While it has been established that anti-phospholipid antibodies (aPL) are associated with recurrent miscarriage (RM), the importance of anti-beta2 glycoprotein 1 (GP1) IgG and anti-annexin V IgG antibodies as risk factors for RM is undefined. We have investigated the prevalence of anti-beta2 GP1 IgG and anti-annexin V IgG antibodies in 54 aPL-positive and 48 aPL-negative women with RM. The prev...

BACKGROUND We wished to determine the ability of radiolabeled annexin V to concentrate at sites of ischemic injury in patients with acute cerebral stroke. Secondly, we sought to correlate annexin V imaging in these patients with the degree of blood-brain barrier (BBB) breakdown. METHODS Twelve patients with acute stroke had a complete neurological examination, including the National Institute...

BACKGROUND The aim of the present study was to define the effect of apoptosis on sperm quality and function. METHODS The apoptotic features in sperm were assessed in 60 subfertile subjects, using Annexin-V staining for phosphatidylserine (PS) externalization and Tdt-mediated dUTP nick end labelling (TUNEL) assay for DNA fragmentation. RESULTS On average, about 45% of the sperm were found to...

BACKGROUND The aim of the study is to detect apoptosis in granular cell ameloblastoma by annexin v affinity assay, a novel technique. MATERIALS & METHODS Excitional biopsy of two patients with granular cell ameloblastoma were fixed in buffered formalin and later embedded in paraffin wax. Blocks were sliced into 3m thick sections for routine histological and subsequent immunohistochemical exam...

Induction of apoptosis is the primary mechanism through which most chemotherapies cause tumor cell death. Early assessment of tumor response is required to manage patients in terms of quality of life versus intensive chemotherapy. Although imaging with radiolabeled annexin V has been intensively investigated, it is still not sufficiently mature for clinical application. This article will summar...

PURPOSE To develop a technology to image cell death in the eye of a live mouse and to apply that technology to characterize the role of apoptosis and necrosis in the evolution of endotoxin-induced uveitis (EIU), a standard model of intraocular inflammation. METHODS To induce EIU, 250 ng Escherichia coli 055:B5 lipopolysaccharide was injected into the vitreous body of BALB/c mice. At 0, 6, 10,...
