REVIEW
Marin Kautz, Dennis S Charney, James W Murrough
Resilience to traumatic stress is a complex psychobiological process that protects individuals from developing posttraumatic stress disorder (PTSD) or other untoward consequences of exposure to extreme stress, including depression. Progress in translational research points toward the neuropeptide Y (NPY) system - among others - as a key mediator of stress response and as a potential therapeutic focus for PTSD. Substantial preclinical evidence supports the role of NPY in the modulation of stress response and in the regulation of anxiety in animal models...

Contemporary theory suggests that prefrontal cortex (PFC) function is associated with individual variability in the psychobiology of the stress response. Advancing our understanding of this complex biobehavioral pathway has potential to provide insight into processes that determine individual differences in stress susceptibility. The present study used functional magnetic resonance imaging to examine brain activity during a variation of the Montreal Imaging Stress Task (MIST) in 53 young adults. Salivary cortisol was assessed as an index of the stress response, trait anxiety was assessed as an index of an individual's disposition toward negative affectivity, and self-reported stress was assessed as an index of an individual's subjective psychological experience...

Differences in aggressive behavior could be partially explained by differential prenatal exposure to testosterone (T). A peripheral marker of prenatal T exposure is the 2D:4D ratio, which has shown a negative correlation with self-reported aggression in violent men. This study tested the direct association of the 2D:4D ratio with anger expression and the risk of recidivism in intimate partner violence (IPV) perpetrators after psychotherapeutic intervention program. The sample consisted of IPV perpetrators, whose 2D:4D ratio was measured before the intervention...

Several studies have demonstrated that women show a greater interest for social information and empathic attitude than men. This article reviews studies on sex differences in the brain, with particular reference to how males and females process faces and facial expressions, social interactions, pain of others, infant faces, faces in things (pareidolia phenomenon), opposite-sex faces, humans vs. landscapes, incongruent behavior, motor actions, biological motion, erotic pictures, and emotional information. Sex differences in oxytocin-based attachment response and emotional memory are also mentioned...

OBJECTIVES: Understanding individual differences in the psychobiology of the stress response is critical to grasping how psychosocial factors contribute to racial and ethnic health disparities. However, the ways in which environmentally sensitive biological systems coordinate in response to acute stress is not well understood. We used a social-evaluative stress task to investigate coordination among the autonomic nervous system, hypothalamic-pituitary-adrenal axis, and immune/inflammatory system in a community sample of 85 healthy African American men and women...

Early adverse experiences can precede long-term negative effects on physical health. Children experiencing armed conflict, flight and displacement, and refugee life may be at enhanced risk. Recent psychobiological models integrating knowledge about perinatal and childhood stress with susceptibility to chronic illnesses in later life make clear the pressing need for protective provision for war-affected children, who experience multiple traumas and continuing stressors. There is increasing recognition of the mechanisms linking physical and mental health with adult diseases seen as developmental disorders with origins early in life...

Partnered fathers often have lower testosterone than single non-parents, which is theorized to relate to elevated testosterone (T) facilitating competitive behaviors and lower T contributing to nurturing. Cultural- and individual-factors moderate the expression of such psychobiological profiles. Less is known about genetic variation's role in individual psychobiological responses to partnering and fathering, particularly as related to T. We examined the exon 1 CAG (polyglutamine) repeat (CAGn) within the androgen receptor (AR) gene...

William Horsley Gantt is well known as one to the principal proponents of Pavlovian methodology in the U.S. After a long stay at Ivan Petrovich Pavlov's laboratory in Leningrad from 1925 to 1929, Gantt was invited by Adolf Meyer to join the Henry Phipps Psychiatric Clinic, where he founded and directed the Pavlovian Laboratory from 1930 to 1964. Soon after his arrival at Phipps Clinic in 1931, Gantt began a Pavlovian research program that included the investigation of nervous disturbances in dogs and clinical researches with psychiatric patients...

Cardiovascular events and emotional disorders share a common epidemiology, thus suggesting fundamental pathways linking these different diseases. Growing evidence in the literature highlights the influence of psychological determinants in somatic diseases. A patient's socio-economic aspects, personality traits, health behavior and even biological pathways may contribute to the course of cardiovascular disease. Cardiac events often occur suddenly and the episode can be traumatic for people not prepared for such an event...

