Morphological data is included based on the latest international gastroenterology classification references such as Paris, Pit and JNET classification. Pathological data includes the diagnosis of the polyps including Tubular, Villous, Tubulovillous, Hyperplastic, Serrated, Inflammatory and Adenocarcinoma with Dysplasia Grade & Differentiation.

Extracellular vesicles and cancer stem cells: a deadly duo in tumor progression.

The global incidence of cancer is increasing, with estimates suggesting that there will be 26 million new cases and 17 million deaths per year by 2030. Cancer stem cells (CSCs) and extracellular vesicles (EVs) are key to the resistance and advancement of cancer. They play a crucial role in tumor dynamics and resistance to therapy.

Safety evaluation of the trastuzumab biosimilar in Iranian women with HER2-positive breast cancer undergoing adjuvant chemotherapy: a post-marketing surveillance.

Background: Trastuzumab is a humanized monoclonal antibody against the human epidermal growth factor receptor 2 (HER2). This post-marketing surveillance evaluates the safety of a trastuzumab biosimilar (AryoTrust), produced by AryoGen Co. Iran in Iranian women with HER2-positive non-metastatic breast cancer (BC).

The investigation of the frequency of COVID-19 in patients with a history of stroke.

Introduction: The emergence of the coronavirus in 2019 became a global epidemic disease. According to the World Health Organization, people with a history of chronic diseases such as brain stroke are among the main groups at risk of contracting COVID-19. Therefore, this study was performed with the aim of the determination amount of the frequency of contracting COVID-19 in stroke patients.

DNA Damage Responses, the Trump Card of Stem Cells in the Survival Game.

Stem cells, as a group of undifferentiated cells, are enriched with self-renewal and high proliferative capacity, which have attracted the attention of many researchers as a promising approach in the treatment of many diseases over the past years. However, from the cellular and molecular point of view, the DNA repair system is one of the biggest challenges in achieving therapeutic goals through stem cell technology. DNA repair mechanisms are an advantage for stem cells that are constantly multiplying to deal with various types of DNA damage.

The Impact of COVID-19 on Cancer Recurrence: A Narrative Review.

Severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) continues to be a worldwide healthcare problem. While our knowledge of the interaction of cancer and its management with COVID-19 mortality is gradually evolving, there are still many unanswered questions regarding the impact of COVID-19 on cancer and its prognosis. Several factors activated during COVID-19 have been implicated in tumorigenesis and the development of metastasis.

Brown adipose tissue and alzheimer's disease.

Alzheimer's disease (AD), the most common type of senile dementia, is a chronic neurodegenerative disease characterized by cognitive dysfunction and behavioral disability. The two histopathological hallmarks in this disease are the extraneuronal accumulation of amyloid-β (Aβ) and the intraneuronal deposition of neurofibrillary tangles (NFTs). Despite this, central and peripheral metabolic dysfunction, such as abnormal brain signaling, insulin resistance, inflammation, and impaired glucose utilization, have been indicated to be correlated with AD.

Application of Biocompatible Scaffolds in Stem-Cell-Based Dental Tissue Engineering.

Tissue engineering as an important field in regenerative medicine is a promising therapeutic approach to replace or regenerate injured tissues. It consists of three vital steps including the selection of suitable cells, formation of 3d scaffolds, and adding growth factors. Mesenchymal stem cells (MSCs) and embryonic stem cells (ESCs) are mentioned as two main sources for this approach that have been used for the treatment of various types of disorders.

The Incidence of Deep Vein Thrombosis in Breast Cancer Patients Receiving Outpatient Cancer Therapy in Iran.

Background: Venous thromboembolism (VTE) is one of the main causes of mortality in patients with cancer. This study was conducted to assess the incidence of deep vein thrombosis (DVT) in breast cancer patients receiving outpatient cancer therapy.

Materials And Methods: This multi-center prospective cohort study was conducted on patients with breast cancer, initiating an outpatient chemotherapy regimen in five medical centers in Iran.

Effect of Processed Honey and Royal Jelly on Cancer-Related Fatigue: A Double-Blind Randomized Clinical Trial.

Background: Cancer-related fatigue (CRF) is experienced by 50% to 90% of cancer patients and can severely affect their quality of life and functional capacity. Several randomized trials have recommended various ways to alleviate the symptoms of CRF with or without recourse to medications.

Objective: The aim of this study is to evaluate the effectiveness of processed honey and royal jelly on the symptoms of CRF in cancer patients who are undergoing hormone therapy, chemotherapy, chemo-radiation, or radiotherapy.

Efficacy of benzydamine oral rinse in prevention and management of radiation-induced oral mucositis: A double-blind placebo-controlled randomized clinical trial.

Aim: Several studies have demonstrated positive effects of benzydamine oral rinse in prevention of radiation-induced oral mucositis. The aim of this study was to assess the efficacy of this medication in reducing the signs and symptoms of oral mucositis in patients receiving radiotherapy for head and neck cancer.

Methods: Fifty-one patients with head and neck carcinoma 2012 received external beam radiotherapy for 5 days/week to total planned cumulative radiotherapy doses of at least 5000 cGy.

Attitude of cancer patients toward diagnosis disclosure and their preference for clinical decision-making: a national survey.

Objectives: There is still contradictory evidence on disclosure preferences regarding cancer diagnosis. The aim of this study was to evaluate the preference of cancer patients for knowing the truth about their disease, as well as the factors that might have an impact on these preferences.

Method: This study was conducted in 11 cancer centers in Iran.

Quality of life among veterans with war-related unilateral lower extremity amputation: a long-term survey in a prosthesis center in Iran.

Objective: To determine the factors that have an adverse effect on the long-term health-related quality of life (HRQOL) of veterans who have lost their extremities on the battlefield.

Design: Cross-sectional study.

Setting: Tertiary prosthesis center.

A very rare case of single coronary artery anomaly, with left anterior descending and left circumflex arteries originating separately from proximal right coronary artery.

Coronary artery anomalies are rare, with the reported prevalence of 0.2% to 1% in routine angiographic studies. Among them, presence of a single coronary artery is one of the rarest anomalies, comprising less than 3% of all coronary anomalies.
