Is RED-S in athletes just another face of malnutrition?

Clinical Nutrition ESPEN, 2022
Relative energy deficiency syndrome in sport (RED-S) can impair the function of several body systems, resulting in short and long-term threats to athletes' health and performance. Research showed that these health and performance problems are often unrecognized, and the treatment is not adequate.

Female Athlete Triad and RED-S

2019
The Female Athlete Triad and Relative Energy Deficiency in Sport are clinical syndromes that have evolved over the past two and half decades, relating energy availability to health and performance deficits in athletes. It has become evident that low energy availability predisposes athletes to possible physical injury, systemic pathology, psychological ...

Alizarin red-S complexes of organotin compounds

Journal of Inorganic and Nuclear Chemistry, 1965
Abstract The nature and composition of the complexes between alizarin red-S and the organotin compounds RSnX 3 and R 2 SnX 2 (R  CH 3 , C 6 H 5 ; X  Cl − , Br − , ClO 4 − ) have been studied spectrophotometrically in aqueous and in mixed water-ethanol solutions.

Kinetics of the alizarine red S surface redox reaction

Analytical and Bioanalytical Chemistry, 1996
Kinetics of the surface redox reaction of alizarine red S adsorbed on mercury is measured by square-wave voltammetry. In 1 mol/l KNO(3) buffered to pH 9.22, the standard reaction rate constant of the redox couple anthraquinone/anthrahydroquinone in the adsorbed alizarine red S molecule is k(s)=100 +/-10 s(-1) and the cathodic transfer coefficient is ...

Lanthanum-Alizarine Red S chelate

Microchemical Journal, 1965
Summary Formation of a pink-colored chelate between lanthanum and Alizarine Red S has been reported. The region of maximum absorbance of the chelate lies at 520 mµ . The molar ratio of lanthanum to the chelating agent has been determined to be 1:2, using three different methods: the mole ratio method, the slope ratio method, and the method of ...

Staining properties of alizarin red S for growing bone in vitro

Cells Tissues Organs, 1980
The pH-metric titration curve of alizarin red S (ARS) showed that ARS ionizes in three stages: firstly the –SO₃Na group, secondly the β-hydroxyl group, and finally on the alkaline side the α-hydroxyl group. The titration of ARS solution with calcium ions indicates that complex and chelate formation between ARS and calcium are ...

Alizarin Red S as an electrochemical indicator for saccharide recognition

Electrochimica Acta, 2011
Abstract In addition to the well-established spectroscopic Alizarin Red S (ARS) assay for the determination of binding constants between arylboronic acids and different saccharides, we report the use of ARS as a reporter in an electrochemical set-up.

Relative Energy Deficiency in Sports (RED-S)

Deutsche Zeitschrift für Sportmedizin
This overview intends to show a possible diagnostic/treatment pathway for athletes with an energy deficiency. This is based on the IOC statement paper (13), which was recently revised in 2023. An interdisciplinary approach is important to reach all aspects.

Spectrophotometric study of the complex of lanthanum and alizarin Red S

Talanta, 1961
Abstract The complex of lanthanum with alizarin Red S in acetate medium has been studied spectrophotometrically since it appears to be promising for the determination of the chemical yield in radioactivation analysis of rare earth elements. At pH 4.6 (acetate buffer) the molecular ratio lanthanum: alizarin Red S is 1:2.
