Hypothermia and localized cold injuries are largely preventable with proper preparation for activities in cold environments. Proficient field management is crucial to the final outcome in terms of function and viability because proper care is vital to preventing exacerbation of the initial exposure and injury. Rapid rewarming is optimal when further cold exposure can be avoided reliably. Repeti...

There is substantial diversity in Achillea biebersteinii plants in Iran. It has considerable different biological activities including antibacterial, antifungal, antioxidant, insecticidal, herbicidal and wound healing. Research improvement for medicinal plants depends on the available genetic diversity. The assessment of genetic variability could increase the information for breeding programs. ...

Salicylic acid (SA) plays an important role in the regulation of plant ripening and responses to abiotic stresses. In this study, the protective effect of SA on cold stress-caused oxidative damage in grape (Vitis vinifera L.) bunches was investigated during cold storage.  Grape bunches treated with 2 mM SA and  stored at 0°C with 85-90% RH for 30 days. Samples were selected from each treatment ...

For many years, non-freezing cold shock injury has been associated with damage to the cell membrane. In this study, we enhanced membrane cholesterol levels of Drosophila melanogaster by raising larvae on a cholesterol-augmented diet. Diet augmentation significantly increased the amount of cholesterol in the cell membranes of the adult flies (1.57+/-0.17 nmol per mg vs. 0.93+/-0.11 nmol per mg)....

This paper presents an unusual case of frostbite injury to the breast area caused by faulty cryotherapy application. Cryotherapy, commonly used by patients and health professionals, relieves pain and edema after trauma and sports injuries. However, applying cold therapy is not common for surgical procedures involving soft tissue. The frostbite injury to the breast presented here occurred due to...

ABA, a phytohormone, regulates many agronomically important aspects of plant growth and development, including seed maturation, dormancy and stress tolerance (Finkelstein et al. 2002). During vegetative growth, endogenous ABA levels increase upon conditions of water stress, and ABA acts as an essential mediator in triggering the plant response to these adverse environmental stresses (Finkelstei...

Montane and subalpine grasslands are prominent, but poorly understood, features of the Rocky Mountains. These communities frequently occur below reversed tree lines on valley floors, where nightly cold air accumulation is spatially coupled with fine soil texture. We used field experiments to assess the roles of minimum temperature, soil texture, grass competition, and ungulate browsing on the g...
