Native mass spectrometry allows the screening of possible protein bioreceptors for perfluorinated alkyl substances.

Screening for impaired distant visual acuity was one component of a controlled trial of multiphasic screening in middle age carried out in two general practices. The prevalence of impaired visual acuity (6/18 or worse in the better eye) at the initial screening in 1967 was 9.6% overall, ranging from 5.9% in people aged 40-49 years to 16.3% in those aged over 60. The question "Do you have diffic...

BACKGROUND Celiac disease (CD) is common and, when undiagnosed, may result in increased mortality, suggesting that mass screening could be justified. The authors examined the cost-effectiveness (CE) of such an approach, assuming a higher mortality rate in undiagnosed CD and that adhering to a gluten-free diet (GFD) reduces the mortality rate. METHODS The authors developed a state transition M...

We investigate the finite-temperature excitation spectrum in the gluon sector of SU(3) pure gauge theory through measurements of screening masses in correlations of loop operators. We develop the classification of such operators under the symmetry group of the ‘z-slice’. In the confined phase of the theory, we find that the spectrum dynamically realises the zero temperature symmetries. We obser...
