Assessment of Changes in Body Composition During the First Postoperative Year After Bariatric Surgery.

Background: The potential effect of bariatric surgery on weight reduction and improvement of associated comorbidities is known, but the ratio obtained between the components of body weight, including lean body mass, body fat mass, and bone mass, is still not determined. This study aims to verify the changes in body composition during the first year after bariatric surgery.

Methods: We conducted a prospective observational cohort study.

Surgical treatment of tongue lymphangioma in a pediatric patient: a case report.

Lymphangiomas are benign tumors that occur predominantly in the head and neck regions. They are very common in children and are usually diagnosed at birth or during the first years of life. Understanding their clinical features is crucial to an early diagnosis.

Characterization of three human sec14p-like proteins: alpha-tocopherol transport activity and expression pattern in tissues.

Three closely related human sec14p-like proteins (hTAP1, 2, and 3, or SEC14L2, 3, and 4, respectively) have been described. These proteins may participate in intracellular lipid transport (phospholipids, squalene, tocopherol analogues and derivatives) or influence regulatory lipid-dependent events. Here, we show that the three recombinant hTAP proteins associate with the Golgi apparatus and mitochondria, and enhance the in vitro transport of radioactively labeled alpha-tocopherol to mitochondria in the same order of magnitude as the human alpha-tocopherol transfer protein (alpha-TTP).

Applied mechanics of the Puricelli osteotomy: a linear elastic analysis with the finite element method.

Background: Surgical orthopedic treatment of the mandible depends on the development of techniques resulting in adequate healing processes. In a new technical and conceptual alternative recently introduced by Puricelli, osteotomy is performed in a more distal region, next to the mental foramen. The method results in an increased area of bone contact, resulting in larger sliding rates among bone segments.
