Percutaneous Sacroiliac Screw Fixation: A Modified Screw Insertion Method Using Just 2 Fluoroscopy Views.

Objectives: Percutaneous sacroiliac screw fixation (PSSF) is a well-defined method of surgery to fix unstable fractures of the pelvic ring with fewer post-surgical complications. However, the complex anatomy of the mentioned area makes PSSF a formidable challenge. The present study aimed to investigate a modified screw insertion method using two views of fluoroscopy X-ray instead of the prior three views to reduce the duration of operations and radiation exposures.

Osteogenic Differentiation Effect of BMP-9 with Phenamil and Simvastatin on Intact Human Amniotic Epithelial Stem Cells.

Background: Background: Bone tissue engineering has shown to be a promising strategy for repairing bone defects without causing harmful side effects to the patient. Three main building blocks of tissue engineering, including seeding cells, scaffold, and signaling molecules, are required for adequate bone regeneration. The human amniotic membrane (hAM) is the innermost of the placental membranes.

Objectives: The present study aimed to evaluate the presence of any relationship between vitamin D and prognostic factors among patients infected with SARS-CoV-2.

Methods: This retrospective cross-sectional study was conducted among patients admitted from March to August 2020 in a referral hospital, Tehran, Iran. All patients aged 18-65 who had not any comorbidity participated in the study.

Supplementation with vitamin D and insulin homeostasis in healthy overweight and obese adults: A randomized clinical trial.

Introduction: Hypovitaminosis D which is a frequent problem in overweight and obese individuals, seems to interfere with cells responsible for control of glycemic status. Therefore, the current research intended to study the impact of supplementation with vitamin D on insulin homeostasis among healthy obese and overweight individuals.

Methods: The current study was conducted among obese or overweight individuals who had hypovitaminosis D.
