Leave-one-out Cross Validation (LOO-CV) gives an almost unbiased estimate of the expected generalization error. But the LOO-CV classical procedure with Support Vector Machines (SVM) is very expensive and cannot be applied when training set has more that few hundred examples. We propose a new LOO-CV method which uses modified initialization of Sequential Minimal Optimization (SMO) algorithm for ...

Triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio, an indicator of atherogenic dyslipidemia, is a predictor of cardiovascular (CV) outcomes in the general population and has been correlated with atherosclerotic events. Whether the TG/HDL-C ratio can predict CV outcomes and survival in dialysis patients is unknown. We performed this prospective, observational cohort study and...

BACKGROUND A pre-specified meta-analysis of cardiovascular (CV) events from 21 phase 2b/3 dapagliflozin clinical trials was undertaken to characterise the CV profile of dapagliflozin. This showed no increase in CV risk with dapagliflozin compared with control (placebo or comparator treatment) with or without background glucose-lowering therapies. The analysis reported here aimed to characterise...

We read with interest the paper of Marshall et al entitled 'Direct visualisation of collateral ventilation in COPD with hyper-polarised gas MRI'. 1 Collateral ventilation (CV) is defined as 'the ventilation of alveolar structures through passages that bypass the normal airway'. 2 This happens through the intra-alveolar pores of Kohn, the bronchio-loalveolar communications of Lambert and the int...

To clarify the chronologic genetic diversity of coxsackievirus A16 (CV-A16) strains associated with hand, foot, and mouth disease (HFMD) epidemics in a restricted area and their genetic relation with those isolated in other areas, we investigated the genetic diversity of the 129 CV-A16 strains associated with HFMD epidemics in Fukushima, Japan, from 1983 to 2003, and compared their genetic rela...

Traditional cardiovascular risk (CV) factors based on the Framingham study have been used to estimate the risk of CV events and determine target cholesterol levels for primary prevention. Recently published systematic reviews have, however, demonstrated that the Framingham risk score is limited in certain cohorts and requires adjustment. Indeed, traditional CV risk factors fail to predict the d...

BACKGROUND Patients with chronic kidney disease (CKD) are associated with increased cardiovascular (CV) morbidity and mortality. Echocardiographic measures of heart structure and function have been reported to predict adverse CV outcomes in various pathologic conditions. The aim of this study is to assess whether echocardiographic parameters are independently associated with increased CV events...

The iron-storage protein ferritin was found to be associated with highly purified coated vesicles (CV) from chicken liver. Chicken liver ferritin was morphologically similar to ferritin from horse spleen and could be isolated using a specific anti-ferritin monoclonal antibody. This antibody recognized a 240 X 10(3) Mr form of chicken ferritin but not the 22 X 10(3) Mr ferritin subunit after pro...

Left ventricular (LV) function is generally assessed independent of structural remodeling and vice versa. The purpose of this study was to evaluate a novel LV global function index (LVGFI) that integrates LV structure with global function and to assess its predictive value for cardiovascular (CV) events throughout adult life in a multiethnic population of men and women without history of CV dis...

AIMS Circulating progenitor cells are believed to participate in cardiovascular (CV) homeostasis and their exhaustion has been linked to CV damage. As general agreement on their characterization is lacking, this work was carried out to assess the relationships between different antigenic profiles of progenitor cells and CV risk, with special regard to metabolic syndrome (MetSyn). METHODS AND ...
