Stress physiology and inflammation

وَنُوحًا إِذۡ نَادَىٰ مِن قَبۡلُ فَٱسۡتَجَبۡنَا لَهُۥ فَنَجَّيۡنَٰهُ وَأَهۡلَهُۥ مِنَ ٱلۡكَرۡبِ ٱلۡعَظِيمِ

Long before that, We answered Noah when he cried out to Us: We saved him and his family from the great calamity

وَنَجَّيۡنَٰهُمَا وَقَوۡمَهُمَا مِنَ ٱلۡكَرۡبِ ٱلۡعَظِيمِ

We saved them and their people from great distress

وَنَجَّيۡنَٰهُ وَأَهۡلَهُۥ مِنَ ٱلۡكَرۡبِ ٱلۡعَظِيمِ

We saved him and his people from great distress

قُلِ ٱللَّهُ يُنَجِّيكُم مِّنۡهَا وَمِن كُلِّ كَرۡبࣲ ثُمَّ أَنتُمۡ تُشۡرِكُونَ

Say, ‘God rescues you from this and every distress; yet still you worship others beside Him.’

وَلَمَّا بَلَغَ أَشُدَّهُۥٓ ءَاتَيۡنَٰهُ حُكۡمࣰ ا وَعِلۡمࣰ اۚ وَكَذَٰلِكَ نَجۡزِي ٱلۡمُحۡسِنِينَ

When he reached maturity, We gave him judgement and knowledge: this is how We reward those who do good

وَلَا تَقۡرَبُواْ مَالَ ٱلۡيَتِيمِ إِلَّا بِٱلَّتِي هِيَ أَحۡسَنُ حَتَّىٰ يَبۡلُغَ أَشُدَّهُۥۚ وَأَوۡفُواْ ٱلۡكَيۡلَ وَٱلۡمِيزَانَ بِٱلۡقِسۡطِۖ لَا نُكَلِّفُ نَفۡسًا إِلَّا وُسۡعَهَاۖ وَإِذَا قُلۡتُمۡ فَٱعۡدِلُواْ وَلَوۡ كَانَ ذَا قُرۡبَىٰۖ وَبِعَهۡدِ ٱللَّهِ أَوۡفُواْۚ ذَٰلِكُمۡ وَصَّىٰكُم بِهِۦ لَعَلَّكُمۡ تَذَكَّرُونَ

Stay well away from the property of orphans, except with the best [intentions], until they come of age; give full measure and weight, according to justice’- We do not burden any soul with more than it can bear- ‘ when you speak, be just, even if it concerns a relative; keep any promises you make in God’s name. This is what He commands you to do, so that you may take heed’

And mention Noah what follows Nūhan substitutes for it when he called when he supplicated to God against his people — with the words My Lord do not leave upon the earth any inhabitant from among the disbelievers … to the end of the verse Q. 7126 before that is before the time of Abraham and Lot. And We responded to him and delivered him and his people who were in the Ark with him from the great agony namely from drowning and his people’s denial of him.

and We delivered them and their people the Children of Israel from the great distress namely Pharaoh’s enslavement of them.

And We delivered him and his family from the great distress which was the drowning

And (remember) Nuh, when he cried (to Us) aforetime. We answered to his invocation and saved him and his family from the great distress (76)We helped him against the people who denied Our Ayat. Verily, they were a people given to evil. So We drowned them all (77) Nuh and His People Allah tells us how He responded to His servant and Messenger Nuh, peace be upon him, when he prayed to Him against his people for their disbelief in him: فَدَعَا رَبَّهُ أَنِّي مَغْلُوبٌ فَانتَصِرْ (Then he invoked his Lord (saying): "I have been overcome, so help (me)!")(54:10) وَقَالَ نُوحٌ رَّبِّ لَا تَذَرْ عَلَى الْأَرْضِ مِنَ الْكَافِرِينَ دَيَّارًا - إِنَّكَ إِن تَذَرْهُمْ يُضِلُّوا عِبَادَكَ وَلَا يَلِدُوا إِلَّا فَاجِرًا كَفَّارًا (And Nuh said: "My Lord! Leave not any inhabitant of the disbelievers on the earth! If You leave them, they will mislead Your servants, and they will beget none but wic

