Using two polygenic scores (PGS) for educational attainment in a biomedical study of all those born in a single week in Great Britain in 1958 we show that the genetic predisposition for educational attainment is associated with labour market participation and wages over the life-course for men and women. Those with a higher PGS spend more time in employment and full-time employment and, when in employment, earn higher hourly wages. The employment associations are four times larger for women than for men.

Background: There has been a resurgence of research into the potential therapeutic benefits of psychedelics for neuropsychiatric disorders. Classic psychedelics, such as psilocybin, exert complex effects on higher cognitive functions such as perception and awareness, but their impact on motor function remains unexplored. Moreover, there is a theoretical rationale for using psychedelics to promote motor retraining in certain neuropsychiatric conditions associated with motor dysfunction.

Background: Although the current combination of surgery, radiation, and chemotherapy is used in the breast-cancer setting, the administration of the anticancer drugs doxorubicin and trastuzumab is associated with an increased risk of developing heart failure. The aim of this study is to determine whether dietary flaxseed is comparable and/or synergistic with the angiotensin-converting enzyme inhibitor perindopril in the treatment of doxorubicin- and trastuzumab-mediated cardiotoxicity.

Methods: In a chronic murine model (n = 110), doxorubicin and trastuzumab (8 mg/kg and 3 mg/kg, respectively) were administered weekly for 3 weeks.

Despite the first-line recommendation of fosfomycin for uncomplicated urinary tract infections (UTIs), there are pressing barriers for optimizing its use for the treatment of non- Enterobacterales UTI. There are no approved breakpoints for oral use against other Enterobacterales, and the recommended agar dilution (AD) reference method for minimal inhibitory concentration (MIC) determination is largely impractical. Using 160 clinical isolates, we sought to understand rates of skipped wells and MIC imprecision in broth microdilution (BMD) and how that compares to rates of error using AD.

During the last decade brain organoids have emerged as an attractive model system, allowing stem cells to be differentiated into complex 3D models, recapitulating many aspects of human brain development. Whilst many studies have analysed anatomical and cytoarchitectural characteristics of organoids, their functional characterisation has been limited, and highly variable between studies. Standardised, consistent methods for recording functional activity are critical to providing a functional understanding of neuronal networks at the synaptic and network level that can yield useful information about functional network phenotypes in disease and healthy states.

Background: The colonization of land and the diversification of terrestrial plants is intimately linked to the evolutionary history of their symbiotic fungal partners. Extant representatives of these fungal lineages include mutualistic plant symbionts, the arbuscular mycorrhizal (AM) fungi in Glomeromycota and fine root endophytes in Endogonales (Mucoromycota), as well as fungi with saprotrophic, pathogenic and endophytic lifestyles. These fungal groups separate into three monophyletic lineages but their evolutionary relationships remain enigmatic confounding ancestral reconstructions.

As the field of plant synthetic biology continues to grow, Agrobacterium-mediated transient expression has become an essential method to rapidly test pathway candidate genes in a combinatorial fashion. This is especially important when elucidating and engineering more complex pathways to produce commercially relevant chemicals like many terpenoids, a widely diverse class of natural products of often industrial relevance. Agrobacterium-mediated transient expression has facilitated multiplex expression of recombinant and modified enzymes, including synthetic biology approaches to compartmentalize the biosynthesis of terpenoids subcellularly.

Article Synopsis
  • The Clinical and Laboratory Standards Institute (CLSI) updated its guidelines, suggesting that cefazolin is a better predictor for susceptibility to cephalosporins in uncomplicated urinary tract infections (uUTIs) compared to cephalothin.
  • A new cefazolin surrogacy breakpoint has been established to help predict susceptibility for seven oral cephalosporins in the context of uUTIs.
  • The implementation of this cefazolin breakpoint presents challenges for clinical labs, requiring a review of historical data, pharmacokinetics, and clinical outcomes related to its use.

