Xylophagous leafhoppers are vectors of xylem-limited plant pathogens such as citrus variegated chlorosis (CVC) and Pierce's disease, which cause Xylella diseases. Currently, no cure for Xylella diseases exists. The objective of endosymbiont control using Wolbachia pipientis is to reduce the populations of insect vectors,potentially preventing the expansion of Xylella diseases. The purpose of this study was to establish primary cell cultures from adult xylem-feeding leafhoppers to study Wolbachia biology. Cells from adult male and female Kolla paulula (Walker) (Hemiptera: Membracoidea: Cicadellinae) were successfully cultured in Dulbecco's Modified Eagle Medium containing 20% fetal bovine serum and were maintained for more than 6 months. Cells of both male and female adults are round and semi-attached. The doubling times for male and female K. paulula cells are approximately 8 and 10 days, respectively. The presence of Wolbachia in K. paulula cell cultures was detected by polymerase chain reaction (PCR) amplification of Wolbachia surface protein (wsp) gene. The cell cultures developed in this study may be useful in studying interactions between Wolbachia and its hosts of different genders.

Ideal Topographic Simulations for Null Measurement Data
Yan-Jen Su,Chi-Hong Tung,Leh-Rong Chang,Jin-Liang Chen,Calvin Chang 한국정밀공학회 2008 International Journal of Precision Engineering and Vol.9 No.4
A method is described for ideally reconstructing the profile from a surface profiling measurement containing a reasonable amount of null measurement data. The proposed method can conjecture lost information and rectify irregular data that result due to bad measuring environments. signal transmission noise. or instrument-induced errors. The method adopts the concept 0/ computer graphics and consists of several processing steps. First, a search for valid data in the neighborhood of the null data is performed. The valid data are then grouped and their contours are extracted. By analyzing these contours, a bounding box can be obtained and the general distribution of the entire area encompassing the valid and null data is determined. Finally, em ideal surface model is overlaid onto the measurement results based on the bounding box, generating a complete reconstruction of the calculations. A surface-profiling task on a liquid crystal display photo spacer is used to verify the proposed method. The results are compared to those obtained through the use of a scanning electron microscope to demonstrate the accuracy of the proposed method.

Background and Objectives: The aim of this study was to identify clinical, lesional, and procedural predictors for adverse outcomes of coronary angioplasty and stenting in coronary bypass candidates. Subjects and Methods: This cohort study included 107 consecutive candidates for coronary artery bypass surgery who underwent percutaneous coronary intervention with multiple coronary stents between Jan 2004 and Dec 2011. The study endpoint was major adverse cardiovascular events (MACEs) including all-cause mortality, nonfatal myocardial infarction, repeat revascularization, and stent thrombosis. Follow up was from the date of index percutaneous coronary intervention to the date of the first MACE, date of death, or December 31, 2015, whichever came first. Results: In this study (age 62.3±11.2 years, 86% male), 38 patients (36%) had MACE. Among baseline, angiographic, and procedural parameters, there were significant differences in lower left ventricular ejection fraction (LVEF) and worse renal function. In a Cox regression model, LVEF and chronic kidney disease (CKD) were significant predictors for MACE. After a multivariate adjustment, CKD remained a significant predictor of MACEs (hazard ratio: 2.97, 95% confidence interval: 1.50-5.90). Conclusions: For coronary bypass candidates who were treated with coronary angioplasty and stenting, CKD seems to be the strongest predictor for adverse outcomes compared with other traditional factors.

The development of Taiwan Fracture Liaison Service network

Osteoporosis and its associated fragility fractures are becoming a severe burden in the healthcare system globally. In the Asian-Pacific (AP) region, the rapidly increasing in aging population is the main reason accounting for the burden. Moreover, the paucity of quality care for osteoporosis continues to be an ongoing challenge. The Fracture Liaison Service (FLS) is a program promoted by International Osteoporosis Foundation (IOF) with a goal to improve quality of postfracture care and prevention of secondary fractures. In this review article, we would like to introduce the Taiwan FLS network. The first 2 programs were initiated in 2014 at the National Taiwan University Hospital and its affiliated Bei-Hu branch. Since then, the Taiwan FLS program has continued to grow exponentially. Through FLS workshops promoted by the Taiwanese Osteoporosis Association (TOA), program mentors have been able to share their valuable knowledge and clinical experience in order to promote establishments of additional programs. With 22 FLS sites including 11 successfully accredited on the best practice map, Taiwan remains as one of the highest FLS coverage countries in the AP region, and was also granted the IOF Best Secondary Fracture Prevention Promotion award in 2017. Despite challenges faced by the TOA, we strive to promote more FLS sites in Taiwan with a main goal of ameliorating further health burden in managing osteoporotic patients.
