Background: Corn silk (CS) is widely used in Iranian traditional medicine and Feijoa sellowiana(FS) is a native plant widespread in the Southern parts of Iran. The aim of the present study was to assess renal protective activities of CS and FS against dosage induced injury by ecstasy (MDMA) using insitu rat renal perfusion (IRRP) system.Methods: Hydro-alcoholic extract of CS and FS (10, 20, 40 ...

Normal operations of the neocortex depend critically on several types of inhibitory interneurons, but the specific function of each type is unknown. One possibility is that interneurons are differentially engaged by patterns of activity that vary in frequency and timing. To explore this, we studied the strength and short-term dynamics of chemical synapses interconnecting local excitatory neuron...

In the present paper we introduce and study the notion of pairwise weakly Lindelof bitopological spaces and obtain some results. Further, we also study the pairwise weakly Lindelof subspaces and subsets, and investigate some of their properties. It was proved that a pairwise weakly Lindelof property is not a hereditary property.

An actively debated issue in the experimental study of high-Tc cuprate superconductors [1,11,16] is the symmetry and detailed k-dependence of the gap function ∆k. We suggest a form of ∆k, based on physical arguments and numerical results, which is in qualitative agreement with the available experimental results. The form that we suggest is a generalised version of an early suggestion of Anderso...

Our previous finding and the given mechanism of charge and electron transfer in polypeptides are here integrated in a bifunctional model involving electronic charge transfer coupled to special internal rotations. Present molecular dynamics simulations that describe these motions in the chain result in the mean first passage times for the hopping process of an individual step. This "rest and fir...

Our objective was to compare self-reported health-related quality of life (HRQOL) for U.S. veterans with multiple sclerosis (MS) on disease-modifying agents with provider reports of HRQOL from standard disability measures. We conducted a 3-year prospective observational study of 204 subjects who used interferon beta or glatiramer acetate and compared subjects' responses on the Veterans Short-Fo...

BACKGROUND The purpose of the study was to measure the retinal venous pressure (RVP) in the eyes of primary open-angle glaucoma (POAG) patients and healthy subjects with and without a Flammer-Syndrome (FS). METHODS RVP was measured in the following four groups of patients and age- and sex-matched healthy controls: (a) 15 patients with a POAG and a FS (POAG/FS+); (b) 15 patients with a POAG bu...

The primary all-trans --> 13-cis photoisomerization of retinal in bacteriorhodopsin has been investigated by means of quantum chemical and combined classical/quantum mechanical simulations employing the density matrix evolution method. Ab initio calculations on an analog of a protonated Schiff base of retinal in vacuo reveal two excited states S1 and S2, the potential surfaces of which intersec...

Selective targeting of diseased cells can increase therapeutic efficacy and limit off-target adverse effects. We developed a new tool to selectively perforate living cells with functionalized gold nanoparticles (AuNPs) and near-infrared (NIR) femtosecond (fs) laser. The receptor CD44 strongly expressed by cancer stem cells was used as a model for selective targeting. Citrate-capped AuNPs (100 n...
