This study was aimed at evaluating the digestive tolerance of the new antiosteoporotic drug, strontium ranelate, and to compare it to that of another strontium salt, strontium chloride (SrCl2). Strontium ranelate, SrCl2, or placebo were administered orally (capsules) to 3 groups of 2 male and 2 female cynomolgus monkeys (Macaca fascicularis) once a day for(More)
An ultrasonographic urinary bladder morbidity score was developed and tested in 510 patients with schistosomiasis haematobia, and then evaluated for screening 1,134 randomly selected children from villages endemic for Schistosoma haematobium. The ultrasonographic urinary bladder morbidity score had four grades ranging from normal to marked thickening of the(More)
The aim of this study was to analyze the association of hepatocellular carcinoma (HCC) with hepatitis C virus (HCV) in Egypt, using hepatitis B virus (HBV) and hepatitis E virus (HEV) as virus controls. In addition, the association of HCC with HCV RNA levels among persons seropositive for HCV was analyzed. We compared 131 patients with proven HCC, 247 with(More)
Serum samples from 429 cancer patients, 82 unpaid blood donors, and 74 paid blood donors were tested for hepatitis C virus (HCV) markers in two commercially available enzyme immunoassays (EIAs). A total of 229 of 429 (53.4%) cancer patients were positive by the two EIAs. A total of 34 of 156 (21.8%) of the blood donors were positive by the EIAs, with a(More)
The carcinogenic potential in the intraperitoneal cavity of three newly developed biosoluble insulation glass wool fibers (M, P, and V) and one newly developed biosoluble insulation stone wool fiber (O) was investigated and compared to that of a previously developed soluble glass fiber (B). The in vitro dissolution coefficient of the three glass wool fibers(More)
Research has focused on static large graph management. However, most of real-world networks evolve with time. Managing these evolving networks has attracted much attention in recent years. The networks' evolved data can be kept in a dynamic graph to improve the expressiveness and the quality of search queries as well as snapshot(s) retrieval. Storing the(More)
The objective of the study is to assess the role of diode laser coupled with topical mitomycin C (MMC) in the management of synechia after endoscopic sinus surgery. Twenty-five patients with recurrent sinusitis due to synechia between the middle turbinate and lateral nasal wall after endoscopic sinus surgery were included in this study. Diode laser was used(More)
Abstarct Visual features are used extensively to compose image signatures in content based image retrieval systems CBIR. Although the retrieval quality is sufficient for some tasks and the automatic extraction of visual features is rather convenient, there is still a semantic gap between the low-level visual features (textures, colors) automatically(More)
The ovariectomized old cynomolgus monkey is a recognized model of human osteoporosis, and the same species can be used for the assessment of the efficacy and potential toxicity of agents intended to prevent or treat osteoporosis. Several assays have been developed that can measure the same biochemical markers of bone turnover as are used in human patients(More)
