BACKGROUND Exposure to environmental chemicals, including phthalates and phenols such as parabens and triclosan, is ubiquitous within the U.S. general population. OBJECTIVE This proof-of-concept rodent study examined the relationship between oral doses of three widely used personal care product ingredients [diethyl phthalate (DEP), methyl paraben (MPB), and triclosan] and urine and serum conc...
A simple and precise stability-indicating liquid chromatography method is developed and validated for the quantitative simultaneous estimation of irbesartan (IRB) and hydrochlorothiazide (HCTZ) in combined pharmaceutical dosage form. A chromatographic separation of the two drugs was achieved with an Ace5 C(18) 25-cm analytical column using buffer-acetonitrile (70:30 v/v). The buffer used in mob...
ing (eg, a rug) rather than on a slippery surface or table. Care should be taken to intimidate the dog as little as possible; lifting the dog to an examination table, giving injections, etc, should be performed after the semen is collected. Semen may be collected in the absence of a bitch (although sperm numbers may be lower), but the presence of a bitch is preferable. The pheromone methyl para...
Xanthelasma is the most common type of xanthoma in periorbital region with clinical diagnosis. About 50% patients have hypercholesterolemia laboratory tests - inferring importance to this condition. We aim report a case 55-year-old female patient presenting yellowish papules on upper eyelids diagnosed as Xanthelasma. She had and II diabetes use rosuvastatin 10mg metformin 1000mg. complaint sign...
BACKGROUND Parabens are preservatives commonly used in personal care products, pharmaceuticals, and foods. There is documented widespread human exposure to parabens, and some experimental data suggest that they act as estrogenic endocrine disruptors. As far as we are aware, no epidemiologic studies have assessed female reproductive health effects in relation to paraben exposure. OBJECTIVE We ...
BACKGROUND Exposure to certain phenols is ubiquitous because of their use in many consumer and personal care products. However, predictors of exposure have not been well characterized in most populations. OBJECTIVES We sought to identify predictors of exposure and to assess the reproducibility of phenol concentrations across serial spot urine samples among Chinese adults. METHODS We measure...
A stability-indicating RP-HPLC method has been developed and validated for the simultaneous determination of methylparaben (MP), propylparaben (PP), diethylamino hydroxybenzoyl hexyl benzoate (DAHHB), and octinoxate (OCT) in topical pharmaceutical formulation. The desired chromatographic separation was achieved on the Kinetex(TM) C18 (250 × 4.6 mm, 5 μm) column using gradient elution at 257 nm ...
This article explains the developed and validated rapid, timesaving, cost-effective UHPLC method for simultaneous quantification of cinnarizine, its five specified impurities (Impurity-A to E), two degradation products (cinnamyl piperazine benzhydrol), antioxidants (methylparaben propylparaben). Furthermore, when coupled with a mass spectrometer, proposed provides additional advantages confirma...
Topical drug delivery system improved bioavailability, reduced side effects, more uniform plasma levels, longer duration of action, resulting in a reduction dosing frequency and improve therapy due to levels up the end interval compared decline with conventional oral dosage form. Emulgel are generally used where other systems administration fails directly treat cutaneous disorders such as funga...
