Abstract
Background Patients undergoing percutaneous coronary intervention (PCI) may experience rapid atherosclerotic plaque progression in nontreated vessels that is unlikely to result from natural de novo atherosclerosis. We hypothesize that intra-lesion bleeding plays a central role in this process. The aim of this study is to investigate the factors that may contribute to accelerated narrowing in coronary diameter. Methods We reviewed 65 interventional procedures and their consequent staged PCIs and mapped the coronary tree into 16 segments (as divided by the American Heart Association), grading the percentage of stenosis in each segment and spotting the rapidly progressing lesions. Demographic, procedural, and laboratory data were recorded and analyzed. Results For the lesions that progressed rapidly in the time period between angiographies, the administration of eptifibatide intra-procedurally was associated with rapid progression of coronary lesions. Moreover, an increased white blood cell count prior to the index procedure was also associated with a trend toward rapid plaque progression. Conclusions In this hypothesis-generating study, treatment with a IIb/IIIa inhibitor in the index PCI was associated with an accelerated short-term progression of some of the nontreated lesions, suggesting that this mode of anti-aggregation therapy could facilitate plaque hemorrhage and consequent acceleration of coronary atherosclerosis in eroded plaques.

Abstract
Aortic perforation is a rare complication of transcatheter aortic valve replacement associated with grim outcomes. Tortuous and calcified aortas increase the risk of aortic trauma and perforation. We report a case in which, despite massive thoracic bleeding, avoidance of thoracic aortic surgery resulted in clinical recovery. (Level of Difficulty: Intermediate.).

Abstract
AIM To evaluate insufficient rotational movement of the left ventricle (LV) as a potential novel mechanism for functional regurgitation of the mitral valve (FMR). METHODS AND RESULTS We compared reference subjects and patients with LV dysfunction (LVD, ejection fraction EF < 50%) with and without FMR (regurgitant volume RVol>10 ml). Subjects without structural mitral valve pathology undergoing cardiac MRI were evaluated. Delayed enhancement, global LV remodeling parameters, systolic twist and torsion were measured (using manual and novel automated cardiac MRI tissue-tracking). The study included 117 subjects with mean ± SD age 50.4 ± 17.8 years, of which 30.8% were female. Compared to subjects with LVD without FMR (n = 31), those with FMR (n = 37) had similar clinical characteristics, diagnoses, delayed enhancement, EF, and longitudinal strain. Subjects with FMR had significantly larger left ventricles (EDVi:136.6 ± 41.8 vs 97.5 ± 26.2 ml/m, p < 0.0001) with wider separation between papillary muscles (21.1 ± 7.6 vs 17.2 ± 5.7 mm, p = 0.023). Notably, they had lower apical (p < 0.0001) but not basal rotation and lower peak systolic twist (3.1 ± 2.4° vs 5.5 ± 2.5°, p < 0.0001) and torsion (0.56 ± 0.38°/cm vs 0.88 ± 0.52°/cm, p = 0.004). In a multivariate model for RVol including age, gender, twist, LV end-diastolic volume, sphericity index and separation between papillary muscles, only gender, volume and twist were significant. Twist was the most powerful correlate (beta -2.23, CI -3.26 to -1.23 p < 0.001). In patients with FMR, peak systolic twist negatively correlates with RVol (r = -0.73, p < 0.0001). CONCLUSION Reduced rotational systolic LV motion is significantly and independently associated with RVol among patients with FMR, suggesting a novel pathophysiological mechanism and a potential therapeutic target.

Abstract
We demonstrate a novel array-based diagnostic platform comprising lipid/polydiacetylene (PDA) vesicles embedded within a transparent silica-gel matrix. The diagnostic scheme is based upon the unique chromatic properties of PDA, which undergoes blue-red transformations induced by interactions with amphiphilic or membrane-active analytes. We show that constructing a gel matrix array hosting PDA vesicles with different lipid compositions and applying to blood plasma obtained from healthy individuals and from patients suffering from disease, respectively, allow distinguishing among the disease conditions through application of a simple machine-learning algorithm, using the colorimetric response of the lipid/PDA/gel matrix as the input. Importantly, the new colorimetric diagnostic approach does not require a priori knowledge on the exact metabolite compositions of the blood plasma, since the concept relies only on identifying statistically significant changes in overall disease-induced chromatic response. The chromatic lipid/PDA/gel array-based "fingerprinting" concept is generic, easy to apply, and could be implemented for varied diagnostic and screening applications.

Abstract
Finding new peptide biomarkers for stomach cancer in human sera that can be implemented into a clinically practicable prediction method for monitoring of stomach cancer. We studied the serum peptidome from two different biorepositories. We first employed a C8-reverse phase liquid chromatography approach for sample purification, followed by mass-spectrometry analysis. These were applied onto serum samples from cancer-free controls and stomach cancer patients at various clinical stages. We then created a bioinformatics analysis pipeline and identified peptide signature discriminating stomach adenocarcinoma patients from cancer-free controls. Matrix Assisted Laser Desorption/Ionization–Time of Flight (MALDI-TOF) results from 103 samples revealed 9 signature peptides; with prediction accuracy of 89% in the training set and 88% in the validation set. Three of the discriminating peptides discovered were fragments of Apolipoproteins C-I and C-III (apoC-I and C-III); we further quantified their serum levels, as well as CA19-9 and CRP, employing quantitative commercial-clinical assays in 142 samples. ApoC-I and apoC-III quantitative results correlated with the MS results. We then employed apoB-100-normalized apoC-I and apoC-III, CA19-9 and CRP levels to generate rules set for stomach cancer prediction. For training, we used sera from one repository, and for validation, we used sera from the second repository. Prediction accuracies of 88.4% and 74.4% were obtained in the training and validation sets, respectively. Serum levels of apoC-I and apoC-III combined with other clinical parameters can serve as a basis for the formulation of a diagnostic score for stomach cancer patients.

Abstract
A new design DNA sequencing electrophoresis device is described. The device, called the ribbon channeled plate rotating drum (rprd), consists of two major components, the plate assembly and the drum assembly. The plate assembly contains a machined or etched plate of individual micro-channels called the ribbon channeled plate. The ribbon channeled plate and other components of the plate assembly combine the advantages of thin gels and capillary arrays in a single unit with few of the disadvantages. The other major component of rprd is the drum assembly, which facilitates direct blotting onto deposition membranes affixed to a large plastic drum. The drum with attached membrane and deposited electrophoretically resolved ladders is easily moved to special units facilitating downstream processing and detection. The drum unit, although versatile, is specifically designed to be used with multiplex sequencing.

Abstract
DNA SIMDEX is a DOS-based computer program designed to assist in the visual scoring of DNA fingerprint assays. DNA SIMDEX uses the migration distances of the individual DNA bands to generate lists of probable matching and nonmatching bands and automatically calculates a probable similarity index between DNA fingerprints based on these initial predictions. After comparisons are edited by the user, the final similarity index, along with accompanying data, can be saved on a floppy disk or hard drive for easy storage and retrieval or can be printed directly on a laser or line printer. The program has been developed to function with or without an image-analysis system, thus making it an inexpensive alternative for small laboratories.
