Isoflurane increases the activity of the vascular matrix metalloproteinase-2 in non-pregnant rats and increases the nitric oxide metabolites in pregnancy.

Surgeries that require general anesthesia occur in 1.5-2% of gestations. Isoflurane is frequently used because of its lower possibility of affecting fetal growth.

Probiotic fermented whey-milk beverages: Effect of different probiotic strains on the physicochemical characteristics, biological activity, and bioactive peptides.

The effect of probiotic strains (Lactobacillus acidophilus La-03 (La-03); Lactobacillus acidophilus La-05 (La-05); Bifidobacterium Bb-12 (Bb-12) or Lacticaseibacillus casei-01 (L. casei-01)) on the characteristics of fermented whey-milk beverages during storage (4 °C, 30 days) was evaluated. The products were assessed for biological and antioxidant activities, physicochemical characteristics, and bioactive peptides.

Phase II consolidation trial with anti-Lewis-Y monoclonal antibody (hu3S193) in platinum-sensitive ovarian cancer after a second remission.

Objective: To investigate the efficacy and safety of hu3S193, a humanized anti-Lewis-Y monoclonal antibody, as a consolidation strategy in patients with platinum-sensitive recurrent epithelial ovarian cancer who achieved a second complete response after salvage platinum-doublet chemotherapy.

Methods: This single-arm phase II study accrued patients with recurrent epithelial ovarian cancer with Lewis-Y expression by immunohistochemistry who had achieved a second complete response after five to eight cycles of platinum-based chemotherapy. Patients received intravenous infusions of hu3S193, 30 mg/m every 2 weeks starting no more than 8 weeks after the last dose of chemotherapy and continuing for 12 doses, until disease progression, or unacceptable toxicity.

Antiproliferative and apoptotic effects of probiotic whey dairy beverages in human prostate cell lines.

The present study aimed to evaluate the antiproliferative and apoptotic effects of probiotic whey dairy beverages in human prostate cancer cell lines (PC-3 and DU-145). Five different whey beverages were manufactured: conventional whey beverage (without addition of probiotic strain, CTL); and whey beverages containing Lactobacillus acidophilus La-05, Lactobacillus acidophilus La-03, Lactobacillus casei-01, and Bifidobacterium animalis Bb-12. Cell viability was determined by MTT assay and cell cycle arrest, and apoptosis by flow cytometry.

Iron supplementation in pregnancy and breastfeeding and iron, copper and zinc status of lactating women from a human milk bank.

This study evaluated the influence of iron supplementation in pregnancy and breastfeeding on iron status of lactating women from a Brazilian Human Milk Bank. Blood and mature breast milk samples were collected from 145 women for assessment of iron status, as well as copper and zinc status. Haemoglobin, serum iron and ferritin were determined, respectively, by electronic counting, colorimetry and chemiluminescence.

Iron concentrations in breast milk and selected maternal factors of human milk bank donors.

The aim of this study was to evaluate the relationship between iron concentration in mature breast milk and characteristics of 136 donors of a Brazilian milk bank. Iron, vitamin A, zinc, and copper concentrations were assessed in human milk and maternal blood. Data were collected on maternal anthropometrics, obstetric, socioeconomic, demographic, and lifestyle factors.

Transcriptome characterization of human mammary cell lines expressing different levels of ERBB2 by serial analysis of gene expression.

Over-expression of ERBB2, a member of the family of transmembrane receptor tyrosine kinases, occurs in 15-30% of primary breast tumors and is associated with poor prognosis and chemoresistance to a variety of anticancer drugs. In this study, aiming to identify differentially-expressed genes involved in erbB2-mediated transformation of the breast, we generated SAGE libraries from two human mammary cell lines, derived from normal luminal cells, expressing different levels of erbB2. The parental cell line HB4a expresses basal levels and the C5.

Androgen receptor CAG repeat polymorphism in prostate cancer from a Brazilian population.

Shorter CAG repeats in the androgen receptor (AR) gene have been associated with increased prostate cancer risk. Aiming to investigate whether the AR CAG polymorphism is associated with an increased relative risk for prostate cancer in our population, genomic DNA from 133 prostate cancer patients and 279 healthy men controls were examined. We found no association between the AR CAG polymorphism and the relative risk of prostate cancer in white Brazilian individuals with a CAG repeat length View Article and Find Full Text PDF

Porphobilmogen deaminase gene mutations in Brazilian acute intermittent porphyria patients.

Acute intermittent porphyria (AIP) is an autosomal dominant disorder resulting from porphobilmogen deaminase (PBGD) deficiency. Seven unrelated Brazilian patients were investigated regarding PBGD gene mutations by polymerase chain reaction (PCR) and single strand conformation polymorphism (SSCP) analysis followed by direct DNA sequencing. The PBG gene screening disclosed abnormal SSCP patterns in exons 7, 9, 12, 13, and 15, as well as in introns 3 and 10.
