The molecular basis of short term cold resistance (indexed as chill-coma recovery time) has been mostly addressed in D. melanogaster, where candidate genes (Dca (also known as smp-30) and Frost (Fst)) have been identified. Nevertheless, in Drosophila, the ability to tolerate short term exposure to low temperatures evolved several times independently. Therefore, it is unclear whether variation i...

PURPOSE This study was conducted to examine public level of knowledge and attitudes regarding antibiotic use and potential drug resistance. METHODS A cross-sectional face-to-face survey of 1,177 residents aged 18 or over was conducted in Korea. A quota sampling method was used. RESULTS Most respondents (70%) did not know that antibiotics are ineffective in treating coughs and colds. Two-thi...

Laboratory research on hypertension often is performed with cold stress to elicit vasoconstriction and increases in blood pressure. Several studies have shown that cardiovascular responses to the cold pressor test predict the development of hypertension. We extended this research by comparing cardiovascular responses to a traditional forehead cold pressor test and a naturalistic whole-body cold...

Larvae of the Antarctic midge, Belgica antarctica (Diptera: Chironomidae), are frequently exposed to dehydrating conditions on the Antarctic Peninsula. In this study, we examined how rates and levels of dehydration alter heat and cold tolerance and how these relate to levels of trehalose within the insect. When dehydrated, larvae tolerated cold and heat stress more effectively, although resista...
