Helicobacter pylori infection is strongly associated with gastritis, gastroduodenal ulcer disease and gastric carcinoma. The virulence of H. pylori strains increases with the presence of the pathogenicity island PAI, which encodes a Type 4 Secretion System and the oncoprotein CagA. Two major CagA types can be distinguished by differences in the repetitive EPIYA region in the C-terminal sequence; the more virulent East Asian CagA type with EPIYA-A, -B, and -D motifs and the Western CagA type with EPIYA-A, -B, and C motifs, the virulence of which is associated with the multitude of EPIYA-C motifs. In this study, the cagA gene was characterized in H. pylori strains isolated from Mongolians suffering from gastritis (80%) or ulcer (20%). The EPIYA region of 53 isolates was determined by PCR-amplification of overlapping cagA regions and subsequent Sanger sequencing. Only one H. pylori isolate carried the East Asian type (ABD) and 52 isolates the Western type of CagA, thereof 30 the EPIYA type ABC, 19 the ABCC type and one each of type ABCCCC, AAABC and AAAAB. An amino acid exchange from EPIYA-B to EPIYT-B was predominantly found in CagA proteins in strains with less then 2 EPIYA-C copies (n = 25/32; p = 0.015) including the two EPIYA-A enriched CagA proteins, which have not been described to date. Due to the amino acid triplet preceding the EPIYA motif and strength of predicted phosphorylation, the multiple EPIYA-A motifs A2, A3 and A4 were shown to cluster with EPIYA-B and EPIYT-B with the unique feature of amino acid E in position - 4 to Y of EPIYA. It has been described that tyrosine-phosphorylated EPIYA-A and -B motifs counteract the EPIYA-C-driven signaling towards host cell transformation and malignancy. Thus, Mongolian H. pylori strains carrying CagA proteins not only with a few EPIYA-C segments but also with multiplied EPIYA-A segments are probably less virulent; a thesis that needs further investigation at the protein level.In order to meet the demand of the burgeoning human population as well as to adapt crops to the enhanced abiotic and biotic stress caused by the global climatic change, breeders focus on identifying valuable genes to improve both crop stress tolerance and crop quality. Recently, with the development of next-generation sequencing methods, millions of high quality single-nucleotide polymorphisms (SNPs) have been made available and genome-wide association studies (GWAS) are widely used in crop improvement studies to identify the associations between genetic variants of genomes and relevant crop agronomic traits. Here, we review classic cases of use of GWAS to identify genetic variants associated with valuable traits such as geographic adaptation, crop quality and metabolites. We discuss the power of stress GWAS to identify further associations including those with genes that are not, or only lowly, expressed during optimal growth conditions. Finally, we emphasize recent demonstrations of the efficiency and accuracy of time-resolved dynamic stress GWAS and GWAS based on genomic gene expression and structural variations, which can be applied to resolve more comprehensively the genetic regulation mechanisms of complex traits.Polyglutamine (polyQ) model peptides are ideally suited to analyze the involvement of glutamines in the disease-related aggregation onset. Here we use a template-assisted design of polyQ-rich hairpin peptides (Trpzip-Qn) to monitor structural stability with fluorescence spectroscopy. The hairpin model imitates the monomeric motif of a polyQ fibril and is stabilized by hydrophobic interactions of two cross-strand pairs of tryptophans (Trps) which are used as fluorophores to report on structural changes. The Trps also frame the polyQ repeats located on each hairpin strand with a different number of glutamines (Qn). Single-stranded sequences mimic the unfolded state and were used as references to differentiate the intrinsic fluorescence signal from the spectral effect caused by structural changes. Temperature-induced hairpin unfolding was monitored by the spectral shift of the Trp fluorescence signal and transition temperatures were determined. The magnitude of the spectral shift indicates the degree of structural disorder. We observed that a longer polyQ repeat is more disordered and weakens the cross-strand Trp-Trp interactions resulting in a decrease of the spectral shift. Aggregation to a fibrillar and more ordered structure shows an increase of the spectral shift. In addition, a band at 280 nm occurs in the spectrum which clearly correlates with the turbidity of the sample and is attributed to scattering of larger aggregated structures. Our study reveals that the number of glutamines, pH and temperature affect structural stability and aggregation of polyQ repeats.
Cryotherapy is a frequently used therapy in the acute treatment of sports injuries, although it has possible negative effects on dynamic postural stabilization.

What is the effect of cryotherapy on the postural stabilization assessed by imposed platform perturbations?

Twenty-four healthy participants (15 male, 9 female) performed 2 test sessions (before and after cryotherapy) consisting of 4 trials each. Each trial included 30s single leg stance (SLS) on both legs and 4 testing blocks (2 for each leg) of 30s for the dynamic testing. A single testing block comprised 4 perturbations. After the first session, cryotherapy was applied to the right leg by placing it in ice water at a temperature between 10°C and 12° for 20min.

We assessed the Center of Pressure speed (CoPs) and the mean force variation for both static and dynamic tests. Additionally, the Time To Stability (TTS) was calculated for the perturbations.