Drugs that modulate the GABA receptor are widely used in clinical practice for both the long-term management of epilepsy and emergency seizure control. In addition to older medications that have well-defined roles for the treatment of epilepsy, recent discoveries into the structure and function of the GABA receptor have led to the development of newer compounds designed to maximise therapeutic benefit whilst minimising adverse effects, and whose position within the epilepsy pharmacologic armamentarium is still emerging. Drugs that modulate the GABA receptor will remain a cornerstone of epilepsy management for the foreseeable future and, in this article, we provide an overview of the mechanisms and clinical efficacy of both established and emerging pharmacotherapies.

Interventions aimed at teaching composite dressing skills assess individuals' current abilities and improve their performance at more independent and fluent levels. The current case study aims to report on the improvements observed when specific component motor skills are targeted for improved performance using frequency building techniques. We extend previous research by including the measure of escape-maintained behaviors during task completion.

Most studies examining the impact of bullying on wellbeing in adulthood rely on retrospective measures of bullying and concentrate primarily on psychological outcomes. Instead, we examine the effects of bullying at ages 7 and 11, collected prospectively by the child's mother, on subjective wellbeing, labour market prospects, and physical wellbeing over the life-course. We exploit 12 sweeps of interview data through to age 62 for a cohort born in a single week in Britain in 1958.

The model moss species Physcomitrium patens has long been used for studying divergence of land plants spanning from bryophytes to angiosperms. In addition to its phylogenetic relationships, the limited number of differential tissues, and comparable morphology to the earliest embryophytes provide a system to represent basic plant architecture. Based on plant-fungal interactions today, it is hypothesized these kingdoms have a long-standing relationship, predating plant terrestrialization.

Purpose: Delays in outpatient specialist neurologist care for people with epilepsy are common despite recommendations for prompt access. There is evidence to suggest that there are interventions that can minimise waitlists and waiting time. However, little is known about whether such interventions can result in sustained improvements in waiting.

Objectives: Widespread use of telemedicine for contraceptive care, including long-acting reversible contraception (LARC), was adopted in the United States in response to the COVID-19 pandemic. Given the rapid implementation of these services, little is known about the use of telemedicine for adolescent and young adult (AYA) contraceptive care. This study examined the routine use of telemedicine for LARC post-insertion care by comparing visit attendance between AYAs receiving LARC before and after the COVID-19 pandemic onset.

Although yet to be clearly identified as a clinical condition, there is immense concern at the health and wellbeing consequences of long COVID. Using data collected from nearly half a million Americans in the period June 2022-December 2022 in the US Census Bureau's Household Pulse Survey (HPS), we find 14 percent reported suffering long COVID at some point, half of whom reported it at the time of the survey. Its incidence varies markedly across the United States-from 11 percent in Hawaii to 18 percent in West Virginia-and is higher for women than men, among Whites compared with Blacks and Asians, and declines with rising education and income.

A giant basal cell carcinoma (GBCC) is a rare variant of basal cell carcinoma (BCC) that is larger (>5 cm) and more aggressive. While BCC is usually surgically excised as a small, local tumor, cases of GBCC represent a considerable portion of BCC malignancies and mortality. The growth of GBCC is hypothesized to be multifactorial, and due to the successful treatment of BCC, available data is limited.

Article Synopsis
  • Early-diverging Mucoromycota fungi, including mycorrhizal types and Mortierellaceae, contain Mollicutes-related endobacteria (MRE), which may have been inherited from a common ancestor or acquired after species separation.
  • Researchers generated and analyzed complete genomes from MRE found in two genera, Linnemannia and Benniella, revealing them to be the smallest known fungal endosymbionts with genetic adaptations indicating a close relationship with their fungal hosts.
  • The study suggests that MRE from Linnemannia and Benniella likely evolved independently after their fungal hosts diverged, contributing new insights into the evolution of these bacterial endosymbionts and their minimal genomes.

Intimate associations between fungi and intracellular bacterial endosymbionts are becoming increasingly well understood. Phylogenetic analyses demonstrate that bacterial endosymbionts of Mucoromycota fungi are related either to free-living Burkholderia or Mollicutes species. The so-called Burkholderia-related endosymbionts or BRE comprise Mycoavidus, Mycetohabitans and Candidatus Glomeribacter gigasporarum.
