We retrospectively analysed 106 consecutive traumatic humeral shaft fractures over a five-year period. The mechanism of injury, age, gender, fracture types, associated injury and the presence of injury to the radial nerve were reviewed. The incidence was about 10 per 100,000 per year; most were closed fractures in young males which had been sustained as a(More)
Osteosarcoma is characterized by a high malignant and metastatic potential. The chemokine stromal-derived factor-1alpha (SDF-1alpha) and its receptor, CXCR4, play a crucial role in adhesion and migration of human cancer cells. Integrins are the major adhesive molecules in mammalian cells, and has been associated with metastasis of cancer cells. Here, we(More)
BACKGROUND Fat embolism syndrome (FES) is a potentially fatal complication of long bone fractures. There have been no reports of FES in long bone fractures in this decade in Taiwan. The purpose of this study was to review the FES experiences in a tertiary referral center between January 1997 and February 2008. METHODS Between January 1997 and February(More)
OBJECTIVE To explore the possible mechanisms of spermatogenic arrest in severe oligoasthenoteratozoospermia induced by supernumerary, ring-neocentric 13q12.3 --> 13q22 chromosome and reciprocal deletion. METHODS We performed a genomic-wide high-density oaCGH analysis for a case of oligoasthenoteratozoospermia with abnormal chromosome 13 to characterize(More)
Leaf variegation is often the focus of plant breeding. Here, we studied a variegated mutant of Phalaenopsis aphrodite subsp. formosana, which is usually used as a parent of horticultural breeding, to understand its anatomic and genetic regulatory mechanisms in variegation. Chloroplasts with well-organized thylakoids and starch grains were found only in the(More)
Adrenoleukodystrophy (ALD) is a rare and progressive neurogenetic disease that may manifest disparate symptoms. The present study aims at investigating the role of ataxic variant of ALD (AVALD) in patients with adult-onset cerebellar ataxia, as well as characterizing their clinical features that distinguish AVALD from other cerebellar ataxias. Mutations in(More)
Both poly(ethylene glycol) (PEG) grafting and layer-by-layer polyelectrolyte multilayer (PEM) deposition for surface modification of biomaterials have been shown to decrease cell adhesion. The aim of this study was to investigate the synergic efficacy of PEGylated PEM films on reducing cell adhesion. PEG grafted to poly(ethylene imine) (PEI) was deposited(More)
