In 1992, Canadian authorities determined that eating fish contaminated with malachite green posed a significant health risk.[6] Malachite green was classified a Class II Health Hazard. Due to its low manufacturing cost, malachite green is still used in certain countries with less restrictive laws for non aquaculture purposes. In 2005, analysts in Hong Kong found traces of malachite green in eels and fish imported from China and Taiwan. In 2006, the United States Food and Drug Administration (FDA) detected malachite green in seafood imported from China, among others, where the substance is also banned for use in aquaculture. In June 2007, the FDA blocked the importation of several varieties of seafood due to continued malachite green contamination.[7] The substance has been banned in the United States since 1983 in food-related applications. It is banned in the UK, also.[8] Animals metabolize malachite green to its leuco form. Being lipophillic (the leuco form has a log P of 5.70), the metabolite ...

Formalin, malachite green, or a mixture of them are utilized in fish culture for control of external parasites of fish and control of fungus on fish and fish eggs. Very little information is available concerning the toxicity of these compounds to fish under laboratory test conditions or the differences in sensitivity to these chemicals at various life stages. This study was designed to 1) determine the toxicity of formalin, malachite green and the mixture to four life stages of rainbow trout (Salmo gairdneri) under various laboratory test conditions, 2) determine the degradation of formalin and malachite green in water, 3) determine the effect of additive toxicity, and 4) determine the differences in sensitivity of two different lots of eggs to the chemicals. The 96-hour LC50 (lethal concentration required to produce 50% mortality) for formalin against rainbow trout in soft water ranged from 580 micrograms/liter for the eyed egg stage to 134 micrograms/liter for the fingerling stage. The 96-hour ...
The Bradford assay, a colorimetric protein assay, is based on an absorbance shift of the dye Coomassie Brilliant Blue G-250. The Coomassie Brilliant Blue G-250 dye exists in three forms: anionic (blue), neutral (green), and cationic (red).[3] Under acidic conditions, the red form of the dye is converted into its blue form, binding to the protein being assayed. If theres no protein to bind, then the solution will remain brown. The dye forms a strong, noncovalent complex with the proteins carboxyl group by van der Waals force and amino group through electrostatic interactions.[1] During the formation of this complex, the red form of Coomassie dye first donates its free electron to the ionizable groups on the protein, which causes a disruption of the proteins native state, consequently exposing its hydrophobic pockets. These pockets in the proteins tertiary structure bind non-covalently to the non-polar region of the dye via the first bond interaction (van der Waals forces) which position the ...
Leucomalachite Green ELISA [R-LMG3466] - Malachite green is a triphenylmethane dye, which is used extensively in the aquaculture industry for the treatment of fungal and protozoal infections. The toxicity of the dye increases with exposure time, temperature and concentration and has been reported to cause carcinogenesis, mutagenesis, chromosomal fractures, teratogenicity and respiratory toxicity.

The basic idea is to find the magenta value for the skintone in question. This is the major half of the hue contributor and will decide how pink the image is. Yellow is often equal to the magenta value, and is run higher for deeper tans - although it can be common for areas to have slightly less yellow than magenta or for other skintones to favour magenta over yellow. But the pleasing tan is often made from high magenta with higher yellow ratios. The cyan is the critical value for toning down the red hue and for adding definition. Starting with a value of 1/5 cyan compared to magenta, the ratio often increases to 1/3 or even 1/2 the cyan when compared to magenta. Black is usually added for shadows and is not a part of the caucasian skintone ...

Natural colours were used in the past to celebrate Holi safely by applying turmeric, sandalwood paste, extracts of flowers and leaves. As the spring-blossoming trees that once supplied the colours used to celebrate Holi have become more rare, chemically produced industrial dyes have been used to take their place in almost all of urban India. Due to the commercial availability of attractive pigments, slowly the natural colours are replaced by synthetic colours. As a result, it has caused mild to severe symptoms of skin irritation and inflammation. Lack of control over the quality and content of these colours is a problem, as they are frequently sold by vendors who do not know their origin. A 2007 study found that malachite green, a synthetic bluish-green dye used in some colours during Holi festival, was responsible for severe eye irritation in Delhi, if eyes were not washed upon exposure. Though the study found that the pigment did not penetrate through the cornea, malachite green is of concern ...

article{1179757, abstract = {Recently, novel radiochromic leucodye micelle hydrogel dosimeters were introduced in the literature. In these studies, gel measured electron depth dose profiles were compared with ion chamber depth dose data, from which it was concluded that leucocrystal violet-type dosimeters were independent of dose rate. Similar conclusions were drawn for leucomalachite green-type dosimeters, only after pre-irradiating the samples to a homogeneous radiation dose. However, in our extensive study of the radio-physical properties of leucocrystal violet- and leucomalachite green-type dosimeters, a significant dose rate dependence was found. For a dose rate variation between 50 and 400 cGy min(-1), a maximum difference of 75\% was found in optical dose sensitivity for the leucomalachite green-type dosimeter. Furthermore, the measured optical dose sensitivity of the leucomalachite green-type dosimeter was four times lower than the value previously reported in the literature. For the ...

One of the tests performed at the Department of Biologicals of the Laboratory for Medicins and Medical Devices is an assay for the detection of residual animal serum albumin (bovine serum albumin and ovalbumin) in vaccines. The method used is an immunoprecipitation test using Counter Current Electroforesis (C.C.E.). After electroforesis the precipitate of albumin and anti-albumin serum is stained by Coomassie Brilliant Blue. Traditionally the agarose-gels are visually inspected for the presence of stained precipitates using the light of a bulb shining through opal glass. This report describes the validation of a new detection technique. The agarose-gel is illuminated using two halogen lamps. Under this illumination the precipitates appear as little red lines.Using the traditional detection-method (light bulb) the detection-limit was 1 mul animal serum per litre vaccine. Using the new detection-method (halogen-lamps) the detection-limit is lowered by at least a factor 2. Furthermore, as a ...

The purpose of this study is to learn if a surgical technique called intraoperative lymphatic mapping can accurately identify the lymph node that is at greatest risk if endometrial or cervical cancer spreads to the lymph nodes.. Early cervical cancer is usually treated by removing the cervix, tissue around the cervix, and the upper vagina. If needed, the uterus is also removed. The treatment also includes removing lymph nodes from the pelvis. Endometrial cancer is usually treated by removing the cervix, uterus, fallopian tubes and ovaries.. The treatment also includes removing lymph nodes from the pelvis. ...

Pryor 1970) through the cuprite layers, allowing the copper ions to dissolve in water and reprecipitate. If the water chemistry approximates that of seawater, copper ions reprecipitate as botallackite (Cu2(OH)3Cl) (Pollard et al. 1989), which can convert in minutes or hours to either paratacamite or atacamite (alternate crystal structures of botallackite), depending on local water chemistry. Paratacamite is the more common form (Kato and Pickering 1984). If the water contains little Cl− but is in equilibrium with the atmosphere with regard to carbonate species, malachite will form. A direct solid-state transformation of cuprite to malachite is possible, while a transformation to a hydroxychloride mineral would require dissolution and precipitation (fig. 4). Malachite and hydroxychloride minerals normally precipitate from solution. If both Cl− and carbonate species are lacking, tenorite (CuO) is produced. The hydroxychlorides, atacamite and paratacamite, form in inhomogeneous layered ...
