The movement of water between microenvironments presents a central challenge in the physics of soft matter and porous media. Diffusion exchange spectroscopy (DEXSY) is a powerful 2D nuclear magnetic resonance method for measuring such exchange, yet it is rarely used because of its long scan time requirements. Moreover, it has never been combined with magnetic resonance imaging (MRI). Using prob...

We describe three cases of submacular hemorrhage that occurred two to four days after anti-VEGF intravitreal injection for occult choroidal neovascularisation in age-related macular degeneration and their management with 25 gauge pars plana vitrectomy with injection of subretinal recombinant tissue plasminogen activator (rTPA) followed by fluid-air exchange and postoperative prone position. Vit...

The two-stage exchange arthroplasty (one- or two-stage) is believed to be the gold standard for the management of infections following total knee arthroplasty. We herein report a novel two-stage exchange arthroplasty technique using an antibiotic-impregnated cement intramedullary nail, which can be easily prepared during surgery using a straight thoracic tube and a Steinmann pin, and may provid...

1. Goat kidney ,J-mannosidase was purified 8500-fold to a specific activity of 65000 nmol/h per mg of protein with a 6% yield by using multiple steps including cation-exchange and anion-exchange fast protein liquid chromatography. This is the first description of a highly purified preparation from goat tissue; however, it was not homogeneous, as judged by silver-stained SDS/polyacrylamide-gel e...

Tracheostomy tube change is a relatively common and simple procedure once a tract is formed between the skin and the trachea. Regular tracheostomy tube changes decrease the risk of postoperative pulmonary infection and granulation tissue formation. However, serious complications, such as loss of airway, subcutaneous emphysema, and mediastinitis, can occur if the tube exchange is performed inapp...

A common sequence for performing staged tissue expander breast reconstruction is to immediately insert a tissue expander, complete expansion before radiotherapy, and then perform the definitive reconstruction after radiotherapy is complete. This study evaluates the outcomes of this treatment regimen in 237 patients over a 10-year period at Northwestern Memorial Hospital. Overall, 62% of the pat...

BACKGROUND Electrochemotherapy is an effective approach in local tumour treatment employing locally applied high-voltage electric pulses in combination with chemotherapeutic drugs. In planning and performing electrochemotherapy a multidisciplinary expertise is required and collaboration, knowledge and experience exchange among the experts from different scientific fields such as medicine, biolo...

OBJECTIVE Our aim was to develop a mathematical model that describes the nitric oxide (NO) transport in and around capillaries. The model is used to make quantitative predictions for (1) the contribution of capillary endothelium to the nitric oxide flux into the parenchymal tissue cells; (2) the scavenging of arteriolar endothelium-derived NO by capillaries in the surrounding tissue; and (3) th...
