The molecular structure of β-alanine is resistant to sterilising doses of gamma radiation.

β-alanine is the rate-limiting point for the endogenous synthesis of carnosine in skeletal muscle. Carnosine has a wide range of implications for health, normal function and exercise performance. Whilst the physiological relevance of carnosine to different tissues remains enigmatic, β-alanine administration is a useful strategy to investigate the physiological roles of carnosine in humans.

24-Week β-alanine ingestion does not affect muscle taurine or clinical blood parameters in healthy males.

Purpose: To investigate the effects of chronic beta-alanine (BA) supplementation on muscle taurine content, blood clinical markers and sensory side-effects.

Methods: Twenty-five healthy male participants (age 27 ± 4 years, height 1.75 ± 0.

High-Intensity Interval Training Augments Muscle Carnosine in the Absence of Dietary Beta-alanine Intake.

Purpose: Cross-sectional studies suggest that training can increase muscle carnosine (MCarn), although longitudinal studies have failed to confirm this. A lack of control for dietary β-alanine intake or muscle fiber type shifting may have hampered their conclusions. The purpose of the present study was to investigate the effects of high-intensity interval training (HIIT) on MCarn.

Endocrine disruption effects of p,p'-DDE on juvenile zebrafish.

The persistent organic pollutant p,p'-DDE, the major metabolite of the insecticide DDT, has displayed evidence of endocrine disruption through the inhibition of androgen binding to androgen receptors in different species. Although p,p'-DDE was continuously detected in wild fish with abnormal gonad development such as intersex, little is known about its mode of action during gonad development in fish. To elucidate the potential endocrine effects of this pollutant in zebrafish (Danio rerio), juveniles (30 days post hatch) were exposed to p,p'-DDE during the critical window of sexual differentiation.
