Application of DFTB and machine learning to evaluate the stability of biomass intermediates on the Rh(111) surface [PDF]

arXiv, 2021
Biomass compounds adsorbed on surfaces are challenging to study due to the large number of possible species and adsorption geometries. In this work, possible intermediates of erythrose, glyceraldehyde, glycerol and propionic acid are studied on the Rh(111) surface.

Some solute-solvent complexes involving testosterone and testosterone propionate

Journal of Pharmacy and Pharmacology, 1981
Abstract Solute-solvent interactions have been studied by observing the influences of carbon tetrachloride, carbon disulphide, ethyl oleate, isopropyl myristate and octanol on the solubilities of testosterone and testosterone propionate in an inert solvent (cyclohexane).

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 ...

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.

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.

Update vulval dermatology – diagnostics and therapy

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, Volume 23, Issue 1, Page 65-86, January 2025.
Summary The vulva is a periorificial skin area and as such represents a transitional zone with unique functional and physiological characteristics. Knowledge of its anatomy is limited among both the general population and healthcare professionals, and unrealistic expectations of normal proportions are common.

Action spectroscopy of gas-phase carboxylate anions by multiple photon IR electron detachment/attachment [PDF]

, 2008
We report on a form of gas-phase anion action spectroscopy based on infrared multiple photon electron detachment and subsequent capture of the free electrons by a neutral electron scavenger in a Fourier Transform Ion Cyclotron Resonance (FTICR) mass spectrometer.

Morphological changes induced by testosterone in the mammary glands of female Wistar rats

Brazilian Journal of Medical and Biological Research, 2005
Increased levels of androgens in postmenopausal women are considered to be a risk factor for breast cancer. Testosterone, alone or in combination with estrogen, induces epithelial dysplasia and mammary tumors in Noble rats.
