This paper shows two approaches developed by us where wireless sensors could find their position using WLAN technology. The scenario is an indoor environment that contains walls, interferences, multipath effect, humidity and temperature variations, etc., and both approaches are based

This was a descriptive study using the General Practice Research Database, a UK primary care database. A total of 16,746 women who, between July 1, 1999, and June 30, 2001, were prescribed either tibolone or one of the estrogen + progestogen regimens listed above were included. The main outcome measures were risk factors associated with endometrial cancer and breast cancer. The clinical background of women who were prescribed tibolone differed from that of women who were prescribed combination products. More frequently than expected, women who were most recently prescribed tibolone had a history of chronic breast disease, a personal history of breast cancer, or a history of (long-term) estrogen-only therapy. Furthermore, medical records of this group of women showed more frequent reports of hypertension and previous uterine procedures. This study confirms previous findings that in the United Kingdom, general practitioners seem to prescribe tibolone preferentially to women with increased risks of breast and endometrial cancer as compared with women who are prescribed estrogen + progestogen products.

In the presence of 40% acetonitrile, the alkaline protease from Bacillus lentus can catalyze the kinetic resolution of racemic ester 7 to afford (S)-acid 4 in 49% chemical yield/per cycle with 98%

The pioneer (early-succession) species (PS) were Cecropia

In order to verify this hypothesis, plants of Licopersicon esculentum L. cv. Santa Clara were submitted to sudden and slow

Trichobezoar is a rare condition seen almost exclusively in young women with trichotillomania and trichotillophagia. When not recognized, the trichobezoar continues to grow, which increases the risk of severe complications such as gastric ulceration and even perforation. Formation of a gallstone within the trichobezoar (tricholithobezoar) is an event that has not yet been described. We report the case of a 22-year-old woman admitted to the emergency room with signals and symptoms of an epigastric mass and perforative acute abdomen. Radiological study revealed bilateral pneumoperitoneum. Personal history revealed depressive syndrome, trichotillomania and trichophagia. With a diagnosis of visceral perforation, an urgent exploratory laparotomy was performed. This confirmed the diagnosis of gastric perforation due to a large trichobezoar with the formation of a gastrolith that was removed by anterior gastrotomy. Biochemical study of the gastric stone revealed that it was composed of bile salts. There were no complications. The patient was discharged on the 5th postoperative day and was referred for psychiatric treatment.
