Context: The goal of this review is to move beyond summarizing what is known about psychosexual development in females with classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency-commonly studied as a natural experiment to understand prenatal androgen effects in 46,XX individuals. Instead, it will explore the various aspects of the condition that significantly impact the daily lives of both male and female patients and their families, with a particular focus on the implications for psychosocial, educational, and vocational adaptation.
Evidence Acquisition: This work represents a selective, yet balanced review of papers highlighting potential threats to positive psychological adaptation in both male and female individuals with CAH.
Tannins are critical plant defense metabolites, enriched in bark and leaves, that protect against microorganisms and insects by binding to and precipitating proteins. Hydrolyzable tannins contain ester bonds which can be cleaved by tannases-serine hydrolases containing so-called "cap" domains covering their active sites. However, comprehensive insights into the biochemical properties and structural diversity of tannases are limited, especially regarding their cap domains.

However, the chemical reaction between wood and the modification reagents has not been studied yet. To resolve this, the reaction was studied with solid-state C cross-polarization magic-angle-spinning (CP-MAS) and P MAS nuclear magnetic resonance (NMR) and X-ray photoelectron spectroscopy (XPS) to reveal the formation of bonds between wood components, MA and SHP during the treatments to explain the formation of cross-linking and the possible fixation of phosphorus in wood.
