New weapons explosive exhibits persistent toxicity in plants.

Explosives are widespread, toxic and persistent environmental pollutants. 2,4-Dinitroanisole (DNAN) is being phased in to replace 2,4,6-trinitrotoluene (TNT) in munitions. Here we demonstrate that only low levels of DNAN are detoxified in Arabidopsis, leaving it to remain as a substrate for monodehydroascorbate reductase 6 mediated chronic phytotoxicity.

Integration of Palliative Care into Heart Failure Care: Consensus-Based Recommendations from the Heart Failure Society of America.

Heart failure (HF) is characterized by significant symptoms, compromised quality of life, frequent hospital admissions, and high mortality rates; palliative care (PC) is, therefore, highly relevant for patients with HF and their clinicians. Multiple guidelines and consensus statements recommend the provision of PC alongside HF management. However, few resources exist to guide the integration of PC into HF care, for both primary PC (provided by HF clinicians in the course of HF care) and specialty PC (provided by PC specialists).

COVID-19 vaccine responses are influenced by distinct risk factors in naive and SARS-CoV-2 experienced hemodialysis recipients.

Background: Clinical risk factors of deficient immune responses to COVID-19 mRNA vaccination in SARS-CoV-2 naive hemodialysis recipients (HDR) have already been identified. Clinical factors influencing hybrid immunity induced by SARS-CoV-2 infection and vaccination in HDR have not been reported.

Methods: A comprehensive analysis of antibody (Ab) and T cell responses to two doses of BNT162b2 mRNA vaccination was performed in 103 HDR, including 75 SARS-CoV-2 naive and 28 experienced patients, and in 106 healthy controls (HC) not undergoing HD, including 40 SARS-CoV-2 naive and 66 experienced subjects.

Explaining seasonality increases perceived effectiveness of influenza vaccination: An experimental study.

Background: Doubts regarding vaccine effectiveness may prompt people to decide against a seasonal influenza vaccination. While fact boxes show the effectiveness in terms of cases prevented, people often lack knowledge about important contextual factors, for example, why the vaccine formulation needs to be updated annually, the vaccine mechanism and relevance of the antigen-virus match. Adding such contextual information could improve effectiveness perceptions.

Pink illusions and white shifts.

A rotating stimulus of alternating red and white sectors generates a faint pink fill throughout the image. The trailing cyan after images of the red sectors quickly become the brightest regions in the image, providing an index of the overall illumination that triggers a shift of the white point. Actual white areas then shift in the opposite direction and appear pink.

Covalent adducts formed by the androgen receptor transactivation domain and small molecule drugs remain disordered.

Intrinsically disordered proteins are implicated in many human diseases. Small molecules that target the disordered androgen receptor transactivation domain have entered human trials for the treatment of castration-resistant prostate cancer. These molecules have been shown to react with cysteine residues of the androgen receptor transactivation domain and form covalent adducts under physiological conditions.

Membrane fusion reactions limited by defective SNARE zippering or stiff lipid fatty acyl composition have distinct requirements for Sec17, Sec18, and adenine nucleotide.

Intracellular membrane fusion is catalyzed by SNAREs, Rab GTPases, SM proteins, tethers, Sec18/NSF and Sec17/SNAP. Membrane fusion has been reconstituted with purified vacuolar proteins and lipids to address 3 salient questions: whether ATP hydrolysis by Sec18 affects its promotion of fusion, whether fusion promotion by Sec17 and Sec18 is only seen with mutant SNAREs or can also be seen with wild-type SNAREs, and whether Sec17 and Sec18 only promote fusion when they work together or whether they can each work separately. Fusion is driven by two engines, completion of SNARE zippering (which does not need Sec17/Sec18) and Sec17/Sec18-mediated fusion (needing SNAREs but not the energy from their complete zippering).

Improving antibody-mediated protection against HSV infection by eliminating interactions with the viral Fc receptor gE/gI.

Herpes simplex virus (HSV) encodes surface glycoproteins that are host defense evasion molecules, allowing the virus to escape immune clearance. In addition to their role in neuropathogenesis and cell-cell spread, glycoproteins E and I (gE/gI) form a viral Fc receptor (vFcR) for most subclasses and allotypes of human IgG and promote evasion of humoral immune responses. While monoclonal antibodies (mAbs) protect mice from neonatal HSV (nHSV) infections, the impact of the vFcR on mAb-mediated protection by binding to IgG is unknown.

Transient upregulation of procaspase-3 during oligodendrocyte fate decisions.

Oligodendrocytes are generated throughout life and in neurodegenerative conditions from brain resident oligodendrocyte precursor cells (OPCs). The transition from OPC to oligodendrocyte involves a complex cascade of molecular and morphological states that position the cell to make a fate decision to integrate as a myelinating oligodendrocyte or die through apoptosis. Oligodendrocyte maturation impacts the cell death mechanisms that occur in degenerative conditions, but it is unclear if and how the cell death machinery changes as OPCs transition into oligodendrocytes.

Anhedonia in flux: Understanding the associations of emotion regulation and anxiety with anhedonia dynamics in a sample with major depressive disorder.

Negative rumination and emotion regulation difficulties have been consistently linked with depression. Despite anhedonia-the lack of interest in pleasurable experiences-being a cardinal symptom of depression, emotion regulation of positive emotions, including dampening, are considered far less in the literature. Given that anhedonia may manifest through blunted responses to previously positive or enjoyable experiences, it is vital to understand how different positive emotion regulation strategies impact anhedonia symptom severity and how it can vary or change over time.

