We have previously reported that Chinese traditional medicine rutaecarpine (Rut) produced a sustained hypotensive effect in phenol-induced and two-kidney, one-clip hypertensive rats. The aims of this study are to determine whether Rut could exert antihypertensive and anti-platelet effects in spontaneously hypertensive rats (SHR) and the underlying(More)
Previous studies have shown that the endogenous nitric oxide synthase inhibitor asymmetric dimethylarginine (ADMA) and its specific hydrolase dimethylarginine dimethylaminohydrolase (DDAH) are involved in the regulation of apoptosis in different cell types. In the present study, we investigated the role of the DDAH/ADMA pathway in cobalt chloride(More)
Freeman and Baird [5; Freeman WJ, Baird B. Behav Neurosci 1987;101:393-408] recorded from the surface of the brain in waking rabbits and found spatial patterns of voltage that covaried with sensory experience. We simulate mathematically the electric fields produced by radial dipoles in cortical gyri and show that patterns with the spatial frequencies(More)
The common marmoset (Callithrix jacchus) is a New World primate sharing many similarities with humans. Recently developed technology for generating transgenic marmosets has opened new avenues for faithful recapitulation of human diseases, which could not be achieved in rodent models. However, the longer lifespan of common marmosets compared with rodents may(More)
Modeling of neurological diseases using induced pluripotent stem cells (iPSCs) derived from the somatic cells of patients has provided a means of elucidating pathogenic mechanisms and performing drug screening. T cells are an ideal source of patient-specific iPSCs because they can be easily obtained from samples. Recent studies indicated that iPSCs retain(More)
In t(14;18)-positive lymphoma cells, bcl-2 is expressed from a fusion mRNA transcript containing the full coding sequence of bcl-2 and 3' immunoglobulin sequences. We reported previously that antisense oligodeoxyribonucleotides directed at the bcl-2 translational start site, as well as those targeted to immunoglobulin sequences 3' of the translocation(More)
There are significant morphological and biochemical alterations during nerve growth factor (NGF)-promoted neuronal differentiation, and the process is regulated by molecules, including nitric oxide (NO). Dimethylarginine dimethylaminohydrolase (DDAH) is thought to play a critical role in regulating NO production via hydrolyzing the endogenous NO synthase(More)
Previous studies have shown that the injection of estrogen into immature rats leads to an influx of leukocytes into the uterus. Using immunoperoxidase staining and monoclonal antibodies, we have characterized the nature of the infiltrating leukocytes in frozen sections of immature rat uteri obtained following the injection of estrogen, estrogen plus(More)
Conscious rats treated with bolus endotoxin (ET; 4.0 mg/kg) increased plasma epinephrine (Epi) 48-fold (from 134 +/- 5 to 6,545 +/- 1,607 pg/ml) at 30 min, but by 6 h this elevation was less than 9-fold above control (1,174 +/- 166 pg/ml). In contrast, plasma norepinephrine (NE) elevation (6.5-fold above control) was maintained during the protocol. The(More)
