A novel method for large-scale culture of anchorage-dependent cells is described. Culture vessels were constructed by using roller bottles and Pyrex tubing. Parallel glass tubes, equally spaced by silicone rings and inserted into the roller bottles, provided an increased culture area. The roller bottles were fitted with a second opening for medium recirculation. Culture vessels of 1,000-, 4,000...

The St Jude Medical Durata lead was produced in response to the recalled Riata and Riata ST leads in November 2011 after concerns of lead durability and inside-out abrasion. In order to protect against this susceptibility, the Riata ST Optim and Durata leads were coated with an abrasionresistant layer of silicone–polyurethane copolymer (Optim) tubing. We report a case of Durata lead extraction ...

Medical tapes and dressings are commonly used in hospitals to cover wounds and secure dressings or devices on patients’ skin. Repeated application and removal of medical adhesives may result in trauma to skin causing severe patient discomfort as well as expensive interventions. In this paper I will describe a new silicone-based medical adhesive that was designed to be gentle to sensitive skin w...

susceptibility testing revealed that the organism was 0. anthropi and that it was susceptible only to trimethoprim-sulfamethoxazole (TMP-SMZ), ciprofloxacin, imipenem, and gentamicin (the typical susceptibility pattern for this organism) [2]. The patient was treated with vancomycin, rifampin, ciprofloxacin, and TMP-SMZ for 6 weeks, followed by ciprofloxacin and TMP-SMZ for 4 1/2 months. Her wou...

The thromboresistance of 13 potentially blood-compatible polymers was assessed in sheep by determining survival of 51Cr-labeled platelets. Polymer tubing (120-150 cm x 2.0-2.3 mm i.d.) coiled around the neck was incorporated into the circulation through silicone rubber connectors as a carotid artery-external jugular vein shunt. The mean platelet half-life in control animals ("shunt control") wa...

A reliable and convenient system to generate accurate and stable standard gas mixtures of various atmospheric compounds at parts-per-billion levels has been developed. The system is of simple design; the generator is a coil consisting of an inner tube of microporous polytetrafuluoroethylene (PTFE) membrane tubing and an outer tube of silicone tubing. An aqueous solution of the given compound co...

history and objectives: insertion of intragastric tube through nose in infants for evaluation of congenital abnormalities of nose, esophagus and stomach in early hours after birth can lead to some complications (bradycardia, apnea and/or cyanosis) as a result of the stimulation of receptors of pharynx. this study was carried out to determine the complications in javaheri hospital affiliated to ...

A rigid-type of polyethylene T-cannula was fitted into the anterior ileum of six horses in order to improve the cannulation techniques. A piece of polyethylene net was fastened onto the intestinal wall around the cannula to prevent dislodgment of the cannula by promoting a secure adhesion between the ileum and the abdominal wall. The cannula barrel sheathed with silicone tubing was exteriorized...

BACKGROUND Chronic canaliculitis is often misdiagnosed as conjunctivitis, delaying proper documentation and management. Aggregatibacter aphrophillus has not been implicated in chronic canaliculitis. CASE PRESENTATION We report a case of unilateral chronic epiphora associated with chronic lacrimal canaliculitis resistant to prolonged topical antibiotic treatment in a 65-year-old woman without ...
