A study of CIS-acting elements required for dosage compensation in Drosophila Melanogaster : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Genetics at Massey University, Palmerston North, New Zealand [PDF]

, 2000
Dosage compensation (the equalisation of X-linked gene products) occurs in Drosophila melanogaster by a two fold transcriptional up-regulation of X-linked gene expression in males. This involves the binding of five proteins, MSL-1, MSL-2, MSL-3, MLE, MOF,

Characterization of atrazine-induced gonadal malformations in African clawed frogs (Xenopus laevis) and comparisons with effects of an androgen antagonist (cyproterone acetate) and exogenous estrogen (17beta-estradiol): Support for the demasculinization/feminization hypothesis. [PDF]

, 2006
Atrazine is a potent endocrine disruptor that both chemically castrates and feminizes male amphibians. It depletes androgens in adult frogs and reduces androgen-dependent growth of the larynx in developing male larvae.

Myofibrillar fragmentation in entire male, immunocastrated or surgically castrated pigs

IOP Conference Series: Earth and Environmental Science, 2019
Abstract In order to better characterise differences in meat quality traits between the alternatives to surgical castration, myofibrillar fragment length was investigated in longissimus dorsi muscle of entire (n=12), immunocastrated (n=12) and surgically castrated (n=12) male pigs. Higher myofibrillar fragment length was observed in meat

Accessory sex glands as a tool to measure the efficacy of immunocastration in male pigs

Animal, 2010
The use of an anti-gonadotropin-releasing hormone vaccine for immunocastration of male pigs has been recently approved in the European Union. This technique is potentially useful for avoiding both castration-associated pain for the animal and boar taint ...
