Abstract Study question Can supplementation with additional rectal administration of progesterone secure high ongoing pregnancy rates (OPR) in patients low serum (P4) at blastocyst transfer (ET)? Summary answer Rectally administered starting on the day secures OPR P4 levels lower than 35 nmol/l (11ng/ml). What is known already Low peri-implantation HRT-FET cycles impact reproductive outcomes ne...

We present a simple and robust isotachophoresis (ITP) method that can be integrated with microchip-based capillary electrophoresis (CE) devices to achieve millionfold sample stacking. We performed an experimental parametric study to show the effects of initial sample ion concentration, leading ion concentration, and trailing ion concentration on ITP stacking. We also discuss the usefulness and ...

We have discovered that the immunoreactivity of the fluorophore Alexa Fluor 488 survives glutaraldehyde and osmium tetroxide fixation and epoxy resin embedding and etching. We have developed new localization methods that for the first time take advantage of this property. The antigen is localized in cryosections using suitable primary antibody and an Alexa Fluor 488-conjugated secondary antibod...

(2S,3S,4S,5R,6R)-6-(4-((4-guanidinobutoxy)carbonyl)-2,6-dihydroxyphenoxy)-3,4,5-trihydroxytetrahydro-2H-pyran-2-carboxylic acid (ZYZ-488) was discovered as a novel inhibitor of apoptotic protease activating factor-1 (Apaf-1). In present work, a surface plasmon resonance (SPR) assay confirms the direct binding between ZYZ-488 and Apaf-1 and this interaction was found to be able to block the recr...

We report the observation of planar Y-junction waveguide splitters that are due to the bulk photovoltaic effect. The junctions are generated by multiple dark-soliton propagation in LiNbO(3) by use of low power levels (20 mW) and average intensities of 10 W/cm(2) at 488 nm. The junctions persist in the dark and can be used to divide input beams of less photorefractive sensitivity. We describe so...

Lasers are the principle light sources of flow cytometers. Most modern benchtop instruments feature air-cooled argon-ion laser emitting 10-25 mW of light at 488 nm. This unit covers the various types of lasers available and the qualities that make them suitable or unsuitable for use in flow cytometers. Also included is a discussion of future directions, particularly in the development of solid-...
