Survey data were used to study the association of methadone maintenance and needle-sharing. An ordinal scale of HIV risk was derived from the number of persons from whom subjects reported accepting a used needle and syringe in the 6 months prior to…

STUDY OBJECTIVES: To evaluate the effects of L-arginine on acute pulmonary embolism (APE)-induced pulmonary hypertension and increases in lung matrix metalloproteinase (MMP)-2 and MMP-9 activities. DESIGN: Prospective trial. SETTING: University…

Introduction: Clinical signs have been always of significant value in the diagnosis of appendicitis. Specific clinical signs are elicited coupled with routine laboratory and radiological investigations in making the diagnosis of acute appendicitis.…

We report the first use of differential terahertz time-domain spectroscopy for bioaffinity sensing. Binding is observed by measuring the transmission of a thin layer of biotin bound to the sensor protein avidin. We demonstrate the THz wave…
-
We present the fabrication and characterization of a nano-scale sensor made of amorphous silicon for the label-free, electronic detection of three classes of biologically important molecules: ions, oligonucleotides, and proteins. The sensor…
-
A label-free sensing approach for the label-free characterization of genetic material with terahertz (THz) electromagnetic waves is presented. Time-resolved THz analysis of polynucleotides demonstrates a strong dependence of the complex refractive…

OBJECTIVE: To compare the absorption of carbon-13(13C) acetate-enriched nutrients with D-xylose absorption. DESIGN: Prospective cohort observational study. SETTING: Surgical intensive care unit of a university hospital. PATIENTS: A total of 24…

64Cu shows promise as both a positron emission tomography imaging and radiotherapeutic radionuclide due to its half-life (T(1/2) = 12. 7 h), decay characteristics (beta(+) 19%; beta(-) 40%), and the capability to produce it on a large-scale with…

INTRODUCTION: The monoclonal antibody (mAb) L8A4, reactive with the epidermal growth factor receptor variant III (EGFRvIII), internalizes rapidly in glioma cells after receptor binding. Combining this tumor-specific mAb with the low-energy…
-
Over the past decade, several laboratory tests have been introduced to veterinary medicine that allow the minimally invasive assessment of diseases of the gastrointestinal tract, liver, and pancreas. Although some of those tests have limited…
-
PURPOSE: The Biotrainer and Actitrac activity monitors (IM Systems) offer potential research advantages over existing accelerometry-based activity monitors, but they have not been tested under controlled conditions. The purpose of this study was to…

We evaluated laboratory methods to confirm a clinical diagnosis of dengue. Acute sera were collected from personnel (n = 414) supporting the United Nations Mission in Haiti and presenting with febrile illness consistent with dengue fever or no…
-
Rising numbers of immunocompromised patients have led to an ever-increasing population at risk of invasive fungal disease. Much has been achieved in the laboratory diagnosis of these infections, such as advances in blood culture systems, and the…
-
This article examines the use of laboratory tests for managing mechanical ventilation. Blood gas analysis is a common test widely used for this purpose, and this is evaluated in detail. Other tests, however, provide valuable insight into the…
-
The clinical manifestations of dengue hemorrhagic fever (DHF) consist of three successive stages: febrile, toxic and convalescent. The toxic stage is the critical period, which may manifestas circulatory disturbance or even profound shock in some…
-
Quality control plays a vital role helping to ensure the reliability of laboratory test results. The application of statistical quality control has been a component of laboratory medicine for approximately 50 years. Many of the control rules based…
-
The diagnosis of disseminated intravascular coagulation (DIC) relies on clinical signs and symptoms, identification of the underlying disease, the results of laboratory testing, and differentiation from other pathologies. The clinical features…
-
There are several tests available to evaluate renal function. Because the kidney has such complex and varied functions, no one test can adequately measure them. A rough measure of renal function can be obtained by examining the constituents of the…
-
Laboratory tests provide the most definitive information for diagnosing and managing many diseases, and most patients look to laboratory tests as the most important information from a medical visit. Most patients who have rheumatoid arthritis (RA)…

Clinical diagnosis of infectious diseases in Africa has been associated with increased misdiagnosis and mortality, but when laboratory testing is available, it remains underused. We retrospectively compared infectious diagnoses, test results,…
