the down-flow hanging sponge (dhs) reactor, which was developed for post-treatment of effluent from up-flow anaerobic sludge blanket (uasb) process treating sewage, uses polyurethane sponge as media to retain biomass. wastewater is trickled from the top of the reactor and purified by microorganisms retained both inside and outside of the sponge media as the wastewater flows vertically down thr...

BACKGROUND The aim of our study was to compare the efficacy and safety of: 1) transarterial chemolipiodolization with gelatin sponge embolization vs chemolipiodolization without embolization, and 2) chemolipiodolization with triple chemotherapeutic agents vs epirubicin alone. METHODS A single-blind, three parallel arm, randomized trial was conducted at three clinical centers with patients wit...

Angiogenesis represents an excellent therapeutic target for the treatment of cardiovascular diseases. It is a potent physiological process that underlies the natural manner in which our bodies respond to a diminution of blood supply to vital organs, namely the production of new collateral vessels to overcome the ischemic state. This present study is aimed to evaluate and quantify the Angiogenic...

Injury to growth plate cartilage in children can lead to bone bridge formation and result in bone growth deformities, a significant clinical problem currently lacking biological treatment. Mesenchymal stem/stromal cells (MSC) offer a promising therapeutic option for regeneration of damaged cartilage, due to their self renewing and multi-lineage differentiation attributes. Although some small an...

The patient was a 19-year-old man who was examined due to persistent penile erection, which appeared following a blow to the perineal region during work. Color Doppler ultrasonography of the corpora cavernosa revealed a cavity in one part of the cavernous artery that suggested a blood leak, and a diagnosis of high flow type priapism due to trauma was made. Bilateral internal pudendal arteriogra...

OBJECTIVE To determine the frequency, character, methods of treatment, and outcome of ischemic complications after transcatheter hepatic artery chemoembolization (TACE). MATERIAL AND METHODS Between 1985 and 1998, 827 sessions of TACE with Doxorubicin mixed with iodized oil, and gelatin sponge particles were performed in 282 patients with primary and metastatic liver cancer. Post-TACE monitor...

OBJECTIVE Cerebrospinal fluid leakage is the most common complication of endoscopic trans-sphenoidal pituitary surgery. However, there is no uniformly accepted way of managing this complication when it occurs intra-operatively. This paper describes a quick, simple technique, involving layered fibrin glue and gelatin sponge, which does not compromise post-operative patient follow up. METHOD Re...

Uterine necrosis after uterine artery embolization (UAE) for postpartum hemorrhage (PPH) is relatively rare. A 29-year-old primiparous woman had a diamniotic dichorionic twin pregnancy following frozen blastocyst transfer. She developed preeclampsia at 34+3 weeks, and cesarean section was performed due to lung edema 35+2 weeks. UAE using gelatin sponge 3 hours the operation PPH; however, contin...
