Okibacterium fritillariae gen. nov., sp. nov., a novel genus of the family Microbacteriaceae. (1/9)
Okibacterium fritillariae gen. nov., sp. nov. (type strain VKM Ac-2059T = IFO 16404T) is proposed for aerobic, oxidase- and catalase-positive, coryneform bacteria isolated from seeds of Fritillaria ruthenica Wikstr. and Clematis recta L. Strains of the new genus form a distinct branch within the phylogenetic cluster composed of members of the family Microbacteriaceae and are characterized by B-type peptidoglycan containing amino acids glycine, glutamate, homoserine, alanine and lysine, the glycolyl type of muramic acid, the major menaquinones MK-10 and MK-11, the principal phospholipids phosphatidylglycerol and diphosphatidylglycerol, and a DNA G+C content of approximately 67 mol %. (+info)Growth habit and mechanical architecture of the sand dune-adapted climber Clematis flammula var. maritima L. (2/9)
Clematis flammula var. maritima is a woody lianoid plant that grows on coastal sand dunes in the Mediterranean region. Older perennial stems are present as extensive underground axes. These generate surface growth of shorter-lived stems producing monospecific trellises above the surface of the sand. Despite its sand dune habitat and shortage of host support plants, this variety of Clematis shows mechanical characteristics during growth that are closely comparable with those of scandent woody lianas. A significant decrease in the value of structural Young's modulus is observed from the aerial trellis-forming shoots (1.619 +/- 0.492 GN m(-2)) to emergent axes (0.855 +/- 0.253 GN m(-2)) and underground woody stems (0.470 +/- 0.113 GN m(-2)). Biomechanical and developmental observations indicate that most emergent branches are optimized geometrically and mechanically in relation to their points of emergence from the sand, with increases in structural Young's modulus and the second moment of area around the surface of the sand. Lianoid plants, physiologically capable of withstanding sand dune environments, might represent acceptable natural or introduced species for dune stabilization and conservation.

A simple, specific and reliable high performance liquid chromatography (HPLC) method has been developed and validated for study of fingerprint chromatograms of extracts from the whole plant of Clematis huchouensis Tamura (CHT) for quality control of a traditional Chinese medicinal (TCM) herb. An Agilent C18 column was used to separate extracts in this protocol and detection was made by ultraviolet absorbance at 340 nm. The column temperature was maintained at 25 degrees C. A mobile phase consisting of (a) water (with 30 mM KH2PO4) and (b) CH3CN, (c) CH3OH was found to be suitable for this separation at a flow rate of 0.8 microl min(-1) with gradient elution. Under the described conditions, a fingerprint profile of 8 compounds was collected within 35 min, which made the HPLC method unique and interesting. The fingerprint chromatograms had good stability, precision and reproducibility. Moreover, eco-climatic (habitat) effects were studied by comparison of fingerprint chromatograms obtained from extracts of CHT collected from two habitats, with rutin as a reference marker peak. The protocol developed is quite suitable for differentiation of extracts of CHT and can be used as a quality control method for this herb and a model for other herbal drugs.

(+info)'Clematis' is not a medical term, it is a genus of plants including over 300 species, some of which (like Clematis vitalba) are known to have minor medicinal uses such as topical applications for skin irritations and vasodilatory effects, but they are not widely used in modern medicine.
'Clematis' is a term that refers to a genus of woody climbing vines and shrubs, primarily found in the northern hemisphere. These plants are known for their beautiful and showy flowers, which come in a variety of colors, shapes, and sizes. While 'Clematis' is not a medical term, it is possible that you may have been looking for "clematide," which is a type of protein found in some animals and has been studied in the context of cancer research. However, without more context, I cannot be sure.
