The benefits of the "no-touch" isolation technique usually performed to prevent the circulation of tumor cells are not evident. The aim of this study was to determine whether conventional surgical procedures for treatment of colon cancer could provoke the circulation of tumor cells detected by a genetic technology.Sixteen patients undergoing resection for colorectal cancer and two patients with irresectable tumors were studied. No patient showed liver or lung metastasis. With specific primers for ...

Arabinogalactan proteins (AGPs) are a highly diverse family of glycoproteins that are commonly found in most plant species. However, little is known about the physiological and molecular mechanisms of their function. AGPs are involved in different biological processes such as cell differentiation, cell expansion, tissue development and somatic embryogenesis. AGPs are also involved in abiotic stress response such as salinity modulating cell wall expansion. In this study, we describe how salt-adaptation ...

Cells of the monocyte/macrophage lineage express specific receptors for calcitriol (1,25-dihydroxyvitamin D3) and secrete prostaglandins and several cytokines with potent effects on bone metabolism. The aim of this study was to determine the effect of calcitriol on the secretion of prostaglandin E2 (PGE2), interleukin-1 (IL-1), and tumor necrosis factor (TNFα). Monocyte-enriched peripheral blood mononuclear cells (PBMC) from healthy subjects were cultured in the presence or absence of calcitriol (10−11 − ...

Abstract The metabolic syndrome (MetS) is a cluster of cardiovascular risk factors which has been suggested to have a possible effect on bone mass. Somewhat paradoxically, it is not clear whether this effect is protective or detrimental. Some of its components (e.g., obesity) seem to have the first type of effect and others (e.g., glucose metabolism changes) the second one. The epidemiological studies are not conclusive. Five out of six cross-sectional studies show no differences in the rate of fractures between ...

The alkylating agent N-ethoxycarbonyl-2-ethoxy-1,2-dihydroquinoline (EEDQ) is a peptide-coupling agent that is being used to inactivate irreversibly alpha 2-adrenoceptors and other receptors. The aim of the present study was to assess the in vitro and in vivo effects of EEDQ on the newly discovered brain I2-imidazoline sites, located mainly in mitochondria. Preincubation of rat cortical membranes with EEDQ (10(-8)-10(-5) M) markedly decreased (20-90%) the specific binding of the selective antagonist [ ...

During a study undertaken to characterize the time course of the osteocalcin response to bone fractures, lower than normal values of serum osteocalcin (1.7 +/- 0.9 vs. 3.3 +/- 1.3 ng/ml, P < 0.001) were found in the basal samples (blood obtained 48-72 h after fracturing). Suspecting that such a decrease could be due to the stress response induced by the fracture, for corticosteroids are known to diminish serum osteocalcin, we extended our study to another two stressful situations of high stress: acute myocardial ...

This work analyses the spatial distribution, the origin, and the shale-normalised fractionation patterns of the rare earth elements (REE) in the alluvial aquifer of the Guadiamar River (south-western Spain). This river received notoriety in April 1998 for a spill that spread a great amount of slurry (mainly pyrites) and acid waters in a narrow strip along the river course. Groundwaters and surface waters were sampled to analyse, among other elements, the REEs. Their spatial distribution shows a peak ...

Agmatine, the proposed endogenous ligand for imidazoline receptors, has been shown to attenuate tolerance to morphine‐induced antinociception ( Kolesnikov et al. , 1996 ). The main aim of this study was to assess if idazoxan, an α 2 ‐adrenoceptor antagonist that also interacts with imidazoline receptors, could also modulate opioid tolerance in rats and to establish which type of imidazoline receptors (or other receptors) are involved. Antinociceptive responses to opioid drugs were determined by the tail‐ ...

Chemical modification of biological materials used in the manufacture of cardiac valves tends to reduce the relatively high degree of biodegradation and calcification of the implanted bioprostheses. The most widely used treatment to reduce biodegradability of the valves is glutaraldehyde fixation. However, this treatment is potentially toxic and induces tissue calcification. In order to minimize these undesirable effects, we have analyzed the effect of a pre-fixation of endogenous proteoglycans ...

Two polymorphisms of the aromatase and estrogen receptor genes appeared to interact to influence the risk of hip fractures in women. Allelic variants of the aromatase gene have been associated with bone mineral density and vertebral fractures. Our objective was to analyze the relationship between two polymorphisms of the aromatase and estrogen receptor genes and hip fractures. We studied 498 women with hip fractures and 356 controls. A C/G polymorphism of the aromatase gene and a T/C polymorphism ...

Therapeutic application of intravenous administered (IV) human bone marrow-derived mesenchymal stem cells (ahMSCs) appears to have as main drawback the massive retention of cells in the lung parenchyma, questioning the suitability of this via of administration. Intraarticular administration (IAR) could be considered as an alternative route for therapy in degenerative and traumatic joint lesions. Our work is outlined as a comparative study of biodistribution of 99mTc-ahMSCs after IV and IAR administration, ...

Amalgamation was heavily used in mining since 1557 in Spanish Colonies. In Mexico and other parts of Latin-America,this process generated tailings which were left aside in the mine backyards. In the valley of Zacatecas, tailings were carried out of the mines due to the run-off from the mountains and contaminated most of the Zacatecan Valley which most important economic activity is agricultural (crop and livestock raising). The main concern in this area is the high level of total mercury found in ...
