osmotic shock การใช้

• Osmotic shock is sometimes used to release cellular components, such as oil.
• Methods based on vortex mixing and osmotic shock cause death of many spores.
• Mechanisms for homogenization include grinding, mincing, chopping, pressure changes, osmotic shock, freeze-thawing, and ultra-sound.
• Mutations that affect upregulated under stressful conditions such as caloric restriction, heat shock, and osmotic shock.
• Calcium also acts as one of the primary regulators of osmotic stress ( Osmotic shock ).
• Osmotic shock is a sudden reduction in osmotic pressure, this can cause cells in a solution to rupture.
• Many organisms will come through this process unharmed as long as the osmotic shock does not last too long.
• These processes occur in response to stresses such as near-UV radiation, acid, temperature or osmotic shock, oxidative stress, and nutrient deprivation.
• Large numbers of starch granules can be emitted when the grain comes into contact with water through a process called osmotic shock.
• MscM is activated first at really low pressures followed by MscS, and finally MsCL being the last chance of survival during osmotic shock.
• Additionally, osmotic shock resulting from water potential changes can impact enzyme activities as microbes redirect energy from enzyme production to synthesizing osmolytes to maintain cellular structures.
• However, the first direct genetic evidence of dehydrin playing a role in cellular protection during osmotic shock was not observed until 2005, in the moss, " Physcomitrella patens ".
• Although single-celled organisms are more vulnerable to osmotic shock, since they are directly exposed to their environment, cells in large animals such as mammals still suffer these stresses under some conditions.
• The first, and simplest, is osmotic shock, this is achieved by submerging the sample in fresh water ( clearly this will only work for marine samples ) for a few seconds.
• Similar to the SAPK / JNK pathway, p38 MAP kinase is activated by a variety of cellular stresses including osmotic shock, inflammatory cytokines, lipopolysaccharides ( LPS ), Ultraviolet light, and growth factors.
• Although their signaling appears very complex, the MPK3, MPK4 and MPK6 kinases of " Arabidopsis thaliana " are key mediators of responses to osmotic shock, oxidative stress, response to cold and involved in anti-pathogen responses.
• All organisms have mechanisms to respond to osmotic shock, with sensors and signal transduction networks providing information to the cell about the osmolarity of its surroundings; these signals activate responses to deal with extreme conditions.
• In cases where one is replacing a tap water-based salt mix with a reverse osmosis-based salt mix, the replacement water should be added slowly over the course of several hours to avoid sending the aquarium inhabitants into osmotic shock.
• Energy drinks also contain taurine which helps to do a lot of things but in energy drinks it's particularly helpful due to it's effects of countering osmotic shock ( good if you're an athlete ) and it's role of being a surfactant of the cholic acid conjugate.
• I " think " the effect of missing the vein is simple osmotic shock from that very high concentration of solute in the sugar solution, which is required in order that a reasonable volume have an effect on the entire blood supply . talk ) 14 : 04, 3 March 2015 ( UTC)
