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’
Commentary on the verses above, at most two editions per verse.
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

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

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)

Cumulative meta-analysis of interleukins 6 and 1β, tumour necrosis factor α and C-reactive protein in patients with major depressive disorder.: Cumulative meta-analyses are used to evaluate the extent to which further studies are needed to confirm or refute a hypothesis. We used this approach to assess observational evidence on systemic inflammation in individuals with major depressive disorder. We identified 58 studies of four common inflammatory markers in a literature search of PubMed, Embase and PsychInfo databases in May 2014. Pooled data from the earliest eight studies already showed an association between interleukin-6 concentrat
Towards a consensus definition of allostatic load: a multi-cohort, multi-system, multi-biomarker individual participant data (IPD) meta-analysis.: Background: Allostatic load (AL) is a multi-system composite index for quantifying physiological dysregulation caused by life course stressors.

Sympathetic nervous system dysfunction in fibromyalgia, chronic fatigue syndrome, irritable bowel syndrome, and interstitial cystitis: a review of case-control studies.
Background: Fibromyalgia often coexists and overlaps with other syndromes such as chronic fatigue, irritable bowel syndrome, and interstitial cystitis. Chronic stress has been implicated in the pathogenesis of these illnesses. The sympathetic nervous system is a key element of the stress response system. Sympathetic dysfunction has been reported in these syndromes, raising the possibility that such dysautonomia could be their common clustering underlying pathogenesis. Objective: The objective of this study was to carry out a review of all published comparative case-control studies investigating sympathetic nervous system performance in fibromyalgia, chronic fatigue syndrome, irritable bowel syndrome, and interstitial cystitis. Methods: Online databases PubMed and EMBASE were accessed using the following key words: autonomic (OR) sympathetic (AND) fibromyalgia, chronic fatigue syndrome, i…

Sex differences in the HPA axis.
The hypothalamic-pituitary-adrenal (HPA) axis is a major component of the systems that respond to stress, by coordinating the neuroendocrine and autonomic responses. Tightly controlled regulation of HPA responses is critical for maintaining mental and physical health, as hyper- and hypo-activity have been linked to disease states. A long history of research has revealed sex differences in numerous components of the HPA stress system and its responses, which may partially form the basis for sex disparities in disease development. Despite this, many studies use male subjects exclusively, while fewer reports involve females or provide direct sex comparisons. The purpose of this article is to present sex comparisons in the functional and molecular aspects of the HPA axis, through various phases of activity, including basal, acute stress, and chronic stress conditions. The HPA axis in females…

A consensus endocrine profile for chronically stressed wild animals does not exist.
Given the connection between chronic stress and health, there has been a growing emphasis on identifying chronically stressed wild animals, especially in relation to anthropogenic disturbances. There is considerable confusion, however, in how to identify chronically stressed wild animals, but the most common assumption is that measures of glucocorticoid (GC) function will increase. In an attempt to determine an "endocrine profile" of a chronically stressed wild animal, this review collected papers from the literature that measured baseline GC, stress-induced GC, measures of integrated GC, negative feedback, hypothalamic-pituitary-adrenal axis sensitivity, and/or body weight in chronically stressed animals. The collected studies encompassed laboratory and field studies, numerous diverse species, and multiple techniques for inducing chronic stress. Each paper was ranked according to its re…

Interpreting stress responses during routine toxicity studies: a review of the biology, impact, and assessment.
Stress often occurs during toxicity studies. The perception of sensory stimuli as stressful primarily results in catecholamine release and activation of the hypothalamic-pituitary-adrenal (HPA) axis to increase serum glucocorticoid concentrations. Downstream effects of these neuroendocrine signals may include decreased total body weights or body weight gain; food consumption and activity; altered organ weights (e.g., thymus, spleen, adrenal); lymphocyte depletion in thymus and spleen; altered circulating leukocyte counts (e.g., increased neutrophils with decreased lymphocytes and eosinophils); and altered reproductive functions. Typically, only some of these findings occur in a given study. Stress responses should be interpreted as secondary (indirect) rather than primary (direct) test article-related findings. Determining whether effects are the result of stress requires a weight-of-evi…

