Can visual interpretation of NucliSens graphs reduce the need for repeat viral load testing?

Handling for Viral Load Testing and Surveillance

RNA remains the most informative and accurate biomarker for human immunodeficiency virus type 1 load diagnostics and for surveillance of drug resistance markers. Viral load testing by nucleic acid amplification currently is a complex and expensive test that is restricted to centralized laboratory testing. Successful extension of centralized viral load testing to rural or remote settings is a ma...

Testing student interpretation of kinematics graphs

Recent work has uncovered a consistent set of student difficulties with graphs of position, velocity, and acceleration versus time. These include misinterpreting graphs as pictures, slope/height confusion, problems finding the slopes of lines not passing through the origin, and the inability to interpret the meaning of the area under various graph curves. For this particular study, data from 89...

Concurrent working memory load can reduce distraction.

People have difficulty performing two tasks at once. For example, maintaining items in working memory (WM) makes people more distractible. However, different types of WM load may have different effects on attentional selection depending on whether WM load overlaps with mechanisms involved in target or distractor processing. Three experiments examined the effect of concurrent WM load on Stroop t...

Viral load testing in resource-limited settings.

Can Viral Load Predict Liver Histology in Patients With Chronic Hepatitis B?

Introduction: Hepatitis B virus (HBV) infection is a global public health problem. Serum HBV DNA measurement is a non-invasive test that predicts the liver disease progression. The aim of this study was to determine the HBV DNA level and look for a relation between the HBV DNA level and liver histology. Methods: This was a cross sectional study on chronic...
