Sphingolipids, glycosylphosphatidylinositol (GPI)-anchored proteins, and certain signaling molecules segregate from bulk membrane lipids into lateral domains termed lipid rafts, which are often isolated based on their insolubility in cold nonionic detergents. During immunohistological studies of gangliosides, major sphingolipids of the brain, we found that cold Triton X-100 solubility is bidire...

Klotho is a recently identified antiaging gene. Brain endothelin-1 (ET1) is important in the regulation of blood pressure (BP). We hypothesized that silence of brain klotho potentiates cold-induced elevation of BP via the endothelin pathway. To silence brain klotho, we constructed adeno-associated virus (AAV) carrying rat klotho small interference hairpin RNA (KL-shRNA). AAV carrying ET1-shRNA ...

Nerve extracts containing tubulin labeled by axonal transport were analyzed by electrophoresis and differential extraction. We found that a substantial fraction of the tubulin in the axons of the retinal ganglion cell of guinea pigs is not solubilized by conventional methods for preparation of microtubules from whole brain. In two-dimensional polyacrylamide gel electrophoresis this cold-insolub...

According to the Traditional Iranian Medicine (TIM), each body organ owns its specific temperament (1). Temperament is composed of four qualities (elements) of " warmth " , " coldness " , " wetness " and " dryness " (2). " Wetness " and " dryness " are considered as a spectrum of " tissue moistures " and " warmth " and " coldness " may be regarded as the basic metabolism of the organ. Iranian S...

BACKGROUND Episodes of paroxysmal atrial fibrillation may be precipitated by the rapid ingestion of ice-cold foods and beverages. This condition has received little research attention, and its true prevalence is poorly described. Treating physicians may not identify cold ingestion as a causal factor of paroxysmal atrial fibrillation, thus compromising both history taking and patient education. ...

Thermosensation is an indispensable sensory modality. Here, we study temperature coding in Drosophila, and show that temperature is represented by a spatial map of activity in the brain. First, we identify TRP channels that function in the fly antenna to mediate the detection of cold stimuli. Next, we identify the hot-sensing neurons and show that hot and cold antennal receptors project onto di...

Exposure to fluctuating temperatures accelerates the mitochondrial respiration and increases the formation of mitochondrial reactive oxygen species (ROS) in ectothermic vertebrates including fish. To date, little is known on potential oxidative damage and on protective antioxidative defense mechanisms in the brain of fish under cold shock. In this study, the concentration of cellular protein ca...

126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...

Recent evidence exists that enoxaparin can reduce brain injury because of its anticoagulant activity. To investigate the potential therapeutic effect of enoxaparin on cold-induced traumatic brain injury, at 20 minutes after modeling, male BALB/c mouse models of cold-induced traumatic brain injury were intraperitoneally administered 3 and 10 mg/kg enoxaparin or isotonic saline solution. Twenty-f...