Metabolic consequences of stress during childhood and adolescence.
Stress, that is, the state of threatened or perceived as threatened homeostasis, is associated with activation of the stress system, mainly comprised by the hypothalamic-pituitary-adrenal axis and the arousal/sympathetic nervous systems. The stress system normally functions in a circadian manner and interacts with other systems to regulate a variety of behavioral, endocrine, metabolic, immune, and cardiovascular functions. However, the experience of acute intense physical or emotional stress, as well as of chronic stress, may lead to the development of or may exacerbate several psychologic and somatic conditions, including anxiety disorders, depression, obesity, and the metabolic syndrome. In chronically stressed individuals, both behavioral and neuroendocrine mechanisms promote obesity and metabolic abnormalities: unhealthy lifestyles in conjunction with dysregulation of the stress syst…

Cortisol and finfish welfare.
Previous reviews of stress, and the stress hormone cortisol, in fish have focussed on physiology, due to interest in impacts on aquaculture production. Here, we discuss cortisol in relation to fish welfare. Cortisol is a readily measured component of the primary (neuroendocrine) stress response and is relevant to fish welfare as it affects physiological and brain functions and modifies behaviour. However, we argue that cortisol has little value if welfare is viewed purely from a functional (or behavioural) perspective-the cortisol response itself is a natural, adaptive response and is not predictive of coping as downstream impacts on function and behaviour are dose-, time- and context-dependent and not predictable. Nevertheless, we argue that welfare should be considered in terms of mental health and feelings, and that stress in relation to welfare should be viewed as psychological, rath…

Human models in acute and chronic stress: assessing determinants of individual hypothalamus-pituitary-adrenal axis activity and reactivity.
Stress is one of the most significant health problems in modern societies and the 21st century. This explains a pressing need for investigations into the biological pathways linking stress and health. Besides the locus coeruleus-noradrenaline/autonomic (sympathetic) nervous system ( Chrousos and Gold 1992 ), the hypothalamus-pituitary-adrenal (HPA) axis is the major physiological stress response system in the body. Since alterations in HPA axis regulation under basal conditions and in response to acute stress appear to be a close correlate or even a determining factor of the onset of different diseases or disease progression ( Holsboer 1989 ; Chrousos and Gold 1992 ; Tsigos and Chrousos 1994, 2002 ; Stratakis and Chrousos 1995 ; McEwen 1998 ; Heim et al. 2000a ; Raison and Miller 2003 ), the characterization of an individual's HPA axis activity as well as reactivity pattern to psychosoci…

An assessment of cortisol analysis in hair and its clinical applications.
Hair analyses for exogenous compounds, specifically drugs of abuse, have been a useful tool in detecting long-term drug exposure. More recently, studies have delved into the exposure of endogenous compounds in hair. Cortisol is synthesized in the adrenal cortex in response to stress-induced activation of the hypothalamic-pituitary-adrenal (HPA) axis. While catecholamines generally indicate acute stress, cortisol can be used as an indicator for sub-acute and chronic stress. Studies on the effects of chronic stress are most often subjective in nature, relying on questionnaires asking the participant to recall on past stressors. This can lead to the issue of recall and reporting bias. A new objective measure of chronic stress is needed for a more accurate understanding of the effects of chronic stress on the body. This review uses emerging evidence to describe the usefulness of hair analysi…

Endocannabinoid-mediated modulation of stress responses: physiological and pathophysiological significance.
The stress response is associated with a broad spectrum of physiological and behavioural effects including hypothalamo-pituitary-adrenal (HPA) axis activation, altered central nervous system activity, neuroimmune alterations, anxiety- and depressive-like behaviour and analgesia. While the acute stress response has essential survival value, chronic stress and dysfunction of the stress response can be maladaptive, contributing to the development and severity of psychiatric and pain disorders. The endogenous cannabinoid (endocannabinoid) system has emerged as an important lipid signalling system playing a key role in mediating and/or modulating behavioural, neurochemical, neuroendocrine, neuroimmune and molecular responses to stress. The weight of evidence, reviewed here, points largely to a system which serves to constrain HPA axis activity, facilitate adaptation or habituation of HPA axis…

