The aim of this study was to investigate the roles of the transcription factor Snail and adhesion factor epithelial-cadherin (E-cadherin) in clear cell renal cell carcinoma (CCRCC) and evaluate their correlation with tumor pathological grading, clinical stage, invasion and metastases. The expression of Snail and E-cadherin protein in 69 samples of CCRCC tissue, 58 samples of para-cancerous muco...

A patient with chemo-refractory multiple-metastatic upper tract urothelial carcinoma (UTUC) treated by monotherapy with autologous formalin-fixed tumor vaccine (AFTV) resulted in complete remission of the lung and para-aortic lymph node metastases (ongoing >3 years after AFTV). The tumor was immunohistologically negative for PD-L1. AFTV will be an attractive treatment option.

The removal of impacted maxillary third molars is one of the most common procedures performed in oral and maxillofacial surgery units with low rates of complications and morbidity. A few cases of accidental displacement of third molars into adjacent anatomical spaces, such as the infratemporal fossa, the pterygomandibular space, the maxillary sinus, buccal space, or the lateral pharyngeal space...

Gastrointestinal mesenchymal tumors comprise a rare group of gastrointestinal tract wall tumors that have long been a source of confusion and controversy, especially in terms of pathological classification, preoperative diagnosis, management strategies, and prognosis. This report describes the clinical manifestations and management of 2 rectal leiomyomas and reviews the pertinent literature. Ca...

The radiobiological effects of high atomic number and energy (HZE particles) ion beams are of interest for radioprotection in space and tumor radiotherapy. Space radiation mainly consists of heavy charged particles from protons to iron ions, which is distinct from common terrestrial forms of radiation. HZE particles pose a significant cancer risk to astronauts on prolonged space missions. With ...

BACKGROUND Lymph node metastasis is the mayor cause of mortality in patients with head and neck squamous cell carcinomas (45%). The genetic changes underlying metastasis are still largely unknown and genetic markers to predict lymph node positivity still need to be found. The aim of this study was to search such markers by using Multiplex Ligation-dependent Probe Amplification (MLPA), a semi-qu...

PurposeThe relationship between pharyngeal airway morphology and jawbone movements in skeletal Class III patients with mandibular asymmetry after orthognathic surgery remains unclear. This study was to measure the changes bimaxillary evaluate associations movements.MethodsIn this retrospective cohort study, who underwent were enrolled. The predictor variable facial symmetry status divided into ...

We present a study of electromagnetic attenuation over different environments of Mexico City, for an empirical modification of Free Space Attenuation (FSA). Our work uses results of in-site measurements in different places in the city. We intend to measure attenuation in different places to compare and validate modification of FSA. Even we are working in different communications standards, we p...

BACKGROUND The aim of this study was to determine the value of upper and lower pharyngeal depth among patients with skeletal Class III malocclusion on lateral cephalograms, as well as to examine the relationship between SNA, SNB, and ANB angles, along with Wits appraisal and the cross-sectional value of upper airway space at the level of the soft palate and tongue base among patients with skele...

This is an observational study to determine the most relevant parameter of ¹⁸F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) for predicting recurrence in cervical cancer. Fifty-six patients with International Federation of Gynecology and Obstetrics (FIGO) stage IIB-IVA cervical cancer who underwent pretreatment ¹⁸F-FDG PET/CT were enrolled. PET parameters in...