PURPOSE OF REVIEW: It was first proposed in the late 1990s that objective markers of sleep disturbance could serve as an index of the biological severity of insomnia. In 2013, a heuristic model of two insomnia phenotypes based on objective sleep duration was proposed. Herein, we review the studies conducted in the past 3 years on the insomnia with short sleep duration phenotype and its implications for a clinical research agenda. RECENT FINDINGS: Studies have shown that insomnia with objective short sleep duration is associated with physiologic hyperarousal and cardiometabolic and neurocognitive morbidity, whereas insomnia with normal sleep duration is not...

'Reward sensitivity' explains inter-individual differences in the motivation to obtain rewards when reward cues are perceived. This psychobiological trait has been linked to higher consumption of palatable food when exposed to palatable food cues. The current study aims to examine if reward sensitivity explains differences in patterns of fat and lean tissue accretion over time in children. A longitudinal observational study with measurement waves in 2011 (baseline), 2012, 2013, and 2015 was conducted. The sample was a population-based Flemish cohort of children (n = 446, 50% boys and 5...

Dispositional negativity-the propensity to experience and express more frequent, intense, or enduring negative affect-is a fundamental dimension of childhood temperament and adult personality. Elevated levels of dispositional negativity can have profound consequences for health, wealth, and happiness, drawing the attention of clinicians, researchers, and policymakers. Here, we highlight recent advances in our understanding of the psychological and neurobiological processes linking stable individual differences in dispositional negativity to momentary emotional states...

Cannabis is one of the earliest cultivated plants. Cannabis of industrial utility and culinary value is generally termed as hemp. Conversely, cannabis that is bred for medical, spiritual and recreational purposes is called marijuana. The female marijuana plant produces a significant quantity of bio- and psychoactive phytocannabinoids, which regained the spotlight with the discovery of the endocannabinoid system of the animals in the early 90's. Nevertheless, marijuana is surrounded by controversies, debates and misconceptions related to its taxonomic classification, forensic identification, medical potential, legalization and its long-term health consequences...

CONTEXT: To date, there are few studies investigating the impact of body changes induced by cross-sex hormonal treatment (CHT) on psychobiological well-being in gender-dysphoric persons (GDs). OBJECTIVE: The objective of the study was to assess whether CHT-related body changes affect psychobiological well-being in GDs. METHODS: A consecutive series of 359 GDs was considered for a cross-sectional section of the study. In addition, 54 GDs were studied in a 2-year follow-up...

This is the first report of the psychobiology of stress in BASE jumpers, one of the most dangerous forms of extreme sport. We tested the hypotheses that indicators of emotional style (temperament) predict salivary cortisol reactivity, whereas indicators of intentional goal-setting (persistence and character) predict salivary alpha-amylase reactivity during BASE jumping. Ninety-eight subjects completed the Temperament and Character Inventory (TCI) the day before the jump, and 77 also gave salivary samples at baseline, pre-jump on the bridge over the New River Gorge, and post-jump upon landing...

We investigated effects of a brief (10.5 min) cognitively demanding task on graded exercise test performance. Untrained, university students (N = 15) completed two graded exercise tests in counterbalanced, randomised order. One test was preceded by restful viewing of a documentary video (control); the other by a stop-signal task. Cardiorespiratory functions and perceived exertion were monitored during exercise. Peak power output (W) was lower following the stop-signal task (M = 240.03, SD = 53.37) compared to control (M = 246...

Most research into 3,4-methylenedioxymethamphetamine (MDMA) has debated its psychobiological effects in relation to neurotransmission. This article debates the contributory roles of the neurohormones oxytocin and cortisol for their psychobiological effects in humans. The empirical literature on these neurohormones is reviewed and suggestions for future research outlined. Acute MDMA or 'ecstasy' can generate increased levels of oxytocin and cortisol, and these neurohormonal changes may be important for its mood-enhancing and energy-activation effects in humans...

Diabetes mellitus is one of the most common causes of neuropathy. Although antioxidant and antidiabetic effects of the aqueous extract of purslane (Portulaca oleracea) (AEOP) have been demonstrated before by other researchers, we did not find any study that assessed the psychobiological effects of AEOP in diabetes induced animals. Thirty ovariectomized (OVX) female Wistar rats were randomly divided into 3 groups of control, Dia and Dia+AEOP. The latter group was orally treated by 300 mg/kg of AEOP for 35 days...
