Background: The increasing size of the ageing English prison population means that non-communicable diseases such as cancer are being more commonly diagnosed in this setting. Little research has so far considered the incidence of cancer in the English prison population, the treatment patients receive when they are diagnosed in a prison setting, their care costs and outcomes or their experiences of care compared with those of people diagnosed in the general population. This is the first mixed-methods study that has been designed to investigate these issues in order to inform recommendations for cancer practice, policy and research in English prisons.

Mutants with simultaneous germline mutations were obtained in all three F5H genes and all three FAD2 genes (one to eleven mutated alleles) in order to improve the feed value of the seed meal and the fatty acid composition of the seed oil. In mutants with multiple mutated F5H alleles, sinapine in seed meal was reduced by up to 100%, accompanied by a sharp reduction in the S-monolignol content of lignin without causing lodging or stem break. A lower S-lignin monomer content in stems can contribute to improved stem degradability allowing new uses of stems.

Thrips tabaci is the main thrips species affecting onion and related species. It is a cryptic species complex comprising three phylogenetic groups characterized by different reproductive modes (thelytoky or arrhenotoky) and host plant specialization. Thrips tabaci populations vary widely in genetic diversity, raising questions about the factor(s) that drive this diversity.

Memory reconsolidation interventions offer an exciting alternative to exposure treatment because they may target fear memories directly, thereby preventing relapse. A previous reconsolidation intervention for spider fear abruptly reduced avoidance behaviour, whereas changes in self-reported fear followed later. In this pre-registered placebo-controlled study, we first aimed to conceptually replicate these effects in spider phobia.

Background: The allo-octoploid Fragaria x ananassa follows disomic inheritance, yet the high sequence similarity among its subgenomes can lead to misalignment of short sequencing reads (150 bp). This misalignment results in an increased number of erroneous variants during variant calling. To accurately associate traits with the appropriate subgenome, it is essential to filter out these erroneous variants.

Objective: Adhesions between the uterus, bladder and anterior abdominal wall are associated with clinical sequelae, including chronic pelvic pain and dyspareunia, and can also yield complications during surgery. The transvaginal sonographic (TVS) sliding bladder sign is a minimally invasive diagnostic tool to evaluate the presence of vesicouterine adhesions. This study aimed to determine the predictive value and intra- and interobserver variation of the TVS sliding bladder sign in the assessment of vesicouterine adhesions.

Background And Objectives: Routine coagulation screens at birth are still standard in some European neonatal intensive care units (NICUs), although interpretation of these results is complex in preterm infants. It is unclear to what extent local coagulation assay results agree with published reference ranges when using different analysers and reagents. We aimed to assess coagulation assay results on day 1 of life in very preterm infants admitted to the NICU.

Autistic people often experience difficulties with healthcare, and are more likely than neurotypical people to have unmet healthcare needs. They may also be more likely to find menstruation and menopause more difficult than neurotypical women. Healthcare professionals (HCPs) often have insufficient training and support to work with autistic adults, and they often lack the skills or confidence to discuss reproductive and sexual health (RSH) with patients.

Article Synopsis
  • * Researchers used a genetic linkage map created from a cross of resistant African horned melon (Cucumis metuliferus) to identify a QTL (QTL3.1) responsible for some resistance to the nematode.
  • * The study identified two candidate genes (EVM0025394 and EVM0006042) that may play a role in resistance, paving the way for more detailed research and potential development of resistant cucumber cultivars.

  • - Digital breast tomosynthesis (DBT), when used with a synthetic 2D mammogram (S2D), exposes women to higher radiation but may enhance cancer detection compared to full-field digital mammography (FFDM) alone.
  • - A review of 17 studies, including 13 for meta-analysis, found that DBT plus S2D provided a higher cancer detection rate compared to FFDM alone, while also showing similar accuracy to DBT with FFDM.
  • - The findings suggest that integrating S2D with DBT in breast cancer screening is effective and maintains the safety and performance of the imaging process.

Article Synopsis
  • A balanced immune system is crucial for defending against infections and preventing autoimmune diseases; an ineffective response allows infections to thrive, while uncontrolled activation can cause inflammatory disorders.
  • Researchers screened 1200 small molecules to find drugs that can modify immune cell functions, focusing on T cells, B cells, and polymorphonuclear leukocytes (PMNs) for chronic inflammatory diseases.
  • They identified candidate drugs like pyrvinium pamoate, which effectively suppressed B cell activation and slowed down an autoimmune condition, and studied mechanisms in gene-deleted mice to further understand how these actions occur, paving the way for potential drug repurposing to manage immune responses.

Background And Objectives: Ecological momentary assessment is a popular method for monitoring symptoms in real-time. Especially for fleeting experiences, such as intrusions, real-time assessments may be more accurate than retrospective estimates. However, there are concerns regarding reactivity effects associated with real-time assessments and, conversely, the reliance on bias-prone retrospective assessments in clinical science and practice.

We genotyped a population of 618 diploid potato clones derived from six independent potato-breeding programmes from NW-Europe. The diploids were phenotyped for 23 traits, using standardized protocols and common check varieties, enabling us to derive whole population estimators for most traits. We subsequently performed a genome-wide association study (GWAS) to identify quantitative trait loci (QTL) for all traits with SNPs and short-read haplotypes derived from read-backed phasing.

Recent advances in diploid F hybrid potato breeding rely on the production of inbred lines using the () gene. As a result of this method, female parent lines are self-fertile and require emasculation before hybrid seed production. The resulting F hybrids are self-fertile as well and produce many undesirable berries in the field.
