In the present study we examined the ultrastructural modifications as well as the precise distribution of DNA and RNA in RT4 cell nucleoli following a 3-h exposure to nontoxic or toxic doses of ametantrone (AMT), poly(adenylate-uridylate)…
We discuss a model for the origin of cetacean swimming that is based on hydrodynamic and kinematic data of modern mammalian swimmers. The model suggests that modern otters (Mustelidae: Lutrinae) display several of the locomotor modes that early…
Select semipermeable amphiphilic membranes have been prepared and their diffusional characteristics for glucose, insulin, and albumin investigated. The membranes were prepared by cast copolymerization of a hydrophilic monomer (i.e., N,N-dimethyl…
Northeastern Ohio Universities College of Medicine's (NEOUCOM) response to an LCME mandate (1990) was to develop and administer a Comprehensive Clinical Competency Assessment (CCCA) to rising senior medical students. This paper presents facets of…
The four segments in the Life-span, life-space approach to comprehending and intervening in careers (individual differences, development, self, and context), constitute four perspectives on adaptation to life roles. Adaptation serves as a bridging…
The opportunity to examine the defleshed skeleton of an individual diagnosed in life (Hamann-Todd collection, individual 2036) afforded a unique opportunity to demonstrate the bone damage characteristic of at least one form of juvenile rheumatoid…
The paucity of convincing evidence for congenital bone lesions of syphilis in the archaeological record led to study of the human remains from the Buffalo site in West Virginia, dated at 550-650 years BP. The diagnosis of syphilis (venereal) in…
Though ubiquitous in community mental health agencies, case management suffers from a lack of consensus regarding its definition, essential components, and appropriate application. Meaningful comparisons of various case management models await such a…
Objective: Qualitative and quantitative evaluation of leukocyte activation in septic patients in comparison to two control groups. Design: A prospective clinical study in which the leukocyte oxidative output of whole blood was measured in three…
A 68-year-old man with coronary artery disease was admitted for chest pain and ventricular tachycardia, After electric cardioversion, therapeutic heparinization was started for myocardial ischemia and nontransmural infarction, On day 3, headache and…
The cytogenetic findings in pleuropulmonary blastoma (PPB) have not been widely studied and reported and are of interest in view of the implications that PPB has for additional tumors in the patient and the patient's relatives. Using standard tumor…
The Adult Career Concerns Inventory (ACCI) uses an attitudinal item-response scale to measure the planning attitudes dimension of career adaptability. This study examined the psychometric properties of the ACCI when used with a behavioral…
Superficial fungal infections are easily managed once the proper diagnosis is made. However, misdiagnosis is not uncommon, and many standard approaches to treatment popular just a few years ago are now out of date or in need of refinement. Through…
Angiotensin-converting enzyme (ACE) inhibitors and NSAIDs are among the drugs most commonly associated with acute renal failure (ARF). Patients at risk for ACE inhibitor-induced ARF include those with congestive heart failure (CHF) or compromised…
Drug-induced acute tubular necrosis is a primary cause of acute renal failure (ARF); it may result from the use of such agents as aminoglycosides, amphotericin B, and radilocontrast media. To reduce the risk of aminoglycoside toxicity, prescribe the…
The interpretation of acid-base data can be greatly facilitated by applying five rules: (1) use the blood gas to identify acidemia or alkalemia, (2) determine whether the underlying cause of acidemia or alkalemia is respiratory or metabolic, (3)…
BACKGROUND. Between 15% and 25% of children who visit primary care physicians have emotional, behavioral, or psychiatric problems that affect their functioning. The majority of these children are treated by primary care physicians. The purpose of…
This essay begins with a discussion of the primacy of the nuclear family in American drama. Our best playwrights have been strikingly preoccupied with domestic life, consistently portraying the family as a dream of solidarity and a nightmare of…
BACKGROUND. There is a national trend to deinstitutionalize mentally retarded adults, placing them in community residential settings. As a result, community-based primary care physicians will assume responsibility for their medical care. Primary care…
This study describes the results of a retrospective review of patients' charts who had an advanced directive (AD) and who were hospitalized in a tertiary, acute care teaching hospital. The purpose of the review was to understand from clinical,…
The cholesterol 7alpha-hydroxylase gene (CYP7A) is transcriptionally regulated by a number of factors, including hormones, bile acids, and diurnal rhythm. Previous studies have identified a region from nucleotides (nt) -74 to -55 of the rat CYP7A…
Decisions which determine the duration and outcome of terminal care should be influenced by patient autonomy. Studies suggest, however, that end-of-life decision-making is more complex than a single principle and that physicians may be responsible…
OBJECTIVE: Definition of the nature of calcaneal "erosions" in sickle cell anemia. METHODS: Skeletons of individuals demonstrated to have had sickle cell anemia were examined for the presence of calcaneal surface discontinuity. RESULTS: Calcaneal and…
Ovariectomized rats treated or not with an estradiol pellet were subjected to an unilateral intrastriatal infusion of 6-hydroxydopamine (6-OHDA). Various parameters of nigrostriatal dopaminergic function as derived from measurements of dopamine and…
A method of evaluating trend (positive or negative) in 2 x K ordered tables is suggested for cases in which the scores for the first (K-1) categories are known a priori but the score for the last category is not known. Such a category is termed as…
OBJECTIVE: To make clinically relevant recommendations for electrocardiogram (ECG) testing among psychiatric patients, the study examined the practice of ordering ECGs for this population. METHODS: The records of 4,045 patients consecutively admitted…
We evaluated the ability of canine isolated nonperfused lung lobes to absorb fluid from their air spaces by simultaneously measuring alveolar liquid clearance (ALC) in three lobes removed from the same dog. Autologous plasma was instilled in the air…
Arterial pressure, cardiac sympathetic tonus (ST), and heart rate (HR) are reduced after a single bout of dynamic exercise in spontaneously hypertensive rats (SHR). To test if the arterial baroreflex is required for these postexercise responses,…
The influence of daily spontaneous running (DSR) on the sympathetic (SC) and parasympathetic components of the arterial baroreflex control of heart rate (HR) was examined in 16 female Long Evans rats [8 sedentary (SED) and 8 DSR]. After
"Central command" may initiate the sympathoexcitatory responses at the onset of exercise by shifting the operating point of the arterial baroreflex toward higher pressures. Daily exercise (DE) attenuates the sympathoexcitatory responses to submaximal…
