Pteleopsis Myrtifolia
''Pteleopsis myrtifolia'' ('Ptelea' = elm, 'opsis' = resembling, 'myrtifolia' = leaves like those of the myrtle) is one of some 10 African species in this genus in the family of Combretaceae. It is the only ''Pteleopsis'' species to occur in Southern Africa. Its flowers are strongly scented and perceived by humans to be either 'honey-like' or 'cloying' or even 'stinky'. The timber is red, hard and durable, and used for furniture and construction. This is a dense, often multi-stemmed semi-deciduous small tree with a drooping habit up to 20 m tall. Bark is greyish-pink, and smooth, net-like in appearance. Leaves are opposite and simple, 10–95 mm x 6–35 mm, narrowly elliptical with acute apex and base; surface glabrous and occasionally glossy above; margins entire and may be wavy. Petiole is often hairy. Inflorescence axillary and some 45 mm long. Ellipsoid fruit with 2 or 3 wings, 10–25 mm x 5–17 mm. It is found on rocky hillsides and stony outcrop ...

Cryptococcus Neoformans
''Cryptococcus neoformans'' is an encapsulated yeast belonging to the class Tremellomycetes and an obligate aerobe that can live in both plants and animals. Its teleomorph is a filamentous fungus, formerly referred to ''Filobasidiella neoformans''. In its yeast state, it is often found in bird excrement. ''Cryptococcus neoformans'' can cause disease in apparently immunocompetent, as well as immunocompromised, hosts. Classification ''Cryptococcus neoformans'' has undergone numerous nomenclature revisions since its first description in 1895. It formerly contained two varieties: ''C. neoformans ''var.'' neoformans'' and ''C. neoformans '' var.'' grubii''. A third variety, ''C. neoformans ''var.'' gattii'', was later defined as a distinct species, ''Cryptococcus gattii''. The most recent classification system divides these varieties into seven species. ''C. neoformans'' refers to ''C. neoformans '' var.'' grubii''. A new species name, ''Cryptococcus deneoformans'', is used for the f ...

Candida Krusei
''Candida krusei'' is a budding yeast (a species of fungus) involved in chocolate production. ''Candida krusei'' is an emerging fungal nosocomial pathogen primarily found in the immunocompromised and those with hematological malignancies. It has natural resistance to fluconazole, a standard antifungal agent. It is most often found in patients who have had prior fluconazole exposure, sparking debate and conflicting evidence as to whether fluconazole should be used prophylactically. Mortality due to ''C. krusei'' fungemia is much higher than the more common ''C. albicans''. Other '' Candida'' species that also fit this profile are ''C. parapsilosis'', ''C. glabrata'', ''C. tropicalis'', ''C. guillermondii'' and ''C. rugosa''. ''Candida krusei'' is the anamorph name; the teleomorph name for the same organism is ''Pichia kudriavzevii.'' The International Commission on the Taxonomy of Fungi (ICTF) and the Nomenclature Committee for Fungi (NCF) have proposed revising the standard na ...

Candida Glabrata
''Candida glabrata'' is a species of haploid yeast of the genus ''Candida'', previously known as ''Torulopsis glabrata''. Despite the fact that no sexual life cycle has been documented for this species, ''C. glabrata'' strains of both mating types are commonly found. C''. glabrata'' is generally a commensal of human mucosal tissues, but in today's era of wider human immunodeficiency from various causes (for example, therapeutic immunomodulation, longer survival with various comorbidities such as diabetes, and HIV infection), ''C. glabrata'' is often the second or third most common cause of candidiasis as an opportunistic pathogen. Infections caused by ''C. glabrata'' can affect the urogenital tract or even cause systemic infections by entrance of the fungal cells in the bloodstream ( Candidemia), especially prevalent in immunocompromised patients. Clinical relevance ''Candida glabrata'' is of special relevance in nosocomial infections due to its innately high resistance to antifu ...

