Using survival curves for comparison of ordinal qualitative data in clinical studies [PDF]

open access: yesarXiv, 2009
Background and Objective: The survival-agreement plot was proposed and improved to assess the reliability of a quantitative measure. We propose the use of survival analysis as an alternative non-parametric approach for comparison of ordinal qualitative data. Study Design and Setting: Two case studies were presented.

Evaporation‐Enhanced Redox Cycling for Rapid Detection of Attomolar SARS‐CoV‐2 Virions Using Nanolithography‐Free Electrochemical Devices

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents microfabricated electrochemical sensors for detecting ultralow viral particles counts through evaporation‐enhanced redox cycling (E2RC). To achieve sub‐micrometer gap in interdigitated microelectrodes, a scalable, nanolithography‐free fabrication method is developed.

Epidemiology, diagnosis, vaccines, and bibliometric analysis of the 100 top-cited studies on Hepatitis E virus

open access: yesHuman Vaccines & Immunotherapeutics, 2021
Introduction In low-income countries, Hepatitis E infection is a common cause of acute hepatitis. So far, only two recombinant vaccines (rHEV and HEV 239) have been developed against Hepatitis E virus (HEV).

A Physiologically-Based Flow Network Model for Hepatic Drug Elimination I: Regular Lattice Lobule Model [PDF]

open access: yesarXiv, 2011
We develop a physiologically-based lattice model for the transport and metabolism of drugs in the functional unit of the liver, called the lobule. In contrast to earlier studies, we have emphasized the dominant role of convection in well-vascularized tissue with a given structure. Estimates of convective, diffusive and reaction contributions are given.

Center-specific causal inference with multicenter trials: reinterpreting trial evidence in the context of each participating center [PDF]

open access: yesarXiv, 2021
In multicenter randomized trials, when effect modifiers have a different distribution across centers, comparisons between treatment groups that average over centers may not apply to any of the populations underlying the individual centers. Here, we describe methods for reinterpreting the evidence produced by a multicenter trial in the context of the ...

Enhanced Epithelial Cell Uptake of Glycol Chitosan‐Coated PLGA Nanoparticles for Oral Drug Delivery

open access: yesAdvanced Therapeutics, EarlyView.
Here, glycol chitosan (GC)‐coated PLGA NPs are developed to enhance oral drug delivery by enabling dual‐pathway endocytosis via clathrin‐ and caveolae‐mediated mechanisms. Alginate layering coating on GC‐PLGA further improves oral insulin delivery, achieving sustained glucose reduction in diabetic mice.

Characteristics of the Clinical Course of Autochthonous Hepatitis E in the Central Region of Russia

open access: yesЖурнал инфектологии, 2014
The records of total 123 patients with hepatitis E on treatment in the infectious diseases hospital in the city of Belgorod were reviewed. Diagnosis – «acute hepatitis E» was based on the generally accepted criteria: biochemical analysis, etiological ...
