Focusing on tumor and it's microenvironmental immune members for head and neck cancer patients.

Objective: Immune-related gene expression levels in the tumor microenvironment (TM) of head and neck squamous cell carcinoma (HNSCC) patients was compared.

Materials And Methods: The CD163, CD274, CD86, FUT4, FOXP3, and ITGAX levels of HNSCC patients in their tumor tissues (n =76) and surrounding tissues adjacent to the tumor (n =76) were determined using quantitative real-time PCR (qRT-PCR). Changes in these genes were also evaluated by associating with demographical data of the patients.

Evaluation of the factors affecting the necessity for revision surgery in choanal atresia.

Objective: This study aims to compare the effects of different surgical techniques for congenital choanal atresia (CCA), and particular emphasis is given to the analysis of the factors affecting the surgical outcome. The necessity for revision surgery and surgical outcomes were retrospectively investigated in patients undergoing revision surgery according to a recently proposed classification system.

Material And Method: A retrospective study was conducted on patients operated for CCA between January 2007 and December 2018 at a university hospital.

Chloramphenicol and sulfonamide residues in sea bream (Sparus aurata) and sea bass (Dicentrarchus labrax) fish from aquaculture farm.

There are many worries about the food safety of seafood contaminated with antibiotic residues. These residues can be potentially dangerous for public health owing to the causation of allergic reactions, toxic effects, and serious health problems. This study was planned to search the occurrence of chloramphenicol (CAP) and sulfonamide residue in sea bream and sea bass.

The Simplified Nasal Septal Deviation Evaluation System and Nasal Obstruction Symptom Evaluation Scale Correlation.

Nasal septal deviation (NSD) is a common condition in otorhinolaryngology practice. The aim of this study was to investigate the possible relationship between localization and severity of NSD, and related complaints as well as to suggest a simplified assessment method for NSD. Seventy-five patients who complaint nasal obstruction were enrolled this study.

A 2D mathematical model for tumor angiogenesis: The roles of certain cells in the extra cellular matrix.

We present a 2D mathematical model of tumor angiogenesis which is an extension of the 1D model originally presented in Levine et al. (2000) [1]. Our model is connected to that 1D model by some transmission and boundary conditions which carry certain cells, the endothelials, pericytes and macrophages from the vessel wall into the extra cellular matrix.
