BACKGROUND The presence or absence of metastatic disease in cervical lymph nodes is the single most important determinant of therapy and prognosis for patients with head and neck squamous cell carcinoma (HNSCC). However, histologic examination fails to detect metastatic disease in a subset of neck dissection specimens. The accuracy of neck staging may be improved by the use of molecular techniq...
OBJECTIVES/HYPOTHESIS To report tolerance and toxicity of radiotherapy (RT) with or without chemotherapy in HIV seropositive patients with squamous cell carcinoma of the head and neck (SCCHN). METHODS This is a single institution retrospective study of 73 HIV seropositive patients with SCCHN treated from January 1997 through 2010. Stages I, II, III, and IV were 8%, 10%, 24%, and 58%, respecti...
Horizontal directional drilling is usually used in drilling engineering. In a variety of conditions, it is necessary to predict the torque required for performing the drilling operation. Nevertheless, there is presently not a convenient method available to accomplish this task. In order to overcome this difficulty, the current work aims at predicting the required rotational torque (RT) to opera...

Background: Advanced cancers frequently metastasize to bone, and the presence of bone metastases is the most common cause of cancer-related pain. Pain management requires a multidisciplinary approach that involves the use of analgesics, bisphosphonates, radiotherapy, chemotherapy, surgery. The aim of our study was to evaluate the enhancement of radiotherapy on painful bone metastases in patient...
Abstract Aim Traumatic Cardiac Arrest (TCA) is a potentially fatal consequence of penetrating or blunt trauma. Emergency-Department Resuscitative Thoracotomy (ED-RT) the last resort procedure to restore cardiac output following TCA. This study reviews current UK guidelines Major Trauma Centres (MTCs) identify common indications for ED-RT and chest compressions Method Departmental policies were ...
Under a suitable sparsity condition on the exponents Λ = {λk = τk+ iσk}, it is shown that the individual terms cT = {ck ek} can be obtained from observation of the L function f(t) = ∑ ck e iλkt through the ‘window’ t ∈ [0, δ] — with an ` estimate (uniform for such Λ) asymptotically as T, δ → 0. Some applications are given to control theory for partial differential equations.
Let Ea : y 2 + xy = x + ax + 1/F2m be a Koblitz curve. The window τ -adic nonadjacent-form (window τNAF) is currently the standard representation system to perform scalar multiplications on Ea by utilizing the Frobenius map τ . Pre-computation is an important part for the window τNAF. In this paper, we first introduce μτ̄ -operations in lambda coordinates (μ = (−1)1−a and τ̄ is the complex conjug...
زمینه مطالعه: بیماری نیوکاسل یکی از مخرب ترین بیماریهای ویروسی طیور در سرتاسر جهان است. هدف: با توجه به اینکه روشهای سنتی قابلیت محدودی در کنترل این بیماری دارند، انجام این مطالعه به منظور استفاده از تکنولوژیهای نوین برای تشخیص به موقع بیماری جهت کاهش خسارت پیش روی صنعت طیور میباشد. روش کار: استخراج RNA با استفاده از کیت RNease mini و بر اساس دستورالعمل شرکت سازنده انجام شد. RNA استخراج شده ...
Objectives We reviewed testosterone changes for patients who were treated with radiation therapy (RT) alone on NRG oncology RTOG 9408. Methods and materials Patients (T1b-T2b, prostate-specific antigen <20 ng/mL) were randomized between RT alone and RT plus 4 months of androgen ablation. Serum testosterone (ST) levels were investigated at enrollment, RT completion, and the first follow-up 3 m...
