Eucryphia
''Eucryphia'' is a small genus of trees and large shrubs native to the south temperate regions of South America and coastal eastern Australia, mainly Tasmania. Sometimes placed in a family of their own, the Eucryphiaceae, more recent classifications place them in the Cunoniaceae. There are seven species, two in South America and five in Australia, and several named hybrids. Description They are mostly evergreen though one species (''E. glutinosa'') is usually deciduous. The leaves are opposite, and either simple or pinnate with 3-13 leaflets. The flowers are produced in late summer or autumn, are showy and sweetly scented, 3–6 cm diameter, with four creamy-white petals, and numerous stamens and styles. The fruit is a woody capsule 1-1.5 cm long containing several seeds, and maturing in 12–15 months. Etymology The generic name ''Eucryphia'' is composed of two parts, namely ''eu-'' and ''-cryphia''. The Greek ευ-κρυφαιος means well-covered and refers t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drug Resistance
Drug resistance is the reduction in effectiveness of a medication such as an antimicrobial or an antineoplastic in treating a disease or condition. The term is used in the context of resistance that pathogens or cancers have "acquired", that is, resistance has evolved. Antimicrobial resistance and antineoplastic resistance challenge clinical care and drive research. When an organism is resistant to more than one drug, it is said to be multidrug-resistant. The development of antibiotic resistance in particular stems from the drugs targeting only specific bacterial molecules (almost always proteins). Because the drug is ''so'' specific, any mutation in these molecules will interfere with or negate its destructive effect, resulting in antibiotic resistance. Furthermore, there is mounting concern over the abuse of antibiotics in the farming of livestock, which in the European Union alone accounts for three times the volume dispensed to humans – leading to development of super-resi ...

Flacherie
Flacherie (literally: "flaccidness") is a disease of silkworms, caused by silkworms eating infected or contaminated mulberry leaves. Flacherie infected silkworms look weak and can die from this disease. Silkworm larvae that are about to die from Flacherie are a dark brown. There are two kinds of flacherie: essentially, infectious (viral) flacherie and noninfectious (''touffée'') flacherie. Both are technically a lethal diarrhea. Touffée flacherie is caused by heat waves. Viral flacherie is ultimately caused by infection with ''Bombyx mori'' infectious flacherie virus (BmIFV, Iflaviridae), ''Bombyx mori'' densovirus (BmDNV, Parvoviridae) or ''Bombyx mori'' cypovirus 1 (BmCPV-1, Reoviridae). This either alone or in combination with bacterial infection destroys the gut tissue. Bacterial pathogens contributing to infectious flaccherie are ''Serratia marcescens'', and species of ''Streptococcus ''Streptococcus'' is a genus of gram-positive ' (plural ) or spherical bacteri ...

Assam
Assam (; ) is a state in northeastern India, south of the eastern Himalayas along the Brahmaputra and Barak River valleys. Assam covers an area of . The state is bordered by Bhutan and Arunachal Pradesh to the north; Nagaland and Manipur to the east; Meghalaya, Tripura, Mizoram and Bangladesh to the south; and West Bengal to the west via the Siliguri Corridor, a wide strip of land that connects the state to the rest of India. Assamese and Boro are the official languages of Assam, while Bengali is an additional official language in the Barak Valley. Assam is known for Assam tea and Assam silk. The state was the first site for oil drilling in Asia. Assam is home to the one-horned Indian rhinoceros, along with the wild water buffalo, pygmy hog, tiger and various species of Asiatic birds, and provides one of the last wild habitats for the Asian elephant. The Assamese economy is aided by wildlife tourism to Kaziranga National Park and Manas National Park, which are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muga Silk
Muga silk is a variety of wild silk geographically tagged to the state of Assam in India. The silk is known for its extreme durability and has a natural yellowish-golden tint with a shimmering, glossy texture. It was previously reserved for the use of royalty. In the Brahmaputra Valley, the larvae of the Assam silkmoth feed on aromatic ''Som'' ('' Machilus bombycina'') and ''Sualu'' ('' Litsea polyantha'') leaves. Muga silk can be dyed after bleaching. This silk can be hand-washed with its lustre increasing after every wash. Muga silk, like other Assam silks, is used in products like saris, mekhalas and chadors. History Sericulture in Assam is an ancient industry without a precise time of origin. Assam was well known for the production of high quality silk since ancient times. The craft of weaving goes along with the production of silk. It grew to such sophistication in Assam that it was known all over India and abroad. The first reference to Assam silk was probably in Valm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antheraea Assamensis
''Antheraea assamensis'', known as the muga silkworm as a larva and Assam silk moth as an adult, is a moth of the family Saturniidae. The species was first described by Johann Wilhelm Helfer in 1837. It is found in Assam in northeast India where 99% of its production occurs. The larva feed on ''Cinnamomum'', ''Laurus'', ''Litsea'', ''Carpinus'', ''Persea'', ''Magnolia'', ''Michelia'', ''Quercus'', ''Sarcostemma'' and ''Symplocos''. Its silk, one of the varieties of tussar silk, has a glossy golden hue which improves with age and washing. It is never bleached or dyed and is stain resistant. It was reserved for the exclusive use of elites in Assam. Like other silk moths, the female has a larger abdomen and slender antennae when compared to males. The larvae are vibrantly coloured and are monophagous as other silk moths. In 2015, Adarsh Gupta K of Nagaraju's research team at Centre for DNA Fingerprinting and Diagnostics, Hyderabad, India, discovered the complete sequence and the pro ...

