Estimated copper requirements of angus and simmental heifers.

In Exp. 1, Simmental (n = 21) and Angus (n = 21) heifers, approximately 9 mo of age, were used in a 160-d study to determine the effect of dietary Cu on growth and Cu status. Two- or three-yr-old first-calf heifers (21 Angus and 21 Simmental) entering into their last trimester of pregnancy were used in Exp.

Evaluation of crossbred calf and cow types for the coastal plain of North Carolina.

Data in this experiment consisted of 418 lactation records, and weaning and birth weight records from 600 crossbred calves. The traits evaluated included birth weight, weaning weight, weaning weight per cow exposed, weaning weight per weight of cow, weaning weight per weight of cow exposed, and predicted milk yield. Angus, Brangus, and Gelbvieh sires were mated to purebred Hereford cows.

Serum antibody responses of cattle to iron-regulated outer membrane proteins of Pasteurella haemolytica A1.

Serum antibody responses to the 70, 77, and 100 kDa iron-regulated outer membrane proteins (IROMPs) of Pasteurella haemolytica A1 were studied in cattle vaccinated with outer membrane protein (OMP) enriched outer membrane fraction, IROMP-enriched outer membrane fraction or live P. haemolytica. Vaccination with an IROMP-enriched outer membrane fraction stimulated antibodies to the 70 kDa IROMP, whereas vaccination with live P.

Psychosexual changes associated with the perimenopausal period.

The perimenopausal period is often a frustrating time for the woman who is experiencing it and for the health care professional who provides care for her. Although menopause is a universal experience for women, how it is experienced is not universal. Physiology, anatomy, social support systems, culture, expectations, and the woman's attitudes (especially her self-image) all have an influence on how easy or difficult the perimenopausal transition period is for an individual.

Personality factors in failure to adapt to the military.

As technical training costs increase in the military, it is increasingly important to identify and eliminate as soon as possible individuals unwilling or unable to adapt to the demands of the military. The present study compares three groups of enlisted personnel below the rank of E-4: a group having adjustment problems but motivated to remain in the military, a group having adjustment problems and seeking a discharge, and a well-adjusted group. Two scales of a personality inventory were found to differentiate the groups and suggest potential value for screening of military applicants.

Recent innovations in childbirth. Dangerous proposals, harmless fads, or wave of the future?

In recent years, consumers have become increasingly involved in their own health care and increasingly assertive vis à vis the medical profession. Nowhere has this been more apparent than in the area of childbirth. A number of individuals both within and outside of the medical profession have advocated changes in traditional childbirth practices.

Obsessive-compulsive disorder apparently related to abortion.

This case study presents a young woman who developed a severe obsessive-compulsive disorder after a routine medical procedure. It is suggested that this procedure brought back repressed guilt from three abortions and thus led to the onset of symptoms. The case is discussed in relationship to available research and theory.

Rorschach comparisons of male juvenile sex offenders and nonsex offenders.

Published research is limited on the psychological characteristics of juvenile sex offenders as a subgroup separate from other juvenile delinquents. This study compares 45 male adolescent sex offenders on the Rorschach with a matched group of nonsex adolescent offenders. The two groups differed in total number of responses.

Effect of test order on Rorschach human and movement responses.

Clinicians have traditionally tended to administer the Rorschach last in a test battery, despite some concern that projectives may be particularly susceptible to the influence of immediately preceding stimuli, including other tests. Research in this area has suffered from methodological problems and has produced equivocal results. In the present study the effect of administration of the Hand Test immediately before or immediately after the Rorschach was investigated.

Progeny tested sires compared with pedigree selected young sires.

First lactation records of 109,589 cows in 1,978 Holstein herds cooperating with three artificial insemination studs in young sire sampling were studied to compare performance of progeny of approximately the upper 15, 2, and 25% of sires, dams, and maternal grandsires for milk yield with selection differentials of +350, +2735, and +268 kg milk when the young sires entered sampling programs. The 315 young bulls were sired by 88 sires. Mean weighted Predicted Differences for sires proven through artificial insemination were 130 kg milk and 4.

Adenocarcinoma arising in a sigmoid diverticulum: report of a case.

A case of adenocarcinoma arising in a sigmoid diverticulum is presented. A patient who had colonic diverticulosis was found to have one diverticular lumen distended by tumor mass. Microscopically, this was seen to be adenocarcinoma arising from the diverticular mucosa.
