objective(s) studies have described immunomedulatory effects of sun exposure and ultraviolet radiation on infectious and neoplastic diseases. here the effect of exposure to low potency radiation of sun on the course of leishmaniasis in mice was studied. materials and methods fifteen balb/c mice were exposed to suberythemogenic doses of sun (mean 180 mj/cm2/day of uvb) 2 months before and 4 mont...

Results: Response of skin warty lesions to treatment with intralesional 5-FU was as following: complete response was seen in 200 (80.0 %), partial response was seen in 37 (14.8 %) of cases and no response was recorded in 13 (5.2 %) of cases. There was no significant association between size of warty lesion and response to intralesional 5-FU (p = 0.154), but there was significant association bet...

INTRODUCTION This study retrospectively evaluated CT-guided thoracic biopsies for diagnostic yield, accuracy and complications. MATERIALS AND METHODS A retrospective analysis of 384 patients (mean age 62.7 years; male/female = 251/133) who underwent 399 CT-guided thoracic biopsies were performed for evaluating diagnostic yield, accuracy and complications. Correlations between patients age, pr...

OBJECTIVE: Treatments for articular cartilage lesions could benefit from characterization of lesion patterns and their progression to end-stage osteoarthritis. The objective of this study was to identify, quantitatively, topographic patterns of cartilage lesions in the human knee. DESIGN: Photographs were taken of 127 unilateral distal femora (from 109 cadavers and 18 arthroplasty remnants) wit...

BACKGROUND AND PURPOSE The arterial input function (AIF) is critical in determining hemodynamic parameters quantitatively with bolus-tracking MRI. We studied the effect of varying the location of measurement of AIF on the volume of hypoperfusion. We compared the volumes of hypoperfusion obtained with different AIFs with the final ischemic lesion volume. METHODS We included 13 patients with ac...

SUMMARY In this study, we compared lesion size by using VADC and VT2 at 0, 2, 5, 24, and 48 hours and histologic lesions at 48 hours in a P7 rat stroke model. The best correlation between VHISTO and VADC was at H0, and between VHISTO and VT2, at H2-H5. Early MR imaging signals allowed excluding "no-lesion" and "no-reflow" animals to help standardize this neonatal stroke model and predict lesion...
