The role of antibody indexes in clinical virology [PDF]
Clinical Microbiology and Infection, 2021 Serological techniques are an essential part of the diagnostic tools used in clinical virology. Among these techniques, antibody indexes are not novel, but do require specific expertise. Their niche has expanded substantially in recent years due to increasing evidence of their performance to diagnose viral infections.This narrative review describes the

RESISTANCE OF FOUR DIFFERENT LOCAL HYBRID CHICKENS TO INFECTIOUS BURSAL DISEASE INFECTION
The Iraqi Journal of Veterinary Medicine, 2021 Four hundred, one day old chicks, of four hybrids, were divided into four groups, reared on the floor for ten weeks. The hybrids were vaccinated with live IBD vaccine at 14, 35, 56 days. Maternal antibody titers, antibody titer after each vaccination and

Improved method to calculate the antibody avidity index [PDF]
Journal of Clinical Laboratory Analysis, 2007 AbstractThe methods currently used to determine the immunoglobulin avidity index (AI) require the choice of a reference point in the ELISA titration curve. Since both curves, with and without denaturating reagents, seldom run in parallel, the AI value becomes highly dependent on this reference.

The realization of an integrated Mach-Zehnder waveguide immunosensor in silicon technology [PDF]
, 1997 We describe the realization of a symmetric integrated channel waveguide Mach-Zehnder sensor which uses the evanescent field to detect small refractive-index changes (¿nmin ¿ 1 × 10¿4) near the guiding-layer surface.

Antibody indexes in COVID-19 convalescent plasma donors: Unanswered questions
Clinics, 2021 Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is characterized by high contagiousness, as well as variable clinical manifestations and immune responses. The antibody response to SARS-CoV-2 is directly related to viral clearance and the antibodies' ability to neutralize the virus and confer long-term immunity.

Refractive index and layer thickness of an adsorbing protein as reporters of monolayer formation [PDF]
, 1995 A method is presented for a separate real-time determination of refractive index and layer thickness of an adsorbing thin layer. The changing angular deflections of TE and TM modes in a dedicated planar waveguide structure are measured. A resolution of 0.
