«An acute stress hormone response is likely to enhance adaptive immunity and wound healing, whereas the sluggish and prolonged elevation» of stress hormones «is likely to impair immune function.»

This response may be an adaptive strategy to moderate stress to ensure survival, but the accumulation of damaged Symbiodinium, which causes subsequent coral deterioration, may occur when this response can not cope with the magnitude or duration of environmental stress, and this might be a possible mechanism underlying coral bleaching during prolonged moderate thermal stress.

In particular, the cAMP signaling cascade directs adaptive cellular responses to a variety of stress stimuli via a combination of acute affects arising from GS - protein coupled receptor (GPCR)- mediated activation of PKA and long - term affects resulting from transcriptional reprogramming directed by CREB and the CREB Regulated Transcription Coactivators (CTRCs).

The published paper concluded that» «molecular alterations detected in the ocular hypertensive human retina as opposed to previously detected alterations in human donor retinas with clinically manifest glaucoma suggest that proteome alterations determine the individual threshold to tolerate the ocular hypertension - induced tissue stress or convert to glaucomatous neurodegeneration when intrinsic adaptive / protective responses are overwhelmed.»

A sustained modest weight - loss of five to 10 % body - weight is associated with improvements in various indices of cardiometabolic health including but not limited to insulin sensitivity, vascular function, blood pressure and lipid levels.3 These beneficial effects of weight - loss can be partially explained by accompanying reductions in adipose tissue mass and dysfunction.5 There is however, some evidence to suggest that energy restriction (ER) alone can confer metabolic changes which are independent to those of weight - loss, by facilitating an acute negative energy balance 6 - 9 and / or by activating adaptive stress response pathways.10

«Fasting is a challenge to your brain, and we think that your brain reacts by activating adaptive stress responses that help it cope with disease.»

The main hypothesis includes a stress preconditioning response mechanism, in which it is believed that periods of nutrient deprivation displays a beneficial mild stress that results in molecular adaptive changes in various tissues, which increases the organism's resistance to bigger stressors such as excitotoxic and oxidative injury, including ischemia (33,71).

There's no way I could do justice to the complex mixture of phytochemicals in those plants, but various glucosinolates (really, their isothiocyanate products) and quercetin from kale; the anthocyanins from blueberries; mangiferin from mangos; and gallic acid, ellagic acid, quercetin, kaempferol from amla all induce the «adaptive stress response» as described above.

Rather, some of the most effective phytochemicals appear to work via the PRO-oxidant reaction of their quinone metabolites with thiols on the sensor protein Keap1, releasing the transcription regulator Nrf2 into the nucleus to initiate an adaptive stress response.

Within minutes of a stressful event (and possibly lasting for several hours), a much more elaborate interaction between the nervous and endo - crine systems and other forms of internal communication occurs, resulting in a very complex adaptive response to deal with the stress.

Based on human and animal research, it appears a variety of nutritional and botanical substances — such as adaptogenic herbs, specific vitamins including ascorbic acid, vitamins B1 and B6, the coenzyme forms of vitamin B5 (pantethine) and B12 (methylcobalamin), the amino acid tyrosine, and other nutrients such as lipoic acid, phosphatidylserine, and plant sterol / sterolin combinations — may allow individuals to sustain an adaptive response and minimize some of the systemic effects of stress.

The key role of caregiver nurturance in hippocampal development and its relationship to adaptive stress responses has been well established in animal studies.

In the context of low adversity, children who have a high reactivity to stress are actually more social and successful academically than their peers who have a low reactivity to stress.21 However, in the context of high adversity, children who have high reactivity to stress fair worse than their peers who have low reactivity to stress.21 Hence, the consequences of high stress reactivity are contextual, with high reactivity promoting adaptive responses in the context of low adversity, but maladaptive responses in the context of high adversity.

One final example is the prefrontal cortex, which is thought to play an important role in regulating behavior by suppressing impulses and emotions arising from the amygdala and other parts of the limbic system.50 — 52 In animal studies, exposure to chronic stress or glucocorticoids alters the synaptic connectivity within the prefrontal cortex, 52,53 and this may limit the ability of the prefrontal cortex to (1) suppress the impulsivity and aggression of the limbic system, and (2) execute adaptive responses (rather than maladaptive responses) to stress.54 — 56 Stress - induced changes in brain structure parallel the well - described impact of significant childhood adversity on a variety of brain functions, including the modulation of physiologic responses (hyper - responsive or chronically active stress response), learning (impaired memory), and the regulation of behavior (the ability to execute adaptive vs maladaptive responses to stress).3,stress or glucocorticoids alters the synaptic connectivity within the prefrontal cortex, 52,53 and this may limit the ability of the prefrontal cortex to (1) suppress the impulsivity and aggression of the limbic system, and (2) execute adaptive responses (rather than maladaptive responses) to stress.54 — 56 Stress - induced changes in brain structure parallel the well - described impact of significant childhood adversity on a variety of brain functions, including the modulation of physiologic responses (hyper - responsive or chronically active stress response), learning (impaired memory), and the regulation of behavior (the ability to execute adaptive vs maladaptive responses to stress).3,stress.54 — 56 Stress - induced changes in brain structure parallel the well - described impact of significant childhood adversity on a variety of brain functions, including the modulation of physiologic responses (hyper - responsive or chronically active stress response), learning (impaired memory), and the regulation of behavior (the ability to execute adaptive vs maladaptive responses to stress).3,Stress - induced changes in brain structure parallel the well - described impact of significant childhood adversity on a variety of brain functions, including the modulation of physiologic responses (hyper - responsive or chronically active stress response), learning (impaired memory), and the regulation of behavior (the ability to execute adaptive vs maladaptive responses to stress).3,stress response), learning (impaired memory), and the regulation of behavior (the ability to execute adaptive vs maladaptive responses to stress).3,stress).3, 39,57
