Magnetic twisting cytometry probes mechanical properties of an adherent cell by applying a torque to a magnetic bead that is tightly bound to the cell surface. Here we have used a three-dimensional finite element model of cell deformation to compute the relationships between the applied torque and resulting bead rotation and lateral bead translation. From the analysis, we computed two coefficie...
طی ده سال گذشته، خون بندناف به عنوان یک منبع جایگزین برای بدست آوردن سلولهای خونساز، در پیوند آلوژنیک مورد توجه قرار گرفته است .از مزایای خون بند ناف سهل الوصول بودن آن بوده و همچنین کم بودن سلولهای t در این نمونه می باشد . از طرفی اکثر سلولهای t موجود نیز مبتدی می باشند. همین ویژگی باعث می شود تا در استفاده از این سلولها برای پیوند مغز استخوان کمتر شاهد بروز بیماری پیوند علیه میزبان در گیرندگا...
background: although the imbalance of cytokines in head and neck squamous cell carcinoma (hnscc) is well known, there is scarce data regarding its occurrence during dysplasia, before the malignant transformation. objective: to determine whether laryngeal dysplasia patients show a different cytokine profile than patients with cancer and healthy controls. methods: seventeen newly diagnosed, untre...
The non-continuous laser beam in pulsed lasers allows the mechanical peening between two consecutive beams on a still hot weld bead. At a very short time (20, 150 and 300 ms) after laser pulse application, mechanical peening was performed on the welding bead. To achieve these short times, the light sensor detects the nth laser pulse and the mechanical arm starts moving. Upon reaching the tip of...
Background: Although DC Bead has been useful in treatment of multiple and large hepatocellular carcinoma, loading time of doxorubicin into the DC Bead takes a long time of 30-120 minutes. Epirubicin is also used as an antitumor agent together with DC Bead, but its loading efficiency was not sufficiently elucidated. Methods: To shorten loading time of epirubicin into DC Bead (100-300μm, 300-500μ...

Characterization of flaws of weld bead is imperative for high-quality welding. Methods of weld bead inspection include radiographic, ultrasonic and vision inspection. However, such methods are costly and time consuming. The proposed sensor is light, low-cost and fast. This paper summarizes our work on weld bead monitoring and defect detection using an electromagnetic sensor. Measurements are ac...
Austenitic stainless steel SS304 grade was welded with active Tungsten Inert Gas (TIG) welding process by applying a flux paste made of SiO2 powder and acetone. SiO2 flux application improves the weld bead depth with a simultaneous reduction in weld bead width. The improvement in penetration results from arc constriction and reversal of Marangoni convection. Experimental studies revealed that t...
