To define the prevalence of total coronary occlusion in hours after transmural myocardial infarction, we used arteriography to study degree obstruction 322 patients admitted within 24 infarction. Total was observed 110 126 (87 per cent) who were evaluated four onset symptoms; this proportion decreased significantly, 37 57 (65 cent), when studied 12 symptoms. Among 59 with angiographic features thrombosis, thrombus retrieved by Fogarty catheter 52 (88 but absent seven (12 cent false...
Understanding how and why biodiversity is structured across the globe has been central to ecology, evolution, biogeography even before those disciplines took their modern forms. Three global-scale patterns in particular have focus of research debate for decades: latitudinal gradients species richness (richness decreases with increasing latitude), body size (body increases latitude endotherms; Bergmann's rule), geographic range (range latitude; Rapoport's rule). Despite decades study,...
Abstract Experimental studies have demonstrated that nutritional changes during development can result in phenotypic to mammalian cheek teeth. This developmental plasticity of tooth morphology is an example plasticity. Because occurs through complex interactions between manifold processes, there are many potential mechanisms which contribute a tooth’s norm reaction. Determining the identity those and relative importance each them one main challenges understanding Quantitative proteomics...
Increasing variability down serially segmented structures, such as mammalian molar teeth and vertebrate limb segments, is a much-replicated pattern. The same phenotypic pattern has conflicting interpretations at different evolutionary scales. Macroevolutionary patterns are thought to reflect greater potential in later-forming but microevolutionary less plasticity. We address this conflict by recalculating (evolvability) from published data directly measuring plasticity controlled feeding...
As the discovery of cryptic species has increased in frequency, there been an interest whether geometric morphometric data can detect fine-scale patterns variation that be used to morphologically diagnose such species. We a combination and ensemble five supervised machine learning methods (MLMs) investigate plastron shape differentiate two putative turtle species, Actinemys marmorata pallida. focus considerable research due its biogeographic distribution conservation status. Despite this...
Abnormal responses to a standardized Valsalva maneuver have been proposed as additional criteria for heart failure. The present study was undertaken determine the variability of these in normal subjects well frequency abnormal cardiac patients. Only phase II could be considered reliable this purpose. Discrepancies between were observed relation other criteria.
Mammal tooth morphology and function correlate strongly with dietary ecology, convergence is a major feature of mammalian evolution. Yet, ecology are insufficient to explain morphological diversification within molar evolution; suggesting that development phylogeny also limit possible structural solutions selective pressures. Here, I use in silico models empirical studies extant fossil rodent teeth identify morphogenetic rules influence morphology. Because rodents the most diverse group...
We provide the first documentation of morphological variation in lower molar (m1) Lemmiscus curtatus from southern Canada. A total 370 specimens were obtained owl pellets taken 4 localities Saskatchewan. The most common morphotypes are, order descending relative abundance, molars with 5 closed triangles and a well-developed but widely open sixth triangle, triangle that is pinched at confluence anterior cap, incipient closure 6 triangles. As true other modern populations L. curtatus, samples...
