Feces from 1,451 horses entering a veterinary hospital over a 13-month period were cultured for salmonella. A total of 46 horses (3.2%) yielded 1 or more salmonella-positive fecal cultures.

The valine requirement of the kitten was studied using a crossover design with two groups of three weanling kittens. The kittens were fed a semipurified diet containing only free amino acids as a source of nitrogen containing 0.0%, 0.

Cervical spinal cord injury without demonstrable bony injury occurred in 141 (37%) of 384 successive neck injuries admitted to the Sheffield Spinal Injuries Unit. The condition was common in patients in the older age-groups and there were 70% of the cases who were over the age of 50 years. The commonest cause was a fall.

A general procedure for calculating all the eigenmodes of optical resonators with mirrors having Gaussian reflectivity profiles is described. The eigenmodes are expanded in terms of the freely propagating Her-mite-Gaussian beams. The expansion enables one to apply well known matrix techniques to this kind of systems.

[High risk factors of breast cancer].

J Gynecol Obstet Biol Reprod (Paris)

December 1976

The authors analyse the various high-risk factors for breast cancer which have been described by many authors and their relative importance and intricacies. Some of these factors are concerned with the age of the patient, some with the time the periods started, some with the time the menopause occured and whether this was natural or artificial.

The survival periods in 331 cases of quadriplegia are reviewed. Important features are degree of injury, age at time of accident and ability to survive the first three months. A comparison of comparable circumstances is essential if we are to correctly interpret our respective mortality rates.

Tumor-specific antigen was extracted with 3 M KCl from line-10 guinea pig hepatoma cells. The yield of antigenic activity, estimated by production of delayed cutaneous hypersensitivity reactions in line-10 immune guinea pigs, was 10-30% of the antigen present in intact cells. By ultracentrifugation criteria, the extracted antigen was soluble.

Tumor-specific antigens of cells of the diethylnitrosamine-induced hepatomas in strain-2 guinea pigs were extracted with 3 M KCl. Immunization of normal animals with the extracted tumor antigens in adjuvant protected them against a subsequent challenge with viable tumor cells. Extracted tumor-specific antigens were less effective immunogens than viable tumor cells for both of two antigenically distinct lines.

An open resonator that consists of a spherical mirror and a reflection grating is described. The eigenmodes and eigenvalues are calculated numerically, utilizing the Fox and Li iterative method. By proper design of the grating, one may control the amount of energy coupled out through the grating's orders while the eigenmodes are almost unaffected.

Doses of heavy particles at positions inside the command modules of Apollo missions 8, 12, 14, and 16 correlate well with the calculated effects of solar modulation of the primary cosmic radiation. Differences in doses at different stowage positions indicate that the redistribution of mass within the spacecraft could enhance safety from the biological damage that would otherwise be expected on manned, deep-space missions.
