Article Abstract
An innovative, simple and cost effective Tb-atorvastatin photo probe was designed and used as a core for a spectrofluorometric approach to sensitively determine two vital biological compounds in serum samples. Tb-atorvastatin complex displays a characteristic electrical band with at 545 nm with significant luminescence intensity, which is quenched in the presence of progesterone and testosterone at two variant sets of pH; 6.2 and 7.5, respectively. The conditions were optimized and the best solvent for operation was found to be acetonitrile with at 320 nm. Progesterone and testosterone were assessed in serum samples using the same optimal conditions within concentration ranges of 2 × 10 to 2.9 × 10 and 3.1 × 10 to 4.8 × 10 mol L, respectively. The proposed luminescence method was validated in accordance to ICH guidelines and found to be accurate, precise and specific and free from any interference. The cost effectiveness and applicability of the method make it a good choice for routine analysis of the two compounds and early diagnosis of chronic diseases associated with abnormalities in their physiological levels.

Overreaching, a consequence of intensified training, is used by athletes to enhance performance. A blunted hormonal response to a 30-min interval exercise stress test (55/80) has been shown in males after intensified training, highlighting cortisol and testosterone as potential biomarkers of overreaching. Despite accounting for ~50% of the population, studies into hormonal responses to exercise in females are lacking.

Atrazine is an herbicide widely used on plantations worldwide. Experimental studies suggest that the herbicide impairs male reproductive function in mammals. This systematic review and meta-analysis aimed to evaluate the impact of atrazine exposure on the levels of hormones from the hypothalamic-pituitary-testicular axis using murine as the animal model.

The global decline of species necessitates intensive conservation efforts, including ex-situ breeding programs to safeguard endangered populations. However, managing welfare and reproduction in zoological gardens can present several challenges. This study aims to explore behaviors and endocrinological responses of two specimens of fossa (Cryptoprocta ferox) under human care.

Saliva samples offer the possibility to obtain stress-free non-invasive samples, also for home-testing, especially useful when blood collection is either undesirable or difficult. The aim of this work was to develop an LC-MS/MS method to determine clinically relevant steroid hormones cortisol, cortisone, 11-deoxycortisol, 21-deoxycortisol, 17OH-progesterone, aldosterone, corticosterone, deoxycorticosterone, testosterone, androstenedione, DHEAS, DHEA, 17OH-pregnenolone, betamethasone and dexamethasone. A special effort was made to adapt the method to neonatal population with respect to choice of saliva as matrix, low sample volumes, selection of analytes and multiplexing.

It is well known that the function of granulosa cells (GCs) is closely related to follicular development, and and histone methylation have been implicated in follicular development. However, the specific mechanisms by which and histone methylation regulate follicular development are still largely unknown. To explore the specific mechanism of in regulating follicular development, in this study, we showed that the expression of in immature ovaries and small follicles was significantly higher than in mature ovaries and large follicles of sows, respectively.
