Resistance training protects the hippocampus and precuneus against atrophy and benefits white matter integrity in older adults with mild cognitive impairment.

Mild cognitive impairment (MCI) refers to cognitive alterations with preservation of functionality. Individuals with this diagnosis have a higher risk of developing dementia. Non-pharmacological interventions, such as physical exercise, are beneficial for the cognition of this population.

Patterning Functional Proteins in Ultrabithorax-Based Materials.

The ability to add bioactivities, such as cell signaling or ligand recognition, to biomaterials has generated the potential to include multiple bioactivities into a single material. In some cases, it is desirable to localize these activities to different areas of the biomaterial, creating functional patterns. While photolithography and 3D printing have been effective techniques for patterning functions in many materials, patterning remains a challenge in materials composed of protein, in part due to how these materials are artificially assembled.

Studying the Role of HOX Genes in Thrombocyte Development.

In our laboratory, we study thrombopoiesis and hemostasis using zebrafish as a model organism to unravel the mechanisms of differentiation and development of thrombocytes. We have shown in our earlier work that thrombocytes are functional equivalents of platelets and have transcriptional machinery similar to megakaryocytes. We recently found evidence that hox genes play a role in their development.

Psychometric evaluation of the Yale-Brown Obsessive-Compulsive Scale in pregnant women.

Purpose: Although many women experience obsessive-compulsive symptoms during the perinatal period, the Yale-Brown Obsessive Compulsive Scale (YBOCS) has not yet been psychometrically evaluated in this population. This study examined the internal consistency, convergent and divergent validity, and factor structure of the YBOCS among pregnant women.

Methods: 256 Women who were 20 to 24 weeks pregnant completed the clinician-administered YBOCS and Mini International Neuropsychiatric Interview (MINI) along with a series of self-report questionnaires including the Edinburgh Postnatal Depression Scale (EPDS), Perinatal Anxiety Screening Scale (PASS) and Obsessive-Compulsive Inventory-Revised (OCI-R).

Cardiac MRI Evaluation of Determinants and Prognostic Implications of Right Ventricular Dysfunction in Aortic Regurgitation.

Purpose To investigate the determinants and effect of right ventricular (RV) dysfunction in aortic regurgitation (AR) using cardiac MRI. Materials and Methods This study included patients with moderate or severe AR who were enrolled in the DEBAKEY-CMR registry between January 2009 and June 2020. Patients with previous valve intervention, cardiomyopathy deemed unrelated to AR, severe aortic stenosis, and other confounders were excluded.

Potential of phosphodiesterase 4B inhibition in the treatment of progressive pulmonary fibrosis.

Idiopathic pulmonary fibrosis (IPF) is often regarded as the archetypal progressive fibrosing interstitial lung disease (ILD). The term "progressive pulmonary fibrosis" (PPF) generally describes progressive lung fibrosis in an individual with an ILD other than IPF. Both IPF and PPF are associated with loss of lung function, worsening dyspnea and quality of life, and premature death.

The Role of Gender in the Relationship Between Negative Reactions to Sexual Abuse Disclosure and Masculinity Norm Adherence.

Although men and women generally receive positive and negative reactions to childhood sexual abuse (CSA) disclosure (Filipas & Ullman, 2001), negative reactions are more common (Gagnier & Collin-Vézina, 2016). Negative disclosure reactions - such as disbelieving, retaliating against, or distracting the survivor - are both prevalent and associated with poorer post-abuse recovery and well-being (Kennedy & Prock, 2018; Ullman, 2010). For male survivors in particular, the responses one receives from others following disclosure may complicate one's sense of masculinity.

Printing rare-earth-free (REF) magnetic inks: synthesis, formulation, and device applications.

Additive manufacturing (AM) of magnetic materials has recently attracted increasing interest for various applications but is often limited by the high cost and supply chain risks of rare-earth-element (REE) magnetic precursors. Recent advances in nanomanufacturing have enabled the development of rare-earth-free (REF) magnetic materials, such as spinel ferrites, hexaferrites, MnAl, MnBi, Alnico, FePt, and iron oxides/nitrides, which offer promising alternatives for printing high-performance magnetic devices. This review provides a detailed overview of the latest developments in REF magnetic materials, covering both synthesis strategies of REF magnetic materials/nanomaterials and their integration into AM processes.

