Influence of androgen receptor on bone health in transgender adults: insights from the COMET study.

Purpose: Previous studies show that transgender and gender-diverse (TGD) individuals, especially those assigned male at birth (AMAB), often have low bone mineral density (BMD) before beginning gender-affirming hormone therapy (GAHT). The reasons for this are not fully understood, and the potential role of androgen receptor (AR) polymorphisms - known to affect bone density in the general population - has not been explored. This study aims to assess the impact of AR polymorphisms on bone health in the TGD population.

A high-efficient electrochemical degradation of diclofenac in water on planar and microstructured 2D, and macroporous 3D boron-doped diamond electrodes: Identification of degradation and transformation products.

The highly efficient degradation of persistent organic substances by electrochemical advanced oxidation processes (EAOPs), which don't result in the formation of potentially harmful by-products, is crucial for the future of water management. In this study, boron-doped diamond electrodes (BDDE) with three morphologies (planar 2D, microstructured 2D, and macroporous 3D) were employed for the anodic oxidation of diclofenac (DCF) in two working electrolytes (NaCl and NaSO). In total, 11 by-products formed during the electrochemical oxidation of DCF were identified via HPLC-HRMS.

Nanostructured Boron-Doped Ultra-Nanocrystalline Diamond Micro-Pyramids: Efficient Electrochemical Supercapacitors.

The miniaturization of electrochemical supercapacitors (EC-SCs) requires electrode materials that are both durable and efficient. Boron-doped diamond (BDD) films are an ideal choice for EC-SC due to their durability and exceptional electrochemical performance. In this study, nanostructured boron-doped ultra-nanocrystalline diamonds (NBUNCD) are fabricated on Si micro-pyramids (Si) using a simple reactive ion etching (RIE) process.

Determination of melatonin by potentiometric stripping analysis using sensor based on boron-doped diamond electrodes.

A three-electrode screen-printed sensor with heavily doped microcrystalline boron-doped diamond electrodes grown by chemical vapor deposition on alumina substrates was used to determine the concentration of melatonin by constant current potentiometric stripping analysis. This paper provides a detailed examination of the irreversible oxidation behavior of melatonin by cyclic voltammetry at a boron-doped diamond electrode. The relationship between the current response and the square root of the scan rate confirmed a diffusion-controlled oxidation process.

Sensitive and eco-friendly voltammetric detection of galantamine using a screen-printed sensor with a functional boron-doped diamond electrode.

The presented study focused on developing and optimizing a modern electroanalytical platform for the direct quantitative determination of galantamine. This work used different voltammetric methods to use a screen-printed sensor with a working boron-doped diamond electrode (SP/BDDE). Beneficial analytical performance for detecting galantamine was achieved in a Britton-Robinson buffer with pH 3.
