MRI phase imaging in multiple sclerosis (MS) patients and in autopsy tissue have demonstrated the presence of iron depositions in white matter lesions. The accumulation of iron in some but not all lesions suggests a specific, potentially disease-relevant process, however; its pathophysiological significance remains unknown. Here, we explore the role of(More)
A double blind cross over randomized study was conducted in 7 normal healthy volunteers. Single dose (700 mg) of buffered aspirin or aspirin with calcium carbonate or aspirin with caffeine was administered orally, at least 3 days apart. Blood samples were drawn at different time intervals after administration of drug for estimation of salicylate levels. The(More)
Postnatal day (P)20 rats are sensitive to CA1 injury following a single injection of kainic acid (KA) but are resistant to this injury when animals have a history of two neonatal seizures. We hypothesized that the two earlier seizures led to neuroprotection by a preconditioning mechanism. Therefore, morphology, [Ca(2+)](i) and NMDA subunit proteins of the(More)
In sheep, prenatal exposure to androgens during a critical period for sexual differentiation can masculinize tonic luteinizing hormone (LH) secretion and defeminize the LH surge. The present study investigated the possible independent control of these two modes of LH secretion, as revealed by their developmental history. Specifically, we tested the(More)
Rifampicin and pyrazinamide constitute an important part of drug regimens advocated for tuberculosis therapy, along with INH and streptomycin/ethambutol. The International Union against Tuberculosis and Lung Disease has also suggested the inclusion of these two drugs as part of short course chemotherapy for tuberculosis. Hence this study was undertaken to(More)