Sex-Based Differences in Endovascular Thrombectomy Outcomes for Large Ischemic Stroke: A SELECT2 Subanalysis.

Background: Several social and biological factors are shown to differentially affect stroke outcomes between men and women. We evaluated whether clinical outcomes and endovascular thrombectomy (EVT) treatment effects differed between the sexes in patients presenting with large ischemic stroke.

Methods: The SELECT2 trial (A Randomized Controlled Trial to Optimize Patient's Selection for Endovascular Treatment in Acute Ischemic Stroke) was a randomized controlled trial assessing the efficacy and safety of EVT in patients with large strokes across the United States, Canada, Europe, Australia, and New Zealand between October 2019 and September 2022.

Activating the Basal Planes of TiC MXene for Accelerated Ammonia Electrosynthesis: Role of Surface Terminations.

Altering the edge sites of 2D MXenes for electrochemical dinitrogen reduction reaction (ENRR) is widely reported, whereas activation of its relatively inert basal planes is neglected. Herein, the activation and the optimization of the basal planes of TiCT (T = *F, *O, and *OH) MXenes toward enhanced ENRR to ammonia is reported. The balanced surface functionalization in TiCT regulates the ENRR kinetics by regulating the potential of zero charge (E) and the electrochemical work function ( ).

Inhibition of nitric oxide synthase transforms carotid occlusion-mediated benign oligemia into large cerebral infarction.

It remains unclear why unilateral proximal carotid artery occlusion (UCAO) causes benign oligemia in mice, yet leads to various outcomes (asymptomatic-to-death) in humans. We hypothesized that inhibition of nitric oxide synthase (NOS) both transforms UCAO-mediated oligemia into full infarction and expands pre-existing infarction. Using 900 mice, we i) investigated stroke-related effects of UCAO with/without intraperitoneal administration of the NOS inhibitor (NOSi) N-nitro-L-arginine methyl ester (L-NAME, 400 mg/kg); ii) examined the rescue effect of the NO-donor, molsidomine (200 mg/kg at 30 minutes); and iii) tested the impact of antiplatelet medications.

Melanoma toolkit for early detection for primary care clinicians: a 1-year follow-up on outcomes.

Introduction: Primary care providers or clinicians (PCPs) have the potential to assist dermatologists in screening patients at risk for skin cancer, but require training to appropriately identify higher-risk patients, perform skin checks, recognize and biopsy concerning lesions, interpret pathology results, document the exam, and bill for the service. Very few validated dermatology training programs exist for PCPs and those that are available focus primarily on one emphasis area, which results in variable efficacy and single-topic limited scope.

Methods: We have created a free, online, continuing education program (Melanoma Toolkit for Early Detection, MTED) that allows learners to choose from a variety of multimedia tools (image recognition, videos, written material, in-person seminars, self-tests, etc.

Prescribing Patterns of Gabapentinoids in Chronic Pain Management: A Single Institution Retrospective Chart Review.

Gabapentin and pregabalin are widely used in the management of neuropathic pain though their prescribing patterns, effectiveness, and safety profiles remain topics of ongoing research. This retrospective chart review analyzed the prevalence of gabapentinoid use in a chronic pain clinic over a one-year period from May 1, 2023, to April 30, 2024. The study examined patient records from four pain management physicians, focusing on those prescribed gabapentin or pregabalin.

Long-term impact of Diabetes Prevention Program interventions on walking endurance.

Objectives: Type 2 diabetes (T2D) and prediabetes are associated with poor walking endurance, a marker of physical function. We aimed to examine the long-term effects of metformin or intensive lifestyle intervention in adults at high risk of T2D on their 6-min walk test (6MWT) performance.

Methods: Participants were randomized in the 3-year Diabetes Prevention Program (DPP) to one of the three groups: lifestyle intervention, metformin, or placebo, and were subsequently followed in the DPP Outcomes Study.

