ABSTRACT Many institutions perform thoracoscopic surgery for pediatric extrapulmonary sequestration (EPS). This approach achieves good cosmetic outcomes due to the small skin incision in comparison open surgery. However, an extension or additional is sometimes necessary extract resected specimens from thoracic cavity, which reduces advantages of this procedure. We herein report 5 cases two‐site (TTS) using extraction wound with left‐sided EPS. In procedure, a camera port was inserted inside...

ABSTRACT Bronchial atresia (BA) and azygos lobe (AL) are rare congenital pulmonary abnormalities in pediatric patients. We herein report an infantile case of BA combined with AL that was treated thoracoscopic surgery. The patient 8‐month‐old boy who preoperatively diagnosed the right upper (RUL) using fetal magnetic resonance imaging postnatal enhanced computed tomography. Thoracoscopic surgery indocyanine green (ICG)‐guided near‐infrared fluorescence (NIRF) performed for RUL. In operative...

ABSTRACT Introduction Surgical procedures to avoid using artificial materials require ongoing discussion. We herein report a case of thoracoscopic repair for congenital diaphragmatic hernia (CDH) via anchor‐shaped closure with the patient's own residual diaphragm loop needle device. Patient and Technique A 2‐day‐old boy prenatally diagnosed CDH underwent after his respiratory circulatory conditions had stabilized. The defect was typical Bochdalek CDH, approximately 2.5 × 4 cm. herniated...

✓ The authors report five cases of surgically treated giant vertebral artery aneurysm. Two serpentine aneurysms were managed with aneurysmectomy, a semifusiform aneurysm trapping and partial the other two saccular clipping. Surgical results satisfactory in all cases. In particular, patients who underwent complete aneurysmectomy showed remarkable improvement after second procedure two-stage operation that consisted initial proximal occlusion secondary evacuation clots when advanced thrombosis...

To determine the possible role of Ca(++)-activated K+ (KCa) channels in regulation resting tone arteries, effects agents that interact with these on tension and 86Rb efflux were examined endothelium-denuded strips cerebral (middle cerebral, posterior basilar), coronary mesenteric arteries dog. Strips maintained a myogenic tone; i.e., decreased when either Krebs' solution was replaced Ca(++)-free or nifedipine added. The addition charybdotoxin, blocker large conductance KCa channels, to...

The brain cytoprotective effects of a putative calcium‐associated protein kinase inhibitor, HA1077, as well calcium entry blocker nicardipine were evaluated in models cerebral ischaemia Mongolian gerbils. Morphological changes characterizing delayed neuronal death selectively vulnerable CA 1 pyramidal neurones the hippocampus gerbil occurred 7 days after transient bilateral occlusion common carotid arteries. A single injection HA1077 (1 and 3 mg kg −1 , i.p.) 5 min led to dose‐dependent...

Metal-organic vapor-phase epitaxial (MOVPE) growth of InGaN and InAlN has been studied to prepare a wanted band-gap from 0.65 2.5 eV for multi-junction tandem solar cells. The main subjects in the are suppression phase separation metallic In incorporation control composition grown films. Both segregation can be avoided by choosing appropriate substrate position on susceptor. By optimizing temperature TMI/(TMI + TEG) molar ratio, films with full range successfully grown. Mg-doping behavior...

Abstract Introduction Management of neonates with long gap esophageal atresia (LGEA) is one the most challenging situations facing pediatric surgeons. Delayed anastomosis after internal traction for lengthening was reported as a useful technique cases. Additionally, use near‐infrared (NIR) fluorescence imaging indocyanine green (ICG) has gained popularity in surgery, especially blood perfusion validation. We report novel safe and secure LGEA neonatal period using ICG‐guided NIR fluorescence....

This paper reports on the development of a method for measuring xenon plasma properties using laser Thomson scattering technique, application to ion engine system design. The thresholds photo-ionization were investigated and number density metastable atoms, which are photo-ionized by probe laser, was measured absorption spectroscopy, several conditions. threshold energy plano-convex lens with focal length 200 mm 150 mJ mass flow rate 20 μg/s incident microwave power 6 W; therefore set as 80...
