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

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

The influences of vitamin D and omega-3 co-supplementation on clinical, metabolic and genetic parameters in women with polycystic ovary syndrome.: Objective: The aim of this study was to evaluate the effect of the co-administration of vitamin D and omega-3 fatty acid on clinical, metabolic and genetic parameters in women with polycystic ovary syndrome (PCOS). Methods: This randomized, double-blinded, placebo-controlled clinical trial was conducted on 60 subjects, aged 18-40 years old with PCOS. Subjects were randomly allocated to take either 50,000 IU vitamin D every 2 weeks plus 2000 mg/day omega-3 fatty acid from fish oil (n = 30) or pla

The effect of Nigella sativa (black seed) on biomarkers of inflammation and oxidative stress: an updated systematic review and meta-analysis of randomized controlled trials.: Objective: This study was conducted to assess the effect of Nigella sativa (N. sativa) supplementation on inflammatory and oxidative markers among the adult population. Methods: We carried out a comprehensive, systematic search of Scopus, Embase, Cochrane Library, Web of Science, PubMed, and Google Scholar till December 2022. A random-effects model was used to estimate the overall effect size. Results: In total, twenty trials consisting of 1086 participants were included in the meta-analysis. Fi

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. For over 30 years, an extensive body of research has drawn on the AL framework but has been hampered by the lack of a consistent definition. Methods: This study analyses data for 67,126 individuals aged 40-111 years participating in 13 different cohort studies and 40 biomarkers across 12 physiological systems: hypothalamic-pituitary-adrenal (HPA) axis, s

Cytokines and C-reactive protein alterations with respect to cognitive impairment in schizophrenia and bipolar disorder: A systematic review.: Background: The aim of this article was to perform a systematic review of studies investigating the association between peripheral levels of cytokines and C-reactive protein (CRP), cytokine gene polymorphisms and cognition in patients with schizophrenia and bipolar disorder (BD). Methods: The following databases: PubMed, CINAHL Complete, Academic Search Complete, ERIC and Health Source: Nursing/Academic Edition databases were searched according to the PRISMA guidelines. We included studies that

The effect of Ramadan intermittent fasting on anthropometric, hormonal, metabolic, inflammatory, and oxidative stress markers in pre-and post-menopausal women: a prospective cohort of Saudi women.

Background: The menopausal transition significantly affects cardiometabolic health, primarily due to changes in reproductive hormones, particularly decreased estrogen levels and relative androgen excess. Adult Muslim women, both pre-and post-menopausal, are mandated to observe Ramadan intermittent fasting (RIF) every year. Therefore, the current study was designed to investigate RIF's effects on pre-menopausal (PRE-M) and post-menopausal (POST-M) healthy women's cardiometabolic health markers. This study further evaluated the relationship between tested markers and the participant's basic variables, such as BMI and body fatness. Due to differences in physiological and metabolic biomarkers between groups, RIF is likely to impact PRE-M and POST-M women differently. Methods: This study included 62 healthy women (31 PRE-M, aged 21-42 years, and 31 POST-M, aged 43-68 years) who observed RIF. …

Psychosocial predictors of the innate immune response to influenza vaccination.

Experimental activation of the innate immune system has contributed significantly to both our understanding of how psychological factors influence immune function as well as how immune activity influences the brain and behavior. The annual influenza vaccine can be used to interrogate the effects of mild immune stimulation on day-to-day changes in psychological processes in human subjects that range across the lifespan and in both clinical and non-clinical populations. Yet, the immune response to the influenza vaccine in the days immediately following its administration are not well characterized. The present study describes changes in inflammatory and antiviral gene expression within circulating immune cells, plasma cytokines, and C-reactive protein (CRP) following receipt of the flu vaccine, and further reports the association between several common behavioral health factors and the acu…

Microglia activation in the presence of intact blood-brain barrier and disruption of hippocampal neurogenesis via IL-6 and IL-18 mediate early diffuse neuropsychiatric lupus.

