Acceptor‐Donor‐Acceptor Systems Based on Indacenodithiophene‐Extended Tetrathiafulvalene [PDF]

open access: yesEuropean Journal of Organic Chemistry
AbstractHere, we present a series of acceptor‐donor‐acceptor (A−D‐A) conjugated molecules incorporating an indacenodithiophene‐extended tetrathiafulvalene (IDT‐TTF) as the central electron‐donating moiety, functionalized with various lateral electron acceptors.

[4 + 2]-Cycloaddition Reactions between β-Acceptor-Substituted Enamines and 2-Vinylindole Radical Cations Acting as Hetero-Dienes

open access: yes, 2016
[4 + 2]-Cycloaddition reactions between 2-vinylindoles acting as hetero-dienes and β-acceptor substituted cyclic and acyclic enamines can be induced by formation of 2-vinylindole radical cations either via anodic oxidation or photoelectron transfer (PET)

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Mixed‐class J‐domain protein scaffolds promote expanded aggregate handling and multivalent Hsp70 engagement during functional disaggregase assembly

open access: yesFEBS Letters, EarlyView.
Protein aggregates threaten proteostasis and cell health. In human cells, Hsp70–J‐domain protein‐based disaggregases remove aggregates, but how they assemble remains unclear. Our biochemical findings show that DNAJA2‐ and DNAJB1‐containing disaggregase scaffolds enhance luciferase aggregate targeting, and that Hsp70 recruitment by both J‐domain ...

Knowledge, Attitude and Practice of Modern Contraceptives (especially Spacing Methods) in Acceptors and Non-acceptors of Tubectomy

open access: yesNational Journal of Community Medicine, 2018
Context: From National Health Policy 1983 to NHP 2017, three demographic goals are constantly persuaded:  to reduce CBR (Crude Birth Rate) to 21, NRR (Net Reproduction Rate) to 1 and raise the CPR (Couple Protection Rate) to at least 60%, which are not ...

Effect of Curvature and Placement of Donor and Acceptor Units in Cycloparaphenylenes: A Computational Study

open access: yes, 2020
Cycloparaphenylenes have promise as novel fluorescent materials. However, shifting their fluorescence beyond 510 nm is difficult. Herein, we computationally explore the effect on CPP photophysical properties of incorporating electron accepting and ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
