Glioblastomas, the most malignant and prevalent brain tumors which remain incurable, are characterized by both extensive proliferation and invasive growth. We previously reported a remarkable antitumoral effect of the retinoid 6-OH-11-O-hydroxyphenantrene (IIF) on neuroblastoma, leukemia and colon carcinoma cells. In this study we examined the effect of IIF on proliferation, apoptosis and cell ...

INTRODUCTION Visual evaluation of indirect immunofluorescence (IIF) on human epithelial-2 cells is the routine method for screening for antinuclear antibodies (ANA) in connective tissue diseases. Since visual IIF is time-consuming and subjective, automated IIF processors have been developed to offer standardised, valid and cost-efficient IIF assays. OBJECTIVE The aim of this study was to dete...

With the launch of the first GPS IIF satellite, IIF-1 or SVN 62 on May 27, 2010, the U.S. GPS enters its midlife. The IIF-1 satellite is the very first GPS satellite with an operable L5 payload. The IIF-1 L1 and L2 signals were turned on June 6, 2010, and were set “healthy” on August 27, 2010. The satellite started to transmit L5 signal on June 17, 2010. We formed an international team of docto...

indirect immunofluorescence (iif) has been used to identify and measure autoantibody levels in pemphigus vulgaris but data about relationship between clinical severity of disease and antibody titers by iif have been conflicting. we conducted this cross-sectional study to correlate the severity of oral and/or cutaneous involvement in patients with pemphigus vulgaris based on pemphigus area and a...

Here we report the cellular arachidonate (AA)-releasing function of group IIF secretory phospholipase A(2) (sPLA(2)-IIF), a sPLA(2) enzyme uniquely containing a longer C-terminal extension. sPLA(2)-IIF increased spontaneous and stimulus-dependent release of AA, which was supplied to downstream cyclooxygenases and 5-lipoxygenase for eicosanoid production. sPLA(2)-IIF also enhanced interleukin 1-...

A method for the detection of infectious human rotaviruses based on infection of CaCo-2 cells and detection of infected cells by indirect immunofluorescence and flow cytometry (IIF-FC) has been developed. The technique was validated by performing a seminested reverse transcription-PCR assay with sorted cell populations. The efficiency of the procedure has been compared with that of the standard...

Objective. To retrospectively evaluate ANCA testing in a cohort of unselected Greek in- and outpatients. Methods. In 10803 consecutive serum samples, ANCA were tested by indirect immunofluorescence (IIF) and ELISA. ELISA in inpatients was performed only on IIF positive sera. Results. Low prevalence (6.0%) of IIF positive samples was observed. Among these samples, 63.5% presented perinuclear (p-...

OBJECTIVE To analyze indirect immunofluorescence (IIF) patterns and autoantibodies identified by line immunoassay (LIA) in rheumatoid arthritis (RA) patients, and to compare the autoantibody profiles with serological markers to determine their relevance. METHODS A total of 153 specimens were obtained from RA patients for diagnostic or monitoring purposes. Erythrocyte sedimentation rate (ESR),...

Our studies the past 5 yr have concentrated on intracellular ice formation (IIF) in mature mouse oocytes at the metaphase stage of meiosis II. Here we report an analogous investigation of the temperature of intracellular ice nucleation in preimplantation embryo stages from one-cell to early morula suspended in 1 M ethylene glycol/PBS and cooled at 20 degrees C/min to -70 degrees C. Physical mod...
