The frequency of high-risk human papillomavirus types, HPV16 lineages, and their relationship with p16 and NF-κB expression in head and neck squamous cell carcinomas in Southwestern Iran.

High-risk human papillomaviruses (hr-HPVs) are the key risk factors implicated in the development of a significant proportion of head and neck squamous cell carcinomas (HNSCCs). We aimed to investigate the distribution of hr-HPV types and HPV16 lineages in a sample of patients with HNSCC and the possible association between HPV status and the expression of P16INK4A and NF-κB in Iranian HNSCC patients. We examined 108 formalin-fixed, paraffin-embedded (FFPE) histologically confirmed primary SCC tissue specimens of different head and neck anatomical sites.

Investigation of IL-33 serum levels in patients with benign and malignant salivary gland tumors.

Background: Interleukin-33 (IL-33) has been recently discovered as an influential factor in the process of tumor immunity, and is presented in cancer pathogenesis.

Objective: This study aimed to determine the serum levels of IL-33 in patients with benign and malignant Salivary gland tumors (SGTs).

Methods: This descriptive cross-sectional study was performed on 47 samples of malignant SGTs including 18 mucoepidermoid carcinoma (MEC), 8 adenoid cystic carcinoma (ADCC), 21 malignant mixed tumor (MMT), and 14 benign pleomorphic adenoma (PA).

Serum Endostatin Levels in Oral Squamous Cell Carcinoma.

Introduction: Endostatin is a C-terminal proteolytic fragment of collagen XVIII and, as with angiostatin and thrombospondin, is known as an antiangiogenic agent. The aim of this study was to assess the level of serum endostatin in patients with oral squamous cell carcinoma (SCC), and its association with the clinicopathological characteristics of the tumor.

Materials And Methods: Using an enzyme-linked immunosorbent assay (ELISA) kit, we investigated the circulating levels of endostatin in the blood serum of 45 patients with oral SCC and 45 healthy controls.

Biochemical, hematological, and pathological related healing effects of Elaeagnus angustifolia hydroalcoholic extract in 5-fluorouracil-induced oral mucositis in male golden hamster.

Oral mucositis (OM) is one of the cancer chemotherapy-related side effects which can affect the quality of life of affected patients. This study was designed to investigate the healing effect of Elaeagnus angustifolia in 5-flurouracil (5-FU)-induced OM in golden hamster. Fifty-six adult male golden hamsters received three intraperitoneal injections of 5-FU at a dose of 60 mg/kg on days 0, 5, and 10.

Topical Olive Leaf Extract Improves Healing of Oral Mucositis in Golden Hamsters.

Statement Of The Problem: Oral mucositis (OM) is a common side effect of anti-cancer drugs and needs significant attention for its prevention.

Purpose: This study aimed to evaluate the healing effects of olive leaf extract on 5-fluorouracil-induced OM in golden hamster.

Materials And Method: OM was induced in 63 male golden hamsters by the combination of 5-fluorouracil injections (days 0, 5 and 10) and the abrasion of the cheek pouch (days 3 and 4).

MCM3 as a novel diagnostic marker in benign and malignant salivary gland tumors.

Background: Proliferation markers widely have been used to diagnose and determine the behaviour and prognosis of benign and malignant tumours. Minichromosome maintenance 3 (MCM3) is a novel proliferation marker. The aim of this study was to evaluate and compare MCM3 with Ki-67 in diagnosis of salivary gland tumours.
