Chemical composition of the essential oil from Pulicaria vulgaris var. graeca (Sch.-Bip.) Fiori (Asteraceae) growing wild in Sicily and its antimicro…
2015
In this study the chemical composition of the essential oil from aerial parts of Pulicaria vulgaris var. graeca (Sch.-Bip.) Fiori collected in Sicily was evaluated by GC and GCâMS. The main components of P. vulgaris var. graeca oil were hexadecanoic acid (21.7%), β-caryophyllene (14.3%) and geranyl propionate (8.2%). The comparison with other studied oils of genus Pulicaria is discussed. Antibacterial activity against several bacteria, including some ones infesting historical art craft, was also determined.
Inter‐individual variation in responses to resistance training in cardiometabolic health indicators
2020
Abstract Resistance training (RT) may improve metabolic health; however, the extent of its effectiveness is constantly evaluated to assess improvements in the group means, thus obscuring the heterogeneous individual effects. This study investigated inter‐individual variation in responses to RT as reflected in metabolic health indicators and how age, sex, nutrition and pre‐training phenotypes are associated with such variabilities. Methods Previously collected data of men and women (39‐73 years, 135 trained, 73 non‐trained controls) were pooled for analysis. Measurements were taken twice before training to estimate individual day‐to‐day variations and measurement errors (n=208). The individu…
Comparison of the effects of high-intensity interval running, high-intensity interval circuit training and steady-state running on body composition a…
2015
Introduction. The measurement of body composition is important for several reasons, but nowadays when obesity and overweight are common problems all over the world even more attention should be given to body composition. Excess amount of fat is itself a risk for health, but it also predisposes to many diseases, one of which is diabetes. It has been shown that with regular physical activity and exercise the body composition and body’s glucose regulation can be improved. In common activity guidelines the amount of traditional endurance and resistance training takes hours per week to perform to fill the recommendations. However, since it has been shown that one of the most common reasons for n…
A luminal glycoprotein drives dose-dependent diameter expansion of the Drosophila melanogaster hindgut tube
2012
An important step in epithelial organ development is size maturation of the organ lumen to attain correct dimensions. Here we show that the regulated expression of Tenectin (Tnc) is critical to shape the Drosophila melanogaster hindgut tube. Tnc is a secreted protein that fills the embryonic hindgut lumen during tube diameter expansion. Inside the lumen, Tnc contributes to detectable O-Glycans and forms a dense striated matrix. Loss of tnc causes a narrow hindgut tube, while Tnc over-expression drives tube dilation in a dose-dependent manner. Cellular analyses show that luminal accumulation of Tnc causes an increase in inner and outer tube diameter, and cell flattening within the tube wall,…
From the forest to the plate – Hemicelluloses, galactoglucomannan, glucuronoxylan, and phenolic-rich extracts from unconventional sources as function…
2021
This study aimed to characterise pressurised hot water (PHW) extracts from nonconventional sources of functional carbohydrates and phenolic compounds in terms of antioxidant capacity, antiviral activity, toxicity, and human erythrocytes’ protection antidiabetic potential. PHW extracts of Norway spruce bark (E1 + E2) and Birch sawdust (E3 + E4) contained mostly galactoglucomannan and glucuronoxylan. In contrast, samples E5 to E9 PHW extracted from Norway spruce, and Scots pine bark are rich sources of phenolic compounds. Overall, phenolic-rich extracts presented the highest inhibition of α-amylase and α-glucosidase and protection against stable non-enveloped enteroviruses. Additionally, all …
Aqueous-phase reactive species formed by fine particulate matter from remote forests and polluted urban air
2021
In the aqueous phase, fine particulate matter can form reactive species (RS) that influence the aging, properties, and health effects of atmospheric aerosols. In this study, we explore the RS yields of aerosol samples from a remote forest (Hyytiälä, Finland) and polluted urban locations (Mainz, Germany; Beijing, China), and we relate the RS yields to different chemical constituents and reaction mechanisms. Ultra-high-resolution mass spectrometry was used to characterize organic aerosol composition, electron paramagnetic resonance (EPR) spectroscopy with a spin-trapping technique was applied to determine the concentrations of ⚫OH, O2⚫-, and carbon- or oxygen-centered organic radicals, and a …
Variations in the Chemical Composition of the Essential Oil of Lavandula angustifolia Mill., Moldoveanca 4 Romanian Variety
2020
International audience; In this research, the variations in the chemical composition of the Lavandula angustifolia Mill. essential oil, the Romanian variety Moldoveanca 4, obtained from the same culture, in the same harvesting and extraction conditions, during the years 2016-2018, representing the years 2-4 of culture. Lavandula angustifolia Mill. flowers were supplied from an ecological-crops from N-E Romania and the essential oils were obtained by hydro distillation of freshly harvested flowers. To determine the chemical composition, the essential oil was semi-quantitatively analysed by using gas chromatography coupled with mass spectrometry (GC-MS). In all the samples, 30 organic compoun…
Substrat jako fundament konwencjonalizacji wtórnej sielanki staropolskiej
2022
Artykuł pt. Substrat jako fundament konwencjonalizacji wtórnej staropolskiej sielanki jest analizą najważniejszej zasady tworzącej konwencję tego gatunku, a mianowicie reguły dwupłaszczyznowości kompozycyjnej. Autorka na przykładach utworów takich poetów, jak: Szymon Szymonowicz, Szymon Zimorowicz, Jan Gawiński, Samuel Twardowski czy Adrian Wieszczycki omawia etap kształtowania się konwencji gatunku sielankowego. Następnie ukazuje zależność pomiędzy zmianami w warunkach literackich i kulturowych oraz tych, które zaszły w percepcji czytelników, a ich wpływem na ewolucję ustalonej konwencji. Obserwowane zmiany w obrębie konwencji zostały opracowane w odniesieniu do koncepcji substratu gatunko…
L'interprete al cinema: stereotipi, pregiudizi e realtà
2020
The figure of the interpreter in history has always oscillated between visibility and invisibility. Although today there is a tendency to give it increasing recognition, some categories (cultural mediators, war and sign interpreters) still remain in a poorly recognized situation and often operate in precarious working conditions. The interpreter as a subject of study has been present in world literature for years. We will investigate what has become the interpreter as a subject in world cinema. What is the semiotic process for which a given image of the interpreter communicates a certain cliché or suggests certain characteristics that the director (or the screenwriter) wanted to highlight. …
Body Composition, Energy Availability, Training, and Menstrual Status in Female Runners.
2020
Purpose: To determine body composition, energy availability, training load, and menstrual status in young elite endurance running athletes (ATH) over 1 year, and in a secondary analysis, to investigate how these factors differ between nonrunning controls (CON), and amenorrheic (AME) and eumenorrheic (EUM) ATH. Correlations to injury, illness, and performance were also examined. Methods: Altogether 13 ATH and 8 CON completed the Low Energy Availability in Females Questionnaire. Anthropometric, energy intake, and peak oxygen uptake assessments were made at 4 time points throughout the year: at baseline post competition season, post general preparation, post specific preparation, and post comp…
