IL-7 promotes integrated glucose and amino acid sensing during homeostatic CD4 T cell proliferation.

Interleukin (IL)-7 promotes T cell expansion during lymphopenia. We studied the metabolic basis in CD4 T cells, observing increased glucose usage for nucleotide synthesis and oxidation in the tricarboxylic acid (TCA) cycle. Unlike other TCA metabolites, glucose-derived citrate does not accumulate upon IL-7 exposure, indicating diversion into other processes.

Using an inferior decoy alternative to nudge COVID-19 vaccination.

Optimizing vaccine uptake is a public health challenge that requires the implementation of effective strategies. The asymmetric dominance (or decoy) effect describes the increasing likelihood of selecting an option when a clearly inferior alternative is offered. Therefore, we aimed to test the impact of offering decoy alternatives-less convenient vaccination appointments-on vaccination intentions.

Defining epitranscriptomic hallmarks at the host-parasite interface and their roles in virulence and disease progression in Theileria annulata-infected leukocytes.

Theileria parasites are known to induce the transformation of host bovine leukocytes, involved in rapid proliferation, evasion from apoptotic mechanisms, and increased dissemination. In this study, we reveal the involvement of mA RNA modification in T. annulata infection-induced transformation of bovine leukocytes.

Feasibility Testing of the Automatic Design of Three-Unit Implant Fixed Dental Prostheses with Different Dental CAD Software: A Pre-Clinical Pilot Trial.

The technical development of implant-supported fixed dental prostheses (iFDP) initially concentrated on the computer-aided manufacturing of prosthetic restorations (CAM). Advances in information technologies have shifted the focus for optimizing digital workflows to AI-based processes for design (CAD).

Non-Invasive Continuous Glucose Monitoring in Patients Without Diabetes: Use in Cardiovascular Prevention-A Systematic Review.

Continuous glucose monitoring (CGM) might provide immediate feedback regarding lifestyle choices such as diet and physical activity (PA). The impact of dietary habits and physical activity can be demonstrated in real time by providing continuous data on glucose levels and enhancing patient engagement and adherence to lifestyle modifications. Originally developed for diabetic patients, its use has recently been extended to a non-diabetic population to improve cardiovascular health.

Ketogenic Diet as a Nutritional Metabolic Intervention for Obsessive-Compulsive Disorder: A Narrative Review.

The substantial evidence supporting the ketogenic diet (KD) in epilepsy management has spurred research into its effects on other neurological and psychiatric conditions. Despite differences in characteristics, symptoms, and underlying mechanisms, these conditions share common pathways that the KD may influence. The KD reverses metabolic dysfunction.

On-Surface Synthesis and Characterization of Radical Spins in Kagome Graphene.

Flat bands in Kagome graphene might host strong electron correlations and frustrated magnetism upon electronic doping. However, the porous nature of Kagome graphene opens a semiconducting gap due to quantum confinement, preventing its fine-tuning by electrostatic gates. Here we induce zero-energy states into a semiconducting Kagome graphene by inserting π-radicals at selected locations.

The ARCR_Pred study was initiated to document and predict the safety and effectiveness of arthroscopic rotator cuff repair (ARCR) in a representative Swiss patient cohort. In the present manuscript, we aimed to describe the overall and baseline characteristics of the study, report on functional outcome data and explore case-mix adjustment and differences between public and private hospitals. Between June 2020 and November 2021, primary ARCR patients were prospectively enrolled in a multicenter cohort across 18 Swiss and one German orthopedic center.

Skin-Integrated Electrogenetic Regulation of Vasculature for Accelerated Wound Healing.

Neo-vascularization plays a key role in achieving long-term viability of engineered cells contained in medical implants used in precision medicine. Moreover, strategies to promote neo-vascularization around medical implants may also be useful to promote the healing of deep wounds. In this context, a biocompatible, electroconductive borophene-poly(ε-caprolactone) (PCL) 3D platform is developed, which is called VOLT, to support designer cells engineered with a direct-current (DC) voltage-controlled gene circuit that drives secretion of vascular endothelial growth factor A (VEGFA).

Carotid artery atherosclerosis: mechanisms of instability and clinical implications.

Cardiovascular disease remains a prominent cause of disability and premature death worldwide. Within this spectrum, carotid artery atherosclerosis is a complex and multifaceted condition, and a prominent precursor of acute ischaemic stroke and other cardiovascular events. The intricate interplay among inflammation, oxidative stress, endothelial dysfunction, lipid metabolism, and immune responses participates in the development of lesions, leading to luminal stenosis and potential plaque instability.

Semi-field experiments reveal contrasted predation and movement patterns of aquatic macroinvertebrate predators of Anopheles gambiae larvae.

Background: Members of the Anopheles gambiae complex are major malaria vectors in sub-Saharan Africa. Their larval stages inhabit a variety of aquatic habitats in which, under natural circumstances, they are preyed upon by different taxa of aquatic macroinvertebrate predators. Understanding the potential impact of predators on malaria vector larval population dynamics is important for enabling integrated local mosquito control programmes with a stronger emphasis on biocontrol approaches.

At the crossroads of biology and electronics.

All cells are innately equipped with systems to detect and respond to electrical inputs in the form of reactive oxygen species, redox signaling, or membrane depolarization through ion exchange. Electrogenetics aims to leverage these cellular systems to create interfaces between biology and electronics, in order to achieve levels of precision in spatiotemporal control of gene and protein expression that are not possible with chemo-, opto-, or thermogenetics. In this review, we discuss the impact, challenges, and prospects of electrogenetics in the context of recent cutting-edge applications.

Like milk on the stove: Healthcare professionals navigating uncertainty when caring for families with 22q11DS.

