Populations of widely distributed ectotherms demonstrate different cold resistance corresponding to the local climate. However, efficiently thermoregulating ectotherms could avoid divergence in cold resistance. Two species of ants, previously shown to even out latitudinal differences of mean summer temperatures in their nests, were used to test this hypothesis by comparing the temperature depen...

AIMS To investigate the lagged effects of cold temperature on cardiorespiratory mortality and to determine whether "wind chill" is a better predictor of these effects than "dry bulb" temperature. METHODS Generalised linear Poisson regression models were used to investigate the relation between mortality and "dry bulb" and "wind chill" temperatures in the three largest Scottish cities (Glasgow...

Reducing core temperature to protect the injured brain has become a new therapeutic measure. The scientific underpinnings based on animal experiments seem sound. Evidence of the therapy's effect in human trials is insufficient or even possibly absent, but the techniques to produce moderate hypothermia are available, without apparent significant complications, and are relatively easy to use for ...

Prostate cancer (PCa) is one of the most frequently diagnosed cancers in developed countries. Several studies suggest that variations in calcium homeostasis are involved in carcinogenesis. Interestingly, (Transient Receptor Potential Melastatin member 8) TRPM8 calcium permeable channel expression is differentially regulated during prostate carcinogenesis, thereby suggesting a potential function...

This article proposes and presents a novel approach to the characterization of winter precipitation and modeling of radar observables through a synergistic use of advanced optical disdrometers for microphysical and geometrical measurements of ice and snow particles (in particular, a multi-angle snowflake camera—MASC), image processing methodology, advanced method-of-moments scattering computati...

One of the methods used to surface hardening ductile iron is chilled cast iron. Chill as fast cooling rate in mold during solidification and chill thickness greatly affects hardness layer. The main material iron, SS 304. Casting uses sand casting method. Before pouring, plate has been inserted onto pattern that formed mold, then preheated at 700°C. Pouring was carried out a melting temperature ...

background: it is now well-demonstrated that histone demethylases play an important role in developmental controls, cell-fate decisions, and a variety of diseases such as cancer. lysine-specific demethylase 5d (kdm5d) is a male-specific histone demethylase that specifically demethylates di- and tri-methyl h3k4 at the start site of active genes. in this light, the aim of this study was to invest...
