Effect of trauma on plasma glucagon and insulin concentrations in sheep. (1/9717)

Portal plasma glucagon and insulin concentrations were measured before and after acute trauma (liver biosy). The trauma was sufficient to increase glucagon concentrations and depress insulin concentrations. These changes were associated with a marked hyperglycemia. Infusion of glucagon was insufficient to prevent stress inhibition of insulin secretion. The stimulation of glucagon secretion and inhibition of insulin secretion were of about one hour duration. These findings indicate that glucagon and insulin in conjunction with the nervous system may play an important role in the development of stress related hyperglycemia.  (+info)

Nitric oxide stimulates the stress-activated protein kinase p38 in rat renal mesangial cells. (2/9717)

Nitric oxide (NO) has gained increased attention as a diffusible universal messenger that plays a crucial role in the pathogenesis of inflammatory and autoimmune diseases. Recently, we reported that exogenous NO is able to activate the stress-activated protein kinase (SAPK) cascade in mesangial cells. Here, we demonstrate that exposure of glomerular mesangial cells to compounds releasing NO, including spermine-NO and (Z)-1- (N-methyl-N-[6-(N-methylammoniohexyl)amino]diazen)-1-ium-1,2-diolate (MAHMA-NO), results in an activation of the stress-activated p38-mitogen-activated protein kinase (p38-MAPK) cascade as measured by the phosphorylation of the activator of transcription factor-2 (ATF2) in an immunocomplex kinase assay. Activation of the p38-MAPK cascade by a short stimulation (10 min) with the NO donor MAHMA-NO causes a large increase in ATF2 phosphorylation that is several times greater than that observed after stimulation with interleukin-1beta, a well-known activator of the p38-MAPK pathway. Time course studies reveal that MAHMA-NO causes rapid and maximal activation of p38-MAPK after 10 min of stimulation and that activation declines to basal levels within 60 min. The longer-lived NO donor spermine-NO causes a comparable rapid activation of the p38-MAPK pathway; however, the increased activation state of p38-MAPK was maintained for several hours before control values were reattained after 24 h of stimulation. Furthermore, the NO donors also activated the classical extracellular signal-regulated kinase (ERK) p44-MAPK cascade as shown by phosphorylation of the specific substrate cytosolic phospholipase A2 in an immunocomplex kinase reaction. Both MAHMA-NO and spermine-NO cause a rapid activation of p44-MAPK after 10 min of stimulation. Interestingly, there is a second delayed peak of p44-MAPK activation after 4-24 h of stimulation with NO donors. These results suggest that there is a differential activation pattern for stress-activated and mitogen-activated protein kinases by NO and that the integration of these signals may lead to specific cell responses.  (+info)

Effects of soybean oil emulsion and eicosapentaenoic acid on stress response and immune function after a severely stressful operation. (3/9717)

OBJECTIVE: To investigate the effects of soybean oil emulsion and oral or enteral administration of eicosapentaenoic acid (EPA) on stress response, cytokine production, protein metabolism, and immune function after surgery for esophageal cancer. SUMMARY BACKGROUND DATA: It has been reported that safflower oil, rich in n-6 polyunsaturated fatty acid (n-6 PUFA), affects the survival rate of septic animals and decreases the immune function. It has also been reported that the administration of fish oil, in contrast, reduces these stress responses and stress-induced immunosuppression. In humans, the effects of soybean oil emulsion and the administration of EPA on stress response and immune function after surgery have not been established. METHODS: Patients who underwent esophagectomy with thoracotomy were divided into three groups. Seven patients were fed by total parenteral nutrition (TPN) with soybean oil emulsion, which accounted for 20% of total calories. Seven patients were given oral or enteral administration of 1.8 g/day EPA, in addition to TPN with soybean oil emulsion. Nine patients served as the control group; these patients received fat-free TPN. Serum interleukin-6 (IL-6), C-reactive protein, concanavalin A (con A)- or phytohemagglutinin (PHA)-stimulated lymphocyte proliferation, natural killer cell activity, and stress hormones were measured. RESULTS: The postoperative level of serum IL-6 was significantly higher in the group receiving soybean oil emulsion than in the fat-free group. Oral or enteral supplementation of EPA with soybean oil emulsion significantly reduced the level of serum IL-6 compared with the patients receiving soybean oil emulsion. Con A- or PHA-stimulated lymphocyte proliferation decreased significantly on postoperative day 7 in all groups of patients. The supplementation of EPA with soybean oil emulsion significantly improved the lymphocyte proliferation and natural killer cell activity on postoperative day 21 compared with the group receiving soybean oil emulsion. CONCLUSIONS: Soybean oil emulsion amplifies, and the supplementation of EPA reduces, the stress response and stress-induced immunosuppression.  (+info)

Mechanical stimulation of starfish sperm flagella. (4/9717)

