Kifunensine-sensitive ADP-ribosylation factor A1EG69R mutant revealed coordination of protein glycosylation and vesicle transport pathways.

Complex N-glycans are asparagine (N)-linked branched sugar chains attached to secretory proteins in eukaryotes. They are produced by modification of N-linked oligosaccharide structures in the endoplasmic reticulum (ER) and Golgi apparatus. Complex N-glycans formed in the Golgi apparatus are often assigned specific roles unique to the host organism, with their roles in plants remaining largely unknown.

Shape Anisotropy-Dependent Leaking in Magnetic Neurons for Bio-Mimetic Neuromorphic Computing.

Spiking neural networks seek to emulate biological computation through interconnected artificial neuron and synapse devices. Spintronic neurons can leverage magnetization physics to mimic biological neuron functions, such as integration tied to magnetic domain wall (DW) propagation in a patterned nanotrack and firing tied to the resistance change of a magnetic tunnel junction (MTJ), captured in the domain wall-magnetic tunnel junction (DW-MTJ) device. Leaking, relaxation of a neuron when it is not under stimulation, is also predicted to be implemented based on DW drift as a DW relaxes to a low energy position, but it has not been well explored or demonstrated in device prototypes.

A computational study on the effect of structural isomerism on the excited state lifetime and redox energetics of archetype iridium photoredox catalyst platforms [Ir(ppy)2(bpy)]+ and Ir(ppy)3.

This study investigates the impact of structural isomerism on the excited state lifetime and redox energetics of heteroleptic [Ir(ppy)2(bpy)]+ and homoleptic Ir(ppy)3 photoredox catalysts using ground-state and time-dependent density functional theory methods. While the ground- and excited-state reduction potentials differ only slightly among the isomers of these complexes, our findings reveal significant variations in the radiative and non-radiative decay rates of the reactivity-controlling triplet 3MLCT states of these closely related species. The observed differences in radiative decay rates could be traced back to variations in the transition dipole moment, vertical energy gaps, and spin-orbit coupling of the isomers.

Impact of Non-Hepatectomy Opioid Reduction Efforts on Post-Hepatectomy Opioid Prescriptions: Analysis of 2,005 Patients.

Introduction: Pathway-driven, post-pancreatectomy opioid reduction interventions have proven effective and sustainable and may have a "halo effect" on other major abdominal cancer operations. This study's aim was to analyze the sequential effects of expanding opioid reduction efforts from pancreatectomy on opioids prescribed after hepatectomy.

Methods: This is a retrospective cohort study utilizing data from the electronic health record and a prospective quality improvement database for consecutive hepatectomy patients (09/2016-02/2024).

Impact of Massive Transfusion Activation on Time to Delivery of the First Cooler and Patient Survival: A Study of 4,313 Consecutive Activations.

Background: In 2012, TQIP guidelines for massive transfusion protocols (MTP) recommended delivery of blood product coolers within 15 minutes. Subsequent work found that every minute delay in cooler arrival was associated with a 5% increased risk of mortality. We sought to assess the impact and sustainability of quality improvement (QI) interventions on time to MTP cooler delivery and their association with trauma patient survival.

Breast Conservation Surgery for Breast Cancer in Men.

Background: Male breast cancer (MBC) is a rare disease, accounting for 1% of all breast cancers diagnosed in the United States. The rarity of MBC has limited the development of treatment algorithms specific to men. Thus, the standard of care has been mastectomy.

Circadian rhythm of heart rate and activity: A cross-sectional study.

Circadian rhythms are governed by a biological clock, and are known to occur in a variety of physiological processes. We report results on the circadian rhythm of heart rate observed using a wrist-worn wearable device (Fitbit), consisting of over 17,000 individuals over the course of 30 days. We obtain an underlying heart rate circadian rhythm from the time series heart rate by modeling the circadian rhythm as a sum over the first two Fourier harmonics.

Computational Tool for Determining Local Dielectric Constants in Heterogeneous Nanoscale Systems from Molecular Dynamics Trajectories.

In this work, we describe a computational tool designed to determine the local dielectric constants (ε) of charge-neutral heterogeneous systems by analyzing dipole moment fluctuations from molecular dynamics (MD) trajectories. Unlike conventional methods, our tool can calculate dielectric constants for dynamically evolving selections of molecules within a defined region of space, rather than for fixed sets of molecules. We validated our approach by computing the dielectric constants of TIP3P water nanospheres, achieving results consistent with literature values for bulk water.

Clinical criteria for limbic-predominant age-related TDP-43 encephalopathy.

Limbic predominant age-related TDP-43 encephalopathy neuropathologic change (LATE-NC) is highly prevalent in late life and a common co-pathology with Alzheimer's disease neuropathologic change (ADNC). LATE-NC is a slowly progressive, amnestic clinical syndrome. Alternatively, when present with ADNC, LATE-NC is associated with a more rapid course.

Pre-emptive treatment for cytomegalovirus viraemia to prevent cytomegalovirus disease in solid organ transplant recipients.

Background: Cytomegalovirus (CMV) is a significant cause of morbidity and death in solid organ transplant recipients. Pre-emptive treatment of patients with CMV viraemia using antiviral agents has been suggested as an alternative to routine prophylaxis to prevent CMV disease. This is an update of a Cochrane review first published in 2006 and updated in 2013.

A universal framework for design and manufacture of deterministic lateral displacement chips.

