Abstract
OBJECTIVE The objective of this study was to investigate possible immune cytokine trends throughout a week-long surgical simulation mass-casualty training session in order to determine the effects of stress inoculation on the immune system. METHODS Thirty-seven military medical students participated in a hyper-realistic surgical simulation training event conducted at Strategic Operations site in San Diego, California. Salivary samples were collected every morning of the stress training exercise for 4 consecutive days. Cortisol, along with a panel of 42 immune cytokines, was measured using multiplex enzyme-linked immunosorbent assays from Eve Technologies. The determined concentrations were averaged and plotted on a scatter plot, and then points were fit to a second-order polynomial trendline of best fit to measure. RESULTS The cytokines epidermal growth factor, growth-related oncogene-α, interleukin (IL)-1α, and platelet-derived growth factor-AA followed a noted pattern of cortisol decrease throughout the week. In addition, cytokines IL-27, granulocyte colony stimulating factor, IL-10, and IL-13 demonstrated a late peak, followed by a return to baseline at the conclusion of training. Finally, the cytokine monocyte chemoattractant protein-1 displayed a decline throughout the week followed by an increase on the last day of stress training. CONCLUSIONS Altogether, these results help to identify important biomarkers that may help to improve long-term stress adaptation and prevent post-traumatic stress disorder following exposure to repeated stress.

Euglena gracilis (Euglena) powder supplementation enhanced immune function through natural killer cell activity in apparently healthy participants: A randomized, double-blind, placebo-controlled trial. Nutr Res 2023; 119:90-97. [PMID: 37769481 DOI: 10.1016/j.nutres.2023.09.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Revised: 09/07/2023] [Accepted: 09/07/2023] [Indexed: 10/03/2023]
Abstract
Euglena gracilis (Euglena) is a microalgae found in most freshwater environments that produces paramylon, an insoluble β-1,3-glucan linked to human immunity. We hypothesized that Euglena powder has effects on immune function in apparently healthy adults. The study included male or female volunteers between the ages of 20 and 70 years who had white blood cell counts ranging from 4 × 103/µL to 10 × 103/µL, a "severe" rating on the stress questionnaire from the Korea National Health and Nutrition Examination Survey, and at least 2 upper respiratory infections with cold-like symptoms in the previous year. Participants received either a placebo or 700 mg of Euglena powder daily for 8 weeks. The study measured natural killer cell activity, cytokine concentrations, and blood lipid profiles to confirm the immune effect of Euglena consumption. In conclusion, Euglena improved immunological function through natural killer cell activity. Safety assessment showed no significant changes in vital signs or clinical chemistry indicators, and there were no adverse events associated with Euglena consumption. Euglena supplementation may help boost the immune systems of healthy individuals.

Abstract
Recent studies have proposed valid precision models and valid Research and Diagnostic Algorithmic Rules (RADAR) for recurrent major depressive disorder (MDD). The aim of the current study was to construct precision models and RADAR scores in patients experiencing first-episode MDD and to examine whether adverse childhood experiences (ACE) and negative life events (NLE) are associated with suicidal behaviors (SB), cognitive impairment, and phenome RADAR scores. This study recruited 90 patients with major depressive disorder (MDD) in an acute phase, of whom 71 showed a first-episode MDD (FEM), and 40 controls. We constructed RADAR scores for ACE; NLE encountered in the last year; SB; and severity of depression, anxiety, chronic fatigue, and physiosomatic symptoms using the Hamilton Depression and Anxiety Rating Scales and the FibroFatigue scale. The partial least squares analysis showed that in FEM, one latent vector (labeled the phenome of FEM) could be extracted from depressive, anxiety, fatigue, physiosomatic, melancholia, and insomnia symptoms, SB, and cognitive impairments. The latter were conceptualized as a latent vector extracted from the Verbal Fluency Test, the Mini-Mental State Examination, and ratings of memory and judgement, indicating a generalized cognitive decline (G-CoDe). We found that 60.8% of the variance in the FEM phenome was explained by the cumulative effects of NLE and ACE, in particular emotional neglect and, to a lesser extent, physical abuse. In conclusion, the RADAR scores and plots constructed here should be used in research and clinical settings, rather than the binary diagnosis of MDD based on the DSM-5 or ICD.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:5223.

Abstract
Since the start of the COVID-19 pandemic in early 2020, governments around the world have adopted an array of measures intended to control the transmission of the SARS-CoV-2 virus, using both pharmaceutical and non-pharmaceutical interventions (NPIs). NPIs are public health interventions that do not rely on vaccines or medicines and include policies such as lockdowns, stay-at-home orders, school closures, and travel restrictions. Although the intention was to slow viral transmission, emerging research indicates that these NPIs have also had unintended consequences for other aspects of public health. Hence, we conducted a narrative review of studies investigating these unintended consequences of NPIs, with a particular emphasis on mental health and on lifestyle risk factors for non-communicable diseases (NCD): physical activity (PA), overweight and obesity, alcohol consumption, and tobacco smoking. We reviewed the scientific literature using combinations of search terms such as 'COVID-19', 'pandemic', 'lockdowns', 'mental health', 'physical activity', and 'obesity'. NPIs were found to have considerable adverse consequences for mental health, physical activity, and overweight and obesity. The impacts on alcohol and tobacco consumption varied greatly within and between studies. The variability in consequences for different groups implies increased health inequalities by age, sex/gender, socioeconomic status, pre-existing lifestyle, and place of residence. In conclusion, a proper assessment of the use of NPIs in attempts to control the spread of the pandemic should be weighed against the potential adverse impacts on other aspects of public health. Our findings should also be of relevance for future pandemic preparedness and pandemic response teams.

Anti-apoptosis effect of recombinant human interleukin-11 in neonatal hypoxic-ischemic rats through activating the IL-11Rα/STAT3 signaling pathway. J Stroke Cerebrovasc Dis 2023; 32:106923. [PMID: 36521373 DOI: 10.1016/j.jstrokecerebrovasdis.2022.106923] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 11/21/2022] [Accepted: 12/04/2022] [Indexed: 12/15/2022] Open
Abstract
Hypoxia-ischemia (HI) is one of the most common causes of death and disability in neonates. Apoptosis contributes to HI development. Interleukin-11(IL-11) has been shown to protect mice from cerebral ischemia/reperfusion injury. However, whether IL-11 exerts the anti-apoptotic effect on HI injury is unclear. In this study, we demonstrated that recombinant human IL-11 (rhIL-11) prevented apoptosis of rat neonates with HI through activating IL-11Rα/STAT3 signaling. Sprague-Dawley rat pups on the 7th day after birth were used to establish an HI injury model. The expression levels of IL-11Rα and GP130 were increased first and then decreased after HI. In contrast, IL-11 expression was first decreased and then increased. Immunofluorescence staining showed that IL-11Rα was localized in neurons and oligodendrocytes. RhIL-11 treatment alleviated hippocampal and cortical damages, significantly reduced cerebral infarction volumes, cerebral edema, and loss of the Nissl body and nerve cells, and also ameliorated the outcomes of HI injury and long-term neurological deficits. In addition, rhIL-11 treatment upregulated the expressions levels of Bcl-2 and p-STAT3/STAT3, and downregulated the protein concentrations of the lytic protease, and cleaved-caspase-3. Furthermore, GP130 inhibitor and JAK1 inhibitor reversed the protective effects of rhIL-11. Overall, rhIL-11 showed an anti-apoptosis effect on the brain after HI injury. Our results indicated that rhIL-11 reduced neuronal apoptosis by activating the brain IL-11Rα/STAT3 pathway.

Controllable and Uncontrollable Stress Differentially Impact Fear Conditioned Alterations in Sleep and Neuroimmune Signaling in Mice. Life (Basel) 2022; 12:life12091320.

