Is cell size a spandrel?
All organisms control the size of their cells. We focus here on the question of size regulation in bacteria, and suggest that the quantitative laws governing cell size and its dependence on growth rate may arise as byproducts of a regulatory mechanism which evolved to support multiple DNA replication forks. In particular, we show that the increase of bacterial cell size during Lenski's long-ter...
متن کاملTotal Knee Replacement Sizing: Shoe Size Is a Better Predictor for Implant Size than Body Height
Background: Various sizes of implants need to be available during surgery. The purpose of this paper is to comparebody height and shoe size with implant sizes in patients who underwent total knee replacement surgery to see whichbiomarker is a better predictor for preoperative planning to determine implant size.Methods: A total of 100 knees, belonging to 50 females and 50 males, were observed. P...

متن کاملPhenotypic spandrel: absolute discrimination and ligand antagonism.
We consider the general problem of sensitive and specific discrimination between biochemical species. An important instance is immune discrimination between self and not-self, where it is also observed experimentally that ligands just below the discrimination threshold negatively impact response, a phenomenon called antagonism. We characterize mathematically the generic properties of such discr...
متن کاملCell size control is sirtuin(ly) exciting
In the classic essay ‘On longevity and shortness of life’Aristotle speculated on the causes of the length or brevity of lifespan. More than 23 centuries ago, he postulated that three factors have major effects on longevity: metabolic rate, reproductive rate, and size. Remarkably, these observations still hold true. However, the molecular and genetic mechanisms that are responsible for these fun...
