Seed development: With or without sex?
In Arabidopsis, mutations in the genes FIE, FIS2 or MEDEA disrupt the normal dependence of seed development on fertilization. The products of these genes are similar to Polycomb group proteins, suggesting possible mechanisms for determining whether seeds can be produced sexually or asexually.
متن کاملThe Effect of Grape Seed Oil Enema with or without Sesame Oil in Acetic Acid Induced Ulcerative Colitis of Rats
BACKGROUND Inflammatory bowel diseases contain two digestive system diseases, ulcerative colitis (UC) and Crohn’s disease with unclear causes. The aim of present study was to investigate the therapeutic effects of administration of the Sesame oil (SO) and grape seed oil (GSO) as enema route in rats suffering from experimental acetic acid induced UC. METHODS Eighty male rats were ...
متن کاملSynthesis of Silica-coated Iron Oxide Nanoparticles: Preventing Aggregation Without Using Additives or Seed Pretreatment
The Stober process is frequently used to prepare silica-coated iron oxide nanoparticles. This is usually achieved by seeding a reaction mixture consisting of water, ethanol and a catalyst with iron oxide particles and adding a silica precursor. The hydrolysis and condensation of precursor monomers results in the deposition of a silica layer on iron oxide particles. However, this process is acco...

متن کاملAnterior Cruciate Ligament Reconstruction with or without Bracing
Background: Rupture of anterior cruciate ligament (ACL) would cause instability and disability and if left untreated. Reconstruction is performed by different techniques including patellar bone graft, as the strongest device. Application of brace after ACL reconstructions has revealed doubtful results. Methods: One hundred ACL ruptured patients randomized into two groups were reconstructed with...