1. The responses of starfish sperm flagella to mechanical stimulation with a microneedle were analysed. Flagellar movement was recorded by high-speed microcinematography and by stroboscopic observation. 2. The amplitude of the bending wave of a flagellum was restricted over its entire length when the microneedle was brought near to the flagellum at its proximal region. Beyond the restricted part, the amplitude of the wave, and the bend angle, became smaller than those of a normally beating flagellum, while the curvature was practically unchanged. 3. When the tip of the microneedle was in contact with the flagellum, propagation of the bending wave beyond the microneedle was inhibited. The part of the flagellum between the base and the microneedle continued beating in some cases and stopped beating in other cases. The flagellum beyond the arrested part stopped beating and remained straight. When the microneedle was removed, the bending wave which existed in the part of the flagellum proximal to the microneedle, or the wave which was passively formed de novo at the time of the removal of the microneedle, propagated over the arrested part towards the tip. 4. A flagellum amputated by a microneedle in a medium containing ATP continued beating with a small amplitude, small curvature, small bend angle and low frequency. When the amputated flagellum was passively bent by a microneedle at the region near the point of amputation, this bend propagated towards the tip with a constant bend angle. 5. The beating frequency of the flagellum could be modulated by the application of a rhythmic external force generated by vibrating a microneedle near the flagellum. The beating was completely synchronized with vibration of the microneedle in the frequency range from 23 Hz to 43 Hz.  (+info)

Influence of a new antiulcer agent, ammonium 7-oxobicyclo (2, 2, 1) hept-5-ene-3-carbamoyl-2-carboxylate (KF-392) on gastric lesions and gastric mucosal barrier in rats. (5/9717)

Antiulcer effects of KF-392 were studied in several experimental gastric ulcer models in rats. It was found that KF-392 given orally at 1.0 to 5.0 mg/kg had a marked suppression on the developments of Shay ulcer as well as the aspirin-, stress-, and reserpine-induced gastric lesions. The influence of KF-392 on gastric mucosal barrier was also studied. A back diffusion of H+ into the gastric mucosa and a fall of transmucosal potential difference were induced with KF-392 given orally at the above mentioned doses. KF-392 given s.c. at 5.0 mg/kg showed no inhibition of Shay ulcer and no induction of back diffusion of H+ into the gastric mucosa.  (+info)

The Ca2+ channel blockade changes the behavioral and biochemical effects of immobilization stress. (6/9717)

We investigated how the effects of chronic immobilization stress in rats are modified by Ca2+ channel blockade preceding restraint sessions. The application of nifedipine (5 mg/kg) shortly before each of seven daily 2 h restraint sessions prevented the development of sensitized response to amphetamine as well as the stress-induced elevation of the densities of L-type Ca2+ channel in the hippocampus and significantly reduced the elevation of the densities of [3H]nitrendipine binding sites in the cortex and D1 dopamine receptors in the limbic forebrain. Neither stress, nor nifedipine affected the density of alpha 1-adrenoceptors and D1 receptors in the cerebral cortex nor D2 dopamine receptors in the striatum. A single restraint session caused an elevation of blood corticosterone level that remained unaffected by nifedipine pretreatment, but the reduction of this response during the eighth session was significantly less expressed in nifedipine-treated rats. We conclude that L-type calcium channel blockade prevents development of several stress-induced adaptive responses.  (+info)

The effects of low-copper diets with or without supplemental molybdenum on specific immune responses of stressed cattle. (7/9717)

Angus bull calves (n = 42; 7 mo of age; 254 kg initial BW) were used to investigate the effects of dietary Cu and Mo on immune function of stressed cattle. Randomly selected calves (n = 22) were injected with 90 mg of Cu as Cu glycinate 28 d before weaning and castrated at weaning. These calves received 7.5 and 5 mg of supplemental Cu/kg of DM during a 41-d receiving phase and a 196-d growing phase, respectively. The remainder of the steers received no supplemental Cu during the experiment. Copper-supplemented steers had adequate Cu status at weaning, whereas unsupplemented calves were marginally Cu-deficient. Cell-mediated response to intradermal injection of phytohemagglutinin was not affected by dietary treatment during the receiving phase. During the growing phase, half of the steers in each Cu treatment were given 5 mg of supplemental Mo/kg of DM. Copper supplementation increased (P<.05) humoral response to ovalbumin injected on d 133 of the growing phase. On d 168 of the growing phase, calves receiving only supplemental Mo were severely Cu-deficient based on plasma and liver Cu concentrations. The other treatment groups had adequate Cu status. Before feeding on d 168 of the growing phase, half of the steers were loaded onto trailers and transported 2.5 h, and they remained on the trailers an additional 9.5 h. Humoral response to porcine erythrocytes (PRBC) and delayed-type hypersensitivity (DTH) to dinitrochlorobenzene was tested at the end of the stress period. There was a Cu x stress interaction for humoral response to PRBC, with Cu decreasing antibody titers in unstressed calves and increasing titers in stressed steers. Stressed steers had lower (P = .03) ADG during the 28 d following stress. The results of this study indicate that Cu deficiency and 5 mg of supplemental Mo/kg of DM do not dramatically alter the specific immunity of stressed cattle.  (+info)

Individual and organizational predictors of depression in general practitioners. (8/9717)

