Effects of differential ventilation with general vs. selective right (R) and left (L) positive end-expiratory pressure (PEEP) on left (LV) and right ventricular (RV) end-diastolic dimensions were compared in seven pentobarbital-anesthetized dogs. All three modes of PEEP reduced LV cross-sectional...
Unfortunately, drugs that effectively manage negative and cognitive symptoms are still forthcoming. This is a particularly urgent issue as impaired cognitive function is a core symptom of schizophrenia (Andreasen, 2000; Freedman, 2003) and improvements in this domain are particularly strong predictors of...
Various forms of exercise have been shown to prevent, restore, or ameliorate a variety of brain disorders including dementias, Parkinson’s disease, chronic stress, thyroid disorders, and sleep deprivation, some of which are discussed here. In this review, the effects on brain function of various...
Selective PEEPPericardial pressurePleural pressureEffects of general (G) versus selective (S) right (R) and left (L) positive end-expiratory pressure (PEEP) were compared during differential lung ventilation in 11 anaesthetized dogs in the supine position. GPEEP 20 cmH2O decreased cardiac output (...
An individual requires one type of respiratory assist device (e.g., a negative pressure ventilator with a chest shell) for part of the day and needs a different type of respiratory assist device (e.g., positive pressure respiratory assist device with a nasal mask) during the rest of the ...
mutations and synonymous mutations, which do not alter the protein’s amino acid sequence. Classically,dN/dS > 1 is consistent with positive selection as nonsynonymous mutations occur more frequently than synonymous mutations,dN/dS < 1 is consistent with negative selection, anddN/dS ~...
Like negative body image, researchers have examined demographic differences in positive body image. Much of this work has focused on the body appreciation component, drawing on the widely used and well-validated Body Appreciation Scale (both the original and second versions of the measure; Avalos et...
Pseudomonas aeruginosa also grows well on a selective agar containing the disinfectant ‘cetrimide’ and in many solutions. Oxidase test: Pseudomonas species are, characteristically, strongly oxidase positive in contrast to ‘coliform’ species which are oxidase negative. Differential tests Pseudomonas aerugi...
In addition, we searched for positively selected codons under the assumption that proteins that are critically involved in virus replication, transmission and adaptation to the host immune system could be evolving, at least in part, under positive selective pressure34–36. Results Complete sequences ...
(2) In a group of diversified species of Scutellaria, does a selective pressure exist on DFR and what kind of evolutionary mechanism lead the duplicated paralogs to persist in the genome? To answer these questions, phylogenetic and population genetics analyses of hundreds of angiosperm DFR sequence...
