Hair regrowth treatment efficacy and resistance in androgenetic alopecia: A systematic review and continuous Bayesian network meta-analysis.

Background: Androgenetic alopecia (AGA) affects almost half the population, and several treatments intending to regenerate a normal scalp hair phenotype are used. This is the first study comparing treatment efficacy response and resistance using standardized continuous outcomes.

Objective: To systematically compare the relative efficacy of treatments used for terminal hair (TH) regrowth in women and men with AGA.

Systemic Treatment with the Enteric Bacterial Fermentation Product, Propionic Acid, Reduces Acoustic Startle Response Magnitude in Rats in a Dose-Dependent Fashion: Contribution to a Rodent Model of ASD.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder, characterized by cognitive and sensorimotor deficits, among others. Hypo-sensitivity and hyper-sensitivity to different stimuli within the same sensory modality, a prominent symptom of ASD, can be assessed by acoustic startle response (ASR) and prepulse inhibition (PPI). Propionic acid (PPA) is a short-chain fatty acid and a by-product of the human gut microbiome.
