Idiopathic Systemic Capillary Leak Syndrome (ISCLS) is a poorly understood paroxysmal permeability disorder. This study aimed to characterize the clinical features and severity markers of ISCLS in critically and non-critically ill patients. We analyzed prospectively and retrospectively collected data on ISCLS cases from the Italian IRIS-CLS Registry (January 1995-December 2023).

Recognition of MR1-antigen complexes by TCR Vγ9Vδ2.

The TCR-mediated activation of T cells expressing the TCR Vγ9Vδ2 relies on an innate-like mechanism involving the butyrophilin 3A1, 3A2 and 2A1 molecules and phospho-antigens, without the participation of classical antigen-presenting molecules. Whether TCR Vγ9Vδ2 cells also recognize complexes composed of antigens and antigen-presenting molecules in an adaptive-like manner is unknown. Here, we identify MR1-autoreactive cells expressing the TCR Vγ9Vδ2.

Responses of Arbuscular Mycorrhizal Fungi and Plant Communities to Long-Term Mining and Passive Restoration.

Mining activities cause strong soil alterations, such as heavy metal (HM) pollution, which decreases the diversity of plant communities and rhizospheric microorganisms, including arbuscular mycorrhizal (AM) fungi. The polymetallic Paramillos de Uspallata mine in the Andes Mountains, the first mining exploitation in Argentina, provides a unique scenario to study AM fungal resilience after long-term disturbance following over 40 years of inactivity. This study aimed to analyze mycorrhizal status and AM fungal communities in the mine and a nearby unexploited area and to evaluate their associations with soil parameters to elucidate life history strategies.

Rewriting nuclear epigenetic scripts in mitochondrial diseases as a strategy for heteroplasmy control.

Mitochondrial diseases, caused by mutations in either nuclear or mitochondrial DNA (mtDNA), currently have limited treatment options. For mtDNA mutations, reducing mutant-to-wild-type mtDNA ratio (heteroplasmy shift) is a promising therapeutic option, though current approaches face significant challenges. Previous research has shown that severe mitochondrial dysfunction triggers an adaptive nuclear epigenetic response, characterized by changes in DNA methylation, which does not occur or is less important when mitochondrial impairment is subtle.

Comparison of neuraminidase inhibiting antibody responses elicited by egg- and cell-derived influenza vaccines.

Unlabelled: Neuraminidase (NA)-specific antibodies contribute to immunity against influenza. While studies have demonstrated increased NA inhibiting (NAI) antibody titers after vaccination with egg-derived inactivated influenza vaccines (eIIV), the response to cell culture-derived (c) IIV has not been reported.

Methods: An immunogenicity sub-study was performed within a clinical trial comparing the effectiveness of egg, cell, and recombinant hemagglutinin (HA)-derived influenza vaccines during the 2018-2019 and 2019-2020 influenza seasons.

Identifying optimal candidates for active surveillance in low-grade intermediate-risk non-muscle invasive bladder cancer.

The carbonyl nucleobase adduct MAde is a potent antigen for adaptive polyclonal MR1-restricted T cells.

The major histocompatibility complex (MHC) class I-related molecule MHC-class-I-related protein 1 (MR1) presents metabolites to distinct MR1-restricted T cell subsets, including mucosal-associated invariant T (MAIT) and MR1T cells. However, self-reactive MR1T cells and the nature of recognized antigens remain underexplored. Here, we report a cell endogenous carbonyl adduct of adenine (8-(9H-purin-6-yl)-2-oxa-8-azabicyclo[3.

Non-surgical management of BPH: An updated review of current literature and state of the art on natural compounds and medical therapy.

Introduction: Benign prostatic hyperplasia (BPH) is a common urological disease that is strongly associated with the aging process and can lead to lower urinary tract symptoms (LUTS). LUTS due to BPH can significantly affect the quality of life of many patients. Among the treatments available for BPH to improve symptoms and functional outcomes, drug therapy and surgical therapy are the options of choice.

Sustainable photocatalytic degradation of antibiotic norfloxacin using microfibrillated cellulose@ZnO nanocomposites.

