The First Application of Intraumbilical Longitudinal Incision to Pyloromyotomy for Hypertrophic Pyloric Stenosis.

Objective: There are several approaches to pyloromyotomy for the treatment of hypertrophic pyloric stenosis including open transumbilical pyloromyotomy and laparoscopic pyloromyotomy. Beginning in 2012, we adopted intraumbilical longitudinal incision as a new transumbilical approach for pyloromyotomy. We describe details of the operative technique and results of this new approach.

House mouse Mus musculus dispersal in East Eurasia inferred from 98 newly determined complete mitochondrial genome sequences.

The Eurasian house mouse Mus musculus is useful for tracing prehistorical human movement related to the spread of farming. We determined whole mitochondrial DNA (mtDNA) sequences (ca. 16,000 bp) of 98 wild-derived individuals of two subspecies, M.

Digestive Reconstruction After Pharyngolaryngectomy with Total Esophagectomy.

Background: Pharyngolaryngectomy with total esophagectomy (PLTE) is often indicated for patients with synchronous head and neck cancer and thoracic esophageal cancer or those with head and neck cancer extending to the upper mediastinum. A long conduit is required for the reconstruction, and the blood flow at the tip of the conduit is not always sufficient. Thus, reconstructive surgery after PLTE remains challenging, and optimal reconstruction methods have not been elucidated to date.

Fabrication of an anatomy-mimicking BIO-AIR-TUBE with engineered cartilage.

Introduction: We devised a strategy for the fabrication of an 'anatomy-mimicking' cylinder-type engineered trachea combined with cartilage engineering. The engineered BIOTUBEs are used to support the architecture of the body tissue, for long-segment trachea (>5 cm) with carinal reconstruction. The aim of the present study was to fabricate an anatomy-mimicking cylinder-type regenerative airway, and investigate its applicability in a rabbit model.
