Enhanced HPLC Method for Boar Taint Quantification [PDF]

ChemistryOpen
Boar taint is an unpleasant odour found in the carcasses of entire male pigs, resulting from androstenone and skatole accumulation during pubertal development, and impacting pork quality.

Hepatic Gene Expression and Metabolite Profiles of Androstenone and Skatole Relative to Plasma Estrone Sulfate Levels in Boars [PDF]

Biomolecules
Testicular steroids can alter the activity and expression of enzymes within the liver and may influence the metabolism of skatole and androstenone, which are responsible for boar taint.

Inter-laboratory comparison of methods to measure androstenone in pork fat

Animal, 2011
Today, different analytical methods are used by different laboratories to quantify androstenone in fat tissue. This study shows the comparison of methods used routinely in different laboratories for androstenone quantification: Time-resolved ...

INSL3 Expression in Leydig Cells is a Biomarker for Immunocastration in Boars: Transcriptional Evidence. [PDF]

Andrology
ABSTRACT Background Study aimed to obtain insights into physiological responses to immunocastration in pubertal boars by evaluating effects of alternative vaccination protocols and identifying a reliable immunocastration biomarker. Objectives It was hypothesized that the timing of gonadotropin‐releasing hormone (GnRH) suppression by immunocastration ...

Antimelanoma activities of chimeric thiazole–androstenone derivatives [PDF]

Royal Society Open Science, 2021
The discovery of chimeric anti-melanoma agents is reported. These molecules are potent growth suppressors of melanoma cells in vitro with growth inhibition of 50% (GI 50 ) values as low as 1.32 µM. Compounds were more toxic to melanoma cells in vitro than commonly used

The Effects of Androstenone on the Plasma Serotonin, β-Endorphin, and Cortisol Concentrations in Thoroughbred Horses

Animals, 2021
Androstenone influences the changing behaviors of animals. Previous studies discovered that an androstenone receptor was expressed in horses and treatment with androstenone induced horses to be more compliant.

Genetic variation of an odorant receptor OR7D4 and sensory perception of cooked meat containing androstenone. [PDF]

PLoS ONE, 2012
Although odour perception impacts food preferences, the effect of genotypic variation of odorant receptors (ORs) on the sensory perception of food is unclear.

The Prevalence of Androstenone Anosmia [PDF]

Chemical Senses, 2003
It has been estimated that approximately 30% of the population is unable to detect the odor of androstenone. These estimates, however, were made using tests and criteria optimized for identifying detection. Such criteria favor Type II over Type I errors--that is, they are excellent at identifying true detectors at the cost of erroneously labeling some ...

Political attitudes vary with detection of androstenone [PDF]

Politics and the Life Sciences, 2020
AbstractBuilding on a growing body of research suggesting that political attitudes are part of broader individual and biological orientations, we test whether the detection of the hormone androstenone is predictive of political attitudes. The particular social chemical analyzed in this study is androstenone, a nonandrogenic steroid found in the sweat ...

Optimizing Odorants for Olfactory Training Based on Olfactory Receptor-Ligand Pair Analysis. [PDF]

Laryngoscope
This study employs receptor–ligand interaction analysis and olfactory epithelium transcriptomics to optimize olfactory training (OT). A novel four‐odorant combination (galaxolide, eugenol acetate, [−]‐menthol, geranyl acetate) activates 83.9% of 385 human olfactory receptors (ORs), covering 69.9% of estimated OR expression—significantly outperforming ...
