In the accompanying paper 1 we have described the structure of paramyosin in molluscan muscles. A second type of fibrous muscle component is possibly of greater significance, since it has been found in all muscles thus far examined, in smooth and striated varieties from vertebrate and invertebrate animals (Schmitt, Bear, Hall, and Jakus, 1947). When first discovered by means of x-ray diffractio...

OBJECTIVE The goal of this study was to assess effects of translation (horizontal displacement) and angulation (transducer tilting) on 3-dimensional (3D) echocardiographic volumes of both balloons and human left ventricles after autopsy. METHODS Six water-filled (non-) aneurysmatic balloons of 150, 250, and 350 mL and 3 hearts of different sizes and shapes were suspended upright in a water ba...

1. Extractable hexokinase activity was measured in the red and white skeletal muscles of the rabbit and in the hearts and diaphragms of four animal species differing markedly in size. Activities vary over a 40-fold range, being least in white skeletal muscle of the laboratory rabbit and greatest in mouse heart. 2. Hexokinase activities correlate approximately with capacities to undertake reacti...

Calcineurin, a calcium/calmodulin-regulated protein phosphatase, modulates gene expression in cardiac and skeletal muscles during development and in remodeling responses such as cardiac hypertrophy that are evoked by environmental stresses or disease. Recently, we identified two genes encoding proteins (MCIP1 and MCIP2) that are enriched in striated muscles and that interact with calcineurin to...

Sometimes humans have a need for storing long sequences of information in memory. Several experiments show that grouping the items in the sequence helps storing the sequence in auditory short-term memory. One architecture used by connectionist cognitive researchers when representing and processing sequences is Recursive Auto-Associative Memory. One of the aspects of it is that its capacity for ...

This paper extends Imbens and Manski’s (2004) analysis of confidence intervals for interval identified parameters. For their final result, Imbens and Manski implicitly assume superefficient estimation of a nuisance parameter. This appears to have gone unnoticed before, and it limits the result’s applicability. I re-analyze the problem both with assumptions that merely weaken the superefficiency...
