BACKGROUND Biodegradable hydrogels can deliver therapeutic payloads with great potentials in EMR and endoscopic submucosal dissection (ESD) to yield improvements in efficacy and foster mucosal regeneration. OBJECTIVE To assess the efficacy of an injectable drug-eluting elastomeric polymer (iDEEP) as a submucosal injection material. DESIGN Comparative study of 3 different solutions by using ...

PURPOSE To introduce a practical method of subretinal injection in mice and evaluate injection-induced retinal detachment (RD) and damage using a dynamic imaging system, electrophysiology, and histology. METHODS After full dilation of a 2-month-old C57BL/6J mouse pupil, the cornea near the limbus was punctured with a 30 ½-gague disposable beveled needle. A 33 ½-gauge blunt needle was inserted...

One of the mostly used enhanced oil recovery methods is the injection of water or gas under pressure to maintain or reverse the declining pressure in a reservoir. Several parameters should be optimized in a fluid injection process. The usual optimizing methods evaluate several scenarios to find the best solution. Since it is required to run the reservoir simulator hundreds of times, the process...

I performed a transperineal intraprostatic injection of botulinum toxin type A (BT-A) with a dosage of 1000 units of DysportTM/ Ipsen diluted in 0.5% adrenaline solution of water for injection, in a single injection directly between the two apparent hypoechoic areas under transrectal ultrasound (TRUS) guidance, in a total volume of 7 cm3, in order to relieve his ongoing prostatic obstruction. (...

Unilobar injection of starch solution produced pulmonary infarction at the site of injection and diffuse bilateral pulmonary edema. The predominantly or entirely unilobar distribution of the embolizing material was established by histologic methods and by a technic using whole lung lobe suspension stained with Lugol's solution. Evidence is presented suggesting that the pulmonary edema in the no...

The four major categories of skill sets associated with proficiency in ultrasound guided regional anaesthesia are 1) understanding device operations, 2) image optimization, 3) image interpretation and 4) visualization of needle insertion and injection of the local anesthetic solution. Of these, visualization of needle insertion and injection of local anaesthetic solution can be practiced using ...

MITTENT" AND "REMITTENT" FEVERS BY THE HYPODERMIC INJECTION OF QUININE. By Assistant Surgeon, John Candy, M.D., 109^/t Regiment. During the past year, I have made careful observations on the treatment of "intermittent fever" by the hypodermic injection of quinine. The first eight cases were injected in the arm, at the insertion of the deltoid, with a solution of quinine dissolved by the aid of ...

We have developed a consecutive sample-injection device for capillary electrophoresis, which comprises one four-way cock, two syringe pumps, and an interface part taking advantage of two three-way Teflon joints. Sample introduction into the capillary is made hydrodynamically by pressure, caused by the flow of the sample solution at the tip of the capillary inlet. We combined the injection devic...
