Fifty-five patients received total cardiopulmonary support with the disposable Lande-Edwards membrane oxygenator during aortocoronary artery-vein graft operations and other complex open heart operations. Two three meter2 membrane oxygenators were linked in parallel to a standard r o b pump apparatus. (Three 3 meter2 membranes for patients weighing 80 to 103 kg.) Excellent oxygen and carbon diox...

BIOPHYSICS AND COMPUTATIONAL BIOLOGY Correction for “Surface residues dynamically organize water bridges to enhance electron transfer between proteins,” by Aurélien de la Lande, Nathan S. Babcock, Jan Rezá c, Barry C. Sanders, and Dennis R. Salahub, which appeared in issue 26, June 29, 2010, of Proc Natl Acad Sci USA (107:11799–11804; first published June 14, 2010; 10.1073/pnas.0914457107). The...

To further investigate the (19)F and (1)H nuclear hyperfine structure and Zeeman effect in the simplest singlet carbene, HCF, we recorded polarization quantum beat spectra (QBS) of the pure bending levels 2(0) (n) with n = 0-7 and combination bands 1(0) (1)2(0) (n) with n = 1-6 and 2(0) (n)3(0) (1) with n = 0-3 in the HCF A(1)A(")<--X(1)A(') system. The spectra were measured under jet-cooled co...

To assess extinction risks of loggerhead DPSs, we conducted two independent analyses. The first analysis used the diffusion approximation approach based on time series of counts of nesting females or nests (Lande and Orzack 1988, Dennis et al. 1991, Holmes 2001, Snover and Heppell 2009). This analysis provided a metric (susceptibility to quasi-extinction or SQE) to determine if the probability ...

En 2009 était lancée l’étude préalable à la fermeture de décharge Penn ar Roc’h située en contexte pelouse et lande hauts falaises littorales. Des échanges entre le bureau d’étude charge environnementale des universitaires l’Université Bretagne occidentale menant travaux recherche sur restauration écologique permettent lancer une réflexion pour expérimentation d’ingénierie (transferts litière f...

-Although extensive work has been done on the relationship between population size and the risk of extinction due to demographic and environmental stochasticity, the role of genetic deterioration in the extinction process is poorly understood. We develop a general theoretical approach for evaluating the risk of small populations to extinction via the accumulation of mildly deleterious mutations...

Because of photoacclimation, frequency distributions of phytoplankton single-cell fluorescence reflect variation in light histories among individual cells. As a result, phytoplankton can be used as biological tracers for vertical mixing. A time series of Prochlorococcus single-cell fluorescence distributions in the Sargasso Sea revealed changes that were qualitatively consistent with changes in...

—Robust phylogenetic information can be instrumental to the study of the evolution of female mating preferences and preferred male traits. In this paper, the evolution of a preexisting female bias favoring a sword in male swordtail fish and the evolution of the sword, a complex character, are used to demonstrate how the evolution of mating preferences and preferred traits can be examined in a p...
