Implementing and evaluating far-field 3D X-ray diffraction at the I12 JEEP beamline, Diamond Light Source.

Three-dimensional X-ray diffraction (3DXRD) is shown to be feasible at the I12 Joint Engineering, Environmental and Processing (JEEP) beamline of Diamond Light Source. As a demonstration, a microstructually simple low-carbon ferritic steel was studied in a highly textured and annealed state. A processing pipeline suited to this beamline was created, using software already established in the 3DXRD user community, enabling grain centre-of-mass positions, orientations and strain tensor elements to be determined.

Long-acting, reversible and permanent methods of contraception: insight into women's choice of method.

Background: This study aims to explore the views of women concerning their choice of long-acting method of contraception.

Method: Two-hundred and eighty-six women who had either been sterilised or fitted with an etonorgestrel (ETN) implant or the levonorgestrel intrauterine system (LNG IUS) were invited to take part. A response rate of 54% was achieved.

Reactive oxygen species limit neutrophil life span by activating death receptor signaling.

Neutrophils are abundant, short-lived leukocytes, and their death by apoptosis is central to hemostasis and the resolution of inflammation, yet the trigger for their entry into apoptosis is unknown. We show here that death receptor signaling, including CD95 death-inducing signaling complex (DISC) formation and caspase 8 activation, occurred early in neutrophil apoptosis. However, death receptor ligation was not required for apoptosis, suggesting a novel mechanism for caspase 8 activation.
