Annual Sainfoin (Onobrychis crista-galli (L.) Lam.) is widely adapted to moderate and cold regions of Iran and naturally grows in pasture and rangelands used for forage in these areas. In order to study the effects of priming on seed germination and seedling growth in O. crista-galli, two factorial experiments were conducted based on a randomized complete design with three replications under la...

We studied habituation processes by exposing six healthy men to cold air (2 h in a 10 degrees C room) daily for 11 days. During the repeated cold exposures, the general cold sensations and those of hand and foot became habituated so that they were already significantly less intense after the first exposure and remained habituated to the end of the experiment. The decreases in skin temperatures ...

• Drinking cold water evokes decreases in spirometric indices of lung function We studied if this may be explained by changes exhaled-breath temperature (EBT), flow dynamics, and spirometer measurement EBT falls significantly below baseline following cold-water ingestion The decrease was calculated to influence pneumotachograph measurements < 1% Accordingly, decreased likely has a physiological...

Within ongoing work, Canada’s Nuclear Waste Management Organization (NWMO) is demonstrating that copper coatings can be developed as viable corrosion barriers for used fuel nuclear containers, emplaced in a deep geological repository. As a means of assessing container design and feasibility, coated samples, manufactured via cold spray and electrodeposition have been produced and characterised. ...

Various therapeutic approaches for dysphagia management are based on modifications of bolus properties to change swallowing biomechanics and increase swallowing safety. Limited evidence exists for the effects of carbonation and bolus temperature on swallowing behavior. Here, we investigated the effects of carbonation and temperature on swallowing behavior using a novel automated and complex swa...

Chen, Gin-Fu, and Zhongjie Sun. Effects of chronic cold exposure on the endothelin system. J Appl Physiol 100: 1719–1726, 2006. First published December 29, 2005; doi:10.1152/japplphysiol.01407.2005.— Cold temperatures have adverse effects on the human cardiovascular system. Endothelin (ET)-1 is a potent vasoconstrictor. We hypothesized that cold exposure increases ET-1 production and upregulat...

The hippocampal slice is a popular model system in which to study the cellular properties of long-term potentiation (LTP). Synaptogenesis induced by exposure to ice-cold artificial cerebrospinal fluid (ACSF), however, raises the concern that morphological correlates of LTP might be obscured, especially in mature slices. Here we demonstrate that preparation of mature hippocampal slices at room t...
