Contraceptive patches have become a frequently used contraceptive method. We present a mathematical model that describes the serum concentration profiles of Norelgestromin (NGMN) and Ethinylestradiol (EE) released from the contraceptive patch Ortho Evra®. We propose a simple one-compartment model based on pharmacokinetics data reported in previous studies. The model assumes a time-dependent rel...

Budding is a good method of propagation in the Persian walnut (Juglans regia L.)., However, success of budding is low due to higher root pressure as well as the presence of phenolic compounds in the xylem sap. This study was conducted to compare various budding methods and cut below budding union on two and three-year-old Persian walnut under field conditions. The experiment was conducted based...

a-10-year-old girl was referred to our department for multiple hyperpigmented plaques. one  week  previously,  she  had  been  given  one  suppository  of  acetylsalicylic acid  – phenobarbital for fever. twelve hours after the drug intake the child developed pruritic red plaques on the left thigh. six weeks after resolution of the acute reaction, patch tests were performed separately, with phe...
