Abstract
Breast cancer is genetically and clinically heterogeneous. Triple negative breast cancer (TNBC) is a subtype of breast cancer that is usually associated with poor outcome and lack of benefit from targeted therapy. We used microarray analysis to perform a pathway analysis of TNBC compared with non-triple negative breast cancer (non-TNBC). Overexpression of several Wnt pathway genes, such as frizzled homolog 7 (FZD7), low density lipoprotein receptor-related protein 6 and transcription factor 7 (TCF7) was observed in TNBC, and we directed our focus to the Wnt pathway receptor, FZD7. To validate the function of FZD7, FZD7shRNA was used to knock down FZD7 expression. Notably, reduced cell proliferation and suppressed invasiveness and colony formation were observed in TNBC MDA-MB-231 and BT-20 cells. Study of the possible mechanism indicated that these effects occurred through silencing of the canonical Wnt signaling pathway, as evidenced by loss of nuclear accumulation of β-catenin and decreased transcriptional activity of TCF7. In vivo studies revealed that FZD7shRNA significantly suppressed tumor formation, through reduced cell proliferation, in mice bearing xenografts without FZD7 expression. Our findings suggest that FZD7-involved canonical Wnt signaling pathway is essential for tumorigenesis of TNBC, and thus, FZD7 shows promise as a biomarker and a potential therapeutic target for TNBC.

Abstract
The laparoscopic approach to donor nephrectomy is becoming increasingly common. While it is felt that the recovery from laparoscopic nephrectomy is quicker and less painful, a number of complications have been reported. A rarely reported on complication in the literature with significant morbidity is ipsilateral orchalgia. From 1998 to 2008, 257 hand-assisted laparoscopic donor nephrectomies were performed at our institution. Eight of 129 (6.2%) men complained of de novo ipsilateral orchalgia postoperatively. The average duration of pain was 402 days. Patients reported significant morbidity related to this complication. None, however, required further treatment. Three patients reported that they would reconsider organ donation as a result of testicular pain. Our technique originally included dissection and ligation of the gonadal vein en bloc with the ureter at the level of the left common iliac artery. Since recognizing this complication, we have adopted a gonadal vein sparing approach so as not to disturb the vessel below its point of ligation at the renal vein. To date, 50 patients have undergone the modified technique without experiencing orchalgia. In conclusion, ipsilateral testicular pan is a relatively frequent complication of laparoscopic donor nephrectomy and may be a source of significant morbidity. Using a modified surgical technique, this complication can be reduced or eradicated.

Abstract
The aim of this study was to retrospectively review our experience of performing simultaneous operations on concomitant diseases in the esophagus and lungs. From January 1998 to July 2009, simultaneous operations were performed on 13 patients with concomitant esophageal and pulmonary diseases, using coordinated surgical approaches. Among the 13 patients, six had primary cancers in the esophagus and lungs, five had primary esophageal cancer accompanied by a benign pulmonary disease, one had benign diseases in both esophagus and lung, and one had primary esophageal cancer with metastasis to the left lower lung. All patients survived the operations. Two major complications occurred postoperatively. One complication was bronchopleural fistula and the other was intrathoracic gastric laceration. Both patients recovered after additional treatments. Simultaneous operation of concomitant diseases in the esophagus and lungs is feasible and safe in selected patients who have received careful preoperative assessment, well-designed surgical approach, and proper perioperative management.

Abstract
To normalize a set of quantitative real-time PCR (q-PCR) data, it is essential to determine an optimal number/set of housekeeping genes, as the abundance of housekeeping genes can vary across tissues or cells during different developmental stages, or even under certain environmental conditions. In this study, of the 20 commonly used endogenous control genes, 13, 18 and 17 genes exhibited credible stability in 56 different tissues, 10 types of adipose tissue and five types of muscle tissue, respectively. Our analysis clearly showed that three optimal housekeeping genes are adequate for an accurate normalization, which correlated well with the theoretical optimal number (r ≥ 0.94). In terms of economical and experimental feasibility, we recommend the use of the three most stable housekeeping genes for calculating the normalization factor. Based on our results, the three most stable housekeeping genes in all analysed samples (TOP2B, HSPCB and YWHAZ) are recommended for accurate normalization of q-PCR data. We also suggest that two different sets of housekeeping genes are appropriate for 10 types of adipose tissue (the HSPCB, ALDOA and GAPDH genes) and five types of muscle tissue (the TOP2B, HSPCB and YWHAZ genes), respectively. Our report will serve as a valuable reference for other studies aimed at measuring tissue-specific mRNA abundance in porcine samples.

