Background: Enterovirus 71 (EV71) is one of the major causative agents of hand, foot, and mouth disease (HFMD), and can cause severe cerebral complications and even fatality in children younger than 5 years old. However, there is no specific medication for EV71 infection in clinical practice. Our previous studies had identified the 6-thioguanine (6-TG), an FDA-approved anticancer drug, as a potential antiviral agent, but its anti-EV71 activity is largely unknown, therefore, we aim to explore the antiviral effect of 6-TG on EV71.

Early investigation revealed a reduced risk of SARS-CoV-2 infection among social contacts of COVID-19 vaccinated individuals, referred to as indirect protection. However, indirect protection from SARS-CoV-2 infection-acquired immunity and its comparative strength and durability to vaccine-derived indirect protection in the current epidemiologic context of high levels of vaccination, prior infection, and novel variants are not well characterized. Here, we show that both vaccine-derived and infection-acquired immunity independently yield indirect protection to close social contacts with key differences in their strength and waning.

Black men suffer disproportionately from prostate cancer (PCa) compared to men of other races and ethnicities. Comparing the molecular landscape of PCa among Black and White patients has the potential to identify targets for development of new precision medicine interventions. Herein, we conducted transcriptomic analysis of prostate tumors and paired tumor-adjacent normals from self-reported Black and White PCa patients and estimated patient genetic ancestry.

Blood transfusion plays a vital role in modern medicine, but frequent shortages occur. Ex vivo manufacturing of red blood cells (RBCs) from universal donor cells offers a potential solution, yet the high cost of recombinant cytokines remains a barrier. Erythropoietin (EPO) signaling is crucial for RBC development, and EPO is among the most expensive media components.

ETV6::RUNX1 is the most common fusion gene in childhood acute lymphoblastic leukemia (ALL) associated with favorable prognosis, but the optimal therapy for this subtype remains unclear. Profiling the genomic and pharmacological landscape of 194 pediatric ETV6::RUNX1 ALL cases, we uncover two transcriptomic clusters, C1 (61%) and C2 (39%). Compared to C1, the C2 subtype features higher white blood cell counts and younger age at diagnosis, as well as better early treatment responses.

Time-resolved Brownian tomography of single nanocrystals in liquid during oxidative etching.

Nat Commun

January 2025

School of Chemical and Biological Engineering, Institute of Chemical Processes, Seoul National University, Seoul, Republic of Korea.

Colloidal nanocrystals inherently undergo structural changes during chemical reactions. The robust structure-property relationships, originating from their nanoscale dimensions, underscore the significance of comprehending the dynamic structural behavior of nanocrystals in reactive chemical media. Moreover, the complexity and heterogeneity inherent in their atomic structures require tracking of structural transitions in individual nanocrystals at three-dimensional (3D) atomic resolution.

Myosin Heavy Chain Myopathy and Immune-Mediated Muscular Disorders.

Vet Clin North Am Equine Pract

January 2025

Large Animal Clinical Sciences, College of Veterinary Medicine, Michigan State University, East Lansing, MI, USA.

Several inflammatory myopathies have an infectious or immune-mediated basis in the horse. Myosin heavy chain myopathy is caused by a codominant missense variant in MYH1 and has 3 clinical presentations: immune-mediated myositis, calciphylaxis, and nonexertional rhabdomyolysis in Quarter Horse-related breeds. An infarctive form of purpura hemorrhagica affects numerous breeds, presenting with focal firm, painful muscle swelling, and subsequent infarction of multiple tissues.

Background: The vascular and cardiometabolic effects of pecans are relatively under-studied.

Objectives: The aim was to examine how substitution of usual snack foods with 57 g/day of pecans affects vascular health, risk factors for cardiometabolic diseases and diet quality, compared to continuing usual intake in individuals at risk for cardiometabolic diseases.

Methods: A 12-week single-blinded, parallel, randomized controlled trial was conducted.

Objective: To assess the effectiveness of an mHealth neonatal intensive care unit (NICU) parent support smartphone application to improve psychosocial well-being, specifically reduced stress and anxiety, increased parenting competence, and improved social support among a diverse group of parents with infants born preterm in three Chicago-area NICUs.

Study Design: A time-lapsed, quasi-experimental design in which control participants were enrolled and then intervention participants enrolled. Data collection occurred at three timepoints: NICU admission (AD), discharge (DC), and 30 days post-discharge (DC+30).

Background: The current NCCN guidelines advocate for the use of adjuvant radiotherapy (RT) or chemoradiotherapy (CRT) in pT3N0 oral cavity squamous cell carcinoma (OCSCC). Here, we sought to evaluate whether postoperative RT/CRT may confer a survival advantage in pT3N0 patients who lack adverse pathological features.

Methods: A dataset of 852 pT3N0 OCSCC patients treated between 2018 and 2021 was analyzed.

There is substantial variation in access to transplantation across the United States that is not entirely explained by the availability of donor organs. Barriers to transplantation and variation in care among patients with end-stage organ disease exist prior to patients' placement on a transplant waiting list as well as following waitlist placement. However, there are currently no national data available to examine rates and variations in key care processes related to pre-listing, including transplant referral, evaluation, or candidate selection.

Background: Psoriasis is an inflammatory disease primarily treated through molecular-targeted therapies. However, emerging evidence suggests that dietary interventions may also play a role in managing inflammation associated with this condition. The Mediterranean diet (MedDiet), prevalent in southern European countries, has been widely recognized for its ability to reduce cardiovascular mortality, largely due to its anti-inflammatory properties.

J Med Chem

January 2025

Molecular Imaging Branch, National Institute of Mental Health, National Institutes of Health, Bethesda, Maryland, 20892 United States.

Article Synopsis
  • Gene therapy and cell transduction are emerging as promising treatments for neurological and psychiatric disorders, with PET imaging playing a key role in assessing treatment effectiveness.
  • The success of PET imaging relies on the creation of specific radiotracers that can identify exogenous transgenes or modified cells in the brain, potentially eliminating the need for invasive procedures.
  • This article discusses the current state and challenges in developing PET probes for monitoring gene therapy and cellular interventions, highlighting the importance of radiochemical development and practical applications in a clinical setting.
