The results of 397 consecutive orthotopic hepatic transplantations in 333 recipients were reviewed. One or more surgical complications developed in 172 of 323 patients (55 per cent), excluding ten intraoperative deaths. The six month mortality rate among the patients with surgical complications (55 of 172; 32 per cent) was statistically higher than that among patients without such complications...

Background: Recurrent pregnancy loss (RPL), defined as 3 or more consecutive pregnancy failures, is a common and distressing disorder. Chromosome instability in the conceptus is the most common cause whereas uterine factors are invariably invoked to explain nonchromosomal miscarriages. These uterine factors are, however, poorly defined. Materials amd Methods: Laboratory-based analysis of endome...

Perceived trustworthiness is a critical antecedent of interpersonal trust, yet researchers have a limited understanding of how such perceptions are generated. The authors used 2 competing perspectives within the relational demography literature— similarity–attraction and relational norms—to empirically examine the effect of demographic differences. Whereas the similarity–attraction account sugg...

We investigated the bulk electrical conductivity and microbial population distribution in sediments at a site contaminated with light nonaqueous-phase liquid (LNAPL). The bulk conductivity was measured using in-situ vertical resistivity probes; the most probable num­ ber method was used to characterize the spatial distri­ bution of aerobic heterotrophic and oil-degrading mi­ crobial populations...

We have analyzed the topological organization of chromatin inside mitotic chromosomes. We show that mitotic chromatin is heavily self-entangled through experiments in which topoisomerase (topo) II is observed to reduce mitotic chromosome elastic stiffness. Single chromosomes were relaxed by 35% by exogenously added topo II in a manner that depends on hydrolysable adenosine triphosphate (ATP), w...

Studies were made of the influence of ICRF-187 on the functional and morphological effects of very large cumulative doses of doxorubicin given over a prolonged period of time. Adult beagles of either sex (6.2-11.6 kg) were given doxorubicin (1.75 mg/kg i.v.) either alone or 15 min after ICRF-187 (25 mg/kg, i.v.) at 3-week intervals. Control dogs received ICRF-187 (25 mg/kg, i.v.) or 0.9% saline...
