Brain maps of general cognitive function and spatial correlations with neurobiological cortical profiles.

In this paper, we attempt to answer two questions: 1) which regions of the human brain, in terms of morphometry, are most strongly related to individual differences in domain-general cognitive functioning ( )? and 2) what are the underlying neurobiological properties of those regions? We meta-analyse vertex-wise -cortical morphometry (volume, surface area, thickness, curvature and sulcal depth) associations using data from 3 cohorts: the UK Biobank (UKB), Generation Scotland (GenScot), and the Lothian Birth Cohort 1936 (LBC1936), with the meta-analytic = 38,379 (age range = 44 to 84 years old). These morphometry associations vary in magnitude and direction across the cortex (|β| range = -0.12 to 0.

Systematic review: differences in complete blood count component rhythms.

Study Objectives: The complete blood count (CBC) is one of the most commonly ordered blood tests with a large range of reference values that does not consider time of day for interpretation. Our objective was to systematically review this topic to report on peak and trough timing of CBC values.

Methods: A systematic search was performed for studies evaluating any component of the CBC with at least three collections over 24 hours.

Production of Pectic Oligosaccharides from Citrus Peel via Steam Explosion.

Steam explosion (STEX) of peel from commercially juice-extracted oranges was used to convert peel pectin into pectic oligosaccharides (POSs). Surprisingly uniform populations, based on the polydispersity index (PDI; weight-average molecular weight (M)/number-average molecular weight (M)) of POSs, were obtained from the Hamlin and Valencia varieties of . The POSs from Hamlin and Valencia peel had PDI values of (1.

Airway total bacterial density, microbiota community composition and relationship with clinical parameters in bronchiectasis.

Background And Objective: This study explored the relationship between total bacterial density, airway microbiota composition and clinical parameters in bronchiectasis. We determined changes with time during clinical stability and following antibiotic treatment of a pulmonary exacerbation.

Methods: We conducted a multicentre longitudinal cohort study of UK participants with CT confirmed bronchiectasis.

Lifetime brain atrophy estimated from a single MRI: measurement characteristics and genome-wide correlates.

A measure of lifetime brain atrophy (LBA) obtained from a single magnetic resonance imaging (MRI) scan could be an attractive candidate to boost statistical power in uncovering novel genetic signals and mechanisms of neurodegeneration. We analysed data from five young and old adult cohorts (MRi-Share, Human Connectome Project, UK Biobank, Generation Scotland Subsample, and Lothian Birth Cohort 1936 [LBC1936]) to test the validity and utility of LBA inferred from cross-sectional MRI data, i.e.
