Side Effects of COVID-19 Vaccination Following First and Second Doses: A Cross-Sectional Survey Based on Vaccine-associated Factors.

Background: Due to the rapid launch and development of vaccines (the most ideal protocol for countering COVID-19), monitoring of post-vaccination side effects is essential. This study aimed to assess symptoms and side effects of three types of COVID-19 vaccines (Sputnik, AstraZeneca, and Sinopharm) and the details of their relationship with demographic characteristics in Iran.

Materials And Methods: A cross-sectional and telephonic interview-based study was conducted from May 12 to July 11, 2021, among 420 university staff who received both doses of the COVID-19 vaccine.

COVID-19 vaccines breakthrough infection and adverse reactions in medical students: a nationwide survey in Iran.

Introduction: There are different types of COVID-19 vaccines approved worldwide. Since no national studies focus on vaccine-related adverse reactions and breakthrough cases, this study aimed to investigate the rate of adverse events and COVID-19 infection in medical students in Iran.

Methods: This retrospective cohort study included Iranian medical students who received two doses of COVID-19 vaccines.

Evaluations of Factors Affecting of Short-and Long-Time of Occurrence of Disease Relapse in Patients with Tuberculosis Using Parametric Mixture Cure Model: A Cohort Study.

Background: The success of treatment strategies to control the disease relapse requires determining factors affecting the incident short-time and long-time of disease relapse. Therefore, this study was aimed to identify the factors affecting of short-and long-time of occurrence of disease relapse in patients with tuberculosis (TB) using a parametric mixture cure model.

Materials And Methods: In this historical cohort study; the data was collected from 4564 patients with TB who referred to the Tuberculosis and Lung Diseases Research Center of Dr.

An Investigation of Post-radiation Gene Expression Profiles: A System Biology Study.

Genomics and bioinformatics are useful methods for exploring unclear aspects of radiation effects on biological systems. Many radiation-induced alterations in irradiated samples are post-radiation time-dependent. This study aims to evaluate the post-irradiation effects of the gamma ray on human Jurkat cells.

Introducing GATA3 as a prominent player in Crohn's disease.

Aim: This study was aimed at gene assessment of Crohn's disease (CD) through protein-protein interaction (PPI) network analysis to find crucial genes.

Background: CD is a major subtype of inflammatory bowel diseases (IBD), which affects gastrointestinal tract. PPI network analysis is a suitable tool to clarify a critical gene as a drug target or diagnostic biomarker for these types of diseases.

Nanomaterials for food packaging applications: A systematic review.

The application of nanotechnology in food packaging is widely considered during the last two decades. In this regard, numerous studies have been conducted regarding applying nanomaterials such as zinc oxide, clay, silver, carbon nanotube, titanium dioxide, and copper, and copper oxide in food packaging which were summarized in the current study. The employing of nano food packaging increases the physicochemical quality of food (color, flavor, moisture content, weight, bioavailability, and texture) and reduces the microbial load by cell-membrane function, Trojan-horse, and reactive oxygen mechanisms while they improve the barrier/mechanical properties of food packaging.

Sudden Death Following Oral Intake of Metal Objects (Acuphagia): a Case Report.

According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), pica is described as eating one or more non-nutritive, non-food substances over a period of at least 1 month that is severe enough to warrant clinical attention. The present case is a 44-year-old man who was brought to emergency department following severe abdominal pain, but died before admission or receiving any treatments. On the autopsy, 64 bolts and metal fittings (3700 grams) were found in the esophagus, stomach, small intestine, and large intestine of the patient.

Holy month of Ramadan and increase in organ donation willingness.

Organ shortage is the most significant factor in restricting the activities of transplantation systems. We herein report the positive impact of Muslims' holy month of Ramadan on willingness to donate organs in Iran. Data were derived from the database of Donation Willingness Registries, affiliated to the organ procurement unit of Masih Daneshvari Hospital during March 2007 till March 2008.
