Effects of oxidizing adulterants on detection of 11-nor-delta9-THC-9-carboxylic acid in urine. (1/14)
Bleach, nitrite, chromate, and hydrogen peroxide-peroxidase are effective urine adulterants used by the illicit drug users to conceal marijuana-positive results. Methods for detecting nitrite and chromate are available. Effects of other oxidizing agents that could possibly be used as adulterants and are difficult to detect or measure are presented in this report. Urine samples containing 40 ng/mL of 11-nor-delta9-THC-9-carboxylic acid (THC-acid) were treated with 10 mmol/L of commonly available oxidizing agents. Effects of horseradish peroxidase of activity 10 unit/mL and extracts from 2.5 g of red radish (Raphanus sativus, Radicula group), horseradish (Armoracia rusticana), Japanese radish (Raphanus sativus, Daikon group), and black mustard seeds (Brassica nigra), all with 10 mmol/L of hydrogen peroxide, were also examined. After 5 min, 16 h and 48 h of exposure at room temperature (23 degrees C) the specimens were tested by a gas chromatographic-mass spectrometric method for THC-acid. A control group treated with sodium hydrosulfite to reduce the oxidants, was also tested to investigate the effect of oxidizing agents on THC-acid in the extraction method. THC-acid was lost completely in the extraction method when treated with chromate, nitrite, oxone, and hydrogen peroxide/ferrous ammonium sulfate (Fenton's reagent). Some losses were also observed with persulfate and periodate (up to 25%). These oxidants, and other oxidizing agents like permanganate, periodate, peroxidase, and extracts from red radish, horseradish, Japanese radish and black mustard seeds destroyed most of the THC-acid (> 94%) within 48 h of exposure. Chlorate, perchlorate, iodate, and oxychloride under these conditions showed little or no effect. Complete loss was observed when THC-acid was exposed to 50 mmol/L of oxychloride for 48 h. Several oxidizing adulterants that are difficult to test by the present urine adulterant testing methods showed considerable effects on the destruction of THC-acid. The time and temperature for these effects were similar to those used by most laboratories to collect and test specimens. In several cases, the loss of THC-acid was > 94%.

BACKGROUND AND AIMS: Native horseradish (Armoracia rusticana) peroxidase, HRP (EC 1.11.1.7), isoenzyme C is synthesized with N-terminal and C-terminal peptide extensions, believed to be associated with protein targeting. This study aimed to explore the specific functions of these extensions, and to generate transgenic plants with expression patterns suitable for exploring the role of peroxidase in plant development and defence. METHODS: Transgenic Nicotiana tabacum (tobacco) plants expressing different versions of a synthetic horseradish peroxidase, HRP, isoenzyme C gene were constructed. The gene was engineered to include additional sequences coding for either the natural N-terminal or the C-terminal extension or both. These constructs were placed under the control of a constitutive promoter (CaMV-35S) or the tobacco RUBISCO-SSU light inducible promoter (SSU) and introduced into tobacco using Agrobacterium-mediated transformation. To study the effects of the N- and C-terminal extensions, the localization of recombinant peroxidase was determined using biochemical and molecular techniques. KEY RESULTS: Transgenic tobacco plants can exhibit a ten-fold increase in peroxidase activity compared with wild-type tobacco levels, and the majority of this activity is located in the symplast. The N-terminal extension is essential for the production of high levels of recombinant protein, while the C-terminal extension has little effect. Differences in levels of enzyme activity and recombinant protein are reflected in transcript levels. CONCLUSIONS: There is no evidence to support either preferential secretion or vacuolar targeting of recombinant peroxidase in this heterologous expression system. This leads us to question the postulated targeting roles of these peptide extensions. The N-terminal extension is essential for high level expression and appears to influence transcript stability or translational efficiency. Plants have been generated with greatly elevated cytosolic peroxidase activity, and smaller increases in apoplastic activity. These will be valuable for exploring the role of these enzymes in stress amelioration and plant development. (+info)Distribution and Translocation of 141Ce (III) in Horseradish. (3/14)
BACKGROUND AND AIMS: Rare earth elements (REEs) are used in agriculture and a large amount of them contaminate the environment and enter foods. The distribution and translocation of (141)Ce (III) in horseradish was investigated in order to help understand the biochemical behaviour and toxic mechanism of REEs in plants. METHODS: The distribution and translocation of (141)Ce (III) in horseradish were investigated using autoradiography, liquid scintillation counting (LSC) and electron microscopic autoradiography (EMARG) techniques. The contents of (141)Ce (III) and nutrient elements were analysed using an inductively coupled plasma-atomic emission spectrometer (ICP-AES). RESULTS: The results from autoradiography and LSC indicated that (141)Ce (III) could be absorbed by horseradish and transferred from the leaf to the leaf-stalk and then to the root. The content of (141)Ce (III) in different parts of horseradish was as follows: root > leaf-stalk > leaf. The uptake rates of (141)Ce (III) in horseradish changed with the different organs and time. The content of (141)Ce (III) in developing leaves was greater than that in mature leaves. The results from EMARG indicated that (141)Ce (III) could penetrate through the cell membrane and enter the mesophyll cells, being present in both extra- and intra-cellular deposits. The contents of macronutrients in horseradish were decreased by (141)Ce (III) treatment. CONCLUSIONS: (141)Ce (III) can be absorbed and transferred between organs of horseradish with time, and the distribution was found to be different at different growth stages. (141)Ce (III) can enter the mesophyll cells via apoplast and symplast channels or via plasmodesmata. (141)Ce (III) can disturb the metabolism of macronutrients in horseradish.

