Investigate the role of positive and negative memories from dentistry in the anxiety of dental patients in Kerman, Iran.

Background And Aim: Several research works show that anxiety is more common in women, low-income classes, and middle-aged and elderly populations. The present study aimed to investigate the role of positive and negative memories in patients' anxiety referred to the dental clinics, offices, and schools of Kerman, Iran, in 2018-2019.

Materials And Methods: In this cross-sectional, descriptive, analytical study, the participants were selected among individuals referred to the dental offices, schools, and clinics of Kerman, Iran.

Characterization of the cylindrical electrospun nanofibrous polysulfone membrane for hemodialysis with modelling approach.

Electrospun nanofibrous membrane (ENM) is a membrane fabricated using electrospinning technique which has considerable characteristics such as high porosity, nanometer pore size, and simple process. Although ENMs are being evaluated in various medical applications, the effectiveness for hemodialysis (HD) has not been evaluated carefully. Thus, in this study, the cylindrical electrospun nanofibrous polysulfone (CENP) membrane was fabricated and its performance in the dialysis adequacy in HD patients was evaluated.

Artificial neural network and logistic regression modelling to characterize COVID-19 infected patients in local areas of Iran.

Background: COVID-19 is an infectious disease that started spreading globally at the end of 2019. Due to differences in patient characteristics and symptoms in different regions, in this research, a comparative study was performed on COVID-19 patients in 6 provinces of Iran. Also, multilayer perceptron (MLP) neural network and Logistic Regression (LR) models were applied for the diagnosis of COVID-19.

Nanofibrous Tubular Membrane for Blood Hemodialysis.

As the most important components of a hemodialysis device, nanofibrous membranes enjoy high interconnected porosity and specific surface area as well as excellect permeability. In this study, a tubular nanofibrous membrane of polysulfone nanofibers was produced via electrospinning method to remove urea and creatinine from urine and blood serums of dialysis patients. Nanofibrous membranes were electrospun at a concentration of 11.
