The early diagnosis of biomarker is crucial for patient survival and successful prognosis of the disease, and for this reason sensitive and specific methods are required for early cancer diagnosis. However, common techniques for separation and concentrating biomarker are not optimal from the viewpoints of sensitivity and selectivity because analyzing these biomarkers from a small amount of serum is difficult due to the complexity of the sample and low levels of these biomarkers. Peptide imprinted polymers were developed for detection of progastrin releasing peptide (ProGRP); a low abundant...

A mathematical model that expresses total trihalomethane (TTHM) concentration in terms of initial chlorine concentration, total organic carbon, bromide ion concentration, contact time, and pH is developed for Zai water treatment plant which supplies water to Jabal Amman. Laboratory studies of THMs formation upon chlorination and bromide ion addition at different points of Zai treatment plant were performed.Results showed an increase in THMs concentration upon increasing contact time and chlorine dose. TTHM in the effluent water from Zai treatment plant ranged from 22 ppb to 63 ppb; these...
