BACKGROUND AND PURPOSE: A population-based Copenhagen birth year 1948 cohort with high myopia recorded since age 14 years (spherical equivalent less than or equivalent to -6 D) has been followed over 50 years. Despite complications, current follow-ups have outlined a better visual prognosis than usually drawn from selected clinical series in the literature. For the present status at age 66 years, focus was on visual ability and choroidal thickness. METHODS: Twenty-eight of the original 39 participants were available in 2014...

Associating polymers are a class of materials with widely tunable macroscopic properties. Here, we investigate telechelic poly(dimethylsiloxanes) of several molecular weights (MW) with different hydrogen bonding end groups. Besides the well-established increase of the glass transition temperature Tg with decreasing MW, Tg remains unchanged as the end group varies from NH2 over OH to COOH. For the latter system, a 2nd Tg is found which indicates a segregated phase. In contrast, rheological measurements reveal a qualitative difference in the viscoelastic response of NH2-terminated and COOH-terminated chains...

Cardiovascular diseases (CVDs) are arguably the most important comorbidities in chronic obstructive pulmonary disease (COPD). CVDs are common in people with COPD, and their presence is associated with increased risk for hospitalization, longer length of stay and all-cause and CVD-related mortality. The economic burden associated with CVD in this population is considerable and the cumulative cost of treating comorbidities may even exceed that of treating COPD itself. Our understanding of the biological mechanisms that link COPD and various forms of CVD has improved significantly over the past decade...

Compressed sensing (CS) reconstructions of under-sampled measurements generate missing data based on assumptions of image sparsity. Non-contrast time-of-flight MR angiography (TOF-MRA) is a good candidate for CS based acceleration, as MRA images feature bright trees of sparse vessels over a well-suppressed anatomical background signal. A short scan time derived from CS is beneficial for patients of moyamoya disease (MMD) because of the frequency of MR scans. The purpose of this study was to investigate the reliability of TOF-MRA with CS in the evaluation of MMD...

Sean Noah, Cynthia Gibson-Horn, Jennifer L Vincenzo
BACKGROUND AND PURPOSE: The Centers for Disease Control and Prevention estimated that there were 29 million falls and 7 million injuries in 2014 in the United States. Falls, decreased balance, and mobility disability are common in older adults and often result in loss of independence. Finding interventions to address these issues is important, as this age group is growing exponentially. Prior studies indicate balance and mobility can be improved by the balance-based torso-weighting (BBTW) assessment implemented through wear of a balance orthotic (BO)...

Squamous cell carcinoma of the head and neck, SCCHN, is a heterogeneous group of tumours not only concerning site of origin but also regarding aetiology. The 5-year survival for the whole group of SCCHN tumours has not significantly improved over the last 20-25 years. Apart from tumour spread to lymph nodes, N status, gains and losses of specific chromosomes are the only factors shown to be independent prognostic markers for these tumours. Worldwide an increasing number of people ? 40 years are seen being affected by tongue SCC, the most common tumour within the SCCHN group...