And, indeed We gave Our grace to Musa and Harun (114)And We saved them and their people from the great distress (115)And helped them, so that they became the victors (116)And We gave them the clear Scripture (117)And guided them to the right path (118)And We left for them among the later generations (119)"Salam (peace!) be upon Musa and Harun! (120)Verily, thus do We reward the doers of good (121)Verily, they were two of Our believing servants (122) Musa and Harun Allah tells us how He blessed Musa and Harun with prophethood and how He saved them, along with those who believed, from the oppression of Fir'awn and his people, who had persecuted them by killing their sons and sparing their women, and by forcing them to do the most menial tasks, then ultimately He caused them to prevail over them and to seize their lands and their wealth and all that they had spent their entire lives amass

And indeed Nuh invoked Us, and We are the best of those who answer (75)And We rescued him and his family from the great distress (76)And, his progeny, them We made the survivors (77)And left for him (a goodly remembrance) among the later generation (78)"Salam (peace!) be upon Nuh among the all creatures! (79)Verily, thus We reward the gooddoers (80)Verily, he [Nuh] was one of Our believing servants (81)Then We drowned the others (82) Nuh and His People When Allah tells us about how most of the early people went astray from the path of salvation, He starts the detailed explanation of that with the story of Nuh and the rejection of his people. Only a few of Nuh's people believed in him, despite the long period of time he spent among them. He stayed among them for one thousand years less fifty, and after he stayed among them for so long and their disbelief became too much for him to bear

حَدَّثَنِي عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ عَمْرٍو، حَدَّثَنَا زُهَيْرُ بْنُ مُحَمَّدٍ، عَنْ مُحَمَّدِ بْنِ عَمْرِو بْنِ حَلْحَلَةَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، وَعَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ مَا يُصِيبُ الْمُسْلِمَ مِنْ نَصَبٍ وَلاَ وَصَبٍ وَلاَ هَمٍّ وَلاَ حُزْنٍ وَلاَ أَذًى وَلاَ غَمٍّ حَتَّى الشَّوْكَةِ يُشَاكُهَا، إِلاَّ كَفَّرَ اللَّهُ بِهَا مِنْ خَطَايَاهُ ‏"‏‏.‏

Narrated Abu Sa`id Al-Khudri and Abu Huraira:The Prophet (ﷺ) said, "No fatigue, nor disease, nor sorrow, nor sadness, nor hurt, nor distress befalls a Muslim, even if it were the prick he receives from a thorn, but that Allah expiates some of his sins for that

حَدَّثَنَا إِبْرَاهِيمُ بْنُ الْمُنْذِرِ، قَالَ حَدَّثَنِي مُحَمَّدُ بْنُ فُلَيْحٍ، قَالَ حَدَّثَنِي أَبِي، عَنْ هِلاَلِ بْنِ عَلِيٍّ، مِنْ بَنِي عَامِرِ بْنِ لُؤَىٍّ عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ مَثَلُ الْمُؤْمِنِ كَمَثَلِ الْخَامَةِ مِنَ الزَّرْعِ مِنْ حَيْثُ أَتَتْهَا الرِّيحُ كَفَأَتْهَا، فَإِذَا اعْتَدَلَتْ تَكَفَّأُ بِالْبَلاَءِ، وَالْفَاجِرُ كَالأَرْزَةِ صَمَّاءَ مُعْتَدِلَةً حَتَّى يَقْصِمَهَا اللَّهُ إِذَا شَاءَ ‏"‏‏.‏

Narrated Abu Huraira:Allah's Messenger (ﷺ) said, "The example of a believer is that of a fresh tender plant; from whatever direction the wind comes, it bends it, but when the wind becomes quiet, it becomes straight again. Similarly, a believer is afflicted with calamities (but he remains patient till Allah removes his difficulties.) And an impious wicked person is like a pine tree which keeps hard and straight till Allah cuts (breaks) it down when He wishes." (See Hadith No. 558, Vol)

