McFadden, Bruce A. (Washington State University, Pullman), and H. Robert Homann. Quantitative studies of the effect of organic substrates and 2,4-dinitrophenol on heterotrophic carbon dioxide fixation in Hydrogenomonas facilis. J. Bacteriol. 86:971-977. 1963.-Whole cells of Hydrogenomonas facilis under heterotrophic conditions fixed levels of C(14)O(2) which depended upon the nature of the carb...

PURPOSE To date, there have been no studies identifying the cost differential for performing closed reduction internal fixation (CRIF) of hand fractures in the operating room (OR) versus an ambulatory setting. Our goal was to analyse the cost and efficiency of performing CRIF in these two settings and to investigate current practice trends in Canada. METHODS A detailed analysis of the costs i...

Chloroplasts isolated from Populus deltoides leaves were used to study age-dependent changes in the rate of cyclic photophosphorylation. Single leaves were used to measure CO(2) fixation by leaf discs, chlorophyll concentration, and ATP synthesis. The ability of chloroplasts to synthesize ATP diminished steadily from the time of full leaf expansion, regardless whether the results are expressed ...

introduction fracture - dislocations of the talus are typically due to high energy injuries. displaced fracture - dislocations of the talus have poor outcomes in general and complications are common. although talar fracture is common and comprises the second most common tarsal fracture, bilateral fracture - dislocations of the talus are rare. not many reports regarding the subject can be found ...

objective: the aim of this study was to assess skeletal relapse in patients who underwent mandibular setback by bilateral sagittal split ramus osteotomy (bssro) and osteosynthesis wiring techniques. materials and methods: in this semi-experimental study, 10 patients (8 women, 2 men) with 3-8 millimeters overjet underwent mandibular setback with bssro, osteosynthesis wiring and inter maxillary f...

Previous studies of photosynthetic carbon fixation in the marine alga Gonyaulax have shown that the reaction rates in vivo vary threefold between day and night but that the in vitro activity of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco), which catalyzes the rate-limiting step in this process, remains constant. Using protein gel blotting, we confirm that Rubisco protein levels are...

The mechanism for hologram formation by fixation-free rehalogenating bleaching has been treated by several authors. Experiments carried out with Kodak and Agfa photographic plates have led to the conclusion that the transfer of material from the exposed to the unexposed zones is the main mechanism that drives the process. We show that when BB-640 emulsion is used in the recording of holograms b...

background distal radius fracture is common in all ages. mobility and wrist function is important. the choice of treatment should aim for optimal function with minimal complications. objectives in this study we compared two surgical approaches, open reduction and internal fixation (orif) and closed reduction with external fixation (cr + ef), for treatment of intra-articular distal radius fractu...

Computational models of category learning and attention have historically focused on capturing trial and experiment level interactions between attention and decision. However, evidence has been accumulating that suggests that the moment-to-moment attentional dynamics of an individual affects both their immediate decision-making processes as well as their overall learning performance. To extend ...
