Combined 5‐aminolevulinic acid and ferric ammonium citrate treatment promotes hair follicle growth by activating dermal papilla cells

FEBS Open Bio, EarlyView.
5‐Aminolevulinic acid combined with ferric ammonium citrate (5‐ALA/FAC) stimulates dermal papilla cell activity and promotes hair follicle growth. The treatment enhances ERK and AKT signaling, increases hair‐inductive gene expression, and restores dermal papilla function suppressed by dihydrotestosterone and oxidative stress, resulting in enhanced hair

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Why Bond Critical Points Are Not “Bond” Critical Points

Chemistry – A European Journal, 2018
AbstractEquating (3,−1) critical points (CPs), derived from the topological analysis of the electron densities, to chemical bonds has triggered a lot of confusion in recent years. Part of this confusion stems from calling these CPs “bond” CPs (BCPs). While the origin of this terminology is traceable to the late seventies and beginning of eighties, when

Critical-point dewetting

Physical Review B, 1987
Already within Landau theory with short-ranged substrate-adsorbate forces, complete wetting is not necessary near critical points. Preferential adsorption, but only partial wetting all the way to the critical point, and even critical-point dewetting are possible.

Critical Point in Complex Plasmas

Physical Review Letters, 2006
The occurrence of liquid-vapor phase transition and the possible existence of a critical point in complex plasmas--systems that consist of charged micrograins in a neutralizing plasma background--is investigated theoretically. An analysis based on the consideration of the intergrain interaction potential suggests that under certain conditions systems ...

Percolation and critical points

Journal of Physics: Condensed Matter, 2001
The interplay between critical percolating clusters and critical points in physical systems and models is reviewed. The main emphasis is given to systems such as colloids and gels. Much information on the main mechanism leading to percolation in correlated systems can be obtained from the study of the Ising model.

The φ4 Critical Point

1981
To fix the notation, we consider the interaction $$V\left( \phi \right) = \lambda \phi ^4 + \sigma \phi ^2 - \mu \phi $$ (17.1.1) with λ, σ, and μ real and 0 0.)

This is the critical point

Physics World, 2020
Having written the Critical Point column in Physics World for 20 years, Robert P Crease still worries that physicists don't realize why the humanities are so important

Critical Points of Functionals

2004
In the last section of the preceding chapter, we have already seen examples of how solutions to certain nonlinear equations could be obtained as critical points of appropriate functionals.
