Effectiveness of Mobile Technology in Managing Fatigue: Balert App.

The performance of professional tasks with a high cognitive, emotional, and even physiological demand, can cause a state of mental fatigue, which implies attentional alterations, greater errors in the tasks performed and a decrease in personal and work productivity caused by a deterioration of the cognitive control processes. The present study presents a mobile phone application named BAlert that allows monitoring and controlling the body's fatigue processes based on the scores obtained in the Stroop effect and the heart rate variability. A pilot study has been carried out with a sample of 63 adults who have used the application a total of 942 times.

Association of -765G>C polymorphism of the COX-2 gene with recurrent embryo implantation failure in Southern Chilean women.

Background: Embryo implantation failure is considered an important cause of infertility in women undergoing assisted reproductive protocols. Recent studies demonstrated that the cyclooxygenase-2 (COX-2) enzyme is implicated in biosynthesis of prostaglandins and play an important role in the molecular implantation mechanisms. According to this evidence, we evaluated the potential association between the -765G>C (rs20417) polymorphism at the COX-2 gene and the implantation failure susceptibility in a sample of Chilean women.