BACKGROUND: High levels of stress and depression are seen in both general practitioners (GPs) and hospital doctors, and this has implications for patient care. It is therefore important to discover the individual and organizational causes of elevated symptoms so they can be tackled. AIM: To discover the relative importance of individual characteristics measured 10 years earlier compared with current organizational stressors in predicting depression in GPs. METHOD: Longitudinal questionnaire study, using data from those of the original cohort of 318 medical students who are now GPs (n = 131), considering perceptions of current stressors and comparing through regression analyses the relative strength of early personality and mood with current organizational factors of sleep, hours worked, and practice size in predicting current depression levels. RESULTS: There were 22 (17%) stressors scoring above threshold for depression. Relationships with senior doctors and patients are the main reported stressors, followed by making mistakes and conflict of career with personal life. The predictors of symptom levels varied for men and women. In men, depression and self-criticism as students, and current sleep levels; and in women, sibling rivalry and current alcohol use, were the main predictors: in men, 27% of the variance was accounted for by early dispositional factors alone compared with 14% in women. A model is suggested linking sleep loss with workplace stressors, self-critical cognitions, and depression. CONCLUSION: Interventions can be made throughout training, targeting self-criticism and recognizing early depression, while later addressing the organizational stressors, particularly work relationships and sleep patterns.  (+info)

In new research, the scientists have learned that the mechanical properties of the bungee-like fimbriae also play a key role in the tenacity of E. coli clinging to mucousal surfaces. The tiny fiber-like protrusions are made up of interlocking protein segments in a tightly coiled helix shape, like a seven-nanometer-wide Slinky toy. The researchers found that under force, the fimbriae stretch to many times their original length as the protein segments uncoil one by one. If the force on them drops, the fimbriae coils are compressed, keeping tension on the bond between the bacterium and the mucous membrane ...

Environmental stresses induce a program of coordinate gene expression designed to remedy the underlying cellular disturbance or, alternatively, induce apoptosis. Facilitating this stress response are transcriptional regulators, such as activating transcription factor 3 (ATF3), a member of the ATF/CREB subfamily of the basic-region leucine zipper (bZIP) family (26). ATF3 levels are dramatically induced in response to a variety of stress conditions in many different tissues (26, 27). For example, ATF3 is increased in liver exposed to acetaminophen, cycloheximide, carbon tetrachloride, or alcohol, in heart or pancreas subjected to ischemia coupled with reperfusion, in brain by seizure, in pancreas following streptozotocin treatment, and in cultured cells following exposure to a variety of stress treatments, including UV light and ionizing radiation, proteasome inhibitors, and homocysteine. ATF3 mRNA usually increases within 2 h of stress exposure, and ATF3 protein can function as a homodimer or as ...
One function of glucocorticoids is to restore homeostasis after an acute stress response by providing negative feedback to stress circuits in the brain. Loss of this negative feedback leads to elevated physiological stress and may contribute to depression, anxiety, and post-traumatic stress disorder. We investigated the early, developmental effects of glucocorticoid signaling deficits on stress physiology and related behaviors using a mutant zebrafish, grs357, with non-functional glucocorticoid receptors (GRs). These mutants are morphologically inconspicuous and adult-viable. A previous study of adult grs357 mutants showed loss of glucocorticoid-mediated negative feedback and elevated physiological and behavioral stress markers. Already at 5 days post-fertilization, mutant larvae had elevated whole body cortisol, increased expression of pro-opiomelanocortin (POMC), the precursor of adrenocorticotropic hormone (ACTH), and failed to show normal suppression of stress markers after dexamethasone ...

Each cell produces/synthesizes proteins. This process is vital for the cells ability to develop and function properly. In the course of the protein metabolism protein molecules break down into smaller fractions = peptides. These peptides are in turn used by the cells to form new proteins. A sufficient amount of these peptides are required for optimal protein synthesis, and thus cell function. If the cells function well, then the organs and body systems work well. In young body protein synthesis works very well and it is sufficiently formed on peptides. With increasing age, unfortunately, the intensity of protein synthesis in cells decreases rapidly. That is also the reason why many body systems in the elderly may not function properly. Scientists have also discovered that even a young organism under the influence of extreme adverse conditions, such as permanent psycho emotional stress, increased physical stress, harmful environmental factors, poor diet etc. decreases the intensity of protein ...

In search of localised membrane protein assembly centres in bacteria. PspA (Phage-Shock Protein A) is a widespread bacterial protein known to be important for preserving membrane integrity under environmental stress conditions. The related Vipp1 protein is found in cyanobacteria (and plant chloroplasts) and seems to play a crucial role in the biogenesis of photosynthetic membranes. In both case, the mechanism of action of the protein is enigmatic. We have visualised both proteins in vivo using fluorescence microscopy and fluorescent protein tags, and found that they form clusters near to the membrane under the conditions when they are likely to be physiologically active. Combined with biochemical identification of interaction partners under these conditions, this suggests a novel hypothesis: that both these proteins may help to organise assembly centres for the rapid and localised production of membrane and secreted proteins. A key prediction of this hypothesis is that specific mRNA molecules ...

