Ashley N Edes, Douglas E Crews
Multiple stressors affect developing and adult organisms, thereby partly structuring their phenotypes. Determining how stressors influence health, well-being, and longevity in human and nonhuman primate populations are major foci within biological anthropology. Although much effort has been devoted to examining responses to multiple environmental and sociocultural stressors, no holistic metric to measure stress-related physiological dysfunction has been widely applied within biological anthropology. Researchers from disciplines outside anthropology are using allostatic load indices (ALIs) to estimate such dysregulation and examine life-long outcomes of stressor exposures, including morbidity and mortality...

BACKGROUND: Heat stress as a physical harmful agent can increase the risk of health and safety problems in different workplaces such as mining. Although there are different indices to assess the heat stress imposed on workers, choosing the best index for a specific workplace is so important. Since various criteria affect an index applicability, extracting the most effective ones and determining their weights help to prioritize the existing indices and select the optimal index. METHODS: In order to achieve this aim, present study compared some heat stress indices using effective methods...

Cadmium (Cd) is a persistent environmental and occupational contaminant that accumulates in the liver and induces oxidative stress and inflammation. Melatonin possesses potent hepatoprotective properties against the development and progression of acute and chronic liver injury. Nevertheless, the molecular mechanism underlying the protective effects of melatonin against Cd-induced hepatotoxicity remains obscure. In the present study, we aimed to investigate the effects of melatonin on Cd-induced liver inflammation and hepatocyte death...

Nociceptin/Orphanin FQ (N/OFQ) is a 17 amino acid peptide whose receptor is designated ORL1 or nociceptin receptor (NOP). We utilized a potent, selective, and orally bioavailable antagonist with documented engagement with NOP receptors in vivo to assess antidepressant- and anxiolytic-related pharmacological effects of NOP receptor blockade along with measures of cognitive and motor impingement. LY2940094 ([2-[4-[(2-chloro-4,4-difluoro-spiro[5H-thieno[2,3-c]pyran-7,4'-piperidine]-1'-yl)methyl]-3-methyl-pyrazol-1-yl]-3-pyridyl]methanol) displayed antidepressant-like behavioral effects in the forced-swim test in mice, an effect absent in NOP (-/-) mice...

This study was conducted to investigate the associations among work-related musculoskeletal disorders (WMSDs), job stress, and job attitude of occupational therapists in South Korea. Self-reporting questionnaires were distributed to 150 occupational therapists. Of the 128 occupational therapists who responded, 110 (85.9%) reported WMSDs affecting at least one body site. The most affected WMSDs site was the low back (26.8%), and the most reported number of body site affected by WMSDs was one (53.9%). As a result, there were significant differences in job stress and job attitude depending on the age, work experience, working hour, presence or absence of WMSDs, and number of site of pain...

The tumour suppressor p53 is a transcription factor that controls cellular stress responses. Here, we dissected the transcriptional programmes triggered upon restoration of p53 in Myc-driven lymphomas, based on the integrated analysis of p53 genomic occupancy and gene regulation. p53 binding sites were identified at promoters and enhancers, both characterized by the pre-existence of active chromatin marks. Only a small fraction of these sites showed the 20 base-pair p53 consensus motif, suggesting that p53 recruitment to genomic DNA was primarily mediated through protein-protein interactions in a chromatin context...

Paraquat (PQ) is a nonselective bipyridyl herbicide widely used in agriculture to control weeds, but its accidental, occupational, or intentional exposure in humans is known to cause pneumo- and neurotoxicity which may proves fatal. Oxidative stress is reported as an underlined mechanism of PQ-induced toxicity in alveolar cells, neurons, and astroglia. PQ generates superoxides both through electron transport reaction (ETC) with nicotinamide adenine dinucleotide-dependent oxidoreductase and by the redox cycling via reaction with molecular oxygen...

BACKGROUND: Psychosocial factors have been shown to predict a poor disease course in patients with inflammatory bowel disease (IBD), but whether this applies to job stress is currently unknown. We assessed the prevalence of job stress and its correlates in a large cohort of patients with IBD. METHODS: We included all adult, professionally active patients enrolled between 2006 and 2015 in the Swiss IBD Cohort. Job stress was measured through the self-report effort-reward imbalance ratio and overcommitment (OC) to work questionnaires...

STUDY QUESTION: What are some of the challenges of working in a fertility clinic? SUMMARY ANSWER: The most frequently mentioned challenges were workload (e.g. high time pressure) and patient-related sources (e.g. unrealistic expectations). WHAT IS KNOWN ALREADY: One study showed a too high workload, worry about handling human material and low success rates were main stressors in fertility clinics. STUDY DESIGN, SIZE, DURATION: An online open-ended survey inviting participants to respond to seven questions was distributed to 5902 members of the European Society for Human Reproduction and Embryology (ESHRE, October 2010)...

BACKGROUND: Research indicate that social class mobility could be potentially important for health, but whether this is due to the movement itself or a result of people having been integrated in different class contexts is, to date, difficult to infer. In addition, although several theories suggest that transitions between classes in the social hierarchy can be stressful experiences, few studies have empirically examined whether such movements may have health effects, over and above the implications of "being" in these classes...

We investigated the prevalence of smoking and factors associated with smoking in infertile Korean women. Smoking status, education, occupation, personal habits, past medical history, current illness, stress level, and menstrual characteristics were collected from self-report questionnaires. The Beck Depression Inventory (BDI) was used to assess the degree of depression. Data on the causes of infertility and levels of six reproductive hormones were collected from medical records. Among 785 women less than 42 years of age, the prevalence of current, secondhand, past, and never smokers were 12...
