Mineral Stress Drives Loss of Heterochromatin: An Early Harbinger of Vascular Inflammaging and Calcification.

Background: Vascular calcification is a detrimental aging pathology markedly accelerated in patients with chronic kidney disease. Prelamin A is a biomarker of vascular smooth muscle cell aging that accelerates calcification however the mechanisms remain undefined.

Methods: Vascular smooth muscle cells were transduced with prelamin A using an adenoviral vector and epigenetic modifications were monitored using immunofluorescence and targeted polymerase chain reaction array.

Masticatory muscle changes on magnetic resonance imaging of dogs with compared to meningoencephalitis of unknown origin.

Infectious meningoencephalitides represent an important differential diagnosis for meningoencephalitis of unknown origin (MUO) in dogs. Treatment of the latter requires immunosuppression, but laboratory test results for infectious agents may take several days to return. This study investigated whether the presence of masticatory muscle changes on magnetic resonance imaging (MRI) of the head can be used to distinguish dogs with neosporosis from those with MUO at the time of diagnosis.

Developing and evaluating a health pack to support dog owners to manage the weight of their companion animals.

Introduction: Obesity is a serious and prevalent problem in dogs. The causes are multifactorial, but owners play a key role and so this paper reports the development and evaluation of a health pack designed to help owners to manage the weight of their dogs.

Method: The pack was informed by previous research, behavior change theory (i.

Revealing the zone of possible agreement between parties in conflict: An application to Israeli-Palestinian peace agreements.

After Hamas' attack on 2023 October 7 and Israel's subsequent war, a pressing question is the nature of a postwar peace agreement. Peace negotiations often become deadlocked due to difficulties in identifying mutually advantageous agreements. A large-scale survey task and method is developed to identify the strength of preference for components of potential peace deals and changes to the status quo.

Loading rate, geometry, and damage state influence vertical extraction biomechanics in an ex vivo swine dental model.

Introduction: Validated models describing the biomechanics of tooth extraction are scarce. This study seeks to perform experimental and numerical characterization of vertical tooth extraction biomechanics in swine incisors with imposed vertical extraction loads. Imaging analysis related mechanical outcomes to tooth geometry and applied loading rate.

War and peace: exploring microbial defence systems as a source of new antimicrobial therapies.

The WHO has compiled a list of pathogens that urgently require new antibiotics in response to the rising reports of antibiotic resistance and a diminished supply of new antibiotics. At the top of this list is fluoroquinolone-resistant , fluoroquinolone-resistant spp. and vancomycin-resistant .

A novel oncolytic Vaccinia virus armed with IL-12 augments antitumor immune responses leading to durable regression in murine models of lung cancer.

Oncolytic vaccinia viruses (VVs) are potent stimulators of the immune system and induce immune-mediated tumor clearance and long-term surveillance against tumor recurrence. As such they are ideal treatment modalities for solid tumors including lung cancer. Here, we investigated the use of VVL-m12, a next-generation, genetically modified, interleukin-12 (IL-12)-armed VV, as a new therapeutic strategy to treat murine models of lung cancer and as a mechanism of increasing lung cancer sensitivity to antibody against programmed cell death protein 1 (α-PD1) therapy.

Midfoot fractures: Patterns of injury and predictors of stability.

Background: Lisfranc injuries describe a spectrum of midfoot and tarsometatarsal joint (TMTJ) trauma ranging from purely ligamentous to multiple fracture-dislocations. Lisfranc injuries represent 0.2 % of all fractures and are seen predictably, with mechanisms involving a fall from height, crushing, or torsion.

"Longing is good": proof-of-concept for a novel psychological intervention to tackle self-blaming emotions.

Background: Many people with depression, for which self-blame plays a key role, are not amenable to current standard psychological treatments. This calls for novel self-guided interventions, which require less attention and motivation. The present study sought to establish proof-of-concept for a novel self-guided intervention in a non-clinical sample, which prompts people to transform self-blaming feelings into "longing," as a related unpleasant, but presumably more adaptive and approach-related emotion, which plays a key role in many musical and literary genres but has been largely overlooked in clinical research.

Monitoring Radical Intermediates in Photoactivated Palladium-Catalyzed Coupling of Aryl Halides to Arenes by an Aryl Radical Assay.

An aryl radical assay is used to provide information about the formation of aryl radicals from aryl halides in coupling reactions to arenes in the presence of palladium sources and under LED irradiation (λ = 456 nm). The assay uses 2-halo--xylenes as substrates. Aryl radical formation is indicated both by a defined product composition and by signature deuterium isotope effects.

Recommendations for reporting and evaluating proton therapy beyond dose and constant relative biological effectiveness.

Background And Purpose: In proton therapy, a relative biological effectiveness (RBE) of 1.1 is used to convert proton dose into an equivalent photon dose. However, RBE varies with tissue type, fraction dose, and beam quality parameters beyond dose such as linear energy transfer (LET) raising concerns about increased local effectiveness and potential toxicity.

Abnormally Low HbA Caused by Hemolytic Anemia, a Case Report and Literature Review.

Hemoglobin A is a widely used diagnostic tool for monitoring glycemic control in diabetes management. However, its accuracy can be influenced by various factors. We present a case of a 17-year-old boy with abnormally low Hemoglobin A levels caused by warm autoantibody-induced hemolytic anemia.

AI predicting recurrence in non-muscle-invasive bladder cancer: systematic review with study strengths and weaknesses.

Background: Non-muscle-invasive Bladder Cancer (NMIBC) is notorious for its high recurrence rate of 70-80%, imposing a significant human burden and making it one of the costliest cancers to manage. Current prediction tools for NMIBC recurrence rely on scoring systems that often overestimate risk and lack accuracy. Machine learning (ML) and artificial intelligence (AI) are transforming oncological urology by leveraging molecular and clinical data to enhance predictive precision.

Expanding the genomic diversity of human anelloviruses.

Anelloviruses are a group of small, circular, single-stranded DNA viruses that are found ubiquitously across mammalian hosts. Here, we explored a large number of publicly available human microbiome datasets and retrieved a total of 829 anellovirus genomes, substantially expanding the known diversity of these viruses. The majority of new genomes fall within the three major human anellovirus genera: , and , while we also present new genomes of the under-sampled , and genera.

From shadowing to active learning: exploring the impact of supervised teaching clinics on gynecology education.

Background: Supervised Teaching Clinics (STCs) have emerged as an innovative approach to medical education, particularly in specialties like gynecology, where hands-on experience is crucial. Traditional clinical rotations often leave students in passive roles, limiting their active participation and the development of essential clinical skills.

Aim: This study aimed to evaluate the impact of STCs on the clinical competencies and professional development of medical students within a gynecological clinic, comparing the outcomes with those of traditional clinic shadowing.

Introduction: Human T-cell lymphotropic virus type 1 (HTLV-1) may cause spinal cord inflammation, leading to HTLV-1-associated myelopathy (HAM). HAM is a chronic and progressive neurological disorder that is associated with increased mortality and impaired quality of life. There are limited data on the incidence of HAM, with higher rates seen in Latin America and the Caribbean compared to Japan.

Positive end-expiratory pressure increases intracranial pressure but not pressure reactivity index in supine and prone positions: a porcine model study.

Introduction: Positive end-expiratory pressure (PEEP) and prone positioning can improve gas exchange by promoting uniform lung aeration. However, elevated ventilation pressures may increase intracranial pressure (ICP) and disrupt cerebral autoregulation. This study investigated the effects of PEEP on ICP and cerebral autoregulation in a porcine model with healthy lungs and normal ICP, comparing prone and supine positions.
