Pangenomes are collections of annotated genome sequences of multiple individuals of a species. The structural variants uncovered by these datasets are a major asset to genetic analysis in crop plants. Here we report a pangenome of barley comprising long-read sequence assemblies of 76 wild and domesticated genomes and short-read sequence data of 1,315 genotypes.

While systematic reviews have compared embolisation to surgery, attempts to compare different embolisation materials have been limited. The objective was to conduct a systematic review assessing the potential benefits of combining coils with sclerosants for varicocele embolisation on fertility, pain, recurrence and complication rates in male patients, as compared to using coils alone.

The focus on maternal outcome measures is more immediately obvious, with comparative and sequential data of blood pressure and urine protein excretion. In non-human primates, the data concerning birthweight requires a greater number of observations and thus will be accumulated over a longer period of time and a greater number of experimental protocols.

Sepsis survivors frequently suffer long-term cognitive impairment, which has been linked to the breakdown of the blood-brain barrier (BBB) during a sepsis-associated "cytokine storm". Because animal models poorly recapitulate sepsis pathophysiology, human models are needed to understand sepsis-associated brain injury and to develop novel therapeutic strategies.

Recently, researchers have documented the need for increased conceptual and measurement clarity, to distinguish internalized weight stigma from body dissatisfaction. Although several systematic reviews have been conducted on portions of the internalized weight stigma literature, no review to date has been conducted examining the entirety of the literature.

Although originally proposed to explain these mental health outcomes in heterosexual women, researchers have extended objectification theory to individuals of various ages, racial identities, and sexual and gender identities. We conducted a systematic literature review of empirical peer-reviewed published research examining the relationship between the constructs of self-objectification, body dissatisfaction, and body shame in adult, youth, and LGBTQ+ samples.

Cuticles also play diverse and specialized functions, including organ separation, depending on plant and tissue. Barley shows a distinctive cuticular wax bloom enriched in β-diketones on leaf sheaths, stem nodes and internodes and inflorescences.

Thus, exploiting understudied genetic resources, that potentially harbour tolerance genes, is vital for sustainable agriculture. Northern European barley germplasm has been relatively understudied despite its key role within the malting industry.

Recently, microphysiological systems (MPS) have emerged as novel in vitro mimetics that facilitate the development of human models of disease. With this advancement, aspects of endothelial physiology that are difficult to assess with other models can be directly probed.

Barley genomic resources are increasing rapidly, with the publication of a barley pangenome as one of the latest developments. Two-row spring barley cultivars are intensely studied as they are the source of high-quality grain for malting and distilling. Here we provide data from a European two-row spring barley population containing 209 different genotypes registered for the UK market between 1830 to 2014.

Preliminary research suggests that the Chinese herbal medicine "Shufeng Jiedu" (SFJD), may improve recovery and therefore reduce antibiotic use in patients with AECOPD. To assess the feasibility of conducting a randomised placebo-controlled clinical trial of SFJD for AECOPD in UK primary care.

Plant breeding and selection have shaped the genetic composition of modern crops over the past decades and centuries and have led to great improvements in agronomic and quality traits. Knowledge of the genetic composition of breeding germplasm is essential to make informed decisions in breeding programs.

The deformability of leukocytes is relevant to a wide array of physiological and pathophysiological behaviors. The goal of this study is to provide a detailed, quantitative characterization of the mechanical properties of T cells and how those properties change with activation. We tested T cells and CD8 cells isolated from peripheral blood samples of healthy donors either immediately (naïve population) or after 7 days of activation .

They have important health-promoting properties in grain, and influence the digestibility of biomass for industrial processing and livestock feed. Both phenolic acids are assumed to be critical to cell wall integrity and ferulic acid, at least, is important for cross-linking cell wall components, but the role of -coumaric acid is unclear.

However, T cell immunotherapies have mostly failed in individuals with solid tumors. Here, with a CRISPR-Cas9 pooled library, we performed an in vivo targeted loss-of-function screen and identified ST3 β-galactoside α-2,3-sialyltransferase 1 (ST3GAL1) as a negative regulator of the cancer-specific migration of CAR T cells.

MPS featuring ultrathin and nanoporous silicon nitride membranes (µSiM) have been utilized in the past to facilitate high magnification phase contrast microscopy recordings of leukocyte trafficking events in a living mimetic of the human vascular microenvironment. Notably, the imaging plane can be set directly at the endothelial interface in a µSiM device, resulting in a high-resolution capture of an endothelial cell (EC) and leukocyte coculture reacting to different stimulatory conditions.

Continuing care (CC) facilities have been impacted by a growing demand for services, insufficient resources for the provision of quality food and nutrition care, and, most recently, the COVID-19 pandemic. This study explored the roles and responsibilities of dietitians working in CC facilities in Nova Scotia (NS) before and after the COVID-19 first wave. Using ethics-approved questionnaires, the estimated 75 dietitians working in CC facilities in NS were surveyed in Fall 2019 and Fall 2020 about their roles and responsibilities.

To breathe, plants interrupt their cuticles with adjustable epidermal pores, called stomata, that regulate gas exchange, and develop other specialised epidermal cells such as defensive hairs.

We demonstrate the approach by exploring CO frequency and distribution in self-fertilised progeny of the inbred barley cultivar Bowman and compare these observations to similar data obtained from a Bowman nearly isogenic line (BW230 containing a mutation in the DNA mismatch repair gene We have previously shown that decreases both plant fertility and recombination by ~50%.