Concerning heart failure (HF), the current COVID-19 pandemic is having a dramatic effect on the daily life of each individual, ranging from social distancing measures applied in most countries to getting severely diseased due to the virus. Cardiovascular Disease (CVD) is among the most common conditions in people that die of the infection. The burden of CVD accounts for over 60 million people in the EU alone, therefore, it is the leading cause of death in the world.. Although COVID-19 shows us the direct impact of a potential treatment for peoples health, CVD is a stealthy pandemic killer. HF is a chronic disease condition in which the heart is not able to fill properly or efficiently pump blood throughout your body, caused by different stress conditions including myocardial infarction, atherosclerosis, diabetes and high blood pressure. Several measures are commonly used to treat heart disease, such as lifestyle changes and medications like beta-blockers and ACE inhibitors, yet these typically ...

Tempering of martensite under simultaneous compressive stress has been studied within the temperature range of 20-400 deg C. Resistive heating was utilised to obtain rapid heating and cooling cycles of a few seconds. Material was obtained from a medium carbon pearlitic railway wheel steel, quench hardened to obtain martensitic structure. Above approx 150 deg C dilatation effects were observed below the global yielding point of the material. Microstraining around dislocations in the body centred tetragonal crystallographic structure or viscous flow at higher temperatures was a probable explanation to this material behaviour. Hence, external stress may have an important influence on the tempering progression of martensitic steel. The trials also showed that tempering of martensite progresses fast, is near instantaneous and is independent of the presence of external stress or not.

The main research interests in the lab will always gravitate towards the effects of environmental stress on organismal life history traits. To this end, we always have multiple projects running that involved environmental stress exposure (low or high temperature, dehydration, rehydration, overhydration, UV radiation, gamma radiation, X-ray radiation, anoxia, hypoxia, hyperoxia, infection, and long periods of activity). We study the effects of these stressors (single or multiple exposures) on immediate survival, development, activity, sexual performance, fertility and fecundity, and longevity. We normally avoid model organisms, as their stress physiology responses have been changed by years of lab rearing. We strive to find organisms that are uniquely suited for answering the questions at hand in the appropriate environment.. ...

The first time she was hospitalized, and the second time she somehow made it through on her own. I know how painful this can be and how helpless you must feel at times to help her. My heart goes out to you -- and to her.. Early onset Parkinsons requires tremendous coping skills, and your medications are definitely *not* just feel-good drugs but tools to improve your quality of life. If you dont mind my saying so, I think it is important to consider the possibility of changing how you think about these medications, for her sake as well as yours. There are amazing new medications available today that have revolutionized the treatment of psychosis, particularly of the type that you describe your wife as having. She really ...

Being sessile, plant are exposed to a range of stresses, of both abiotic and biotic origin, during the course of their life, and often simultaneously.
This perspective paper explores the utilization of abiotic stress-responsive transcription factors (TFs) from crassulacean acid metabolism (CAM) plants to improve abiotic stress tolerance in crop plants. CAM is a specialized type of photosynthetic adaptation that enhances water-use efficiency (WUE) by shifting CO2 uptake to all or part of the nighttime when evaporative water losses are minimal. Recent studies have shown that TF-based genetic engineering could be a useful approach for improving plant abiotic stress tolerance because of the role of TFs as master regulators of clusters of stress-responsive genes. Here, we explore the use of abiotic stress-responsive TFs from CAM plants to improve abiotic stress tolerance and WUE in crops by controlling the expression of gene cohorts that mediate drought-responsive adaptations. Recent research has revealed several TF families including AP2/ERF, MYB, WRKY, NAC, NF-Y, and bZIP that might regulate water-deficit stress responses and CAM in the inducible ...

Apigenin is a natural product in various Chinese herbs and exhibits high bioactivity, including anticancer, anti- inflammatory, and antifibrotic effects (27-29). In addition, previous studies have indicated that it also elicits neuroprotective effects (30,31). In the present study, depressive-like mice, induced by chronic restraint stress, were used to investigate the antidepressant effects of apigenin. Chronic restraint stress has become a widely employed rodent model for depression-like disorders (23,32-34). Fluoxetine was used as a positive control drug, and, similar to fluoxetine, apigenin was observed to increase sucrose preference and decrease the immobility time in behavioral tests. According to the cytotoxicity assay, apigenin is a safe and easily-accessed compound, widely used in various Chinese herbs and food. The findings of the present study suggested that apigenin can exert antidepressive effects in chronic restraint stress model mice.. Clinically, the degree of autophagy has been ...
This study demonstrates, with empirical evidence that experimental translocation leads to changes in the stress physiology of birds handled in a manner typical of many conservation activities. Furthermore, the effects of the progressive sequence of capture, handling, transport, captivity and release to a new location seem to be additive, meaning that the sequence of acute stressors typically associated with the process of translocation causes meaningful physiological stress in birds. Translocated chukar had decreased baseline CORT concentrations, a reduced capacity to mount a CORT response to an acute stressor, a decreased sensitivity to negative feedback and significant weight loss.. Interestingly, days elapsed prior to recapture was not associated with the magnitude of these changes, indicating that the changes to HPA function occurred quickly and persisted beyond the cessation of exposure to translocation-associated acute stressors. Unfortunately, our study did not allow follow-up beyond ...
Surgical stress is the systemic response to surgical injury and is characterized by activation of the sympathetic nervous system, endocrine responses as well as immunological and haematological changes. Measurement of surgical stress is used in anaesthesia, physiology and surgery. Analysis of the surgical stress response can be used for evaluation of surgical techniques and comparisons of different anaesthetic protocols. Moreover they can be performed both in the intraoperative or postoperative period. If there is a choice between different techniques for a surgical procedure, one method to evaluate and compare the surgical techniques is to subject one group of patients to one technique, and the other group of patients to another technique, after which the surgical stress responses triggered by the procedures are compared. The technique with the least surgical stress response is considered the best for the patient. Similarly, a group of patients can be subjected to a surgical procedure where one ...

