Among the known leaf rust resistance genes (Lr) genes, Lr32 is a broadly effective gene derived from the diploid species Aegilops tauschii coss. accession RL5497-1 and has been genetically mapped to chromosome arm 3DS. However, Lr32 resistance has not been utilized in current cultivars in part due to lack of modern, predictive DNA markers. The goals of this study were to fine-map the Lr32 region and develop SNP-based kompetitive allele specific PCR (KASP) markers. The genomic analysis was conducted by using doubled haploid and F2-derived mapping populations. For marker development, a 90K wheat chip array, 35K and 820K Axiom R SNPs, A. tauschii pseudomolecules v4.0 and IWGSC ReqSeq v2.1 reference genomes were used. Total 28 KASP and two SSR markers were developed. The Lr32 region was fine mapped between KASP markers Kwh142 and Kwh355 that flanked 34-35 Mb of the diploid and hexaploid reference genomes. Leaf rust resistance mapped as a Mendelian trait that co-segregated with 20 markers, recombination restriction limited the further resolution of the Lr32 region. A total of 10-11 candidate genes associated with disease resistance were identified between the flanking regions on both reference genomes, with the majority belonging to the NLR gene family. The validation analysis selected two KASP markers, Kwh147 and Kwh722, for marker-assisted selection. The presence of Lr32 along with other Lr genes such as Lr67 and Lr34 would increase the resistance in future wheat breeding lines and have a high impact on controlling wheat leaf rust.
Approximately one in four total knee replacement patients develop persistent pain. Identification of those at higher risk could help inform optimal management.

We searched MEDLINE, EMBASE, CINAHL, AMED, SPORTDiscus and PsycINFO for observational studies that explored the association between risk factors and persistent pain (≥3 months) after total knee replacement. We pooled estimates of association for all independent variables reported by > 1 study.

Thirty studies (26,517 patients) reported the association of 151 independent variables with persistent pain after knee replacement. Selleckchem ALKBH5 inhibitor 2 High certainty evidence demonstrated an increased risk of persistent pain with pain catastrophizing (absolute risk increase [ARI] 23%, 95% CI 12 to 35), younger age (ARI for every 10-year decrement from age 80, 4%, 95% CI 2 to 6), and moderate-to-severe acute post-operative pain (ARI 30%, 95% CI 20 to 39). Moderate certainty evidence suggested an association with female sex (ARI 7%, 95% CI 3 to 11) and higher pre-operative pain (ARI 35%, 95% CI 7 to 58). Studies did not adjust for both peri-operative pain severity and pain catastrophizing, which are unlikely to be independent. High to moderate certainty evidence demonstrated no association with pre-operative range of motion, body mass index, bilateral or unilateral knee replacement, and American Society of Anesthesiologists score.

Rigorously conducted observational studies are required to establish the relative importance of higher levels of peri-operative pain and pain catastrophizing with persistent pain after knee replacement surgery.

PROSPERO CRD42018065943.Breast cancer is the most common malignant tumor in women. A previous genome-wide association study reports that rs72755295, a SNP locating at intron of EXO1 (exonuclease 1), is associated with breast cancer. Due to the complete linkage disequilibrium between rs72755295 and rs4149909, a nonsynonymous mutation for EXO1, rs4149909 is supposed to be the causal SNP. Since EXO1 is overexpressed in breast carcinoma samples, we hypothesized that the genetic variations in this locus might confer breast cancer risk by regulating EXO1 expression. To substantiate this, a functional genomics study was performed. The dual luciferase assay indicated that G of rs72755295 presents significantly higher relative enhancer activity than A, thus verifying that this SNP can influence gene expression in breast cell. Through chromosome conformation capture it was disclosed that the enhancer containing rs72755295 can interact with the EXO1 promoter. RNA-seq analysis indicated that EXO1 expression is dependent on the rs72755295 genotype. By chromatin immunoprecipitation, the transcription factor PAX6 (paired box 6) was recognized to bind the region spanning rs72755295. In electrophoretic mobility shift assay, G of rs72755295 displays obviously higher binding affinity with nuclear protein than A. Our results indicated that rs72755295 is a cis-regulatory variation for EXO1 and might confer breast cancer risk besides rs4149909.Biological components (protein, DNA, lipid rafts, etc.) self-sort to form higher-order structures with elegant modulation by endogenous stimuli for maintaining cellular functions in living cells. However, the challenge of producing self-sorted higher-order assemblies of peptides in living systems (cells and tissues) spatiotemporally has yet to be achieved. This work reports the using of a biocompatible strategy to construct self-sorted assemblies of peptides in living cells and tumor-bearing mice. The results show that the designed peptides self-sort to form distinct nanostructures in living cancer cells using an endogenous trigger, as evidenced by confocal laser scanning microscopy and Bio-EM. Wound-healing experiments indicate that the in situ generation of self-sorted nanostructures exhibits a synergistic effect that significantly decreases the migration of cancer cells. In vivo experiments demonstrate that the designed peptides could self-sort in tumor-bearing mice and improve the tumor penetrating ability of the impenetrable component in tumor tissue. We can further program the formation of self-sorted materials through orthogonal triggers by introducing an exogenous trigger (light) and an endogenous trigger independently. Thus, this work provides a strategy to control multiple self-assembling processes in the context of the living system and provides a general strategy to construct self-sorted structures for the emergent properties of materials science.The cancerous inhibitor of protein phosphatase 2A (CIP2A) is an oncoprotein found overexpressed in many types of cancer. CIP2A has been shown to stabilize oncoproteins such as cMYC by shielding them from PP2A-mediated dephosphorylation. Here we report that the penultimate residue Ser904 in the C-terminus of CIP2A can be phosphorylated to create a binding site for the regulatory protein 14-3-3. We demonstrate that 14-3-3 is a new interaction partner of CIP2A. The 14-3-3/CIP2A C-terminal interaction complex can be targeted by the protein-protein interaction (PPI) stabilizer fusicoccin-A (FC-A), resulting in enhanced levels of phosphorylated Ser904. FC-A treatment of TNBC cells leads to the increased association of CIP2A with 14-3-3. We show that the composite interface between 14 and 3-3 and CIP2A's C-terminus can be targeted by the PPI stabilizer FC-A, providing a new interface that could potentially be exploited to modulate CIP2A's activity.
It is of scientific interest to identify DNA methylation CpG sites that might mediate the effect of an environmental exposure on a survival outcome in high-dimensional mediation analysis. However, there is a lack of powerful statistical methods that can provide a guarantee of false discovery rate (FDR) control in finite-sample settings.

