background previous studies showed that shallomin, the active antimicrobial constituent of persian shallot, has a wide range of antibacterial and antifungal properties. objectives the objective of this randomized clinical trial was to evaluate the effectiveness of topical shallomin alcoholic solution in treatment of cold sore. patients and methods a total of 60 volunteers who met the inclusion ...

increasing of wood demand is currently one of the most important problems in our society. different clones of populus nigra from salicacea as a native fast-growing species have a good potential for planting in wide scale. but because of the ecological differences in the field, especially. temperature alterations, segregation of the cold resistant clones in relation to in seedling stage establis...

A fundamental property of many organisms is an ability to sense, evaluate, and respond to environmental signals. In some situations, generation of an appropriate response requires long-term information storage. A classic example is vernalization, where plants quantitatively sense long-term cold and epigenetically store this cold-exposure information to regulate flowering time. In Arabidopsis th...

There is considerable interest in the use of psychrotrophic bacteria for food biopreservation and in the understanding of cold adaptation mechanisms. The psychrotrophic biopreservative Lactococcus piscium strain CNCM I-4031 was studied for its growth behavior and proteomic responses after cold shock and during cold acclimation. Growth kinetics highlighted the absence of growth latency after col...

BACKGROUND Local freezing cold injuries are common in the north and sequelae to cold injury can persist many years. Quantitative sensory testing (QST) can be used to assess neurosensory symptoms but has previously not been used on cold injury patients. OBJECTIVE To evaluate neurosensory sequelae after local freezing cold injury by thermal and vibrotactile perception thresholds and by symptom ...

During cellular adaptation to low temperature, Escherichia coli transiently synthesizes the major cold-shock protein CspA. It was found that adaptation to cold shock is blocked when the 143-base sequence of the 5' untranslated region (5' UTR) of the cspA mRNA is overproduced. The overproduction of this UTR at 15 degrees C caused the synthesis of not only CspA but also other cold-shock proteins ...

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...

Cold tolerance in plants is an ecologically important trait that has been under intensive study for basic and applied reasons. Determining the fitness benefits and costs of cold tolerance has previously been difficult because cold tolerance is normally an induced trait that is not expressed in warm environments. The recent creation of transgenic plants constitutively expressing cold tolerance g...

Storage and distribution are the weakest links in the food management. Their effective control is important for their commercial viability, since they often deviate from specifications. FRISBEE (http://frisbee-project.eu) is a Food Refrigeration Innovation for Cold Chain research IP European project. Within FRISBEE a web-based platform (hosted in the link http://www.frisbeeproject.eu/coldchaind...

Zaradic of the US Environmental Leadership Programme, compared records of visits to dozens of national parks, state parks and other public land across the US, Japan and Spain. They also analysed US licence applications to hunt deer, fish and shoot wildfowl, as well as surveys on the popularity of outdoor pursuits such as camping and hiking. They found that the popularity of almost all activitie...
