TL;DR: In this paper, a garlic sample was leached with water and the aqueous extract was fractionated by preparative size-exclusion chromatography and the chromatographic purity of the fraction was verified by reversed phase chromatography with inductively coupled mass spectrometric detection.

TL;DR: In this article, an antimicrobial composition for combatting infections is provided, which is a controlled release glass having two or more agents selected from the group consisting of metals, selenium and boron.
Abstract: There is provided an antimicrobial composition for combatting infections. The material is a controlled release glass having two or more agents selected from the group consisting of metals, selenium and boron. Preferably the agents are selected from the group consisting of copper, silver, magnesium, zinc, cerium, manganese bismuth, selenium and boron. The combinations of copper and silver and of copper and zinc are particularly preferred and exhibit synergistic activity. The antimicrobial composition is effective against infections due to Proteus spp.

TL;DR: Overall, there is the need to reconsider the selenium standards for dietary intake, drinking water, outdoor and indoor air levels, taking into account the recently discovered adverse health effects of low-doseSelenium overexposure, and carefully assessing the significance ofselenium-induced proteomic changes.
Abstract: New data have been accumulated in the scientific literature in recent years which allow a more adequate risk assessment of selenium with reference to human health. This new evidence comes from environmental studies, carried out in populations characterized by abnormally high or low selenium intakes, and from high-quality and large randomized controlled trials with selenium recently carried out in the US and in other countries. These trials have consistently shown no beneficial effect on cancer and cardiovascular risk, and have yielded indications of unexpected toxic effects of selenium exposure. Overall, these studies indicate that the minimal amount of environmental selenium which is source of risk to human health is much lower than anticipated on the basis of older studies, since toxic effects were shown at levels of intake as low as around 260 µg/day for organic selenium and around 16 µg/day for inorganic selenium. Conversely, populations with average selenium intake of less than 13-19 µg/day appear to be at risk of a severe cardiomyopathy, Keshan disease. Overall, there is the need to reconsider the selenium standards for dietary intake, drinking water, outdoor and indoor air levels, taking into account the recently discovered adverse health effects of low-dose selenium overexposure, and carefully assessing the significance of selenium-induced proteomic changes.
