We aimed to examine the effect of β2-agonists on anaerobic performance in healthy non-asthmatic subjects.

Systematic review and meta-analysis.

We searched four databases (PubMed, Embase, SPORTDiscus and Web of Science) for randomised controlled trials, published until December 2019, examining the effect of β2-agonists on maximal physical performance lasting 1 min or shorter. Data are presented as standardised difference in mean (SDM) with 95% confidence intervals (95% CI).

34 studies were included in the present meta-analysis. The studies include 44 different randomised and placebo-controlled comparisons with β2-agonists comprising 323 participants in crossover trials, and 149 participants in parallel trials. In the overall analyses, β2-agonists improved anaerobic performance by 5% (SDM 0.29, 95% CI 0.16 to 0.42), but the effect was related to dose and administration route. In a stratified analysis, the SDM was 0.14 (95% CI 0.00 to 0.28) for approved β2-agonists and 0.46 (95% CI 0.24 to 0.68) for prohibited β2-agonists, respectively. Furthermore, SDM was 0.16 (95% CI 0.02 to 0.30) for inhaled administration and 0.51 (95% CI 0.25 to 0.77) for oral administration, respectively, and 0.20 (95% CI 0.07 to 0.33) for acute treatment and 0.50 (95% CI 0.20 to 0.80) for treatment for multiple weeks. Analyses stratified for the type of performance showed that strength (0.35, 95% CI 0.15 to 0.55) and sprint (0.17, 95% CI 0.06 to 0.29) performance were improved by β2-agonists.

Our study shows that non-asthmatic subjects can improve sprint and strength performance by using β2-agonists. It is uncertain, however, whether World Anti-Doping Agency (WADA)-approved doses of β2-agonists improve performance. KG-501 purchase Our results support that the use of β2-agonists should be controlled and restricted to athletes with documented asthma.

However, the extent to which the network predictions are biologically relevant is often unclear. Recently a GENIE3 network which predicted targets of wheat transcription factors was produced. Here we used an independent RNA-Seq dataset to test the predictions of the wheat GENIE3 network for the senescence-regulating transcription factor NAM-A1 (TraesCS6A02G108300). We re-analyzed the RNA-Seq data against the RefSeqv1.0 genome and identified a set of differentially expressed genes (DEGs) between the wild-type and nam-a1 mutant which recapitulated the known role of NAM-A1 in senescence and nutrient remobilisation. We found that the GENIE3-predicted target genes of NAM-A1 overlap significantly with the DEGs, more than would be expected by chance. Based on high levels of overlap between GENIE3-predicted target genes and the DEGs, we identified candidate senescence regulators. We then explored genome-wide trends in the network related to polyploidy and found that only homeologous transcription factors are likely to share predicted targets in common. However, homeologs which vary in expression levels across tissues are less likely to share predicted targets than those that do not, suggesting that they may be more likely to act in distinct pathways. This work demonstrates that the wheat GENIE3 network can provide biologically-relevant predictions of transcription factor targets, which can be used for candidate gene prediction and for global analyses of transcription factor function. The GENIE3 network has now been integrated into the KnetMiner web application, facilitating its use in future studies.Macadamia integrifolia is a representative of the large basal eudicot family Proteaceae and the main progenitor species of the Australian native nut crop macadamia. Since its commercialisation in Hawaii fewer than 100 years ago, global production has expanded rapidly. However, genomic resources are limited in comparison to other horticultural crops. The first draft assembly of M. integrifolia had good coverage of the functional gene space but its high fragmentation has restricted its use in comparative genomics and association studies. Here we have generated an improved assembly of cultivar HAES 741 (4,094 scaffolds, 745 Mb, N50 413 kb) using a combination of Illumina paired and PacBio long read sequences. Scaffolds were anchored to 14 pseudo-chromosomes using seven genetic linkage maps. This assembly has improved contiguity and coverage, with >120 Gb of additional sequence. Following annotation, 34,274 protein-coding genes were predicted, representing 90% of the expected gene content. Our results indicate that the macadamia genome is repetitive and heterozygous. The total repeat content was 55% and genome-wide heterozygosity, estimated by read mapping, was 0.98% or an average of one SNP per 102 bp. This is the first chromosome-scale genome assembly for macadamia and the Proteaceae. It is expected to be a valuable resource for breeding, gene discovery, conservation and evolutionary genomics.This enquiry examines problems which haunt the 'heart' and its donation. It begins by examining the heart's enduring significance for culturally mediated self-understanding, its vulnerability to misunderstanding and abuse and its relevance to challenging the determination of death by neurological criteria. Despite turns to brain-centred self-conceptions, the heart remains haunted by the hybrid experiences of identity accompanying organ transplant, the relational significance attached to dead hearts witnessed in the Alder Hey scandal and claims that heart transplants commonly constitute the legitimate killing of a person. To explore these phenomena, traditions are retrieved in which the heart-as-organ was construed in terms of a person's core identity. Influential Abrahamic beliefs about 'the heart' are considered in order to explore explanations for why the heart remains culturally pre-eminent, to make intelligible our haunted hearts and to examine possible violations of solidarity in organ donation practice.ts for the sake of retrieving their organs.
Peripheral nerve block (PNB) is an effective pain management option after shoulder arthroplasty with increasing popularity over the past decade. Large-scale US data in shoulder arthroplasties are lacking, especially regarding impacts on opioid utilization. This population-based study aimed to evaluate PNB utilization patterns and their effect on outcomes after inpatient and outpatient shoulder arthroplasty.

This retrospective cohort study used data from the nationwide Premier Healthcare claims database (2006-2016). This study includes n=94 787 and n=3293 inpatient and outpatient (total, reverse and partial) shoulder arthroplasty procedures. Multivariable mixed-effects models estimated associations between PNB use and opioid utilization in oral morphine equivalents and cost of hospitalization/stay. For the inpatient group, additional outcome measures were length of stay (LOS), admission to a skilled nurse facility, 30-day readmission, combined complications and naloxone use (as a proxy for opioid-related complications).
