Androgen increases klotho expression via the androgen receptor-mediated pathway to induce GCs apoptosis

Journal of Ovarian Research, 2023
Background Many epidemiological studies have shown that anovulatory polycystic ovary syndrome (PCOS) is accompanied by hyperandrogenism. However, the exact mechanism of hyperandrogen-induced anovulation remains to be elucidated.

On the stability of Murray's testosterone model [PDF]

arXiv, 2004
We prove the global asymptotic stability of a well-known delayed negative-feedback model of testosterone dynamics, which has been proposed as a model of oscillatory behavior. We establish stability (and hence the impossibility of oscillations) even in the presence of delays of arbitrary length.

Guidelines for the standardization of pre‐analytical variables for salivary biomarker studies in Alzheimer's disease research: An updated review and consensus of the Salivary Biomarkers for Dementia Research Working Group

Alzheimer's &Dementia, Volume 21, Issue 2, February 2025.
Abstract There is a pressing need for accessible biomarkers with high diagnostic accuracy for Alzheimer's disease (AD) diagnosis to facilitate widespread screening, particularly in underserved groups. Saliva is an emerging specimen for measuring AD biomarkers, with distinct contexts of use that could complement blood and cerebrospinal fluid and detect ...

Local and global analysis of endocrine regulation as a non-cyclic feedback system [PDF]

, 2016
To understand the sophisticated control mechanisms of the human's endocrine system is a challenging task that is a crucial step towards precise medical treatment of many disfunctions and diseases. Although mathematical models describing the endocrine system as a whole are still elusive, recently some substantial progress has been made in analyzing ...
