(1985)Phenylhydrazine is a hemolytic agent whose mechanism of action is related with the formation of free radicals and the induction of lipid peroxidation. The flavonoid silybin dihemisuccinate is an antihepatotoxic principle ...
-
(1993)The effect of human chorionic gonadotropin (hCG) on intact Leydig cell phospholipid methylation was studied. Hormonal stimulation of rat Leydig cells increased the incorporation of[methyl-3H]methionine into phospholipids ...
-
(Universidad de Chile, 1995)Se estudia a familias jóvenes pobres para detectar cual es el grupo más vulnerable respecto a la vivienda. La muestra estuvo formada por 100 familias jóvenes de Peñalolén. Cincuenta de nivel socio económico (NSE) muy bajo ...

(1995)Bone mineralization of adolescents that suffered of early postnatal u n d ern u tritio n . The bone mineralization o f 6 male and 18 female adolescents with a mean age o f 12 years and 11 months, who had suffered severe, ...
-
(Stockton Press, 1996)Approximately 70% of patients with prostate cancer develop bone metastases in the advanced state of the disease. In the present study, we sought to test the hypothesis that prostatic cancer cells produce factors that ...
-
(WILEY-LISS, DIV JOHN WILEY & SONS INC, 1996-04)Bone metastasis is a common event and a major cause of morbidity in prostate cancer patients. After colonization of bone, prostate cells induce an osteoblastic reaction which is not associated with marrow fibrosis ...
-
(1998)We investigated the effects of the drug 14-keto-stypodiol diacetate (SDA) extracted from the seaweed product Stypopodium flabelliforme, in inhibiting the cell growth and tumor invasive behavior of DU-145 human prostate ...
-
(Wiley-Liss, Inc., 1999)Transforming growth factor b1(TGF-b1) is a stimulator of malignant progression in mouse skin carcinogenesis. TGF-b1 exerts a differential effect on cultured nontumorigenic (MCA3D cell line) and transformed (PDV cell line) ...
-
BONE EXTRACELLULAR MATRIX STIMULATES INVASIVENESS OF ESTROGEN-RESPONSIVE HUMAN MAMMARY MCF-7 CELLS (WILEY-LISS, DIV JOHN WILEY & SONS INC, 1999-10-08)Bone is the most frequent site of metastasis in breast cancer. This causes destructive osteolytic lesions. To achieve metastasis to bone, breast cancer cells must proliferate in a new microenvironment, arrest on ...
-
(Wiley-Liss, 2000)Mesenchymal stem cells (MSCs), precursor cells resident in the bone marrow, have the capacity to differentiate into bone, cartilage, fat, and connective tissue. We have recently reported that MSCs from "healthy" donors ...
-
(2000-11)Objective: Aging is associated with increased risk of developing anemia and micronutrient deficiencies. Wheat-based staple foods are iron fortified in Chile. We aimed to establish the prevalence and etiology of anemia in ...
-
(Elsevier Science Inc., 2002)OBJECTIVE: We assessed the association between Gln27Glu and Trp64Arg genetic polymorphisms of the 2 (ADRB2) and 3 (ADRB3) adrenergic receptor genes with body mass index and other cardiovascular risk factors. METHODS: ...
-
(Mosby Elsevier, 2002)We evaluated bone mineral density, vitamin D status, and biochemical markers of bone turnover in seven children with epidermolysis bullosa (EB). Four had osteopenia (Z score, -1.5) and four 25(OH) vitamin D <34 nmol/L ...
-
(2002)Complete achromatopsia is genetically heterogeneous and segregates with mutations in CNGA3 or CNGB3 genes, which respectively encode for α- and β-subunits of the cyclic-nucleotide-gated (CNG) cation channel expressed in ...
-
(AMER OIL CHEMISTS SOC A O C S PRESS, 2002-04)Peroxisomal proliferator-activated receptors (PPAR) are a FA-response system involved in diverse cellular responses. FA regulate PPAR activity and modulate PPAR mRNA abundance. Increasing evidence indicates that PUFA are ...
-
(Elsevier Science B.V. on behalf of the Federation of European Biochemical Societies., 2002-04-18)We have examined the effect of transforming growth factor L1 (TGF-L1) and overexpression of the Smad4 gene on the phenotype of Car C, a ras mutated highly malignant spindle carcinoma cell line. TGF-L1-treated Car C cells ...
-
(Elsevier Science (USA), 2002-07-15)Mouse transformed keratinocytes cultured in the presence of transforming growth factor-b1 (TGF-b1) acquire a set ofmorphological and functional properties giving rise to a more motile phenotype that expresses mesenchymal ...
