Job precarity impacts the mental health of contractual teachers in Morocco: between fatigue and psychological distress.

Introduction: since the Ministry of National Education introduced contractual recruitment in 2016, Morocco has faced significant challenges related to the well-being of its contractual teachers. This study investigates the impact of job precarity on the mental health of these teachers, specifically focusing on fatigue and psychological distress.

Methods: we collected responses from 245 contractual teachers across Morocco's 12 regions, utilizing the Individual Strength Checklist (CIS) to assess fatigue and the General Health Questionnaire (GHQ) for psychological distress.

A unique hydrophobic domain of rat brain globular acetylcholinesterase for binding to cell membranes.

Both salt-soluble and detergent-soluble rat brain globular acetylcholinesterases (SS- and DS- AChE EC 3.1.1.

Separation in a single step by affinity chromatography of cholinesterases differing in subunit number.

We describe an affinity chromatography method in which dimethylaminoethylbenzoic acid-Sepharose 4B is used, making it possible to separate in one step the molecular forms of globular acetylcholinesterase (AChE, EC 3.1.1.

Are soluble and membrane-bound rat brain acetylcholinesterase different?

Salt-soluble and detergent-soluble acetylcholinesterases (AChE) from adult rat brain were purified to homogeneity and studied with the aim to establish the differences existing between these two forms. It was found that the enzymatic activities of the purified salt-soluble AChE as well as the detergent-soluble AChE were dependent on the Triton X-100 concentration. Moreover, the interaction of salt-soluble AChE with liposomes suggests amphiphilic behaviour of this enzyme.
