Kinetic studies on the reaction of formaldehyde with amines in the presence of sulfite [PDF]

open access: yes, 1999
The reaction of formaldehyde with amines with and without sulfite has been studied using anilines (RC(_6)H(_4)NH(_2)) and benzylamines (RC(_6)H(_4)CH(_2)NH(_2)). Reaction with anilines is known to produce aminomethanesulfonates, RC(_6)H(_4)NHCH(_2)SO(_3)(

Interpreting the effects of DNA polymerase variants at the structural level

open access: yesMolecular Oncology, EarlyView.
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

A comparative analysis of virucidal efficiency of biocide agents

open access: yesВопросы вирусологии, 2017
The main groups of biocide agents used for inactivation of bacteria and viruses were studied for their virucidal activity against enveloped (HIV, viral hepatitis C, influenza virus A) and non-enveloped viruses (poliovirus, adenovirus).

Dietary Maillard reaction products: implications for human health and disease [PDF]

open access: yes, 2009
When foods are heat processed, the sugars and lipids react with the proteins they contain via the Maillard and related reactions to form a wide range of products.

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

open access: yesFEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

open access: yesFEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.
