Artemisinin - Wikipedia, the free encyclopedia
Artemisinin (pronounced /ɑːtə'misinən/) is a drug used to treat multi-drug resistant strains of falciparum malaria. The compound (a sesquiterpene lactone) is isolated from the plant Artemisia annua. Not all plants of this species contain artemisinin. Apparently it is only produced when the plant is subjected to certain conditions, most likely biotic or abiotic stress. It can be synthesized from artemisinic acid.[1] The drug is derived from a herb used in Chinese traditional medicine, though it is usually chemically modified and combined with other medications.
Artemisinin is under early research and testing for treatment of cancer, primarily by researchers at the University of Washington.[7][8] Artemisinin has a peroxide lactone group in its structure. It is thought that when the peroxide comes into contact with high iron concentrations (common in cancerous cells), the molecule becomes unstable and releases reactive oxygen species. It has been shown to reduce angiogenesis and the expression of vascular endothelial growth factor in some tissue cultures.
Zakynthos - Wikipedia, the free encyclopedia
Zakynthos (Greek: Ζάκυνθος(Ell-Zakynthos.ogg [ˈzacinθos] (help·info)), Venetian: Zacinto; Italian: Zante(a form often used in English)), the third largest of the Ionian Islands, covers an area of 410 km2 (158 sq mi) and its coastline is roughly 123 km (76 mi) in length. The island is named after Zakynthos, the son of a legendary Arcadian chief Dardanus. The name, like all similar names ending in -nthos, is pre-Mycenaean or Pelasgian in origin. Zakynthos has a thriving tourism industry.
Timeline of evolution - Wikipedia, the free encyclopedia
This timeline of the evolution of life outlines the major events in the development of life on the planet Earth (See Organism). For a thorough explanatory context, see the history of Earth, and geologic time scale. The dates given in this article are estimates based on scientific evidence.
In biology, evolution is the process by which populations of organisms acquire and pass on novel traits from generation to generation. Its occurrence over large stretches of time explains the origin of new species and ultimately the vast diversity of the biological world. Contemporary species are related to each other through common descent, products of evolution and speciation over billions of years.
Timeline of human evolution - Wikipedia, the free encyclopedia
The timeline of human evolution outlines the major events in the development of human species, and the evolution of humans' ancestors. It includes a brief explanation of some animals, species or genera, which are possible ancestors of Homo sapiens sapiens. It begins with the origin of life and presents a possible line of descendants that led to humans. This timeline is based on studies from paleontology, developmental biology, morphology and from anatomical and genetic data. The study of human evolution is a major component of anthropology.
Navagio - Wikipedia, the free encyclopedia
Navagio Beach (Greek: Ναυάγιο), or the Shipwreck, is an isolated sandy cove on Zakynthos island and one of the most famous beaches in Greece. It is notable because it is home to the wreck of the alleged smuggler ship Panagiotis; thus, it is often referred to as 'Smugglers Cove'.
WHFoods: A Healthy Way to Roast Almonds
Roasting brings out the flavor of the nuts, and develops their sweetness. It is safe to roast nuts if done at a low temperature-typically a 160-170 degree Fahrenheit (71-76 Celsius) oven (at higher temperatures than this, research clearly shows damage to nuts' delicate fats) for 15-20 minutes will do the trick. Place nuts on a cookie sheet in a single layer. To enhance the "roasted" flavor, try putting a little Bragg's Liquid Aminos or soy sauce into a spray bottle and misting the nuts before roasting.

Coffee roasting - Wikipedia, the free encyclopedia
Roasting coffee transforms the chemical and physical properties of green coffee beans into roasted coffee products. The roasting process is what produces the characteristic flavor of coffee by causing the green coffee beans to expand and to change in color, taste, smell, and density. Unroasted beans contain similar acids, protein, and caffeine as those that have been roasted, but lack the taste. It takes heat to speed up the Maillard and other chemical reactions that develop and enhance the flavour.
As green coffee is more stable than roasted, the roasting process tends to take place close to where it will be consumed. This reduces the time that roasted coffee spends in distribution, helping to maximize its shelf life. The vast majority of coffee is roasted commercially on a large scale, but some coffee drinkers roast coffee themselves in order to have more control over the freshness and flavour profile of the beans.

Vitamin D - Linus Pauling Institute at Oregon State University
Vitamin D is a fat-soluble vitamin that is essential for maintaining normal calcium metabolism (1). Vitamin D3 (cholecalciferol) can be synthesized by humans in the skin upon exposure to ultraviolet-B (UVB) radiation from sunlight, or it can be obtained from the diet. Plants synthesize ergosterol, which is converted to vitamin D2 (ergocalciferol) by ultraviolet light. Vitamin D2 is less active in birds than vitamin D3 and may also be less active in humans (2). When exposure to UVB radiation is insufficient for the synthesis of adequate amounts of vitamin D3 in the skin, adequate intake of vitamin D from the diet is essential for health.
Brain (as food) - Wikipedia, the free encyclopedia
Like most other internal organs, or offal, the brain can serve as nourishment. This includes the brains of pigs, cattle, monkeys, and in rare circumstances, humans, or even cats, birds, or marine mammals such as whales. In many cultures, different types of brain are considered a delicacy.
Ursolic acid - Wikipedia, the free encyclopedia
Ursolic acid is a pentacyclic triterpene acid, used in cosmetics,[2] that is also capable of inhibiting various types of cancer cells by inhibiting the STAT3 activation pathway[3][4] and human fibrosarcoma cells by reducing the expression of matrix metalloproteinase-9 by acting through the glucocorticoid receptor.
Ursolic acid is present in many plants, including apples, basil, bilberries, cranberries, elder flower, peppermint, rosemary, lavender, oregano, thyme, hawthorn, prunes. Apple peels contain high quantity of ursolic acid and related compounds which are responsible for the anti-cancer activity of apple. Ursolic acid can also serve as a starting material for synthesis of more potent bioactive derivatives, such as anti-tumor agents
