BACKGROUND The last case of polio associated with wild poliovirus (WPV) indigenous to the Democratic Republic of the Congo (DRC) was reported in 2001, marking a major milestone toward polio eradication in Africa. However, during 2006-2011, outbreaks associated with WPV type 1 (WPV1) were widespread in the DRC, with >250 reported cases. METHODS WPV1 isolates obtained from patients with acute f...

BACKGROUND Only a fraction of cigarette smokers develop lung cancer, suggesting that people differ in their susceptibility to this disease. We investigated whether differences in DNA repair capacity (DRC) for repairing tobacco carcinogen-induced DNA damage are associated with differential susceptibility to lung cancer. METHODS From August 1, 1995, through April 30, 1999, we conducted a hospit...

Two experiments were conducted to evaluate the effects of feeding wet corn gluten feed (WCGF) on subacute acidosis in cattle. In Exp. 1, 60 individually fed yearling steers (270 +/- 22 kg BW) were used in a 5 x 2 factorial arrangement of treatments. Steers were assigned to one of five dietary treatments: 1) dry-rolled corn (DRC), 2) 35% WCGF fed d 1 to 132, 3) 86.5% WCGF fed d 1 reduced to 35% ...

Understanding the spatial clustering of Plasmodium falciparum populations can assist efforts to contain drug-resistant parasites and maintain the efficacy of future drugs. We sequenced single nucleotide polymorphisms (SNPs) in the dihydropteroate synthase gene (dhps) associated with sulfadoxine resistance and 5 microsatellite loci flanking dhps in order to investigate the genetic backgrounds, g...

I f a picture paints a thousand words, the text generated by cryoelectron tomography (cryo-ET) could fi ll volumes. High resolution 3D reconstructions of fl agellar axonemes generated using cryo-ET are shaping our understanding of how structure relates to function, a point exemplifi ed by a new study which assigns a molecular identity to a formerly elusive ciliary structural feature—the nexin l...

This paper presents a semi-formal denotational definition of the semantics of a version of domain relational calculus called DRC. A single basic design principle governs the semantic definition: each predicate (or formula) of DRC denotes a relation. The definition obtained is precise, short, and systematic. Generalizations of operations of the relational algebra are suggested, which correspond ...

2.2 Na DRC estágios III e IV, a ingestão dietética de P deverá ser mantida em valores que atendam a recomendação de proteínas entre 0,6 e 0,8 g/kg/dia, porém não superior a 700 mg/dia se o P estiver acima dos valores normais e/ou se o paratormônio (PTH) estiver acima do nível recomendado para o estágio da DRC (Opinião). 2.3 Na DRC estágio V D, a ingestão dietética de P deverá estar entre 800 e ...

The neutron direct radiative capture (DRC) process is investigated, highlighting the role of incident p-wave neutrons. A set of calculations is shown for the C(n; ) process at incoming neutron energies up to 500 keV, a crucial region for astrophysics. The cross section for neutron capture leading to loosely bound s, p and d orbits of C is well reproduced by the DRC model demonstrating the feasi...
