Background: New-onset seizure can be potential life threatening condition. It raises the suspicion of intracranial abnormality or a primary epilepsy .These are mostly diagnosed and differentiated clinically, however diagnostic imaging has important role in evaluating cause . Previously studies done on neuroimaging seizures have focused assessment children adults acute emergency this study new o...

Vascular dilatation is critically impaired in many diseases and is encountered by an upregulated endothelin receptor A (ETA) in the vasculature in association with a decline in nitric oxide bioavailability. Diabetic vasculopathy is characterized as a compromised vascular dilatation, implicated in many diabetic complications. It appears to be activated ETA and NADPH (nicotinamide adenine dinucle...

Dysfunction of the BBB (blood-brain barrier) is a major hallmark of MS (multiple sclerosis). Studies in our laboratories over the last decade have shown that increased BBB permeability is associated with decreased expression of TJ (tight junction) proteins in brain capillary endothelial cells. Results have revealed that TJ abnormalities were most common in active lesions (42% of vessels affecte...

Lamina muscularis mucosae sitting beneath mucosal surface of the digestive tract has received little attention to date compared with external smooth muscle layers. Motor activity of the muscularis mucosae shows a great regional and species difference. Autonomic innervation profile is also different from esophagus to colon or between animal species. Intracellular transduction mechanisms for moto...

Rosacea is a chronic dermatological disorder with a variety of clinical manifestations localized largely to the central face. The unclear etiology of rosacea fosters therapeutic difficulty; however, subtle clinical improvement with pharmacologic treatments of various drug categories suggests a multifactorial etiology of the disease. Factors that may contribute to disease pathogenesis include im...

Although abnormal cell growth in arterial vessel walls underpins vascular remodeling in high blood pressure, the molecular basis of the abnormality in hypertension has not been fully defined. Here, we report that in the aorta of spontaneously hypertensive rats, telomerase is selectively activated and telomeres are lengthened, in vivo and in vitro. Down-regulation of telomerase, the ribonucleopr...

Interactions between endothelium and vascular smooth muscle cells play a major role in the biology of the blood vessel wall. Growth factors released from endothelial cells control in part the normal and pathological proliferation of vascular smooth muscle cells. Endothelial deposits of C5b-9 proteins, the membrane attack complex of complement (MAC), have been found in a variety of pathological ...

INTRODUCTION Hyperfamiliarity, a phenomenon in which feelings of familiarity are evoked by novel stimuli, is well described in epilepsy and the lesioned brain. Abnormality of familiarity in Alzheimer's disease (AD) and mild cognitive impairment (MCI) have also been described in the literature, but more from a neuropsychological approach perspective. Currently, there is a lack of study on the re...

A 49-year-old woman, suffering from peripheral vascular disease, was found to have two lipoprotein abnormalities, namely, type III hyperlipoproteinaemia and sinking prebeta lipoprotein. Twenty-one members of the kindred were investigated in an attempt to determine the pattern of inheritance of both of these abnormalities. In a 21-year-old son of the proband plasma electrophoresis was in keeping...

abstract : before initiating any endodontic therapy, probability of extra canals should be considered. the incidence of three canals in mandibular second premolar has been reported to be 0.46-0.5%. the present report describes nonsurgical endodontic treatment of three mandibular second premolars with three canals. in these cases, three orifices were located in mesiobuccal, distobuccal and lingu...
