Dormant Arabidopsis (Arabidopsis thaliana) seeds do not germinate easily at temperatures higher than 10–15 °C. Using mutants affected in ethylene signaling (etr1, ein2 and ein4) and in the N-end-rule pathway of the proteolysis (prt6 and ate1-ate2) we have investigated the effects of cold and ethylene on dormancy alleviation. Ethylene (10–100 ppm) a...
Dans nos régions tempérées, de la chute des feuilles à l’automne à l’éclosion des bourgeons au printemps, la nature semble endormie, comme engourdie par le froid. Pourtant, il se passe de nombreuses choses à l’intérieur d’un arbre en hiver. Des mécanismes physiologiques continuent à s'activer, d’autres à s’inhiber et de nouveaux s’enclenchent. Ces ...

Acetaminophen use and over-dosing increases in CFS, primarily due to increased use of OTC combinations treating upper respiratory cold/flu symptoms. Pharmacists should warn users to follow labeled dosing directions, especially during CFS.

Workers in the Arctic open-pit mines are exposed to harsh weather conditions. Employers are required to provide protective clothing for workers. This can be the outer layer, but sometimes also inner or middle layers are provided. This study aimed to determine how Arctic open-pit miners protect themselves against cold and the sufficiency, and the se...

Abiotic stress tolerance was identified in multiple B. oleracea crop types, with some lines exhibiting resistance to multiple stresses. For each stress, no one crop type appeared significantly more or less tolerant than others. The results are promising for the development of more environmentally robust lines of different B. oleracea crops by ident...

Thermal manipulation during embryogenesis was previously reported to decrease the occurrence of ascites and to potentially improve cold tolerance of broilers. The objective of our study was to explore the effects of the interaction of cold incubation temperatures and cool ambient temperatures until 21 d of age on performance and body temperature. R...

Insect overwintering is one of the most astonishing phases of the insect life cycle. Despite vast amounts of knowledge available about the physiological mechanisms of this phenomenon, the impact of stress factors on insect immune system functioning during the winter is still unknown. The aim of this study is to analyze how low temperatures influenc...

Aside from a small population of primary afferent neurons for sensing cold, which generate sensations of innocuous and noxious cold, it is generally believed that cold temperatures suppress the excitability of primary afferent neurons not responsible for cold sensing. These not-for-cold-sensing neurons include the majority of non-nociceptive and no...
Résumé Cet article s’intéresse à la perception que les Inuit ont du climat et des différentes saisons en s’appuyant sur plusieurs sources (dictionnaires unilingues, littérature autochtone, photos de famille). Il montre l’importance du froid dans l’identité inuit alors que le réchauffement climatique se manifeste tout particulièrement dans les terri...
