Purpose Lymph node (LN)-negative breast cancer tumors >= 5 cm occur infrequently, and their optimal management is not well defined. In this study, we assess patterns of locoregional failure (LRF) in LN-negative patients who underwent mastectomy,…
A recent lack of availability of the anesthetic agent methohexital in the United States allowed for a naturalistic study of the efficacy and the adverse effects of alternatives. Methohexital, propofol, and thiopental were compared as anesthetic…
Some investigators have reported that endogenous beta-adrenoceptor tone can provide protection against acute lung injury. Therefore, we tested the effects of beta-adrenoceptor inhibition in mice with acute Escherichia coli pneumonia. Mice were…
This article provides an overview of health promotion and disease and injury prevention concepts. It provides an emergency medicine perspective and reviews approaches that can be used in the emergency department. It discusses examples of innovative…
Prox1, an early specific marker for developing liver and pancreas in foregut endoderm has recently been shown to interact with alpha-fetoprotein transcription factor and repress cholesterol 7alpha-hydroxylase (CYP7A1) gene transcription. Using a…
The gene encoding cholesterol 7alpha-hydroxylase (CYP7A1) is tightly regulated to control bile acid synthesis and maintain lipid homeostasis. Recent studies in mice suggest that bile acid synthesis is regulated by the fasted-to-fed cycle, and fasting…
Bone cell-substrate interactions are important to understand in the design, selection, and surface modification of bone implants. To gain insight into such interactions, substrates designed with surface species approximating the physiological…
BACKGROUND. Nonpharmacologic interventions, such as distraction, have been shown to be powerful adjuncts in reducing pain and anxiety in children with both acute and chronic painful conditions. There are no controlled studies evaluating these…
Background: Foot burns in children often result from contact with heated surfaces due to high ambient temperatures during summer in the southwestern United States. The objective of this study was to describe the unique cause and clinical…
A cascade of events follows binding of an agonist ligand to the tachykinin NK(1) receptor. These events include activation of multiple signal transduction pathways as well as cellular modulation of receptor function by the process of desensitization.…
A complex plasma disc (CPD) is a stable two-dimensional arrangement of it particles, each with mass in and charge q, confined by a parabolic well and interacting through a shielded Coulomb force (i.e. a Yukawa potential). It is shown that the…
Three experiments are presented in which dopamine (DA) responses from superfused striatal tissue of orchidectomized (ORCH) mice treated or not with testosterone (T) are compared. In experiment 1, potassium-stimulated DA output was significantly…
The transcription of the cholesterol 7 alpha-hydroxylase gene (CYP7A1) is greatly decreased in cholesterol-fed rabbits. To determine whether the molecular structure of the promoter is responsible for this downregulation, we cloned the rabbit CYP7A1…
Objectives: The aim of this study was to correlate the anatomic and clinical significance of the prepubic course of dorsal nerve of penis and its groove on the pubic bone from the perspective of the surgeon. Methods: The course of the dorsal nerve of…
OBJECTIVES: To describe the prevalence of depressive symptoms in adolescents presenting to the emergency department (ED) and to describe their demographics and outcomes compared with adolescents endorsing low levels of depressive symptoms. METHODS:…
Adults who exercise regularly have better health, but only 15% of U.S. adults engage in regular exercise, with some social groups, such as people with lower incomes and women, having even lower rates. This study investigates the rate at which…

Fluorescent retrograde tracers were used to identify the cells in auditory cortex that project directly to the cochlear nucleus (CN). Following injection of a tracer into the CN, cells were labeled bilaterally in primary auditory cortex and the…
The inferior colliculus (IC) and superior olivary complex (SOC) are important sources of descending pathways to the cochlear nucleus. The IC and SOC are also targets of direct projections from the auditory cortex but it is not known if cortical axons…
The present research indicated substantial variation within the 5 RIASEC (Realistic, Investigative, Artistic, Social, Enterprising, Conventional) profiles obtained by each of 99 individuals who responded to the same 5 interest inventories. The…
As part of a broader effort to identify postreceptor signal regulators involved in specific diseases or organ adaptation, we used an expression cloning system in Saccharomyces cerevisiae to screen cDNA libraries from rat ischemic myocardium, human…
Background/Aims: Hemodialysis patients are often hospitalized, during which time they require continuity of care in the inpatient setting. The goal of the present study was to evaluate the clinical outcomes associated with a conversion algorithm from…
PURPOSE: To evaluate the effects of 2 noise reduction techniques on the auditory brainstem response (ABR). METHOD: ABRs of 20 normal hearing adults were recorded during quiet and active behavioral conditions using 2 stimulus intensity levels. Wave V…

Chronic mucocutaneous candidiasis (CMC) is characterized by recurrent candidal infections of the mucous membranes, nails, and skin. Systemic involvement is rare. CMC in adults with coexistent thymoma, benign or malignant, is well-known and is often…
Objectives. Because several experimental studies have demonstrated that cyclic adenosine monophosphate generation following beta-adrenoceptor activation can markedly stimulate alveolar fluid clearance, we determined whether the endogenous levels of…
Actinomycosis, originally classified as a fungus, is now considered a branching bacteria. Although jaw involvement often presents with classic pathognomonic signs, postcranial disease has not been so characterized. Affected bones from individuals…
Bejel clearly has a long history in the Middle East and the Sudan, but was it transmitted to Europe? As the major manifestation of bejel is presence of periosteal reaction in 20-40% of afflicted populations, absence of significant population…
The purpose of this study was to assess birds as a potential model for osteoarthritis. Compromised by confounding factors, it has not been possible to clearly delineate causation in humans. Nonhuman mammals manifest osteoarthritis in the natural…
The hypothesis of disease-related large mammal extinction has new support. A unique pathologic zone of resorption was first noticed in a Hiscock Mammut americanum metacarpal. The pathognomonic zone of resorption was present in fifty-nine (52%) of 113…
