As part of the Aircraft Carrier Alliance (ACA) platform design team, Rob Weedon has assumed the role of Chief Naval Architect and will be responsible for General Arrangement (GA), hydromechanics, shock, escape and transversal areas including whole-ship safety.A Chartered Engineer (CEng) and Member of the Royal Institution of Naval Architects (MRINA), Rob has worked on ship design aspects of the QEC project since 2001.Martin Hails who joined BMT in 1995 and has played an instrumental role in a variety of submarine and surface ship programmes, including previous roles on the QEC project, has accepted the position of Chief Systems Engineer. A Chartered Engineer and Fellow of the Institution of Mechanical Engineers (FIMechE), this role will see Martin take charge of aviation, fire safety, auxiliaries, outfit and furnishings, as well as mechanical systems.Roy Quilliam, Technical Director at BMT Defence Services comments: “As this project moves further into detail design and manufacture, there is an increasing need for deeper levels of technical understanding within the ACA platform design team. BMT is committed to supporting Thales UK in its role as an Alliance member and I am delighted that we are able to provide two highly experienced and competent specialists to fill these roles, reinforcing the strong calibre of people we have within the business. We’re confident that their deployment will be to the benefit of BMT, our partners and the overall programme moving forward.[mappress]Source: BMT, August 24, 2011; View post tag: secure View post tag: UK Back to overview,Home naval-today UK: BMT’s Naval Experts Secure Prominent Roles Within QEC Project Industry news August 24, 2011center_img View post tag: experts View post tag: Prominent View post tag: QEC View post tag: project View post tag: News by topic View post tag: BMT’s View post tag: within Share this articlelast_img read more

PTSD in women may have genetic link

CNN News Share Tweet After a single traumatic event, as many as one-fourth of people exposed will develop post-traumatic stress disorder, a psychiatric disorder characterized by anxiety, hyperarousal and persistent unwanted memories.Scientists are looking for genes or gene pathways that can help better predict PTSD. A new study in the journal Nature suggests one such route in women: through a protein called pituitary adenylate cyclase-activating polypeptide, which is known to regulate the cellular stress response. Women are more likely to have PTSD in general; 10% of women and 5% of men develop the condition sometime in their lives.Participants, of which there were more than 1,200, came from an impoverished area around Atlanta, Georgia, and did not have military-related trauma. Interpersonal violence, gunshot violence, sexual assaults and other abuse were some of the triggers of PTSD reported.Study results suggest that a particular gene variant for PACAP may be sensitive to both estrogen and stress, because it is associated with women who have PTSD.“It helps us to understand that PTSD is complex,” said Dr. Kerry Ressler of Emory University School of Medicine, lead study author. “There are many individual ways that people come to PTSD, in the same way that there are probably 100 different ways to come down with heart failure.”This is probably one of many biological pathways that lead to PTSD, he said. Understanding it will help get a better picture of the biology and the neural circuitry of PTSD, and could have implications for future diagnosis and treatment of the condition.Ressler’s group found that this gene variant is highly associated with all three subcategories of PTSD: hyperarousal, intrusive memories and avoidant behavior. It could be broadly linked to all of them, or perhaps the definition of PTSD is not specific enough to what’s going on biologically, Ressler said.In rodents, the parts of the brain associated with fear and stress alter the regulation of these genes with fear learning. This could be happening in humans also, he said.The gene variant described in the research influences the key human stress response system, which is central to PTSD and so it makes clinical sense that it would be involved, said Dr. John Markowitz, PTSD researcher at Columbia University College of Physicians and Surgeons, who is not a geneticist but offered his clinical perspective on the research.But, Markowitz cautioned, in an e-mail, “the history of psychiatric genetics is littered with findings subsequently retracted or not borne out.” This particular study, which he called an “elegant research report,” has results that apply only to an estrogen gene in chronically traumatized women.There is more work to be done to examine the roots of PTSD in men, and there may be other pathways involved in women with acute trauma, Markowitz said. Another next step would be to examine whether the results of this study are consistent in members of the military.