Why do we respond so differently? Reviewing determinants of human salivary cortisol responses to challenge.
Stress and stress-related health impairments are major problems in human life and elucidating the biological pathways linking stress and disease is of substantial importance. However, the identification of mechanisms underlying a dysregulation of major components of the stress response system is, particularly in humans, a very challenging task. Salivary cortisol responses to diverse acute challenge paradigms show large intra- and interindividual variability. In order to uncover mechanisms mediating stress-related disorders and to potentially develop new therapeutic strategies, an extensive phenotyping of HPA axis stress responses is essential. Such a research agenda depends on substantial knowledge of moderating and intervening variables that affect cortisol responses to different stressors and stimuli. The aim of this report is, therefore, to provide a comprehensive summary of important…

Shaping the stress response: interplay of palatable food choices, glucocorticoids, insulin and abdominal obesity.
Activity of the hypothalamo-pituitary-adrenal (HPA) axis is regulated by a negative feedback loop that dampens central drive of the axis via the actions of the secreted glucocorticoids. Conversely, under conditions of chronic stress, glucocorticoids delivered centrally increase hypothalamic paraventricular nucleus (PVN) corticotrophin-releasing factor (CRF) expression and the response to restraint. However, HPA axis activity and PVN CRF mRNA expression under chronic stress conditions are often reduced, implying other indirect peripheral or extra-hypothalamic glucocorticoid actions. Glucocorticoids chronically increase palatable food intake, which increases abdominal fat depots and circulating insulin levels, both of which negatively correlate with PVN CRF mRNA expression and may in turn dampen the response to stress. Such an effect is dependent on food choices, rather than total calories…

Chronic stress, drug use, and vulnerability to addiction.
Stress is a well-known risk factor in the development of addiction and in addiction relapse vulnerability. A series of population-based and epidemiological studies have identified specific stressors and individual-level variables that are predictive of substance use and abuse. Preclinical research also shows that stress exposure enhances drug self-administration and reinstates drug seeking in drug-experienced animals. The deleterious effects of early life stress, child maltreatment, and accumulated adversity on alterations in the corticotropin releasing factor and hypothalamic-pituitary-adrenal axis (CRF/HPA), the extrahypothalamic CRF, the autonomic arousal, and the central noradrenergic systems are also presented. The effects of these alterations on the corticostriatal-limbic motivational, learning, and adaptation systems that include mesolimbic dopamine, glutamate, and gamma-amino-but…

Pathophysiological mechanisms of stress-induced intestinal damage.
Stress has been shown to have both central and peripheral effects, promoting psychological illness (such as anxiety and depression), as well influencing peripheral disease in the intestine. Stress in humans can exacerbate symptoms of irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD), lowering visceral pain thresholds and decreasing mucosal barrier function. Studies in rodents have revealed that both acute and chronic exposure to stressors can lead to pathophysiology of the small and large intestine, including altered ion secretion and increased epithelial permeability (by both transcellular and paracellular pathways). Prolonged exposure to stress can induce low-grade inflammation, cause ultrastructural epithelial abnormalities, and alter bacterial-host interactions allowing greater microbial translocation. In this review, we discuss the stress response and the effects o…

Stress, depression, and neuroplasticity: a convergence of mechanisms.
Increasing evidence demonstrates that neuroplasticity, a fundamental mechanism of neuronal adaptation, is disrupted in mood disorders and in animal models of stress. Here we provide an overview of the evidence that chronic stress, which can precipitate or exacerbate depression, disrupts neuroplasticity, while antidepressant treatment produces opposing effects and can enhance neuroplasticity. We discuss neuroplasticity at different levels: structural plasticity (such as plastic changes in spine and dendrite morphology as well as adult neurogenesis), functional synaptic plasticity, and the molecular and cellular mechanisms accompanying such changes. Together, these studies elucidate mechanisms that may contribute to the pathophysiology of depression. Greater appreciation of the convergence of mechanisms between stress, depression, and neuroplasticity is likely to lead to the identification…