Umm Al-Mundhir said:"The Messenger of Allah (ﷺ) entered upon me, while `Ali was with him, and we had a cluster of unripe dates hanging." She said: "The Messenger of Allah (ﷺ) began eating, and `Ali ate with him. The Messenger of Allah (ﷺ) said to `Ali: 'Stop, stop, for you are still recovering.' So `Ali sat and the Prophet (ﷺ) ate." She said: "I made some chard and barley for them, so the Prophet (ﷺ) said: 'O `Ali eat from this, for indeed it will be more suitable for you." Another chain reports a similar narration

Disruption of multisystem responses to stress in type 2 diabetes: investigating the dynamics of allostatic load.: Psychological stress-related processes are thought to contribute to the development and progression of type 2 diabetes, but the biological mechanisms involved are poorly understood. Here, we tested the notion that people with type 2 diabetes experience chronic allostatic load, manifest as dynamic disturbances in reactivity to and recovery from stress across multiple (cardiovascular, neuroendocrine, inflammatory, metabolic) biological systems, coupled with heightened experience of chronic life st

Intravenous Infusion of Cortisol, Adrenaline, or Noradrenaline Alters Porcine Immune Cell Numbers and Promotes Innate over Adaptive Immune Functionality.

Despite the importance of pigs (Sus scrofa domestica) in livestock production and their increasing role as a model organism for human physiology, knowledge about the porcine immune system under the influence of stress hormones is fragmentary. Exceptionally little is known about the effects of catecholamines. Therefore, the aim of this study was to examine the in vivo effects of adrenaline, noradrenaline, and cortisol on number and functionality of porcine blood immune cells. Castrated male pigs (n = 34) were treated with physiological doses of either adrenaline, noradrenaline, or cortisol via i.v. infusion for 48 h. Blood samples were collected before treatment (-24 h, -22 h, 0 h), during treatment (+2 h, +24 h, +48 h), and at 72 h postinfusion. Immune cell numbers and phagocytic activity were evaluated by flow cytometry and lymphocyte proliferation by 3H-thymidine incorporation. Total I…

Thymoquinone Protects against Hyperlipidemia-Induced Cardiac Damage in Low-Density Lipoprotein Receptor-Deficient (LDL-R-/-) Mice via Its Anti-inflammatory and Antipyroptotic Effects.

Hyperlipidemia is a risk factor for cardiac damage and cardiovascular disease. Increasing evidence has shown that dyslipidemia-related cardiac damage is associated with lipid accumulation, oxidative stress, and inflammation. Thymoquinone (TQ) is the major constituent of Nigella sativa, commonly known as black seed or black cumin, and is globally used in folk (herbal) medicine for treating and preventing a number of diseases and conditions. Several studies have shown that TQ can protect against cardiac damage. This study is aimed at investigating the possible protective effects of TQ on hyperlipidemia-induced cardiac damage in low-density lipoprotein receptor-deficient (LDL-R-/-) mice. Eight-week-old male LDL-R-/- mice were randomly divided into normal diet (ND), high-fat diet (HFD), and HFD and TQ (HFD+TQ) groups and were fed the different diets for eight weeks. Blood samples were obtain…

Bee honey protects astrocytes against oxidative stress: A preliminary in vitro investigation.

Aim: Bee honey is widely used as a bioactive food to improve general health and produce therapeutic benefits in various physical disorders. It also improves cognitive and mood-related behaviors and symptoms in mice and humans. Still, its direct effect on brain cells is unclear. Here, we examined the effect of whole honey on the survival of astrocytes exposed to oxidative stress. Methods: Cultured cortical astrocytes were treated with honey (0.1%, 0.3%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, 3%, and 5% [v/v]) for 24 hours followed by H2 O2 (100 μmol/L) for 3 hours. Cellular viability was assessed with MTT assay. Results: Honey prevented cellular death in a dose-dependent manner compared with H2 O2- treated cells. Honey at 1% concentration had the most significant effect (P = .015). Conclusion: Bee honey exerts a neuroprotective effect through its antioxidant activity.

