radiotherapy, clinicians might become more exposed to this entity. CASE REPORT Three patients were treated for intraparenchymal brain tumor with resection, chemotherapy, and whole brain radiation. One patient developed leukoencephalopathy and parkinsonism within one year of treatment, one developed it seven years after treatment completion, and one developed dementia, parkinsonism and cerebral infracts 40 years after whole brain radiation...

Ischemia contributes significantly to morbidity and mortality associated with many common neurological diseases. Calcium overload is an important mechanism of cerebral ischemia and reperfusion (I/R) injury. Despite decades of intense research, an effective beneficial treatment of stroke remains limited; few therapeutic strategies exist to combat the consequences of cerebral ischemia. Traditionally, a "neurocentric" view has dominated research in this field. Evidence is now accumulating that glial cells, especially astrocytes, play an important role in the pathophysiology of cerebral ischemia...

Sirtuin 2 (SIRT2) is a member of NAD(+)-dependent protein deacetylases involved in a wide range of pathophysiological processes including myocardial injury, Parkinson's disease, and Huntington's disease. However, the direct implication of SIRT2 in ischemic stroke is still unclear. In the present study, we observed that SIRT2 protein was mainly expressed in the cytoplasm of neurons, but not in astrocyte and microglia. SIRT2 was upregulated in ischemic neurons in the oxygen-glucose deprivation cell model and in the transient middle cerebral artery occlusion (tMCAo) mouse model...

Preconditioning exercise can exert neuroprotective effects after stroke. However, the mechanism underlying these neuroprotective effects by preconditioning exercise remains unclear. We investigated the neuroprotective effects of preconditioning exercise on brain damage and the expression levels of the midkine (MK) and brain-derived neurotrophic factor (BDNF) after brain ischemia. Animals were assigned to one of 4 groups: exercise and ischemia (Ex), no exercise and ischemia (No-Ex), exercise and no ischemia (Ex-only), and no exercise and intact (Control)...
