Microscopic observations on commercial sepharose: Deviations from normal bead-structure

Electron Microscopic Observations on T

Electron microscopic study of the H.R. strain of herpes simplex virus in cells of the chicken chorioallantoic membrane (1) suggested that the virus differentiates within the nucleus, where particles possessing a central core and a single limiting membrane are randomly dispersed. In this earlier work the finding that ruptured nuclei were associated with large numbers of intracytoplasmic particle...

Electron microscopic observations on avian esophageal epithelium.

The stratified squamous epithelium of the chicken and pigeon esophageal mucosa was studied mainly with the electron microscope. 1. The basal and spinous cells contained well-developed Golgi complexes, many mitochondria and multivesicular bodies. In the chicken basal cell a centriole and a single cilium were found. Both cells were rich in free ribosomes; the cisternae of the granular endoplasmic...

The microscopic structure of normal human synovial tissue.

An index for quantifying deviations from normal gait.

A method is derived to calculate the amount by which a subject's gait deviates from an average normal profile, and to represent this deviation as a single number. The method uses principal component analysis to derive a set of 16 independent variables from 16 selected gait variables. The sum of the square of these 16 independent variables is interpreted as the deviation of the subject's gait fr...

Observations on the Normal Diet

What is the normal diet ? How much solid food is required daily by a healthy adult, and what should be the relative proportions of the organic constituents ? The tables compiled by physiologists on these important points contain striking discrepancies which can be easily accounted for; some of the statistics being taken from barracks, workhouses, and other institutions where great economy has t...
