Coutoubea spicata is a species of flowering plant from the genus Coutoubea . [1]
Coutoubea spicata is a 1 m tall creamy-white flowered gentian. [2] It is a bitter tonic, which in the 19th century was used as emmenagogues, anthelmintics, and for the removal of intestinal obstructions. [3] More recently, this plant has been studied for its potential antidiabetic and antimalaria properties. [4] [5]
Spearmint, also known as garden mint, common mint, lamb mint and mackerel mint, is a species of mint, Mentha spicata (, native to Europe and southern temperate Asia, extending from Ireland in the west to southern China in the east. It is naturalized in many other temperate parts of the world, including northern and southern Africa, North America, and South America. It is used as a flavouring in food and herbal teas. The aromatic oil, called oil of spearmint, is also used as a flavoring and sometimes as a scent.
A circadian rhythm, or circadian cycle, is a natural, internal process that regulates the sleep–wake cycle and repeats roughly every 24 hours. It can refer to any process that originates within an organism and responds to the environment. These 24-hour rhythms are driven by a circadian clock, and they have been widely observed in animals, plants, fungi and cyanobacteria.
Herbal medicine is the study of pharmacognosy and the use of medicinal plants, which are a basis of traditional medicine. With worldwide research into pharmacology, some herbal medicines have been translated into modern remedies, such as the anti-malarial group of drugs called artemisinin isolated from Artemisia annua, a herb that was known in Chinese medicine to treat fever. There is limited scientific evidence for the safety and efficacy of plants used in 21st century herbalism, which generally does not provide standards for purity or dosage. The scope of herbal medicine commonly includes fungal and bee products, as well as minerals, shells and certain animal parts. Herbal medicine is also called phytomedicine or phytotherapy.
Acrophobia is an extreme or irrational fear or phobia of heights, especially when one is not particularly high up. It belongs to a category of specific phobias, called space and motion discomfort, that share both similar causes and options for treatment.
Quassia amara, also known as amargo, bitter-ash, bitter-wood, or hombre grande is a species in the genus Quassia, with some botanists treating it as the sole species in the genus. The genus was named by Carl Linnaeus who named it after the first botanist to describe it: the Surinamese freedman Graman Quassi. Q. amara is used as insecticide, in traditional medicine and as additive in the food industry.
The name Catuaba is used for the infusions of the bark of a number of trees native to Brazil. The most widely used barks are derived from the trees Trichilia catigua and Erythroxylum vaccinifolium. Other catuaba preparations use the bark of trees from the following genera or families: Anemopaegma, Ilex, Micropholis, Phyllanthus, Secondatia, Tetragastris and species from the Myrtaceae.
Yoshinori Ohsumi is a Japanese cell biologist specializing in autophagy, the process that cells use to destroy and recycle cellular components. Ohsumi is a professor at Tokyo Institute of Technology's Institute of Innovative Research. He received the Kyoto Prize for Basic Sciences in 2012, the 2016 Nobel Prize in Physiology or Medicine, and the 2017 Breakthrough Prize in Life Sciences for his discoveries of mechanisms for autophagy.
Tasuku Honjo is a Japanese physician-scientist and immunologist. He won the 2018 Nobel Prize in Physiology or Medicine and is best known for his identification of programmed cell death protein 1 (PD-1). He is also known for his molecular identification of cytokines: IL-4 and IL-5, as well as the discovery of activation-induced cytidine deaminase (AID) that is essential for class switch recombination and somatic hypermutation.
Satoshi Ōmura is a Japanese biochemist. He is known for the discovery and development of hundreds of pharmaceuticals originally occurring in microorganisms. In 2015, he was awarded the Nobel Prize in Physiology or Medicine jointly with William C. Campbell for their role in the discovery of avermectins and ivermectin, the world's first endectocide and a safe and highly effective microfilaricide. It is believed that the large molecular size of ivermectin prevents it from crossing the blood/aqueous humour barrier, and renders the drug an important treatment of helminthically-derived blindness.
Alison Ruth Mercer is a New Zealand zoologist based at the University of Otago, with a particular interest in the brain physiology of bees. She was elected a member of the National Academy of Sciences in 2022.
Sherwood Leslie Gorbach is an Emeritus Professor at Tufts University School of Medicine. He was editor-in-chief of the journal Clinical Infectious Diseases from 2000 to 2016.
Michael Douglas Crisp is an emeritus professor in the Research School of Biology at the Australian National University located in Canberra. In 1976 he gained a PhD from the University of Adelaide, studying long-term vegetation changes in arid zones of South Australia. In 2020 Professor Crisp moved to Brisbane where he has an honorary position at the University of Queensland. Together with others he has revised various pea-flowered legume genera.
John Alan (Jack) Elix emeritus professor in chemistry at the Australian National University, is an organic chemist who has contributed in many fields: lichenology, lichen chemotaxonomy, plant physiology and biodiversity and natural product chemistry. He has authored 2282 species names, and 67 genera in the field of mycology.
Andrea A. Hayes Dixon is an American surgeon. She was the first pediatric surgeon to perform a high-risk, life-saving procedure in children with a rare form of cancer and developed the first orthotropic xenograft model of metastatic Ewing's sarcoma. In 2002, she became the first African American female pediatric surgeon board-certified in the United States.
Philippa Marion Wiggins was a New Zealand academic, who made significant contributions to the understanding of the structure of water in living cells.
Yariv reagent is a glycosylated phenolic compound that binds strongly to galactans and arabinogalactan proteins. It can therefore be used in their detection, quantification, precipitation, isolation, staining, and interfere with their function. It was initially synthesised in 1962 as an antigen for carbohydrate-binding antibodies but has subsequently become more broadly used. There are many variants of Yariv reagents which vary in the glycosyl groups on the outside of the structure, typically glucose, galactose, and mannose.
Fiona Jean McDonald is a New Zealand physiologist, professor and head of the McDonald Lab and the Department of Physiology at the University of Otago.
Arve Elvebakk is a Norwegian mycologist and professor working from the Arctic University of Norway in Tromsø who has published widely on Arctic biology, and climatology. Additionally, he collaborates with many mycologists across the world, and has published names for lichens in Australia, New Zealand, the South Pacific, and South America, and the Antarctic.
Jennifer Lee Juengel is an animal health researcher in New Zealand. She has been a Fellow of the Royal Society Te Apārangi since 2016.
Catherine Ellen Lovelock is an Australian marine ecologist, whose research focuses on coastal ecosystems. She is a professor in the School of Biological Science at the University of Queensland and 2020 Georgina Sweet Australian Laureate Fellow.