In this article, we propose a novel method called CoxMKF, which applies aggregation of multiple knockoffs to a Cox proportional hazards model for a survival outcome with high-dimensional mediators. The proposed CoxMKF can achieve FDR control even in finite-sample settings, which is particularly advantageous when the sample size is not large. Moreover, our proposed CoxMKF can overcome the randomness of the unstable model-X knockoffs. Our simulation results show that CoxMKF controls FDR well in finite samples. We further apply CoxMKF to a lung cancer dataset from The Cancer Genome Atlas (TCGA) project with 754 subjects and 365306 DNA methylation CpG sites, and identify four DNA methylation CpG sites that might mediate the effect of smoking on the overall survival among lung cancer patients.

To compare the clinical effectiveness of sodium polynucleotide, classic hyaluronic acid, and crosslinked hyaluronic acid for the management of painful knee osteoarthritis.

Randomized, double-blind, parallel-group clinical trial.

Multicenter study.

Patients with chronic painful knee osteoarthritis.

Ninety patients were selected and randomized into polynucleotide, classic hyaluronic acid, and crosslinked hyaluronic acid groups (30 per group). Intra-articular injections of the viscosupplement for each group were administered to the patients three times at one-week intervals. The primary outcome was differences in changes of weight-bearing pain scores at 16 weeks between the groups. The secondary outcomes were changes in the intensity of knee pain during weight-bearing, walking, and rest, and functional disability, quality of life, and adverse events during the 16-week follow-up period.

At 16 weeks, the polynucleotide group showed a higher reduction in pain score using a Visual Analog Scale score (0-100) than the classic hyaluronic acid (-17.6 [95% CI = -35.1 to -0.1]; P = 0.048) and crosslinked hyaluronic acid (-22.4 [95% CI = -41.5 to -3.3]; P = 0.016) groups. The polynucleotide and crosslinked hyaluronic acid groups showed an early-onset reduction in knee pain during weight-bearing, walking, and rest. All three groups showed reductions in functional disability and improved quality of life at 16 weeks without inter-group differences. No severe adverse events were reported throughout the study period.

Polynucleotide significantly relieves pain more and relieves pain faster in patients with knee osteoarthritis than classic and crosslinked hyaluronic acid, with improved health-related quality of life.

This is a presentation of a 52-year-old female worker exposed to black pepper dust for 10 years suffering from allergic rhinitis and chronic rhinosinusitis. She complained of nasal obstruction, rhinorrhoea, and a weakened sense of smell. Clinical examination showed the bilateral presence of polypoid lesions arising from the middle turbinate. After surgery, histopathological examination confirmed the diagnosis of inflammatory nasal polyps. Duration of exposure to black pepper and serum concentration of specific immunoglobulin E antibodies indicating work-related exposure would support a causal link between exposure to these factors and the development of chronic inflammation in the nasal mucosa. Inflammatory nasal polyps may be noted in the nasal cavity in workers exposed to black pepper dust. The absence of exposure to black pepper resulted in no detectable circulating antibodies one year after the change of workplace.
