Aster is a genus of perennial flowering plants in the family Asteraceae. Its circumscription has been narrowed, and it now encompasses around 170 species, all but one of which are restricted to Eurasia; many species formerly in Aster are now in other genera of the tribe Astereae. Aster amellus is the type species of the genus and the family Asteraceae.
Heracleum is a genus of biennial and perennial herbs in the carrot family Apiaceae. They are found throughout the temperate northern hemisphere and in high mountains as far south as Ethiopia. Common names for the genus or its species include hogweed and cow parsnip.
Phytoplasmas are obligate intracellular parasites of plant phloem tissue and of the insect vectors that are involved in their plant-to-plant transmission. Phytoplasmas were discovered in 1967 by Japanese scientists who termed them mycoplasma-like organisms. Since their discovery, phytoplasmas have resisted all attempts at in vitro culture in any cell-free medium; routine cultivation in an artificial medium thus remains a major challenge. Phytoplasmas are characterized by the lack of a cell wall, a pleiomorphic or filamentous shape, a diameter normally less than 1 μm, and a very small genome.
Meconopsis is a genus of flowering plants in the poppy family Papaveraceae. It was created by French botanist Viguier in 1814 for the species known by the common name Welsh poppy, which Carl Linnaeus had described as Papaver cambricum. The genus name means "poppy-like". Himalayan species discovered later were also placed in Meconopsis. In the 21st century, it was discovered that the Himalayan species were less closely related to the Welsh poppy, which has been restored to Papaver. All species now placed in Meconopsis are native to the Himalayas and surrounding regions. They have attractive, usually blue flowers.
Anaphalis is a genus of herbaceous and woody flowering plants within the family Asteraceae, whose members are commonly known by the name pearl or pearly everlasting. There are around 110 species with the vast majority being native to central and southern Asia. There is one species native to North America that is fairly well known and popular in cultivation, namely the western pearly everlasting.
Intracerebral hemorrhage (ICH), also known as cerebral bleed, intraparenchymal bleed, and hemorrhagic stroke, or haemorrhagic stroke, is a sudden bleeding into the tissues of the brain, into its ventricles, or into both. It is one kind of bleeding within the skull and one kind of stroke. Symptoms can include headache, one-sided weakness, vomiting, seizures, decreased level of consciousness, and neck stiffness. Often, symptoms get worse over time. Fever is also common.
Pinocembrin is a flavanone, a type of flavonoid. It is an antioxidant found in damiana, honey, fingerroot, and propolis.
Coptisine is an alkaloid found in Chinese goldthread, greater celandine, and opium. Famous for the bitter taste that it produces, it is used in Chinese herbal medicine along with the related compound berberine for digestive disorders caused by bacterial infections.
The hok/sok system is a postsegregational killing mechanism employed by the R1 plasmid in Escherichia coli. It was the first type I toxin-antitoxin pair to be identified through characterisation of a plasmid-stabilising locus. It is a type I system because the toxin is neutralised by a complementary RNA, rather than a partnered protein.
Neurogenic locus notch homolog protein 1(Notch 1) is a protein encoded in humans by the NOTCH1 gene. Notch 1 is a single-pass transmembrane receptor.
The Tiaojishan Formation is a geological formation in Hebei and Liaoning, People's Republic of China, dating to the middle-late Jurassic period. It is known for its exceptionally preserved fossils, including those of plants, insects and vertebrates. It is made up mainly of pyroclastic rock interspersed with basic volcanic and sedimentary rocks. Previously, the Tiaojishan Formation was grouped together with the underlying Haifanggou Formation as a single "Lanqi Formation." The Tiaojishan Formation forms a key part of the Yanliao Biota assemblage.
Dolomiaea is a genus of Asian flowering plants in the family Asteraceae.
CRISPR-Cas design tools are computer software platforms and bioinformatics tools used to facilitate the design of guide RNAs (gRNAs) for use with the CRISPR/Cas gene editing system.
Prunus subg. Cerasus is a subgenus of Prunus. Species of the subgenus have a single winter bud per axil. The flowers are usually in small corymbs or umbels of several together, but some species have short racemes. The fruit is a drupe and has no obvious groove along the side. The subgenus is native to the temperate regions of the Northern Hemisphere, with two species in North America, four in Europe, two in North Africa, and the remainder in Asia.
Severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) is a strain of coronavirus that causes COVID-19, the respiratory illness responsible for the ongoing COVID-19 pandemic. The virus previously had a provisional name, 2019 novel coronavirus (2019-nCoV), and has also been called human coronavirus 2019. First identified in the city of Wuhan, Hubei, China, the World Health Organization declared the outbreak a Public Health Emergency of International Concern on 30 January 2020, and a pandemic on 11 March 2020. SARS‑CoV‑2 is a positive-sense single-stranded RNA virus that is contagious in humans.
Melanoseris is a genus of flowering plants belonging to the family Asteraceae.
Omphalogramma is a genus of flowering plants belonging to the family Primulaceae.
The Thyroid Feedback Quantile-based Index (TFQI) is a calculated parameter for thyrotropic pituitary function. It was defined to be more robust to distorted data than established markers including Jostel's TSH index (JTI) and the thyrotroph thyroid hormone sensitivity index (TTSI).
Beiguornis is a genus of bohaiornithid bird from the Early Cretaceous Longjiang Formation of Inner Mongolia, China. The genus contains a single species, Beiguornis khinganensis. Beiguornis is the first and only enantiornithine bird known from the Longjiang Formation. In the phylogenetic analysis conducted by the describing authors, Beiguornis formed a monophyletic group with the bohaiornithids Sulcavis and Zhouornis.
