1. Eleven nephrotic patients were immersed up to the neck in 1.3 m of water at 34 degrees C for 4 h. 2. A diuresis began, within the first hour of, and continued throughout, immersion. The urine osmolality fell significantly and decreased to hypotonic levels in the first hour of immersion and increased gradually during the remainder of immersion and postimmersion. 3. Throughout immersion there ...

Cold thermoregulatory models (CTM) have primarily been developed to predict core temperature (T(core)) responses during sedentary immersion. Few studies have examined their efficacy to predict T(core) during exercise cold exposure. The purpose of this study was to compare observed T(core) responses during exercise in cold water with the predicted T(core) from a three-cylinder (3-CTM) and a six-...

The effects of fluoride, which is present in different oral hygiene products, deserve more investigation because little is known about their impact on the surface of titanium, which is largely used in Implantology. This study evaluated the surface of commercially pure titanium (cpTi) after exposure to different concentrations of sodium fluoride (NaF). The hypothesis tested in this study was tha...

Chemical disinfectants are usually associated with mechanical methods to remove stains and reduce biofilm formation. This study evaluated the effect of disinfectants on release of metal ions and surface roughness of commercially pure titanium, metal alloys, and heat-polymerized acrylic resin, simulating 180 immersion trials. Disk-shaped specimens were fabricated with commercially pure titanium ...

The "mediated sense of presence" is a technology-induced illusion of being present in one (simulated) place when one is actually present in another (physical) place. Typically experienced in virtual worlds, mediated presence is generated by different technological, cognitive, and emotional factors. The aim of this study was to test how to optimise the virtual experience by manipulating some of ...

Pleiotrophin (PTN) is a growth factor that exhibits neurotrophic actions and is upregulated at sites of nerve injury. Upregulation of PTN levels in injured dorsal root ganglion correlates with decreased mechanical allodynia and faster recovery from Chronic Constriction Injury of the rat sciatic nerve. Despite the evidence pointing to a role of PTN in the development of chronic pain, the role of...

Cnidoscolus quercifolius is a common plant species with multiple uses from Brazilian semiarid area (BSA). Their seeds have dormancy. Fact that needs to be resolved in favor of the growing demand produce seedlings this species, mainly for recovery degraded areas BSA. Non-acidic technologies such as water immersion and ultrasound are testing promote uniform emergence vigor many species. The objec...
