Pronated foot, as one of the common foot abnormalities can affect the biomechanics of the lower extremity. The purpose of the present study was to investigate the scientific research related to the application of various exercise protocols on foot pronation complications, as well as to make favorable summary and provide more appropriate information from previous research. In this study, the search for articles in Persian and Latin languages in 2019-2022 was carried out on WOS, Magiran, PubMed, Springer databases, and Google Scholar. The number of 52 related articles was selected based on the inclusion and exclusion criteria. After another review on these papers, 18 articles that evaluated the effects of training protocols on body mechanics in individuals with pronated feet were selected.

It seems that performing exercise to improve balance, strengthening the quadriceps muscles, and not change the lower extremity joints angles during activity has been effective. Therefore, it is suggested that rehabilitation professionals consider reinforcement activities in the process of recovering pronated using the principles and science practice.

Patellofemoral pain syndrome is one of the most common musculoskeletal disorders of the knee area. Previous studies have pointed to the positive effects of exercise. Therefore, it is very important to check the types of exercise protocols for the treatment of this condition. The purpose of the present study was to investigate the scientific framework of research related to the application of various exercise protocols on patellofemoral pain syndrome, as well as to make a favorable summary and provide more appropriate information from previous researches. In this review study, the search for articles in Persian and English languages in 2022 (until November) was carried out on WOS, Magiran, Scopus, Google Scholar, PubMed, and Springer databases. The keywords of patellofemoral pain syndrome, knee and knee rehabilitation were used to extract articles. 100 relevant articles were selected based on inclusion and exclusion criteria. After reviewing 100 articles, the number of 53 article titles that were close to the research title met the criteria for inclusion in the present study. After re-examining the articles, 25 articles were selected with the aim of examining the exercise protocol on patellofemoral pain.

It seems that sports exercises with the aim of strengthening the muscles around the knee joint are effective in the recovery process and reducing the pain of people suffering from patellofemoral syndrome.

Coronary artery disease is the most important cause of death due to cardiovascular diseases and the main treatment is angioplasty. The purpose of this study was to evaluate the results of angioplasty in patients based on angiographic results, SYNTAX score, clinical conditions, cardiovascular risk factors and non-invasive tests. Additionally, the matching of angioplasty procedure with clinical guidelines was investigated.
This was a cross-sectional study on 2297 patients referred to cardiac centers in Isfahan City (Chamran, Sina, Sepahan, Saadi, and Shahid Sadughi), Iran, for angioplasty during the second half of the year 2015. Demographic data, history of diabetes, hypertension, or hyperlipidemia, family history of heart disease, and current use of cigarettes were recorded. The extension of coronary artery disease was assessed using SYNTAX score.
Findings: Among 2297 patients, 1577 (69.1%) were men and 706 (30.9%) were women. In 87% of patients, angioplasty was performed according to the guideline; and in 13% of them, open heart surgery or medical treatment was appropriate treatment instead of angioplasty. Significant correlation between the extent of coronary artery disease and the risk factors as age, diabetes, and hyperlipidemia was observed based on SYNTAX score system.
In patients undergoing coronary angiography, SYNTAX score has an acceptable value in association with heart risk factors to demonstrate the generalizability of this association. A prospective cohort study can be used as a way to risk assessment for the patients and selection of appropriate diagnostic or medical strategy.

Ever-increasing use of dental implants and the changes they have brought about in patients’ lives have prompted many studies on dental implants. The aim of this study was to investigate the effect of a 100-mpascal force at different load angles on stress distribution in implant‒jaw assembly, using finite element analysis.
In this experimental analytical study, a three dimensional model consisting of the mandible and a narrow-neck ITI implant was used. Peri-implant stress was evaluated at three points of A (implant neck), B (the middle of the implant) and C (implant apex). The load was applied from 0° to 30° on the implant with a 5° increase rate of the angle. Analysis of data was carried out with one-way ANOVA and Friedman test (α = 0.05).
Increasing the angle of load from 0W to 30° increased the stress around the implant. At all the angles the amount of stress in the implant neck was higher than the middle area, which in turn was higher than the apical area.
An increase in the load angle resulted in the highest amount of stress in the implant neck, i.e. the closest area to the force application site and away from the center of resistance, with the least stress in the apical area.
