Measurement of lipid hydroperoxides by the ferric-xylenol orange method (1) characteristics of the ferric-xylenol orange/membrane phosphatidylcholine complex.

Kenji Fukuzawa et al.

Journal of nutritional science and vitaminology, 55(1), 9-14 (2009-04-09)

The ferric-xylenol orange (FOX) method for measurement of hydroperoxides is based on a technique that employs reduction of peroxides in an acidic condition by Fe2+ and formation of the colored ferric-xylenol orange (XO/Fe3+) product with a peak at 560 nm.

Healing of acute alveolar bone dehiscence following treatment with porous biphasic calcium phosphate in beagle dogs.

Lanlei Wang et al.

Clinical oral investigations, 15(6), 983-991 (2010-08-11)

The purpose of the present study was to evaluate histologically in beagle dogs the healing in acute dehiscence type defects following treatment with open flap debridement (OFD) with or without porous biphasic calcium phosphate (PBCP). Alveolar bone dehiscence defects were

A biodegradable scaffold for the treatment of a diaphyseal bone defect of the tibia.

Paul R T Kuzyk et al.

Journal of orthopaedic research : official publication of the Orthopaedic Research Society, 28(4), 474-480 (2009-10-28)

The aim of this study was to compare angiogenesis and osteogenesis occurring within 8.0 mm diaphyseal defects created in canine tibiae treated using autograft or a biodegradable bone scaffold. All tibiae were reamed to 7.0 mm and fixed with a

Analysis of lanthanide-induced conformational change of the C-terminal domain on centrin.

Ya-Qin Zhao et al.

Journal of fluorescence, 22(1), 485-494 (2011-09-29)

Centrin, an EF-hand calcium-binding protein with high homology to calmodulin (CaM), is an essential component of microtubule-organizing center (MTOC). Lanthanide (Ln) ions can improve the stability, increase the amount and enhance the orderliness of microtubules, which are components of cytoskeleton.

FBX aqueous chemical dosimeter for measurement of virtual wedge profiles.

Manoj K Semwal et al.

Journal of applied clinical medical physics, 9(4), 2809-2809 (2008-11-21)

We investigated the ferrous sulfate-benzoic acid-xylenol orange (FBX) aqueous chemical dosimeter for measurement of virtual (dynamic) wedge profiles on a linear accelerator. The layout for irradiation of the FBX-filled tubes mimicked a conventional linear detector array geometry. A comparison of
