É proposto um procedimento para a determinação direta de vanádio em amostras de urina por espectrometria de absorção atômica com atomização eletrotérmica em forno de grafite usando injeção à quente e pré-concentração dentro do tubo de grafite. Três aliquotas de 60 μL foram injetados seqüencialmente dentro do atomizador pré-aquecido a uma temperatura de 110 oC. As etapas de secagem e pirólise fo...

Objective: To describe the practice of laparoscopic surgery in the treatment of infertility at the Yaoundé Gyneco-Obstetrics and Pediatric Hospital. Materials and Methods: This was an observational study with retrolective data collection. All patients who underwent laparoscopy for infertility with a complete file were recruited. Data were collected on a pre-established form and analyzed with Mi...

Purpose:Genetic instability plays an important role in ovarian carcinogenesis. We investigated the level of telomere shortening and genomic instability in early andpreinvasive stages of ovarian cancer, serous tubal intraepithelial carcinoma (STIC), and tubo-ovarian dysplasia (TOD). Experimental Design: Fifty-one TOD from prophylactic salpingo-oophorectomies with BRCA1 or 2 mutation, 12 STICs, 5...

In developed countries, tuberculosis remains a health care challenge due to human immunodeficiency virus (HIV) and immigration from endemic regions. The Centers for Disease Control and Prevention reported 9557 new cases in 2015, with extrapulmonary involvement in 20.2% of the cases. We present a 33-year-old woman from Cape Town, South Africa, who developed abdominal pain and fever while working...

In the era of morphologic diagnostics, any epithelial tumor on or involving the ovaries was presumed to come from and be strictly of ovarian origin, apart from the rare but clearly metastatic tumors. Thus, many women who might have had small fallopian tube primary cancers that rapidly extended on to or into the ovary were deemed to have ovarian cancer. Now, as we begin to better understand that...

When CD4+ CD25+ regulatory T cells are depleted or inactivated for the purpose of enhancing antitumor immunity, the risk of autoimmune disease may be significantly elevated because these regulatory T cells control both antitumor immunity and autoimmunity. To evaluate the relative benefit and risk of modulating CD4+ CD25+ regulatory T cells, we established a new test system to measure simultaneo...
