Taurine promotes glucagon‐like peptide‐1 secretion in enteroendocrine L cells
FEBS Letters, EarlyView.Taurine, a sulfur‐containing amino acid, is likely taken up by enteroendocrine L cells via the taurine transporter. This process increases the levels of cytosolic ATP. The increase in intracellular Ca2+ concentrations and glucagon‐like peptide‐1 secretion through membrane depolarization is caused by the closure of ATP‐sensitive potassium channels ...

Effect of Different Surface Treatments on the Repair of Aged Bulk-Fill Composites: An In Vitro Study
Cumhuriyet Dental Journal, 2019 Objectives: The aim of this in vitro study was to evaluate the efficiency of different surface treatments on the microtensile bond strength (µTBS) of aged bulk-fill composite.Materials and Methods: Sixty bulk-fill resin-based composite (RBC) specimens in

Wave transmission across surface interfaces in lattice structures [PDF]
, 2019 Within the lattice dynamics formulation, we present an exact solution for anti-plane surface waves in a square lattice strip with a surface row of material particles of two types separated by a linear interface. The considered problem is a discrete analog of an elastic half-space with surface stresses modelled through the simplified Gurtin-Murdoch ...

Making tau amyloid models in vitro: a crucial and underestimated challenge
FEBS Letters, EarlyView.This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

The Gauss map for Lagrangean and isoclinic surfaces [PDF]
arXiv, 2013 Simple properties of the Gauss map characterise important classes of surfaces in $\Rq$: $R$-surfaces, the real version of plane complex curves; Lagrangean surfaces; isoclinic surfaces.

FEBS Letters, EarlyView.α2 → 8 polysialic acid elicits poor immunogenicity. Small‐angle scattering shows a supramolecular structure with parallel‐chain binding, although in different forms at μm and mm calcium. The major histocompatibility complex requires molecular weights around 2000 Da to produce antibodies, and 2000 Da polysialic oligomers will bind in these structures ...

Bour's spacelike maximal and timelike minimal surfaces in the 3-dimensional Minkowski space [PDF]
arXiv, 2014 Bour's minimal surface has remarkable properties in three dimensional Minkowski space. We reveal the definite and indefinite cases of the Bour's surface using Weierstrass representations, and give some differential geometric properties of the astonishing maximal and minimal surfaces.