Abstract
Skeletal muscle denervation eventually causes atrophy as a result of interrupted nerve conduction and the lack of nutritional factors. Myogenin is a myogenic regulatory factor that plays a key role in myoblast differentiation. Changes in myogenin expression in denervated rat skeletal muscle have been demonstrated, but myogenin expression in denervated human skeletal muscle has not been reported. Human muscle samples were analysed at different time-points post-denervation to evaluate changes in myogenin expression and their relationship with skeletal muscle atrophy. Post-denervation, myogenin mRNA levels peaked at 7 months and were 37.5 times the normal level. Expression levels then declined to 21 and 11 times the normal level at 12 and 26 months post-denervation, respectively. Prolonged denervation resulted in pathological changes characterized by decreased numbers of intact muscle fibres.

Abstract
AIMS To evaluate how to most efficiently screen populations to detect people at high risk of incident Type 2 diabetes and those with prevalent, but undiagnosed, Type 2 diabetes. METHODS Data from 5814 adults in the Australian Diabetes, Obesity and Lifestyle study were used to examine four different types of screening strategies. The strategies incorporated various combinations of cut-points of fasting plasma glucose, the non-invasive Australian Type 2 Diabetes Risk Assessment Tool (AUSDRISK1) and a modified version of the tool incorporating fasting plasma glucose (AUSDRISK2). Sensitivity, specificity, positive predictive value, screening costs per case of incident or prevalent undiagnosed diabetes identified and intervention costs per case of diabetes prevented or reverted were compared. RESULTS Of the four strategies that maximized sensitivity and specificity, use of the non-invasive AUSDRISK1, followed by AUSDRISK2 in those found to be at increased risk on AUSDRISK1, had the highest sensitivity (80.3%; 95% confidence interval 76.6-84.1%), specificity (78.1%; 95% confidence interval 76.9-79.2%) and positive predictive value (22.3%; 95% confidence interval 20.2-24.4%) for identifying people with either prevalent undiagnosed diabetes or future incident diabetes. It required the fewest people (24.1%; 95% confidence interval 23.0-25.2%) to enter lifestyle modification programmes, and also had the lowest intervention costs and combined costs of running screening and intervention programmes per case of diabetes prevented or reverted. CONCLUSIONS Using a self-assessed diabetes risk score as an initial screening step, followed by a second risk score incorporating fasting plasma glucose, would maximize efficiency of identifying people with undiagnosed Type 2 diabetes and those at high risk of future diabetes.

Abstract
Association of the IVS1 -27G/A polymorphism of Krüppel-like factor 6 (KLF6) with gastric cancer was examined in a Chinese population comprising 300 gastric cancer patients and 300 healthy controls. Single-nucleotide polymorphism analysis was performed by amplifying intron 1 of KLF6 and sequencing the products. The KLF6 genotype IVS1 -27AA was significantly less frequent in gastric cancer patients than in controls and significantly less frequent in patients with advanced (stage III/IV) gastric cancer than in those with early (stage I/II) cancer. Stratification by location, Lauren's classification and histological differentiation revealed no significant differences in genotype distribution. Thus, in this Chinese population the KLF6 IVS1 -27AA genotype was associated with a decreased risk of gastric cancer and with cancer stage. Further study is required to clarify the mechanisms involved and, potentially, to facilitate the design of effective clinical trials.

Abstract
We demonstrate irreversible continuous filament formation when a weak laser focus is positioned near the edge of an evaporating colloidal droplet containing carbon and gold nanoparticles. Optical trapping, hydrothermal, and chemical interactions lead to controlled colloidal synthesis of stable, irreversible mesoscale filaments of arbitrary shape and size. Mechanisms for this optically directed assembly are discussed with fluid dynamics, molecular dynamics, and lattice kinetic Monte Carlo calculations.
