The influence of the intestinal microbial reduction of rhein anthraquinone on the formation of deterioration products was studied. Therefore [14C]rhein and [14C]rhein anthrone were mixed with sterilized or non-sterilized cecal mass of rats and incubated for 20 hours at 37 degrees C. Extractions with
Musty "off-flavor" in pond-cultured channel catfish (Ictalurus punctatus) costs the catfish production industry in the United States at least 30 million US dollars annually. The cyanobacterium Oscillatoria perornata (Skuja) is credited with being the major cause of musty off-flavor in farm-raised
In an attempt to study the relative toxicity of anthraquinonic laxatives on intestinal mucosa, we compared in mice the effects of fruit pulp containing sennosides A and B with those of a free anthraquinone, 1-8 dihydroxyanthraquinone. Observations have been made with transmission electron microscopy
Parkinson's disease (PD) results from the degeneration of the nervous tissue brought about by ecological and hereditary components which affects nerve cells in the brain. It is the world's second most normal neurodegenerative issue, which can essentially weaken the personal satisfaction, make
Anthraquinone dyes are utilized by the military in colored-smoke grenades. During production, workers in munitions plants may be exposed to fugitive emissions of these dyes or mixtures thereof. The effects of a prototype violet dye mixture (VDM) consisting of Disperse Red 11 (DR11),
Chinese herbal medicine preparations are widely available and often regarded by the public as natural and safe remedies for a variety of medical conditions. Nephropathy caused by Chinese herbs has previously been reported, usually involving the use of aristolochic acids. We report a 23-year-old
OBJECTIVE
To compare the bidirectional effect of rhubarb total anthraquinone (TA) and total tannins (TT) on rats' liver.
METHODS
One hundred rats were randomly divided into 10 groups, i.e., the blank group, the model group, the blank + high dose TA group, the blank +low dose TA group, the blank +
Rhubarb is commonly used to treat constipation in China and anthraquinones (AQs) are the active components present in rhubarb. However, an increasing number of studies have reported that AQs induce nephrotoxicity. In the present study, rhubarb total free anthraquinones (RTFA) oral colon-specific
Intervertebral disc degeneration (IDD) is regarded as an important cause of low back pain, which continues to be a common disability. IDD is thought to involve sequential changes of intervertebral disc that lead to the reduction of disc cells and the extracellular matrix. In addition, inflammation
Pharmacologic treatment of osteoarthritis has been confined mostly to analgesic or nonsteroidal antiinflammatory drugs that only modify the symptoms. We asked whether anthraquinone-2,6-disulfonic acid might act as a disease-modifying osteoarthritis drug. We evaluated the in vitro inhibitory effect
OBJECTIVE
To isolate polyketide synthase (PKS) gene from medicinal Usnea longissima lichen forming fungi, and identify the function of obtained PKS.
METHODS
We used Usnea. longissima lichen forming fungi to isolate PKS gene by nested PCR using degenerate primers and screening a Fosimid genomic
A single non-toxic dose of mitoxantrone or a related anthraquinone derivative caused extensive destruction of splenic marginal zone cells in rats and mice. This was followed by phagocytosis of cell debris and long-lasting atrophy. Germinal centers of splenic follicles were also affected. Small doses
2-(dideuteriomethylene)-1,1-bis(4-methoxyphenyl)cyclopropane (d(2)-1) undergoes degenerate rearrangement in both singlet- and triplet-sensitized electron-transfer photoreactions. Nanosecond time-resolved absorption spectroscopy on laser flash photolysis of the unlabeled 1 with
For years, the aprotic Li-O2 battery suffered from a severe capacity-current trade-off that would be unacceptable for a beyond Li-ion battery. Recent fundamental study of Li-O2 electrochemistry revealed that this dilemma is caused by the growth of Li2O2 on the cathode surface and can be solved by
We characterize the transcript of a polyketide synthase gene (PKS) from the cultured mycobiont of Xanthoria elegans (XePKS1) using SMART-rapid amplification of cDNA ends (RACE) cDNA synthesis. Sequence analysis of the cloned cDNA reveals an open reading frame of 2144 amino acid residues. It contains
