Health Anxiety among Nurses Caring for Patients with Covid-19.

Background: Medical personnel, especially nurses, are at the forefront of the global COVID-19 epidemic. This study was conducted with the aim to evaluate the level of health anxiety in nurses caring for patients with COVID-19.

Materials And Methods: This cross-sectional, descriptive study was performed on the 340 nurses working in 3 selected educational and medical centers affiliated with Zanjan University of Medical Sciences, Iran.

An experimental investigation on the influence of various buffer concentrations, osmolytes and gold nanoparticles on lysozyme: Spectroscopic and calorimetric study.

Considering importance and several industrial applications of lysozyme, including natural antibiotic and preservative, identifier for the diagnosis of diseases, and extraction purposes, its reversibility and stability studies can be very important. In this paper, the role that buffer and osmolytes concentrations play on the thermodynamic stability of lysozyme denaturation process, that is a new simple and inexpensive method, was evaluated by Nano-DSC III, far- and near-UV CD and fluorescence techniques. In thermal denaturation study, RI and ΔG of protein increased from 25.

Survival prediction of gastric cancer patients by Artificial Neural Network model.

Aim: This study aims to predict survival rate of gastric cancer patients and identify the effective factors related to it, using artificial neural network model.

Background: Gastric cancer is the most deadly disease in north and northeast provinces of Iran. A total of 430 patients with gastric cancer who referred to Baghban clinic in Sari, from early November 2006 to late October 2013 were followed.

Treatment Delay and Total Delay among Pulmonary Tuberculosis Patients in the North of Iran: Application Survival Data Analysis.

Background: Tuberculosis (TB) remains the leading cause of death among infectious diseases worldwide. Identifying the factors associated with the treatment delay and total delay would be helpful in the prevention of tuberculosis and in reducing the burden on the health care system. The objective of this study was to assess the treatment delay and total delay in TB patients and investigate the factors causing these delays.
