It is known that non-cachectic patients with chronic obstructive pulmonary disease (COPD) respond well to rehabilitation, but whether cachectic COPD are capable of adaptive responses both important and unknown. 10 19 undertook high-intensity cycling training, at the same relative intensity, for 45 min·day −1 , 3 days·week weeks. Before after rehabilitation vastus lateralis muscle biopsies were analysed morphologically expression remodelling factors (insulin-like growth factor (IGF)-I,...
Binary and multiple stellar systems are numerous in our solar neighborhood with 80 per cent of the solar-type stars being members high order multiplicity. The Contact Binaries Towards Merging (CoBiToM) Project is a programme that focuses on contact binaries systems, as key for understanding nature. goal to investigate coalescence merging processes, final state evolution low-mass binary systems. Obtaining observational data approximately 100 eclipsing more than 400 archival aspires give...
The present study investigated how end-expiratory ribcage and abdominal volume regulation during exercise is related to the degree of dynamic chest wall hyperinflation in patients with different spirometric severity chronic obstructive pulmonary disease (COPD) based on Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification. In total, 42 COPD 11 age-matched healthy subjects were studied a ramp-incremental cycling test limit tolerance (W(peak)). Volume variations (at end...
Smoking is Greece's largest public health threat. Greece has the highest adult smoking prevalence among all E.U countries, which in turn possibly predisposes Greek children and adolescents to smoke. The purpose of our study was research into habits preschool children's parents since that age could be vulnerable parental negative role modeling investigate necessity conducting a awareness programme aimed at general population. A cross-sectional performed on enrolled kindergarten western...
ABSTRACT Ultra-short orbital period contact binaries (Porb < 0.26 d) host some of the smallest and least massive stars. These systems are faint rare, it is believed that they have reached a configuration after several Gyrs evolution via angular momentum loss, mass transfer, loss through stellar wind processes. This study conducted in frame Contact Binaries Towards Merging (CoBiToM) Project presents results from light curve analysis 30 ultra-short binaries, with aim to investigate...
Childhood obesity has increased dramatically in the past few decades both developed and developing countries. The objectives of this study were to estimate prevalence weight children adolescents on a remote Greek island Aegean Sea, assess factors influencing phenomenon.A cross-sectional was conducted involving aged 8-16 years, resident Kalymnos, Greece. Their height measured school environment. Information about children's leisure habits, plain dietary history, whether they exposed tobacco...
This study was designed to assess quadriceps oxygenation during symptom‐limited and constant‐load exercise in patients with chronic obstructive pulmonary disease (COPD) healthy age‐matched controls. Thirteen male COPD [FEV 1 : 43±5% predicted (mean±SEM)] seven controls performed an incremental test at peak work rate (WR) a 75% WR on cycle ergometer. Quadriceps hemoglobin saturation (StO 2 ) measured by continuous‐wave near‐infrared spectrophotometry throughout both tests. StO is the ratio of...
This study investigated the predictive relationship among Trait Emotional Intelligence (TEI), self-esteem, and trait anxiety within a sample of Greek native individuals (N=136), employing multiple regression analysis. The Questionnaire (TEIQue), Spielberger State-Trait Anxiety Inventory (STAIT-5), Rosenberg Self-Esteem Scale were administered for data collection. Results revealed robust positive correlation between TEI self-esteem (r= 0.61, p<0.001), with both variables emerging as...
Families of asteroids generated by the collisional fragmentation a common parent body have been identified using clustering methods in their proper orbital element space. An alternative method has developed order to identify families from correlation between asteroid fragment sizes and semi-major axis distance family centre (V-shape). This shown be effective cases very diffuse that formed billions years ago. We obtained photometric observations construct rotational light curves; we combine...
D-type asteroids are among the most primitive small bodies of solar system. Believed to be formed in outer system, a minor fraction these faint objects can found near-Earth region. Some were suspected extinct comets disguised as asteroids. If could represent comets, they would offer us unique opportunity investigate relationship between two classes our To provide new insights into asteroids' composition and dynamical evolution possible relation with we introduce mission concept CARINA (Comet...
Asynchronous breathing movements may be observed in the presence of pulmonary disease, such as chronic obstructive disease (COPD). This study was undertaken an attempt to propose a reliable methodology quantify this asynchrony. Five methods for estimating phase differences between two signals, based on angle Fourier Transform (PhD(FT)), paradoxical motion (PhD(PM)), Lissajous figure (PhD(LF)), maximal linear correlation (PhD(P)) and least-squares filtering (PhD(LS)), were compared....
Introduction:Numerous energetic collisions between asteroids in the inner Solar System have led to creation of groups fragments, known as asteroid collisional families. These families populate Main Belt, each family typically originating from a single parent body that was shattered [1]. The fragments same collision form characteristic V-shape plane defined by inverse diameter (1/D) and orbital semimajor axis (a), due Yarkovsky effect [2, 3]. It is thermal force, which cause outward drift...
Headache is one of the most common neurological symptoms that lead patients to ED. The latest data show 50-75% adults globally, have experienced headache at least once during past year and about 1-4% can be affected for several days per month, resulting in a huge disease load increases cost health care worldwide.

AbstractThe so-called &#8220;primordial family&#8221;, is a recently discovered collisional family [1] that could be as old the Solar system. It contains low-albedo asteroids and located in inner Main Belt. This was identified by V-shape technique [2] estimated to at least 4 Gyr old, meaning occurred before giant planet instability [3].&#160; Asteroids 2768 Gorky (1972 RX3) 9086 (1995 SA3) are members of primordial have been observed order determine their rotational period, spin...

However, there is growing evidence that some real are larger than corresponding cluster objects elements, as well escaped...
IntroductionWe invite observers to join an international observing campaign and obtain light curve of a selected number the most ancient asteroids. Analysis these data will be important reconstruct original state asteroid belt, which is crucial problem planetary science. This can reconstructed through identification oldest families. Traditional methods, like Hierarchical Clustering Methods (Zappala et al., 1990; HCM), have difficulties recognise Gyr- older families, whose members are very...
