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...

aim and background: psychotic patients are at the risk of hyponatremia due to numerous reasons .given that severe hyponatremia can cause serious risks including seizures, coma and death, taking the symptoms into account seems necessary when patients referring to medical centers. therefore, the present study aimed to determine the prevalence rate of hyponatremia in psychotic patients in farshchi...

iodine is essential element in thyroid hormones synthesis and normal growth and development of the brain. milk and iodine concentrations can be appropriate indicator of body iodine status; in this study, we evaluated the concentrations of urine and milk iodine in newborns and their mothers.in a cross-sectional study conducted in 2013, urine and milk iodine in 106 neonates and their mothers refe...

background: the aim of this study was using elisa for detection of anti- schistosoma haemato­bium antibodies in both sera and urine of patients with urinary schistosomiasis. methods: thirty three sera and urine samples were collected from patients with acute schisto­somi­asis in diyala province, east of iraq in 2006.   their diseases were confirmed by find­ing   s. haematobium ova in urine exam...

background: the current study was conducted to compare elisa with thin layer chromatography (tlc) methods for diagnosis of morphine in the urine. methods: positive urine samples for morphine confirmed by immunochromatographic strips were collected from the imam reza toxicology laboratory, mashhad university of medical sciences, mashhad, iran in 2012 for the current study. then, the collated uri...

background: diagnosis of some diseases is difficult due to invasive sampling. urine has been candi-date as a non-invasive and convenient alternative. it has many advantages and easy accessibility but some technical ills should be removed. finding a suitable extraction method for improving urine dna quantity and quality in altering invasive specimens for molecular diagnosis of some infectious di...

In this paper, we have proposed an optical sensor design for urine analysis for diabetic applications. The sensor design consists of two dimensional photonic crystal ring resonator structure. Finite Difference Time Domain (FDTD) method has been used for the analysis. MEEP (MIT Electromagnetic Equation Propagation) simulation tool has been used for modeling and designing of photonic crystal ring...

background: cocaine poisoning is known for causing severe clinical effects such as tachycardia, hypertension, agitation and confusion. absence of clinical manifestations in cocaine poisoning is unusual. case report: a 26-year old man, known to be a cocaine addict, declared that he was forced by cocaine dealers to swallow many tablets of cocaine, six hours prior to admission to emergency departm...

BACKGROUND Previous researches pointed out that the measurement of urine fibronectin (Fn) could be a potential diagnostic test for bladder cancer (BCa). We conducted this meta-analysis to fully assess the diagnostic value of urine Fn for BCa detection. METHODS A systematic literature search in PubMed, ISI Web of Science, EMBASE, Cochrane library, and CBM was carried out to identify eligible s...
