Background: The Montreal Cognitive assessment (MoCA) is a well-validated global cognitive screening instrument. Its validity in progressive supranuclear palsy (PSP) has not been assessed.

Objectives: To evaluate the MoCA as an outcome measure in PSP clinical trials.

Background: Standardised Diagnostic Assessment tools, such as the Development and Well-Being Assessment (DAWBA), may aid detection and diagnosis of emotional disorders but there is limited real-world evidence of their clinical or cost effectiveness.

Methods: We conducted a multicentre, two-arm parallel group randomised controlled trial in eight large National Health Service Trusts in England providing multidisciplinary specialist Child and Adolescent Mental Health Services (CAMHS). Participants (5-17 year-olds with emotional difficulties referred to CAMHS) were randomly assigned (1:1), following referral receipt, to either receive the DAWBA and assessment-as-usual (intervention group) or assessment-as-usual (control group).

Bone fracture repair initiates by periosteal expansion. The periosteum is typically quiescent, but upon fracture, periosteal cells proliferate and contribute to bone fracture repair. The expansion of the periosteum is regulated by gene transcription; however, the molecular mechanisms behind periosteal expansion are unclear.

The present study reveals an unexpected anomaly observed in the acid-catalyzed hydrolysis of the 5,6-O-isopropylidene group in 3-O-protected D-gluco- and D-allofuranose derivatives. Although the removal of the 5,6-O-isopropylidene protecting group is typically rapid and quantitative under acidic conditions, an unexpected inhibition of this reaction is observed for the two C3-epimers, 3-O-imidazole sulfonyl moiety. X-ray data show a two-faced imidazole ring orientation in the crystal, while solution state NOE data reveal a critical interaction type between the isopropylidene and the imidazole rings.
