A novel outer membrane vesicle adjuvant improves vaccine protection against Bordetella pertussis.

Pertussis is a vaccine-preventable respiratory disease caused by the Gram negative coccobacillus Bordetella pertussis. The licensed acellular pertussis (aP) vaccines protect against disease but do not prevent bacterial colonization and transmission. Here, we developed and tested an intranasal vaccine composed of aP antigens combined with T-vant, a novel adjuvant derived from bacterial outer membrane vesicles, that elicits both mucosal and systemic immune responses.

Real-World Outcomes of Immunotherapy for Melanoma Brain Metastases in New Zealand.

Purpose: Melanoma brain metastases (BMs) are associated with poor survival. Combination immune checkpoint inhibitors (ICIs) with anti-PD1 and anti-CTLA-4 are the international standard-of-care treatment. Most landmark clinical trials excluded real-world patients with symptomatic disease, poor performance status (PS), and steroid use.

Testosterone deficiency promotes arterial stiffening independent of sex chromosome complement.

Background: Sex hormones and sex chromosomes play a vital role in cardiovascular disease. Testosterone plays a crucial role in men's health. Lower testosterone level is associated with cardiovascular and cardiometabolic diseases, including inflammation, atherosclerosis, and type 2 diabetes.

Assessment and evaluation of prescribing competences: A systematic review and recommendations.

Aims: Since assessment of prescribing competence is a key promoter of student learning and achievement, we aim to summarize existing national-level approaches, provide a systematic review of current literature, indicate the frequency of various methodologies, and make recommendations to promote and extend existing practice.

Methods: Regulatory body websites were accessed for details of national examinations. PubMed, Embase, the Allied and Complementary Medicine, and CINAHL databases were systematically searched in August 2023 for studies in English from Europe, North America, Australia and New Zealand reporting assessment of prescribing competencies among students/practitioners.

Evidence-based appraisal of the role of SJTs in selection.

A recent opinion article in promoted a new preference-based algorithm to allocate training places for the UK Foundation Programme Office (UKFPO). This replaced the previous process, which ranked candidates based on medical school academic achievement (the educational performance measure; EPM) and the score on a situational judgement test (SJT). Although not without risks, we believe that the new system has positive potential.

Testosterone Deficiency Promotes Arterial Stiffening Independent of Sex Chromosome Complement.

Background: Testosterone plays a vital role in men's health. Lower testosterone level is associated with cardiovascular and cardiometabolic diseases, including inflammation, atherosclerosis, and type 2 diabetes. Testosterone replacement is beneficial or neutral to men's cardiovascular health.

Bordetella spp. block eosinophil recruitment to suppress the generation of early mucosal protection.

Bordetella spp. are respiratory pathogens equipped with immune evasion mechanisms. We previously characterized a Bordetella bronchiseptica mutant (RB50ΔbtrS) that fails to suppress host responses, leading to rapid clearance and long-lasting immunity against reinfection.

Non-mucosal vaccination strategies to enhance mucosal immunity.

The SARS-CoV-2 pandemic has highlighted the need for improved vaccines that can elicit long-lasting mucosal immunity. Although mucosal delivery of vaccines represents a plausible method to enhance mucosal immunity, recent studies utilizing intradermal vaccine delivery or incorporation of unique adjuvants suggest that mucosal immunity may be achieved by vaccination via non-mucosal routes. In this expert insight, we highlight emerging evidence from pre-clinical studies that warrant further mechanistic investigation to improve next-generation vaccines against mucosal pathogens, especially those with pandemic potential.

Complex eco-evolutionary responses of a foundational coastal marsh plant to global change.

Predicting the fate of coastal marshes requires understanding how plants respond to rapid environmental change. Environmental change can elicit shifts in trait variation attributable to phenotypic plasticity and act as selective agents to shift trait means, resulting in rapid evolution. Comparably, less is known about the potential for responses to reflect the evolution of trait plasticity.

Impact of lanthanide ion complexation and temperature on the chemical reactivity of ,,','-tetraoctyl diglycolamide (TODGA) with the dodecane radical cation.

The impact of trivalent lanthanide ion complexation and temperature on the chemical reactivity of ,,','-tetraoctyl diglycolamide (TODGA) with the -dodecane radical cation (RH˙) has been measured by electron pulse radiolysis and evaluated by quantum mechanical calculations. Additionally, Arrhenius parameters were determined for the reaction of the non-complexed TODGA ligand with the RH˙ from 10-40 °C, giving the activation energy ( = 17.43 ± 1.

