Muscle fiber-type distribution predicts weight gain and unfavourable left ventricular geometry: a 19 year follow-up study

2006

BACKGROUND: Skeletal muscle consists of type-I (slow-twitch) and type-II (fast-twitch) fibers, with proportions highly variable between individuals and mostly determined by genetic factors. Cross-sectional studies have associated low percentage of type-I fibers (type-I%) with many cardiovascular risk factors. METHODS: We investigated whether baseline type-I% predicts left ventricular (LV) structure and function at 19-year follow-up, and if so, which are the strongest mediating factors. At baseline in 1984 muscle fiber-type distribution (by actomyosin ATPase staining) was studied in 63 healthy men (aged 32–58 years). The follow-up in 2003 included echocardiography, measurement of obesity rel…

Sleep-disordered breathing in the elderly

2009

Purpose: The prevalence of sleep-disordered breathing (SDB) increases with aging. SDB is a risk of hypertension, and both might lead to cognitive decline. However, the role of SDB and hypertension on the pathogenesis of age-related cognitive decline remains unclear. We examined the effects of these two diseases on cognitive function in elderly adults.

Taking the acid test: Mediterranean limpets face up to climate change

2014

Impacts of climate change involve the interactions of multiple stressors on intertidal organisms, but rarely are the impacts of these stressors examined together. Many tests are also conducted in artificial, controlled laboratory conditions, without making use of natural opportunities to test performance of organisms under different environmental stressors. Given its small tidal range, the Mediterranean Sea provides such an opportunity, with a very fine scale environmental gradient and species living very close to each other over the tidal gradient. The vertical distribution of the limpets, Patella rustica and P. caerulea overlap in Palermo, Sicily, but despite this they have different ther…

Ski economy and physiological responses while double poling : curved vs. straight poles

2015

Christina Mishica (2015). Ski economy and physiological responses while double poling: curved vs. straight poles. Department of Biology of Physical Activity, University of Jyväskylä, Master’s Thesis in Exercise Physiology. 57 pp. Introduction. Double poling (DP) is commonly used in cross country skiing (XC). It is becoming more and more popular and in some competitions it is the exclusive technique. Ski poles allow a skier to apply power and force to the snow and their composition and design have a significant effect on performance. Different pole lengths and cross sections are some of the differences that have been tested. Advancements in equipment will continue to be introduced so it is i…

Partial Information Decomposition of Brain-Heart Interactions in Temporal Lobe Epilepsy in the Childhood

We apply information decomposition methods to elicit unique, redundant and synergistic causal contributions of ipsilateral and contralateral EEG activity to heart rate dynamics in epileptic children. We find that information flows from brain to heart according to opposite lateralization effects for the delta and alpha rhythms, suggesting that different neuroautonomic mechanisms take place in the pre- and post-ictal phases of temporal lobe seizures.

Subjective stress, objective heart rate variability-based stress, and recovery on workdays among overweight and psychologically distressed individual…

2015

Background: The present study aimed to investigate how subjective self-reported stress is associated with objective heart rate variability (HRV)-based stress and recovery on workdays. Another aim was to investigate how physical activity (PA), body composition, and age are associated with subjective stress, objective stress, and recovery. Methods: Working-age participants (n = 221; 185 women, 36 men) in this cross-sectional study were overweight (body mass index, 25.3-40.1 kg/m(2)) and psychologically distressed (>= 3/12 points on the General Health Questionnaire). Objective stress and recovery were based on HRV recordings over 1-3 workdays. Subjective stress was assessed by the Perceived St…

Transcultural Adaptation and Theoretical Models of Validation of the Spanish Version of the Self-Care of Heart Failure Index Version 6.2 (SCHFI v.6.2)

2021

Background: Heart failure (HF) is a major and growing public health problem worldwide. Across the world, heart failure is associated with high mortality, high hospitalization rates, and poor quality of life. Self-care is defined as a naturalistic decision-making process involving the choice of behaviors that maintain physiologic stability, the response to symptoms when they occur, and the ability to follow the treatment regimen and control symptoms. One instrument used to measure self-care is the Self Care of Heart Failure Index. Aim: The purpose of this study was to test the psychometric properties of the Spanish version of the Self Care of Heart Failure Index v.6.2 (SCHFI v.6.2). Methodol…

Kuormituskoe modernin kuvantamisen aikakaudella

2019

Kuormituskoetta käytetään sepelvaltimotaudin ja muidenkin sydänsairauksien diagnosoinnissa, ennusteen arvioinnissa, hoidon suunnittelussa ja seurannassa. Kuormituskokeen keskeisin etu on sen helppo saatavuus sekä avoterveydenhuollossa että erikoissairaanhoidossa. Rasitukseen liittyvien oireiden tai suorituskyvyn heikkenemisen yhteydessä kuormituskoe on edelleen arvokas perustutkimus. Sen käytön keskeisin rajoite liittyy sen diagnostiseen osuvuuteen, ja sepelvaltimotaudin ali- ja ylidiagnostiikan välttämiseksi kuormituskokeen käyttö tulisikin rajata liikuntakykyisiin potilaisiin, joilla taudin todennäköisyys ennen testiä on keskisuuri tai suuri. Kuormituskoe sopii potilaille, joiden lepo-EKG…

PENSARE LA CONCILIAZIONE. IL CONCETTO DI CUORE IN PASCAL

2021

La tesi di dottorato mira a mostrare il metodo e al tempo stesso il contenuto prezioso del cuore nella filosofia di Blaise Pascal. Il cuore suggerisce nella filosofia, nella lettura proposta, il tema della "conciliazione". Il tema del cuore infatti mostra non tanto o non solo una opposizione con la ragione, ma un accrescimento della ragione stessa, ovvero un recupero di quella dimensione patica che il razionalismo moderno tende a mettere da parte. This thesis aims to show the method and at the same time the precious content of the heart in the philosophy of Blaise Pascal. The heart proposes the theme of conciliation in philosophy. The theme of the heart in fact shows not an opposition with …

Bractwo Najświętszych Serc Jezusa i Maryi przy kościele parafialnym w Połocku w świetle Księgi brackiej z lat 1794-1818

2018

The fonds of National Library of Russia include a Register of Brotherhood of Sacred Hearts of Jesus and Mary in Polotsk. Besides the list of members, the manuscript includes a number of documents important for operation of the congregation. The Brotherhood operated in 1794-1818; it was run by Jesuits, who survived disbanding of the order in 1773. Membership list of the Brotherhood (approx. 11 thousand) shows a crosssection of Polish community, living mostly in territories captured by Russia after First Partition of Poland. It includes members of local elite, as well as the lowest social tiers. Russians, Germans, French and Italians also joined the Brotherhood. An important group of members …