Abstract
Stress induces neuroinflammation and disrupts sleep, which together can promote a number of stress-related disorders. Fear memories associated with stress can resurface and reproduce symptoms. Our previous studies have demonstrated sleep outcomes can be modified by stressor controllability following stress and fear memory recall. However, it is unknown how stressor controllability alters neuroinflammatory signaling and its association with sleep following fear memory recall. Mice were implanted with telemetry transmitters and experienced escapable or inescapable footshock and then were re-exposed to the shuttlebox context one week later. Gene expression was assessed with Nanostring® panels using RNA extracted from the basolateral amygdala and hippocampus. Freezing and temperature were examined as behavioral measures of fear. Increased sleep after escapable stress was associated with a down-regulation in neuro-inflammatory and neuro-degenerative related genes, while decreased sleep after inescapable stress was associated with an up-regulation in these genes. Behavioral measures of fear were virtually identical. Sleep and neuroimmune responses appear to be integrated during fear conditioning and reproduced by fear memory recall. The established roles of disrupted sleep and neuroinflammation in stress-related disorders indicate that these differences may serve as informative indices of how fear memory can lead to psychopathology.

Abstract
The aim of this study was to evaluate the influence of β-endorphins and serotonin on the course of treatment, disease-free time, and overall survival of patients with ovarian cancer. This study may contribute to the identification of modifiable factors that may influence the treatment of ovarian cancer. The research was carried out in a group of 162 patients of which 139 respondents were included in the research; ovarian cancer was diagnosed in 78 of these patients. The study consisted of three stages. In the first stage of diagnostics, a survey among the patients was carried out. In the second stage-5 mL of blood was collected from each patient (n = 139) in the preoperative period to determine the concentration of β-endorphin and serotonin. In the third stage-blood samples were collected from those patients who had completed chemotherapy treatment or had surgery. Concentrations of β-endorphin and serotonin were measured by the Luminex method, using the commercial Luminex Human Discovery Assay kit. The average age of the patients was 62.99 years. The level of β-endorphin significantly differs among patients diagnosed with ovarian cancer and among patients in the control group (202.86; SD-15.78 vs. 302.00; SD-24.49). A lower level of β-endorphins was found in the patients with a recurrence of the neoplastic process compared to those without recurrence (178.84; SD-12.98 vs. 205.66; SD-13.37). On the other hand, the level of serotonin before chemotherapy was higher in the group of people with disease recurrence compared to those without recurrence (141.53; SD-15.33 vs. 134.99; SD-10.08). Statistically significantly positive correlations were found between the level of β-endorphin and both disease-free time (β-endorphin levels before chemotherapy: rho Spearman 0.379, p < 0.027; β-endorphin levels after chemotherapy: rho Spearman 0.734 p < 0.001) and survival time (β-endorphin levels before chemotherapy: rho Spearman 0.267, p < 0.018; β-endorphin levels after chemotherapy: rho Spearman 0.654 p < 0.001). 1. The levels of serotonin and β-endorphin levels are significantly related to ovarian cancer and change during treatment. 2. High mean preoperative concentrations of β-endorphins were significantly related to overall survival and disease-free time.

Abstract
Background Dysbiosis/imbalance in the gut microbial composition triggers chronic inflammation and promotes colorectal cancer (CRC). Modulation of the gut microbiome by the administration of probiotics is a promising strategy to reduce carcinogenic inflammation. However, the mechanism remains unclear. Methods In this study, we presented a systematic network, meta-analysis, and molecular docking studies to determine the plausible mechanism of probiotic intervention in diminishing CRC-causing inflammations. Results We selected 77 clinical, preclinical, in vitro, and in vivo articles (PRISMA guidelines) and identified 36 probiotics and 135 training genes connected to patients with CRC with probiotic application. The meta-analysis rationalizes the application of probiotics in the prevention and treatment of CRC. An association network is generated with 540 nodes and 1,423 edges. MCODE cluster analysis identifies 43 densely interconnected modules from the network. Gene ontology (GO) and pathway enrichment analysis of the top scoring and functionally significant modules reveal stress-induced metabolic pathways (JNK, MAPK), immunomodulatory pathways, intrinsic apoptotic pathways, and autophagy as contributors for CRC where probiotics could offer major benefits. Based on the enrichment analyses, 23 CRC-associated proteins and 7 probiotic-derived bacteriocins were selected for molecular docking studies. Results indicate that the key CRC-associated proteins (e.g., COX-2, CASP9, PI3K, and IL18R) significantly interact with the probiotic-derived bacteriocins (e.g., plantaricin JLA-9, lactococcin A, and lactococcin mmfii). Finally, a model for probiotic intervention to reduce CRC-associated inflammation has been proposed. Conclusion Probiotics and/or probiotic-derived bacteriocins could directly interact with CRC-promoting COX2. They could modulate inflammatory NLRP3 and NFkB pathways to reduce CRC-associated inflammation. Probiotics could also activate autophagy and apoptosis by regulating PI3K/AKT and caspase pathways in CRC. In summary, the potential mechanisms of probiotic-mediated CRC prevention include multiple signaling cascades, yet pathways related to metabolism and immunity are the crucial ones.

Abstract
BACKGROUND Early metabolic reorganization was only recently recognized as an essentially integrated part of immunology. In this context, unbalanced ROS/RNS levels connected to increased aerobic fermentation, which is linked to alpha-tubulin-based cell restructuring and control of cell cycle progression, were identified as a major complex trait for early de novo programming ('CoV-MAC-TED') during SARS-CoV-2 infection. This trait was highlighted as a critical target for developing early anti-viral/anti-SARS-CoV-2 strategies. To obtain this result, analyses had been performed on transcriptome data from diverse experimental cell systems. A call was released for wide data collection of the defined set of genes for transcriptome analyses, named 'ReprogVirus', which should be based on strictly standardized protocols and data entry from diverse virus types and variants into the 'ReprogVirus Platform'. This platform is currently under development. However, so far, an in vitro cell system from primary target cells for virus attacks that could ideally serve for standardizing the data collection of early SARS-CoV-2 infection responses has not been defined. RESULTS Here, we demonstrate transcriptome-level profiles of the most critical 'ReprogVirus' gene sets for identifying 'CoV-MAC-TED' in cultured human nasal epithelial cells infected by two SARS-CoV-2 variants differing in disease severity. Our results (a) validate 'Cov-MAC-TED' as a crucial trait for early SARS-CoV-2 reprogramming for the tested virus variants and (b) demonstrate its relevance in cultured human nasal epithelial cells. CONCLUSION In vitro-cultured human nasal epithelial cells proved to be appropriate for standardized transcriptome data collection in the 'ReprogVirus Platform'. Thus, this cell system is highly promising to advance integrative data analyses with the help of artificial intelligence methodologies for designing anti-SARS-CoV-2 strategies.

Abstract
Lysosomal storage diseases (LSDs) are characterized by the abnormal accumulation of substrates in tissues due to the deficiency of lysosomal proteins. Among the numerous clinical manifestations, chronic inflammation has been consistently reported for several LSDs. However, the molecular mechanisms involved in the inflammatory response are still not completely understood. In this study, we performed text-mining and systems biology analyses to investigate the inflammatory signals in three LSDs characterized by sphingolipid accumulation: Gaucher disease, Acid Sphingomyelinase Deficiency (ASMD), and Fabry Disease. We first identified the cytokines linked to the LSDs, and then built on the extracted knowledge to investigate the inflammatory signals. We found numerous transcription factors that are putative regulators of cytokine expression in a cell-specific context, such as the signaling axes controlled by STAT2, JUN, and NR4A2 as candidate regulators of the monocyte Gaucher disease cytokine network. Overall, our results suggest the presence of a complex inflammatory signaling in LSDs involving many cellular and molecular players that could be further investigated as putative targets of anti-inflammatory therapies.

