Respiratory Bacterial and Fungal Superinfections During the Third Surge of the COVID-19 Pandemic in Iran.

We characterized bacterial and fungal superinfection and evaluated the antimicrobial resistance profile against the most common superinfection-causing pathogens (, , and ). In a cross-sectional study, 192 respiratory samples were collected from patients with and without SARS-COV-2 admitted to a teaching hospital in Tehran. Superinfection proportions and the antibiotic resistance profile were assessed and compared with demographic, comorbidities, and other clinical factors.

The efficacy comparison of citalopram, fluoxetine, and placebo on motor recovery after ischemic stroke: a double-blind placebo-controlled randomized controlled trial.

Objective: The present study aimed to assess the effectiveness of oral citalopram, compared with fluoxetine and a placebo, in patients with post-stroke motor disabilities.

Design: A randomized double-blind placebo-controlled clinical trial was conducted between January 2015 and January 2016.

Setting: The neurology department of a university-affiliated urban hospital in Tehran, Iran.

Evaluation of Soft Tissue Sarcoma Tumors Electrical Conductivity Anisotropy Using Diffusion Tensor Imaging for Numerical Modeling on Electroporation.

Introduction: There is many ways to assessing the electrical conductivity anisotropy of a tumor. Applying the values of tissue electrical conductivity anisotropy is crucial in numerical modeling of the electric and thermal field distribution in electroporation treatments. This study aims to calculate the tissues electrical conductivity anisotropy in patients with sarcoma tumors using diffusion tensor imaging technique.

Muscle MRI of facioscapulohumeral dystrophy (FSHD): A growing demand and a promising approach.

Facioscapulohumeral muscular dystrophy (FSHD), an inherited and progressive muscle disorder, is among the most common hereditary muscle disorders. From a clinical vantage point, FSHD is characterized by weakness of the facial, shoulder (often with scapular winging), arm (including biceps and triceps) and abdominal muscles. Forearm muscles are usually spared and weakness is usually asymmetrical.

Dietary intake of nutrients and its correlation with fatigue in multiple sclerosis patients.

Background: The role of nutrition in the progression of multiple sclerosis (MS) and related complications such as fatigue has been reported by several studies. The aim of this study is the assessment of nutritional status and its relationship with fatigue in multiple sclerosis patients.

Methods: This is a cross-sectional study, in which 101 relapsing-remitting MS patients were enrolled.

Evidence-based status of osteochondral cylinder transfer techniques: a systematic review of level I and II studies.

Purpose: Our purpose was to examine the Level I and II evidence for the use of osteochondral cylinder transfer technique (OCT) for cartilage repair.

Methods: A literature search was carried out for Level I and II evidence studies on cartilage repair using the PubMed database. All the studies that involved OCT were identified.

Prevention of synkinesis by biofeedback therapy: a randomized clinical trial.

Objective: The aim of present study was to find a better procedure to prevent synkinesis in facial nerve palsy.

Design: A randomized clinical trial.

Setting: Clinical rehabilitation faculty and general rehabilitation centers.

Baló's concentric sclerosis in a girl with interesting presentation.

Balo's concentric multiple scleroses (MS) is a rare demyelinating disease and a variant of multiple sclerosis. We report a case with interesting misleading clinical history and typical RI findings of Balo disease. A 19-year-old girl presented with fever and left hemiparesis following dental procedure 15 days ago.

Fibrillation of alpha-lactalbumin: effect of crocin and safranal, two natural small molecules from Crocus sativus.

Formation of toxic amyloid structures is believed to be associated with various late-onset neurodegenerative disorders such as Alzheimer's and Parkinson's diseases. The fact that many proteins in addition to those that are associated with clinical conditions have the potential to form amyloid fibrils in vitro provides opportunities for studying the fundamentals of protein aggregation and amyloid formation in model systems. Accordingly, considerable interest and effort has been directed toward developing small molecules to inhibit the formation of fibrillar assemblies and their associated toxicities.

Alterations of telomere length in human brain tumors.

Telomeres at the ends of human chromosomes consist of tandem hexametric (TTAGGG)n repeats, which protect them from degradation. At each cycle of cell division, most normal somatic cells lose approximately 50-100 bp of the terminal telomeric repeat DNA. Precise prediction of growth and estimation of the malignant potential of brain tumors require additional markers.
