Heritability of Lung Function: A Twin Study Among Never-Smoking Elderly Women
2011
Most studies on lung function heritability have been conducted in smokers and non-smokers using cross-sectional study design. Smoking patterns may, however, confound the contribution of genetic factors. We investigated heritability of forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and FEV1/FVC ratio longitudinally, excluding the effects of smoking. A sample of never smoking female twins (n = 374), aged 63–76 at baseline, answered health questionnaires and attended spirometry in years 2000 and 2003. Bivariate structural equation modeling, restricted to adequate spirometry performances (baseline n = 339, follow-up n = 252), was used to estimate genetic and environ…
Reversal of age-associated frailty by controlled physical exercise: The pre-clinical and clinical evidences.
2019
Demographic aging is one of the most serious challenges facing our society. Although we live longer, we do not live better because it is considered that approximately 16–20% of our life is spent in late-life morbidity. Older people have the greatest risk of developing frailty increasing the risk of presenting various adverse health events such as low quality of life, disability, hospitalization and even death. Frail men and women over 65 years old have lower muscle quality and muscle mass and higher percentage of body fat than non-frail people of the same age. In this review we will address the main physiological changes in the muscular and nervous system associated to aging. More specifica…
Physical performance in relation to menopause status and physical activity
2018
Objective: The aim of this study was to examine differences in physical performance (muscle power, muscle strength, aerobic capacity, and walking speed) across menopausal stages and potential of leisure physical activity (PA) to modify the impact of menopause on physical performance. Methods: In this cross-sectional study, women aged 47 to 55 were randomly selected from the Finnish National Registry and categorized as premenopausal (n ¼ 233), perimenopausal (n ¼ 381), or postmenopausal (n ¼ 299) based on serum concentrations of follicle-stimulating hormone and bleeding diary. Physical performance was measured by knee extension force, handgrip force, vertical jumping height, maximal walking …
In-situ transformation of iron-bearing minerals in marshland-derived paddy subsoil
2016
Transformations of Fe-bearing minerals under alternating redox conditions are not fully understood. In-situ approaches under field conditions have rarely been used. We exposed mesh bags containing ferrihydrite, goethite or nontronite to changing redox conditions in subsoil that had been under paddy management for 100, 700 and 2000 years. After 12 months, the minerals were retrieved and analysed for organic carbon and by X-ray diffraction; in addition, nontronite was analysed for cation exchange capacity and by Mossbauer spectroscopy at 278 and 4.2 K. Field exposure of the test minerals was complemented by measurements of soil redox potential and analyses of soil water. Minerals accumulated …
The Spanish Case: The Housing Market Bubble and External Disequilibria
2013
The chapter recalls the major issues at stake in the Spanish economy since 1996, a time when financial markets started to discount the Spanish entry into the Eurozone. We start with a brief analysis of the most recent economic developments, and the current macroeconomic imbalances. As of 2007, the Spanish economy underwent its worst period in recent history, since the Stabilisation Plan was implemented in 1959. When 2008 came, however, what was most worrying was the sense of disarray that the Government projected: it simply took measures against the global financial crisis, as though this were the major, and indeed, the only crisis to cope with. Nevertheless, what affected the Spanish econo…
Experimentelle Untersuchungen über die Resorptionsfähigkeit des Stratum synoviale
1961
Unsere Versuche zeigen, das das Stratum synoviale eine gute Resorptionsfahigkeit besitzt. Eine intraartikular injizierte wasrige Losung wird innerhalb von 20–25 min in die Blutbahn aufgenommen. Durchblutung und Resorption unterliegen den gleichen vegetativ nervosen Regulationen wie in anderen Korpergebieten. Sie konnen durch eine Entzundung an gelenkfernen Gebieten, reflektorisch durch eine Entzundung der Haut uber dem Gelenk, durch ortliche oder intravenose Injektion von Adrenalin, durch eine Barbituratnarkose und Muskelrelaxantien im Sinne einer Verzogerung beeinflust werden. Cortison hat am gesunden Stratum synoviale keinen Einflus auf die Resorption. Jede Entzundung des Stratum synovial…
Evaluation of the Bioaccessibility of Antioxidant Bioactive Compounds and Minerals of Four Genotypes of Brassicaceae Microgreens
2019
Microgreens constitute an emerging class of fresh, healthy foods due to their nutritional composition. In this study the content of minerals and antioxidant bioactive compounds, and for the first time bioaccessibility, were evaluated in broccoli (Brassica oleracea L. var. italica Plenck), green curly kale (Brassica oleracea var. sabellica L.), red mustard (Brassica juncea (L.) Czern.) and radish (Raphanus sativus L.) hydroponic microgreens. Macro- (K, Ca, Mg) and oligo-elements (Fe, Zn), ascorbic acid, total soluble polyphenols, total carotenoids, total anthocyanins, total isothiocyanates and total antioxidant capacity (Trolox Equivalent Antioxidant Capacity and Oxygen Radical Absorbance Ca…
Enhancing Bioactive Antioxidants’ Extraction from “Horchata de Chufa” By-Products
2018
During the production of a traditional drink produced from the tubers of Cyperus esculentus L. also known as “horchata de chufa,” a high quantity of by-products are generated. These by-products are rich with valuable biological compounds, hence, there is a need to report their extraction conditions for further use in food production as raw materials. Therefore, the objective of this study was to evaluate and improve the conventional extraction process, applied for recovery of phenolic compounds, total flavonoids, and total antioxidant capacity from the by-products. Independent variables for extraction were: (i) Solvent type (mixtures of ethanol-water (v/v) at 0%, 25% and 50%)
Efectos del entrenamiento de la fuerza con resistencia variable elástica a lo largo de la vida: una revisión sistemática
2020
The benefits of strength training programs with isoto-nic free weights or machines have been well-documen-ted in all age groups. However, exercise and healthcare professionals sometime question whether it is possible to obtain the same results with devices of variable re-sistance, such as elastic bands. To answer this question, the purpose of this systematic review was to identify and summarize the positive effects of elastic resistance exercises used across the lifespan on health outcomes including body composition, functional and performan-ce capacity, and biochemical variables. A secondary aim was to identify common dosage parameters of strength training programs using elastic resistance…
Nutrition Knowledge Is Associated with Energy Availability and Carbohydrate Intake in Young Female Cross-Country Skiers
2021
The aim of this study was to provide information on energy availability (EA), macronutrient intake, nutritional periodization practices, and nutrition knowledge in young female cross-country skiers. A total of 19 skiers filled in weighted food and training logs before and during a training camp. Nutrition knowledge was assessed via a validated questionnaire. EA was optimal in 11% of athletes at home (mean 33.7 ± 9.6 kcal·kgFFM−1·d−1) and in 42% at camp (mean 40.3 ± 17.3 kcal·kgFFM−1·d−1). Most athletes (74%) failed to meet recommendations for carbohydrate intake at home (mean 5.0 ± 1.2 g·kg−1·d−1) and 63% failed to do so at camp (mean 7.1 ± 1.6 g·kg−1·d−1). The lower threshold of the pre-ex…