Abstract
Despite the availability of hydroxyurea, the clinical use of the medication among patients with sickle cell disease (SCD) remains low in the United States. Given the high healthcare utilization cost, SCD requires new therapeutic approaches. Recent studies demonstrated bacterial overgrowth and dysbiosis-related intestinal pathophysiological changes in SCD. Intestinal microbes regulate neutrophil ageing. Aged and activated neutrophils contribute to the pathogenesis of vaso-occlusive crisis (VOC) in SCD. In this paper, we will review the pre-clinical and clinical data on how antibiotics might reduce the intestinal microbial density and influence the course of VOC. Based on these observations, we will discuss rationales for and potential challenges to antibiotic-based therapeutic approaches that may modify the clinical course of VOC in SCD.

Abstract
Reprogramming of primary virus-infected cells is the critical step that turns viral attacks harmful to humans by initiating super-spreading at cell, organism and population levels. To develop early anti-viral therapies and proactive administration, it is important to understand the very first steps of this process. Plant somatic embryogenesis (SE) is the earliest and most studied model for de novo programming upon severe stress that, in contrast to virus attacks, promotes individual cell and organism survival. We argued that transcript level profiles of target genes established from in vitro SE induction as reference compared to virus-induced profiles can identify differential virus traits that link to harmful reprogramming. To validate this hypothesis, we selected a standard set of genes named 'ReprogVirus'. This approach was recently applied and published. It resulted in identifying 'CoV-MAC-TED', a complex trait that is promising to support combating SARS-CoV-2-induced cell reprogramming in primary infected nose and mouth cells. In this perspective, we aim to explain the rationale of our scientific approach. We are highlighting relevant background knowledge on SE, emphasize the role of alternative oxidase in plant reprogramming and resilience as a learning tool for designing human virus-defense strategies and, present the list of selected genes. As an outlook, we announce wider data collection in a 'ReprogVirus Platform' to support anti-viral strategy design through common efforts.

Influence of Psychological Distress in Patients with Hypoallergenic Total Knee Arthroplasty. Treatment Algorithm for Patients with Metal Allergy and Knee Osteoarthritis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18115997. [PMID: 34204981 PMCID: PMC8199888 DOI: 10.3390/ijerph18115997] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Revised: 05/27/2021] [Accepted: 05/29/2021] [Indexed: 12/19/2022]
Abstract
The outcome in total knee arthroplasty (TKA) depends on multiples factors, among them is the psychological condition. In addition, up 15 to 30% of the patients that undergo TKA show little or no improvement after surgery, which implies the diagnosis of a painful TKA is a challenge for the orthopedic surgeon, who must rule out a possible metal allergy (MA). It is considered an exclusion diagnosis. Due to the complex relationship between psychological condition and MA, and according to the worse results in patients treated with a hypoallergenic TKA, we asked: (1). What degree of psychological distress (PD) is present in patients who have a hypoallergenic TKA, and how does it influence the results of quality of life (QoL) and functional capacity. (2). Can we develop a new algorithm for patients with a possible MA that improves the outcomes? A pragmatic clinical study was carried out that included patients who underwent hypoallergenic TKA during three consecutive years. Quality of life and functional capacity were measured with (Western Ontario McMaster Universities Osteoarthritis Index) WOMAC index, the Short Form 12 questionnaire (SF-12) questionnaire, and the The EQ-5D-5L questionnaire essentially consists of two pages: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS) (Euro-QoL-5D L-VAS (EQ5D)), in all patients. To assess PD, a Psychological Distress Score was developed. SPSS software was performed to statistical analysis, and Student´s test for independent variables with a p < 0.005 as statistically significant. A total of 72 anallergic TKAs in 64 patients were treated during this period; 31.3% of these patients showed features of PD before the surgery. According with the severity of the PD, 60% were classified as severe, 10% as moderate and 30% as mild. Patients with PD had statistically significant worse results on the final WOMAC, SF-12, and EQ5D questionnaires. The final scores of the physical subscale of the SF-12 and EQ5D showed better results in patients diagnosed by psychiatrist. Up to one third of the patients with hypoallergenic TKAs have PD, and their results are clearly inferior to those patients with MA without PD. When PD was diagnosed according with Psychological Distress Score, patients should be carefully assessed in order to determine if a specialist referral is recommended. According with our results, PD should be assessed either by the PCP or by us. If the PD is confirmed, a psychiatry referral is then requested for better preoperative management and treatment. We believe that this approach would lead to better TKA outcomes.

Abstract
With the alarming rise of infected cases and deaths, COVID-19 is a pandemic, affecting 220 countries worldwide. Until now, no specific treatment is available against SARS-CoV-2. The causal virus SARS-CoV-2 primarily infects lung cells, leading to respiratory illness ranging in severity from the common cold to deadly pneumonia. This, with comorbidities, worsens the clinical outcome, particularly for immunosuppressed individuals with COVID-19. Interestingly, the commensal gut microbiota has been shown to improve lung infections by modulating the immune system. Therefore, fine-tuning of the gut microbiome with probiotics could be an alternative strategy for boosting immunity and treating COVID-19. Here, we present a systematic biological network and meta-analysis to provide a rationale for the implementation of probiotics in preventing and/or treating COVID-19. We have identified 90 training genes from the literature analysis (according to PRISMA guidelines) and generated an association network concerning the candidate genes linked with COVID-19 and probiotic treatment. The functional modules and pathway enrichment analysis of the association network clearly show that the application of probiotics could have therapeutic effects on ACE2-mediated virus entry, activation of the systemic immune response, nlrp3-mediated immunomodulatory pathways, immune cell migration resulting in lung tissue damage and cardiovascular difficulties, and altered glucose/lipid metabolic pathways in the disease prognosis. We also demonstrate the potential mechanistic domains as molecular targets for probiotic applications to combat the viral infection. Our study, therefore, offers probiotics-mediated novel preventive and therapeutic strategies for COVID-19 warfare.

Abstract
OBJECTIVE To determine factors of innate and acquired immunity in adaptation disorders with a predominance of asthenic or anxiety-depressive syndrome. MATERIAL AND METHODS Twenty-five patients with ICD-10 diagnosis of «Adaptation Disorders» (F43.2), including 9 with asthenic syndrome and 16 with anxiety-depressive syndrome, were examined. The control group consisted of 23 healthy individuals. The relative number of lymphocyte phenotypes was determined by flow cytometry; the concentration of IgM, IgG, IgA, aAB to S100b and MBP - by ELISA; CIC level - by the method of selective precipitation with PEG-6000; phagocytic activity of neutrophils by a test system with melamine-formaldehyde latex; activities of leukocyte elastase (LE) and α1-proteinase inhibitor (α1-PI) by a spectrophotometric method. RESULTS There were significant changes in the parameters of acquired immunity in the group with asthenic syndrome and those of innate immunity in the group with anxiety-depressive syndrome. An increase in α1-PI activity, in the total number of significant correlations between different immunological parameters, in the involvement of α1-PI in integration of acquired and innate immunity were observed in the anxiety-depressive group compared with the asthenic group. CONCLUSIONS The peculiarities of stress response in patients with leading anxiety-depressive syndrome are the high activity of α1-PI, which, along with the strengthening of correlation intersystem associations and the involvement of this protein in the integration of acquired and innate immunity, allows us to consider α1-PI as a criterion that improves the accuracy of diagnosis of the nature of the course of adaptation disorders.

