introduction: previous studies have shown that vitamin a and its derivatives such as retinoid and all-trans retinoic acid have a crucial role in memory, learning and synaptic plasticity. the receptors of vitamin a are seen in different parts of the brain such as hippocampus, where vitamin a has an important role in learning. in this study, the effect of intrahippocampal (ca1) injection of all –...

From Sep. 1984 to Aug. 1990,99 patients were treated for ureteral stone using the urekroscope. In five patients ureteroscopy was repeated for a second stone. In one patient the procedure was diagnostic in nature and in the rest of the patients it had a curative value. In 60 patients the stone was removed by electrohydraulic and basket combination and in25 cases, dilatation alone was enough...

Objective(s): Trans-chalcone as the parent member of the chalcone series reduces circulating levels of insulin and glucose. However, the cellular mechanism of these effects is poorly understood. Sirtuin 1 (SIRT1) as a direct target of miR-34a controls homeostasis of glucose, and also improves insulin sensitivity. Therefore, the present study for the first time investigated the influence of tran...

  Background: Trans-scaphoid perilunate fracture-dislocation and perilunate dislocations are among uncommon injuries, most commonly seen in young patients due to high energy trauma. The treatment can be achieved either surgically by open reduc tion and internal fixation or closed reduction and casting.   Methods: To compare surgical versus non-operative results of treatment of trans-scaphoid pe...

The preparation of trans-dihydrofurans has been achieved by a one-pot condensation reaction of 4-bromophenacyl bromide, aromatic aldehydes and 5,5-dimethyl-1,3-cyclohexanedione using biosynthesized CuO nanoparticles under reflux conditions in ethanol. CuO nanoparticles (CuO NPs) were prepared using extractof leaves of Ajuga chamaecistus Subsp. Scoparia. The key advant...
