This paper describes a light-addressed electrolytic system used to perform an electrodeposition of enzyme-entrapped chitosan membranes for multiplexed enzyme-based bioassays using a digital micromirror device (DMD). In this system, a patterned light illumination is projected onto a photoconductive substrate serving as a photo-cathode to electrolytically produce hydroxide ions, which leads to an...

Polypectomy-snare entrapment is a rare but serious complication of colonoscopy, frequently requiring surgical intervention. We report a case of polypectomysnare entrapment successfully treated using a novel endoscopic “zip-line” approach that, to our knowledge, has not been previously reported. A 35-year-old woman underwent a colonoscopy in our office-endoscopy suite, during which a 4 cm, broad...

The association of carboxymethyl starch (CMS) and alginate is proposed as a novel matrix for the entrapment of bioactive agents in microspheres affording their protection against gastrointestinal degradation. In this study, the enzyme diamine oxidase (DAO) from white pea (Lathyrus sativus) was immobilized by inclusion in microspheres formed by ionotropic gelation of CMS/alginate by complexation...

Cross-linked nanoassemblies (CNAs) with a degradable core were prepared for sustained release of 17-N-allylamino-17-demethoxygeldanamycin (17-AAG), a potent inhibitor of heat shock protein 90 (HSP90). The particle size of CNAs ranged between 100 and 250 nm, which changed depending on the cross-linking yields and drug entrapment method. CNAs with a 1% cross-linking yield entrapped 17-AAG in aque...

Protease production by Bacillus subtilis with free and immobilized cells was examined in this study. Entrapment method of immobilization was used with gelatin, polyacrylamide, calcium alginate and agar matrices and protease production was studied compared to equivalent weight of free cells. Results showed that the gelatin entrapped cells produce 10.8 U/ml; the maximum enzyme titer followed by p...

Gases contained within near-surface marine sediments can be derived from multiple sources: shallow microbial activity, thermal cracking of organic matter and inorganic materials, or magmatic-mantle degassing. Each origin will display a distinctive hydrocarbon and non-hydrocarbon composition as well as compound-specific isotope signature and thus the interpretation of origin should be relatively...

INTRODUCTION Entrapped thrombus in a patent foramen ovale is a rare form of right heart thromboembolism. Various treatments have been used, such as anti-coagulation and thrombolytic therapy, vena cava filter, percutaneous thrombectomy and surgical embolectomy. CASE PRESENTATION A 60-year-old Kosovan woman was admitted to our hospital with a massive bilateral pulmonary thromboembolism, entrapp...

We report biocompatible, cell-permeable core-shell-corona polymer micelles bearing glutathione-cleavable shell cross-links, which allow the facilitated release of entrapped anticancer drugs at cytoplasm in response to an intracellular glutathione level.

[ -H] Methotrexate ([ -H]MTX) was entrapped inside sonically disrupted, positively charged, [14C]cholesterol-labeled liposomes. Its distribution and metabolic integrity was then studied after a single injection into the cérébrospinal fluid (CSF) in the lateral cerebroventricles of cynomolgus monkeys (Macaca fascicularis). Between 24 and 96 hr after injection, a maximal 4-fold increase in aver...

Pot experiments showed that Rhizobium japonicum cells entrapped in a polyacrylamide gel could be used as an inoculant for soybeans and compared favorably to laboratory-made peat base inoculant containing the same bacterial strain.
