Resiliency and Autonomic Control of Cardiac Responses to Stress
… (ER) is a trait that describes the ability to cope with stress, while effortful control (EC) is an individual difference related to the ability to optimally inhibit negative emotion through attentional mechanisms. ER has been linked to flexible cardiovascular responding without accounting …

Aquatic microbial community responses to stress: comparison of nontaxonomic and taxonomic indices
… <u>a</u>/Pheopigment (Chla/Pheo) were compared to the taxonomic measures of species diversity (d) and species richness as indicators of stress in aquatic environments. Field and laboratory microcosm responses of indigenous microbial communities exposed to municipal sewage treatment plant (STP) …

Analysis of Quantitative Electroencephalographic and Cardiovascular Responses to Stress Amoung Low- and High-Hostiles
This experiment was primarily designed to identify higher cortical correlates of cardiovascular arousal. Low- and high-hostile, right-handed, undergraduate men were identified using the Cook Medley Hostility Scale (CMHS). All participants (N = 30) completed the cold pressor paradigm. Cardiovascular …

PTSD Subtypes, Depressive Presentation, Dissociation, and Cognitive Appraisals and Their Impact on Cardiovascular Reactivity Responses to Stress
Both posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) are related to an increased risk for cardiovascular disease (CVD), with links to ischemic heart disease, myocardial infarction, cardiac mortality, and other cardiac conditions. Given that these disorders are associated …

The role of the catecholaminergic projections to the forebrain in the modulation of autonomic responses to stress
Exposure of animals to noxious or stressful stimuli increases heart rate (HR) and blood pressure through activation of the autonomic nervous system (ANS). Stressors also elicit the release of the neuromodulatory catecholamines dopamine (DA) and noradrenaline (NA) in several regions of the …

Socialization of coping with peer victimization and negative emotionality: Interactive contributions to children's responses to stress and depressive symptoms
… of coping and child negative emotionality to children’s responses to peer aggression and depressive symptoms. Children (n = 289, M age = 8.00, SD = .37) and their parents completed questionnaires at two waves over a one-year period. Results revealed that active socialization of coping …

A Comparison of Coping Responses to Stress Among Counselor Education Students at the Beginning Stage, Practicum Stage, and Graduating Stage from their Program of Studies
The purpose of this study was to determine if there is a difference in coping responses to stress among students in a Master's level counselor education program. The study was an investigation of the difference between three nonequivalent groups: Group A- Beginning counseling students, Group B- …

The Association Between Exposure to Poverty and Anxiety in Middle Childhood: Examination of the Modulating Roles of Coping, Responses to Stress, and Threat Bias Neural Activity
… in poverty since birth and self-reported symptoms of anxiety in middle childhood. Several models were tested with consideration to the potential modulating roles of coping strategies, responses to stress, and threat bias neural functioning. Exposure to poverty is associated with increased risk …

Reciprocal associations between youth's responses to interpersonal stress and depression: the moderating role of sex
… study examined reciprocal associations between responses to interpersonal stress and depression in youth. Specifically, it tested the hypothesis that depression predicts fewer effortful, planful responses to peer stress and more involuntary, dysregulated responses over time, and that these types …

Molecular Characterization of Stress Response in Western Honey Bee (Apis mellifera)
… ecosystems. However, they face various stressors such as pesticides, pathogens, habitat loss, and climate change. Extensive research has been conducted to understand how bees respond to these stressors. Scientists have discovered that honey bees exhibit complex physiological and …

Characterisation of stress responses in Lactobacillus paracasei and Bifidobacterium animalis (syn. lactis)
… thesis describes a study of the nature of the responses to stress, particularly acid stress, in Lactobacillus paracasei and Bifidobacterium anitnalis (syn. lactis). The aims of the study were validate the identification of the bacteria being studied, to determine the nature of their stress …

The glucocorticoid receptor plays a central role in mammalian reproduction and signal integration in pituitary gonadotropes
… modulation between the glucocorticoid receptor (GR) and gonadotropin-releasing hormone (GnRH) signalling pathways is a potential mechanism for integrating cellular responses to stress with reproductive function. This study investigated if membrane rafts play a role in GR and GnRH receptor …

Neurochemical Changes Following Stroke: Role In Neuroprotection And Cardiac Susceptibility
… changes were assessed 5 days after localized excitotoxic lesion of the IC or primary somatosensory cortex (SSC-I). Damage to the IC but not SSC-I reproduced the ipsilateral neurochemical changes of MCAO. Nevertheless, damage to the SSC-I produced local increases in NPY. Saline injection was …

Effects of nicotine on content of corticotropin releasing factor (CRF) in rat amygdala, hypothalamus and brain stem
Effects of 1.0 mg/kg and 0.4 mg/kg intraperitoneal nicotine on hypothalamic and extra hypothalamic levels of corticotropin releasing factor (CRF) were examined in 104 rats. CRF, a 41-amino acid peptide involved in responses to stress, fear and anxiety, influences the same neurotransmitter systems …

The Stress Is Unbearable, I Hope it Lasts: Case Studies in Reversal Theory
The relationship between stress and performance in sport is a central topic of investigation for sport psychology and has been quantitatively explored in depth over the last 3 decades. The ability to cope effectively with stress is suggested to be one of the most important determinants in athletic …
