The effects of CO2 and tropospheric O3 on forest trees are increasingly the subject of experimental evaluation. Little is known, however, about he effects of these gases on understory plant taxa. At the Aspen free-air CO2 and O3 enrichment (Aspen FACE) site we assessed colonization and stablishment of two common forest understory species, red (Trifolium pratense) and white (Trifolium repens) cl...

Coatings with vertical gradients in composition were produced by drying an aqueous polymer dispersion containing both charged and neutral particles. After drying, the neutral component was enriched at the film/air interface. The spontaneous vertical segregation between the two types of particles goes back to a difference in collective diffusivity. As the film dries, a layer enriched in polymer ...

Ageing is associated with changes in physiology and morphology; nutritional strategies to decrease morbidity and to prolong life are of high interest. The aim of the study was to investigate the effects of lifelong supplementation with an oligofructose-enriched inulin on morphological and biological markers and lifespan in male and female rats. Male and female rats, age 3 months, were randomise...

Enrichment of zeolite and sponge as ethylene absorbent with potassium permanganate was theidea of this study to provide an efficient way to scavenge ethylene during storage period ofthree Rosa hybrida cv. ‘Shiraz’, ‘Avalanche’, and ‘After-party’ cut flowers. A preliminaryexperiment revealed that two mL of potassium permanganate solution (1 mM) was enough toenrich two gra...

Principles of lean office management increasingly call for space to be stripped of extraneous decorations so that it can flexibly accommodate changing numbers of people and different office functions within the same area. Yet this practice is at odds with evidence that office workers' quality of life can be enriched by office landscaping that involves the use of plants that have no formal work-...

Peri-implantitis represents a major complication that can compromise the success and survival of implant-supported rehabilitations. Both surgical and nonsurgical treatment protocols were proposed to improve clinical parameters and to treat implants affected by peri-implantitis. A systematic review of the literature was performed on electronic databases. The use of air-polishing powder in surgic...

Central Nervous System Oxygen Toxicity (CNS-OT) is one of the most harmful effects of Enriched Air Nitrox (EAN) diving. Protective factors of the Ketogenic Diet (KD) are antioxidant activity, the prevention of mitochondrial damage and anti-inflammatory mechanisms. We aimed to investigate if a short-term KD may reduce oxidative stress and inflammation during an hyperoxic dive. Samples from six o...

Pressure swing adsorption (PSA) technology is used in medical oxygen concentrators for selective of nitrogen under pressure from air to produce oxygen-enriched breathing. The functional material aluminosilicate zeolite like Li-13X, 5A (LTA) with a relatively high Al-content. It selectively adsorbs the into their molecular sieves due strong quadrupolar interaction between adsorbed and electrical...

Serine hydroxymethyltransferases (SHMs) are important enzymes of cellular one-carbon metabolism and are essential for the photorespiratory glycine-into-serine conversion in leaf mesophyll mitochondria. In Arabidopsis (Arabidopsis thaliana), SHM1 has been identified as the photorespiratory isozyme, but little is known about the very similar SHM2. Although the mitochondrial location of SHM2 can b...

The biomass production of Cymbopogon citratus shoots cultivated in bioreactors according to the temporary immersion (TIS) principle was assessed under different growth conditions. The effect of gassing with CO2-enriched air, reduced immersion frequency, vessel size and culture time on total phenolic and flavonoid content and free radical scavenging effect of the methanolic extracts was measured...
