Redox driven B12-ligand switch drives CarH photoresponse

open access: yesNature Communications, 2023
CarH is a coenzyme B12-dependent photoreceptor involved in regulating carotenoid biosynthesis. How light-triggered cleavage of the B12 Co-C bond culminates in CarH tetramer dissociation to initiate transcription remains unclear. Here, a series of crystal

Controlling Chemical Reactions in Confined Environments: Water Dissociation in MOF-74

open access: yesApplied Sciences, 2018
The confined porous environment of metal organic frameworks (MOFs) is an attractive system for studying reaction mechanisms. Compared to flat oxide surfaces, MOFs have the key advantage that they exhibit a well-defined structure and present significantly

Modeling Dissociation-Vibration Coupling with the Macroscopic Chemistry Method [PDF]

open access: yesAIP Conference Proceedings, 2005
We test the recently developed macroscopic approach to modeling chemistry in DSMC [Lilliley & Macrossan, Physics of Fluids, 16(6), 2054-2066 (2004)], by simulating the flow of rarefied dissociating nitrogen over a blunt cylinder. In this macroscopic method, chemical reactions are decoupled from the collision routine.

The cytoskeletal control of B cell receptor and integrin signaling in normal B cells and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Electrolytic properties of carbonic acid solutions and innovative methods of operational control of water quality such as condensation at TPP

open access: yesAdvanced Engineering Research, 2015
The work objective is to improve the operational conductometric vapor quality control at the thermal power plants. To this end, methods identifying СО2 concentrations in the vapor under the neutral aqueous-chemical mode without ammonia addition are ...

Current estimates of K1* and K2* appear inconsistent with measured CO2 system parameters in cold oceanic regions [PDF]

open access: yesOcean Science, 2020
Seawater absorption of anthropogenic atmospheric carbon dioxide (CO2) has led to a range of changes in carbonate chemistry, collectively referred to as ocean acidification.

Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Model for acid-base chemistry in nanoparticle growth (MABNAG) [PDF]

open access: yesAtmospheric Chemistry and Physics, 2013
Climatic effects of newly-formed atmospheric secondary aerosol particles are to a large extent determined by their condensational growth rates. However, all the vapours condensing on atmospheric nanoparticles and growing them to climatically relevant ...
