Male mice treated with MPTP or vehicle were tested for their ability to demonstrate a memory-recognition response as evaluated in a habituation-dishabituation task. Treatment with MPTP severely disrupted the male's habituation-dishabituation response…
Identification of a 3100-year-old lithopedion in the Archaic Southwest antedates its first clinical notation by 21 00 years. It was only the ''autopsy'' of time (excavation of the site) that allowed its presence to be brought to light.
The following article presents a comprehensive overview of the practical aspects of radiation protection for diagnostic radiology. The topics discussed include background radiation levels, typical exposure levels for radiologic technologists, risk…
A technique is described for measuring electrophysiological multiple-unit activity and extracellular dopamine concentration with in vivo voltammetry at an array of 8 electrodes. In addition, new procedures in the construction of the voltammetric…
This study was designed to determine the influence of the hypothalamus on the content of vasoactive intestinal peptide (VIP) in the anterior pituitary. Disruption of the hypothalamic-pituitary connection was performed by ablating the arcuate-median…
BACKGROUND: Conventional wisdom holds that the elderly living in rural areas suffer poor health and have limited access to health care compared with their urban peers. The relation between poor health and limited access, however, has yet to be…
The influence of the release of endothelium-derived nitric oxide (NO) on the vasoconstrictor response to phenylephrine (PE) was evaluated before and after a single bout of dynamic exercise. Each rat ran on a motor-driven treadmill at
A 30-year-old, white woman, gravida 4, para 2, abortus 1, was hospitalized at 21 weeks' gestation because of a symptomatic pericardial effusion. Extensive evaluation including pericardial biopsy failed to reveal a specific cause. Treatment with…
This study was designed to ascertain whether individuals with mood disorders are particularly vulnerable to adverse effects of aspartame. Although the protocol required the recruitment of 40 patients with unipolar depression and a similar number of…
This is a review of 203 episodes of alpha-hemolytic streptococcal bacteremia during a 12-year period (1980-91) in a large community teaching hospital in the USA. There were 87 male and 116 female patients, with ages ranging from newborn infants to a…
The structure-function relationships of the 43-amino-acid membrane-binding domain of cytochrome b(5) have been examined in two mutant forms of the protein. In one mutant, two tryptophans in the membrane-binding domain, at positions 108 and 112, were…
The records of 167 patients who underwent both cone biopsy and hysterectomy at the University of Michigan Medical Center between 1974 and 1989 were reviewed. The presence or absence of neoplasia at the cone biopsy margins was able to be correlated…
Most practitioners working in community support settings understand the need to provide a comprehensive array of well-coordinated services to individuals with severe mental disabilities. However, a lack of consensus about the conceptual basis of…
BACKGROUND: A causal relationship between antigenic conditions and multiple myeloma was suggested by case reports. Although controlled studies identified associations with individual conditions, they failed to give overall support to the hypothesis.…

All the intact female Syrian hamsters treated with medroxyprogesterone (MP) for a one-month period, without dietary manipulation, display gallbladder surface epithelial changes, and intraluminal deposits. These changes include excrescences in various…
Analyses of New World skeletal populations for the presence of erosions an other osseous alterations and their character, distribution, and radiologic appearance shows that osteoarthritis is predominantly a disease of animals raised in artificially…
Sixty skeletons of Callithrix jacchus were examined to identify spondy-loarthropathy. Erosive disease in Callithrix was confirmed as spondy-loarthropathy on the basis of diagnostic sacroiliac erosions, syndesmophyte formation, and the nature and…
As the incidence of human immunodeficiency virus (HIV) infection increases, health care practitioners are being called upon to counsel and educate patients regarding the complications associated with HIV infection. In addition, the anxiety levels of…
Naloxone eliminates postexertional hypotension (PEH) in human and animal models. The effect of naloxone on sympathetic activity during hemorrhage and generation of arterial baroreflex function curves can be stimulated by blockade of cardiac afferent…
OBJECTIVES: To survey the attitudes of healthcare personnel regarding influenza immunization. DESIGN: A questionnaire was given to all hospital employees. SETTING: A 650-bed community teaching hospital. INTERVENTION: Employees were offered an…
We describe four families with a strong familial expression of Barrett's/gastroesophageal reflux disease (GERD) complex spanning one to four generations with two to seven affected members per family. The purpose of this report is to highlight genetic…
OBJECTIVE. Conversion of bone marrow in the extremities from red to yellow is a normal maturation process. Marrow reconversion is present when expected yellow marrow is replaced with active red marrow, and it tends to occur at times of physiologic…
Background: Numerous studies have reported differences in cancer staging at diagnosis and in survival between Black and White patients with breast cancer. Utilizing data obtained from the National Cancer Institute's (NCI's) Black/White Cancer…
Brittle diabetes is a therapeutic challenge. The first experience with a pocket Insulin Dosage Computer (IDC(TM)) in brittle diabetes was conducted in the form of a clinical N-of-1 trial. After intensified conventional therapy (ICT) the patients used…
Lateral ventricular administration of angiotensin II (ANG II) produces potent dipsogenic effects in water-sated rats. ANG II seems to require functional voltage-gated calcium channels on neurons throughout circumventricular brain sites to exert its…
The influence of cardiac afferents on the muscle metaboreflex was examined in 16 rats instrumented with a Silastic-tipped catheter in the pericardial space and right atrium, Doppler ultrasonic flow probe and a pneumatic vascular occluder around the…
Documentation of the antiquity and tracking of the derivation of human treponemal diseases have been complicated by an inability to distinguish among these diseases biochemically, histologically, and immunologically. Skeletal impact, as a population…
Cholesterol 7alpha-hydroxylase, the rate-determining enzyme in the bile acid biosynthesis pathway, is regulated in a negative feedback manner by hydrophobic bile salts returning to the liver via the portal circulation. The role of cholesterol in the…
Rats of the Sprague-Dawley strain were infused intravenously with a fat emulsion (Intralipid, trademark of Kabi Pharmacia, Uppsala, Sweden) containing 7-oxocholesterol. This resulted in an increased cholesterol 7alpha-hydroxylase activity in liver…
