BACKGROUND AND PURPOSE Future aneurysmal behaviors or treatment outcomes of cerebral aneurysms may be related to the hemodynamics around the inflow zone. Here we investigated the influence of parent artery curvature on the inflow zone location of unruptured sidewall internal carotid artery aneurysms. MATERIALS AND METHODS In 32 aneurysms, the inflow zone location was decided by 4D flow MR ima...

objective- to evaluate the application of carbomer 940 hydrogel on saving zone of stasis in skin burn wound. design- experimental study animals- twenty rats. procedures- after shaving the backs, a ‘comb burn’ was contacted bilaterally on the dorsum of the rats 0.5 cm lateral and parallel to the midline by using a brass probe consisting of four rows (10×20 mm) and three interspaces (5×20 mm). al...

The seventh international seminar on Vygotsky held in Geneva discussed a new French language translation of texts from ‘pedology,’ the now largely lost Soviet science developing child. In this introduction, guest editors touch three concepts development which coincide with elements Vygotsky’s best known idea, Zoped, or zone proximal development. each case, we find that pedological has potential...

One of the locations of renal artery atherosclerosis is at the orifice of the renal artery, therefore thestructure of this orifice was assessed in 6 normal, adult male dogs by light microscopy (LM) andtransmission electron microscopy (TEM). For the LM study, processed tissues were embedded in paraffinand sectioned serially into 6-μm thickness. Sections were stained with orcein. For the TEM stud...

background and aims. with the introduction of cone beam computed tomography (cbct) in dentistry, a question has been raised whether the technique significantly increases the diagnostic accuracy in comparison with other techniques or not. therefore, the present study was undertaken to assess the accuracy of cbct modality in detecting proximal carious lesions as compared to conventional periapica...

background: colorectal cancer (crc) is the second cause of cancer-related deaths worldwide. there have been several studies reporting the proximal tumor shift, especially in western countries. in the present study, we investigated the clinicopathologic and anatomical distributions of colorectal tumors in iranian crc patients. materials and methods: in this retrospective cohort study,258 patient...
