Published: May 2016

AimsUrine proteome analysis (UPA) has already provided accurate discriminatory patterns of urinary peptides for renal disease, coronary artery disease, and asymptomatic LV diastolic dysfunction. UPA has now been used to characterize a discriminatory peptide biomarker pattern and establish a diagnostic classifier for heart failure patients with reduced ejection fraction (HFrEF) in the presence of chronic kidney disease (CKD).Methods and resultsWe analysed the urine proteome profiles obtained by capillary electrophoresis online coupled to micro‐TOF (time of flight) mass spectrometry of 126 individuals, 59 HFrEF patients and 67 controls matched for age, sex, and renal function. In total, 107 significant discriminatory peptides were identified and used to establish a support vector machine‐based classifier that was successfully applied to a test set of 25 HFrEF patients and 33 controls, achieving 84% sensitivity and 91% specificity. The majority of sequenced peptides were fragments of collagen type I and III.ConclusionUPA was able to identify a set of HFrEF‐specific urinary peptide biomarkers on a background of CKD that were successfully utilized to establish a syndrome's classifier.
Discussion of ‘Modelling viscous damping in nonlinear response history analysis of buildings for earthquake excitation’ by Anil K. Chopra and Frank McKenna
Authors: Hall John F. 
Published: May 2016

SummaryThis discussion deals with recommendations in the paper on appropriate damping formulations for use in nonlinear response history analysis of buildings. Concern over potentially excessive damping forces and moments should extend beyond the damping moments produced by the stiffness proportional part of Rayleigh damping that corresponds to rotational springs used to explicitly model plastic hinges. The key to an appropriate damping formulation for nonlinear analysis is a realistic mechanism that allows all damping forces and moments to be meaningfully assessed. Then features can be added to keep these forces and moments within reasonable bounds. Copyright © 2016 John Wiley & Sons, Ltd.
In vivo correlates of thermoregulatory defense in humans: Temporal course of sub‐cortical and cortical responses assessed with fMRI
Authors: Muzik Otto , Diwadkar Vaibhav A. 
Published: May 2016

AbstractExtensive studies in rodents have established the role of neural pathways that are activated during thermoregulation. However, few studies have been conducted in humans to assess the complex, hierarchically organized thermoregulatory network in the CNS that maintains thermal homeostasis, especially as it pertains to cold exposure. To study the human thermoregulatory network during whole body cold exposure, we have used functional MRI to characterize changes in the BOLD signal within the constituents of the thermoregulatory network in 20 young adult controls during non‐noxious cooling and rewarming of the skin by a water‐perfused body suit. Our results indicate significant decreases of BOLD signal during innocuous whole body cooling stimuli in the midbrain, the right anterior insula, the right anterior cingulate, and the right inferior parietal lobe. Whereas brain activation in these areas decreased during cold exposure, brain activation increased significantly in the bilateral orbitofrontal cortex during this period. The BOLD signal time series derived from significant activation sites in the orbitofrontal cortex showed opposed phase to those observed in the other brain regions, suggesting complementary processing mechanisms during mild hypothermia. The significance of our findings lies in the recognition that whole body cooling evokes a response in a hierarchically organized thermoregulatory network that distinguishes between cold and warm stimuli. This network seems to generate a highly resolved interoceptive representation of the body's condition that provides input to the orbitofrontal cortex, where higher‐order integration takes place and invests internal states with emotional significance that motivate behavior.

Seasonal changes in hepatocytic lipid droplets, glycogen deposits, and rough endoplasmic reticulum along the natural breeding cycle of female ohrid trout (Salmo letnica Kar.)—A semiquantitative ultrastructural study
Authors: Jordanova Maja , Rebok Katerina , Malhão Fernanda , Rocha Maria J. , Rocha Eduardo 
Published: May 2016

