Among oxysterols oxidized at C7 (7alpha-, 7beta-hydroxycholesterol, and 7-ketocholesterol), 7beta-hydroxycholesterol and 7-ketocholesterol involved in the cytotoxicity of oxidized low density lipoproteins (LDL) are potent inducers of apoptosis. Here, we asked whether all oxysterols oxidized at C7 were able to trigger apoptosis, to stimulate interleukin(More)
The aim of the present study was to evaluate the resistance-associated mutations in 302 human immunodeficiency virus type 1 (HIV-1)-infected patients receiving combination therapy and monitored in Marseille, France, hospitals from January 1997 to June 1998. In the reverse transcriptase (RT) gene, the most frequent mutations were found at codons 215 (53%),(More)
OBJECTIVES The purpose of this study was to assess the value and limitations of Duke criteria for the diagnosis of infective endocarditis (IE). BACKGROUND Duke criteria have been shown to be more sensitive in diagnosing IE than the von Reyn criteria, but the diagnosis of IE remains difficult in some patients. METHODS Both classifications were applied in(More)
Micronucleated cell rates were assessed in cytokinesis-blocked lymphocytes of 198 male and female healthy subjects (HS) not occupationally exposed to genotoxic risks and of 70 male and female cancer patients (CP) prior to any anticancer treatment. In the HS group, spontaneous micronucleated cell rates (MN cell rates) were 9.7 +/- 2.8 per 1000 binucleated(More)
We investigated whether head-and-neck cancers are associated with an increased micronucleated cell rates (MN cell rates) and whether risk factors for these cancers are associated with alterations in micronucleated lymphocytes. MN cell rates were assessed in cytokinesis-blocked lymphocytes of 57 head-and-neck cancer patients (CP) before any anticancer(More)
PURPOSE To evaluate the prevalence of the intervertebral vacuum phenomenon in disks adjacent to vertebral collapses of various causes. MATERIALS AND METHODS The authors retrospectively studied 310 consecutive patients who had at least one vertebral collapse. The vacuum phenomena were divided into collapse-related (ie, adjacent to a collapse) and(More)
BACKGROUND We previously demonstrated that minimally invasive video-assisted parathyroidectomy (VAP) can be performed via a lateral approach on the line of the sternocleidomastoid muscle. The aim of this study was to compare the results of this technique with those of conventional parathyroidectomy (CP) in a case-control study. METHODS Over a 2-year(More)
In this retrospective analysis, we report on the detailed management of 33 recurrent osteosarcoma patients from a population of 81 adolescents and adults previously treated (between November 1979 and November 1998) at the La Timone Adults Hospital, for an extremity-localised osteosarcoma. The site of the first recurrence was limited to the lung in 24(More)
BACKGROUND Osteosarcomas typically are long bone tumors and rarely affect the flat bones of the axial or appendicular skeleton. METHODS The authors examined cases of high grade osteosarcoma of flat bones diagnosed at La Timone Adults University Hospital during a 16-year period. RESULTS Sixteen patients with flat bone osteosarcomas were treated between(More)
In order to clarify the coagulation profile accompanying ischemic stroke, which may have implications on therapeutic strategies, we performed a prospective study to evaluate the hemostatic parameters in the first 24 h after the onset of cortical atherothrombotic infarct and lacunar infarction. Twenty-seven patients with cortical atherothrombotic infarction(More)
