Models of medusan swimming typically rely on kinematic approximations to observed animal morphology to make such investigations tractable. The effect of these simplifications on the accuracy of predicted dynamics has not been examined in detail. We conduct a case study of the scyphozoan jellyfish Chrysaora fuscescens to isolate and quantify the sensitivity of dynamic models to common kinematic ...
Genomes of animals as different as sponges and humans show conservation of global architecture. Here we show that multiple genomic features including transposon diversity, developmental gene repertoire, physical gene order, and intron-exon organization are shattered in the tunicate Oikopleura, belonging to the sister group of vertebrates and retaining chordate morphology. Ancestral architecture...
Animals make up only a small fraction of the eukaryotic tree of life, yet, from our vantage point as members of the animal kingdom, the evolution of the bewildering diversity of animal forms is endlessly fascinating. In the century following the publication of Darwin's Origin of Species, hypotheses regarding the evolution of the major branches of the animal kingdom - their relationships to each...
In this article, the impact of dietary lipids and heterotopic heart transplant procedures on the structure and morphology of several tissues in apolipoprotein E-knock out (apo E-KO) mice is reported. In particular, addition of dietary cholesterol, plant sterol or either changes in hemodynamic factors or immunological responses after heart transplant procedures are associated with histological a...
Human and animal movement is absolutely fascinating and can hardly be mimicked by technical devices, so far. It has been proposed that part of the movement generation and control can be associated to the non-linear characteristics of the bio-mechanical structures and morphology. Terms like morphological computation (Paul, 2006) and intelligence by mechanics (Blickhan et al., 2007) capture this ...
Microglia have a variety of functions in the brain, including synaptic pruning, CNS repair and mediating the immune response against peripheral infection. Microglia rapidly become activated in response to CNS damage. Depending on the nature of the stimulus, microglia can take a number of activation states, which correspond to altered microglia morphology, gene expression and function. It has be...
OBJECTIVE To design an experimental pediatric animal model of acute kidney injury induced by cisplatin. METHODS Prospective comparative observational animal study in two different phases. Acute kidney injury was induced using three different doses of cisplatin (2, 3 and 5 mg/kg). The development of nephrotoxicity was assessed 2 to 4 days after cisplatin administration by estimating biochemica...