The PNUTS phosphatase complex controls transcription pause release.

Gene expression is regulated by controlling distinct steps of the transcriptional cycle, including initiation, pausing, elongation, and termination. Kinases phosphorylate RNA polymerase II (RNA Pol II) and associated factors to control transitions between these steps and to act as central gene regulatory nodes. Similarly, phosphatases that dephosphorylate these components are emerging as important regulators of transcription, although their roles remain less well understood.

Were COVID and the Great Recession well-being reducing?

Using micro-data on six surveys-the Gallup World Poll 2005-2023, the U.S. Behavioral Risk Factor Surveillance System, 1993-2022, Eurobarometer 1991-2022, the UK Covid Social Survey Panel, 2020-2022, the European Social Survey 2002-2020 and the IPSOS Happiness Survey 2018-2023 -we show individuals' reports of subjective wellbeing in Europe declined in the Great Recession of 2008/9 and during the Covid pandemic of 2020-2021 on most measures.

Line-dropped gelatin multi-element calibration standards in LA-ICP-MS: a statistically verifying comparison with cryosectioned homogenized lung and liver as matrix-matched calibration standards and as corresponding reference materials.

Calibrations in LA-ICP-MS are typically very time-consuming and complex, as they need to be matched to the samples being measured and sectioned on a microtome. Alternatively, gelatin can be in droplet form or as a section, which is a more recent development. In this study, we report on investigations where hot multi-element gelatin solutions are placed in a linear fashion on microscopic slides to conduct comparative statistical observations between doped tissue homogenates from the liver and lung.

Engaging children and adolescents in the design and conduct of paediatric research.

The importance of patient engagement in product development and clinical research is widely acknowledged. In pediatrics, parents and guardians are often vocal advocates for their children in the process, but investigators and sponsors rarely directly solicit children's or adolescents' perspectives in clinical research planning or as patient partners during the conduct of research. Here, we provide compelling reasons and recommendations for investigators and sponsors to systematically engage young people in the design, conduct, and review of research, and the premise that input will be incorporated as a routine expectation.

Exploring patient perspectives on shared decision making about bariatric surgery in two healthcare systems.

Objective: To assess patient perspectives on the level of shared decision making (SDM) experienced related to bariatric surgery.

Background: Severe obesity is common and has serious health implications. Yet, few eligible patients pursue bariatric surgery.

Effects of a Gastroscopic Procedure on Salivary Cortisol Release and Fecal Cortisol Metabolites in Young Racehorses.

In this study, gastroscopy was performed twice in 31 two-year-old Thoroughbred racehorses in training. Salivary cortisol (SC) and fecal cortisol metabolite (FCM) concentrations were determined to measure the stress impact. One gastroscopy was performed at the beginning and one six months later at the end of the horses' first training season.

A proteome-wide structural systems approach reveals insights into protein families of all human herpesviruses.

Structure predictions have become invaluable tools, but viral proteins are absent from the EMBL/DeepMind AlphaFold database. Here, we provide proteome-wide structure predictions for all nine human herpesviruses and analyze them in depth with explicit scoring thresholds. By clustering these predictions into structural similarity groups, we identified new families, such as the HCMV UL112-113 cluster, which is conserved in alpha- and betaherpesviruses.

Comparison of Cochet-Bonnet, Dental Floss, and Cotton Wisp With Applications to Corneal Sensation Testing.

Purpose: The measurement of corneal sensation can be useful in the diagnosis of corneal neuropathies. Although the Cochet-Bonnet esthesiometer (CB) is the gold standard, cotton wisp (CW) and dental floss are commonly used in clinical practice.

Methods: We assessed the steady-state force of thick dental floss (tkDF), thin dental floss (tnDF), and CW compared with that of CB.

Heterotopic Ossification of the Adductor Muscles in Bald Eagles ().

Diseases of the musculature can be caused, for example, by alimentary or traumatic issues. In three bald eagles with painful lameness and/or a reduced range of the hip joint, a muscular disease was diagnosed via radiographic examination. The eagles were kept in a falconry and trained as demonstration birds, which were displayed on a gloved hand and flown in falconry education programs.

Detecting Clinically Significant Prostate Cancer in PI-RADS 3 Lesions Using T2w-Derived Radiomics Feature Maps in 3T Prostate MRI.

Prostate Imaging Reporting and Data System version 2.1 (PI-RADS) category 3 lesions are a challenge in the clinical workflow. A better detection of the infrequently occurring clinically significant prostate cancer (csPCa) in PI-RADS 3 lesions is an important objective.

The Management of Non-Muscle-Invasive Bladder Cancer in a Veteran Patient Population: Issues and Recommendations.

The ability of the Veterans Health Administration System to care for veterans with bladder cancer is influenced by the increased complexity of both veterans and the system's capacity to do so, which is determined by personnel and equipment allocation. Herein, we review the guidelines for bladder cancer management in the context of this population and highlight unique veteran characteristics that impact the delivery of bladder cancer care within the Veterans Health Administration System. There are opportunities for standardization and implementation, which can improve the quality of this care, and we summarize the questions for which coordinated research efforts may provide answers.

The July 2024 Trump assassination attempt was followed by lower in-group support for partisan violence and increased group unity.

The attempted assassination of Donald Trump led to widespread concern that the event would escalate political violence between U.S. partisans.