Introduction: Inflammatory mediators are detected in the cerebrospinal fluid of systemic lupus erythematosus patients with central nervous system involvement (NPSLE), yet the underlying cellular and molecular mechanisms leading to neuropsychiatric disease remain elusive. Methods: We performed a comprehensive phenotyping of NZB/W-F1 lupus-prone mice including tests for depression, anxiety and cognition. Immunofluorescence, flow cytometry, RNA-sequencing, qPCR, cytokine quantification and blood-brain barrier (BBB) permeability assays were applied in hippocampal tissue obtained in both prenephritic (3-month-old) and nephritic (6-month-old) lupus mice and matched control strains. Healthy adult hippocampal neural stem cells (hiNSCs) were exposed ex vivo to exogenous inflammatory cytokines to assess their effects on proliferation and apoptosis. Results: At the prenephritic stage, BBB is intact…

The relationship between immune fitness and saliva biomarkers of systemic inflammation.

Purpose: It is vital that Immune fitness, i.e., how well the immune system functions and reacts to challenges, can be reliably be examined. The current study aimed to compare immune fitness with assessments of saliva biomarkers of systemic inflammation. Methods: N = 108 healthy young adults (18-30-year-old students of Utrecht University, the Netherlands) participated in the study. A saliva sample was collected for biomarker assessment (Interleukin (IL)-1β, IL-6, IL-8, IL-10, immunoglobulin A (IgA), and tumor necrosis factor-alpha (TNF-α), and c-reactive protein (CRP). Additionally, a survey was completed to assess immune fitness, mood, mental resilience, and quality of life. The correlations between the biomarker assessments, immune fitness and mood were determined. Results: No significant correlations between immune fitness and biomarkers of systemic inflammation were found. Significant…

Lactobacillus fermentum HNU312 alleviated oxidative damage and behavioural abnormalities during brain development in early life induced by chronic lead exposure.

Lead exposure is a global public health safety issue that severely disrupts brain development and causes damage to the nervous system in early life. Probiotics and gut microbes have been highlighted for their critical roles in mitigating lead toxicity. However, the underlying mechanisms by which they work yet to be fully explored. Here, we designed a two-stage experiment using the probiotic Lactobacillus fermentum HNU312 (Lf312) to uncover how probiotics alleviate lead toxicity to the brain during early life. First, we explored the tolerance and adsorption of Lf312 to lead in vitro. Second, the adsorption capacity of the strain was determined and confirmed in vivo. The shotgun metagenome sequencing showed lead exposure-induced imbalance and dysfunction of the gut microbiome. In contrast, Lf312 intake significantly modulated the structure of the microbiome, increased the abundance of bene…

Mitigation of honokiol on fluoride-induced mitochondrial oxidative stress, mitochondrial dysfunction, and cognitive deficits through activating AMPK/PGC-1α/Sirt3.

Oxidative stress and mitochondrial dysfunction contribute greatly to fluoride-induced cognitive impairment and behavioural disorders. Honokiol, a natural biphenolic compound, possesses antioxidant and mitochondrial protective properties. The present study investigated the protective actions of honokiol on NaF-elicited cognitive deficits and elucidated the possible mechanism of honokiol-mediated protection. The results demonstrated that honokiol administration markedly attenuated fluoride-induced cognitive impairments and neural/synaptic injury in mice. Moreover, honokiol elevated the activity and expression of SOD2 and promoted mtROS scavenging through Sirt3 activation in NaF-treated mice and SH-SY5Y cell lines. Meanwhile, honokiol substantially lowered mtROS production by enhancing Sirt3-mediated mitochondrial DNA (mtDNA) transcription, thereby leading to significant increases in ATP sy…

Intermittent hypoxia is involved in gut microbial dysbiosis in type 2 diabetes mellitus and obstructive sleep apnea-hypopnea syndrome.

Background: Obstructive sleep apnea (OSA)-hypopnea syndrome (OSAHS) has been recognized as a comorbidity of type 2 diabetes mellitus (T2DM); more than half of T2DM patients suffer from OSAHS. Intermittent hypoxia (IH) plays an important role in metabolic diseases, such as obesity and OSAHS, through various mechanisms, including altering the gut microecological composition and function. Therefore, it is important to study the role of gut microbiota in T2DM patients with OSAHS, which has a high incidence and is prone to several complications. Aim: To assess whether IH is involved in altering the fecal microbiome in T2DM patients with OSAHS. Methods: Seventy-eight participants were enrolled from Henan Province People's Hospital and divided into healthy control (HC, n = 26), T2DM (n = 25), and T2DM + OSA (n = 27) groups based on their conditions. The fecal bacterial DNA of the research parti…

Diminished Cellular Immunity and Executive Cognitive Functioning Among Middle-Aged and Elderly Adults.

