Drug profiles Drug profiles scientifically sound descriptions of drugs in the form of ‘drug profiles’. Presented in a standardised way, each profile briefly gives the chemistry, pharmacology, synthesis and precursors of each substance, as well as analysis, physical form (e.g. powder, tablet) and mode of use (e.g. ingested, snorted, injected). Most of the substances covered are controlled internationally by United Nations conventions. Presented in a standardised way, each profile briefly gives the chemistry, pharmacology, synthesis and precursors of each substance, as well as analysis, physical form (e.g. powder, tablet) and mode of use (e.g. ingested, snorted, injected). Where appropriate, the profiles also contain sections on prevalence, street price and typical levels of purity, which will be updated annually on the basis of information provided by the Reitox network. The profiles were conceived to offer EMCDDA audiences clear and easily accessible information on individual drugs.
ITIS Systematics is the branch of biology concerned with classification and nomenclature. It is sometimes used synonymously with taxonomy. In their 1970 publication Systematics in Support of Biological Research, Michener et al. defined systematic biology and taxonomy as: Systematic biology (hereafter called simply systematics) is the field that (a) provides scientific names for organisms, (b) describes them, (c) preserves collections of them, (d) provides classifications for the organisms, keys for their identification, and data on their distributions, (e) investigates their evolutionary histories, and (f) considers their environmental adaptations...Taxonomy is that part of Systematics concerned with topics (a) to (d) above. Identifying species, their relationships and evolutionary hierarchies, is critical to saving biodiversity. ITIS (Integrated Taxonomic Information System) was established to address this priority.

Essential First Aid Item: Activated Carbon Activated carbon, in powdered form, should be in every medicine cabinet and first aid kit. It is also known as activated charcoal. It is used around the world as a universal antidote for hundreds of poisons, including arsenic, mercury, pesticides, strychnine, warfarin, hemlock, E. Coli endotoxin, and gasoline. Over 4,000 chemicals, drugs, plant and microbial toxins, allergens, venoms, and wastes are effectively neutralized by activated charcoal, when it is given in sufficient quantities. In 1813, French chemist Michel Bertrand swallowed five grams of arsenic trioxide: 150 times the lethal dose. In 1831, in front of his distinguished colleagues at the French Academy of Medicine, Professor Touery drank a deadly cocktail of strychnine and lived to tell the tale. We witnessed the saving power of activated charcoal ourselves, when one member of our household experienced a severe allergic reaction to an unknown ingredient from a restaurant.

Case Study of Botany Research in Tropics Nestled within the Hang Dong district, Chiang Mai, Thailand, is a 10 acre botanical garden called Dokmai Garden. Run by the Thai family Seehamongkol, it boasts over 1,000 plant species, including orchids, laurels, banana plants, birds-of-paradise plants, and gingers. The Seehamongkol family, and the garden's biologist and Director, Dr. Eric Danell, have the lucky fortune of not only working in this garden, but also of calling it home. While living amidst such a paradise is undeniably enchanting, for Dr. Dr. Eric's passion, however, is gardens. Fortunately for Dr. Since discovering BHL, Eric uses it several times a week, typically verifying plant species descriptions online but occasionally also downloading PDFs. The true magic of BHL for Danell, however, is the truly global access it provides. Being located in a developing country also provides opportunities for Dr.
Archive CETAF – Consortium of European Taxonomic Facilities Erowid Cavendishia ends a 38 year wait for its own name This plant was collected in 1976 by one of RBGE’s senior botanists, George Argent, who has now retired but is still working hard collecting and naming plants. It was collected from the lower montane forests of southern Ecuador and he says that it rained continuously for six weeks on his collecting trip which was why all the plants were growing so well! Ecuador is at the top of South America and is so called because it lies on the equator so the day length is the same all year round, 12 hours of day and 12 hours of night. The lowlands and coastal regions of Ecuador experience warm tropical temperatures but higher up in the mountains it can get a lot cooler. This plant has been growing in the tropical glasshouse at Edinburgh which is heated to a minimum temperature of 18°C. It has only flowered three times since 1976 and it has taken us aback with its grace and fine features. The flowers are held at the end of long, fine, woody stems and the leaves are narrow and elegant.
Bufotenin Bufotenin (5-HO-DMT, N,N-dimethylserotonin), is a tryptamine related to the neurotransmitter serotonin. It is an alkaloid found in the skin of some species of toads; in mushrooms, higher plants, and mammals.[1] The name bufotenin originates from the Bufo genus of toads, which includes several species of psychoactive toads, most notably Incilius alvarius, that secrete bufotoxins from their parotoid glands.[2] Bufotenin is similar in chemical structure to the psychedelics psilocin (4-HO-DMT), 5-MeO-DMT, and DMT, chemicals which also occur in some of the same fungus, plant, and animal species as bufotenin. The psychoactivity of bufotenin has been disputed, though recent studies suggest it is similar in nature to 5-MeO-DMT. Nomenclature[edit] Bufotenin (bufotenine) is also known by the chemical names 5-hydroxy-N,N-dimethyltryptamine (5-HO-DMT), N,N-dimethyl-5-hydroxytryptamine, dimethyl serotonin,[3] and mappine.[3] History[edit] Sources[edit] Toads[edit] Anadenanthera seeds[edit] In 1956, Dr.
Flowers mislead traditional taxonomy For hundreds of years, plant taxonomists have worked to understand how species are related. Until relatively recently, their only reliable source of information about these relationships was the plants' morphology—traits that could be observed, measured, counted, categorized, and described visually. And paramount among these morphological traits were aspects of flower shape and arrangement. In the papilionoid legumes—a large, diverse group that includes the common pea and bean—most species have highly specialized, "butterfly-shaped" flowers with bilateral symmetry, fused stamens, and strongly differentiated standard, wing, and keel petals. Lead author Domingos Cardoso (Universidade Estadual de Feira de Santana in Bahia, Brazil) was intrigued by the floral diversity of papilionoid legumes. This shows a mass flowering of Luetzelburgia bahiensis in a Caatinga dry setting at Morro do Chapéu, Bahia, Brazil. (Photo Credit: Courtesy of Domingos Cardoso.)
The Psychadellic Chemist By DENNIS ROMERO LAFAYETTE, Calif. -- Perhaps it was a sign of things to come when a seven-story Monterrey Pine came crashing down on the property of old Alexander T. Shulgin--Sasha, they call him--missing his musty cobweb-entangled drug lab by inches. It could have been a good sign because the cantankerous 70-year-old wasn't around the back-yard workshop conducting one of his legendary experiments, which have been known to involve him downing any number of the new psychedelic drugs he invents in the name of science. Imagine losing your mind on some unknown compound with unknown powers (some of this stuff makes LSD look like Vitamin D)--and a tree the length of three buses rocks your world to Richter proportions. Maybe, though, it was a sign of nefarious things to come. To tell the truth, Sasha Shulgin doesn't much care anymore what the government thinks. He's tippy-toed around the law and the lawmen for long enough--30 years now. Shulgin met Ann at Berkeley in 1979.
