Under-recognised neurocognitive deficits in adults and adolescents with tuberous sclerosis complex.

Background: Tuberous sclerosis complex (TSC) is a genetic disease characterised by the growth of benign tumours. The Tuberous sclerosis Associated Neuropsychiatric Disorders (TAND) Checklist is used to identify patient-reported neurocognitive deficits. Patients may, however, under-recognise mild cognitive impairment.

Clinical Reasoning: A 3-Year-Old Boy With Abnormal Movements During Sleep.

We report a case of a 3-year-old boy who presented with abnormal movements that initially occurred only during sleep. Three years later, he went on to develop hyperkinetic movements during the daytime while awake. There was a strong family history of various paroxysmal neurologic disorders.

Interactions between dietary fat intake and FASN genetic variation influence LDL peak particle diameter.

Background: The small, dense LDL phenotype is associated with an increased cardiovascular disease risk. A genome-wide scan performed on the Quebec Family Study (QFS) revealed a quantitative trait locus for LDL peak particle diameter (LDL-PPD) on the 17q21 region. A positional candidate gene - the fatty acid synthase gene (FASN) - encodes a key enzyme in the biogenesis of membrane lipids.

High-throughput screening for mTORC1/mTORC2 kinase inhibitors using a chemiluminescence-based ELISA assay.

A high-throughput chemiluminescence and ELISA-based biochemical assay to identify mTORC1/mTORC2 kinase inhibitors is described. These mTOR complexes were isolated from HeLa whole cell lysate using mTOR antibodies and in-well immunoprecipitation. The integrity and purity of the mTORC1 and mTORC2 immunocomplexes were confirmed by western blotting.