ABSTRACTThis study on wild female Ohrid trout was primarily designed to provide a general overview of the breeding cycle influence upon selected aspects of hepatocytes. According with a semiquantitatively evaluation, some of these cell's structural compartments change during the breeding cycle. Structural modifications were disclosed in the relative occurrence of lipid, glycogen, and RER content during breeding cycle. The relative amount of lipid deposits in the hepatocytes was much greater in previtellogenesis, and decreased postspawning. So, while the seasonal changes in RER were positively related with the ovary maturation status, those of the lipid droplets followed an opposite trend. The hepatocytic glycogen occurred rarely, mainly in late‐vitellogenesis and spawning, suggesting that in this species such kind of energy storage is comparatively unimportant. Lipid accumulation and later usage is, probably, the relevant biochemical pathway for Ohrid trout in the wild. While glycogen and RER contents were positively correlated with the gonadosomatic index, lipids were negatively correlated. Additionally, glycogen inclusions were positively correlated with the plasma estradiol levels. When comparing seasonal patterns from wild Ohrid trout with those from well‐studied rainbow and brown trout (specimens studied were from aquaculture), there are contradicting results as to lipid and glycogen reserves, and also as to RER loads. The differences among the mentioned trout can result from intrinsic interspecies differences or may be associated with natural feeding conditions versus feeding with commercially prepared diets, or other factors. This study offers new data useful as standard to access liver pathology in wild and aquacultured Ohrid trout. Microsc. Res. Tech. 79:700–706, 2016. © 2016 Wiley Periodicals, Inc.
Chelation‐Induced Polymer Structural Hierarchy/Complexity in Water
Authors: Han Jie , Zhou Kaiyi , Zhu Xuechao , Yu Qiuping , Ding Yi , Lu Xinhua , Cai Yuanli 
Published: May 2016

Understanding nanoscale structural hierarchy/complexity of hydrophilic flexible polymers is imperative because it can be viewed as an analogue to protein‐alike superstructures. However, current understanding is still in infancy. Herein the first demonstration of nanoscale structural hierarchy/complexity via copper chelation–induced self‐assembly (CCISA) is presented. Hierarchically‐ordered colloidal networks and disks can be achieved by deliberate control of spacer length and solution pH. Dynamic light scattering, transmission electron microscopy, and atomic force microscopy demonstrate that CCISA underwent supramolecular‐to‐supracolloidal stepwise‐growth mechanism, and underline amazing prospects to the hierarchically‐ordered superstructures of hydrophilic flexible polymers in water.

Published: May 2016

AbstractObjectiveTo investigate the clinical value of chromosomal microarray analysis (CMA) in the prenatal diagnosis of chromosomal abnormalities in fetal growth restriction (FGR) cases.MethodThe ultrasound findings of 107 FGR cases subjected to invasive prenatal diagnostic testing from March 2013 to October 2015 were retrospectively reviewed. Karyotyping was performed in all cases, and CMA was performed in 80 cases.ResultsIn our study, karyotype analysis identified chromosomal aberrations in 9.3% (10/107) of the cases, while CMA detected abnormalities in 18.8% (15/80) of the cases. CMA achieved a 11.4% detection rate of chromosomal abnormalities among FGR cases with a normal karyotype. Among 53 FGR cases without malformations, CMA increased (9.4%; 95%CI, 1.6%–17.3%) the detection rate of chromosomal abnormalities. CMA identified more chromosomal abnormalities (50.0%; 95%CI, 19.0%–81.0%) than karyotyping (30.0%; 95%CI, 7.0%–65.0%) among the cases diagnosed during the second trimester. Further, the detection rate in cases with asymmetric FGR was higher with CMA (33.3%; 95%CI, 10.0%–65.0%) than with karyotyping (16.7 %; 95%CI, 2.0%–48.0%).ConclusionOur study highlights the added value of CMA compared with karyotyping in evaluation of asymmetric FGR cases diagnosed during the second trimester without sonographic anomalies. © 2016 John Wiley & Sons, Ltd.

SUMMARYThessaly, Central Greece, is an endemic area for leishmaniasis with higher incidence rate during the last years. We herein investigated the geographical distribution of human leishmaniasis cases and Leishmania infected dogs in relation to environmental parameters to identify high-risk areas. All the human leishmaniasis cases (n = 82) reported to Hellenic Centre for Disease Control and Prevention from 2007 to 2014 and 85 Leishmania polymerase chain reaction positive dogs were included in this study. To analyse the data geographical information system (GIS) together with the Ecological Niche Model (ENM) were used. The most important findings of the study were: (i) Central plain of Thessaly together with the coast line and the western and eastern lowlands were identified as high-risk geographical areas. (ii) The highest percentage of the high-risk areas was found in low altitude (<200 m above sea level) and in irrigated and cultivated agricultural areas. (iii) A total of 20% of the human settlements was found in high-risk areas. (iv) The maximum temperature of the warmest month contributes the highest per cent to define both environmental niche profiles for humans and dogs. (v) The ENM could be a useful tool for the epidemiological study of leishmaniasis. Spatial analysis may allow the design of entomological studies and identify target population in order to implement preventive measures.
