Sphingomyelinase-induced domain shape relaxation driven by out-of-equilibrium changes of composition (Biophysical Society, 2009)Sphingomyelinase (SMase)-induced ceramide (Cer)-enriched domains in a lipid monolayer are shown to result from an out-of-equilibrium situation. This is induced by a change of composition caused by the enzymatic production ...

Which patients are suitable candidates for laparoscopic adrenalectomy with needlescopic instruments? (2009)Laparoscopic adrenalectomy has become the standard surgical procedure for benign adrenal tumors. The benefits of this type of surgery are reduced blood loss and postoperative pain, improved cosmetic outcomes and a reduced ...

(2009)Petrographic analysis and geochemical characterization studies were carried out on vitreous dacite and/or rhyodacite artefacts from Formative period archaeological sites in the upper Salado River Basin in the Atacama Desert, ...
-
(2009)Background: Marginal ulcer (MU) is an occasional complication after gastric bypass. We studied the incidence of this complication by a prospective routine endoscopic evaluation. 441 morbidly obese patients were studied ...

(2008)Patients with type 1 diabetes mellitus (T1DM) face an array of difficulties during puberty which tend to be more significant in females. Excessive weight and fat mass gain, deterioration of metabolic control, loss of height ...
-
(2009)Background: Gastric bypass surgery (GBP) is increasingly used as a treatment option in morbid obesity. Little is known about the effects of this surgery on bone mineral density (BMD) and the underlying mechanisms. To ...
-
(2009)Background and Objectives: Membrane type 1-matrix metalloproteinase (MT1-MMP) is a collagenolytic enzyme involved in connective tissue remodeling. In periodontal tissues, either cytokines or growth factors regulate the ...

Laparoscopic repair of renal artery aneurysm: A description of the technique and results in 2 cases (2008)Background and Purpose: Renal artery aneurysm is a rare occurrence. We report our experience in the management of 2 symptomatic renal artery aneurysms with laparoscopic approach. Material and Methods: Two patients, male ...
-
(2009)Neuroanatomical and functional asymmetries are universal features of the vertebrate CNS, but how asymmetry is generated is unknown. Here we show that zebrafish fgf8 mutants do not elaborate forebrain asymmetries, demonstrated ...
-
(2008)Purpose: Gastric cancer is a curable disease if diagnosed at early stage. However, most cases are diagnosed at advanced stage because of the lack of screening programs. Therefore, the identification of plasma biomarkers ...
-
(2002)Histoplasma capsulatum is a dysmorphic fungus that dwells on earth in specific geographic locations. Its presence is favored by the droppings of bird and bats. The human infection is caused by the inhalation of a high ...