Objective: Within the field of psychoneuroimmunology, much attention has been given to immune dysregulation and its impact on cognitive functioning. Some of this work has focused on the association between high levels of basal proinflammatory cytokines and poorer performance on measures of executive functioning; however, effect sizes have been quite small in human studies. Methods: We investigated whether Epstein-Barr virus (EBV) antibody titers, a marker of immune dysregulation related to cellular immunity, may be associated with executive functioning while also attempting to replicate prior studies using two markers of proinflammatory cytokine production (i.e., circulating and lipopolysaccharide [LPS]-stimulated cytokines [interleukin 6, interleukin 1β, interferon-γ]). A total of 71 community-dwelling adults (mean [standard deviation] age = 60.87 [6.26] years) who were seropositive for…

Protective effects of black seed (Nigella sativa) diet supplementation in common carp (Cyprinus carpio) against immune depression, oxidative stress and metabolism dysfunction induced by glyphosate.

Sustainable aquaculture arises as key to increase food production in the coming years. However, the sector still faces many challenges such as the exposure of the cultured animals to pesticide-contaminated water. Pesticides used in agriculture can reach aquaculture systems either directly (integrated-agriculture aquaculture practices) or indirectly (soil leakage) and cause a broad range of ecotoxicological effects on cultured fish and shellfish. Here, we studied how glyphosate affects several haematological, biochemical, and immune parameters in common carp (Cyprinus carpio) fingerlings, the fourth most important cultured fish species worldwide. We also evaluated the potential of dietary supplementation with black seed (Nigella sativa, 0.25, 0.5 and 1%) to lower glyphosate-associated toxicity. Our results showed that 14-day sub-lethal exposure of common carp fingerlings to glyphosate inc…

Endocrine and immunomodulatory effects of social isolation and loneliness across adulthood.

Experimental and observational evidence agreed on two interconnected biological mechanisms responsible for the links between social isolation/loneliness and health: alterations in the activity of the hypothalamic-pituitary-adrenal (HPA) axis and compromised functioning of the innate immune system. However, most existing studies did not consider the simultaneous impact of social isolation and loneliness on biological outcomes. Further, they only assessed one biological outcome at a time and did not test any moderation by age, despite empirical and theoretical evidence supporting the plausibility of this hypothesis. To address these gaps in the literature, we tested the associations between two indicators of social isolation (living status and frequency of social contacts) and loneliness and daily cortisol secretion and two markers of systemic inflammation (C-reactive protein [CRP] and int…

Western Dietary Pattern Antioxidant Intakes and Oxidative Stress: Importance During the SARS-CoV-2/COVID-19 Pandemic.

The importance of balanced dietary habits, which include appropriate amounts of antioxidants to maintain the immune system, has become increasingly relevant during the current SARS-CoV-2/COVID-19 pandemic, because viral infections are characterized by high oxidative stress. Furthermore, the measures taken by governments to control the pandemic have led to increased anxiety, stress, and depression, which affect physical and mental health, all of which are influenced by nutritional status, diet, and lifestyle. The Mediterranean diet (MD), Atlantic diet (AD), and the Dietary Guidelines for Americans all provide the essential vitamins, minerals, and phenolic compounds needed to activate enzymatic and nonenzymatic antioxidant responses. However, viral pandemics such as the current COVID-19 crisis entail high oxidative damage caused by both the infection and the resultant social stresses withi…

Exploring pharmacological approaches for managing cytokine storm associated with pneumonia and acute respiratory distress syndrome in COVID-19 patients.

