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

Effective production of hydrogen negative ions (H-) is one of the important issues in high power neutral beam injection (NBI) for fusion experimental devices. Cesium (Cs) vapor is seeded in the H- sources to enhance the H- production rate, which depends

Fundamental Ion-Surface Interactions in Plasma Thrusters [PDF]
Ion thrusters offer the potential to enable many future interplanetary robotic missions presently under consideration by NASA. To realize the benefits offered by these low thrust devices, the sputtering mechanisms that are responsible for the ...

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

A side extraction PIG negative ion source with a permanent magnet
A side extraction PIG ion source with a permanent magnet is introduced, which can be used not only for producing miliampere positive ion beams, but also for direct extraction of negative ions of some elements with larger electron affinity.

Optimization of Ion Beam Elements Using Mathematical Transport Formalism
In the study we report the features and ideal stable operating conditions of the ion source and the accelerator’s beam behavior of a nuclear microprobe at a laboratory for accelerator-based science (LABS) laboratory, i.e., iThemba LABS, South Africa ...

Systemic dysregulation of apolipoproteins in amyotrophic lateral sclerosis serum
Amyotrophic lateral sclerosis (ALS) is a fatal disease that damages motor neurons. This study found that people with ALS show significant changes in blood fats and the proteins that carry them. Several apolipoproteins were higher, lipid balances were altered, and normal protein–lipid relationships were disrupted.

Visualization of H? Dynamics in Extraction Region of Negative-Ion Source by Hα Imaging Spectroscopy
We developed a new imaging spectroscopy diagnostic tool for Hα emission and installed it on a negative hydrogen ion (H?) source to investigate the H? dynamics in the extraction region.
