Prolonged or repeated activation of many G protein-coupled receptors induces rapid desensitization followed by a period during which receptors are resensitized. In this study, concanavalin A (Con A) and monensin were used to investigate the…
Resolution of pulmonary edema involved active transepithelial sodium transport. Although several of the cellular and molecular mechanisms involved are relatively well understood, it is only recently that the regulation of these mechanisms in injured…
This review examines the literature on personality and medical specialty choice. First, it describes studies categorized by medical specialties that to date have used the same measures: Adjective Check List, California Psychological Inventory,…
Optimal information that should be included in ultrasound (US) heel bone mineral density (BMD) reports is not known. If additional information about further evaluation of patients with low heel BMD were included in reports, would responses for…
The decision of stressed cells to die or to survive is made by integrating signals at different levels through multiple check points. However, initiation and continued progression toward cell death by apoptosis in cancer cells may be blocked by…
A 7-year-old girl was seen because of a 2-month history of an expanding patch of pruritus and scaling just below her umbilicus (figure 1). The patient also complained of a generalized rash on her arms and legs that had been present for 10 days.…
Hypothesis: Mathematical methods and their derivatives have practical applications to oncology. They can be used to describe fundamental aspects of tumor behavior, such as loss of genetic stability, tumor growth, immunologic identity, genesis of…
Human pregnancy zone protein (PZP) is a major pregnancy-associated plasma protein closely related to human alpha(2)-macroglobulin (alpha(2)M). It has been demonstrated that monoamine-activated forms of human and rat alpha(2)M and rat alpha(2)M can…
Bile acids derived from cholesterol and oxysterols derived from cholesterol and bile acid synthesis pathways are signaling molecules that regulate cholesterol homeostasis in mammals. Many nuclear receptors play pivotal roles in the regulation of bile…
At the time of parturition (fetal delivery) the uterine cervix must "ripen," becoming soft, pliable, and dilated to accommodate the fetus' delivery. The fundamental processes underlying cervical ripening remain poorly understood. Knowledge that…
The temptation of using drugs and supplements as shortcuts to improving athletic performance or even to enhance appearance is very seductive to adolescents. This age group is often characterized by a desire for quick results and a lack of concern for…
Fungal infections of total joint arthroplasty are uncommon complications, and most cases have been associated with Candida species. In this article, we present a case in which a total hip arthroplasty was infected with Rhodotorula minuta.…
Study design: Case reports and survey of literature. Objective: Case reports of two women with tuberculosis (TB) of the spine (Pott's disease) presenting with severe back pain and diagnosed as compression fracture are described. Physicians should…
We reported previously that mice lacking one brain-derived neurotrophic factor (BDNF) allele demonstrate elevated striatal dopamine (DA) concentrations but impaired behavioral responses involving the nigrostriatal dopaminergic (NSDA) system. To test…
Methamphetamine (MA)-related deaths and nigrostriatal dopaminergic (NSDA) neurotoxicity are greater in males. The exact basis for this gender difference is not known, but data, which show that estrogen (E) can function as a protectant of both the…
In Part 1 of this report, we review data on the effects of estrogen (E), the anti-E tamoxifen (TMX), and testosterone (T) on methamphetamine (METH)-induced neurotoxicity in female and male CD-1 mice. Treatment of gonadectomized females with a…
Since estrogen exerts wide ranging effects within the central nervous system, it is important to investigate the sites and actions of this gonadal steroid hormone at extra-hypothalamic locations. In the present report, the effects of estrogen upon…
During corneal development, neural crest derivatives from the periocular mesenchyme migrate into the cornea and differentiate into corneal fibroblasts. During this time, these cells interact with a variety of extracellular matrices for proper…
BACKGROUND: Traumatic brain injury (TBI) is a leading cause of morbidity and mortality in trauma patients. Cerebral perfusion pressure (CPP) directed ICU management is recommended for patients with severe TBI. It, however, requires an invasive device…
The beta-lactam antibiotics (penicillins and cephalosporins) are commonly prescribed for the treatment of community-acquired pneumonia. However, Streptococcus pneumoniae, the most common etiologic agent of community-acquired pneumonia, has become…
The efficacy of a new pharmacokinetically enhanced formulation of amoxycillin/clavulanate (AMX/CA) 2000/125 mg, twice daily, designed to provide adequate levels of amoxycillin over the 12-h dosing interval to eradicate penicillin-resistant…
Knowledge about the conversion of the epithelium in the distal air spaces of the lung from secretion to absorption is imperative to the understanding of postnatal lung development; little such information is available in rats. Distal air space fluid…