Sars-CoV-2 complications include pneumonia and acute respiratory distress syndrome (ARDS), which require intensive care unit admission. These conditions have rapidly overwhelmed healthcare systems, with detrimental effects on the quality of care and increased mortality. Social isolation strategies have been implemented worldwide with the aim of reducing hospital pressure. Among therapeutic strategies, the use of immunomodulating drugs, to improve prognosis, seems promising. Particularly, since pneumonia and ARDS are associated with a cytokine storm, drugs belonging to therapeutic classes as anti-IL-6, anti-TNF, and JAK inhibitors are currently studied. In this article, we discuss the potential advantages of the most promising pharmacological approaches.

Effect of Clostridium butyricum against Microglia-Mediated Neuroinflammation in Alzheimer's Disease via Regulating Gut Microbiota and Metabolites Butyrate.

Scope: Recent evidences demonstrate that abnormal gut microbiota (GM) might be involved in the pathogenesis of Alzheimer's disease (AD). However, the role of probiotics in preventing AD by regulating GM-gut-brain axis remains unclear. Here, the anti-neuroinflammatory effect and its mechanism of probiotic Clostridium butyricum (CB) against AD is investigated by regulating GM-gut-brain axis. Methods and results: APPswe/PS1dE9 (APP/PS1) transgenic are treated intragastrically with CB for 4 weeks then cognitively tested. Amyloid-β (Aβ) burden, microglial activation, proinflammatory cytokines production, GM, and metabolites butyrate are analyzed. Moreover, Aβ-induced BV2 microglia are pretreated with butyrate, and the levels of cluster of differentiation 11b (CD11b), cyclooxygenase-2 (COX-2), and NF-κB p65 phosphorylation are determined. The results show that CB treatment prevents cognitive i…

Nicotinamide riboside alleviates alcohol-induced depression-like behaviours in C57BL/6J mice by altering the intestinal microbiota associated with microglial activation and BDNF expression.

The gut microbiota play an important role in many central nervous system diseases through the gut microbiota-brain axis. Recent studies suggest that nicotinamide riboside (NR) has neuroprotective properties. However, it is unknown whether NR can prevent or protect against alcohol-induced depression. Furthermore, it is unclear whether its therapeutic action involves changes in the composition of the gut microbiome. Here, we investigated the effects of NR in the mouse model of alcohol-induced depression. Treatment with NR improved the alcohol-induced depressive behaviour in mice. In addition, NR decreased the number of activated microglia in the hippocampus, and it reduced the levels of pro-inflammatory (IL-1β, IL-6, and TNF-α) and anti-inflammatory (IL-10 and TGF-β) cytokines in the brain of mice with alcohol-induced depression. Furthermore, NR significantly upregulated BDNF and diminishe…

Multi-omics Analysis of the Intermittent Fasting Response in Mice Identifies an Unexpected Role for HNF4α.

Every-other-day fasting (EODF) is an effective intervention for the treatment of metabolic disease, including improvements in liver health. But how the liver proteome is reprogrammed by EODF is currently unknown. Here, we use EODF in mice and multi-omics analysis to identify regulated pathways. Many changes in the liver proteome are distinct after EODF and absent after a single fasting bout. Key among these is the simultaneous induction by EODF of de novo lipogenesis and fatty acid oxidation enzymes. Together with activation of oxidative stress defenses, this contributes to the improvements in glucose tolerance and lifespan after EODF. Enrichment analysis shows unexpected downregulation of HNF4α targets by EODF, and we confirm HNF4α inhibition. Suppressed HNF4α targets include bile synthetic enzymes and secreted proteins, such as α1-antitrypsin or inflammatory factors, which reflect EODF…

Ellagic acid protects mice against sleep deprivation-induced memory impairment and anxiety by inhibiting TLR4 and activating Nrf2.

Sleep disorder has become a prevalent issue in current society and is connected with the deterioration of neurobehaviors such as mood, cognition and memory. Ellagic acid (EA) is a phenolic phytoconstituent extracted from grains and fruits that has potent neuroprotective properties. This research aimed to study the alleviative effect and mechanism of EA on memory impairment and anxiety caused by sleep deprivation (SD). EA ameliorated behavioral abnormalities in SD mice, associated with increased dendritic spine density, and reduced shrinkage and loss of hippocampal neurons. EA reduced the inflammatory response and oxidative stress injury caused by SD, which may be related to activation of the Nrf2/HO-1 pathway and mitigation of the TLR4-induced inflammatory response. In addition, EA significantly reduced the mortality and ROS levels in glutamate (Glu)-induced hippocampal neuron injury, an…

Associations between hardiness, C-reactive protein, and telomere length among former prisoners of war.

