Giant axonal neuropathy: a rare inherited neuropathy with a novel mutation.

We present a 7.5-year-old boy born to a family from the Iranian Azeri Turkish ethnic group with a consanguineous marriage who presents with a unique set of symptoms, suggesting Giant Axonal Neuropathy. He achieved independent walking at age 3 years, with frequent falling during running.

A dandelion structure of eigenvector preferential attachment networks.

In this paper we introduce a new type of preferential attachment network, the growth of which is based on the eigenvector centrality. In this network, the agents attach most probably to the nodes with larger eigenvector centrality which represents that the agent has stronger connections. A new network is presented, namely a dandelion network, which shares some properties of star-like structure and also a hierarchical network.

Electromagnetic informed data model considerations for near-field DOA and range estimates.

Localizing sources in the near-field is one of the emerging challenges for array signal processing, which has received a great deal of attention in recent years. The development of accurate localization algorithms requires the definition of a reliable model of the received signal that takes into account all wavefront characteristics, such as angle, range, and polarization, as well as electromagnetic effects, such as mutual coupling between antennas and the amplitude and phase behaviour of electromagnetic wavefronts. A system model that considers the electromagnetic-informed wave behaviour effects, independent of the type of receiver antennas, array structure, degree of correlation of sources signals and other electromagnetic effects, is considered an " exact model " in the literature.

Exploring the relationship between disability status, depression, and quality of life in individuals with multiple sclerosis.

Introduction: Depression and the presence of a disability emerge as noteworthy predictors of the quality of life (QoL) in patients with multiple sclerosis (MS). In this article, we explore the relationship between disability status, depression, and quality of life in individuals with multiple sclerosis.

Methods: A total of 150 patients participated in this cross-sectional study.

Iranian specialists' approach to surgery in patients with multiple sclerosis.

Data on perioperative risk stratification in patients with multiple sclerosis (MS) are limited. In this regard, the present study was conducted to investigate Iranian specialists' approach to surgical counseling for patients with MS (PwMS). 21 MS specialists were asked about 11 case scenarios with different MS disease statuses, disease-modifying therapies (DMTs), and urgency of the operation.

Iranian specialists' approach to treatment escalation in multiple sclerosis patients with cognitive impairment.

People with multiple sclerosis ‎(MS) and their physicians recognize cognitive retention as an important desired outcome of disease-modifying therapies (DMTs). In this study, we attempted to gather the opinions of Iranian MS experts regarding the treatment approach toward clinical cases with different physical and cognitive conditions. Opinions of 20 MS specialists regarding the best approach to 6 case scenarios (with different clinical, cognitive, and imaging characteristics) were gathered via a form.

Gut microbiome in multiple sclerosis-related cognitive impairment.

Cognition is one of the most evaluated neurologic subjects with which the gut microbiome is supposed to be associated. Cognitive impairment is a prevalent finding in patients with multiple sclerosis (MS). Here, we are about to study the current evidence on the effect of gut microbiota on cognition and MS.

Clinical characteristics of 365 hospitalized COVID-19 patients with neurological symptoms: an observational study.

Objective: Since the beginning of the COVID-19 pandemic, a number of COVID-related neurological manifestations have been reported. We aimed to categorize the features of hospitalized COVID-19 patients who experienced neurological symptoms.

Methods: In this descriptive, cross-sectional study, we enrolled all patients hospitalized with COVID-19 who experienced neurological symptoms in two hospitals in Tehran.

Evaluation of the properties and antibacterial activity of microchitosan film impregnated with Shirazi thyme () and garlic () essential oils.

Background: Recent research has shown that chitosan has good moisture-absorbing properties at the micro and nanoscale, and seems to be a good candidate for the production of biodegradable moisture-absorbing films.

Aims: The aim of this study was to evaluate the properties and antibacterial activity of starch-based microchitosan (MCH) films impregnated with two essential oils (EOs).

Methods: MCH films with varying thicknesses were made from cornstarch (6%), microchitosan (1%), glycerol (2.

Captopril and Spironolactone can Attenuate Diabetic Nephropathy in Wistar Rats by Targeting ABCA1 and microRNA-33.

Background: Nephropathy diabetes is one of the important causes of death and a more prevalent cause of end-stage renal disease.

Objective: The present study investigated the effect of applying spironolactone and captopril and their combination on some renal performance indices and cholesterol-efflux-related gene expression in nephropathy diabetic rats.

Methods: Intraperitoneal injection of streptozotocin was used to induce diabetes in rats.

Self-similar but not conformally invariant traces obtained by modified Loewner forces.

The two-dimensional Loewner exploration process is generalized to the case where the random force is self-similar with positively correlated increments. We model this random force by a fractional Brownian motion with Hurst exponent H≥1/2≡H_{BM}, where H_{BM} stands for the one-dimensional Brownian motion. By manipulating the deterministic force, we design a scale-invariant equation describing self-similar traces which lack conformal invariance.

Fatigue in patients with chronic disease: results from the population-based Lifelines Cohort Study.

(1) To evaluate the prevalence of severe and chronic fatigue in subjects with and without chronic disease; (2) to assess to which extent multi-morbidity contributes to severe and chronic fatigue; and (3) to identify predisposing and associated factors for severe and chronic fatigue and whether these are disease-specific, trans-diagnostic, or generic. The Dutch Lifelines cohort was used, including 78,363 subjects with (n = 31,039, 53 ± 12 years, 33% male) and without (n = 47,324, 48 ± 12 years, 46% male) ≥ 1 of 23 chronic diseases. Fatigue was assessed with the Checklist Individual Strength-Fatigue.

Superstatistical two-temperature Ising model.

The previous approach of the nonequilibrium Ising model was based on the local temperature in which each site or part of the system has its own specific temperature. We introduce an approach of the two-temperature Ising model as a prototype of the superstatistic critical phenomena. The model is described by two temperatures (T_{1},T_{2}) in a zero magnetic field.

The prevalence and related factors of fatigue in patients with COPD: a systematic review.

Background: Fatigue is a distressing symptom in patients with COPD. Little is known about the factors that contribute to fatigue in COPD. This review summarises existing knowledge on the prevalence of fatigue, factors related to fatigue and the instruments most commonly used to assess fatigue in COPD.
