Trail of Tears

The clinical trail of TRAIL.

The naturally occurring tumour necrosis factor related apoptosis-inducing ligand (TRAIL) induces apoptosis through two death receptors, death receptor 4 (DR4) and death receptor 5 (DR5), that are expressed on the cell membrane. Binding of the ligand to the death receptors leads to activation of the extrinsic apoptosis pathway. Chemotherapy on the other hand stimulates the intrinsic apoptosis pa...

Accuracy of SPECT bone scintigraphy in diagnosis of meniscal tears

Introduction: Scintigraphy has been considered as a useful tool in the assessment of meniscal tears. Our objective was to assess the accuracy of single photon emission tomography (SPECT), using MRI as the gold standard, in the diagnosis of meniscal tears. Materials and Methods: Between January 2003 and February 2005, 45 patients were studied with SPECT and MRI. Results: The respective sen...

Expression of TRAIL and TRAIL receptors in colon carcinoma: TRAIL-R1 is an independent prognostic parameter.

PURPOSE Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) selectively induces apoptosis in cancer cells and may be involved in protection from metastases. TRAIL receptor (TRAIL-R) 1 and TRAIL-R2, but not TRAIL-R3 and TRAIL-R4, mediate apoptosis. We examined the expression of TRAIL and its receptors in normal and neoplastic colon epithelium, and studied its correlation with prognos...

Meniscal tears

The menisci are two semilunar-shaped fibrocartilagenous structures, which are interposed between the femoral condyles and tibial plateaux. They have an important role in knee function. Long-term follow-up studies showed that virtually all meniscectomized knees develop arthritic changes with time. The meniscus has functions in load bearing, load transmission, shock absorption, joint stability, j...
