We have developed a dual-chamber microfluidic microbial fuel cell (MFC) system that allows on-chip bacterial culture and conversion of bacterial metabolism into electricity. The micro-MFC contains a vertically stacked 1.5 microL anode chamber and 4…

A ditopic hydrogen-bond-donor template in the form of resorcinol facilitates a 2+2 cross-photodimerisation of 4-Cl-stilbazole and 4-Me-stilbazole in a rare cocrystal solid solution. A photoreaction does not proceed with the olefins individually or…

To examine the possible repeated-dose toxicity of an ultraviolet absorber, 2-(2'-hydroxy-3',5'-di-tert-butylphenyl)benzotriazole (HDBB), CD(SD)IGS rats were administered HDBB by gavage at a dose of 0 (vehicle: corn oil), 0.5, 2.5, 12.5, or 62.5 mg…

The morphological behaviour of poly(ether-urethane)s undergoing deformation was studied using two-dimensional small-angle X-ray scattering (2D-SAXS). The data was analysed using the Zernike-Prins and Percus-Yevick models, which fitted the data well…

Three-dimensional (3D) organotypic culture models based on human cells may reduce the use of complex and costly animal models, while gaining clinical relevance. This study aimed at developing a 3D osteoblastic-osteoclastic-endothelial cell…

Injection molding is one of the most widely used plastic part processing. The quality of the injection molded part is a function of plastic material, part geometry, mold structure and process conditions. Gate location is among the most critical…

Fabrication of posts and cores for fixed partial denture (FPD) and removable partial denture (RPD) abutment restorations is common in dentistry. The biocompatibility of various post and core techniques with the restorations was clinically evaluated…

Sequence control in chain-growth polymerization is still one of the most challenging topics in synthetic polymer chemistry in contrast to natural macromolecules with completely sequence-regulated structures like proteins and DNA. Here, we report the…

Under physiological conditions, a protein undergoes a spontaneous disorder order transition called folding. The protein polymer is highly flexible when unfolded but adopts its unique native, three-dimensional structure when folded. Current…

Triblock copolymers (or, alternatively, terpolymers) of the type ABC, where A, B, and C represent distinct blocks based on different monomers, have been prepd. using atom transfer radical polymn. (ATRP) techniques. Various macroinitiators, including…

Polymer vesicles made from poly(isoprene-b-styrene-b-2-vinyl pyridine) (PI-b-PS-b-P2VP) triblock copolymer confined within the nanopores of an anodic aluminum oxide (AAO) membrane are studied. It was found that these vesicles have well-defined,…

BACKGROUND: Alternatives to fascial closure of the abdominal wall are increasingly used in critically ill patients. They pose practical and logistical problems in management which are described in this single-institution study. METHODS: Between…

For a better understanding of the cytological principles involved in the formation of reactive membranes on lens implants in the human eye, two kinds of modern implants were placed into the peritoneal space of mice. Continuous membranes mainly…

A woman in her 34th week of gestation required emergency appendectomy for perforation, with postoperative wound dehiscence secondary to fasciitis and tension on the suture line. Polypropylene mesh was used to repair the abdominal wall. Fetal…

A midline abdominal wound was made in 135 Harlan Sprague-Dawley rats, and the fascia was then closed by the continuous suture technique with 4-0 absorbable monofilament polydioxanone sutures (n = 45 rats), 4-0 permanent monofilament polypropylene…

The incidence of wound infection, burst abdomen and incisional herniation after a vertical abdominal incision was studied in a prospective trial comparing polypropylene (Prolene) with polyglycolic acid (Dexon). Wounds were closed by interrupted mass…
-
We report our experience with 1,000 consecutive abdominal wound closures using continuous monofilament polypropylene (Prolene) sutures. Wound dehiscence occurred in four patients (0.4%), and incisional hernia occurred in seven patients (0.7%). The…

Platelets for transfusion, stored in either of two new types of container (PL-732 and CLX), demonstrated unusual morphological alterations after 2 or 3 days of storage. The atypical forms observed included crescents, elongated tubular forms and…

High levels of acrolein (H2C=HC-CH=O) occur in Alzheimer's brain. Amyloid-beta (Abeta) peptide co-localizes with acrolein presumably due to Abeta-induced lipid peroxidation. Focal production of acrolein may yield a transient elevation in the…
