Background: Individuals respond to statins differently due to genetic variations. One of the most significant enzymes involved in drug metabolism is CYP2D6 enzyme, coded by the CYP2D6 gene. Individuals who carry two non-functional alleles in this gene are considered as poor metabolizers (PMs). Recognizing poor metabolizers might help in preventing adverse effects of drugs. Objective: In this ...

coccinellids play a major role in aphid control. hippodamia variegata goeze is an aphidophagous predator of worldwide distribution that could be found in different parts of iran. one of the criteria for evaluating the efficiency of a predator is its response to change in prey population density (functional response). the functional responses of males and females of hippodamia variegata were stu...

introduction: few studies are conducted on the efficacy of antispasmodics in the treatment of functional gastrointestinal disorders in children. we evaluated the effectiveness of a smooth-muscle relaxant (mebeverine) in the treatment of childhood functional abdominal pain (fap).   materials and methods: children (n=115, aged 6-18 years) with fap were randomized to receive mebeverine 135 mg twic...

This paper investigates the global stability of virus dynamics model with BeddingtonDeAngelis infection rate. By constructing Lyapunov functions, the global properties have been analyzed. If the basic reproductive ratio of the virus is less than or equal to one, the uninfected steady state is globally asymptotically stable. If the basic reproductive ratio of the virus is more than one, the infe...

In this study, a system of delay differential equations arising from a three-species model with two predators feeding on a single prey is considered. It is assumed that the prey population grows logistically in the absence of predators, and both predator populations adapt a Holling type II functional response. Each response term includes a delay time, which reflects the gestation period of each...

Verifiable criteria are established for the permanence and existence of positive periodic solutions of a delayed discrete predator-prey model with monotonic functional response. It is shown that the conditions that ensure the permanence of this system are similar to those of its corresponding continuous system. And the investigations generalize some well-known results. In particular, a more acc...

Objectives. The Cognitive Performance Test (CPT) is a functional assessment for persons with dementia. The study purpose was to evaluate the reliability, discriminant, and concurrent validity of the CPT. Method. The CPT was tested against other measures of cognition (Standardized Mini Mental Status Exam (SMMSE) and Assessment of Motor and Process Skills-Process scale (AMPS-Process)). Participan...
