Efficient cell electrotransfection can be achieved using combinations of high-voltage (HV; 800 V/cm, 100 micros) and low-voltage (LV; 80 V/cm, 100 ms) pulses. We have developed equipment allowing the generation of various HV and LV combinations with precise control of the lag between the HV and LV pulses. We injected luciferase-encoding DNA in skeletal muscle, before or after pulse delivery, an...

Abstract Reconstructing a discrete object by means of X-rays along finite set U (discrete) directions represents one the main task in tomography. Indeed, it is an ill-posed inverse problem, since different structures exist having same projections all lines whose range . Characteristic ambiguous reconstructions are special configurations, called switching components, understanding issue tomograp...

Background Lack of habituation of visual evoked potentials (VEP) is a common finding in migraine patients between attacks. Previous studies have suggested an electrophysiological familial aggregation pattern associated with migraine. The aim of this study was to evaluate the influence of a positive familial history of migraine on VEP amplitude and habituation. Methods We recorded six blocks of ...

A newly developed phenoxyalkylamine derivative, 2-isopropyl-5-[3-(2-methoxyphenoxy)propylamino]-2-(3,4, 5-trimethoxyphenyl)-valeronitrile fumarate (HV-525), was investigated in intact dogs and in isolated dog atria perfused with anesthetized donor dog's arterial blood. When 0.3 mg/kg of HV-525 was intravenously administered to the donor dog, a depressor effect without significant changes in hea...

Volatility is the key of the option price in the stock market. Changes in volatility will dramatically lead to changes of the option price. One of the most important volatilities is historical volatility (HV ). The HV is essentially the annualized standard deviation of the first order difference of logarithm of the asset price. Therefore, changes in HV in finance may be detected by the variance...

BACKGROUND Klebsiella pneumoniae (KP) expressing hypermucoviscosity phenotype (HV-KP) has abundant capsular polysaccharide (CPS) and is capable of causing invasive syndrome. Sodium salicylate (SAL) reduces the production of CPS. The study was aimed to investigate the relationship between aspirin usage and KP-mediated invasive syndrome and the effect of SAL on HV-KP. METHODS Patients with comm...
