INTRODUCTION We developed a new fast imaging technique with flexible time-resolved angiography with stochastic trajectories (TWIST) view sharing to achieve variable temporal resolution and with flexible echo time Dixon to achieve robust fat suppression and to evaluate its application in breast dynamic contrast enhanced-magnetic resonance imaging (DCE-MRI). MATERIALS AND METHODS The TWIST-Dixo...
The Rotterdam mandibular distractor (RMD) is a slim, rigid, boneborne distractor for use in midline distraction of the mandible. We did a biomechanical study to compare the RMD with the Trans Mandibular Distractor-flex (TMD-flex). This included an anatomical biomechanical study that was conducted on 9 dentate human cadaveric heads using both the RMD and the TMD-flex. In the vertical plane less ...
Background: Stainless steel instruments have long used as conventional instruments applied in root canal therapy procedures. Being difficult the canal preparation by these instruments, a new generation of nickel-titanium instruments have introduced. The aim of this study was to compare the manual Ni-Ti instruments with the Flex Master® Ni-Ti rotary system in canal preparation. Materials & M...
محدوده کفاز سفلی با وسعت 58 کیلومترمربع در جنوب شرقی استان خراسان جنوبی واقع شده است. پردازشهای آماری تک متغیره و چند متغیره بر روی دادههای آنالیز رسوبات آبراههای، نشان داد که توزیع مس به عنوان یک عنصر غنی شده در منطقه به صورت دو جامعهای بوده و بیشترین همبستگی را با عناصر کروم، کبالت، نیکل، تیتانیوم و منیزیم دارد. با توجه به اینکه کانیسازی خفیف مس (به صورت مالاکیت و آزوریت) با ریخت رگچهای...
Ceramic capacitors have proven themselves very reliable with extremely low failure rates. As processes continue to improve, reliability of the dielectric also continues to increase. This increase in the reliability of the dielectric has caused other categories to emerge as the main contributors to the overall failure rate. A recent review of field failure analysis of surface mount MLCCs, has sh...
PURPOSE To evaluate the impact of a change in the manufacturing of the AneuRx stent-graft on the long-term results of endovascular abdominal aortic aneurysm (AAA) repair. METHODS The first 70 AAA patients treated with the AneuRx stent-graft between October 1996 and December 1998 were reviewed. The early stiff bifurcated design (STIFF) was used in 23 patients (mean age 71.7 +/- 9.3 years, rang...
OBJECTIVE The requirement to inject current basal insulin analogs at a fixed time each day may complicate adherence and compromise glycemic control. This trial evaluated the efficacy and safety of varying the daily injection time of insulin degludec (IDeg), an ultra-long-acting basal insulin. RESEARCH DESIGN AND METHODS This 26-week, open-label, treat-to-target trial enrolled adults (≥18 year...
Today for a security critical and safety application in automotives, a protocol is required which can transfer the data with a higher speed than existing protocol. As concepts like x-by-wire(x used for drive, steer, brake, etc.,)where steering arms and brake pipes are replaced by electric wire and integrated circuits, a robust and fail-safe communication is needed, and Flex Ray is fulfilling th...
پروتئینازk (3.4.21.14ec ) یک اندوپپتیداز خارج سلولی است که به وسیله قارچ tritirachum album limber ترشح می شود و متعلق به رده سرین اندوپپتیداز هاست. این آنزیم دارای 279 اسید آمینه است. در جایگاه فعال این آنزیم سه اسید آمینه 39asp ، 69his و224 ser وجود دارد. پروتئیناز k تک زنجیره ای با وزن مولکولی 9/28 کیلو دالتون می باشد. این آنزیم در ph 3 تا 11 بسیار پایدار و فعال است. نقطه ایزوالکتریک این آنزی...
