the cytoplasmic male sterile (cms) lines that are used in production of hybrid seeds in three-line system often get contaminated with their maintainer lines. using such impure cms lines in rice hybrid seed production lead to un-uniformity and yield loss in hybrid rice. laborious and time consuming phenotypic evaluations are used for elimination of off-type plants in cms multiplication farms. th...

abstract background and objective: it has been shown that oxidative stress increases in diabetes and it has an important role in its development and subsequent complications. thus, the aim of this study was to investigate the effect of acute resistance exercise on oxidative stress in skeletal muscle and cardiac tissues of streptozotocin-induced diabetic rats. materials and methods: twenty male ...

Objective: The aim of present study was to investigate the difference of torque control during intrusion force in incisors with normal, under and over-torque in lingual and labial orthodontic systems through finite element analysis. Material and Methods: 3D models of an upper right central incisor with different torques were designed in Solid Works 2006.The models were transferred to the ANSYS ...

OBJECTIVE To find out if it is possible to control maxillary anterior teeth in sagittal and vertical plane during retraction by altering the vertical levels of force application in the posterior region, i.e. identifying the type of movement of the maxillary anterior teeth which occurs when force would be applied from four different levels i.e. High, Medium, and Low pull Implants and from a conv...

Background: This study aimed to compare the continuous rotation and reciprocating movements of rotary files in achieving apical patency root canal retreatment. Materials Methods: vitro, experimental evaluated 64 extracted mandibular molars. The teeth were prepared up F3 with ProTaper Universal obturated using lateral compaction technique. divided into four groups (n = 16) based on mesiobuccal c...
