Myocardial Mass Corrected CMR Feature Tracking-Based Strain Ratios are Different in Pathologies With Increased Myocardial Mass

2020

Acute myocarditis (AM) and hypertensive heart disease (HHD) have different pathophysiological backgrounds, thus potentially showing distinct patterns of altered myocardial deformation. Therefore, CMR left ventricular (LV) feature tracking (FT)- based strain parameters were indexed to myocardial mass index (LVMi) in order to evaluate potential additional value in the differentiation among AM, HHD, and healthy volunteers (HV) compared to non-indexed conventional strain.Patients with AM (n = 43) and HHD (n = 28) underwent CMR at 3T. 61 HV served as controls. Cine imaging-based FT-strain analysis was performed and natural strain (nStrain) values were evaluated for gender and age specific differ…

Biomechanical Comparison Between Sprint Start, Sled Pulling, and Selected Squat-Type Exercises

2013

The purpose of this study was to compare kinetics, kinematics, and muscle activity among sprint start, sled pulling, and selected squat-type exercises (countermovement jumps [CMJs] and 1/2-squats with various loads) and also to examine how these exercises correlate with the performance time of the block start (10 m). Nine male athletes (4 sprinters, 3 decathlonists, 1 long jumper, and 1 triple jumper: age = 24.9 ± 3.9 years; 100-m record = 11.35 ± 0.29 seconds; track and field training years = 11.8 ± 3.1 years) volunteered as subjects. The comparisons were made with regard to the block phase (the phase of force production toward starting blocks) of the block start. In nearly all exercises, …

Outpatient endovascular aortic aneurysm repair: Experience in 100 consecutive patients

2013

OBJECTIVES:: To present the safety, feasibility, costs, and patient satisfaction of outpatient endovascular aneurysm repair (EVAR). BACKGROUND:: Our experience in more than 1000 patients indicated that in technically uncomplicated EVAR procedures, the only need for hospitalization was for access vessel complications (bleeding or occlusion) requiring secondary procedures. These complications could always be identified within the first 3 hours after EVAR. METHODS:: Two-center retrospective analysis of prospectively gathered data on 100 consecutive elective outpatient EVAR cases (Outpt EVAR). Inclusion criteria for Outpt EVAR were as follows: asymptomatic clinical state, informed consent, trav…

Epinephrine Preworkout Elevation May Offset Early Morning Melatonin Concentrations to Maintain Maximal Muscular Force and Power in Track Athletes

2014

The optimal time of day for training has become an important question for many strength and conditioning specialists, and this study was designed to add some insights into this complex question. The primary purpose of this investigation was to examine physical performance within the temporal context of the relationship between physical performance, epinephrine, and melatonin concentrations in the early morning (0530 hours) and late (1500 hours) afternoon in elite collegiate male track and field athletes (jumpers and sprinters). Subjects had a mean (±SD) age, height, and body mass of 20.4 (±1.6) years, 185.8 (±9.4) cm, and 77.9 (±8.5) kg, respectively. Blood was obtained before each AM and P…

Identification of calcium sensing receptor (CaSR) mRNA-expressing cells in normal and injured rat brain

2009

Calcium sensing receptor (CaSR), isolated for the first time from bovine and human parathyroid, is a G-protein-coupled receptors that has been involved in diverse physiological functions. At present a complete in vivo work on the identification of CaSR mRNA-expressing cells in the adult brain lacks and this investigation was undertaken in order to acquire more information on cell type expressing CaSR mRNA in the rat brain and to analyse for the first time its expression in different experimental models of brain injury. The expression of CaSR mRNAs was found mainly in scattered cells throughout almost all the brain regions. A double labeling analysis showed a colocalization of CaSR mRNA expr…

Coaches' reflections on the meaning and value of Masters athletics

2019

Masters sport is a growing social movement offering the opportunity to participate in competitive sports in later life. Although many studies have explored Masters athletes' experiences, little is known about how other actors in the sport subcultures construct meaning in Masters sport and whether their stories work to support or hinder participation. Our study explored the cultural narrative resources and life scripts surrounding sport and ageing that coaches draw upon in two European countries, England and Finland, where sport policy has put different emphasis on elite sport and sport for all. We analysed interviews from 23 athletics (track and field) coaches (8 women) to understand how th…

The influence of negative emotions on brand trust and intention to share cause-related posts: A neuroscientific study

2023

Negative user-generated content provides cues that warn other consumers to avoid using a particular product or service. This study explores whether brand feedback can counteract consumer backlash to a given company’s cause-related marketing, with a particular focus on how visual attention can moderate negative emotions. Hypotheses based on the Appraisal-Tendency Framework and commitment-trust theory were tested using neurophysiological tools (eye tracking and facial coding) and self-reported measures. The findings suggest that emotions with similar valence and arousal levels cause differing trust perceptions and consumer behavioral responses (sharing intentions), based on the presence or ab…

Elapsed time on first buying triggers brand choices within a category: A virtual reality-based study

2016

This study integrates neuroscientific tools such as data from eye movements, store navigation, and brand choice in a virtual supermarket into a single source data analysis to examine consumer choice, customer experience, and shopping behavior in a store. Through qualitative comparative analysis, the findings suggest that a high level of attention to a brand and slow eye movements between brands lead to additional brand purchases within the product category. This study points out that the key driver of additional brand choices is the time buyers spend on the first choice, showing that the allocation of less for the first choice triggers additional purchases Within the product category and, t…