Abstract
Psychological stress is an important cause to induce various metabolic disorders such as obesity, type II diabetes, and cardiovascular disorders by affecting the visceral adipose tissue. Pathophysiology of these diseases is often accompanied by the hyperactive immune system. The hyperactive immune system causes immune cells to infiltrate in the adipose tissue to increase the severity of metabolic disorders and to affect the levels of stress associated hormones, such as cortisol and serotonin. Cortisol and serotonin, alone or together, could regulate several aspects of the metabolic and immunological deregulations by manipulating the lipid accumulation or adipogenesis in cells. During adipogenesis, macrophages are recruited. Previous reports from the Aich laboratory established the roles of cortisol and serotonin to influence adipogenesis in pre-adipocytes 3T3-L1 in the presence and absence of macrophages. In the current study, we reported the role of macrophage RAW264.7, especially its polarized states, on differentiated murine adipocytes 3T3-L1 in the presence or absence of cortisol and serotonin. The current study also compares the differential role of macrophage recruitment on pre- and differentiated adipocytes.

Abstract
Evidences showed that chronic stress (CS) can aggravate the situation of nonalcoholic fatty liver disease (NAFLD). Vitexin is one of the major components in hawthorn, which is widely used to reduce blood lipid. This study was aimed to explore the therapeutic effects and potential mechanisms of vitexin on chronic stress mice with high-fat diet (CSHFD). The results showed that 5-week vitexin administration (40 mg/kg, i.g.) could obviously reduce hepatic fat deposition, alleviate lipid metabolism, and inhibit liver inflammation in CSHFD mice. In addition, vitexin significantly reduced hepatic macrophage infiltration, obviously down-regulated the mRNA and protein expressions of hepatic SREBP-1c, FAS, ACC. Moreover, we also found that vitexin treatment could significantly inhibit the expressions of TLR4/NF-κB signaling in CSHFD mice. This results suggested that vitexin could ameliorate chronic stress combined with high-fat diet induced NAFLD, and its mechanisms is closely related to inhibit TLR4/NF-κB signaling and reduce fatty acid synthesis proteins.

Paternal restraint stress affects offspring metabolism via ATF-2 dependent mechanisms in Drosophila melanogaster germ cells. Commun Biol 2020; 3:208.

Abstract
Paternal environmental factors can epigenetically influence gene expressions in offspring. We demonstrate that restraint stress, an experimental model for strong psychological stress, to fathers affects the epigenome, transcriptome, and metabolome of offspring in a MEKK1-dATF2 pathway-dependent manner in Drosophila melanogaster. Genes involved in amino acid metabolism are upregulated by paternal restraint stress, while genes involved in glycolysis and the tricarboxylic acid (TCA) cycle are downregulated. The effects of paternal restraint stress are also confirmed by metabolome analysis. dATF-2 is highly expressed in testicular germ cells, and restraint stress also induces p38 activation in the testes. Restraint stress induces Unpaired 3 (Upd3), a Drosophila homolog of Interleukin 6 (IL-6). Moreover, paternal overexpression of upd3 in somatic cells disrupts heterochromatin in offspring but not in offspring from dATF-2 mutant fathers. These results indicate that paternal restraint stress affects metabolism in offspring via inheritance of dATF-2-dependent epigenetic changes. Ki-Hyeon Seong et al. report that paternal environmental stress affects the metabolism of their offspring in Drosophila melanogaster. They exposed male flies to stress by preventing them from moving for 10 hours at a time and then measured gene expression and metabolite levels in their offspring, who showed increased expression of amino acid and one-carbon metabolism-related genes and downregulation of glycolysis and the TCA cycle.

Abstract
AIM Endorphins are endogenous morphine, neuropeptides, produced in the pituitary gland in response to stress and pain. There are three types of endorphins beta-endorphins, enkephalins, and dynorphins binds to mu, kappa, and delta receptors situated on nervous system and immune cells. Cancer is a major threat to mankind killing millions of people around the world annually. There has been recent advancements in the field of surgery, chemotherapy, and radiotherapy, still the prognosis of cancer patients not improved much with increasing morbidity. We can't kill cancer cells without killing normal cells. Cancer cells and normal cells work alike. The aim of the review was to determine the anticancer activities of beta-endorphins. MATERIALS AND METHODS Articles regarding endorphins and its therapeutic application in cancer were searched on PubMed and Google scholar. This review includes studies, reviews, clinical trials and key findings of my research were included in the manuscript. RESULTS Beta-endorphin is an abundant endorphin, potent than morphine, synthesized and secreted in the anterior pituitary gland, it is a precursor of POMC (proopiomelanocortin). It has got various mechanisms of action such as analgesic activity, anti-inflammatory activity, immune stimulatory activity, stress buster activity, and euphoric activity. CONCLUSION Beta endorphin is an abundant endogenous morphine used for natural holistic preventive, therapeutic, promotive, and palliative treatment of cancer without adverse effects and inexpensive.

Abstract
INTRODUCTION Burnout and depression is higher in trauma surgeons as compared to surgeons in other specialties. Clinical practice for many acute care surgeons (ACS) includes in-house call (IHC). The goal of this study was to quantitate physiologic stress among ACS who take IHC. METHODS ACS with IHC responsibilities from two Level I trauma centers were studied. Participants wore a fitness and heart rate variability (HRV) device over 3 months. HRV was categorized as normal if 85% of baseline, moderate stress when HRV <85% but >50%, and high stress when HRV< 50%. RESULTS 1421 nights were recorded among 17 surgeons (35.3% female; mean age 45.5 years). Excluding IHC, mean HRV = 32.23, and 95.63% of days were consistent with moderate or high stress. Post-call day 2 had significantly highest percentage of high stress (65.82%, p = 0.0495). High and moderate stress levels returned to baseline on post-call day 3. CONCLUSIONS High and moderate stress beyond IHC is common among ACS. Future study is needed to determine consequences of persistent stress and identify factors which impact recovery after IHC.

Abstract
Antenatal depression affects ~9-19% of pregnant women and can exert persistent adverse effects on both mother and child. There is a need for a deeper understanding of antenatal depression mechanisms and the development of tools for reliable diagnosis and early identification of women at high risk. As the use of untargeted blood metabolomics in the investigation of psychiatric and neurological diseases has increased substantially, the main objective of this study was to investigate whether untargeted gas chromatography-mass spectrometry (GC-MS) plasma metabolomics in 45 women in late pregnancy, residing in Uppsala, Sweden, could indicate metabolic differences between women with and without depressive symptoms. Furthermore, seasonal differences in the metabolic profiles were explored. When comparing the profiles of cases with controls, independently of season, no differences were observed. However, seasonal differences were observed in the metabolic profiles of control samples, suggesting a favorable cardiometabolic profile in the summer vs. winter, as indicated by lower glucose and sugar acid concentrations and lactate to pyruvate ratio, and higher abundance of arginine and phosphate. Similar differences were identified between cases and controls among summer pregnancies, indicating an association between a stressed metabolism and depressive symptoms. No depression-specific differences were apparent among depressed and non-depressed women, in the winter pregnancies; this could be attributed to an already stressed metabolism due to the winter living conditions. Our results provide new insights into the pathophysiology of antenatal depression, and warrant further investigation of the use of metabolomics in antenatal depression in larger cohorts.

Abstract
Significant uncertainty surrounds the sustainability of healthcare services in which junior doctors work. It is essential that student and foundation doctors (SFDs) are actively engaged if workforce morale is rebuilt. This narrative review explores the evidence driving the individual work-streams of the Royal College of Physicians' newly formed Student and Foundation Doctor Network. Undergraduate and postgraduate training reform has coincided with concerning feedback from newly qualified doctors. System-level efforts to address this include a focus on extra-contractual matters, where small, sustainable changes could address training and work issues.Fewer foundation year-2 doctors are entering specialty training immediately after the foundation programme. Providing dedicated careers guidance and highlighting opportunities within traditional placements and other career paths can support doctors who undertake non-traditional career routes, including those who take time out of programme.Disseminating these resources through an effective peer-to-peer framework and a well-established mentoring scheme could be the most appropriate way to spread good practice.

