BACKGROUND We recently showed that IGFBP2 is overexpressed in primary lung cancer tissues. This study aims to determine whether IGFBP2 is elevated in blood samples of lung cancer patients and whether its level is associated with clinical outcomes. METHODOLOGY/PRINCIPAL FINDINGS Plasma IGFBP2 levels were determined blindly by enzyme-linked immunosorbent(More)
Insulin-like growth factor (IGF)-binding protein-2 (IGFBP2) expression is increased in various types of cancers, including in a subset of patients with lung cancer. Because IGFBP2 is involved in signal transduction of some critical cancer-related pathways, we analyzed the association between IGFBP2 and response to pathway-targeted agents in seven human(More)
Ibrutinib, which irreversibly inhibits Bruton tyrosine kinase, was evaluated for antitumor activity in a panel of non-small cell lung cancer (NSCLC) cell lines and found to selectively inhibit growth of NSCLC cells carrying mutations in the epidermal growth factor receptor (EGFR) gene, including T790M mutant and erlotinib-resistant H1975 cells. Ibrutinib(More)
Deep-freezing, freeze-drying and gamma (γ)-irradiation have deleterious effects on bone healing and mechanical properties of allograft bones. We tried preparing bone allografts using cyclosporine plus low-temperature-plasma sterilization. To explore the feasibility of this method of preparation, segmental defects in the right radii of rabbits were repaired(More)
For the generalized linear model, the authors propose a sequential sampling procedure based on an adaptive shrinkage estimate of parameter. This method can determine a minimum sample size under which effective variables contributing to the model are identified and estimates of regression parameters achieve the required accuracy. The authors prove that the(More)
AIMS This study aimed to assess whether transcutaneous oxygen tension (TcPO2) was associated with the presence of microvascular complications in type 2 diabetic (T2D) patients and whether TcPO2 could act as an independent risk factor for predicting the occurrence of microvascular events in these patients. METHODS We recruited 436 patients with T2D. Based(More)
BACKGROUND Freeze-dried and irradiated allograft bone (FIAB) is more easily impacted than fresh-frozen allograft bone (FAB) but has weaker incorporation efficiency. We combined FIAB with fresh autologous coagula to enhance donor-host incorporation after impaction during hip revision. METHODS Thirty adult male Sprague-Dawley rats were sacrificed for bone(More)
In this paper, the existence of step-like contrast structure for a class of singularly perturbed optimal control problem is shown by the contrast structure theory. By means of direct scheme of boundary function method, we construct the uniformly valid asymptotic solution for the singularly perturbed optimal control problem. Finally, an example is presented(More)
