Most data on mortality and prognostic factors in patients with heart failure come from North America Europe, little information other regions. Here, the International Congestive Heart Failure (INTER-CHF) study, we aimed to measure at 1 year Africa, China, India, Middle East, southeast Asia South America; also explored demographic, clinical, socioeconomic variables associated mortality.We enrolled consecutive (3695 [66%] clinic outpatients, 2105 [34%] hospital patients) 108 centres six...
Increased levels of endothelin-1 (ET-1) in the carotid body (CB) contribute to enhancement chemosensory responses acute hypoxia cats exposed chronic intermittent (CIH). However, it is not known if ET receptor types A (ETA-R) and B (ETB-R) are upregulated. Thus, we studied expression localization ETA-R ETB-R using Western blot immunohistochemistry (IHC) CBs from cyclic hypoxic episodes, repeated during 8 hr for 4 days. In addition, determined ET-1 expressed chemoreceptor cells double...
The angiogenic and invasive properties of the cytotrophoblast are crucial to provide an adequate area for feto-maternal exchange. present study aimed at identifying localization interrelated angiogenic, hyperpermeability vasodilator factors in interface pregnant guinea-pigs.Utero-placental units were collected from early term pregnancy. VEGF, Flt-1, KDR, B2R eNOS analyzed by immunohistochemistry, intensity signals placenta syncytial streamers was digitally analysed. Flt1 content placental...
Trivalent samarium (Sm3+) doped hafnium oxide (HfO2) films were deposited using the spray pyrolysis deposition technique. The on Corning glass substrates at temperatures ranging from 300 to 550 °C chlorides as raw materials. Films, mostly amorphous, obtained when below 350 °C. However, for higher than 400 °C, became polycrystalline, presenting HfO2 monoclinic phase. Scanning electron microscopy of revealed a rough surface morphology with spherical particles. Also, energy dispersive analysis...
Abstract Background In humans trophoblast invasion and vascular remodeling are critical to determine the fate of pregnancy. Since guinea-pigs share with women an extensive migration trophoblasts through decidua uterine arteries, a haemomonochorial placenta, this species was used evaluate spatio-temporal expression three enzymes that have been associated invasion, MMP-2, MMP-9 tissue kallikrein (K1). Methods Uteroplacental units were collected from early term K1 analysed by...
Background. Whether calcitriol administration, which is used to treat secondary hyperparathyroidism in dialysis patients, induces regression of parathyroid‐gland hyperplasia remains a subject interest and debate. If the parathyroid gland were occur, presumed mechanism would be apoptosis. However, information on whether high doses can induce apoptosis cells hyperplastic glands lacking. Consequently, given azotaemic rats evaluated for Methods. Rats either sham‐operated (two groups) or...
Background. Kidney hypertrophy is stimulated by both partial nephrectomy and NH4Cl administration. Also, parathyroidectomy (PTX) has been reported to prevent kidney induced a high protein diet. Our goal was determine in the azotaemic rat: (i) combined effects of administration dietary phosphorus on development calcium deposition (ii) whether absence parathyroid hormone (PTH) affected deposition.
Vascular calcification has been widely recognized as a significant contributor to cardiovascular risk in patients with chronic kidney disease. Recent evidence suggests that BMP-7 decreases the vascular observed uraemic rats, while BMP-2 could also be participating this process. Gremlin, bone morphogenetic protein antagonist, detected rat aortic smooth muscle cells (VSMCs), and since role of VSMCs into uraemia is considered critical process, we hypothesized gremlin its pathogenesis. With aim,...
The crystal structure of heterocyclic compound 5-methyl-5-phenyl hydantoin has been determined from X-ray single structural characterization. This material crystallizes in the orthorhombic system and noncentrosymmetric space group P21 (N°4). packing is governed by N–H···O hydrogen bond-type intermolecular interactions, forming chains edge-fused 12-membered rings with graph-set C(4) C(5) C22(8) R33(12) a similar hydrogen-bonding pattern another chiral 5,5′-substituted hydantoins.
The presence of an alkali such as sodium hydroxide (NaOH) within a process enhanced recovery crude oil having certain acidity allows the formation surfactants with ability enhancing separation from reservoir rock where it is adsorbed due to change wettability. This work focused on studying effect NaOH recovery, in terms SARA composition, two different API gravity oils (38.5 and 24.1°) total acid number. results showed existence components high low reactivity oil, first group responsible...
Tissue kallikreins are present in rat uterus during the estrous cycle luminal and glandular epithelium, early gestation implantation node, last third of pregnancy surrounding sinusoids decidua basalis. The pattern kinin B2 receptor expression, through which vasoactive effect is exerted, was studied by vitro autoradiography immunohistochemistry. observed myometrium, endothelial cells arteries, veins venules, smooth muscle endometrial myometrial arterioles. Immunoblotting crude membranes...
Background. Both dietary phosphorus restriction and the ingestion of ammonium chloride (NH4Cl) given to rats on a high-phosphorus diet have been shown preserve renal function in azotaemic rat. Parathyroidectomy also has reported and, addition, prevent kidney hypertrophy remnant model. Our goals were (i) evaluate effect shorter time frame than previously studied (ii) determine whether NH4Cl administration (a) enhances renoprotective (b) improves absence parathyroid hormone (PTH). Methods....