Abstract
The aim of the present study was to determine the influence of stress on the colonic mucosa and immune system and to further investigate the association between stress and development and pathogenesis of ulcerative colitis (UC). Mice were treated with 2,4,6-trinitrobenzenesulfonic acid to induce an animal model of UC, and stress was induced by water immersion and restraint. Subsequently, the disease activity index (DAI), secretory immunoglobulin A (sIgA), IgA, interleukin (IL)-6 and -8, tumor necrosis factor-α (TNF-α), complement component (C)3 and C4, and alterations in the colonic mucosa were observed. The DAI scores and the expression levels of IL-6, IL-8 and TNF-α significantly increased in the experimental UC mice compared with the control mice, while the expression levels of IgA and sIgA decreased (all P<0.01). DAI and colonic mucosa damage scores increased in the stress-treated mouse models of UC compared with the untreated mouse models of UC (P<0.05). Expression levels of IgA and sIgA decreased, while IL-6, IL-8 and TNF-α further increased in the stress-treated UC mice (P<0.05). The expression levels of C3 and C4 were not affected by stress or UC (P>0.05). These results indicated that UC may be associated with an immune disorder and that stress can aggravate colonic mucosa injury and alter the immune response. Furthermore, stress and immunity may serve roles in the pathogenesis of UC.

Abstract
Stress response refers to the systemic nonspecific response upon exposure to strong stimulation or chronic stress, such as severe trauma, shock, infection, burn, major surgery or improper environment, which disturb organisms and damage their physical and psychological health. However, the pathogenesis of stress induced disorder remains complicated and diverse under different stress exposure. Recently, studies have revealed a specific role of microRNAs (miRNAs) in regulating cellular function under different types of stress, suggesting a significant role in the treatment and prevention of stress-related diseases, such as stress ulcer, posttraumatic stress disorder, stress-induced cardiomyopathy and so on. This paper have reviewed the literature on microRNA related stress diseases in different databases including PubMed, Web of Science, and the MiRbase. It considers only peer-reviewed papers published in English between 2004 and 2018. This review summarizes new advances in principles and mechanisms of miRNAs regulating stress signalling pathway and the role of miRNAs in human stress diseases. This comprehensive review is to provide an integrated account of how different stresses affect miRNAs and how stress-miRNA pathways may, in turn, be linked with disease, which offers some potential strategies for stress disorder treatment. Furthermore, the limitation of current studies and challenges for clinical use are discussed.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Akebia quinata Decaisne extract (AQE; Lardizabalaceae) is used in traditional herbal medicine for stress- and fatigue-related depression, improvement of fatigue, and mental relaxation. AIM OF THE STUDY To clarify the effects of AQE on stress-induced fatigue, we investigated the neuroprotective pharmacological effects of A. quinata Decaisne in mice exposed to chronic restraint stress. MATERIALS AND METHODS Seven-week old C57BL/6 mice chronically stressed by immobilization for 3 h daily for 15 d and non-stressed control mice underwent daily oral administration of AQE or distilled water. The open field, sucrose preference, and forced swimming behavioral tests were carried out once weekly, and immunohistochemical analyses of NeuN, brain-derived neurotrophic factor (BDNF), phosphorylated cAMP response element-binding (CREB) protein, and BDNF receptor tropomyosin receptor kinase B (TrkB) in striatum and hippocampus were performed at the end of the experimental period. Brain levels of serotonin, adrenaline, and noradrenaline as well as serum levels of corticosterone were measured. RESULTS Behavioral tests showed that treatment with AQE improved all lethargic behaviors examined. AQE significantly attenuated the elevated levels of adrenaline, noradrenaline, and serotonin in the brain and corticosterone, alanine transaminase, and aspartate transaminase levels in the serum. Histopathological analysis showed that AQE reduced liver injury and lateral ventricle size in restraint-stress mice via inhibition of neuronal cell death. Immunohistochemical analysis showed increased phosphorylation of CREB and expression of BDNF and its receptor TrkB in striatum and hippocampus. Chlorogenic acid, isochlorogenic acid A, and isochlorogenic acid C were identified as the primary components of AQE. All three agents increased expression of BDNF in SH-SY5Y cells and PC12 cells with H2O2-induced neuronal cell damage. CONCLUSIONS AQE may have a neuroprotective effect and ameliorate the effects of stress and fatigue-associated brain damage through mechanisms involving regulation of BDNF-TrkB signaling.

Abstract
Epidemiological studies implicate stress as an important factor contributing to the increasing prevalence of metabolic disorders. Studies have correlated visceral obesity and atherosclerosis with hyper-cortisolemia, a sequela of chronic psychological stress in humans and animals. Although several hormonal markers of stress have been associated with various metabolic disorders, the mechanism by which these hormones alter metabolic functions have not been established. We used an in vitro model system, culturing 3T3-L1 pre-adipocytes and RAW 264.7 macrophages in the presence or absence of cortisol, to analyze cell signaling pathways mediating changes in metabolic functions. Our analysis revealed that cortisol up-regulated the expression and function of two serotonin (S) receptors, HTR2c and HTR5a. HTR2c and HTR5a were also directly involved in mediating cortisol enhanced adipogenesis when pre-adipocytes were cultured alone or in the presence of macrophages. Finally, cortisol treatment of pre-adipocytes co-cultured with macrophages enhanced adipogenesis in both macrophages and pre-adipocytes.

Abstract
Objective To compare the prevalence of work-related protective and risk factors among Black and Latino male firefighters and to examine the association of these factors to perceived stress among both ethnic groups. Design Setting Participants Participants included 1,036 male, career firefighters who self-identified as Black (n=477) or Latino (n=559) from a large fire department in a major metropolitan city in the southwestern United States. As part of a department-wide suicide prevention program conducted in 2008, participants completed an anonymous and voluntary mental health needs survey. Measures The needs survey included questions regarding prevalence of work-related protective and risk factors, the RAPS-4 to assess substance abuse problems, and the 10-item Perceived Stress Scale. Results Results of regression analyses indicated that for both Black and Latino male firefighters, alcohol abuse (β =.13, β =.22), self-reported good health (β = -.23, β =-.24) and a positive partner/spouse relationship (β =-.14, β = -.15) were related to perceived stress. In addition, having a second job (β = .12) and a sense of life calling (β =-.10) were related to perceived stress only among Latino firefighters. All associations were in the expected direction as indicated by the signs of the standardized beta coefficients (β). Conclusion Black and Latino male firefighters reported relatively high levels of perceived stress. However, there were both differences and similarities in the factors associated to perceived stress among the ethnic groups. Therefore, interventions to help firefighters reduce or manage stress need to take into account that factors associated with perceived stress may vary by ethnic group.

