The human motor cortex has a tendency to resonant activity at about 20 Hz so stimulation should more readily entrain neuronal populations at this frequency. We investigated whether and how different interneuronal circuits contribute to such resonance by using transcranial magnetic stimulation (TMS) during transcranial alternating current stimulation (tACS) at motor (20 Hz) and a nonmotor resona...

BACKGROUND Asclepias curassavica Linn. is a traditional medicinal plant used by tribal people in the western ghats, India, to treat piles, gonorrhoea, roundworm infestation and abdominal tumours. We have determined the protective effect of beta-sitosterol isolated from A. curassavica in colon cancer, using in vitro and in vivo models. METHODS The active molecule was isolated, based upon bioas...

We recently reported the synthesis and anti-inflammatory properties of a novel long chain polyunsaturated fatty acid (PUFA) with an oxygen atom in the beta-position, beta-oxa-21:3 n-3 (Z,Z,Z)-(octadeca-9,12,15-trienyloxy) acetic acid). Our data, from studies aimed at elucidating the mechanism of its action, show that pretreatment of human neutrophils with the beta-oxa-PUFA substantially depress...

A series of micro-mesoporous zeolitic catalysts synthesized using recrystallization two different zeolites (HZSM-5 and beta) were impregnated with Pt other notable metals. The resulting bifunctional characterized tested for the hydrocracking a model municipal waste plastic mixture. Actual mixture same composition was also employed comparison. experiments carried out in Parr stirred batch reacto...

Background Patients with beta thalassemia suffer from increased susceptibility to infections and putridity plays a major role in the patient's morbidity and mortality. The risk of transfusion-transmitted viral infection is well known in these patients. However, there is dearth of information about the seroprevalence of herpes simplex virus (HSV) infection in patients with beta thalassem...

The ab-initio theory of charge transport in semiconductors typically employs the lowest-order perturbation which electrons interact with one phonon (1ph). This is accepted to be adequate explain low-field mobility non-polar but has not been tested extensively beyond regime. Here, we report first-principles calculations electric field-dependence electron Si as described by warm coefficient, $\be...
