Previous studies have shown that electrical stimulation (ES) increases blood flow, but the exact mechanisms are not clear. The present study was designed to clarify some of the underlying mechanisms involved in this phenomenon. White adult rabbits Lt.-6 months old were used. Animals were anesthetized by sodium pentobarbital (40 mg/kg, IV) and skin blood flow in the thoracic back was recorde...

Introduction: Nitric oxide seems to play a dual role in ischemia/reperfusion injury. Few studies have investigated whether it exacerbates or improves brain edema. In the present study, we inhibited the activity of nitric oxide synthase by L-NAME and evaluated the cerebral infarct volume, tissue swelling and brain edema, alongside the measurement of blood flow of the ischemic region. Methods...

In this article, electro-thermo nonlocal nonlinear vibration and instability of viscous-fluid-conveying double–walled boron nitride nanotubes (DWBNNTs) embedded on Pasternak foundation are investigated. The DWBNNT is simulated as a Timoshenko beam (TB) which includes rotary inertia and transverse shear deformation in the formulation. Considering electro-mechanical coupling, the nonlinear govern...

Crumpled paper or drapery patterns are everyday examples of how elastic sheets can respond to external forcing. In this Letter, we study experimentally a different sort of forcing. We consider a circular flexible plate clamped at its center and subject to a uniform flow normal to its initial surface. As the flow velocity is gradually increased, the plate exhibits a rich variety of bending defor...

A new form of nystagmus is described in this paper: optic flow induced nystagmus (OFN). Optic field flow, for example when driving or viewing films on a large screen, triggered non-fatiguable upbeat nystagmus. This type of nystagmus could not be induced by vestibular stimuli, positioning, or self motion. The aetiology and anatomical correlate of OFN remains unknown. Treatment with gabapentin su...

Objective(s):Berberine, a naturally occurring isoquinoline alkaloid, has shown antitumor properties in some in vitro systems. But the effect of berberine on breast cancer has not yet been completely studied. In this study, we evaluated anticancer properties of berberine in comparison to doxorubicin. Materials and Methods: The antiproliferative effects of berberine and doxorubicin alone and in ...

cromolyn sodium, a mast cell stabilizing agent, provides an immediate protective effect against the exercise-induced bronchoconstriction while being used before the exercise. however, cromolyn is ineffective in reversing asthmatic bronchospasm; it is used as a maintenance therapy and has a prophylactic role in chronic asthma.    the purpose of this study was to determine the extent of change in...

in many acute leukemias, normal differentiation does not occur. however, in many cell lines derived from hematologic malignancies, differentiation or programmed cell death (apoptosis) can be induced by variety of agents including: vitamin analogs, demethylating agents, cyclic amp analogs and anti-proliferative agents. to the best of our knowledge there has been not any study specifically to ana...

objective: cervical cancer is the second most common cause of death from cancer in women throughout the world. the aim of this study was to evaluate the cytotoxic activity of kelussia odoratissima (k. odoratissima) extract associated with radiotherapy in cervical cancer cells (hela cell line).materials and methods: different concentration of the extract (25-500µg/ml) was tested in hela cell lin...