Abstract
The underlying mechanisms of glucocorticoid (GC)-induced avascular necrosis of the femoral head (ANFH) have yet to be fully understood, in particular the mechanisms associated with the change of gene expression pattern. The present study aimed to identify key genes with a differential expression pattern in GC-induced ANFH. E-MEXP-2751 microarray data were downloaded from the ArrayExpress database. Differentially expressed genes (DEGs) were identified in 5 femoral head samples of steroid-induced ANFH rats compared with 5 placebo-treated rat samples. Gene Ontology (GO) and pathway enrichment analyses were performed upon these DEGs. A total 93 DEGs (46 upregulated and 47 downregulated genes) were identified in GC-induced ANFH samples. These DEGs were enriched in different GO terms and pathways, including chondrocyte differentiation and detection of chemical stimuli. The enrichment map revealed that skeletal system development was interconnected with several other GO terms by gene overlap. The literature mined network analysis revealed that 5 upregulated genes were associated with femoral necrosis, including parathyroid hormone receptor 1 (PTHR1), vitamin D (1,25-Dihydroxyvitamin D3) receptor (VDR), collagen, type II, α1, proprotein convertase subtilisin/kexin type 6 and zinc finger protein 354C (ZFP354C). In addition, ZFP354C and VDR were identified to transcription factors. Furthermore, PTHR1 was revealed to interact with VDR, and α-2-macroglobulin (A2M) interacted with fibronectin 1 (FN1) in the PPI network. PTHR1 may be involved in GC-induced ANFH via interacting with VDR. A2M may also be involved in the development of GC-induced ANFH through interacting with FN1. An improved understanding of the molecular mechanisms underlying GC-induced ANFH may provide novel targets for diagnostics and therapeutic treatment.

Abstract
BACKGROUND/OBJECTIVES The present study investigated the hypothesis that a highly pure linear β-1,3-glucan produced by Agrobacterium sp. R259 enhances human natural killer (NK) cell activity and suppresses pro-inflammatory cytokines. SUBJECTS/METHODS In an eight-week, double-blind, randomized, placebo-controlled clinical trial, 83 healthy adults with white blood cell counts of 4,000-8,000 cells/µL were participated and randomly assigned to take two capsules per day containing either 350 mg β-1,3-glucan or placebo. Six participants withdrew their study consent or were excluded due to NK cell activity levels outside the normal range. NK cell activity and serum levels of immunoglobulin G (IgG) and cytokines, such as interferon (IFN)-γ, interleukin (IL)-2, IL-4, IL-6, IL-10, IL-12 and tumor necrosis factor (TNF)-α were measured. RESULTS NK cell activity and the serum levels of IL-10 were significantly higher from baseline to week 8 in the β-glucan group compared with the placebo group (P = 0.048, P = 0.029). Consumption of β-1,3-glucan also significantly increased NK cell activity compared with placebo after adjusting for smoking and stress status (P = 0.009). In particular, the effect of β-1,3-glucan on NK cell activity was greater in participants with severe stress than in those experiencing mild stress. However, the administration β-1,3-glucan did not significantly modulate the levels of IFN-γ, IL-2, IL-4, IL-6, IL-12, TNF-α and IgG compared with the placebo. CONCLUSION The results showed that supplementation with bacterial β-1,3-glucan significantly increased NK cell activity without causing any adverse effects. Additionally, the beneficial effect of β-1,3-glucan on NK cell activity was greater in participants experiencing severe stress.

Abstract
Adrenal gland weight (AW) and corticomedullary ratio (ACMR) are used as indicators of stress in animals. Captive cheetahs (Acinonyx jubatus) have higher ACMRs than free-ranging ones and stress has been linked to gastritis, amyloidosis, glomerulosclerosis, and myocardial fibrosis. We reviewed age, sex, body weight (BW), kidney weight (KW), and left AW and ACMR with necropsy findings in 51 South African captive cheetahs. Eleven common histopathologic lesions were counted for each animal as measure of its disease burden. Adrenal corticomedullary hyperplasia was significantly correlated with left AW and ACMR. Males had significantly higher AWs than females; other parameters showed no difference between the sexes. Disease burden, gastritis, and myocardial fibrosis were moderately correlated with adrenal morphology supporting prior evidence that gastritis and myocardial fibrosis are linked to stress. Glomerulosclerosis was not correlated with adrenal morphology and neither kidney nor liver amyloidosis contributed significantly to variation in AW or ACMR on multivariate analyses. Interstitial nephritis showed much stronger correlations with kidney and liver amyloidosis than gastritis. All three adrenal parameters were correlated with age; age was the only significant variable affecting ACMR on the multivariate analyses; and disease burden as well as systemic amyloidosis and kidney disease (except for fibrosis) showed moderate correlations with age. Age may, therefore, be important in the pathogenesis of disease in captive cheetahs, particularly of amyloidosis and kidney disease. None of the intrinsic measurements or adrenal parameters were sufficiently closely linked to disease to be used as ante-mortem proxies for disease burden or specific diseases.

Abstract
AIM To assess plasma levels of cortisol and cytokines between cocaine-dependent women with and without childhood maltreatment (CM) history during cocaine detoxification treatment. METHOD We assessed immunoendocrine and clinical parameters of 108 crack cocaine female users during 3 weeks of inpatient detoxification treatment, and 24 healthy women to obtain reference values. Women with (CM+, n=53) or without (CM-, n=55) CM history were identified answering the Childhood Trauma Questionnaire (CTQ). Blood samples and clinical assessment were collected before lunch during the first, second and third week post-treatment admission. Flow cytometry was used to assess TNF-α, IFN-γ, IL-2, IL-4, IL-6, IL-10, IL-17A plasma levels and ELISA assay was used to measure plasma cortisol levels. RESULTS At baseline, lower Th1 and Th17-related cytokines levels and higher Th2 cytokines levels were observed in crack cocaine users compared with reference values. Cytokines levels of cocaine dependents gradually became closer to reference values along detoxification treatment. However, when CM+ and CM- groups were compared, increased levels of IL-6, IL-4 and TNF-α across time were observed in CM+ group only. Additionally, a Th1/Th2 immune imbalance was observed within CM+ group, which was negatively correlated with the severity of the crack withdrawal. Finally, loading trauma exposure severity, immunoendocrine and clinical parameters in factor analysis, we identified three clusters of observed variables during detoxification: (1) systemic immunity and trauma exposure, (2) pro-inflammatory immunity and (3) behavior CONCLUSION Our results suggest the existence of an immunological phenotype variant associated with CM exposure during crack cocaine detoxification of women.

Abstract
OBJECTIVE To identify the factors associated with 'good' mental health among Aboriginal children living in urban communities in New South Wales, Australia. DESIGN Cross-sectional survey (phase I of a longitudinal study). SETTING 4 Aboriginal Community Controlled Health Services that deliver primary care. All services were located in urban communities in New South Wales, Australia. PARTICIPANTS 1005 Aboriginal children aged 4-17 years who participated in phase I of the Study of Environment on Aboriginal Resilience and Child Health (SEARCH). PRIMARY OUTCOME MEASURE Carer report version of the Strengths and Difficulties Questionnaire. Scores <17 were considered to indicate 'good' mental health for the purposes of this article. RESULTS The majority (72%) of SEARCH participants were not at high risk for emotional or behavioural problems. After adjusting for the relative contributions of significant demographic, child and carer health factors, the factors associated with good mental health among SEARCH children were having a carer who was not highly psychologically distressed (OR=2.8, 95% CI 1.6 to 5.1); not suffering from frequent chest, gastrointestinal or skin infections (OR=2.8, 95% CI 1.8 to 4.3); and eating two or more servings of vegetables per day (OR=2.1, 95% CI 1.2 to 3.8). Being raised by a foster carer (OR=0.2, 95% CI 0.01 to 0.71) and having lived in 4 or more homes since birth (OR=0.62, 95% CI 0.39 to 1.0) were associated with significantly lower odds of good mental health. Slightly different patterns of results were noted for adolescents than younger children. CONCLUSIONS Most children who participated in SEARCH were not at high risk for emotional or behavioural problems. Promising targets for efforts to promote mental health among urban Aboriginal children may include the timely provision of medical care for children and provision of additional support for parents and carers experiencing mental or physical health problems, for adolescent boys and for young people in the foster care system.

