In platelet single donor apheresis, platelet factor 4 levels correlated with donor's age and decreased during storage.

The human population is ageing worldwide. The World Health Organization estimated that the world's population of people aged 60 years and older will increase to at least 30%, coinciding with a growing frequency of cognitive and cardiovascular disease. Recently, in preclinical studies platelet Factor 4 (PF4) was presented as a pro-cognitive factor.

Dataset of ocean vessel traffic in the North Sea.

Automatic Identification System (AIS) is a technology that allows ships to broadcast their position, course, speed, and other information to other vessels or shore-based stations. By collecting and analysing this data, it is possible to create a heatmap of ship activity in a particular region, such as the North Sea. This heatmap acts as a representation of vessel activity per class.

Keratoconus in Inflammatory Bowel Disease Patients: A Cross-sectional Study.

Background And Aims: Increasing evidence suggests that keratoconus may have an inflammatory component. The possible association of keratoconus with inflammatory bowel disease (IBD) has yet to be determined. The aim of this study was to determine the prevalence of keratoconus and suspect keratoconus in patients with IBD.

Fano profiles in two-photon photoassociation spectra.

In this article we derive the lineshapes observed in two-photon photoassociation spectrocopy of molecules using an effective Hamiltonian adapted from previous work in atomic physics. The lineshape is decomposed in terms of sums and products of Breit-Wigner and Fano profiles, which we associate with physical absorption and emission processes, and to quantum interferences between transition amplitudes. We emphasize the specific features which do not exist in the atomic case, linked to the dissociation width of the photoassociated molecules in the electronic ground state.

Accurate determination of the scattering length of metastable helium atoms using dark resonances between atoms and exotic molecules.

We present a new measurement of the s-wave scattering length a of spin-polarized helium atoms in the 2(3)S1 metastable state. Using two-photon photoassociation spectroscopy and dark resonances, we measure the energy E(nu)=14= -91.35+/- 0.