(+info)'Armoracia' is the genus name for a type of plant commonly known as horseradish. It belongs to the family Brassicaceae, which also includes vegetables such as broccoli, cabbage, and mustard greens. The root of the horseradish plant is used as a spice or condiment due to its pungent flavor, which is caused by the release of volatile oils when the root is grated or crushed.
Horseradish has been used in traditional medicine for various purposes, such as treating respiratory infections and promoting digestion. However, it is important to note that while some studies suggest potential health benefits of horseradish, more research is needed to confirm its effectiveness and safety. As with any medication or supplement, it is recommended to consult with a healthcare professional before using horseradish for medicinal purposes.
Horseradish peroxidase (HRP) is not a medical term, but a type of enzyme that is derived from the horseradish plant. In biological terms, HRP is defined as a heme-containing enzyme isolated from the roots of the horseradish plant (Armoracia rusticana). It is widely used in molecular biology and diagnostic applications due to its ability to catalyze various oxidative reactions, particularly in immunological techniques such as Western blotting and ELISA.
HRP catalyzes the conversion of hydrogen peroxide into water and oxygen, while simultaneously converting a variety of substrates into colored or fluorescent products that can be easily detected. This enzymatic activity makes HRP a valuable tool in detecting and quantifying specific biomolecules, such as proteins and nucleic acids, in biological samples.
Peroxidases are a group of enzymes that catalyze the oxidation of various substrates using hydrogen peroxide (H2O2) as the electron acceptor. These enzymes contain a heme prosthetic group, which plays a crucial role in their catalytic activity. Peroxidases are widely distributed in nature and can be found in plants, animals, and microorganisms. They play important roles in various biological processes, including defense against oxidative stress, lignin degradation, and host-pathogen interactions. Some common examples of peroxidases include glutathione peroxidase, which helps protect cells from oxidative damage, and horseradish peroxidase, which is often used in laboratory research.
Product labeling, in the context of medicine or healthcare, refers to the information that is required by law to be present on the packaging of a pharmaceutical product or medical device. This information typically includes:
1. The name of the product, often with an active ingredient listed separately.
2. A description of what the product is used for (indications).
3. Dosage instructions and route of administration.
4. Warnings about potential side effects, contraindications, and precautions.
5. The name and address of the manufacturer or distributor.
6. The expiration date or storage conditions, if applicable.
7. Any other relevant information, such as whether the product is subject to additional monitoring.
The purpose of product labeling is to provide accurate and standardized information to healthcare professionals and patients about the safe and effective use of a medical product. It helps to ensure that the product is used appropriately, reducing the risk of adverse events or misuse.
Guaiacol is not a medical term per se, but it is a chemical compound with potential applications in the medical field. Here's a general definition:
Guaiacol (also known as 2-methoxyphenol) is an organic compound that belongs to the class of phenols. It is a colorless or slightly yellow oily liquid with a characteristic smoky odor, and it is soluble in alcohol and ether but only sparingly soluble in water. Guaiacol occurs naturally in the smoke of wood fires and is also found in certain plants, such as guaiacum and creosote bush. It has antimicrobial properties and is used in some medical and industrial applications, including as a precursor for the synthesis of other chemicals.
Lactoperoxidase is a type of peroxidase enzyme that is present in various secretory fluids, including milk, saliva, and tears. In milk, lactoperoxidase plays an important role in the natural defense system by helping to protect against microbial growth. It does this by catalyzing the oxidation of thiocyanate ions (SCN-) in the presence of hydrogen peroxide (H2O2) to produce hypothiocyanite (OSCN-), which is a potent antimicrobial agent.
Lactoperoxidase is a glycoprotein with a molecular weight of approximately 78 kDa, and it is composed of four identical subunits, each containing a heme group that binds to the hydrogen peroxide molecule during the enzymatic reaction. Lactoperoxidase has been studied for its potential therapeutic applications in various fields, including oral health, food preservation, and wound healing.
Hydrogen peroxide (H2O2) is a colorless, odorless, clear liquid with a slightly sweet taste, although drinking it is harmful and can cause poisoning. It is a weak oxidizing agent and is used as an antiseptic and a bleaching agent. In diluted form, it is used to disinfect wounds and kill bacteria and viruses on the skin; in higher concentrations, it can be used to bleach hair or remove stains from clothing. It is also used as a propellant in rocketry and in certain industrial processes. Chemically, hydrogen peroxide is composed of two hydrogen atoms and two oxygen atoms, and it is structurally similar to water (H2O), with an extra oxygen atom. This gives it its oxidizing properties, as the additional oxygen can be released and used to react with other substances.