Abstract
Oral diseases constitute a major worldwide public health problem, with their burden concentrating in socially disadvantaged and less affluent groups of the population, resulting in significant oral health inequalities. Biomedical and behavioural approaches have proven relatively ineffective in reducing these inequalities, and have potentially increased the health gap between social groups. Some suggest this stems from a lack of understanding of how the social and psychosocial contexts in which behavioural and biological changes occur influence oral disease. To unravel the pathways through which social factors affect oral health outcomes, a better understanding is thus needed of how the social 'gets under the skin,' or becomes embodied, to alter the biological. In this paper, we present the current knowledge on the interplay between social and biological factors in oral disease. We first provide an overview of the process of embodiment in chronic disease and then evaluate the evidence on embodiment in oral disease by reviewing published studies in this area. Results show that, in periodontal disease, income, education and perceived stress are correlated with elevated levels of stress hormones, disrupted immune biomarkers and increased allostatic load. Similarly, socioeconomic position and increased financial stress are related to increased stress hormones and cariogenic bacterial counts in dental caries. Based on these results, we propose a dynamic model depicting social-biological interactions that illustrates potential interdependencies between social and biological factors that lead to poor oral health. This work and the proposed model may aid in developing a better understanding of the causes of oral health inequalities and implicate the importance of addressing the social determinants of oral health in innovating public health interventions.

Abstract
Wild house mice form social hierarchies with aggressive males defending territories, in which females, young mice and submissive adult males share nests. In contrast, socially excluded males are barred from breeding groups, have numerous bite wounds and patches of thinning fur. Since their feeding times are often disrupted, we investigated whether social exclusion leads to changes in epigenetic marks of metabolic genes in liver tissue. We used chromatin immunoprecipitation and quantitative PCR to measure enrichment of two activating histone marks at 15 candidate loci. The epigenetic profiles of healthy males sampled from nest boxes differed significantly from the profiles of ostracized males caught outside of nests and showing bite wounds indicative of social exclusion. Enrichment of histone-3 lysine-4 trimethylation (H3K4me3) changed significantly at genes Cyp4a14, Gapdh, Nr3c1, Pck1, Ppara, and Sqle. Changes at histone-3 lysine-27 acetylation (H3K27ac) marks were detected at genes Fasn, Nr3c1, and Plin5. A principal components analysis separated the socialized from the ostracized mice. This was independent of body weight for the H3K4me3 mark, and partially dependent for H3K27ac. There was no separation, however, between healthy males that had been sampled from two different nests. A hierarchical cluster analysis also separated the two phenotypes, which was independent of body weight for both markers. Our study shows that a period of social exclusion during adult life leads to quantitative changes in histone modification patterns in mouse liver tissue. Similar epigenetic changes might occur during the development of stress-induced metabolic disorders in humans.

Hypothalamic KISS1 expression, gonadotrophin-releasing hormone and neurotransmitter innervation vary with stress and sensitivity in macaques. J Neuroendocrinol 2014; 26:267-81.

Abstract
The present study examined the effect of short-term psychosocial and metabolic stress in a monkey model of stress-induced amenorrhaea on the hypothalamic-pituitary-gonadal axis. KISS1 expression was determined by in situ hybridisation in the infundibular arcuate nucleus. Downstream of KISS1, gonadotrophin-releasing hormone (GnRH) axons in lateral areas rostral to the infundibular recess, serum luteinising hormone (LH) and serum oestradiol were measured by immunohistochemistry and radioimmunoassay. Upstream of KISS1, norepinephrine axons in the rostral arcuate nucleus and serotonin axons in the anterior hypothalamus and periaqueductal grey were measured by immunohistochemistry. Female cynomolgus macaques (Macaca fascicularis) characterised as highly stress resilient (HSR) or stress sensitive (SS) were examined. After characterisation of stress sensitivity, monkeys were either not stressed, or mildly stressed for 5 days before euthanasia in the early follicular phase. Stress consisted of 5 days of 20% food reduction in a novel room with unfamiliar conspecifics. There was a significant increase in KISS1 expression in HSR and SS animals in the presence versus absence of stress (P = 0.005). GnRH axon density increased with stress in HSR and SS animals (P = 0.015), whereas LH showed a gradual but nonsignificant increase with stress. Oestradiol trended higher in HSR animals and there was no effect of stress (P = 0.83). Norepinephrine axon density (marked with dopamine β-hydroxylase) increased with stress in both HSR and SS groups (P ≤ 0.002), whereas serotonin axon density was higher in HSR compared to SS animals and there was no effect of stress (P = 0.03). The ratio of dopamine β-hydroxylase/oestradiol correlated with KISS1 (P = 0.052) and GnRH correlated with serum LH (P = 0.039). In conclusion, oestradiol inhibited KISS1 in the absence of stress, although stress increased norepinephrine, which may over-ride oestradiol inhibition of KISS1 expression. We speculate that neural pathways transduce stress to KISS1 neurones, which changes their sensitivity to oestradiol.

Abstract
Increasing evidence shows that psychological stress can have dramatic impacts on the immune system, particularly the cutaneous immune response in dermatological disorders. While there have been many studies examining the impact of acute psychological stress on contact hypersensitivity there are relatively few studies concerning the impact of chronic psychological stress. Furthermore, the local immunological mechanisms by which chronic psychological stress impacts contact hypersensitivity still remain to be explored. Here we show that restraint-induced chronic psychological stress stimulates activation of the hypothalamus-pituitary-adrenal axis and delays weight gain in female BALB/c mice. We observed that chronic psychological stress reduces the cutaneous immune response as evidence by reduced ear swelling. This correlated with a significant decrease in the inflammatory cell infiltrate. On the other hand, chronic psychological stress does not influence T cell proliferation, activation, or sensitivity to corticosterone but does increase CD4(+) and CD8(+) T cell percentages in draining lymph nodes during a contact hypersensitivity reaction. Chronic psychological stress induces a decrease in overall circulating white blood cells, lymphocytes, and monocytes during a contact hypersensitivity reaction suggesting extravasation from the circulation. Finally, we found markedly reduced local IFN-γ production in chronically stressed animals. Based on these findings we propose that chronic psychological stress reduces contact hypersensitivity due to dysregulated cell trafficking and reduced production of IFN-γ.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Uwhangchungsimwon (UCW) is a representative traditional herbal medicine for central nervous system disorders in East Asia countries over thousand years. To evaluate the pharmacological effects of UCW against oxidative brain injury in a chronic restraint stress mice model. METHODS AND MATERIALS C57BL/6 male mice underwent daily oral administration of distilled water, UCW or ascorbic acid 1h before induction of restraint stress (5h of immobilization daily for 14 days). Nitric oxide (NO), total reactive oxygen species (ROS) levels, malondialdehyde, protein carbonyl contents, and activities of antioxidant enzymes, and concentrations of corticosterone, adrenaline, noradrenaline, and dopamine, were measured in brain tissues or sera. RESULTS Restraint stress notably increased NO and ROS levels, malondialdehyde and protein carbonyl contents in brain tissues, but decreased activities of catalase, glutathione reductase and glutathione peroxidase. These alterations were significantly ameliorated by UCW. UCW significantly attenuated the elevated serum concentrations of corticosterone, adrenaline and noradrenaline. UCW also significantly normalized the gene expressions in brain tissues altered by restraint stress; up-regulation of phenylethanolamine N-methyltransferase (PNMT) and N-methyl-d-aspartate type 1 receptor (NMDAR1), and down-regulation of gamma-Aminobutyric acid type A receptor (GABAAR), glutamate decarboxylase 1 (GAD 67), and glutamate decarboxylase 2 (GAD 65), respectively. Moreover, UCW considerably restored neurogenesis in the hippocampal regions which was disturbed by chronic restraint stress. CONCLUSIONS These results evidenced that UCW has pharmacological properties for brain protection and neurogenesis in status of stress-associated oxidative damage, and the underlying mechanisms involve the regulation of HPA axis in stress responses.

