Positive effects of zinc supplementation on growth, GH, IGF1, and IGFBP3 in eutrophic children
(WALTER DE GRUYTER & COBERLIN, 2012)
Zinc is an essential micronutrient for growth and development. Its deficiency causes growth retardation in children and adolescents. The present study analyzes the effect of zinc on growth hormone (GH) secretion, insulin-like ...
Distinct mechanisms underlie adaptation of proximal tubule Na+/H+ exchanger isoform 3 in response to chronic metabolic and respiratory acidosis
(SPRINGERNEW YORK, 2012)
The Na+/H+ exchanger isoform 3 (NHE3) is essential for HCO3- reabsorption in renal proximal tubules. The expression and function of NHE3 must adapt to acid-base conditions. The goal of this study was to elucidate the ...
Perioperative cardiovascular evaluation: heads or tails?
(ASSOC MEDICA BRASILEIRASAO PAULO, 2012-07)
When dealing with surgical patients, a perioperative evaluation is essential to anticipate complications and institute measures to reduce the risks. Several algorithms and exams have been used to identify postoperative ...
Increased Glyceride-Glycerol Synthesis in Liver and Brown Adipose Tissue of Rat: In-Vivo Contribution of Glycolysis and Glyceroneogenesis
(SPRINGER HEIDELBERGHEIDELBERG, 2012)
We have previously shown that a high-protein, carbohydrate-free diet can decrease the production of glycerol-3-phosphate (G3P) from glucose and increase glyceroneogenesis in both brown (BAT) and epididymal (EAT) adipose ...
Vascular smooth muscle cells exhibit a progressive loss of rigidity with serial culture passaging
(IOS PRESSAMSTERDAM, 2012)
One drawback of in vitro cell culturing is the dedifferentiation process that cells experience. Smooth muscle cells (SMC) also change molecularly and morphologically with long term culture. The main objective of this study ...
Changes in spatial and temporal gene expression during incompatible interaction between common bean and anthracnose pathogen
(ELSEVIER GMBH, URBAN & FISCHER VERLAGJENA, 2012)
Common bean, one of the most important legumes for human consumption, may have drastic reduction in yield due to anthracnose, a disease caused by the fungus Colletotrichum lindemuthianum. Rapid induction of the plant defense ...
Suppression of Inflammatory Cytokine Secretion by an NF-kappa B Inhibitor DHMEQ in Nasal Polyps Fibroblasts
(KARGERBASEL, 2012)
Background: NF-kappa B is an essential transcription factor strongly associated to inflammatory response in chronic rhinosinusitis with nasal polyps (CRSwNP). DHMEQ is a NF-kappa B inhibitor that has been previously described ...
On the Denaturation Mechanisms of the Ligand Binding Domain of Thyroid Hormone Receptors
(AMER CHEMICAL SOC, 2010)
The ligand binding domain (LBD) of nuclear hormone receptors adopts a very compact, mostly alpha-helical structure that binds specific ligands with very high affinity. We use circular dichroism spectroscopy and high-temperature ...
Somatic embryogenesis of a wild passion fruit species Passiflora cincinnata Masters: histocytological and histochemical evidences
(SPRINGER WIENWIEN, 2012)
The characterization of cellular changes that occur during somatic embryogenesis is essential for understanding the factors involved in the transition of somatic cells into embryogenically competent cells and determination ...
Validation of reference genes for RT-qPCR normalization in common bean during biotic and abiotic stresses
(SPRINGERNEW YORK, 2012)
Selection of reference genes is an essential consideration to increase the precision and quality of relative expression analysis by the quantitative RT-PCR method. The stability of eight expressed sequence tags was evaluated ...
