Quantification of fungal biomass in mycelium composites made from diverse biogenic side streams.

Mycelium composite materials are comprised of renewable organic substrates interconnected by fungal mycelium, allowing full biodegradability after use. Due to their promising material properties, adaptability, and sustainable nature, these biomaterials are investigated intensively. However, one crucial aspect that has hardly been covered so far is the proportion of fungal biomass in the composites, which would be necessary to assess its contribution to the material characteristics.

The decision for or against mycoparasitic attack by Trichoderma spp. is taken already at a distance in a prey-specific manner and benefits plant-beneficial interactions.

Background: The application of plant-beneficial microorganisms as bio-fertilizer and biocontrol agents has gained traction in recent years, as both agriculture and forestry are facing the challenges of poor soils and climate change. Trichoderma spp. are gaining popularity in agriculture and forestry due to their multifaceted roles in promoting plant growth through e.

Modulation of Electrostatic Potential in 2D Crystal Engineered by an Array of Alternating Polar Molecules.

The moiré potential in rotationally misfit two-dimensional (2D) heterostructures has been used to build artificial exciton and electron lattices, which have become platforms for realizing exotic electronic phases. Here, we demonstrate a different approach to create a superlattice potential in 2D crystals by using the near field of an array of polar molecules. A bilayer of titanyl phthalocyanine (TiOPc), consisting of alternating out-of-plane dipoles, is deposited on monolayer MoS.

Dynamic stereomutation of vinylcyclopropanes with metalloradicals.

The ever increasing demands for greater sustainability and lower energy usage in chemical processes call for fundamentally new approaches and reactivity principles. In this context, the pronounced prevalence of odd-oxidation states in less precious metals bears untapped potential for fundamentally distinct reactivity modes via metalloradical catalysis. Contrary to the well-established reactivity paradigm that organic free radicals, upon addition to a vinylcyclopropane, lead to rapid ring opening under strain release-a transformation that serves widely as a mechanistic probe (radical clock) for the intermediacy of radicals-we herein show that a metal-based radical, that is, a Ni metalloradical, triggers reversible cis/trans isomerization instead of opening.

Exploring the Effects of Local Air Pollution on Popliteal Artery Aneurysms.

A growing body of evidence highlights the effects of air pollution on chronic and acute cardiovascular diseases, such as associations between PM and several cardiovascular events. However, evidence of the impact of fine air pollutants on the development and progression of peripheral arterial aneurysms is not available. Data were obtained from the multicenter PAA outcome registry POPART and the German Environment Agency.

Deciphering Popliteal Artery Aneurysm Patient Diversity: Insights From a Cluster Analysis of the POPART Registry.

Background: Popliteal artery aneurysms (PAAs) are the most common peripheral aneurysm. However, due to its rarity, the cumulative body of evidence regarding patient patterns, treatment strategies, and perioperative outcomes is limited. This analysis aims to investigate distinct phenotypical patient profiles and associated treatment and outcomes in patients with a PAA by performing an unsupervised clustering analysis of the POPART (Practice of Popliteal Artery Aneurysm Repair and Therapy) registry.

Cannabidiol (CBD) facilitates cocaine extinction and ameliorates cocaine-induced changes to the gut microbiome in male C57BL/6JArc mice.

Cocaine use disorder (CUD) is a global health problem with no approved medications. One potential treatment target is the gut microbiome, but it is unknown if cocaine induces long-lasting effects on gut microbes. A novel therapeutic candidate for CUD, cannabidiol (CBD), can improve gut function in rodent models.

Early outcomes after post-cardiotomy extracorporeal membrane oxygenation in paediatric patients: a contemporary, binational cohort study.

Objectives: The aim of this study was to assess the early outcomes and risk factors of paediatric patients requiring extracorporeal membrane oxygenation after cardiac surgery (post-cardiotomy).

Methods: Retrospective binational cohort study from the Australia and New Zealand Congenital Outcomes Registry for Surgery database. All patients younger than 18 years of age who underwent a paediatric cardiac surgical procedure from 1 January 2013 to 31 December 2021 and required post-cardiotomy extracorporeal membrane oxygenation (PC-ECMO) in the same hospital admission were included in the study.

Effectiveness of Upadacitinib for Patients With Acute Severe Ulcerative Colitis: A Multicenter Experience.

Introduction: A significant proportion of patients with acute severe ulcerative colitis (ASUC) require colectomy.

Methods: Patients with ASUC treated with upadacitinib and intravenous corticosteroids at 5 hospitals are presented. The primary outcome was 90-day colectomy rate.

Chronic interleukin-6 mediated neuroinflammation decreases anxiety, and impaires spatial memory in aged female mice.

Introduction: Neuroinflammation is a common feature of many psychiatric disorders as well as a common underlying mechanism of neurodegenerative diseases. Sex has been shown to strongly influence the development as well as the clinical expression of these pathologies. However, there is still a neglect regarding the consideration of sex effects in rodent experiments, and a substantial underrepresentation of females in studies.

Synthesizing evidence for the external cycling of NO in high- to low-NO atmospheres.

External cycling regenerating nitrogen oxides (NO ≡ NO + NO) from their oxidative reservoir, NO, is proposed to reshape the temporal-spatial distribution of NO and consequently hydroxyl radical (OH), the most important oxidant in the atmosphere. Here we verify the in situ external cycling of NO in various environments with nitrous acid (HONO) as an intermediate based on synthesized field evidence collected onboard aircraft platform at daytime. External cycling helps to reconcile stubborn underestimation on observed ratios of HONO/NO and NO/NO by current chemical model schemes and rationalize atypical diurnal concentration profiles of HONO and NO lacking noontime valleys specially observed in low-NO atmospheres.

A Valved Expanded Polytetrafluoroethylene Conduit can Acquire Endothelium After Implantation.

We demonstrate histopathology, neointimal proliferation, and neo-endothelialization in an explanted valved expanded polytetrafluoroethylene (ePTFE) conduit 40 months postimplantation that was void of calcification and inflammation, confirmed by CD-31 positivity on immunohistochemistry. Grossly, there was no distortion with preserved leaflets and lack of calcification. Good biocompatibility, nonreactivity, and low antigenicity, combined with neointimal and endothelial layer generation within the conduit might explain the low infection rates and minimal thrombogenicity.

Factors Affecting SARS-CoV-2 IgG Production after Vaccination and/or Disease: A Large-Scale Seroprevalence Study.

This study aimed at identifying factors influencing SARS-CoV-2-specific IgG antibody levels after vaccination and/or infection. Between January 2022 and March 2023, 2000 adults (≥18 years, Salzburg, Austria) participated in this population-based seroprevalence study by providing 3 mL of blood to detect SARS-CoV-2-specific IgG antibodies using an anti-SARS-CoV-2 IgG quantitative assay and by completing a self-designed questionnaire including anthropometric factors, vaccination information, and medical history. For 77 of the participants, a time-course study up to 24 weeks post vaccination or quarantine end was performed.

Iatrogenic Anomalous Origin of the Right Pulmonary Artery From the Aorta: A Rare Complication of Ligation of Aortopulmonary Window.

An aortopulmonary window (APW) is a communication between the main pulmonary artery (MPA) and the ascending aorta in the presence of two separate semilunar valves. Surgical strategies described for the management of APW include ligation, division and suturing, patch closure of APW (transaortic or transpulmonary or transwindow), and device closure. Ligation of a type-2 APW can result in stenosis or complete closure of the right pulmonary artery (RPA) off the MPA, while leaving the aorta still opening into the RPA.