Background: War captivity and posttraumatic stress disorder (PTSD) are known to be associated with several poor health outcomes of an accelerated aging process. However, the contribution of personality protective factors to this phenomenon are rarely studied. The present 24-year prospective study examined associations between psychological hardiness and three health outcomes: C-reactive protein (CRP) levels, metabolic syndrome (MetS), and telomere length (TL). Method: Eighty-eight Israeli former prisoners of war (ex-POWs) were assessed 18 (T1) and 42 (T2) years after repatriation. Data on hardiness was collected at T1 while leukocyte TL, CRP, and MetS data was collected 42 years after the war. Results: While adjusting for age, body mass index (BMI), self-rated health, depressive and PTSD symptoms at T2, higher levels of hardiness at T1 predicted decreased CRP and longer TL at T2. Conclus…

Heat and dehydration induced oxidative damage and antioxidant defenses following incubator heat stress and a simulated heat wave in wild caught four-striped field mice Rhabdomys dilectus.

Heat waves are known for their disastrous mass die-off effects due to dehydration and cell damage, but little is known about the non-lethal consequences of surviving severe heat exposure. Severe heat exposure can cause oxidative stress which can have negative consequences on animal cognition, reproduction and life expectancy. We investigated the current oxidative stress experienced by a mesic mouse species, the four striped field mouse, Rhabdomys dilectus through a heat wave simulation with ad lib water and a more severe temperature exposure with minimal water. Wild four striped field mice were caught between 2017 and 2019. We predicted that wild four striped field mice in the heat wave simulation would show less susceptibility to oxidative stress as compared to a more severe heat stress which is likely to occur in the future. Oxidative stress was determined in the liver, kidney and brai…

Telomere Length Dynamics and DNA Damage Responses Associated with Long-Duration Spaceflight.

Telomere length dynamics and DNA damage responses were assessed before, during, and after one-year or shorter duration missions aboard the International Space Station (ISS) in a comparatively large cohort of astronauts (n = 11). Although generally healthy individuals, astronauts tended to have significantly shorter telomeres and lower telomerase activity than age- and sex-matched ground controls before and after spaceflight. Although telomeres were longer during spaceflight irrespective of mission duration, telomere length shortened rapidly upon return to Earth, and overall astronauts had shorter telomeres after spaceflight than they did before; inter-individual differences were identified. During spaceflight, all crewmembers experienced oxidative stress, which positively correlated with telomere length dynamics. Significantly increased frequencies of chromosomal inversions were observed…

Inhibition of PRMT5 Attenuates Oxidative Stress-Induced Pyroptosis via Activation of the Nrf2/HO-1 Signal Pathway in a Mouse Model of Renal Ischemia-Reperfusion Injury.

Background: Extensive evidence has demonstrated that oxidative stress, pyroptosis, and proinflammatory programmed cell death are related to renal ischemia/reperfusion (I/R) injury. However, the underlying mechanism remains to be illustrated. Protein arginine methylation transferase 5 (PRMT5), which mediates arginine methylation involved in the regulation of epigenetics, exhibits a variety of biological functions and essential roles in diseases. The present study investigated the role of PRMT5 in oxidative stress and pyroptosis induced by I/R injury in a mouse model and in a hypoxia/reoxygenation (H/R) model of HK-2 cells. Methods: C57 mice were used as an animal model. All mice underwent right nephrectomy, and the left renal pedicles were either clamped or not. Renal I/R injury was induced by ligating the left renal pedicle for 30 min followed by reperfusion for 24 h. HK-2 cells were exp…

Oxidant and antioxidant parameters in people who fast during Ramadan, and those who do not.

