Cell autonomy of the mouse claw paw mutation.
Mice homozygous for the autosomal recessive mutation claw paw (clp) are characterized by limb posture abnormalities and congenital hypomyelination, with delayed onset of myelination of the peripheral nervous system but not the central nervous system. Although this combination of limb and peripheral nerve abnormalities in clp/clp mice might suggest a common neurogenic origin of the syndrome, it ...
متن کاملThe effect of the mouse mutation claw paw on myelination and nodal frequency in sciatic nerves.
Despite the biophysical and clinical importance of differentiating nodal and internodal axolemma, very little is known about the process. We chose to study myelination and node of Ranvier formation in the hypomyelinating mouse mutant claw paw (clp). The phenotype of clp is delayed myelination in the peripheral nervous system. The specific defect is unknown but is thought to arise from a breakdo...
متن کاملNewtons levitation theorem and photoacoustic integral geometry
Two subjects are addressed. A series of mass distributions is explicitly presented, that generate zero gravitation eld in an open set in E. Second, an explicit reconstruction formula in E from data of spherical means with centers in an algebraic set. For both constructions, the same geometric method is applied based on properties of a special class of polynomials. Key words oscillatory set hyp...
متن کاملPosture Does Not Matter! Paw Usage and Grasping Paw Preference in a Small-Bodied Rooting Quadrupedal Mammal
BACKGROUND Recent results in birds, marsupials, rodents and nonhuman primates suggest that phylogeny and ecological factors such as body size, diet and postural habit of a species influence limb usage and the direction and strength of limb laterality. To examine to which extent these findings can be generalised to small-bodied rooting quadrupedal mammals, we studied trees shrews (Tupaia belange...
متن کاملNoisy Newtons: Unifying process and dependency accounts of causal attribution
There is a long tradition in both philosophy and psychology to separate process accounts from dependency accounts of causation. In this paper, we motivate a unifying account that explains people’s causal attributions in terms of counterfactuals defined over probabilistic generative models. In our experiments, participants see two billiard balls colliding and indicate to what extent ball A cause...
