[Management of psychological trauma in primary care].

Exposure to traumatic events is frequent in the general population and psychiatric sequelae such as post-traumatic stress disorders are common. The symptoms of psychiatric sequelae after trauma are vague, with multiple psychological and physical symptoms, which can confuse the health care professional. This paper seeks to facilitate the work in primary care, providing practical information about the diagnosis, initial management and referral of patients who have suffered traumatic experiences.

A microwave interferometer for small and tenuous plasma density measurements.

The non-intrusive density measurement of the thin plasma produced by a mini-helicon space thruster (HPH.com project) is a challenge, due to the broad density range (between 10(16) m(-3) and 10(19) m(-3)) and the small size of the plasma source (2 cm of diameter). A microwave interferometer has been developed for this purpose.

Effect of losartan on early liver fibrosis development in a rat model of nonalcoholic steatohepatitis.

Background And Aim: Nonalcoholic steatohepatitis (NASH) is a metabolic disorder of the liver that may evolve into fibrosis or cirrhosis. Recent studies have shown reduction of experimental liver fibrosis with the use of angiotensin-converting-enzyme inhibitors or angiotensin-receptor antagonists. The aim of this study was to determine whether losartan can influence the early phase of fibrogenesis in an animal model of NASH.

Pentoxifylline does not prevent neither liver damage nor early profibrogenic events in a rat model of non-alcoholic steatohepatitis.

Background: Non-alcoholic steatohepatitis (NASH) is a metabolic disorder of the liver, which may evolve to fibrosis or cirrhosis. Pentoxifylline (PTX) has been postulated to act as an antifibrogenic agent able to inhibit hepatic stellate cell proliferation and collagen synthesis in vitro. Short-term studies suggest beneficial effects of PTX in experimental models of NASH.