Purpose: : Changes in retinal ganglion cell (RGC) gene expression are important metrics to evaluate the response of these cells to apoptotic and neuroprotective stimuli. We sought to develop a qPCR array to interrogate normal and stress-response gene expression for mouse RGCs that also complied with the Minimal Information required for Quantitative PCR Experiments (MIQE) guidelines. Methods: : RGC specific and select stress-response genes were identified from the literature. Primers were designed to bridge introns, contain 60% GC identity, and amplify approximately 200 bp of cDNA. All primers were tested for specificity at a common temperature. All amplimers were cloned and sequenced, confirming identity. Standard curve data was obtained from cloned cDNAs of all target genes. Experimental cDNAs were generated from retinas isolated from eyes after optic nerve crush, including eyes from mice treated with the HDAC inhibitor trichostatin A (TSA) and from different strains that exhibit different ...
Organisms and their cells are constantly exposed to environmental fluctuations. Among them are stressors, which can induce macromolecular damage that exceeds a set threshold, independent of the underlying cause. Stress responses are mechanisms used by organisms to adapt to and overcome stress stimuli. Different stressors or different intensities of stress trigger different cellular responses, namely induce cell repair mechanisms, induce cell responses that result in temporary adaptation to some stressors, induce autophagy or trigger cell death. Studies have reported life-prolonging effects of a wide variety of so-called stressors, such as oxidants, heat shock, some phytochemicals, ischemia, exercise and dietary energy restriction, hypergravity, etc. These stress responses, which result in enhanced defense and repair and even cross-resistance against multiple stressors, may have clinical use and will be discussed, while the emphasis will be on the effects/cross-effects of oxidants.
The adaptive response of cells to increased unfolded proteins within the endoplasmic reticulum, or the unfolded protein response (UPR), is a fundamental and conserved cellular survival mechanism. Cancer development is often associated with a range of cytotoxic conditions like hypoxia, nutrient deprivation, and pH changes. These conditions trigger a set of cellular stress response pathways including the ER-stress response. Many aspects of the endoplasmic reticulum (ER)-stress response are adaptive and protect tumor cells from cell death suggesting a crucial role in tumor growth. Much less is known about the role of ER-stress response pathways in early stages of cancer and tumor progression. IRE1α is a major transducer of the UPR and is an ER localized transmembrane protein kinase/RNase. When activated by ER stress IRE1α splices an internal sequence from the XBP1 mRNA to generate a new transcript encoding the active XBP1 transcription factor, a major regulator of the adaptive response to ER ...

Recent advances in neuroimaging technologies have rendered multimodal analysis of operators cognitive processes in complex task settings and environments increasingly more practical. In this exploratory study, we utilized optical brain imaging and mobile eye tracking technologies to investigate the behavioral and neurophysiological differences among expert and novice operators while they operated a human-machine interface in normal and adverse conditions. In congruence with related work, we observed that experts tended to have lower prefrontal oxygenation and exhibit gaze patterns that are better aligned with the optimal task sequence with shorter fixation durations as compared to novices. These trends reached statistical significance only in the adverse condition where the operators were prompted with an unexpected error message. Comparisons between hemodynamic and gaze measures before and after the error message indicated that experts neurophysiological response to the error involved a systematic
Plant growth and productivity are greatly affected by various stress factors. The molecular mechanisms of stress tolerance in plant species have been well established. Metabolic pathways involving the synthesis of metabolites such as polyamines, carbohydrates, proline and glycine betaine have been shown to be associated with stress tolerance. Introduction of the stress-induced genes involved in these pathways from tolerant species to sensitive plants seems to be a promising approach to confer stress tolerance in plants. In cases where single gene is not enough to confer tolerance, metabolic engineering necessitates the introduction of multiple transgenes in plants ...