Early-life social environment predicts social network position in wild zebra finches.

Early-life experience can fundamentally shape individual life-history trajectories. Previous research has suggested that exposure to stress during development causes differences in social behaviour later in life. In captivity, juvenile zebra finches exposed to elevated corticosterone levels were less socially choosy and more central in their social networks when compared to untreated siblings. These differences extended to other aspects of social life, with 'stress-exposed' juveniles switching social learning strategies and juvenile males less faithfully learning their father's song. However, while this body of research suggests that the impacts of early-life stress could be profound, it remains unknown whether such effects are strong enough to be expressed under natural conditions. Here, we collected data on social associations of zebra finches in the Australian desert after experimenta…

Maternal prenatal stress phenotypes associate with fetal neurodevelopment and birth outcomes.

Maternal prenatal stress influences offspring neurodevelopment and birth outcomes including the ratio of males to females born; however, there is limited understanding of what types of stress matter, and for whom. Using a data-driven approach with 27 variables from questionnaires, ambulatory diaries, and physical assessments collected early in the singleton pregnancies of 187 women, 3 latent profiles of maternal prenatal stress emerged that were differentially associated with sex at birth, birth outcomes, and fetal neurodevelopment. Most women (66.8%) were in the healthy group (HG); 17.1% were in the psychologically stressed group (PSYG), evidencing clinically meaningful elevations in perceived stress, depression, and anxiety; and 16% were in the physically stressed group (PHSG) with relatively higher ambulatory blood pressure and increased caloric intake. The population normative male:f…

Distinct cytokine profiles in human brains resilient to Alzheimer's pathology.

Our group has previously studied the brains of some unique individuals who are able to tolerate robust amounts of Alzheimer's pathological lesions (amyloid plaques and neurofibrillary tangles) without experiencing dementia while alive. These rare resilient cases do not demonstrate the patterns of neuronal/synaptic loss that are normally found in the brains of typical demented Alzheimer's patients. Moreover, they exhibit decreased astrocyte and microglial activation markers GFAP and CD68, suggesting that a suppressed neuroinflammatory response may be implicated in human brain resilience to Alzheimer's pathology. In the present work, we used a multiplexed immunoassay to profile a panel of 27 cytokines in the brains of controls, typical demented Alzheimer's cases, and two groups of resilient cases, which possessed pathology consistent with either high probability (HP, Braak stage V-VI and C…

Protective effect of thymoquinone, the main component of Nigella Sativa, against diazinon cardio-toxicity in rats.

Several studies have shown that oxidative stress and cell damage can occur at very early stages of diazinon (DZN) exposure. The present study was designed to determine the beneficial effect of thymoquinone (Thy), the main component of Nigella sativa (black seed or black cumin), against DZN cardio-toxicity in rats. In the present experimental study, 48 male Wistar rats were randomly divided into six groups: control (corn oil gavages), DZN gavages (20 mg/kg/day), Thy gavages (10 mg/kg/day) and Thy + DVN gavages (2.5, 5 and 10 mg/kg/day). Treatments were continued for 28 days, then the animals were anesthetized by ether and superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST), lactate dehydrogenize (LDH) and glutathione peroxide (GPX) activity was evaluated. In addition, glutathione (GSH) and malondialdehyde (MDA) the heart tissue and creatinephosphokinase-MB (CPK-MB)…

The protective effect of 20(S)-protopanaxadiol (PPD) against chronic sleep deprivation (CSD)-induced memory impairments in mice.

