BACKGROUND: The two main options for renal allograft preservation are static cold storage (CS) and machine perfusion (MP). There has been considerably increased interest in MP preservation of kidneys, however conflicting evidence regarding its efficacy and associated costs have impacted its scale of clinical uptake. Additionally, there is no clear consensus regarding oxygenation, and hypo- or normothermia, in conjunction with MP, and its mechanisms of action are also debated. The primary aims of this article were to elucidate the benefits of MP preservation with and without oxygenation, and/or under normothermic conditions, when compared with CS prior to deceased donor kidney transplantation...

BACKGROUND: Air injection is carefully avoided during IV solution administration; however, ambient air is dissolved in all liquids used for intravenous (IV) therapy. A portion of this gas will come out of solution in the form of bubbles as the solution is warmed to body temperature in a fluid warming system and/or within the body. We sought to quantify the proportion of the gas theoretically dissolved in room temperature crystalloid and 4°C blood products that comes out of solution in the IV tubing on warming to 37°C...

Runners are unlikely to consume fluid during training bouts increasing the importance of recovery rehydration efforts. This study assessed urine specific gravity (USG) responses following runs in the heat with different recovery fluid intake volumes. Thirteen male runners completed 3 evening running sessions resulting in approximately 2,200±300 mL of sweat loss (3.1±0.4% body mass) followed by a standardized dinner and breakfast. Beverage fluid intake (pre/post-breakfast) equaled 1,565/2,093 mL (low; L), 2,065/2,593 mL (moderate; M) and 2,565/3,356 mL (high; H)...

Identification of populations susceptible to heat effects is critical for targeted prevention and more accurate risk assessment. Fluid and electrolyte imbalance (FEI) may provide an objective indicator of heat morbidity. Data on daily ambient temperature and FEI emergency department (ED) visits were collected in Atlanta, Georgia, USA during 1993-2012. Associations of warm-season same-day temperatures and FEI ED visits were estimated using Poisson generalized linear models. Analyses explored associations between FEI ED visits and various temperature metrics (maximum, minimum, average, and diurnal change in ambient temperature, apparent temperature, and heat index) modeled using linear, quadratic, and cubic terms to allow for non-linear associations...

This study was aimed at determining the effect of oral administration of warm water during the postoperative initial stage on the time of first flatus in patients who had undergone laparoscopic cholecystectomy. In the literature, it is emphasized that warm water has favorable effects on intestinal movements such as "reliving gastrointestinal spasms and helping peristalsis return." This randomized controlled trial and experimental study was conducted in a university hospital between May and December 2011. In the study sample, we included a total of 60 patients; 30 were in the experimental group (drank warm water), while the other 30 composed the control group...

The presence of fetal calf serum in culture medium influences embryo quality, causing a reduction in postcryopreservation survival. Forskolin has been used to induce lipolysis and increase cryotolerance, functioning as an activator of adenylate cyclase and elevating cAMP levels. In the present experiment, bovine zygotes were cultured in synthetic oviduct fluid with amino acid plus 2.5% fetal calf serum for 6 days, when forskolin was added in three concentrations: 2.5, 5, and 10 μM. Treatment with forskolin lasted for 24 hours...

Hypothalamic oxytocin (OT) is released into the brain by cyclic ADP-ribose (cADPR) with or without depolarizing stimulation. Previously, we showed that the intracellular free calcium concentration ([Ca(2+)]i) that seems to trigger OT release can be elevated by β-NAD(+), cADPR, and ADP in mouse oxytocinergic neurons. As these β-NAD(+) metabolites activate warm-sensitive TRPM2 cation channels, when the incubation temperature is increased, the [Ca(2+)]i in hypothalamic neurons is elevated. However, it has not been determined whether OT release is facilitated by heat in vitro or hyperthermia in vivo in combination with cADPR...