N2 - When organisms are faced with changes in their environment, they are forced to respond, if they are to maintain optimal function. Especially ectotherms must deal with environmental changes in e.g. temperature on a regular basis, and thus their survival and reproductive success depend on their ability to respond on a behavioral, physiological, morphological and/or evolutionary level according to the environmental cues.At the same time, if populations are small and fragmented, and have limited gene flow, environmental change and environmental stress might interact with intrinsic genetic stress such as inbreeding and genetic drift, which can exacerbate the effects of one or more environmental stresses. ...
Background. Previously in line with the concept of a triune neuro-endocrine-immune complex we have been carried out integrated quantitative estimation of neuroendocrine and immune responses to chronic restraint stress at male rats. At the next stage, research has been conducted in this line on female rats. In this article we give the results of quantitative evaluation of neuroendocrine responses to chronic restraint stress.. Material and methods. The experiment has been conducted on 60 white female rats Wistar line weighing 230-300 g. 10 of these animals have not subjected to any influences and 50 of them subjected to moderated stress by daily 30-minute immobilization during 7 days. The day after the completion of stressing in rats of both groups the parameters of HRV, blood levels of hormones as well as blood and urine levels Ca, P, Na and K have been registered. The thickness of glomerular, fascicular and reticular zones in sections of the adrenal glands thas been measured under a ...
Heat shock transcription factors (HSFs) are stress-responsive proteins that activate the expression of heat shock genes and are highly conserved from bakers yeast to humans. Under basal conditions, the human HSF1 protein is maintained as an inactive monomer through intramolecular interactions between two coiled-coil domains and interactions with heat shock proteins; upon environmental, pharmacological, or physiological stress, HSF1 is converted to a homotrimer that binds to its cognate DNA binding site with high affinity. To dissect regions of HSF1 that make important contributions to the stability of the monomer under unstressed conditions, we have used functional complementation in bakers yeast as a facile assay system. Whereas wild-type human HSF1 is restrained as an inactive monomer in yeast that is unable to substitute for the essential yeast HSF protein, mutations in the linker region between the DNA binding domain and the first coiled-coil allow HSF1 to homotrimerize and rescue the ...

I took this brain research work only to avoid deadly diseases in human arises out of physiological stress triggered by the dead weight hands which got exposed through the medium of light after the invention of my Computer Medical Instrument patented in the year 1998 had revealed the facts. These deadly diseases such as Diabetes of Type-I and Type-II, Brain stroke, Coronary heart disease, chronic kidney failure, bowel disorder, arthritis, as well as Alzheimers and Parkinsons disease inclusive of all types of cancer just arises out of the dead weight hands, where one hand is stronger than the other hand that manifest the disease in the human brain in different ways out of physiological stress. So far nobody has understood from where these diseases are cropping up and the answer came when I correlated male elephant musth with that of human bipolar disorder gave the breakthrough mainly caused by physiological stress affecting the major portion of the brain that decelerates the brains voltage ...

In a multicellular organisms, it is not only essential to control the rate of cell division but also to control the rate of cell death of cells that are no longer needed. Programmed Cell death (PCD) is a bacterial stress response which leads to cell suicide mediated by an intracellular program and is responsible for eliminating unwanted or potentially harmful cells.. Chromosomal toxin-antitoxin module mazEF. mazEF is one of the toxin-antitoxin systems that have been found on the chromosomes of many bacteria including Escherichial coli that was discovered to play an important part in bacterial programmed cell death to regulate the amount of cells and to assist bacteria on coping with a stressful environment change.. The mazEF module consists of two adjacent genes, mazF and mazE. MazF is a stable, long-lived toxin while MazE is a labile antitoxin that is antagonizes MazF and are degraded in vivo by ClpPA serine protease. These two genes are co-expressed and the mazEF system is negatively ...
To investigate whether SIRT1 might be responsible for the ability of CR to protect the cells of animals from stress-induced apoptosis, we used an in vitro cell culture model that recapitulates key in vivo proliferative and phenotypic features of CR (22). In this system, cells are cultured in the presence of serum from calorically restricted rats, resulting in the induction of characteristic stress-response genes and the attenuation of stress-induced apoptosis (22). SIRT1 expression was ∼twofold higher in human embryonic kidney (HEK) 293T cells grown in the presence of CR serum as compared to cells grown in AL serum (Fig. 1B).. In worms, flies, and mice, mutations in the insulin/insulin-like growth factor 1 (IGF-1) pathway can extend life-span (6, 23). The levels of insulin and IGF-1 are 8- and 1.4-fold lower, respectively, in CR rodents as compared to AL rodents (22). To determine whether the induction of SIRT1 expression by CR serum was due, in part, to reduced levels of these factors, FaO ...
Living conditions of every organism are influenced by various factors at this time. Some of them have positive effect on organism, some negative. Basic condition for surviving is the ability to resist and adapt to changing metabolic and living conditions. Every single stress effect can lead to changes in metabolism but organisms have ability to develope sufficient mechanisms for stress response. Some of them are similar for all living organisms (enzyme production, endogenous primary stress metabolites) some of them are specific for certain organism or stress type. Cell stress response can be observed on different levels (proteomic, genomic, metabolomic). In proper conditions it can be used indrustrially. In this work, influences of various stress factors were studied. These factors were applied on selected organisms - carotenogenic yeast and plant materials. Yeast stress response was induced by osmotic and oxidation stress factors. Changes on proteomic level and in production of selected ...
Background and Aims: Mitochondrial diseases, generally regarded as disorders affecting the OXPHOS system, manifest in a variety of clinical phenotypes.D. melanogaster tko25taffords a model for OXPHOS deficiency, resulting from a decreased intramitochondrial translational capacity, and has phenotypic characteristics similar to those presented in many human mitochondrial diseases. Thetko25tmodel exhibits systematic changes in the expression of several genes associated with metabolism, stress response and reproduction, in response to OXPHOS deficiency. A set of the most highly up-regulated key metabolic stress-response genes, namelyCG11659,CG17192,Fbp1,Fbp2,Hsp22andImpL3, was chosen for analysis. The aims of the present study were to test nutritional effects on expression up-regulation and to determine, if down-regulation of these genes by RNAi has a specific influence on development or physiological functions oftko25tflies.

