Concepts and Methods in the Study of the Qur’ān

open access: yesReligions, 2021
This paper addresses methodological issues in Qur’anic studies. At first, it intends to explain, through historiographical analysis, why methods proved fruitful in biblical and New Testament studies, such as form criticism and redaction criticism, have ...

Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

New Chloroprene Rubber/Styrene–Butadiene Rubber (CR/SBR) Blends Cross-Linked with Tin(II) Oxide (SnO): Curing Characteristics, Swelling Studies, Mechanical Properties, and Flame Resistance

open access: yesMolecules
This study aimed to investigate the properties of tin(II) oxide (SnO) as an unconventional cross-linking agent for chloroprene (CR) and styrene–butadiene (SBR) rubbers compositions. The use of tin(II) oxide results from the need to reduce the use of zinc

Developing scientific literacy with a cyclic independent study assisted CURE detecting SARS-CoV-2 in wastewater

open access: yesJournal of Microbiology & Biology Education, 2023
The COVID-19 pandemic has exposed a high level of scientific illiteracy and mistrust that pervades the scientific and medical communities. This finding has proven the necessity of updating current methods used to expose undergraduates to research.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Comparative Study on the Influence of Inorganic Pigments on the Thermomechanical and Combustion Performance of Different Elastomer Composites

open access: yesMolecules
Inorganic pigments are widely used in elastomer technology primarily as coloring agents; however, the broader effects of these additives on the structure–property relationships of rubber composites remain insufficiently understood, particularly across ...

Renewable Fabric Surface-Initiated ATRP Polymerizations: Towards Mixed Polymer Brushes

open access: yesNanomaterials, 2020
A totally new approach in the synthesis of mixed polymer brushes tethered on polyamide (PA) surfaces is presented herein. As a proof of concept, two types of homopolymers were synthesized in sequential surface-initiated atom transfer radical ...

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

open access: yesFEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

A novel green approach for reactive printing of cotton/cellulosic regenerated blended fabrics using trisodium nitrilotriacetate

open access: yesScientific Reports
Owing to their comfort, handle, and aesthetic characteristics, cotton fabrics will always be the first and primary choice for clothing and apparel. In recent years, regenerated cellulosic fabrics like bamboo, Tencel, and modal fabrics have had many ...
