Effectiveness of two and three doses of COVID-19 mRNA vaccines against infection, symptoms, and severity in the pre-omicron era: A time-dependent gradient
(
Elsevier
, 2024 , Article)
BackgroundVaccines were developed and deployed to combat severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. This study aimed to characterize patterns in the protection provided by the BNT162b2 and ...
Pathogenic Homocystinuria-Associated T236N Mutation Dramatically Alters the Biochemical Properties of Cystathionine Beta-Synthase Protein
(
MDPI
, 2024 , Article)
Background: Cystathione beta-synthase (CBS) T236N is a novel mutation associated with pyridoxine non-responsiveness, which presents a significant difficulty in the medical treatment of homocystinuria. Reported severe ...
Polyaniline/polyvinyl alcohol blends: Effect of sulfonic acid dopants on microstructural, optical, thermal and electrical properties
(
Elsevier
, 2014 , Article)
This correspondence reports the preparation and performance of different polyaniline–polyvinyl blends (PANI–PVA) doped with sulfonated acids. PANI is prepared by in situ dispersion polymerisation, and a subsequent extensive ...
High performance sulfonic acid doped polyaniline–polystyrene blend ammonia gas sensors
(
Springer Nature
, 2016 , Article)
In this work, we present a method of preparation and sensing measurement of four camphorsulfonic acid (CSA) doped polyaniline–polystyrene blends (PANI–PS), where PANI is obtained by dispersion polymerization and blending ...
Surface layer modification of ion bombarded HDPE
(
Elsevier
, 2004 , Article)
Press-moulded, high density polyethylene (HDPE) samples were subjected to ion bombardment and effects of the modification studied. He+ ions of energy 100 keV or Ar+ ions of energy 130 keV were applied in the range of dose ...
Reduced erbium-doped ceria nanoparticles: One nano-host applicable for simultaneous optical down- and up-conversions
(
Springer Nature
, 2014 , Article)
This paper introduces a new synthesis procedure to form erbium-doped ceria nanoparticles (EDC NPs) that can act as an optical medium for both up-conversion and down-conversion in the same time. This synthesis process results ...
Improved electrical conductivity of carbon/polyvinyl alcohol electrospun nanofibers
(
Hindawi
, 2015 , Article)
Carbon nanofibers (CNFs) gained much interest in the last few years due to their promising electrical, chemical, and mechanical characteristics. This paper investigates a new nanocomposite composed of carbon nanofibers ...
Temperature and electric field effects on the dielectric dispersion of modified polyvinyl chloride
(
Elsevier
, 2003 , Article)
The effect of electric field on the dielectric dispersion of modified polyvinyl chloride (PVC) has been investigated. The applied direct current (DC) field strength was ranging from 0 to 104 V cm−1. The complex permitivity ...
SARS-CoV-2 infection triggers more potent antibody-dependent cellular cytotoxicity (ADCC) responses than mRNA-, vector-, and inactivated virus-based COVID-19 vaccines
(
Wiley
, 2024 , Article)
Neutralizing antibodies (NAbs) are elicited after infection and vaccination and have been well studied. However, their antibody-dependent cellular cytotoxicity (ADCC) functionality is still poorly characterized. Here, we ...
Core Body Temperatures in Intermittent Sports: A Systematic Review
(
Springer Nature
, 2023 , Article)
Background: Hyperthermia (and associated health and performance implications) can be a significant problem for athletes and teams involved in intermittent sports. Quantifying the highest thermal strain (i.e. peak core body ...