Stress, eating and the reward system.
An increasing number of people report concerns about the amount of stress in their life. At the same time obesity is an escalating health problem worldwide. Evidence is accumulating rapidly that stress related chronic stimulation of the hypothalamic-pituitary-adrenal (HPA) axis and resulting excess glucocorticoid exposure may play a potential role in the development of visceral obesity. Since adequate regulation of energy and food intake under stress is important for survival, it is not surprising that the HPA axis is not only the 'conductor' of an appropriate stress response, but is also tightly intertwined with the endocrine regulation of appetite. Here we attempt to link animal and human literatures to tease apart how different types of psychological stress affect eating. We propose a theoretical model of Reward Based Stress Eating. This model emphasizes the role of cortisol and rewar…

CRF and stress in fish.
The endocrine stress response is pivotal in vertebrate physiology. The stress hormone cortisol-the end product of the endocrine stress axis-(re-)directs energy flows for optimal performance under conditions where homeostasis may be or become at risk. Key players in the continuous adaptation process are corticotropin-releasing factor (CRF) from the hypothalamic nucleus preopticus (NPO), pituitary adrenocorticotropic hormone (ACTH) and cortisol produced by the interrenal cells in the headkidney (adrenal equivalent of fish). CRF is a member of a large family of related peptides that signals through CRF-receptor subtypes specific for central and peripheral actions of the peptide. CRF is "chaperoned" by a unique and phylogenetically very well-conserved binding protein (CRFBP); the functions of the CRFBP can only be speculated on so far, but its mRNA and protein abundance are important indicat…

Stress, visceral obesity, and metabolic complications.
Stress is a state of threatened homeostasis or disharmony caused by intrinsic or extrinsic adverse forces and is counteracted by an intricate repertoire of physiologic and behavioral responses that aim to reestablish the challenged body equilibrium. The adaptive stress response depends upon an elaborate neuroendocrine, cellular, and molecular infrastructure, the stress system. Crucial functions of the stress system response are mediated by the hypothalamic-pituitary-adrenal (HPA) axis and the central and peripheral components of the autonomic nervous system (ANS). The integrity of the HPA axis and the ANS and their precise interactions with other CNS components are essential for a successful response to the various stressors. Chronic stress represents a prolonged threat to homeostasis by persistent or frequently repeated stressors and may lead to manifestations that characterize a wide r…

Dysregulated physiological stress systems and accelerated cellular aging.
Exposure to chronic stressors is associated with accelerated biological aging as indicated by reduced leukocyte telomere length (LTL). This impact could be because of chronic overactivation of the body's physiological stress systems. This study examined the associations between LTL and the immune system, hypothalamic-pituitary-adrenal axis and autonomic nervous system. LTL was assessed in 2936 adults from the Netherlands Study of Depression and Anxiety. Inflammation markers (interleukin-6, c-reactive protein, tumor necrosis factor-alpha), hypothalamic-pituitary-adrenal-axis indicators (salivary cortisol awakening curve [area under the curve indicators, with respect to the ground and increase], evening levels, 0.5 mg dexamethasone cortisol suppression ratio), and autonomic nervous system measures (heart rate, respiratory sinus arrhythmia, pre-ejection period) were determined. Linear regre…

Prevalence of and factors associated with sarcopenia in elderly patients with end-stage renal disease.
Background & aims: We investigated the prevalence of sarcopenia in elderly patients with end-stage renal disease (ESRD) and its relationship with various markers of nutrition, cognitive function, depressive symptoms, inflammation and β2-microglobulin. Methods: A cross-sectional study was conducted with 95 patients having ESRD aged over 50 years. Sarcopenia was defined as a decline in both muscle mass and strength. Results: The mean age was 63.9 ± 10.0 years; 56.8% were men and 52.6% had diabetes. Sarcopenia was highly prevalent in elderly patients with ESRD (37.0% in men and 29.3% in women). Subjective Global Assessment (SGA), inflammatory markers and β2-microglobulin levels were significantly associated with sarcopenia, even after adjustment for age, gender, diabetes, and body mass index. Additionally, patients with depressive symptoms showed a higher risk of sarcopenia relative to thos…

