“…1 and 2. The dynamics of alterations in the pools of majority of nonessential FA in the P. glehni brain in three episodes of seasonal temperature decrease-in summer, in the beginning of autumn, and in the beginning of winter-was opposite to the results obtained earlier for muscles, as well as to the great degree-for blood [5]. Two non-protein amino acids, PEA and phosphoserine, were found in brain, but were absent in muscles and blood un-der any temperature conditions ( Table 1, Fig.…”

“…For example, brain taurine level decreased during the entire period of cold shock impact, although in blood and muscles after temporal decrease it rose again. Besides, simultaneously with a decrease in taurine pool we recorded an intensive rise in the level of unidentified amino acid, never revealed in our previous works either in fish blood or muscle or in fluids of fresh water mollusc and amphipod [5].…”

“…1). Earlier, the taurine content in the P. glehni muscles during winter period, in contrast, was shown to rise several times in comparison with that in summer [5]. Pools of glycine, alanine, GABA, and histidine decreased considerably by the beginning of autumn (especially the histidine pool), but increased by the winter period.…”

“…The sleepers P. glehni were caught in the Lake Tulchino (the Ob' River area, 54°50' n.a., 37°42' e.l.) at the end of the third decade of June, at the first decade of September and December of 2010 and 2011. The fishing for determination of FA pools in the P. glehni brain was performed at the same time as the fishing for analogous experiments performed earlier on muscles and blood [5]. The individuals with the mean weight of 28.3 ± 2.5 g were selected from all obtained materials.…”

“…At present, there have been intensively investigated different types of development of stress response to low temperatures, such KARANOVA The responses of FA to low-temperature impacts in brain of ectothermic vertebrates are virtually not studied in spite of that brain of these animals is a quite interesting object for such investigation, since it combines homology and specificity of biochemical mechanisms of adaptation of ectotherms and homoiotherms to stress. The author's previous work has shown that action of acute cold shock (0°C) induces in brain of the euritherm fish Perccottus glehni the responses of some FA opposite to their responses in blood and muscles [5]. For example, brain taurine level decreased during the entire period of cold shock impact, although in blood and muscles after temporal decrease it rose again.…”

The present work studied effect of a seasonal decrease of environmental temperature and cold shock on pools of free amino acids (FA) in brain of the euritherm lake fish P. glehni. For the first time, non-protein amino acid, phosphoethanolamine (PEA), revealed in the great amounts under conditions of near-zero temperatures was found in brain of ectothermic animals. An intensive rise of the PEA pool from 0.3% during the summer period to 33.6% at winter was shown to occur in the brain of P. glehni as a result of a seasonal temperature decrease. In contrast, the level of taurine showing the greatest pool in comparison with other FA (29.0% of the total pool) in summer decreases to 8.9% in the beginning of winter period. Similar negative correlation between the taurine and PEA content was found under effect of acute cold shock (1°C): the taurine level decreased for 4 days from 32.2 to 14.5% of the total pool, whereas the PEA level sharply increased (from 2.1 to 15.3%). Both types of the low-temperature actions have revealed, besides PEA, an intensive rise in the pool of serine and accumulation of phosphoserine. The role of PEA in biochemical evolution and adaptation of the brain to low temperatures is discussed. It is supposed that accumulation of PEA, phosphoserine, and serine is associated with changes in the status of membrane phospholipids at low temperatures.

Temperature is critical in regulating virtually all biological functions in fish. Low temperature stress (cold shock/stress) is an often-overlooked challenge that many fish face as a result of both natural events and anthropogenic activities. In this study, we present an updated review of the cold shock literature based on a comprehensive literature search, following an initial review on the subject by M.R. Donaldson and colleagues, published in a 2008 volume of this journal. We focus on how knowledge on cold shock and fish has evolved over the past decade, describing advances in the understanding of the generalized stress response in fish under cold stress, what metrics may be used to quantify cold stress and what knowledge gaps remain to be addressed in future research. We also describe the relevance of cold shock as it pertains to environmental managers, policymakers and industry professionals, including practical applications of cold shock. Although substantial progress has been made in addressing some of the knowledge gaps identified a decade ago, other topics (e.g., population-level effects and interactions between primary, secondary and tertiary stress responses) have received little or no attention despite their significance to fish biology and thermal stress. Approaches using combinations of primary, secondary and tertiary stress responses are crucial as a research priority to better understand the mechanisms underlying cold shock responses, from short-term physiological changes to individual-and population-level effects, thereby providing researchers with better means of quantifying cold shock in laboratory and field settings.

Role of the tissue free amino acids in adaptation of medicinal leeches Hirudo medicinalis L., 1758 to extreme climatic conditions

The first comparison of the spectra of free amino acids in tissues of the medicinal leeches H. medicinalis from different climatic and geographical Eurasian areas has been performed. Adaptation of H. medicinalis to extreme climatic conditions occurs via intensification of the amino acid metabolism resulting from a significant increase in the content of essential amino acids. Accumulation of arginine, histidine, and lysine (3.6-, 3.9-, and 2.0-fold increases, respectively) has proved to play a special protective role in adaptation of H. medicinalis to the low positive temperatures.
