The safety and feasibility of thoracoscopic uncommon pulmonary segmentectomy.

Backgrounds: Opportunities to treat patients requiring uncommon pulmonary segmentectomy are increasing because small pulmonary nodules are being incidentally detected more often. Uncommon segmentectomy is frequently performed via thoracotomy because uncommon pulmonary segmentectomies are associated with various technical difficulties compared to common segmentectomies. In this study, we investigated the safety and feasibility of thoracoscopic uncommon segmentectomy.

The efficacy of thoracoscopic fissureless lobectomy in patients with dense fissures.

Background: Prolonged air leakage after a lobectomy remains a frequent complication in patients with dense fissures. To avoid postoperative air leakage, we used the "thoracoscopic fissureless technique" for patients with dense fissures. A thoracoscopic approach is useful for the fissureless technique because it gives a good operative view from various angles without dividing the fissure.

Troubleshooting for bleeding in thoracoscopic anatomic pulmonary resection.

Introduction The objective of this study was to evaluate intraoperative vessel injury and assess troubleshooting during thoracoscopic anatomic pulmonary resection. Methods Between April 2012 and March 2016, 240 patients underwent thoracoscopic anatomic lung resection, 26 of whom were identified as having massive bleeding intraoperatively. We analyzed the injured vessel and the hemostatic procedure employed, then compared the perioperative outcomes in patients with ( n = 26) and without ( n = 214) vessel injury.

Efficient production of L-lactic acid by Crabtree-negative yeast Candida boidinii.

Industrial production of L-lactic acid, which in polymerized form as poly-lactic acid is widely used as a biodegradable plastic, has been attracting world-wide attention. By genetic engineering we constructed a strain of the Crabtree-negative yeast Candida boidinii that efficiently produced a large amount of L-lactic acid. The alcohol fermentation pathway of C.

Characterization of vps33+, a gene required for vacuolar biogenesis and protein sorting in Schizosaccharomyces pombe.

From the fission yeast Schizosaccharomyces pombe we have identified and deleted vps33, a gene encoding a homologue of VPS33, which is required for vacuolar biogenesis in S. cerevisiae cells. When the vps33(+) gene is disrupted, Sz.