Chronic inflammation in end-stage renal disease and dialysis.
Under normal conditions, inflammation is a protective and physiological response to various harmful stimuli. However, in several chronic debilitating disorders, such as chronic kidney disease, inflammation becomes maladaptive, uncontrolled and persistent. Systemic persistent inflammation has, for almost 20 years, been recognized as a major contributor to the uraemic phenotype (such as cardiovascular disease, protein energy wasting, depression, osteoporosis and frailty), and a predictor of cardiovascular and total mortality. Since inflammation is mechanistically related to several ageing processes (inflammageing), it may be a major driver of a progeric phenotype in the uraemic milieu. Inflammation is likely the consequence of a multifactorial aetiology and interacts with a number of factors that emerge when uraemic toxins accumulate. Beside interventions aiming to decrease the production …

So! What's aging? Is cardiovascular aging a disease?
"Inside every old person is a young person wondering what happened." So, what is aging? Aging is a manifestation of progressive, time-dependent failure of molecular mechanisms that create disorder within a system of DNA and its environment (nuclear, cytosolic, tissue, organ, organism, other organisms, society, terra firma, atmosphere, universe). Continuous signaling, transmitted with different kinetics across each of these environments, confers a "mutual enslavement" that creates ordered functions among the components within the system. Accrual of this molecular disorder over time, i.e. during aging, causes progressive changes in the structure and function of the heart and arteries that are quite similar in humans, non-human primates, rabbits and rats that compromise cardiovascular reserve function, and confer a marked risk for incident cardiovascular disease. Nearly all aspects of signa…

Stress habituation, body shape and cardiovascular mortality.
High cardiovascular mortality is well documented in lean phenotypes exhibiting visceral fat accumulation. In contrast, corpulent phenotypes with predominantly subcutaneous fat accumulation display a surprisingly low mortality. The term 'obesity paradox' reflects the difficulty in understanding the biological mechanisms underlying these clinical observations. The allostatic load model of chronic stress focuses on glucocorticoid dysregulation as part of a 'network of allostasis' involving autonomic, endocrine, metabolic, and immune mediators. Here, we expand upon the energetic demands of the brain and show that 'habituators' and 'non-habituators' develop divergent patterns of fat distribution. Central to this process is the recurrent rise in the cerebral energy need (arousal) that non-habituators experience during chronic stress. These neuroenergetic alterations promote visceral fat accumu…

Beyond heart rate variability: vagal regulation of allostatic systems.
The autonomic nervous system (ANS) plays a role in a wide range of somatic and mental diseases. Whereas the role of the ANS in the regulation of the cardiovascular system seems evident, its role in the regulation of other systems associated with allostasis is less clear. Using a model of neurovisceral integration we describe how the ANS and parasympathetic tone in particular may be associated with the regulation of allostatic systems associated with glucose regulation, hypothalamic-pituitary-adrenal (HPA) axis function, and inflammatory processes. Decreased vagal function and heart rate variability (HRV) were shown to be associated with increased fasting glucose and hemoglobin A1c levels, increased overnight urinary cortisol, and increased proinflammatory cytokines and acute-phase proteins. All of these factors have been associated with increased allostatic load and poor health. Thus, va…

Comparisons of ultrafine and fine particles in their associations with biomarkers reflecting physiological pathways.
Using a quasi-experimental opportunity offered by greatly restricted air pollution emissions during the Beijing Olympics compared to before and after the Olympics, we conducted the current study to compare ultrafine particles (UFPs) and fine particles (PM2.5) in their associations with biomarkers reflecting multiple pathophysiological pathways linking exposure and cardiorespiratory events. Number concentrations of particles (13.0-764.7 nm) and mass concentrations of PM2.5 were measured at two locations within 9 km from the residence and workplace of 125 participating Beijing residents. Each participant was measured 6 times for biomarkers of autonomic function (heart rate, systolic and diastolic blood pressures), hemostasis (von Willebrand factor, soluble CD40 ligand, and P-selectin), pulmonary inflammation and oxidative stress (exhaled nitric oxide and exhaled breath condensate pH, malon…
