The hypothesis that nexuses between cells are responsible for the core conductor properties of tissues was tested using smooth muscle preparations from the taenia coli of guinea pigs. Action potentials recorded from small diameter preparations across a sucrose gap change from monophasic to diphasic when a shunt resistor is connected across the gap. This indicates that transmission between smoot...

An analytical model based on an equivalent capacitance circuit for expressing a static effective permittivity of a composite dielectric with complex-shaped inclusions is presented. The dielectric constant of 0–3 composites is investigated using this model. The geometry of the capacitor containing a composite dielectric is discretized into partial parallel-plate capacitor elements, and the effec...

Introduction and Aim: Brucellosis is an important zoonotic disease caused by Brucella spp. which intracellular gram-negative bacterium. melitensis lacks the "traditional" virulence factors such as exotoxins or cytolysins, but capable of persisting intracellularly evading immune system. This study aims to identify B. using PCR discover genes associated with its severity for early detection thera...

introduction: the pagat polymer gel dosimeter melts at 30 ˚c and even at room temperature during the summer, so it needs to be kept in a cool place such as a refrigerator. to increase the stability of the pagat gel, different amounts of agarose were added to the pagat gel composition and the pagata gel was manufactured. material and methods: the pagata gel vials were irradiated using a co-60 ma...

conclusions our successful extraction of purified lps from e. coli isolates of uti patients’ urine samples can be an important step to understand the uti disease conditions. results the silver-stained gel demonstrated both smooth and rough type lps by showing trail-like band patterns with the presence and lacking o-antigen region, respectively. coomassie blue staining showed no band assuring th...

a slow diphasic wave occurring between the atrial electrogram (P) and the H potential. It is characterized by slurring or notching on the upstroke. The H potential, as previously described, is a biphasic or triphasic wave of 15 to 20-msec duration. The RB potential is a fast biphasic wave of 10 to 20-msec duration occurring between the H potential and the Q wave. During single atrial pacing and...

The clinical description of periodic catatonia is well documented by the earliest exponents of psychiatry. Gjessing (1935) carried out extensive metabolic and clinical studies in cases of periodic catatonia. He reported diphasic course of nitrogen metabolism associated with periodic mental changes and described 3 types of syntonic synchronous (S.S.) periodic catatonias, Type A, B and C. (Gjessi...