Methanol
Methanol (also called methyl alcohol and wood spirit, amongst other names) is an organic chemical and the simplest aliphatic alcohol, with the formula C H3 O H (a methyl group linked to a hydroxyl group, often abbreviated as MeOH). It is a light, volatile, colourless, flammable liquid with a distinctive alcoholic odour similar to that of ethanol (potable alcohol). A polar solvent, methanol acquired the name wood alcohol because it was once produced chiefly by the destructive distillation of wood. Today, methanol is mainly produced industrially by hydrogenation of carbon monoxide. Methanol consists of a methyl group linked to a polar hydroxyl group. With more than 20 million tons produced annually, it is used as a precursor to other commodity chemicals, including formaldehyde, acetic acid, methyl tert-butyl ether, methyl benzoate, anisole, peroxyacids, as well as a host of more specialised chemicals. Occurrence Small amounts of methanol are present in normal, healthy hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enterococcus Faecalis
''Enterococcus faecalis'' – formerly classified as part of the group D ''Streptococcus'' system – is a Gram-positive, commensal bacterium inhabiting the gastrointestinal tracts of humans. Like other species in the genus ''Enterococcus'', ''E. faecalis'' is found in healthy humans and can be used as a probiotic. The probiotic strains such as Symbioflor1 and EF-2001 are characterized by the lack of specific genes related to drug resistance and pathogenesis. As an opportunistic pathogen, ''E. faecalis'' can cause life-threatening infections, especially in the nosocomial (hospital) environment, where the naturally high levels of antibiotic resistance found in ''E. faecalis'' contribute to its pathogenicity. ''E. faecalis'' has been frequently found in reinfected, root canal-treated teeth in prevalence values ranging from 30% to 90% of the cases. Re-infected root canal-treated teeth are about nine times more likely to harbor ''E. faecalis'' than cases of primary infections. Physi ...

Escherichia Coli
''Escherichia coli'' (),Wells, J. C. (2000) Longman Pronunciation Dictionary. Harlow ngland Pearson Education Ltd. also known as ''E. coli'' (), is a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus ''Escherichia'' that is commonly found in the lower intestine of warm-blooded organisms. Most ''E. coli'' strains are harmless, but some serotypes ( EPEC, ETEC etc.) can cause serious food poisoning in their hosts, and are occasionally responsible for food contamination incidents that prompt product recalls. Most strains do not cause disease in humans and are part of the normal microbiota of the gut; such strains are harmless or even beneficial to humans (although these strains tend to be less studied than the pathogenic ones). For example, some strains of ''E. coli'' benefit their hosts by producing vitamin K2 or by preventing the colonization of the intestine by pathogenic bacteria. These mutually beneficial relationships between ''E. col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taraxerol
Taraxerol is a naturally-occurring pentacyclic triterpenoid. It exists in various higher plants, including ''Taraxacum officinale'' (Asteraceae), ''Alnus glutinosa'' (Betulaceae), ''Litsea dealbata'' (Lauraceae), ''Skimmia spp.'' (Rutaceae), ''Dorstenia spp.'' (Moraceae), ''Maytenus spp.'' (Celastraceae), and ''Alchornea latifolia'' ( Euphobiaceae). Taraxerol was named "alnulin" when it was first isolated in 1923 from the bark of the grey alder (''Alnus incana'' L.) by Zellner and Röglsperger. It also had the name "skimmiol" when Takeda and Yosiki isolated it from ''Skimmia'' (Rutaceae). A large number of medicinal plants are known to have this compound in their leaves, roots or seed oil. Chemistry Structure Taraxerol is an oleanan-3-ol with an alpha-methyl substituent at position 13, a missing methyl group at position 14, and a double bond between 14 and 15. The dominant biological stereoisomer in plant leaves and in sediments has the taraxer-14-en-3β-ol configuration. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diospyros Zombensis
''Diospyros'' is a genus of over 700 species of deciduous and evergreen trees and shrubs. The majority are native to the tropics, with only a few species extending into temperate regions. Individual species valued for their hard, heavy, dark timber, are commonly known as ebony trees, while others are valued for their fruit and known as persimmon trees. Some are useful as ornamentals and many are of local ecological importance. Species of this genus are generally dioecious, with separate male and female plants. Taxonomy and etymology The generic name ''Diospyros'' comes from a Latin name for the Caucasian persimmon ('' D. lotus''), derived from the Greek διόσπυρος : dióspyros, from ''diós'' () and ''pyrós'' (). The Greek name literally means " Zeus's wheat" but more generally intends "divine food" or "divine fruit". Muddled translations sometimes give rise to curious and inappropriate interpretations such as " God's pear" and "Jove's fire". The genus is a ...