Establishment of isotype-switched, antigen-specific B cells in multiple mucosal tissues using non-mucosal immunization.

Although most pathogens infect the human body via mucosal surfaces, very few injectable vaccines can specifically target immune cells to these tissues where their effector functions would be most desirable. We have previously shown that certain adjuvants can program vaccine-specific helper T cells to migrate to the gut, even when the vaccine is delivered non-mucosally. It is not known whether this is true for antigen-specific B cell responses.

Assessing opportunities and inequities in undergraduate ecological forecasting education.

Conducting ecological research in a way that addresses complex, real-world problems requires a diverse, interdisciplinary and quantitatively trained ecology and environmental science workforce. This begins with equitably training students in ecology, interdisciplinary science, and quantitative skills at the undergraduate level. Understanding the current undergraduate curriculum landscape in ecology and environmental sciences allows for targeted interventions to improve equitable educational opportunities.

Purpose: To assess whether there are added risks when performing intraocular lens (IOL) exchange in the setting of an open posterior capsule (OPC) when compared with a closed posterior capsule (CPC) IOL exchange.

Setting: Private practice, Los Angeles, California.

Design: Nonrandomized and unmasked retrospective chart review.

Radiolytic Evaluation of 3,4,3-LI(1,2-HOPO) in Aqueous Solutions.

The octadentate hydroxypyridinone ligand 3,4,3-LI(1,2-HOPO) (abbreviated as HOPO) has been identified as a promising candidate for both chelation and -element separation technologies, two applications that require optimal performance in radiation environments. However, the radiation robustness of HOPO is currently unknown. Here, we employ a combination of time-resolved (electron pulse) and steady-state (alpha self-radiolysis) irradiation techniques to elucidate the basic chemistry of HOPO and its -element complexes in aqueous radiation environments.

The Adjuvant Combination of dmLT and Monophosphoryl Lipid A Activates the Canonical, Nonpyroptotic NLRP3 Inflammasome in Dendritic Cells and Significantly Interacts to Expand Antigen-Specific CD4 T Cells.

Adjuvants are often essential additions to vaccines that enhance the activation of innate immune cells, leading to more potent and protective T and B cell responses. Only a few vaccine adjuvants are currently used in approved vaccine formulations in the United States. Combinations of one or more adjuvants have the potential to increase the efficacy of existing and next-generation vaccines.

Rapid plant trait evolution can alter coastal wetland resilience to sea level rise.

Rapid evolution remains a largely unrecognized factor in models that forecast the fate of ecosystems under scenarios of global change. In this work, we quantified the roles of heritable variation in plant traits and of trait evolution in explaining variability in forecasts of the state of coastal wetland ecosystems. A common garden study of genotypes of the dominant sedge , "resurrected" from time-stratified seed banks, revealed that heritable variation and evolution explained key ecosystem attributes such as the allocation and distribution of belowground biomass.

Accounting for variability when resurrecting dormant propagules substantiates their use in eco-evolutionary studies.

There has been a steady rise in the use of dormant propagules to study biotic responses to environmental change over time. This is particularly important for organisms that strongly mediate ecosystem processes, as changes in their traits over time can provide a unique snapshot into the structure and function of ecosystems from decades to millennia in the past. Understanding sources of bias and variation is a challenge in the field of resurrection ecology, including those that arise because often-used measurements like seed germination success are imperfect indicators of propagule viability.

SARS-CoV-2 Antibody Response is Associated with Age in Convalescent Outpatients.

COVID-19 has had an unprecedented global impact on human health. Understanding the antibody memory responses to infection is one tool needed to effectively control the pandemic. Among 173 outpatients who had virologically confirmed SARS-CoV-2 infection, we evaluated serum antibody concentrations, microneutralization activity, and enumerated SARS-CoV-2 specific B cells in convalescent blood specimens.

Electrochemical behaviour of uranium at a tripolyphosphate modified ITO electrode.

UO binds to the surface of a tripolyphosphate modified mesoporous indium tin-doped oxide electrode (ITO|P). Electrochemical studies reveal that ITO|P electrodes catalyze the 2-electron interconversion between UO and U with the P-ligand assisting in the rate-limiting proton-coupled reduction of U(V) to U(IV), based on the kinetic isotope effect (1.8).