Antibiotics from the fluoroquinolone class, such as norfloxacin (NOR), are emerging contaminants with significant environmental and human health impacts. Their safe degradation from water remains a global challenge due to their persistence, lack of biodegradability, and ability to induce resistant bacteria. To the best of our knowledge, for the first time, this work reports the development of highly efficient photocatalytic degradation of NOR using environmentally friendly microfibrillated cellulose@ZnO (MFC@ZnO) photocatalysts.

The Impact of Frailty on Patients With AF and HFrEF Undergoing Catheter Ablation: A Nationwide Population Study.

Background: Frailty is a common geriatric syndrome often coexisting with cardiovascular diseases such as atrial fibrillation (AF) and heart failure (HF) with reduced ejection fraction (HFrEF). While catheter ablation (CA) has demonstrated efficacy in reducing major adverse cardiovascular events and improving mortality and quality of life, the influence of frailty among this population remains unknown.

Objectives: The authors aimed to identify the prevalence of frailty among patients with HFrEF and AF undergoing CA and its influence on cardiovascular mortality and discharge disposition.

Molecular signature underlying (R)-ketamine rapid antidepressant response on anhedonic-like behavior induced by sustained exposure to stress.

Anhedonia induced by sustained stress exposure is a hallmark symptom of major depressive disorder (MDD) and in rodents, it can be accessed through the sucrose preference test (SPT). (R)-ketamine is a fast-acting antidepressant with less detrimental side effects and abuse liability compared to racemic ketamine. The present study combined high-throughput proteomics and network analysis to identify molecular mechanisms involved in chronic variable stress (CVS)-induced anhedonia and promising targets underlying (R)-ketamine rapid antidepressant response.

Performance of rapid antigen tests to detect SARS-CoV-2 variant diversity and correlation with viral culture positivity: implication for diagnostic development and future public health strategies.

Unlabelled: Antigen-based rapid diagnostic tests (Ag-RDTs) provide timely results, are simple to use, and are less expensive than molecular assays. Recent studies suggest that antigen-based testing aligns with virus culture-based results (a proxy of contagiousness at the peak viral phase of illness); however, the performance of Ag-RDTs for newer SARS-CoV-2 variants is unclear. In this study, we (i) assessed the performance of Ag-RDTs and diagnostic antibodies to detect a range of SARS-CoV-2 variants and (ii) determined whether Ag-RDT results correlated with culture positivity.

Spanning over 40 years, ADC clinical development has enhanced our understanding of the multifaceted mechanisms of action for this class of therapeutics. In this article, we discuss key insights into the toxicity, efficacy, stability, distribution, and fate of ADCs.

Conductance Channels in a Single-Entity Enzyme.

For a long time, the prevailing view in the scientific community was that proteins, being complex macromolecules composed of amino acid chains linked by peptide bonds, adopt folded structure with insulating or semiconducting properties, with high bandgaps. However, recent discoveries of unexpectedly high conductance levels, reaching values in the range of dozens of nanosiemens (nS) in proteins, have challenged this conventional understanding. In this study, we used scanning tunneling microscopy (STM) to explore the single-entity conductance properties of enzymatic channels, focusing on bilirubin oxidase (BOD) as a model metalloprotein.

Micro PIXE mapping proves a differential distribution and concentration of trace elements in fungal structures of Rhizophagus intraradices.

Arbuscular mycorrhizal (AM) fungi can sequester different potentially toxic elements, such as trace elements (TEs), within their structures to alleviate the toxicity for its host plant and themselves. To elucidate the role of AM fungi in TEs immobilization in the rhizosphere of host plants, it is important to know the TEs distribution in AM fungal structures. In the present study, we investigated the distribution and concentration of TEs within extraradical spores and mycelium of the AM fungus Rhizophagus intraradices, collected from the rhizosphere of Senecio bonariensis plants grown in a soil polluted with multiple TEs, by using Particle-Induced X-ray Emission with a micro-focused beam (micro PIXE).
