Quantitative trait loci analysis of morphological traits in Citrus
Mehtap S¸ ahin-C¸ evik,Gloria A. Moore 한국식물생명공학회 2012 Plant biotechnology reports Vol.6 No.1
The objectives of this study were to understand the genetic basis of morphological variation observed in the genus Citrus and its relatives and to identify genomic regions associated with certain morphological traits using genetic linkage mapping and quantitative trait loci (QTLs) analysis with random amplified polymorphic DNA (RAPD) markers. First, a genetic linkage map was constructed with RAPD markers obtained by screening 98 progeny plants from a {Citrus grandis 9 [C. paradisi 9 Poncirus trifoliata]} 9 {[(C. paradisi 9 P. trifoliata) 9 C. reticulata] 9 [(C. paradisi 9 Poncirus trifoliata) 9 C. sinensis]} intergeneric cross. The map contains 69 RAPD markers distributed into nine linkage groups. Then, 17 different morphological traits, including six tree and two leaf characters of 98 progeny plants and six floral and three fruit characters of about half of the same progeny plants were evaluated for 2 years and statistically analyzed for variation. Statistical analysis of individual traits indicated that trunk diameter and growth, tree height, canopy width, tree vigor and growth, leaf length and width, petal and anther numbers, petal length and width, length of pistil and style, fruit length and diameter, and fruit segment number showed normal or close to normal distribution, suggesting that these traits may be inherited quantitatively. Quantitative data from the morphological traits were analyzed to detect markers and putative QTLs associated with these traits using interval mapping method. QTL analysis revealed 18 putative QTLs of LOD[3.0 associated with 13 of the morphological traits analyzed. The putative QTLs were distributed in several different linkage groups, and QTLs associated with similar traits were mostly mapped to the same LG or similar locations in the linkage group, indicating that the same genomic region is involved in the inheritance of some of the morphological traits.

Homology of contact CR-warped product submanifolds of an odd-dimensional unit sphere
Bayram \c{S}ahin,Fulya \c{S}ahin 대한수학회 2015 대한수학회보 Vol.52 No.1
We show that homology group on a contact CR-warped product submanifold in odd dimensional sphere is zero under certain conditions in terms of warping function and the dimension of the submanifold.

Percutaneous device closure of atrial septal defect (ASD) is an alternative treatment to surgery. The main advantages of the percutaneous approach include avoidance of surgery, short procedure time and hospital length, in addition to comparable rates of complications. However,percutaneous device closure is associated with infrequent early and late complications including device embolization, air embolism,cardiac tamponade and thrombotic complications. We report a rare complication of silent and late device embolization of the ASD occluder device into the right pulmonary artery, three months after implantation.

Background and Objectives: Left ventricular hypertrophy (LVH), a sign of subclinical cardiovascular disease, is an important predictor of cardiovascular morbidity and mortality. The aim of our study was to determine the association of left ventricular mass (LVM) with possible causative anthropometric and biochemical parameters as well as carotid intima-media thickness (CIMT) and brachial flow-mediated dilation (FMD) as surrogates of atherosclerosis and endothelial dysfunction, respectively, in previously untreated hypertensive patients. Subjects and Methods: Our study included 114 consecutive previously untreated hypertensive patients who underwent echocardiography and ultrasonography to evaluate their vascular status and function via brachial artery CIMT and FMD. Results: Among all study parameters, age, systolic blood pressure (BP), diastolic BP, pulse pressure, plasma glucose, uric acid, total bilirubin, direct bilirubin, hemoglobin, and CIMT were positively correlated with the LVM index. Multiple logistic regression analysis revealed that office systolic BP, age, male gender, and total bilirubin were independent predictors of LVH. Conclusion: Bilirubin seems to be related to LVM and LVH. The positive association of bilirubin with these parameters is novel and requires further research.

Purpose: The study aimed to examine the efficacy of the I.V. House UltraDressing for protecting peripheral intravenous catheters (PIVCs) in pediatric patients. Methods: This randomized controlled trial comprised 60 pediatric patients (aged 2e24 months): 30 in the experimental group and 30 in the control group. The PIVC dwell time and phlebitis scores were also reported for both groups. The degree of phlebitis was determined using the Visual Infusion Phlebitis Scale (VIPS) and was recorded every 8 hours from the start of antibiotic therapy until catheter removal. Results: The mean catheter dwell time in the experimental group (2.10 ± 1.55 days) was significantly longer than that in the control group (1.27 ± 0.45 days) (p < .01). However, there were no significant differences between the scores and signs of phlebitis in both groups (p > .05). Conclusion: The I.V. House UltraDressing is a useful device that can be used to increase catheter dwell time and protect and stabilize PIVCs in pediatric patients.