In the static trials there was an interaction between leg and session present for the mean force variation (p=0.01) with a large η
of 0.24, which shows higher variation of vertical force after application of the cryotherapy on the right leg. During the dynamic trials we found an interaction between leg and session for the TTS suggesting increase of the TTS due to the cryotherapy (p=0.04), with a large η
of 0.17. No interaction effect was present for the CoPs in the mediolateral and anteroposterior direction (p=0.62 and p=0.12, respectively).

Cryotherapy applied to the lower extremity results in a worse postural stabilization when assessed by platform perturbations. This might be the result of an altered balance strategy, due to impaired proprioception from the affected body part. More research is needed to examine the duration of this effect.

Level 3, associative study.
Level 3, associative study.The inhibitory receptor CD200R1 and its paired activating receptor CD200R1L are involved in the regulation of myeloid cell immune responses. The aim of this study was to analyze their distribution, regulation by cytokines, and function in porcine monocyte subsets. Ruxolitinib manufacturer We had previously observed that CD200R1 and CD200R1L genes can generate different protein isoforms through alternative mRNA splicing, therefore in this study, we explored the diversity of transcripts in monocyte subsets, and described several new splicing variants of both CD200R1 and CD200R1L, some of which could be expressed on the porcine monocyte surface. A substantial proportion of CD163-SLAII+ and most CD163+SLAII+ monocytes expressed CD200R1 and CD200R1L receptors, while CD163-SLAII- monocytes did not. CD200R1 and CD200R1L expression was down-regulated in monocytes polarized by IFN-ɣ, a cytokine that induces classical activation of macrophages, while IL-10 which gives rise to regulatory macrophages, increased the expression of CD200R1. Finally, treatment of monocyte subsets with a monoclonal antibody specific for the inhibitory CD200R1 receptor and its splicing variants enhanced TNFα and IL-8 production, induced by TLR4 or TLR7 stimulation, suggesting a modulatory role for these receptors on porcine monocyte functions.
Research has consistently shown a relationship between adverse childhood experiences (ACEs) and poor mental health outcomes, and recent research shows that sexual and gender minority (SGM) individuals are at increased risk for ACEs. Moreover, SGM individuals may experience unique ACEs. Increased risk for exposure to traditional and SGM-specific ACEs are related to heterosexism.

The purpose of this paper is two-fold. First, establish the need for an SGM specific ACEs framework that accounts for exposure to heterosexism. Second, assess the psychometric properties of the SGM-ACEs scale.

Data were collected using a multifaceted sampling strategy. In total, 1725 self-identified SGM Texans completed an online survey about ACEs, SGM-ACEs, mental health diagnoses, and demographic characteristics.

The most commonly reported SGM-ACEs were seeing or hearing of other SGM being physical harmed (71.2%), being bullied in school for being SGM (67.9%), and hearing religious leaders say homophobic, biphobic, or transphobic things (60.8%). The EFA showed that 7-items loaded onto a single factor and the CFA indicated a good model fit, with items showing a significant factor loading higher than 0.60. SGM-ACE showed adequate to good psychometric properties and predicted depression (AOR=1.49, CI=1.20, 1.86), anxiety (AOR=1.61, CI=1.25, 2.00), and PTSD (AOR=1.97, CI=1.47, 2.66), when controlling for ACEs and demographic factors.

The 7-item SGM-ACEs measure is a psychometrically sound and unidimensional measure that can be quickly used to assess common adverse childhood experiences related to heterosexism.

Adsorption is considered an effective technique for PFOA removal and more efficient PFOA sorbents are still of interest. This study developed a dual grafted fluorinated hydrocarbon amine weak anion exchange (WAX) polymeric resin (Sepra-WAX-KelF-PEI) for PFOA removal from water. This polymer was synthesized by a two-step amine grafting reaction procedure involving first the reaction of the Sepra-WAX hydrocarbon polymer with poly(vinylidinefluoride-chlorotrifluoroethylene) (Kel-F 800) and then a second reaction with polyethyleneimine (PEI). Characterization of the synthesized polymers was performed using scanning electron microscopy and elemental analysis (F and Cl) by energy dispersive X-ray spectroscopy. The PFOA adsorption performance evaluations were conducted by packed column flow analyses with on-line detection. The results show the breakthrough of the Sepra-WAX-KelF-PEI synthesized with optimum stoichiometry was two times better than the starting anion exchange polymer Sepra-WAX, and six times better than powdered activated carbon, when using the same column size. The adsorption mechanisms of this novel adsorbent including hydrophobic interaction and electrostatic interaction were also clarified in this study. The adsorption kinetic parameters of the two optimum synthesized sorbents were determined using the Thomas model, the Yoon-Nelson model, and batch isotherm studies, and compared with those found with activated carbon and the starting WAX resin. Good agreement of the batch isotherm and column studies with respect to adsorption capacities trends between all three polymers (Sepra-WAX, Sepra-WAX-KelF, and Sepra-WAX-KelF-PEI) were noted.
