The Valsalva maneuver, named after Antonio Maria Valsalva, is one of the vagal maneuvers.It is defined as a forced expiration against a closed glottis, leading to an increase in intrathoracic and intra-abdominal pressure.Over the years it has become a subject of interest to many clinical researchers who have comprehensively studied its physiology a
The rate of hydrolysis of hydrolysis of ethyl benzoate were measured volumetric over the temperature range of 200c to 400c.in water-methanol mixture at different composition.The different solvation in initial and transition state is due to L-Arginine decrease in rate with varying the composition of mixture.The influence of solvent on reaction rate
The persistence of virtually every single species depends on both the presence of other species and the specific environmental conditions in a given location.Because in natural settings many of these conditions are unknown, research has been centered on finding the fraction of possible conditions (probability) leading to L-Arginine species coexiste
Supported lipid bilayers (SLBs) are low-complexity biomimetic membranes, serving as popular experimental platforms to study membrane organization and lipid transfer, membrane uptake of nanoparticles and biomolecules, and many other processes.Quartz crystal microbalance with dissipation monitoring has been utilized to probe the Tights influence of s
Abstract Background Floating right heart thrombi (RHT) represent an underdiagnosed, potentially hazardous, and to some extent rare phenomenon in patients presenting with acute pulmonary embolism (APE).Emergent treatment is usually required for such a condition.Case presentation A 19-year-old young lady presented with progressive shortness of breath
