13. An Extended Linear Discontinuous Method for One-group Fixed Source Discrete Ordinates Problems with Isotropic Scattering in Slab Geometry
RESUMO Atualmente, a obtenção de uma solução numérica precisa para problemas de fonte fixa em ordenadas discretas é relevante em muitas áreas da engenharia e das ciências. Neste trabalho, estendemos o método híbrido Elementos Finitos-Espectro Nodal (FEM-SGF), que foi originalmente desenvolvido para resolver problemas de autovalores de difusão, par

14. Robot assisted radical prostatectomy in kidney transplant recipients: surgical, oncological and functional outcomes of two different robotic approaches
ABSTRACT Background: To date, few series on robot-assisted radical prostatectomy (RARP) in kidney transplant recipients (KTRs) have been published. Purpose: To report the experience of two referral centers adopting two different RARP approaches in KTRs. Surgical, oncological and functional results were primary outcomes evaluated in the study. Material and

15. Frequency of Cervical Nodal Metastasis in Early- Stage Squamous Cell Carcinoma of the Tongue
Abstract Introduction Oral cavity carcinoma is an aggressive tumor, with the tongue being one of the most common subsites of involvement. Surgery is a gold standardmethod of dealing with advanced-stage tumors. However, for early-stage carcinomas of the tongue, the management remains controversial. Several studies have indicated that early-stage cancers hav

16. The demographic features, clinical outcomes, prognosis and treatment options for patients with sarcomatoid carcinoma of the urinary bladder: a single centre experience
ABSTRACT Introduction Carcinosarcoma of the bladder is a very rare neoplasm. The pathogenesis of carcinosarcomas is not clearly understood and remains a subject of debate. Whilst there is some research conceptualizing the histopathological findings of bladder carcinosarcomas, the demographic features, clinical outcomes, prognosis and treatment options remai

17. Stress-Based Finite Element Methods for Dynamics Analysis of Euler-Bernoulli Beams with Various Boundary Conditions
Abstract In this research, two stress-based finite element methods including the curvature-based finite element method (CFE) and the curvature-derivative-based finite element method (CDFE) are developed for dynamics analysis of Euler-Bernoulli beams with different boundary conditions. In CFE, the curvature distribution of the Euler-Bernoulli beams is approxi

18. Relationship of Tumor Thickness with Neck Node Metastasis in Buccal Squamous Cell Carcinoma: An Experience at a Tertiary Care Hospital
Abstract Introduction Squamous cell carcinoma is the most common malignancy of the head and neck, with the buccal mucosa being the most common site involved. Early locoregional metastasis is a hallmark of this disease, and early stage tumors may harbor metastatic nodes that are occult. Certain parameters can help identify high-risk patients for whom the pa

19. Role of Monocyte Count and Neutrophil-to- Lymphocyte Ratio in Survival of Oral Cancer Patients
Abstract Introduction Inflammation seems to play a critical role in the development and progression of numerous cancers. Peripheral blood leukocyte count is an easily assessable parameter of systemic inflammatory response. Objective The aim of this study was to investigate whether the pretreatment leukocyte counts can predict the prognosis of patients wi

20. A novel model to estimate lymph node metastasis in endometrial cancer patients
OBJECTIVES: To evaluate the postoperative pathological characteristics of hysterectomy specimens, preoperative cancer antigen (CA)-125 levels and imaging modalities in patients with endometrial cancer and to build a risk matrix model to identify and recruit patients for retroperitoneal lymphadenectomy. METHODS: A total of 405 patients undergoing surgical t

21. Quantitative analysis of lymph nodes in neck dissection specimens. Morphologic study
ABSTRACT PURPOSE: To quantify the amount of lymph nodes harvested in modified radical neck dissection. METHODS: Cross-sectional anatomical study conducted in 28 non-preserved cadavers. RESULTS: The mean number of lymph nodes found in each nodal level of the 56 modified radical neck dissections performed were: level IA - 1.5 (95% CI: 1.1 - 1.8), level I

22. Is [F-18]-fluorodeoxyglucose FDG-PET/CT better than ct alone for the preoperative lymph node staging of muscle invasive bladder cancer?
ABSTRACT Objective: To evaluate whether the use of [F-18]-FDG-PET/CT can accurately predict pelvic lymph node metastasis in patients with muscle invasive TCC of the bladder undergoing radical cystectomy. Materials and Methods: Fifteen patients with muscle invasive bladder cancer had undergone FDG-PET/CT scan from the skull base to the mid-thighs after IV i

23. Robot-Assisted Extended Pelvic Lymph Nodes Dissection for Prostate Cancer: Personal Surgical Technique and Outcomes
Objective: Extended pelvic lymph nodes dissection (EPLND) allows the removal of a higher number of lymph nodes than limited PLND. The aims of this study were to describe our robot-assisted EPLND (RAEPLND) technique with related complications, and to report the number of lymph nodes removed and the rate of lymph nodal metastasis. Materials and Methods: 153

24. Numeric reconstruction of 2D cellular actomyosin network from substrate displacement
Introduction: One of the fundamental structural elements of the cell is the cytoskeleton. Along with myosin, actin microfilaments are responsible for cellular contractions, and their organization may be related to pathological changes in myocardial tissue. Due to the complexity of factors involved, numerical modeling of the cytoskeleton has the potential to
