Delayed mesh infection and mesh penetrating the transverse colon and small intestine after abdominal incisional hernia repair.

The occurrence of late-onset mesh infection and mesh invasion into the intestine after abdominal incisional hernia repair is extremely rare. Herein, we describe the first case of late-onset mesh infection and mesh penetrating the transverse colon and small intestine 5 years after incisional hernia repair using an expanded polytetrafluoroethylene mesh. The symptom was drainage from the reddish wound, and computed tomography scan revealed intestinal prolapse with local wall thickening.

The Antioxidation Mechanism of Polydimethylsiloxane in Oil.

Strong and stable antioxidation effects of polydimethylsiloxane (PDMS) are widely accepted and utilized in commercial frying oil; however, the mechanism is not fully established. On the other hand, canola oil contains about 700 ppm (mg/kg-oil) of the natural antioxidant, tocopherol. Canola oil containing 0, 1 and 10 ppm added PDMS was heated at 180°C for 1 h under stirring, then left for 2-3 days at room temperature; this treatment was repeated 5 times.

Electrical stimulation of the rabbit pulmonary artery increases respiratory output.

This study was conducted to test the hypothesis that the pulmonary artery is involved in neural respiratory control and to identify the involved topographical region, if any. Six adult rabbits were anesthetized, artificially ventilated, and the chest was opened. The outer surface of the extra-pulmonary portion of the pulmonary artery was electrically stimulated by monitoring phrenic nerve activity.

Connective tissue-bone onlay graft with enamel matrix derivative for treatment of gingival recession: a case report.

We describe a case of gingival recession in which root coverage and coronal bone regrowth were achieved after treatment with a connective tissue-bone graft and enamel matrix derivative. The connective tissue-bone graft was harvested from a maxillary edentulous area and then curved to fit the root surfaces of the maxillary left central and lateral incisors. Enamel matrix derivative was applied to the root surfaces, and the connective tissue-bone graft was fixed to the interdental bone by a titanium screw.
