پایان نامه حاضر در مورد امکان سنجی استفاده از مدلسازی آماری مبـتنی برbmd جهت برآورد حجم بحرانی خونریزی درایجاد مقادیر معینی از خطر مرگ ناشی از خونــریزی مــغزی غیرتروماتیک(خود به خودی) می باشد. روشbmd در رابطه با مقدار دوز یا حجم بحرانی یک وضعیت از پیش تعیین شده برای بدست آوردن بهترین پاسخ جهت ارزیابی خطرات سلامتی و بهداشتی و همچنین برآورد مقدار یا حجم بحرانی دوز می باشد. روشbmd یک روش جایگزین...
This clinical report describes the prosthetic management of a patient following total glossectomy and total laryngectomy that severely compromised his oral function, caused facial disfigurement, and limited the patient's quality of life. A feeding aid prosthesis was designed to address the patient's chief complaint of difficulty in feeding and mastication. The prosthesis was designed as an impl...
اسانس گیاه شوید در درمان هیپرلیپیدمی در یک دوره مزمن به بیماران تجویز می شود. در این مطالعه سمیت احتمالی تحت مزمن اسانس این گیاه مورد بررسی قرار گرفت، حال آنکه در مصرف حاد این اسانس سمیتی گزارش نشده است. در این آزمایش 40 رت ماده به 4 گروه 10 تایی تحت گروههای شاهد، a(high dose)، (intermeidate dose)b و (low dose)c تقسیم شد و اسانس بصورت خوراکی تحت دوزهای به ترتیب بالا: بدون اسانس، 2 م...
PURPOSE To conduct phase 1 and 2 trials with photon intensity modulated radiation therapy and intensity modulated proton therapy (IMPT) arms to selectively escalate the retroperitoneal sarcoma preoperative radiation dose to tumor volume (clinical target volume [CTV] 2) that is judged to be at a high risk for positive margins and aim to reduce local recurrence. We report on the IMPT study arm in...
Previously, we have shown that gaseous Nitric oxide (gNO) has great potential as an effective topical anti-infective agent for non-healing wounds due to its non-specific antimicrobial properties. These same antimicrobial attributes may be useful for pulmonary infections. However, gNO would have limited usefulness as an inhaled antimicrobial agent as continuous exposure to the concentration requ...
background: annual patient effective dose equivalent can be considered as a quantitative physical parameter describing the activities performed in each nuclear medicine department. annual staff dose equivalent could be also considered as a parameter describing the amount of radiation risk for performing the activities. we calculated the staff to patient dose equivalent ratio to be used as a phy...
In an attempt to determine appropriate diet in nephrotic syndrome, nephrotic rats, induced by puromycin aminonucleoside, were nourished by total parenteral nutrition fluid containing the same energy, but three different levels (1.65, 3.3, and 6.6%) of amino acids for 7 d. The fractional rate of total protein synthesis in the liver was determined by injecting a flooding dose of [3H]phenylalanine...
background: the shielding methods in radiotherapy due to delivering an accurate radiation dose to cancer tissues and avoiding unnecessary dose to normal tissues are very important. these methods include lead standard blocks, individual molding and multi leaf collimator (mlc). the mlc method is not still common in iran radiotherapy centers. individual molding is better than the lead block shield...
Total knee arthroplasty (TKA) for osteoarthritis (OA) patients with extra-articular deformity is still challenging because angular deformity, canal sclerosis, or the retained hardware that precludes the use of the traditional intramedullary guide. In addition, atypical bone cut for intra-articular correction leads to imbalanced soft tissue gap. Furthermore, corrective osteotomy should be consid...
