In rat thoracic aorta, contractile responses to arginine vasopressin are two-fold higher in females than in males. To determine the roles of extracellular and intracellular Ca2+ in this sexual dimorphism in vascular function, vascular reactivity and…
Amiloride is an inhibitor of urokinase plasminogen activator (uPA), an essential component of the plasminogen/plasmin enzyme system. Inhibition of uPA prevents the conversion of plasminogen to tumor cell surface bound plasmin which is required for…
Infections caused by M. pneumoniae, C. pneumoniae, and Legionella spp. are important causes of community-acquired pneumonia (CAP). In the past decade, considerable new information has come to light concerning these organisms. Despite this, debate…
Patient size has been suggested as a risk factor in kidney transplantation. We have followed a recipient of a cadaver kidney who became massively obese (232 kg, 511 lbs) 5 years posttransplantation. He has maintained stable renal function with no…
Cholesterol 7 alpha-hydroxylase catalyzes the first and rate-limiting step in the conversion of cholesterol to bile acids in the liver. Previously, we have identified two bile acid response elements located in nt -74 to -54 (BARE-I) and -148 to -118…
Research to initially construct and evaluate the Decisional Process Inventory (DPI; Hartung, 1994) revealed its potential use for assessing progress and problems in career decision making (Hartung, 1995). Advancing this preliminary area of instrument…
Career-Development Assessment and Counseling (C-DAC) systematically bridges career theory and practice. Integrating differential, developmental, and phenomenological methods, the C-DAC model uses a comprehensive career assessment battery to help…
BACKGROUND. Although many treatment modalities have been described for xanthelasma palpebrarum, no single technique has emerged as dominant. OBJECTIVES. Our purpose was to review the various therapeutic modalities for xanthelasma anti to assess the…
The present study examined whether measurement of hemoglobin-acetaldehyde (HbA1-AcH) using an improved methodology may be useful as a biological marker of alcohol abuse. Red blood cell hemolysates of 182 patients consecutively admitted to the drug…
The authors identified the origin of a high-density artifact with mammography film. An acrylic ramp phantom (thickness, 0-7 cm) was used to create a continuously variable radiation exposure. A perturbation in the curve of optical density versus…
The present study addresses the specificity of lyric osseous impact for distinguishing among metastatic cancer, tuberculosis, and fungal disease. Osseous impact is used in this manuscript as a convention to describe the macroscopic appearance of…
Gallbladder duplication can present a significant challenge to the laparoscopic surgeon, primarily due to difficulties with diagnosis and recognition. Previous reports of attempted laparoscopic cholecystectomy in patients with gallbladder duplication…
Previous research has demonstrated that the antinociceptive efficacy of opioids decreases with advancing age. This study utilized radioligand binding techniques to determine if this decline is due to a change in the receptor density (Bmax) and/or…
Cell-matrix interactions are important in the development of the avian cornea. Type VI collagen is present within the periocular mesenchyme prior to the migration of cells into the corneal stroma and is abundant in the mature stroma. Whether the…
A prospective, descriptive study is reported on the use and success of ultrasound-assisted internal jugular central vein catheterization (CVC) in the emergency department (ED). In patients not in cardiac arrest who had an indication for internal…
Monoamine-activated alpha2-macroglobulin (alpha2M) was shown to reduce the dopamine concentration in corpus striatum of adult rat brains and inhibit other neuronal functions in vivo and in vitro. As brain-derived neurotrophic factor, neurotrophin-4,…
Monoamine-activated alpha(2)-macroglobulin (alpha(2)M) was shown to reduce the dopamine concentration in corpus striatum of adult rat brains and inhibit other neuronal functions in vivo and in vitro. As brain-derived neurotrophic factor,…
Previous studies have implicated human alpha-2-macroglobulin (alpha2M) as a potential regulator of neuronal development and function. Rat alpha-1-macroglobulin (alpha1M) and acute-phase alpha-2-macroglobulin (alpha2M) are murine homologues of human…
The current study has documented changes in the ultrastructure as well as in the intranucleolar distribution of rDNA and rRNA in RT4 (human transitional cell bladder carcinoma) cell nucleoli following a 3-h exposure to toxic doses of 50 microM…
An ectopic thyroid goiter was found in a 58-year-old woman who presented with abdominal and low back pain, diarrhea, and generalized weakness. Initial workup, including abdominal CT scan, revealed a mass extending from the duodenum to the porta…
Anecdotal evidence suggests that the foramina of the cribriform plate which transmit cranial nerve I decrease in size with age, but this finding has never been supported with quantitative data. It has also been observed that olfactory function…
Although cholelithiasis is uncommon in children, its laparoscopic treatment has progressively become more popular among pediatric surgeons. This is due in part to the fact that compared with the open technique, laparoscopic treatment is less invasive…
Based mainly on the simplicity of its calculation, the urea reduction ratio (URR) has been suggested as an alternative to urea kinetic modeling (Kt/V) as a measure of hemodialysis adequacy. However, recent studies have raised questions concerning the…
