Lithospermum Erythrorhizon
''Lithospermum erythrorhizon'', commonly called purple gromwell, red gromwell, red-root gromwell and redroot lithospermum, is a plant species in the genus ''Lithospermum''. It is called ''zǐcǎo'' () in Chinese, ''jichi'' () in Korean, and ''murasaki'' (; ) in Japanese. The dried root of ''Lithospermum erythrorhizon'' (lithospermum root or ''Lithospermi Radix'') is a Chinese herbal medicine with various antiviral and biological activities, including inhibition of human immunodeficiency virus type 1 (HIV-1). The genome sequence of ''Lithospermum erythrorhizon'' is sequenced and has facilitated the discovery of a putative retrotransposition-derived duplication event that produced a 4-hydroxybenzoate geranyltransferase gene involved in alkannin biosynthesis. Biochemistry The enzyme 4-hydroxybenzoate geranyltransferase utilizes geranyl diphosphate and 4-hydroxybenzoate to produce 3-geranyl-4-hydroxybenzoate and diphosphate. Biosynthetically, alkannin is produced in plants fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithospermum Erythrorhizon 2
''Lithospermum'' is a genus of plants belonging to the family Boraginaceae. The genus is distributed nearly worldwide, but most are native to the Americas and the center of diversity is in the southwestern United States and Mexico. Species are known generally as gromwells or stoneseeds. Taxonomy There are about 50, to 60 species in the genus.Cohen, J. I., (2012)Comparative floral development in ''Lithospermum'' (Boraginaceae) and implications for the evolution and development of heterostyly.''American Journal of Botany'' 99(5), 797–805. Some species, such as ''Lithospermum arvense'', are sometimes classified in the genus '' Buglossoides'', but that genus is subsumed into ''Lithospermum'' by works such as the ''Flora of China''. In addition, a 2009 molecular study showed that the genus ''Onosmodium'' should be included within ''Lithospermum''. Species include: *''Lithospermum arvense'' (syn. ''Buglossoides arvensis'') – field gromwell, corn gromwell *'' Lithospermum azuayen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meiji Period
The is an era of Japanese history that extended from October 23, 1868 to July 30, 1912. The Meiji era was the first half of the Empire of Japan, when the Japanese people moved from being an isolated feudal society at risk of colonization by Western powers to the new paradigm of a modern, industrialized nation state and emergent great power, influenced by Western scientific, technological, philosophical, political, legal, and aesthetic ideas. As a result of such wholesale adoption of radically different ideas, the changes to Japan were profound, and affected its social structure, internal politics, economy, military, and foreign relations. The period corresponded to the reign of Emperor Meiji. It was preceded by the Keiō era and was succeeded by the Taishō era, upon the accession of Emperor Taishō. The rapid modernization during the Meiji era was not without its opponents, as the rapid changes to society caused many disaffected traditionalists from the former samurai ...

Photobleaching
In optics, photobleaching (sometimes termed fading) is the photochemical alteration of a dye or a fluorophore molecule such that it is permanently unable to fluoresce. This is caused by cleaving of covalent bonds or non-specific reactions between the fluorophore and surrounding molecules. Such irreversible modifications in covalent bonds are caused by transition from a singlet state to the triplet state of the fluorophores. The number of excitation cycles to achieve full bleaching varies. In microscopy, photobleaching may complicate the observation of fluorescent molecules, since they will eventually be destroyed by the light exposure necessary to stimulate them into fluorescing. This is especially problematic in time-lapse microscopy. However, photobleaching may also be used prior to applying the (primarily antibody-linked) fluorescent molecules, in an attempt to quench autofluorescence. This can help improve the signal-to-noise ratio. Photobleaching may also be exploited to study ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alum
An alum () is a type of chemical compound, usually a hydrated double salt, double sulfate salt (chemistry), salt of aluminium with the general chemical formula, formula , where is a valence (chemistry), monovalent cation such as potassium or ammonium. By itself, "alum" often refers to potassium alum, with the formula . Other alums are named after the monovalent ion, such as sodium alum and ammonium alum. The name "alum" is also used, more generally, for salts with the same formula and structure, except that aluminium is replaced by another valence (chemistry), trivalent metal ion like chromium#Chromium(III), chromium, and/or sulfur is replaced by another chalcogen like selenium. The most common of these analogs is chrome alum . In most industries, the name "alum" (or "papermaker's alum") is used to refer to aluminium sulfate, , which is used for most industrial flocculation (the variable is an integer whose size depends on the amount of water absorbed into the alum).

Jūnihitoe
The , more formally known as the , is a style of formal court dress first worn in the Heian period by noble women and ladies-in-waiting at the Japanese Imperial Court. The was composed of a number of kimono-like robes, layered on top of each other, with the outer robes cut both larger and thinner to reveal the layered garments underneath. These robes were referred to as , with the innermost robe – worn as underwear against the skin – known as the . were also worn as underwear with the ; over time, the two would gradually become outerwear, with the eventually developing into the modern-day kimono. Despite the name, the varied in its exact number of layers. It also featured an (belt), though unlike modern , this was little more than a thin, cordlike length of fabric. The number of layers, and the type of layers, could alter the formality of a outfit, with some accessories, such as overcoats and a long, skirt-like train (known as the ) only worn for special, formal occasion ...

