A simple, economical, precise, accurate, and rapid HPLC method has been developed and validated for assay determination of ca and imidapril simultaneously in their raw material and tablet dosage forms. The chromatographic acetonitrile and phosphate buffer (25:75 v/v) ratio. The detection of Prills drugs was carried out at 210 nm with a flow rate retention(More)
Objective: The objective of the study: is the analysis of cinnamic acid (CA) from commercial herbal drugs, and from dried plant material used in traditional medicine in Jordan market qualitatively and quantitatively by using (HPLC) high performance liquid chromatography. Methods: The chromatographic conditions comprised of a reversed-phase RP-8 column with(More)
Spermatozoa generate reactive oxygen species (ROS) in physiological amounts, which play a role in sperm functions during sperm capacitation, acrosome reaction (AR), and oocyte fusion. In addition, damaged sperm are likely to be the source of ROS. The most important ROS produced by human sperm are hydrogen peroxide, superoxide anion and hydroxyl radicals.(More)
This study was conducted to evaluate the relation between cigarette smoking, semen quality and ratios of protamine mRNAs in smokers and non-smokers. Spermatozoa from 123 men and 64 smokers and 59 non-smokers whose female partners attended an assisted reproduction and andrology laboratory were evaluated. Protamine mRNA was extracted from purified sperm,(More)
While determining cefaclor in biological fluid, it could be degraded due to oxidation hydrolysis and racemisation. Furthermore, such degradation process can be accelerated depending on pH, temperature, carbon dioxide, oxygen, light, humidity and storage. Thus such measures are crucial in cefaclor determination in biological fluids and reducing or inhibiting(More)
Enalapril is an angiotensin-converting enzyme inhibitor used for treatment of hypertension and chronic heart disease. Enalaprilat is its active metabolite responsible for the activity. This study aimed to develop and validate a method for enalapril and enalaprilat analysis and to determine the bioequivalence of two tablet formulae of enalapril. LC-MS/MS(More)
Vitamin D is necessary for maintaining and regulating calcium levels; thus, insufficiency of vitamin D increases the risk of many chronic diseases. This study aimed to examine vitamin D levels among Jordanian and Iraqi volunteers and find the relation between vitamin D level and lipid profile patients. Vitamin D levels were evaluated using enzyme-linked(More)
