Strain-invariant stretchable radio-frequency electronics.

Wireless modules that provide telecommunications and power-harvesting capabilities enabled by radio-frequency (RF) electronics are vital components of skin-interfaced stretchable electronics. However, recent studies on stretchable RF components have demonstrated that substantial changes in electrical properties, such as a shift in the antenna resonance frequency, occur even under relatively low elastic strains. Such changes lead directly to greatly reduced wireless signal strength or power-transfer efficiency in stretchable systems, particularly in physically dynamic environments such as the surface of the skin.

Vitamin D binding protein plays an important role in the progression of endometriosis.

Endometriosis, characterized by the growth of the endometrial gland and stroma outside the uterine cavity, is a gynecological disorder affecting 6‑10% of women of reproductive age. However, the pathogenesis of endometriosis and the molecular mechanisms involved in the progression of this disease remain to be clarified. Therefore, in this study two-dimensional gel electrophoresis (2‑DE) combined with mass spectrometry (MS) were applied to explore endometrial proteins with a role in the progression of endometriosis.

Identification of biomarkers for endometriosis in eutopic endometrial cells from patients with endometriosis using a proteomics approach.

Endometriosis is a gynecological disease defined as the presence of endometrial tissue outside the uterine cavity, which is caused by various factors. Proteomic analysis of two sets of eutopic endometrial cells collected from the menstrual blood of females with (n=6; n=3) or without (n=6; n=3) endometriosis was performed to identify novel potential biomarkers for endometriosis. The data revealed that samples from endometriosis patients had stem cell characteristics, as they had higher mRNA expression levels of octamer-binding transcription factor 4 (Oct-4), C-X-C chemokine receptor type 4 (CXCR4), SRY-box containing gene 2 (SOX2) and mesenchymal-epithelial transition factor (MET) compared with that of the normal controls.

Preoperative rib cartilage imaging in 3-dimensional chest computed tomography for auricular reconstruction for microtia.

Background: There are several methods that may be used to confirm the status of rib cartilage, such as physical examinations or chest radiography, for subjects with microtia. However, these methods are limited because of clinicians' inability to gain accurate information about the rib cartilage. We performed 3-dimensional chest computed tomography to preoperatively evaluate the accuracy of rib cartilage imaging.

An evolution of communication in postoperative free flap monitoring: using a smartphone and mobile messenger application.

Unlabelled: For more precise and rapid notification of free flap status between staff members after surgery, the authors used a smartphone and mobile messenger application including multimedia during the initial postoperative period and analyzed the influence of this method for the re-exploration time and survival rate of the flap before and after use. From April of 2010 to September of 2011, 123 consecutive free flaps were reviewed. The authors increased the flap survival rate from 96.

Reliable harvesting of a large thoracodorsal artery perforator flap with emphasis on perforator number and spacing.

Background: Thoracodorsal artery perforator flaps are useful for covering extensive defects because of their generous donor-site dimensions. However, large flaps increase the risk of partial flap necrosis, and a reliable means of sizing thoracodorsal artery perforator flaps has not been devised. The authors reviewed a series of large thoracodorsal artery perforator flap transfers performed under various reconstructive conditions to evaluate surgical outcomes and placed emphasis on flap design and harvesting technique.

Interferon gamma has dual potential in inhibiting or promoting survival and growth of hematopoietic progenitors: interactions with stromal cell-derived factor 1.

We explored the possibility that interferon gamma (IFN-gamma) has bidirectional functions in the survival and growth of hematopoietic progenitors, especially with regard to interactions with stromal cell-derived factor 1 (SDF-1). IFN-gamma partially rescued normal bone marrow CD34+ cells and colony-forming cells from apoptosis induced by serum and hematopoietic growth factor (HGF) deprivation, and SDF-1 further enhanced cell survival. Short-term IFN-gamma treatment of CD34+ cells in the absence of serum and HGFs enhanced the clonal growth of the cells in synergy with SDF-1.

Overexpression of stromal cell-derived factor-1 enhances endothelium-supported transmigration, maintenance, and proliferation of hematopoietic progenitor cells.

To clarify the direct effects of aberrant overexpression of stromal cell-derived factor-1 (SDF-1) by the human endothelium on circulating progenitor cells, we overexpressed the SDF-1 gene in human umbilical vein endothelial cells using an adenoviral vector (HUVEC/AdeSDF-1) and examined the endothelium-supported trafficking and growth of hematopoietic progenitor cells (HPCs) in mobilized peripheral blood (mPB). In culture, the HUVEC/AdeSDF-1 monolayers induced the migration of mPB CD34(+) cells underneath the endothelium within a few hours, whereas HUVEC monolayers that expressed the LacZ gene (HUVEC/AdeLacZ) did not have this effect. In the Transwell system, the HUVEC/AdeSDF-1 cells supported a higher level of spontaneous transmigration of mPB CD34(+) cells than did the HUVEC/AdeLacZ cells.