Abstract
Fever, which is closely linked to viraemia, is considered to be both the main and the earliest clinical sign in sheep infected with bluetongue virus (BTV). The aim of this study was to evaluate the potential use of infrared thermography (IRT) for early detection of fever in sheep experimentally infected with bluetongue virus serotype 1 (BTV-1) and serotype 8 (BTV-8). This would reduce animal stress during experimental assays and assist in the development of a screening method for the identification of fever in animals suspected of being infected with BTV. Rectal and infrared eye temperatures were collected before and after BTV inoculation. The two temperature measures were positively correlated (r=0.504, P<0.05). The highest correlation between rectal and infrared temperatures was observed when temperatures were above physiological levels. IRT discriminated between febrile and non-febrile sheep with a sensitivity of 85% and specificity of 97%. The results showed that eye temperature measured using IRT was a useful non-invasive method for the assessment of fever in sheep infected with BTV under experimental conditions. Further research is required to evaluate the use of IRT under field conditions to identify potentially infected animals in bluetongue surveillance programmes.

Abstract
OBJECTIVE To study the effect of moderate stress on corticotropin-releasing factor (CRF) components in the serotonergic midbrain region in a monkey model of functional hypothalamic amenorrhea. DESIGN After characterization of stress sensitivity, monkeys were moved to a novel room and given 20% less chow for 5 days before euthanasia. SETTING Primate research center. ANIMAL(S) Female cynomolgus macaques (Macaca fascicularis) characterized as highly stress resilient (HSR, n = 5), medium stress resilient (n = 4), or stress sensitive (SS, n = 4). INTERVENTION(S) Five days of diet in a novel room with unfamiliar conspecifics. MAIN OUTCOME MEASURE(S) Density of CRF axons in the serotonergic dorsal raphe nucleus; the number of urocortin 1 (UCN1) cells; the density of UCN1 axons; the expression of CRF receptor 1 (CRF-R1) and CRF-R2 in the dorsal raphe nucleus. RESULT(S) The CRF innervation was higher in HSR than in SS animals; UCN1 cell number was higher in HSR than in SS animals and UCN1 axon bouton density was not different; all opposite of nonstressed animals. The CRF-R1 was not different between the sensitivity groups, but CRF-R2 was higher in HSR than in SS animals. The relative expression of CRF-R1 and CRF-R2 was similar to nonstressed animals. CONCLUSION(S) The HSR animals respond to stress with an increase in CRF delivery to serotonin neurons. With stress, UCN1 transport decreases in HSR animals. The CRF receptor expression was similar with or without stress. These changes may contribute to resilience in HSR animals.

Myelophil attenuates brain oxidative damage by modulating the hypothalamus-pituitary-adrenal (HPA) axis in a chronic cold-stress mouse model. JOURNAL OF ETHNOPHARMACOLOGY 2013; 148:505-514. [PMID: 23665312 DOI: 10.1016/j.jep.2013.04.046] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/27/2012] [Revised: 04/12/2013] [Accepted: 04/23/2013] [Indexed: 06/02/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Myelophil is composed of Astragali Radix and Salviae Miltiorrhizae Radix, according to the long traditional pharmacological practices, and it has been used for patients with chronic fatigue-associated symptoms including concentration problem or memory loss. AIM OF THE STUDY This study aimed to evaluate the clinical relevance of Myelophil on brain oxidative damage using a chronic cold stress mice model. MATERIAL AND METHODS Balb/c mice were subjected to cold stress (4°C for 4h) six times per week for 2 weeks with or without oral administration of Myelophil (50, 100, or 200mg/kg), or ascorbic acid (50mg/kg). RESULTS Chronic cold stress induced histopathological hippocampal apoptosis with drastically increased serum levels of total reactive oxygen species and nitric oxide, as well as brain lipid peroxidation levels, protein carbonyl, and caspase-3/7 activity. These alterations were significantly ameliorated by Myelophil treatment. Myelophil administration significantly recovered the depleted glutathione and its enzymes, superoxide dismutase activity, and catalase protein and gene expression levels. Serum levels of corticosterone, dopamine, and adrenaline were notably altered by chronic cold stress but were significantly ameliorated by Myelophil treatment. Myelophil also normalized alterations in tumor necrosis factor-α, interleukin (IL)-1β, and IL-10 gene expression and protein levels. Chronic cold stress up-regulated gene expression levels of phenylethanolamine N-methyltransferase and monoamine oxidase-B, and glucocorticoid receptors in the hypothalamus and hippocampus, respectively, whereas Myelophil treatment completely normalized these levels. CONCLUSIONS These results suggest that Myelophil has potent pharmaceutical effects against chronic cold-stress-induced brain damage by relieving oxidative stress and inflammation and regulating stress hormones in mice.

[PMID: 23357537 PMCID: PMC3654014 DOI: 10.1016/j.pnpbp.2013.01.013] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2012] [Revised: 01/09/2013] [Accepted: 01/10/2013] [Indexed: 12/21/2022]
Abstract
Female cynomolgus monkeys exhibit different degrees of reproductive dysfunction with moderate metabolic and psychosocial stress. When stressed with a paradigm of relocation and diet for 60 days, or 2 menstrual cycles, highly stress resilient monkeys continue to ovulate during both stress cycles (HSR); medium stress resilient monkeys ovulate once (MSR) and stress sensitive monkeys do not ovulate for the entire 60 days (SS). This study examines serotonin-related gene expression in monkeys with different sensitivity to stress and exposed to 5 days of moderate stress. Monkeys were first characterized as HSR, MSR or SS. After resumption of menstrual cycles, each monkey was re-stressed for 5 days in the early follicular phase. The expression of 3 genes pivotal to serotonin neural function was assessed in the 3 groups of monkeys (n=4-5/group). Tryptophan hydroxylase 2 (TPH2), the serotonin reuptake transporter (SERT), and the 5HT1A autoreceptor mRNAs expression were determined at 4 morphological levels of the dorsal raphe nucleus with in situ hybridization (ISH) using digoxigenin-incorporated riboprobes. In addition, cFos was examined with immunohistochemistry. Positive pixel area and/or cell number were measured. All data were analyzed with ANOVA (3 groups) and with a t-test (2 groups). After 5 days of stress, TPH2, SERT, 5HT1A and cFos were significantly lower in the SS group than the HSR group (p<0.05, all). This pattern of expression was the same as the pattern observed in the absence of stress in previous studies. Therefore, the ratio of the HSR/SS expression of each serotonergic gene was calculated in the presence and absence of stress. There was little or no difference in the ratio of HSR/SS gene expression in the presence or absence of stress. Moreover, cFos expression indicates that overall, cell activation in the dorsal raphe nucleus and periaquaductal gray is lower in SS than HSR animals. These data suggest that the serotonin system may set the sensitivity or resilience of the individual, but serotonin-related gene expression may not rapidly respond to moderate stress in nonhuman primates.

Abstract
Stress has long been known to increase susceptibility to health disorders. In 2009, American Psychological Association further established association of stress to serious health problems. However, a quantitative and accurate way to evaluate and estimate stress status of individuals is still a big challenge. It has been shown, in large animal models using cattle, that psychological stress can be quantified as well as disease susceptibility could be predicted through biomarker discovery. Taking cue from those studies, we have evaluated and estimated psychological stress level of individuals theoretically and validated experimentally. Various biomarkers have also been identified which can be associated to psychological stress to predict stress status of unknown individuals.
