CD40 induces renal cell carcinoma-specific differential regulation of TRAF proteins, ASK1 activation and JNK/p38-mediated, ROS-dependent mitochondrial apoptosis.

A unique feature of CD40 among the TNF receptor (TNFR) superfamily is its exquisitely contextual effects, as originally demonstrated in normal and malignant B-lymphocytes. We studied renal cell carcinoma (RCC) in comparison to normal (human renal proximal tubule) cells, as a model to better understand the role of CD40 in epithelial cells. CD40 ligation by membrane-presented CD40 ligand (mCD40L), but not soluble CD40 agonist, induced extensive apoptosis in RCC cells; by contrast, normal cells were totally refractory to mCD40L.

Technical description and outcomes of a continuous anastomosis in open radical prostatectomy.

Objective: To describe the surgical technique, objective and subjective medium-term outcomes of a novel continuous vesico-urethral anastomotic suture in open radical prostatectomy (ORP).

Patients And Methods: A continuous anastomosis comprising separate anterior and posterior monofilament 3-0 polydioxanone sutures, with the bladder neck 'parachuted' down on to the urethral stump, was used in 39 consecutive patients. A cystogram was taken after ORP in the first 23 patients.