Despite being a high-resolution separation technique, deterministic lateral displacement (DLD) technology is facing multiple challenges with regard to design, manufacture, and operation of pertinent devices. This work specifically aims at alleviating difficulties associated with design and manufacture of DLD chips. The process of design and production of computer-aided design (CAD) mask layout files that are typically required for computational modeling analysis, optimization, as well as for manufacturing DLD-based micro/nanofluidic chips is complex, time-consuming, and often necessitates a high level of expertise in the field.

Glucose Transporter 1 Deficiency Impairs Glucose Metabolism and Barrier Induction in Human Induced Pluripotent Stem Cell-Derived Astrocytes.

Glucose is a major source of energy for the brain. At the blood-brain barrier (BBB), glucose uptake is facilitated by glucose transporter 1 (GLUT1). GLUT1 Deficiency Syndrome (GLUT1DS), a haploinsufficiency affecting SLC2A1, reduces glucose brain uptake.

Determinants of Racial and Ethnic Differences in Maternal Cardiovascular Health in Early Pregnancy.

Background: Suboptimal cardiovascular health (CVH) in pregnancy is associated with adverse maternal and offspring outcomes. To guide public health efforts to reduce disparities in maternal CVH, we determined the contribution of individual- and neighborhood-level factors to racial and ethnic differences in early pregnancy CVH.

Methods: We included nulliparous individuals with singleton pregnancies who self-identified as Hispanic, non-Hispanic Black (NHB), or non-Hispanic White (NHW) and participated in the nuMoM2b cohort study (Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be).

Percutaneous Mechanical Aspiration for Infective Endocarditis: Proceedings From an Inaugural Multidisciplinary Summit and Comprehensive Review.

The clinical presentation and epidemiology of infective endocarditis (IE) have evolved over time. While the cornerstones of IE treatment remain antimicrobial therapy and surgery, percutaneous mechanical aspiration (PMA) has emerged as an option for carefully selected patients as a complementary modality, based on retrospective data, case series, and expert experience. In this comprehensive review, we summarize the proceedings from an inaugural summit dedicated to the discussion of PMA in the global management of IE, consisting of experts across multiple disciplines from diverse geographic regions and care environments.

Supplementary motor area in speech initiation: A large-scale intracranial EEG evaluation of stereotyped word articulation.

Speech production engages a distributed network of cortical and subcortical brain regions. The supplementary motor area (SMA) has long been thought to be a key hub in coordinating across these regions to initiate voluntary movements, including speech. We analyzed direct intracranial recordings from 115 patients with epilepsy as they articulated a single word in a subset of trials from a picture-naming task.

One-Year Outcomes in Subjects Developing Macular Neovascularization While Undergoing Avacincaptad Pegol Therapy for Geographic Atrophy.

Purpose: To assess the 12-month outcomes in subjects developing macular neovascularization (MNV) during intravitreal avacincaptad pegol (IVA) treatment for geographic atrophy (GA) secondary to age-related macular degeneration (AMD).

Methods: This research was conducted as a case-controlled, retrospective study of AMD subjects undergoing IVA treatment for GA from two private practice institutions. Subjects were divided into 1) a Study Group of patients who developed MNV and then underwent anti-vascular endothelial growth factor (VEGF) therapy during the study period, and 2) a Control Group of patients who were complication-free during the study period.

Organelle-Targeting Nanoparticles.

Organelles are specialized subunits within cells which carry out vital functions crucial to cellular survival and form a tightly regulated network. Dysfunctions in any of these organelles are linked to numerous diseases impacting virtually every organ system in the human body. Targeted delivery of therapeutics to specific organelles within the cell holds great promise for overcoming challenging diseases and improving treatment outcomes through the minimization of therapeutic dosage and off-target effects.

Management of Acute Coronary Syndrome in Patients With Transcatheter Aortic Valve Replacement: A Review.

Transcatheter aortic valve replacement (TAVR) has become a viable treatment option for patients with severe aortic stenosis among all risk subsets. As TAVR use becomes more prevalent and patients live longer with their transcatheter valve, an increasing number of these patients can be expected to present with ACS. Overall, there is a paucity of high-quality data detailing incidence, pathophysiology, and management of ACS in this subset.

Tissue-Engineered Therapeutics for Lymphatic Regeneration: Solutions for Myocardial Infarction and Secondary Lymphedema.

The lymphatic system, which regulates inflammation and fluid homeostasis, is damaged in various diseases including myocardial infarction (MI) and breast-cancer-related lymphedema (BCRL). Mounting evidence suggests that restoring tissue fluid drainage and clearing excess immune cells by regenerating damaged lymphatic vessels can aid in cardiac repair and lymphedema amelioration. Current treatments primarily address symptoms rather than underlying causes due to a lack of regenerative therapies, highlighting the importance of the lymphatic system as a promising novel therapeutic target.

Meta-analysis of longitudinal comparison of transcatheter versus surgical aortic valve replacement in patients at low to intermediate surgical risk.

Background: Surgical aortic valve replacement (SAVR) is the commonly used approach for aortic valve replacement (AVR) in patients with aortic stenosis at low or intermediate surgical risk. However, transcatheter aortic valve replacement (TAVR) has emerged as an alternative to SAVR for AVR. This meta-analysis aims to assess the comparative efficacy and safety of TAVR versus SAVR in low-to-intermediate surgical risk patients by analyzing temporal trends in the outcomes of TAVR and SAVR at various follow-up intervals, providing a more detailed understanding.