Introduction: 22q11 deletion syndrome (22q11DS) results from a microdeletion on chromosome 22 and is the most common microdeletion disorder in humans, affecting 1 in 2148 live births. Clinical manifestations vary widely among individuals and across different life stages. Effective management requires the involvement of a specialized multidisciplinary team.

Multiplicity of type 6 secretion system toxins limits the evolution of resistance.

The bacterial type 6 secretion system (T6SS) is a toxin-injecting nanoweapon that mediates competition in plant- and animal-associated microbial communities. Bacteria can evolve de novo resistance against T6SS attacks, but resistance is far from universal in natural communities, suggesting key features of T6SS weaponry may act to limit its evolution. Here, we combine ecoevolutionary modeling and experimental evolution to examine how toxin type and multiplicity in attackers shape resistance evolution in susceptible competitors.

Associations between Insomnia Severity, Perceived Stress, Mental Toughness, Dark Triad Traits, and Organizational Citizenship Behavior among Cadets of the Swiss Armed Forces.

The present study: (1) compared categories of insomnia severity between cadets of the Swiss Armed Forces (SAF) and previously published norms and (2) investigated the associations between insomnia and psychological well-being related to perceived stress, mental toughness, dark triad traits, and organizational citizenship behavior (OCB).

Methods: A total of 216 cadets of the SAF (mean age: 20.

Is mesh related morbidity the real thread in ventral rectopexy? Results of a retrospective international multicentre comparative analysis of biologic versus synthetic mesh.

Aim: Ventral mesh rectopexy (VMR) is an established surgical treatment for rectal prolapse and outlet obstruction. In contrast to continental Europe, in the UK and US the use of synthetic mesh has been abandoned in favour of biologic mesh, due to concerns regarding mesh related morbidity. The current study investigated if either material is superior, in terms of clinical recurrence and mesh related complications.

A combined school survey and reactive case detection reveals minimal local transmission of malaria in the Highlands Region of Papua New Guinea.

Background: The Highlands of Papua New Guinea are non-endemic for malaria compared to the rest of the country. This study aimed to explore the local transmission of malaria in the Highlands through a cross-sectional school survey coupled with reactive case detection.

Methods: Between July and November 2019, 5575 schoolchildren and 1048 household members were screened for malaria using Rapid Diagnostic Tests, subsequently validated by light microscopy.

Insights into Treponema pallidum genomics from modern and ancient genomes using a novel mapping strategy.

Background: Treponemal diseases are a significant global health risk, presenting challenges to public health and severe consequences to individuals if left untreated. Despite numerous genomic studies on Treponema pallidum and the known possible biases introduced by the choice of the reference genome used for mapping, few investigations have addressed how these biases affect phylogenetic and evolutionary analysis of these bacteria. In this study, we ascertain the importance of selecting an appropriate genomic reference on phylogenetic and evolutionary analyses of T.

High-efficiency base editing in the retina in primates and human tissues.

Stargardt disease is a currently untreatable, inherited neurodegenerative disease that leads to macular degeneration and blindness due to loss-of-function mutations in the ABCA4 gene. We have designed a dual adeno-associated viral vector encoding a split-intein adenine base editor to correct the most common mutation in ABCA4 (c.5882G>A, p.

The effect of mortality salience and early-life maternal care on neuroendocrine, autonomic, and psychological stress responses.

Adverse early-life experiences alter the regulation of major stress systems such as the hypothalamic-pituitary-adrenal (HPA) axis. Low early-life maternal care (MC) has repeatedly been related to blunted cortisol stress responses. Likewise, an acutely increased awareness of mortality (mortality salience [MS]) also has been shown to blunt cortisol responses.

Determination of Ventilatory Thresholds Using Near-Infrared Spectroscopy in Recreational Endurance and CrossFit Athletes.

To define training zones, ventilatory thresholds (VTs) are commonly established by cardiopulmonary gas-exchange analysis during incremental exercise tests. Portable near-infrared spectroscopy (NIRS) devices have emerged as a potential tool for detecting these thresholds by monitoring muscle oxygenation. This study evaluated the accuracy of NIRS measurements to determine VTs or critical power (CP) based on muscle oxygen saturation and assesses the device's consistency across 2 constant-load tests.

Distinct subtypes of post-transplant lymphoproliferative disorders: CHIP-like mutations in early lesions and substantial mutational differences between EBV-positive and EBV-negative diffuse large B-cell lymphomas.

Post-transplant lymphoproliferative disorders (PTLD) and lymphomas in immunocompromised individuals represent significant clinical challenges, with a limited understanding of their pathogenesis. We investigated a PTLD cohort (n = 50) consisting of 'early lesions' (infectious mononucleosis-like PTLD, plasmacytic and follicular hyperplasias), polymorphic PTLD and post-transplant diffuse large B-cell lymphomas (PT-DLBCL). The study also included 15 DLBCL with autoimmune/immunocompromised backgrounds (IS-DLBCL) and 14 DLBCL, not otherwise specified (DLBCL, NOS), as control.

Serum Pentosidine in Relation to Obesity in Patients with Type 2 Diabetes and Healthy Controls.

Pentosidine (PEN), a surrogate marker of advanced glycation end-product formation, reflects increased non-enzymatic cross-linking in bone collagen, which is thought to be an important determinant of bone fragility in type 2 diabetes mellitus (T2DM). We aimed to investigate serum concentrations of PEN in patients with T2DM and controls without T2DM and to examine its relationship with bone parameters and metabolic state such as glycaemic control, insulin resistance and body weight. In a cross-sectional study-design, data from postmenopausal women and men with T2DM (n = 110) and controls without T2DM (n = 111) were evaluated.