Sleep deprivation (SD) is associated with oxidative stress that causes learning and memory impairment. 20(S)-Protopanaxadiol (PPD), one of the protopanaxadiol-type saponins, has antioxidant and neuroprotective effect. This study was designed to research the protective effect of PPD against cognitive deficits induced by chronic sleep deprivation (CSD) in mice. The CSD model was induced by subjecting the mice to our self-made Sleep Interruption Apparatus (SIA) continuously for 14 days. The memory enhancing effects of PPD were evaluated by behavioral tests and the related mechanism was further explored by observing the oxidative stress changes in the cortex and hippocampus of mice. The results revealed that PPD (20 and 40 μmol/kg, i.p.) administration significantly improved the cognitive performance of CSD model mice in object location recognition experiment, novel object recognition task a…

Deficits in empathy have been proposed to constitute a hallmark of several psychiatric disturbances like conduct disorder, antisocial and narcissistic personality disorders. Limited sensitivity to punishment, shallow or deficient affect and reduced physiological reactivity to environmental stressors have been often reported to co-occur with limited empathy and contribute to the onset of antisocial phenotypes. Empathy in its simplest form (i.e. emotional contagion) is addressed in preclinical models through the evaluation of the social transmission of emotional states: mice exposed to a painful stimulus display a higher response if in the presence of a familiar individual experiencing a higher degree of discomfort, than in isolation. In the present study, we investigated whether a reduction of emotional contagion can be considered a predictor of reduced sociality, sensitivity to punishmen…

Stress is associated with an increased risk of recurrent seizures in adults.

Objective: The literature is sparse on the complex interrelationships between stressors, depression, anxiety disorders, and epilepsy. We hypothesized that a relationship exists between stress and epilepsy. We evaluated whether markers of stress are associated with seizure recurrence in a low income community-based cohort of adults with single unprovoked seizure or newly diagnosed epilepsy. Methods: We ascertained adult residents of Northern Manhattan and Harlem, New York City, with a first unprovoked seizure or newly diagnosed epilepsy, between December 2010 and January 2013. At enrollment, we collected information about seizure phenomenology, demographics, clinical information, and measures of stress (environmental stress, stressful life events, facets of allostatic load-i.e., the cumulative effect of adaptation to stress, psychiatric disorders, and low collective efficacy). Collective …

Prevalence and Associated Factors of Depression in General Population of Korea: Results from the Korea National Health and Nutrition Examination Survey, 2014.

Depressive disorder is a common mental illness and remains a major cause of morbidity worldwide. The present study, a cross-sectional, nationwide, population-based survey assessed the prevalence of depression in the general population of Korea through a random sampling of the non-institutionalized population for the Korea National Health and Nutrition Examination Survey (KNHANES) VI. The Patient Health Questionnaire (PHQ)-9 was first introduced into the KNHANES to detect depression. The point prevalence of depression (PHQ score of 10 or higher) was 6.7% (95% confidence interval [CI], 5.7-7.6) in 4,949 subjects. Based on the analysis using the diagnostic algorithm of the PHQ-9, the prevalence of major depressive disorder was 2.7% (95% CI, 2.2-3.3). Multiple logistic regression analysis, after adjusting the sociodemographic variables, also showed that the factors associated with depression…

Transgenerational epimutations induced by multi-generation drought imposition mediate rice plant's adaptation to drought condition.

Epigenetic mechanisms are crucial mediators of appropriate plant reactions to adverse environments, but their involvement in long-term adaptation is less clear. Here, we established two rice epimutation accumulation lines by applying drought conditions to 11 successive generations of two rice varieties. We took advantage of recent technical advances to examine the role of DNA methylation variations on rice adaptation to drought stress. We found that multi-generational drought improved the drought adaptability of offspring in upland fields. At single-base resolution, we discovered non-random appearance of drought-induced epimutations. Moreover, we found that a high proportion of drought-induced epimutations maintained their altered DNA methylation status in advanced generations. In addition, genes related to transgenerational epimutations directly participated in stress-responsive pathway…

Microbiota modulation counteracts Alzheimer's disease progression influencing neuronal proteolysis and gut hormones plasma levels.

