conclusion according to the results of our series, percutaneous liver biopsy using the tru-cut biopsy gun guided by ultrasonography can be performed safely. we resolve that routine ultrasound of the puncture site is a quick, effective and safe procedure. the complication rate is very low. the us-assisted percutaneous liver biopsy should be used for all cases. results a total of 1018 patients we...
Abstract It is foreseeable that the BeiDou navigation satellite system with global coverage (BDS-3) and (regional) (BDS-2) will coexist in next decade. Care should be taken to minimize adverse impact of receiver-related biases, including inter-system biases (ISBs), differential code (DCB), phase (DPB) on positioning, navigation, timing (PNT) provided by systems (GNSS). Therefore, it important a...
در این نوشتار مساله محاسبه ضریب شدت تنش برای یک ترک ساکن با در نظر گرفتن اثر تغییر شکل برشی در یک نمونه dcb مورد بررسی قرار گرفته است بدین منظور نمونه متشکل از دو تیر تیموشنکو در نظر گرفته می شود که در ناحیه تماسشان تکیه گاه الاستیک winkler قرار دارد. مسئله در حالت کلی مورد تحلیل قرار می گیرد. ولی در حالت خاصی که طول ناحیه پس از نوک ترک در مقیاس ارتفاع نمونه باشد. رابطه ساده و مختصری ارائه می گ...
The role of the caspases, a newly discovered group of cysteine proteases, was investigated in a model of hypoxia-induced necrotic injury of rat renal proximal tubules. An assay for caspases in freshly isolated rat proximal tubules was developed. There was a 40% increase in tubular caspase activity after 15 min of hypoxia in association with increased cell membrane damage as indicated by a three...
The aim of this study is to evaluate the effect processing temperature on interfacial failure glass/Elium® 150 composites. vacuum assisted resin transfer molding technique (VARTM) was used manufacture composites at three different process temperatures: room (24℃), 50℃ and 80℃. interlaminar shear strength, mode I II fracture toughness laminates were determined by performing short beam (SBS), dou...
Abstract The {0001} basal plane delamination dominating the crack-wake bridging in MAX phases at a bulk scale has been investigated by studying small-scale fracture of Ti 3 SiC 2 . In situ micro-double cantilever beam (DCB) tests scanning electron microscope were used to grow stable crack along plane, measure energy, and study propagation mechanism nanoscale. results show that energy (10–50 J/m...
background : lung cancer is still the leading cause of cancer- related deaths and most of themâ are normally diagnosed in late stages, so there is an urgent need to establish reliable tools for the identification at early stages of the disease. in this study, we use an eleven gene signature test to examine lung biopsy specimens for diagnostic, prognostic & therapeutic purposes. methods : bronc...
BACKGROUND Inhibition of programmed death-ligand 1 (PD-L1) with atezolizumab can induce durable clinical benefit (DCB) in patients with metastatic urothelial cancers, including complete remissions in patients with chemotherapy refractory disease. Although mutation load and PD-L1 immune cell (IC) staining have been associated with response, they lack sufficient sensitivity and specificity for cl...
