El presente estudio de investigación demuestra que es viable la recuperación oro y zinc en minerales marmatitico con contenido oro. Se analizó mediante diseños experimentales factoriales, utilizando los reactivos: CuSO4, AR-3418 AR-1242 como variables independientes; el resto las se mantuvieron constantes.
 Como resultado obtuvo un modelo para zinc, realizando análisis del diseño factorial...
Arachidonic acid (AA) released from membrane phospholipids by phospholipase A2 (PLA2) is important as a substrate for eicosanoid formation and as a second messenger for superoxide anion (O2-) generation in neutrophils. Different isoforms of PLA2 in neutrophils might mobilize AA for different functions. To test this possibility, we sought to characterize the PLA2s that are activated by the neutr...
When 93.3 to 933 (mu)mol of Aroclor 1242 per kg was added to Hudson River sediment test tube microcosms, the rates of polychlorinated biphenyl biotransformations increased with increasing Aroclor 1242 concentration after a 4- to 8-week acclimation period. In contrast, when 37.3 (mu)mol of Aroclor 1242 per kg was added, polychlorinated biphenyl biotransformations occurred at slow constant rates.
Polychlorinated biphenyls (PCBs) are known to be immunotoxic, yet the effects on neutrophil (PMN) function are not well characterized. We incubated PMNs isolated from rat peritoneum with a mixture of PCB congeners, Aroclor 1242, in the absence or presence of either phorbol myristate acetate (PMA) to stimulate generation of superoxide anion (O2-) or N-formyl-methionyl-leucyl-phenylalanine (fMLP)...
AIMS To audit the information content of pathology reports of colorectal cancer specimens in one National Health Service region. METHODS All reports of colorectal cancer resection specimens from the 17 NHS histopathology laboratories in Wales during 1993 were evaluated against: (a) standards previously agreed as desirable by pathologists in Wales; and (b) standards considered to be the minimu...
The Hsp90 facilitates proper folding of signaling proteins associated with cancer progression, gaining attention as a target for therapeutic intervention. The natural rotenoid deguelin was identified as an Hsp90 inhibitor, but concerns about neurotoxicity have limited prospects for clinical development. In this study, we report progress on deguelin analogues that address this limitation, focusi...
The satellite cells, which serve as adult muscle stem cells, are both located beneath myofiber basement membranes and closely associated with capillary endothelial cells. We observed that 90% of capillaries were associated with pericytes in adult mouse and human muscle. During post-natal growth, newly formed vessels with their neuroglial 2 proteoglycan (NG2)-positive pericytes became progressiv...
The rate and extent of degradation of Aroclor 1242 from contaminated surface soil was investigated, using aceticlastic mathanogenic consortia enriched from municipal anaerobic digester. Two different experiments, “intermediate feed” and “starve and feed” were conducted using triplicate 160-mL serum bottle microcosms, containing either 0.1 g, 1 g, 10 g, or 50 g of soil plus 100 mL of the inoculu...

Background: Interprofessional collaboration potentially enhances patient safety and satisfaction, and reduces tensions and conflicts among health professionals. However, health professionals often lack sufficient knowledge of other professional roles and competences to engage in interprofessional teamwork. The aim of this study was to assess the impact of an interprofessional training programme...