Tumor immunomodulation by nanoparticle and focused ultrasound alters gut microbiome in a sexually dimorphic manner.

Local immunomodulation with nanoparticles (NPs) and focused ultrasound (FUS) is recognized for triggering anti-tumor immunity. However, the impact of these tumor immunomodulations on sex-specific microbiome diversity at distant sites and their correlation with therapeutic effectiveness remains unknown. Here, we conducted local intratumoral therapy using immunogenic cell death-enhancing Calreticulin-Nanoparticles (CRT-NPs) and FUS in male and female mice.

Microgel-Guided MXene Assembly for High-Performance, Low-Solid Content Conductive Inks.

Rapid evolution of smart devices necessitates high-performance, lightweight materials for effective electromagnetic interference (EMI) shielding. TiCT MXene nanosheets are promising for such applications, yet the high solid content typically required for 3D-printable MXene inks limits their scalability and cost efficiency. In this study, we present an MXene-based ink with an ultralow solid content (0.

The effect of a provisional diagnosis on intern diagnostic reasoning: a mixed methods study.

Objectives: Competency in diagnostic reasoning is integral to medical training and patient safety. Situativity theory highlights the importance of contextual factors on learning and performance, such as being informed of a provisional diagnosis prior to a patient encounter. This study aims to determine how being informed of a provisional diagnosis affects an intern's approach to diagnostic reasoning.

Streamlining Global Germplasm Exchange: Integrating Scientific Rigor and Common Sense to Exclude Phantom Agents from Regulation.

This collaborative work by over 180 researchers from 40+ countries addresses the challenges posed by "phantom agents"-putative pathogenic agents named in literature without supporting data on their existence. Those agents remain on regulatory lists, creating barriers in trade and plant certification. Historically identified based solely on symptoms, these agents lack isolates or sequence data, making reliable detection or risk assessment impossible.

Critical procedural steps in intrauterine transfusion: Delphi survey of international experts.

Objective: To determine consensus, using Delphi methodology, on the critical procedural steps for intravascular intrauterine transfusion (IUT) for the treatment of fetal anemia.

Methods: We conducted a two-part Delphi survey of international experts in fetal intervention. The first round of the survey proposed 32 potentially critical steps for the IUT procedure.

Magnetospheric origin of a fast radio burst constrained using scintillation.

Fast radio bursts (FRBs) are microsecond-to-millisecond-duration radio transients that originate mostly from extragalactic distances. The FRB emission mechanism remains debated, with two main competing classes of models: physical processes that occur within close proximity to a central engine; and relativistic shocks that propagate out to large radial distances. The expected emission-region sizes are notably different between these two types of models.

Monoallelic expression can govern penetrance of inborn errors of immunity.

Inborn errors of immunity (IEIs) are genetic disorders that underlie susceptibility to infection, autoimmunity, autoinflammation, allergy and/or malignancy. Incomplete penetrance is common among IEIs despite their monogenic basis. Here we investigate the contribution of autosomal random monoallelic expression (aRMAE), a somatic commitment to the expression of one allele, to phenotypic variability observed in families with IEIs.

Aspartate signalling drives lung metastasis via alternative translation.

Lung metastases occur in up to 54% of patients with metastatic tumours. Contributing factors to this high frequency include the physical properties of the pulmonary system and a less oxidative environment that may favour the survival of cancer cells. Moreover, secreted factors from primary tumours alter immune cells and the extracellular matrix of the lung, creating a permissive pre-metastatic environment primed for the arriving cancer cells.

Pivotal roles of biglycan and decorin in regulating bone mass, water retention, and bone toughness.

Proteoglycans, key components of non-collagenous proteins in the bone matrix, attract water through their negatively charged glycosaminoglycan chains. Among these proteoglycans, biglycan (Bgn) and decorin (Dcn) are major subtypes, yet their distinct roles in bone remain largely elusive. In this study, we utilized single knockout (KO) mouse models and successfully generated double KO (dKO) models despite challenges with low yield.
