OBJECTIVE Our aim was to determine the Toxoplasma gondii IgG seroprevalence in HIV/AIDS patients who applied to our outpatient clinic. METHODS Between January 2006 and June 2010, 164 HIV/AIDS patients were tested for Toxoplasma gondii IgG antibodies by using the ELISA method. RESULTS Of the total of 164 HIV/AIDS patients, 135 were male, 29 were female with a mean age of 36 years (range: 20-...

Aims. Spectroscopic monitoring of BL Lac objects is a difficult task that nonetheless can provide important information on the different components of the active galactic nucleus. Methods. We performed optical spectroscopic monitoring of the BL Lac object AO 0235+164 (z = 0.94) with the VLT and TNG telescopes from Aug. 2003 to Dec. 2004, during an extended WEBT campaign. The flux of this source...

We report seven successful observations of the astrometric binary GJ 164 AB system with aperture masking interferometry. The companion, with a near infrared contrast of 5:1 was detected beyond the formal diffraction limit. Combined with astrometric observations from the literature, these observations fix the parallax of the system, and allow a model-independent mass determination of both compon...

Much important information can be obtained at necropsy by the pathological examination of the eye and its adnexal structures in adults and children. This information may be related to the cause of death (for example, violent shaking trauma in physical child abuse), or may pertain to disease processes aVecting the eye, the orbit, and surrounding structures outside the orbit. This article reviews...

PURPOSE Virtual colonoscopy is the most recently developed tool for detecting colorectal cancers and polyps, but its effectiveness is limited. In our study, we compared the result of preoperative virtual colonoscopy to result of preoperative and postoperative colonoscopy. We evaluated also the accuracy of preoperative virtual colonoscopy in patients who had obstructive colorectal cancer that di...
