آگاهی از سطح تنوع ژنتیکی و برآورد آن در ژرم پلاسم های گیاهی اساس بسیاری از برنامه های اصلاحی به شمار می رود. نشانگرهای ssr به دلیل تکرارپذیری بالا، ماهیت چندآللی، امتیازدهی هم بارز و فراوانی ژنومی بالا، کاربرد فراوانی در بررسی تنوع ژنتیکی و روابط بین ژنوتیپ ها دارند. یکی از مشکلات کار با نشانگرهای ریزماهواره، طراحی آغازگرهای اختصاصی بر مبنای نواحی جناحین این جایگاه ها است که زمان بر و پرهزینه ا...
rested on sociocultural theory (sct), this study attempted to examine the effect of written corrective feedback (wcf) followed by producing written languaging on developing writing accuracy over new tasks. to this aim, two intact iranian efl classes at the low-intermediate level were randomly assigned to two experimental groups: direct (n = 25) and indirect (n = 25). both groups wrote on a numb...

Changes in the sensitivity of hepatocytes to initiation during the cell cycle were investigated in partially resected hydroxyurea-synchronized regenerating rat liver. At defined periods of the cell cycle the animals were given injections of a single dose of N-methyl-N-nitrosourea (MNU) (25 mg/kg) and were subsequently exposed to diethylnitrosamine for 30 days (2 mg/kg/day) or to phenobarbital (...
this study was an attempt to investigate the effect of teaching meta cognitive strategies on iranian intermediate efl students speaking proficiency. in this study the researcher has employed metacognitive strategies taken from brown (2000) to teach speaking strategies to number of participants. the participants were intermediate students of shokouh language institute; they were divided into an ...
let h be a separable hilbert space and let b be the set of bessel sequences in h. by using several interesting results in operator theory we study some topological properties of frames and riesz bases by constructing a banach space structure on b. the convergence of a sequence of elements in b is de_ned and we determine whether important properties of the sequence is preserved under the con...
there are two major theories of measurement in psychometrics: classical test theory (ctt) and item-response theory (irt). despite its widespread and long use, ctt has a number of shortcomings, which make it problematic to be used for practical and theoretical purposes. irt tries to solve these shortcomings, and provide better and more dependable answers. one of the applications of irt is the as...
Although non-muscle invasive bladder cancer (NMIBC) is widely seen in men, most laboratory studies of new intravesical therapies to prevent NMIBC have been conducted on female animals. In addition, ozone (O3) has been shown to be a beneficial agent as an intravesical application in the treatment of various disorders. In the current study, we evaluated the immunohistopathological and oxidative-a...
The Annona muricata (Family-Annonaceae) fruit contain annonaceous acetogenins which have an effect on cancer cell as reported in many research studies. This study was aimed to evaluate the of methanolic extract (MFEAM) breast histology and invasive MNU-induced mice. Fifty female albino mice were divided into five groups (of ten each): control; cancer; + 200 mg/kg, 300 mg/kg 500 mg/kg. indicates...
Incorporation and alkaline sucrose sedimentation studies of DNA from mouse L-cells have demonstrated the following effects of N-methyI-N-nitrosourea (MNU) and methyl methanesulfonate (MMS). Increasing the concentration of both agents increases the number of single-strand breaks or alkali-labile lesions of existing DNA, which affects the incorporation of [~H]thymidine into DNA by reducing its re...
