We evaluated the Ortho TRIO-Cytoronabsolute system for determining absolute CD4 counts. The CD4 counts in our blood specimens from 100 individuals ranged from 3 to 1,962; the percent CD4 ranged from 1.3 to 62.2, respectively. The TRIO system was…
BACKGROUND: Intense activation of the sympathetic nervous system or administration of high concentrations of catecholamines diminishes myocardial contractility and produces infarct-like lesions throughout the heart. This study was conducted to…
One hundred-twelve intracoronary stents (83 Palmaz-Schatz, 25 biliary, and 4 Gianturco-Roubin) were placed in 87 (51.7% male) patients aged greater than or equal to 70 years (70-93; mean 76.1) during a 1-year period. Ail stents were deployed using…
This is part of the series of practice guidelines commissioned by the Infectious Diseases Society of America through its Practice Guidelines Committee. The purpose of this guideline is to provide assistance to clinicians in the diagnosis and…
While patient care has been shifting to the ambulatory setting, the education of health care professionals has remained essentially hospital-based. One factor discouraging the movement of training into community-based ambulatory settings is the lack…
BACKGROUND: The core business of hospitals now requires, for both competitiveness and quality improvement reasons, that hospitals move beyond their physical and conceptual walls to form community partnerships. THE HOSPITAL'S ROLE AS A PARTNER IN…
In an effort to identify novel binding sites for cocaine and its analogs, we carried out binding studies with the high-affinity and selective ligand [125I]RTI-121 in rat frontal cortical tissue. Very low densities of binding sites were found.…

BACKGROUND: Consultation and referral are essential components of the practice of primary care. Despite this, little is known about the factors that contribute to the success of a referral. We examined the short-term outcomes of communication between…

Purpose. To evaluate the post-lumpectomy treatment of a nonpalpable, stage 1, T1b tumor, mammographically detected, in a 74-year-old woman without comorbidities. Methods. A Markov process, through 120 monthly cycles, was used to model patient…
The ability of hippocampal CA1 basal synapses to express N-methyl-D-aspartate (NMDA) receptor-independent long-term potentiation (non-NMDA LTP) was studied and compared to the simultaneously induced apical dendritic non-NMDA LTP. Non-NMDA LTP in…
Arterial pressure (AP), heart rate (HR), cardiac sympathetic tonus (ST), and parasympathetic tonus (PT) were determined in spontaneously hypertensive rats (SHR, 8 male and 8 female) and Wistar-Kyoto normotensive rats (WKY, 8 male and 12 female)…
The purpose of this study is to critically investigate the anatomy of the deep posterior compartment of the leg, Specifically, the relationship of the deep posterior compartment to the superficial posterior compartment and their Insertion onto the…
Bile acids are important physiological agents required for disposal of cholesterol and absorption of vitamins and fats. Bile acids are synthesized from cholesterol in the liver. Enterohepatic circulation of bile acids is very efficient and plays an…
Perforation from a solitary metastatic lesion of the small bowel is rare. We report a case of acute perforation with no evidence of metastatic disease within the abdomen. Resection of the small bowel was performed.
The gene encoding cholesterol 7alpha-hydroxylase (CYP7A), the rate-limiting enzyme in bile acid synthesis, is transcriptionally regulated by bile acids and hormones. Previously, we have identified two bile acid response elements (BARE) in the…

Outcome data were collected on 239 patients who underwent endoscopic release of the transverse carpal ligament. The procedure was performed on 333 hands in 239 patients. All patients had failed to respond to nonoperative management for carpal tunnel…
A physician may be called upon to evaluate disability in the roles of impartial judge of impairment, expert witness in a legal case, or treating physician. Critical to these processes are discernment between disability and impairment, an…
Striatal synaptosomes from ovariectomized rats were prepared to examine the effect of 17beta-estradiol on [3H]dopamine uptake. Estradiol inhibited [3H]dopamine uptake in a dose-dependent manner, with an IC50 of 7.2 microM. Use of identical…
The effects of varying doses of nicotine infusion upon spontaneous (basal) and subsequent potassium chloride-stimulated dopamine and 3,4-dihydroxyphenylacetic acid (DOPAC) output from superfused corpus striatal tissue fragments of male rats were…
In the present report, the peptides arginine vasopressin (AVP), oxytocin (OXT) or their respective antagonists were infused bilaterally into the olfactory bulb to assess their effects upon recognition responses. Recognition responses were determined…
Male rats were implanted bilaterally with cannulae directed at the olfactory bulbs and infused with either vehicle or 6-OHDA to selectively deplete norepinephrine concentrations at this site. At 5-7 days following this treatment, these animals…
PURPOSE: The development and maintenance of extracellular matrix architecture in the corneal stroma is associated with abundant type VI collagen deposition. This collagen has been implicated in mediating both cell-matrix and matrix-matrix…
