The 24-hr urine sodium excretion level was estimated based on the spot urine sodium, and the efficacy of the formula was validated to determine the status of low salt intake <100 mEq Na/day. The 24-hr urine samples were collected from 400 patients. The 24-hr urine creatinine level was estimated with the use of three formulas: a newly derived Korean equation (E24UCR_K), and Tanaka (E24UCR_T) and...

novel dispersive liquid-liquid microextraction (dllme), coupled with high performance liquid chromatography with photodiode array detection (hplc-dad) has been applied for the extraction and determination of cyproheptadine (cph), an antihistamine, in human urine samples. in this method, 0.6 ml of acetonitrile (disperser solvent) containing 30 µl of carbon tetrachloride (extraction solvent) was ...

objective: the current methods for bladder cancer diagnosis suffer from low sensitivity and specificity. therefore, finding a novel tumor markers with high specificity and sensitivity is of great interest. micrornas (mirna, mir) are small endogenously-produced, non-coding rnas with an important role in regulating gene expression. recent studies show that mirnas expression profiles represent sig...