Heian Period
The is the last division of classical Japanese history, running from 794 to 1185. It followed the Nara period, beginning when the 50th emperor, Emperor Kanmu, moved the capital of Japan to Heian-kyō (modern Kyoto). means "peace" in Japanese. It is a period in Japanese history when the Chinese influences were in decline and the national culture matured. The Heian period is also considered the peak of the Japanese imperial court and noted for its art, especially poetry and literature. Two types of Japanese script emerged, including katakana, a phonetic script which was abbreviated into hiragana, a cursive alphabet with a unique writing method distinctive to Japan. This gave rise to Japan's famous vernacular literature, with many of its texts written by court women who were not as educated in Chinese compared to their male counterparts. Although the Imperial House of Japan had power on the surface, the real power was in the hands of the Fujiwara clan, a powerful aristocratic f ...

Purple
Purple is any of a variety of colors with hue between red and blue. In the RGB color model used in computer and television screens, purples are produced by mixing red and blue light. In the RYB color model historically used by painters, purples are created with a combination of red and blue pigments. In the CMYK color model used in printing, purples are made by combining magenta pigment with either cyan pigment, black pigment, or both. Purple has long been associated with royalty, originally because Tyrian purple dye, made from the mucus secretion of a species of snail, was extremely expensive in antiquity. Purple was the color worn by Roman magistrates; it became the imperial color worn by the rulers of the Byzantine Empire and the Holy Roman Empire, and later by Roman Catholic bishops. Similarly in Japan, the color is traditionally associated with the emperor and aristocracy. According to contemporary surveys in Europe and the United States, purple is the color most ofte ...

Murasaki
''Murasaki'' refers to the heroine of '' The Tale of Genji'' (), after whom the book's author, Murasaki Shikibu, was named by her contemporaries. She was a lady in waiting at the Imperial Court of Japan, around the year 1000. Murasaki Shikibu's given name remains unknown to this day. The word Shikibu is actually no name, but refers to the rank of her father, who was in the Emperor's service as provincial governor. The Name Murasaki The name remained a pseudonym, as due to court manners of the author's time (the Heian period, 794–1185), it was considered unacceptably familiar and vulgar to freely address people by either their personal or family names; within the novel, the character herself, too, is unnamed, as most of the book's characters are never identified by any name, but by their rank and title (in the case of male persons), the rank and title of their male relatives (in the case of female persons), or after the name of their habitation (in the case of the great cou ...

Pen Name
A pen name, also called a ''nom de plume'' or a literary double, is a pseudonym (or, in some cases, a variant form of a real name) adopted by an author and printed on the title page or by-line of their works in place of their real name. A pen name may be used to make the author's name more distinctive, to disguise the author's gender, to distance the author from their other works, to protect the author from retribution for their writings, to merge multiple persons into a single identifiable author, or for any of a number of reasons related to the marketing or aesthetic presentation of the work. The author's real identity may be known only to the publisher or may become common knowledge. Etymology The French-language phrase is occasionally still seen as a synonym for the English term "pen name", which is a "back-translation" and originated in England rather than France. H. W. Fowler and F. G. Fowler, in ''The King's English'' state that the term ''nom de plume'' evolv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Language
is spoken natively by about 128 million people, primarily by Japanese people and primarily in Japan, the only country where it is the national language. Japanese belongs to the Japonic or Japanese- Ryukyuan language family. There have been many attempts to group the Japonic languages with other families such as the Ainu, Austroasiatic, Koreanic, and the now-discredited Altaic, but none of these proposals has gained widespread acceptance. Little is known of the language's prehistory, or when it first appeared in Japan. Chinese documents from the 3rd century AD recorded a few Japanese words, but substantial Old Japanese texts did not appear until the 8th century. From the Heian period (794–1185), there was a massive influx of Sino-Japanese vocabulary into the language, affecting the phonology of Early Middle Japanese. Late Middle Japanese (1185–1600) saw extensive grammatical changes and the first appearance of European loanwords. The basis of the standard dialect moved f ...

Ombré
''Ombré'' (literally "shaded" in French) is the blending of one color hue to another, usually moving tints and shades from light to dark. It has become a popular feature for hair coloring, nail art, and even baking, in addition to its uses in home decorating and graphic design. In contrast to ''ombré, sombré'' is a much softer and gradual shading of one color to another. In fashion History Using shading or creating an ''ombré'' effect is ubiquitous. For instance in fabric printing, a special printing block, called a "rainbowed" block, was used in the early 19th century to produce textiles with graduated color designs. ''Ombré'' as a textile treatment came back into fashion in around 1840 and was used throughout the 19th century. In machine embroidery, an ''ombré'' effect was achieved by dyeing the threads in graded colors beforehand. 21st century “Ombré” as a hair-coloring technique had been popularized in 2000 when the singer Aaliyah had her hair dyed in a subtle ...