We know stress can take a toll on our lives and that limiting stress is important for long-term health, but how does stress affect our bodies, and most importantly what can we do about it?
In zebrafish, as in most vertebrates, three different isoforms of the hypoxia-inducible transcription factor, Hif-1α, Hif-2α, and Hif-3α, have been identified. The expression data of genes encoding these three proteins, as analyzed so far, show distinct expression patterns for all three isoforms during early development, under hypoxic conditions, and during exercise, suggesting differential roles for all three proteins under these different conditions. While isoform-specific functions for Hif-1α and Hif-2α have been identified in recent years, the role of Hif-3α remains somewhat elusive. Several studies mostly using mammalian cells or tissues discussed Hif-3α as a competitive inhibitor of Hif-1α and Hif-2α. In zebrafish, the expression changes for Hif-1α and Hif-3α observed during development and under environmental stress conditions do not support this hypothesis, and recent studies indicate that Hif-3α is also able to directly control transcriptional activity of certain genes. The ...
Triacylglycerols (TAGs) are esters formed from one glycerol and three fatty acids. TAGs are induced to accumulate in algal cells under environmental stress conditions including nutrient-limitation, hyperosmosis, and low temperature, for the storage of metabolic energy and carbon, and also for the consumption of excess energy (e.g., Hirai et al., 2016; Hayashi et al., 2017). Beside their physiological significance, the commercial utilization of algal TAG has been expected for the production of biodiesel, the methyl esters of fatty acids, from the aspect of carbon-neutral conception. The amounts of TAGs can be determined through quantitative measurement of their constituent fatty acids. This protocol consists of the following three parts: the first is the extraction of total lipids from algal cells with the use of organic solvents, chloroform and methanol, according to the method of Bligh and Dyer (1959), the second is the separation of TAG from the other lipid classes by thin-layer chromatography (TLC),

The invention relates to medicine and, in particular drugs for the treatment of neoplastic diseases, Allergy treatment, prevention and overall health of the person.. It is known that in many pathological processes is the development of chronic stress. In addition, such a basis can be and preactivate, and anti-stress reaction low and very low levels of reactivity. The removal of the body of these adverse conditions is the method of activation therapy.. Activation therapy shows almost everything, one for healing and prevention, the other for treatment, either independently or in conjunction with a variety of therapies and surgical interventions. Activation therapy shown to protect against the damaging action of factors of any nature, big loads, both physical and emotional, as well as to slow down aging. To invoke the desired anti-stress reactions to improve the functional state of the organism and the rise of resistance upon activation therapy currently uses a variety of biostimulants of plant and ...

Learn how stress changes respiration, impacting blood oxygenation and oxygen delivery, circulation, creation of internal pressure, hydration and elasticity of muscle and connective tissues, and support for posture.
While a suite of assays is available to biologists interested in measuring physiological stress, there is not a consensus as to the most reliable biomarker indicating an individual is experiencing an environmental stressor, especially on a chronic basis. Additionally there are many constraints (i.e., timing, effort, and cost) that impact which measure(s) of stress to use. We used meta-analysis to synthesize and compare available data associated with the response of two commonly used assays of physiological stress: heterophil:lymphocyte ratio (H/L) and circulating glucocorticoid concentration (GC). Because the studies where both measures were obtained centered in groups (i.e., birds and reptiles) where the primary GC is corticosterone (CORT), we only analyzed studies using those species which use CORT as the primary GC. We compared paired values of H/L and CORT from control (i.e., unstressed) and treatment (i.e., stressed) populations to test for differences between the ability of the two ...
Materials and Methods An indirect non-competitive ELISA immunoassay was developed based on the use of ELISA plates sensitised with TNF-α. The plates were incubated overnight at 4ºC using recombinant TNF-α from E. Coli at a concentration of 1 µg/ml. The immunoassay was validated in terms of calibration function (from 0.2 to 50.0 µg/ml), detection limit (0.06 µg/ml), precision as within-day reproducibility (relative standard deviation lesser than 10%), and accuracy as percentage of recovery (higher that 90%). The infliximab solutions of 10.0 mg/ml and 5.0 mg/ml in NaCl 0.9% were stored refrigerated at 4°C protected from daylight. The biological activity of these solutions was tested periodically up to 15 days by the ELISA method developed. The ELISA was also used to study the drug degradation in a stress study involving the exposure of samples of infliximab (50.0 mg/ml) for 24 hours to different stress conditions: basicity (NaOH 0.1M), acidity (HCl 0.1M), oxidation (H2O2 1% and 10%), ...
The engulfment of a proto-mitochondrion by a primitive unicellular organism gave rise to the first eukaryotic cell, and ever since, mitochondrial function has been a vital aspect of eukaryotic life. Under conditions of physiological stress, the mitochondrion is far from a passive bystander, instead playing a key role in signalling pathways and the cellular responses they elicit. In this thematic series of Extreme Physiology & Medicine, the role of the mitochondrion in the response to physiological stress will be considered anew, through research articles, reviews, viewpoints and methodology papers that aim to reposition the organelle as a key player in the human response to a wide range of extreme conditions.
Comparative biochemistry demonstrates that the metabolites, complex biochemical networks, enzymes and regulatory mechanisms essential to all living cells are conserved in amazing detail throughout evolution. Thus, in order to evolve, an organism must overcome new adverse conditions without creating different but equally dangerous alterations in its ongoing successful metabolic relationship with its environment. Evidence suggests that stable long-term acquisitive evolution results from minor increases in mutation rates of genes related to a particular stress, with minimal disturbance to the balanced and resilient metabolism critical for responding to an unpredictable environment. Microorganisms have evolved specific biochemical feedback mechanisms that direct mutations to genes derepressed by starvation or other stressors in their environment. Transcription of the activated genes creates localized supercoiling and DNA secondary structures with unpaired bases vulnerable to mutation. The resulting ...
A research team of TU Dresden and Max-Planck researchers have been awarded 1.3 Mill. Euro in research funding from the VolkswagenStiftung. The researchers will use this funding to study how cells enter a dormant state when exposed to adverse conditions. Dresden. Life-threatening conditions like a lack of water, oxygen or food lead to a dysfunctional metabolism in most living beings. At worst, such conditions can lead to the death of cells and tissue. However, it is known that some cells can enter a kind of standby mode called dormancy. During this mode, life-threatening conditions seem to have no influence on them. Cell activity is reduced to a minimum in dormant cells, which seem to be in an intermediate state between life and death. Metabolism, growth and reproduction cease to occur, but when dormant cells re-encounter favourable environmental conditions these life-sustaining biological processes are reactivated. In other words, if the missing resource, like water or food, is once again ...

