phytoremediation is an eco-friendly method for removal of pollutants, which can be relied upon as a sustainable technology, if implemented under optimum conditions of plant growth. the effectiveness of water hyacinth, a topical weed, for the removal of zinc (zn) and chromium (cr) ions from aqueous solutions has been presented in this article. the potential of this plant in removing metals by ph...
FtsK translocates dsDNA directionally at >5 kb/s, even under strong forces. In vivo, the action of FtsK at the bacterial division septum is required to complete the final stages of chromosome unlinking and segregation. Despite the availability of translocase structures, the mechanism by which ATP hydrolysis is coupled to DNA translocation is not understood. Here, we use covalently linked transl...
down’s syndrome, or 21 trisomy, is the most common autosomal abnormality, with incidence of 1 per 815 live births in iran. worldwide reports indicate that about 95% are regular trisomy, or nondisjunction, 1% are mosaic and 4% due to translocation. however, these values show a geographical variation. a cytogenetic study of down's syndrome, or trismoy 21, was carried out on 366 cases (202 males a...
Serpentine soils are dry and contain rather high levels of nickel (Ni).To obtain a better understanding of drought tolerance by Ni in serpentine plants, a hydroponic trial was designed to compare the effects of Ni on growth factors, Ni uptake or translocation and some physiological parameters in the serpentine plant, Fortuynia garcinii (Burm.f.), under PEG simulated drought stress (3 levels). A...
Introduction: One of the serious complications of intra uterine device (IUD) is uterine perforation and translocation of it to abdominal organs. Translocation is usually accompanied with abdominal or pelvic pain and absence of string in vaginal examination. Therefore, it was decided to report an asymptomatic case of translocation of IUD to small bowel serosa with presence of string in vaginal e...
The remarkable ability of our vision to function under ever-changing conditions of ambient illumination is mediated by multiple molecular mechanisms regulating the light sensitivity of rods and cones. One such mechanism involves massive translocation of signaling proteins, including the G-protein transducin, into and out of the light-sensitive photoreceptor outer segment compartment. Transducin...
critical thinking ability has an important role in education. accordingly, scholars around the world are searching for new ways for teaching and improving students critical thinking ability. in line with the studies in efl contexts supporting the positive relationship between critical thinking and writing performances, this study investigated the differential effects of halverson’s critical thi...
