Influenza viruses are globally important respiratory pathogens with high degree of morbidity and mortality during annual epidemics. Influenza A vaccination has been challenged due to genetic evolution. M2 protein is the surface antigen of the virus and facilitates virus entry into the host cells. N-terminal 24 amino acid residues that constitute the extracellular domain of M2 protein (M2e) show remarkable conservation among all subtypes of influenza A viruses. The aim of the present study was to investigate the effects of using HSP70 as an adjuvant fused to three tandem repeats of M2e (3M2e) to enhance the immune responses against influenza A challenge...

Objective: Type 1 diabetes mellitus (T1DM) is a chronic immune-mediated disease. Diabetic peripheral neuropathy (DPN) is an important microvascular complication of T1DM. One of the most important risk factors for the development of DPN is poor glycemic control. We evaluated the prevalence of DPN among T1DM patients and determined the association between DPN and glycated hemoglobin (HbA1c) level. Materials & Methods: The subjects were recruited prospectively upon initial evaluation at Imam Reza Hospital, Mashhad, Iran from Jan 2013 to Jan 2015...

In this research, natural nanomaterials including cellulose nanocrystal (CNC), nanofiber cellulose (NFC), and synthetic nanoparticles such as carbon nanofiber (CNF) and carbon nanotube (CNT) with different structures, sizes, and surface areas were produced and analyzed. The most significant contribution of this study is to evaluate and compare these nanomaterials based on the effects of their structures and morphologies on their electrochemical, biomedical, and thermal properties. Based on the obtained results, the natural nanomaterials with low dimension and surface area have zero cytotoxicity effects on the living cells at 12...

Due to critical impacts of air pollution, prediction and monitoring of air quality in urban areas are important tasks. However, because of the dynamic nature and high spatio-temporal variability, prediction of the air pollutant concentrations is a complex spatio-temporal problem. Distribution of pollutant concentration is influenced by various factors such as the historical pollution data and weather conditions. Conventional methods such as the support vector machine (SVM) or artificial neural networks (ANN) show some deficiencies when huge amount of streaming data have to be analyzed for urban air pollution prediction...

In this research, chitosan nanobiopolymers (CS-NPs) were synthesized using tripoly phosphate and transferred into the organic solvent via solvent exchange method. Different amounts of chitosan nanopolymers were embedded into the polyethersulfone (PES) membrane prepared by phase inversion precipitation method. The membranes were employed for nitrate removal from water under various solution pHs (4.5, 7.0 and 9.0). Scanning electron microscopy, atomic force microscopy, porosity, water contact angle and pure water flux measurements were employed to characterize the fabricated membranes...

OBJECTIVE: We investigated and compared the effects of taraxasterol, aqueous extract of T. officinale (AET) aerial part, and potassium citrate (PC) on calcium oxalate (CaOx) crystallization in vitro. MATERIALS AND METHODS: CaOx crystallization was induced by adding sodium oxalate to synthetic urine. Taraxasterol (2.5, 5, 7.5 and 12.5 μg/mL), extract (1, 2, 4 and 8 mg/mL), and PC (100, 150, 200 and 350 mg/mL) were subjected to anti-crystallization activities...

Proteus mirabilis is one of the most common causes of urinary tract infection (UTI), particularly in patients undergoing long-term catheterization. Phage vB_PmiS-TH was isolated from wastewater with high lytic activity against P. mirabilis (TH) isolated from UTI. The phage had rapid adsorption, a large burst size (∼260 PFU per infected cell), and high stability at a wide range of temperatures and pH values. As analyzed by transmission electron microscopy, phage vB_PmiS-TH had an icosahedral head of ∼87 × 62 nm with a noncontractile tail about 137 nm in length and 11 nm in width...

Non-alcoholic fatty liver disease (NAFLD) is an example of pathological fat accumulation in the liver and one of the major health conditions in the world. This study aimed to examine the independent role of dietary patterns in the development of NAFLD. In a cross-sectional study, 1500 individuals referred to a nutrition clinic were randomly selected, their demographic, anthropometric and blood metabolic indices were obtained, and food frequency questionnaires were completed for them. Liver stiffness was calculated using the NAFLD score formula and fibroscan...

Sulphated carboxymethylcellulose (SCMC) was synthesized and characterized via FT-IR and CHNS analysis. The PES membranes were prepared and modified via surface amination with an aminolysis reaction and amount of amino groups was measured. The carboxymethylcellulose (CMC) and SCMC were immobilized on the surface of the aminated PES membranes (PES-NH2 ) via amide bonds to synthesize PES-CMC and PES-SCMC membranes, respectively, and the concentration of immobilized CMC and SCMC was determined. The unmodified PES, PES-CMC, and PES-SCMC membranes were characterized in terms of morphology, overall porosity, mean pore size, zeta potential, tensile strength, contact angle, protein adsorption and platelet adhesion...

INTRODUCTION: Many patients with bipolar disorder (BD) spend around 10 years without a diagnosis and appropriate treatment. The difficulty in distinguishing bipolar from unipolar depression, the prevalence of depressive symptoms along the course of BD and patients' bias in recalling their hypomanic symptoms are some of the factors that contribute to this problem. OBJECTIVE: This study compares the efficiency of several screening instruments for BD detection in a group of patients (n=63) with mood disorders, or cluster B personality disorders...

Good's syndrome, the adult onset hypogammaglobulinemia associated with thymoma has been explained about six decades ago. It generally presents with recurrent infections and several paraneoplastic syndromes including myasthenia gravis, pure red cell aplasia, connective tissue disorders, superior vena cava, Horner's syndrome, lichen planus and inflammatory bowel disease. Lack of B cell, dysfunction of T cell, CD4+ T cell lymphopenia, reversed CD4/CD8+ T cell ratio, autoantibodies against Th17 related cytokines have been respected as the pathogenesis of the immune dysregulation this syndrome...

BACKGROUND: It has been proposed that the broad major depressive disorder (MDD) construct is heterogenous. Koukopoulos has provided diagnostic criteria for an important subtype within that construct, "mixed depression" (MxD), which encompasses clinical pictures characterized by marked psychomotor or inner excitation and rage/anger, along with severe depression. This study provides psychometric validation for the first rating scale specifically designed to assess MxD symptoms cross-sectionally, the Koukopoulos Mixed Depression Rating Scale (KMDRS)...

We show how to realize two-component fractional quantum Hall phases in monolayer graphene by optically driving the system. A laser is tuned into resonance between two Landau levels, giving rise to an effective tunneling between these two synthetic layers. Remarkably, because of this coupling, the interlayer interaction at nonzero relative angular momentum can become dominant, resembling a hollow-core pseudopotential. In the weak tunneling regime, this interaction favors the formation of singlet states, as we explicitly show by numerical diagonalization, at fillings ν=1/2 and ν=2/3...
