Castration modulates singing patterns and electrophysiological properties of RA projection neurons in adult male zebra finches [PDF]

open access: yesPeerJ, 2014
Castration can change levels of plasma testosterone. Androgens such as testosterone play an important role in stabilizing birdsong. The robust nucleus of the arcopallium (RA) is an important premotor nucleus critical for singing.

A Comparison of a Novel Testosterone Bioadhesive Buccal System, Striant, with a Testosterone Adhesive Patch in Hypogonadal Males [PDF]

open access: yesThe Journal of Clinical Endocrinology & Metabolism, 2004
A novel delivery system has been developed for testosterone replacement. This formulation, COL-1621 (Striant), a testosterone-containing buccal mucoadhesive system, has been shown in preliminary studies to replace testosterone at physiological levels when used twice daily.

Indomethacin Abolishes the Potentiation Effect of Testosterone on the Relaxation Induced by Salbutamol and Theophylline by Directly Blocking the K+ Channels in Airway Smooth Muscle [PDF]

open access: yesMolecules
Indomethacin, ibuprofen, and acetylsalicylic acid (ASA) are non-steroidal anti-inflammatory drugs (NSAIDs) that inhibit prostaglandin (PG) synthesis. Previous studies in airway smooth muscle demonstrated that chronic exposure to testosterone (TES, 40 nM)

The unsolved case of “bone-impairing analgesics”. The endocrine effects of opioids on bone metabolism [PDF]

open access: yesThe Journal of Pain, 2015
The current literature describes the possible risks for bone fracture in chronic analgesics users. There are three main hypotheses that could explain the increased risk of fracture associated with central analgesics, such as opioids: 1) the increased ...

Testosterone and the dark ventral patch of male red deer: the role of the social environment

open access: yesThe Science of Nature, 2020
The expression of male sexual traits, which is stimulated by testosterone, entails significant costs for individuals. Consequently, natural selection is expected to favour the modulation of sexual trait development according to the balance between its costs and benefits.

Estradiol decreases the excitability of RA projection neurons in adult male zebra finches

open access: yesFrontiers in Cellular Neuroscience, 2023
Zebra finches are essential animal models for studying learned vocal signals. The robust nucleus of the arcopallium (RA) plays an important role in regulating singing behavior.

Testosterone-Induced Expression of Male Colour Morphs in Females of the Polymorphic Tawny Dragon Lizard, Ctenophorus decresii. [PDF]

open access: yesPLoS ONE, 2015
Many colour polymorphisms are present only in one sex, usually males, but proximate mechanisms controlling the expression of sex-limited colour polymorphisms have received little attention.