The device may determine the level of blood constituent, may use this level for monitoring and/or to activate an alarm when the level falls outside a predetermined range, may be applied to monitoring conditions of apnea, respiratory stress, and reduced blood flow in organ regions, heart rate, jaundice, and blood flow velocity, and may be incorporated within a monitoring system.
The folding state of polypeptides is easily perturbed by adverse conditions. Misfolded proteins are non-functional and lead to a measure of inefficiency in the cells economy. Their presence has additional consequences that are unrelated to loss-of-function features as numerous genetic and biochemical observations suggest that structures elaborated by polypeptides that fail to attain their proper three dimensional structure have deleterious gain-of-function effects on cell function. This process, also referred to as proteotoxicity, appears to be particularly important to the fate of non-renewable cells of long-lived organisms in which accumulating misfolded proteins can act over extended periods of time. The hypothesized contribution of such proteotoxins to cellular dysfunction fits our intuitive notions of aging as a time and use-dependent process. The progressive aging of the human population has led to an increase in the incidence of diseases hypothesized to be associated with various ...

One of the hallmarks in the advancement of cancer cells is an ability to overcome and acquire resistance to adverse conditions. There has been a large amount of cancer research on IGFBP-3 as a pro-apoptotic molecule in vitro. These pro-apoptotic properties, however, do not correlate with several studies linking high IGFBP-3 levels in breast cancer tissue to rapid growth and poor prognosis. Evidence is emerging that IGFBP-3 also exhibits pro-survival and growth-promoting properties in vitro. How IGFBP-3 pivots cell fate to either death or survival, it seems, comes down to a complex interplay between cells microenvironments and the presence of cellular IGFBP-3 binding partners and growth factor receptors. The cytoprotective actions of IGFBP-3 are not restricted to cancer but are also observed in other disease states, such as retinopathy and brain ischaemia. Here we review the literature on this paradoxical nature of IGFBP-3, its pro-apoptotic and growth-inhibitory actions versus its cytoprotective and
S-cysteinylated albumin and methionine-oxidized apolipoprotein A-I (apoA-I) have been posed as candidate markers of diseases associated with oxidative stress. Here, a dilute-and-shoot form of LC-electrospray ionization-MS requiring half a microliter of blood plasma was employed to simultaneously quantify the relative abundance of these oxidized proteoforms in samples stored at −80 °C, −20 °C, and room temperature and exposed to multiple freeze-thaw cycles and other adverse conditions in order to assess the possibility that protein oxidation may occur as a result of poor sample storage or handling. Samples from a healthy donor and a participant with poorly controlled type 2 diabetes .... ...

In vitro stress assays are commonly used to study responses of plants to abiotic stress and to assess stress tolerance. A literature review reveals that most studies use very high stress levels, and measure criteria such as germination, plant survival, or development of visual symptoms such as bleaching. However, we show that these parameters are indicators of very severe stress, and such studies thus only provide incomplete information about stress sensitivity. Similarly, transcript analysis revealed that typical stress markers are only induced at high stress levels in young seedlings. Therefore, tools are needed to study the effects of mild stress. We found that the commonly used stress-inducing agents mannitol, sorbitol, NaCl and H2O2 impact shoot growth in a highly specific and dose-dependent way. Therefore, shoot growth is a sensitive, relevant and easily measured phenotype to assess stress tolerance over a wide range of stress levels. Finally, our data suggest that care should be taken ...
