HeLa cells infected with several group B coxsackieviruses contain a previously undetected, virus-specific ribonucleoprotein particle which we designated membrane-bound virion (MBV). MBVs of B5 virus have a pronounced polygonal appearance and are slightly smaller than virions. The particles sediment more slowly (at about 107S) and have a lower buoyant density (about 1.30). They contain 35S virio...

The tensor virial theorem for subsystems is formulated for threecomponent systems and further effort is devoted to a special case where the inner subsystems and the central region of the outer one are homogeneous, the last surrounded by an isothermal homeoid. The virial equations are explicitly written under the additional restrictions: (i) similar and similarly placed inner subsystems, and (ii...

We introduce a newsgathering system that features high mobility and wide-area coverage: Mobile Broadcasting Video (MBV) system. According to the original design concept, this system’s transmission channels provide increased mobility and wide area coverage, utilizing wireless LAN and low-orbit satellite technology. Also this system provides audiovisual quality that is comparable to current digit...

Objective. The main purpose of the research was to develop a coefficient cardiorespiratory system status, which will take into account both frequency and power characteristics external respiration hemodynamics activity. Compare an informativeness this with universally accepted Hildebrandt one.
 Materials Methods. 154 apparently healthy young people sexes were examined. On bicycle ergometer...

The hypothesis that upright posture could modulate forearm blood flow (FBF) early in exercise was tested in six subjects. Both single (2-s duration) and repeated (1-s work/2-s rest cadence for 12 contractions) handgrip contractions (12 kg) were performed in the supine and 70° head-up tilt (HUT) positions. The arm was maintained at heart level to diminish myogenic effects. Baseline brachial arte...

The contributions of acetylcholine and/or nitric oxide (NO) to the rapid changes in human forearm blood flow (FBF) at the onset and recovery from mild exercise were studied in eight subjects. Rhythmic handgrip contractions were performed during brachial artery infusions of saline (2 ml/min; control), atropine (0.2 mg over 3 min), to block acetylcholine binding to muscarinic receptors, or atropi...

BACKGROUND White spot disease (WSD), a major threat to sustainable aquaculture worldwide, is caused by White spot syndrome virus (WSSV). The diagnosis of WSD relies heavily on molecular detection of the virus by one-step PCR. These procedures are neither field-usable nor rapid enough considering the speed at which the virus spreads. Thus, development of a rapid, reliable and field-usable diagno...

It has been demonstrated that insulin's vascular actions contribute to regulation of insulin sensitivity. Insulin's effects on muscle perfusion regulate postprandial delivery of nutrients and hormones to insulin-sensitive tissues. We here describe a technique for combining intravital microscopy (IVM) and contrast-enhanced ultrasonography (CEUS) of the adductor compartment of the mouse hindlimb ...