Background: Objectives: The main aim of this study was to compare, by a new automated colorimetric method, oxidant and anti-oxidant status of those who fast during Ramadan and those who do not. For this purpose, total oxidant status (TOS), total anti-oxidant capacity (TAC) levels and oxidative stress index (OSI) were analysed. By doing this, we hope to examine whether fasting has any beneficial effect on human health. Materials and methods: Fifty seven people were included in this study. Of these, 30 people had been fasting during the month of Ramadan for at least ten years, but 27 had never fasted in their life. On the 15th day of Ramadan, blood samples were obtained from both groups after 12 hours of fasting. Results: The TAC levels of the fasting group (1.29±0,19) was quite higher than the non-fasting group (1,09±0,16) [EIC2][ICD3] [ICD4](p< 0.001). Similarly, in the fasting group TOS…

Secondhand Smoke Exposure and Sleep-Related Breathing Problems in Toddlers.

Background: Adequate sleep during childhood is an important component of overall health and wellbeing for children. Secondhand smoke (SHS) exposure has been linked to a greater risk of sleep-disordered breathing. Objective: Our objective was to investigate relationships between SHS exposure and sleep-related breathing problems in healthy toddlers aged 2 to 5 years. We hypothesized that there is an independent relationship between objectively measured SHS exposure and presence of sleep-related breathing problems by parental report. Methods: A convenience sample of 149 healthy children ages 2 to 5 years was recruited from an academic pediatric primary care center for this cross-sectional study; 138 had complete data that were analyzed. Current SHS exposure was determined by hair nicotine level. Presence of sleep-related breathing problems was assessed by 1 survey item. Inflammation was det…

Mapping of γ/δ T cells reveals Vδ2+ T cells resistance to senescence.

Background: Immune adaptation with aging is a major of health outcomes. Studies in humans have mainly focus on αβ T cells while γδ T cells have been neglected despite their role in immunosurveillance. We investigated the impact of aging on γδ T cell subsets phenotypes, functions, senescence and their molecular response to stress. Methods: Peripheral blood of young and old donors in Singapore have been used to assess the phenotype, functional capacity, proliferation capacity and gene expression of the various γδ T cell subsets. Peripheral blood mononuclear cells from apheresis cones and young donors have been used to characterize the telomere length, epigenetics profile and DNA damage response of the various γδ T cell subsets phenotype. Findings: Our data shows that peripheral Vδ2+ phenotype, functional capacity (cytokines, cytotoxicity, proliferation) and gene expression profile are spec…

The memory improving effects of round scad (Decapterus maruadsi) hydrolysates on sleep deprivation-induced memory deficits in rats via antioxidant and neurotrophic pathways.

Sleep deprivation negatively influences memory formation and consolidation, which leads to memory impairment associated with oxidative stress and neurotrophic pathways. In this study, a sleep-deprived rat model was used to evaluate the protective effects of round scad hydrolysates (RSH, 333 and 666 mg per kg bw) on memory impairment and the underlying mechanisms. The result of the Morris water maze test revealed that RSH significantly reversed the cognition deficits induced by sleep deprivation. Moreover, RSH supplementation alleviated oxidative stress by increasing the activities of glutathione peroxidase and superoxide dismutase and the ratio of glutathione/oxidized glutathione in the brain. Furthermore, RSH significantly up-regulated the expression of antioxidant defense-related proteins, including nuclear factor E2-related factor 2 (Nrf2) and its downstream heme oxygenase-1 (HO-1), a…

Biological and psychosocial predictors of anxiety worsening in the postpartum period: A longitudinal study.

Background: As many as 20% of women will experience an anxiety disorder during the perinatal period. Women with pre-existing anxiety disorders are at increased risk of worsening during this time, yet little is known about its predictors. Study aim: To investigate the psychosocial and biological risk factors for anxiety worsening in the postpartum in women with pre-existing anxiety disorders. Methods: Thirty-five (n = 35) pregnant women with pre-existing DSM-5 anxiety disorders were enrolled in this prospective study investigating the psychosocial (e.g., childhood trauma, intolerance of uncertainty, depression) and biological risk factors (e.g. C-reactive protein, interleukin-6, tumor necrosis factor-α) for anxiety worsening in the postpartum period. Anxiety worsening was defined as an increase of ≥50% or greater on Hamilton Anxiety Rating Scale scores from the third trimester of pregnanc…
