Atomic coordinates are presented for yeast tRNA(Phe) derived from a wire skeletal model fitted to an electron density map at 2.5 A resolution obtained by isomorphous replacement.
Models for generating repetitive impulse activity were developed based on multicompartmental representations of ganglion cell morphology in the amphibian retina. Each model includes five nonlinear ion channels and one linear (leakage) channel. Compartmental distribution of ion channel type and density was designed to simulate whole cell recording experiments carried out in the intact retina-eye...
A new type of lightweight plaster with the thermal capacity enhanced by PCM (Phase Change Material) addition is analyzed. The basic physical characteristics, namely the bulk density, matrix density, total open porosity, and pore size distribution are measured at first. For description of mechanical properties, compressive strength measurements are done. The thermal properties are characterized ...
abstract background: regarding the variety of tests present for detecting and also screening prostate cancer and also bearing in mind the advantages and disadvantages of these tests we decided to re-evaluate these tests (total prostate specific antigen and all of its modifications) in detecting prostate cancer in men with intermediate serum psalevels. methods: following a cross sectional st...