Gut microbiota has a proven role in regulating multiple neuro-chemical pathways through the highly interconnected gut-brain axis. Oral bacteriotherapy thus has potential in the treatment of central nervous system-related pathologies, such as Alzheimer's disease (AD). Current AD treatments aim to prevent onset, delay progression and ameliorate symptoms. In this work, 3xTg-AD mice in the early stage of AD were treated with SLAB51 probiotic formulation, thereby affecting the composition of gut microbiota and its metabolites. This influenced plasma concentration of inflammatory cytokines and key metabolic hormones considered therapeutic targets in neurodegeneration. Treated mice showed partial restoration of two impaired neuronal proteolytic pathways (the ubiquitin proteasome system and autophagy). Their cognitive decline was decreased compared with controls, due to a reduction in brain dama…

Exploring the Effect of Ginsenoside Rh1 in a Sleep Deprivation-Induced Mouse Memory Impairment Model.

Panax ginseng C.A. Meyer (Araliaceae) has been used in traditional Chinese medicine for enhancing cognition for thousands of years. Ginsenoside Rh1, a constituent of ginseng root, as with other constituents, has memory-improving effects in normal mice and scopolamine-induced amnesic mice. Sleep deprivation (SD) is associated with memory impairment through induction of oxidative stress. The present study investigated the effect of Rh1 against SD-induced cognitive impairment and attempted to define the possible mechanisms involved. Ginsenoside Rh1 (20 μmol/kg; 40 μmol/kg) and modafinil (0.42 g/kg) were administered to the mice intraperitoneally for 23 days. After 14-day SD, locomotor activity was examined using the open field test, and the object location recognition and Morris water maze tests were used to evaluate cognitive ability. The cortex and hippocampus were then dissected and homo…

Exhausting Physicians Employed in Hospitals in Japan Assessed by a Health Questionnaire.

Objective: Japanese physicians employed and working in general hospitals have become busier since 2005, as they had to teach and guide the increased number of medical residents graduated from medical schools. Working hours and chronic fatigue of employed physicians were surveyed compared with independent physicians working in their own out-patient clinics and with usual employed men in Japan, and their mental health was assessed. Methods: (1) 75 employed physicians in hospitals were surveyed of their working hours a week and compared with (2) 48 independent general practitioners (GP) who work in their own out-patient clinics. (3) 47 employed physicians aged 40s and 50s out of (1) were compared with group (4) or 277 men of the same age employed in an automobile company. A symptom check list questionnaire, the Total Health Index (THI), was used to assess their stress and mental health stat…

Maternal Exposure to Childhood Trauma Is Associated During Pregnancy With Placental-Fetal Stress Physiology.

Background: The effects of exposure to childhood trauma (CT) may be transmitted across generations; however, the time period(s) and mechanism(s) have yet to be clarified. We address the hypothesis that intergenerational transmission may begin during intrauterine life via the effect of maternal CT exposure on placental-fetal stress physiology, specifically placental corticotropin-releasing hormone (pCRH). Methods: The study was conducted in a sociodemographically diverse cohort of 295 pregnant women. CT exposure was assessed using the Childhood Trauma Questionnaire. Placental CRH concentrations were quantified in maternal blood collected serially over the course of gestation. Linear mixed effects and Bayesian piece-wise linear models were employed to test hypothesized relationships. Results: Maternal CT exposure (CT+) was significantly associated with pCRH production. Compared with nonexp…

Psychotropic effects of Lactobacillus plantarum PS128 in early life-stressed and naïve adult mice.

Ingestion of specific probiotics, namely "psychobiotics", produces psychotropic effects on behavior and affects the hypothalamic-pituitary-adrenal axis and neurochemicals in the brain. We examined the psychotropic effects of a potential psychobiotic bacterium, Lactobacillus plantarum strain PS128 (PS128), on mice subjected to early life stress (ELS) and on naïve adult mice. Behavioral tests revealed that chronic ingestion of PS128 increased the locomotor activities in both ELS and naïve adult mice in the open field test. In the elevated plus maze, PS128 significantly reduced the anxiety-like behaviors in naïve adult mice but not in the ELS mice; whereas the depression-like behaviors were reduced in ELS mice but not in naïve mice in forced swimming test and sucrose preference test. PS128 administration also reduced ELS-induced elevation of serum corticosterone under both basal and stresse…

An active inference theory of allostasis and interoception in depression.

