Bicuspid Valve Sizing for Transcatheter Aortic Valve Implantation: The Missing Link

open access: yesFrontiers in Cardiovascular Medicine, 2022
Transcatheter aortic valve implantation (TAVI) is a well-recognized and established therapy for severe aortic stenosis, with expanding indications toward younger patients with low surgical risk profile. As bicuspid aortic valve (BAV) affects ~1–2% of the

Brain size, body size and longevity [PDF]

open access: yesInternational Journal of Obesity, 2010
In this analysis, we bring together two research fields that have never been associated before: the clinical issue 'Quételet's body-mass index and longevity' and the comparative biological issue 'body-brain allometry'. Comparison of medical and biological data supports the view that body mass index is just a one-to-one mapping of the body-brain-energy ...

SIZE AND LOGIC

open access: yesThe Review of Symbolic Logic, 2009
We show how to develop a multitude of rules of nonmonotonic logic from very simple and natural notions of size, using them as building blocks.

Intron Size and Genome Size in Plants [PDF]

open access: yesMolecular Biology and Evolution, 2002
It has long been known that genomes vary over a remarkable range of sizes in both plants (Bennett, Cox, and Leitch 1997) and animals (Gregory 2001). It also has become evident that across the broad phylogenetic sweep, genome size may be correlated with intron size (Deutsch and Long 1999; Vinogradov 1999; McLysaght et al.

On the role of body size, brain size, and eye size in visual acuity [PDF]

open access: yesBehavioral Ecology and Sociobiology, 2017
The visual system is highly variable across species, and such variability is a key factor influencing animal behavior. Variation in the visual system, for instance, can influence the outcome of learning tasks when visual stimuli are used. We illustrate this issue in guppies (Poecilia reticulata) artificially selected for large and small relative brain ...
