(NORTH AMER ASSOC STUDY OBESITY, 2007-07)Objective: The ability to form new adipose cells is important to adipose tissue physiology; however, the mechanisms controlling the recruitment of adipocyte progenitors are poorly understood. A role for locally generated ...
-
(INT LIFE SCIENCES INST NORTH AMERICA, 2006-05)The essential fatty acids (EFAs), particularly the n-3 long-chain polyunsaturated fatty acids (LCPs), are important for brain development during both the fetal and postnatal period. They are also increasingly seen to be ...
-
(Sociedad Médica de Santiago, 2007-07)Functional limitations limit the independence and jeopardize the quality of life of elderly subjects. Aim: To assess the association between anthropometric measures and body composition with functional limitations in ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-10)Melatonin has been shown to inhibit long-term potentiation (LTP) in hippocampal slices of rats. Since LTP may be one of the main mechanisms by which memory traces are encoded and stored in the central nervous system, it ...
-
(AMER SOC BONE & MINERAL RES., 2004-10)There are disparate observations on central and peripheral effects of leptin, but several studies consistently support its role as a link between fat and bone. Bone marrow stroma contains mesenchymal stem cells (MSCs), ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-05-15)Mild reduction in the protein content in the diet of pregnant rats from 25 to 8% casein, calorically compensated by carbohydrates, does not alter body and brain weights of rat pups at birth, but results in significant ...
-
(INST GRASA SUS DERIVADOS, 2004-07)Cholesterol is a molecule with a double bond in its structure, and therefore it is susceptible to oxidation leading to the formation of oxysterols. These oxidation products are found in many commonly consumed foods and ...
-
(ELSEVIER, 2006-10-02)In this study we analyzed the role of the c-Jun N-terminal kinases (JNK) pathway in the TGF-beta 1 stimulation of urokinase-type plasminogen activator (uPA), initial stages of epithelial-mesenchymal transdifferentiation ...
-
(Sociedad Médica de Santiago, 2004-01)Type 1 diabetes (DM1) is caused by an autoimmune process that destroys beta cells of pancreas. Not all carriers of susceptible HLA genes and positive for autoantibodies develop the disease. Environmental factors play a ...
-
(ELSEVIER, 2006-06-01)Recently, we reported the presence of higher levels of metallothionein (MT) in placentas of smokers compared to non-smokers. In the present study, we designed experiments to separate and evaluate two isoforms of NIT (MT-1 ...
-
Adult hippocampus derived soluble factors induce a neuronal-like phenotype in mesenchymal stem cells (ELSEVIER, 2006-10-02)Bone marrow-derived mesenchymal stem cells (MSCs) are not restricted in their differentiation fate to cells of the mesenchymal lineage. They acquire a neural phenotype in vitro and in vivo after transplantation in the ...
-
(AMER SOC CLINICAL NUTRITION, 2006-10)Background: One of the strategies to control iron deficiency anemia is the fortification of food with iron. A mechanism for improving the bioavailability of iron is to add an iron absorption promoter. Objective: The ...
-
(SOC ENDOCRINOLOGY, 2006-12)Human mesenchymal stem cells (hMSCs) are multipotent cells present in bone marrow, which differentiate into osteoblasts and adipocytes, among other lineages. Oestrogens play a critical role in bone metabolism; its action ...
-
(BLACKWELL, 2006-08)Rats submitted to fetal growth retardation by in utero malnutrition develop hypertension when adult, showing increased hypothalamic mRNA expression for corticotropin-releasing hormone (CRH) and increased central noradrenergic ...
-
(ELSEVIER, 2006-02)A rare case of type I diabetes is studied in an Amerindian (Mapuche) family from Chile, analyzing glutamic acid decarboxylase, islet-cell autoantibodies and human leukocyte antigen (HLA) genes. The affected sib is the only ...
-
(SPRINGER, 2006-12)The aim of this study was to assess the frequency of fatty acid binding protein 2 (FABP2) Ala54Thr genetic polymorphism and to evaluate its association with obesity and insulin resistance in Chilean aboriginal populations. ...
-
(ELSEVIER, 2006-10)Copper is an essential micronutrient for life. It is required by a wide range of species, from bacteria to yeast, plants and mammals including humans. To prevent the consequences of the excess or deficit of copper, living ...
-
(ELSEVIER, 2006-01-05)The increasing recognition of the participation of free radical-mediated oxidative events in the initiation and/or progression of cardiovascular, tumoural, inflammatory and neurodegenerative disorders, has given rise to ...
-
(ELSEVIER IRELAND LTD, 2007-07)Objective: To evaluate the influence of ApaI, BsmI and TaqI polymorphisms of the VDR gene and HLA-DQB1* alleles in type 1 diabetic children and to assess their possible relationship with circulating levels of 25-hydroxyvitamin ...
-
(ELSEVIER SCIENCE BV, 2007-07)Nine hundred cases of seafood related diarrhea were reported in the region of Puerto Montt, Chile during the austral summer of 2006. This is the continuation of the large outbreaks associated with the consumption of seafood ...
