Con guration problems are a thriving application area for declarative knowledge representation that experiences a constant increase in size and complexity of knowledge bases. However, today's con gurators are designed for solving local con guration problems not providing any distributed con guration problem solving functionality. Consequently the challenges for the construction of con guration ...

In an attempt to modulate the recognition processes that occur on lymphocyte membranes in mixed lymphocyte culture, responding cortisone resistant thymocytes or stimulating spleen cells (treated with mitomycin C) were pretreated with native concanavalin A (N-Con A) or succinyl-Con A (S-Con A). Highly significant cell proliferation was observed in syngeneic combinations when either the respondin...

C menor a uno, y a la espera del tratamiento con leptina recombinante humana, solicitado como uso compasivo. Recibe trasplante doble renopancreático el 07/09/2015, con derivación intestinal. Recibió también inducción con ATG fresenius (15 mg/kg repartido en 5 dosis), profilaxis antibacteriana por 5 días con pipertazobactan, antimicótica por un mes, anti-CMV(por 3 meses) y anti-PCP por 2 años. S...

To determine the role of endothelin-1 (ET-1) and its receptors in the regulation of calcitonin gene-related peptide (CGRP) release, male Wistar rats were divided into six groups and subjected to the following treatments for 1 wk with or without ABT-627 (an ET(A) receptor antagonist, 5 mg.kg(-1).day(-1) in drinking water) or A-192621 (an ET(B)-receptor antagonist, 30 mg.kg(-1).day(-1) by oral ga...

The binding reaction between carcinoembryonic antigen (CEA) and concanavalin A (Con A) has been studied. CEA, prepared from liver métastasesin patients with carcinoma of the colon, was tested against Con A for precipitation. By using the techniques of immunodiffusion and counlerelectrophoresis, a precipitate line between CEA and Con A was observed, which was different from that seen between ei...

Two studies evaluated sorting and feeding zilpaterol hydrochloride (ZH) on feedlot performance and carcass characteristics in randomized block-designed finishing trials. In Exp. 1 (initial BW 342 ± 10 kg, = 1,000), 5 treatments included an unsorted non-ZH fed negative control (-CON), an unsorted ZH fed positive control (+CON), and 3 treatments in which the heaviest 20% within the pen were sorte...

Ischemic preconditioning (Pre-con) is an adaptive response triggered by a brief ischemia applied before a prolonged coronary occlusion. We tested the hypothesis that repetitive ischemia applied during early reperfusion, i.e., postconditioning (Post-con), is cardio-protective by attenuating reperfusion injury. In anesthetized open-chest dogs, the left anterior descending artery (LAD) was occlude...

El carcinoma colorrectal con células en anillo de sello es un subtipo infrecuente del adenocarcinoma mucinoso, constituyendo menos del 1% del total de tumores colorrectales1. Para el diagnóstico, debe existir un origen primario en colon o recto y al menos un 50% con patrón de células en anillo de sello. Habitualmente la presentación clínica es tardía, asociando una alta agresividad2. Describimo...

Experiments were designed to study development of bovine embryos in TCM-199 medium conditioned by preculture with buffalo rat liver (BRL) cells. Conditioned media were harvested after BRL cells were cultured until confluency (CON), or for an additional 2 d with the same cells but new medium (CON-N) or the same medium (CON-S). Glucose in TCM-199 was depleted by BRL cells to different concentrati...