Western World
The Western world, also known as the West, primarily refers to the various nations and state (polity), states in the regions of Europe, North America, and Oceania.Western Civilization Our Tradition; James Kurth; accessed 30 August 2011 The Western world is also known as the Occident (from the Latin word ''occidēns'' "setting down, sunset, west") in contrast to the Eastern world known as the Orient (from the Latin word ''oriēns'' "origin, sunrise, east"). Following the Discovery of America in 1492, the West came to be known as the "world of business" and trade; and might also mean the Northern half of the North–South divide, the countries of the ''Global North'' (often equated with capitalist Developed country, developed countries).

Clostridioides Difficile Infection
''Clostridioides difficile'' infection (CDI or C-diff), also known as ''Clostridium difficile'' infection, is a symptomatic infection due to the bacterial spores, spore-forming bacterium ''Clostridioides difficile''. Symptoms include watery diarrhea, fever, nausea, and abdominal pain. It makes up about 20% of cases of antibiotic-associated diarrhea. Antibiotics can contribute to detrimental changes in gut microbiota; specifically, they decrease short-chain fatty acid absorption which results in osmotic, or watery, diarrhea. Complications may include colitis#Infectious, pseudomembranous colitis, toxic megacolon, perforation of the colon, and sepsis. ''Clostridioides difficile'' infection is spread by bacterial spores found within feces. Surfaces may become contaminated with the spores with further spread occurring via the hands of healthcare workers. Risk factors for infection include antibiotic or proton pump inhibitor use, hospitalization, other health problems, and older a ...

Cyanobacteria
Cyanobacteria (), also known as Cyanophyta, are a phylum of gram-negative bacteria that obtain energy via photosynthesis. The name ''cyanobacteria'' refers to their color (), which similarly forms the basis of cyanobacteria's common name, blue-green algae, although they are not usually scientifically classified as algae. They appear to have originated in a freshwater or terrestrial environment. Sericytochromatia, the proposed name of the paraphyletic and most basal group, is the ancestor of both the non-photosynthetic group Melainabacteria and the photosynthetic cyanobacteria, also called Oxyphotobacteria. Cyanobacteria use photosynthetic pigments, such as carotenoids, phycobilins, and various forms of chlorophyll, which absorb energy from light. Unlike heterotrophic prokaryotes, cyanobacteria have internal membranes. These are flattened sacs called thylakoids where photosynthesis is performed. Phototrophic eukaryotes such as green plants perform photosynthesis in plast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacteriophage
A bacteriophage (), also known informally as a ''phage'' (), is a duplodnaviria virus that infects and replicates within bacteria and archaea. The term was derived from "bacteria" and the Greek φαγεῖν ('), meaning "to devour". Bacteriophages are composed of proteins that encapsulate a DNA or RNA genome, and may have structures that are either simple or elaborate. Their genomes may encode as few as four genes (e.g. MS2) and as many as hundreds of genes. Phages replicate within the bacterium following the injection of their genome into its cytoplasm. Bacteriophages are among the most common and diverse entities in the biosphere. Bacteriophages are ubiquitous viruses, found wherever bacteria exist. It is estimated there are more than 1031 bacteriophages on the planet, more than every other organism on Earth, including bacteria, combined. Viruses are the most abundant biological entity in the water column of the world's oceans, and the second largest component of biom ...

Molecular Evolution
Molecular evolution is the process of change in the sequence composition of cellular molecules such as DNA, RNA, and proteins across generations. The field of molecular evolution uses principles of evolutionary biology and population genetics to explain patterns in these changes. Major topics in molecular evolution concern the rates and impacts of single nucleotide changes, neutral evolution vs. natural selection, origins of new genes, the genetic nature of complex traits, the genetic basis of speciation, evolution of development, and ways that evolutionary forces influence genomic and phenotypic changes. History The history of molecular evolution starts in the early 20th century with comparative biochemistry, and the use of "fingerprinting" methods such as immune assays, gel electrophoresis and paper chromatography in the 1950s to explore homologous proteins. The field of molecular evolution came into its own in the 1960s and 1970s, following the rise of molecular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
