Project description:Analysis of transcript abundance estimates as a function of child soldier status, PTSD symptoms, and psychological resilience. Gene expression profiling was conducted on dried blood spot (DBS) samples collected from community dwelling adolescents and young adults in Nepal. Approximatley half of the sample were former child soldiers in the Nepal People's War and the other half were demographically similiar civilian non-combatants. In addition to basic demographic characteristics (age, sex, ethnic minority status, social caste status, education level), participants were also assessed on syptoms of post-traumatic stress (PTS, assessed by a culturally adapted version of The Child PTSD Symptom Scale; Kohrt BA, et al. (2011) Validation of cross-cultural child mental health and psychosocial research instruments: adapting the Depression Self-Rating Scale and Child PTSD Symptom Scale in Nepal. BMC Psychiatry 11(1):e127, with higher values indicating greater PTSD symptoms) and psychological resilience (assessed by a culturally adapted version of the Resilience Scale; Wagnild GM & Young HM (1993) Development and psychometric evaluation of the Resilience Scale. Journal of Nursing Measurement, with higher values indicating greater resilience). Dichotomous variables were coded 0=no/absent and 1=yes/present. Valid gene expression data are available for 254 samples.

Project description:PTSD - Posttraumatic stress disorder. 33 samples taken from PMBCs of survivors of psychological trauma, in two time points: in ER, few hours after the truma, and four months later. Some of the patients devepled chronic PTSD (17 samples) and others recovered and set to be the Control group (16 samples). This is the normalized active genes: 4512 probes from U95A chip. The raw data is available in series GSE845. Samples are labeled with 3 tags: P/C for PTSD or Control, ER/M4 - for time point of sample, D/ND for Decrement or Non-decrement symptoms over time. (e.g. sample 23C-M4-D-Norm was taken 4 months after trauma from patient 23 which belongs to the control group and showed decrease in symptoms) . Samples include the expression value, the GeneBank accession number and Affymetrix indication of valid calls.

Project description:Probiotics may alter stress sensitivity by modulating the gut-brain axis. The heat-inactivated, enteric-colonizing Lactobacillus gasseri, CP2305 (paraprobiotic CP2305), has been shown to ameliorate psychological stress-related symptoms. This study was designed to reveal the beneficial effects of paraprobiotic CP2305 on top athletes experiencing physical and mental stresses.

Project description:Military service members often return from deployment with a multiplicity of injuries, including mild traumatic brain injury, depression, and sleep disorders, which obsures diagnosis of PTSD symptoms and complicates treatment of PTSD. In order to understand the biological mechanisms underlying PTSD, gene expression profiles of military service members with and without PTSD were compared. Additionally, gene expression was examined based on intrusion symptoms, a distinct subtype of PTSD symptoms, and on improvement of PTSD symptoms at a three month follow up. RNA was extracted from blood samples and hybridized to the HG-U133_Plus_2 Affymetrix chip.

Project description:<p>The Genomic Predictors of Combat Stress Vulnerability and Resilience Study was designed to probe the likely hereditary basis for risk or resilience to develop PTSD and other trauma spectrum disorders. The overall guiding hypothesis was that genomic variation gives rise to risk/susceptibility traits that, when actuated by traumatic environmental stimuli, such as combat, give rise to PTSD and other stress-related phenotypes.</p> <p>Two studies designed to identify risk and resilience factors for combat-induced, stress-related symptoms are being conducted by our group: The Marine Resiliency Study (MRS) is a prospective PTSD study with longitudinal follow-up (pre- and post-exposure to combat stress) of US Marines bound for deployment to Iraq or Afghanistan. Extensive phenotyping includes 3 domains: Psychosocial, Psychophysiologic, and Biophysiologic. The biological and physiological measures collected were chosen in part due to their potential to serve as intermediate phenotypes for stress-related disorders. A second, cross-sectional study involves a cohort of combat-exposed active duty or previously deployed service members (CAVC), including PTSD cases and controls with comparable psychosocial and clinical phenotypes.</p> <p>Little information is available about the factors that explain why some trauma survivors develop stress disorders and some do not. It is hoped that the insights gained from this approach will improve understanding of the genetic contributors to PTSD, and potentially provide novel diagnostic tests and therapeutic approaches to this currently enigmatic and difficult-to-manage condition.</p>

Project description:Gene expression profiling was carried out on primary ovarian carcinomas from 10 patients. The primary research question is whether gene expression differs in tissues from individuals with high vs low symptoms of psychological depression. Experiment Overall Design: Gene expression profiling was carried out on primary ovarian carcinomas from 10 patients. The primary research question is whether gene expression differs in tissues from individuals with high vs low symptoms of psychological depression.