In this paper, we integrate recent theoretical and empirical developments in predictive coding and active inference accounts of interoception (including the Embodied Predictive Interoception Coding model) with working hypotheses from the theory of constructed emotion to propose a biologically plausible unified theory of the mind that places metabolism and energy regulation (i.e. allostasis), as well as the sensory consequences of that regulation (i.e. interoception), at its core. We then consider the implications of this approach for understanding depression. We speculate that depression is a disorder of allostasis, whose myriad symptoms result from a 'locked in' brain that is relatively insensitive to its sensory context. We conclude with a brief discussion of the ways our approach might reveal new insights for the treatment of depression. This article is part of the themed issue 'Inter…

Hypothalamic CRH neurons orchestrate complex behaviours after stress.

All organisms possess innate behavioural and physiological programmes that ensure survival. In order to have maximum adaptive benefit, these programmes must be sufficiently flexible to account for changes in the environment. Here we show that hypothalamic CRH neurons orchestrate an environmentally flexible repertoire of behaviours that emerge after acute stress in mice. Optical silencing of CRH neurons disrupts the organization of individual behaviours after acute stress. These behavioural patterns shift according to the environment after stress, but this environmental sensitivity is blunted by activation of PVN CRH neurons. These findings provide evidence that PVN CRH cells are part of a previously unexplored circuit that matches precise behavioural patterns to environmental context following stress. Overactivity in this network in the absence of stress may contribute to environmental a…

Transgenerational epigenetic programming via sperm microRNA recapitulates effects of paternal stress.

Epigenetic signatures in germ cells, capable of both responding to the parental environment and shaping offspring neurodevelopment, are uniquely positioned to mediate transgenerational outcomes. However, molecular mechanisms by which these marks may communicate experience-dependent information across generations are currently unknown. In our model of chronic paternal stress, we previously identified nine microRNAs (miRs) that were increased in the sperm of stressed sires and associated with reduced hypothalamic-pituitary-adrenal (HPA) stress axis reactivity in offspring. In the current study, we rigorously examine the hypothesis that these sperm miRs function postfertilization to alter offspring stress responsivity and, using zygote microinjection of the nine specific miRs, demonstrated a remarkable recapitulation of the offspring stress dysregulation phenotype. Further, we associated lo…

Psychological and physiological stress negatively impacts early engagement and retention of opioid-dependent individuals on methadone maintenance.

The present study investigated whether psychological and/or physiological measures of stress would impede induction onto methadone maintenance and predict early (<6 months) discontinuation. Compared with controls, opioid-dependent subjects displayed increased distress on the perceived stress scale (PSS) and post-traumatic stress disorder checklist (PCLC); 60% exhibited abnormal cortisol. Addiction severity index (ASI), drug-use, and stress indices explained between 17 and 37% of the variance in engagement including attendance, opioid abstinence, and methadone stabilization. Participants who discontinued treatment displayed poor engagement, abnormal cortisol, elevated withdrawal symptoms, higher distress, and increased ongoing opioid use versus compliant individuals. Discontinuation was initially related to drug-use severity; however, by 6 months, retention depended primarily upon cortiso…

An experimental demonstration that early-life competitive disadvantage accelerates telomere loss.

Adverse experiences in early life can exert powerful delayed effects on adult survival and health. Telomere attrition is a potentially important mechanism in such effects. One source of early-life adversity is the stress caused by competitive disadvantage. Although previous avian experiments suggest that competitive disadvantage may accelerate telomere attrition, they do not clearly isolate the effects of competitive disadvantage from other sources of variation. Here, we present data from an experiment in European starlings (Sturnus vulgaris) that used cross-fostering to expose siblings to divergent early experience. Birds were assigned either to competitive advantage (being larger than their brood competitors) or competitive disadvantage (being smaller than their brood competitors) between days 3 and 12 post-hatching. Disadvantage did not affect weight gain, but it increased telomere at…
