StxB fusion strategy for immunogenic enhancement: Recombinant expression of AcAMP antimicrobial peptide.

Influences of RASopathies on Neuroanatomical Variation in Children.

Background: RASopathies are a group of disorders characterized by pathogenic mutations in the Ras/mitogen-activated protein kinase (Ras/MAPK) signaling pathway. Distinct pathogenic variants in genes encoding proteins in the Ras/MAPK pathway cause Noonan syndrome (NS) and neurofibromatosis type 1 (NF1), which are associated with increased risk for autism spectrum disorder and attention-deficit/hyperactivity disorder.

Methods: This study examined the effect of RASopathies (NS and NF1) on human neuroanatomy, specifically on surface area (SA), cortical thickness (CT), and subcortical volumes.

Mode decomposition-based time-varying phase synchronization for fMRI.

Recently, there has been significant interest in measuring time-varying functional connectivity (TVC) between different brain regions using resting-state functional magnetic resonance imaging (rs-fMRI) data. One way to assess the relationship between signals from different brain regions is to measure their phase synchronization (PS) across time. However, this requires the a priori choice of type and cut-off frequencies for the bandpass filter needed to perform the analysis.

Response of Saponaria officinalis L. hairy roots to the application of TiO nanoparticles in terms of production of valuable polyphenolic compounds and SO6 protein.

Saponaria officinalis L. is a perennial plant from the Caryophyllaceae family whose various parts are used in traditional medicine as the treatment agent of skin diseases, blood purifier, diuretic, sudorific, and bile purifier. The cultivation system of hairy roots is a proper alternative for improving the valuable pharmaceutical compounds production compared to other in-vitro methods.

Dynamic Functional Brain Connectivity Underlying Temporal Summation of Pain in Fibromyalgia.

Objective: Abnormal central pain processing is a leading cause of pain in fibromyalgia (FM) and is perceptually characterized with the psychophysical measure of temporal summation of pain (TSP). TSP is the perception of increasingly greater pain in response to repetitive or tonic noxious stimuli. Previous neuroimaging studies have used static (i.

Immunological detection of AcAMP antimicrobial peptide secreted by .

Background And Objectives: antimicrobial peptide (AcAMP) is a fungi-derived peptide with a broad spectrum of activity against pathogenic bacteria and fungi. Natural antimicrobial peptides, including AcAMP, have attracted many attentions in the development of new natural antibiotics against pathogenic bacteria, especially multidrug resistant ones.

Materials And Methods: In the present study, gene was codon-optimized and chemically synthesized in pUC57 cloning vector, subcloned into pET28a (+) expression vector and transferred into competent BL21 (DE3) cells.

Phase-locking of resting-state brain networks with the gastric basal electrical rhythm.

A network of myenteric interstitial cells of Cajal in the corpus of the stomach serves as its "pacemaker", continuously generating a ca 0.05 Hz electrical slow wave, which is transmitted to the brain chiefly by vagal afferents. A recent study combining resting-state functional MRI (rsfMRI) with concurrent surface electrogastrography (EGG), with cutaneous electrodes placed on the epigastrium, found 12 brain regions with activity that was significantly phase-locked with this gastric basal electrical rhythm.

Evaluating phase synchronization methods in fMRI: A comparison study and new approaches.

In recent years there has been growing interest in measuring time-varying functional connectivity between different brain regions using resting-state functional magnetic resonance imaging (rs-fMRI) data. One way to assess the relationship between signals from different brain regions is to measure their phase synchronization (PS) across time. There are several ways to perform such analyses, and we compare methods that utilize a PS metric together with a sliding window, referred to here as windowed phase synchronization (WPS), with those that directly measure the instantaneous phase synchronization (IPS).

IpaD-loaded N-trimethyl Chitosan Nanoparticles Can Efficiently Protect Guinea Pigs against Shigella flexneri.

Background: Shigella flexneri is a pathogen responsible for shigellosis around the world, especially in developing countries. Many immunogenic antigens have been introduced as candidate vaccines against Shigella, including N-terminal region of IpaD antigen (NIpaD).

Objective: To evaluate the efficiency of O-metylated free trimethyl chitosan nanoparticles (TMC NPs) in the oral delivery of NIpaD.

Evaluation of immune response to recombinant LFD1-PA4 chimeric protein.

Background: Anthrax is a particularly dangerous infectious disease that affects humans and livestock. Efficacious vaccines that can rapidly induce a long-term immune response are required to prevent anthrax infection in humans. Domains 4 and 1 of the protective antigen (PA) and lethal factor (LF), respectively, have very high antigenic properties.

Investigating the impact of autocorrelation on time-varying connectivity.

In recent years, a number of studies have reported on the existence of time-varying functional connectivity (TVC) in resting-state functional magnetic resonance imaging (rs-fMRI) data. The sliding-window technique is currently one of the most commonly used methods to estimate TVC. Although previous studies have shown that autocorrelation can negatively impact estimates of static functional connectivity, its impact on TVC estimates is not well known at this time.
