Machine Learning Mapping Approach for Computing Spin Relaxation Dynamics.

In this work, a machine learning mapping approach for predicting the properties of atomistic systems is reported. Within this approach, the atomic orbital overlap, density, or Kohn-Sham (KS) Fock matrix elements obtained at a low level of theory such as extended tight-binding have been used as input features to predict the electric field gradient (EFG) tensors at a higher level of theory such as those obtained with hybrid functionals. It is shown that the machine-learning-predicted EFG tensors can be used to compute spin relaxation rates of several ions in aqueous solutions.

De-escalating and discontinuing disease-modifying therapies in multiple sclerosis.

The development of disease-modifying therapies (DMTs) for the treatment of multiple sclerosis (MS) has been highly successful in recent decades. It is now widely accepted that early initiation of DMTs after disease onset is associated with a better long-term prognosis. However, the question of when and how to de-escalate or discontinue DMTs remains open and critical.

A New Perspective on Drugs for Duchenne Muscular Dystrophy: Proposals for Better Respiratory Outcomes and Improved Regulatory Pathways.

New drugs for Duchenne muscular dystrophy (DMD) are emerging rapidly. However, we and others believe these drugs are achieving regulatory approval prematurely. It is the cardiorespiratory complications of DMD that cause the disease's major morbidities and that determine survival.

The association of statin therapy with reduced intracranial aneurysm recurrence after endovascular coiling: a post hoc propensity score-matched analysis of a randomized clinical trial.

Objective: Endovascular intracranial aneurysm (IA) management has significantly evolved over the last 2 decades. Despite these advancements, the aneurysm recanalization rate after coil embolization remains a concern. Statins have been found to affect vascular repair and remodeling; therefore, the authors hypothesized that patients receiving statin therapy at the time of coil embolization would have lower aneurysm recurrence and retreatment rates compared with patients not receiving statin therapy.

What Happens When Undergraduate Biology Students Meet with Professional Scientists to Discuss Research? An Exploratory Investigation into Scientific Discourse, Motivation, and Sense of Belonging.

Engagement in scientific discourse is an essential part of becoming a scientist. In this exploratory study, we aim to examine the scientific discourse (and resulting benefits) between undergraduate biology students and professional scientists. We developed a novel method for engaging in scientific discourse, grounded in the theory of legitimate peripheral participation, where undergraduate biology students participate in communities of practice within their own departments.

Self-Transcendence as a Risk and Resilience Factor in Individuals at Clinical High Risk for Psychosis.

Aim: Self-transcendence is a personality feature and psychological resource that involves feelings of connectedness with the universe, all of humanity, and the individual self. Self-transcendence has been positively associated with both positive psychotic symptoms and clinical high risk for developing psychosis status, but studies reporting these findings focus solely on the connectedness-with-universe aspect of self-transcendence. The broader self-transcendence literature, which also includes connection with humanity and oneself, robustly supports self-transcendence as an indicator of well-being.

Fiat Surfaces in the Basic Formal Ontology.

The Basic Formal Ontology (BFO) class and its subclasses, including , are not heavily axiomatized; they have elucidations, not definitions; and the meanings of these elucidations are poorly captured by the relevant BFO axioms. This paper is an effort to make progress in these respects for . We identify a range of desiderata for a BFO-conformant view of , argue that the GitHub does not satisfy them, argue that the view of fiat surfaces in Arp et al.

CHEF: A Framework for Deploying Heterogeneous Models on Clusters with Heterogeneous FPGAs.

DNNs are rapidly evolving from streamlined single-modality single-task (SMST) to multi-modality multi-task (MMMT) with large variations for different layers and complex data dependencies among layers. To support such models, hardware systems also evolved to be heterogeneous. The heterogeneous system comes from the prevailing trend to integrate diverse accelerators into the system for lower latency.

Cell- and tissue-specific glycosylation pathways informed by single-cell transcriptomics.

While single-cell studies have made significant impacts in various subfields of biology, they lag in the Glycosciences. To address this gap, we analyzed single-cell glycogene expressions in the Tabula Sapiens dataset of human tissues and cell types using a recent glycosylation-specific gene ontology (GlycoEnzOnto). At the median sequencing (count) depth, ∼40-50 out of 400 glycogenes were detected in individual cells.

Cytokine profiling reveals HLA-linked Th2 and Th17 driven immune activation in pemphigus vulgaris patients and genetically susceptible healthy controls.

Introduction: Cytokines and chemokines direct the inflammatory response and may serve as markers of immune dysregulation in Pemphigus vulgaris (PV), an autoimmune blistering skin disorder. Previous studies on limited numbers of patients and cytokine profiles in PV have produced equivocal results regarding the role these mediators play in disease.

Methods: In this study, we interrogated serum samples from 116 PV patients and 29 healthy controls by multiplexed bead array assays across a comprehensive set of cytokines and chemokines covering several functional categories, including IL-1α, IL-1β, IL-2, IL-4, IL-5, IL-6, IL-8, IL-9, IL-10, IL-12, IL-13, IL-15, IL-17, IL-21, IL-22, IL-23, TNFα, IFNγ, MCP-1, and Eotaxin.

Updates in novel immunotherapeutic strategies for relapsed/refractory AML.

Acute myeloid leukemia (AML) is a severe hematological malignancy with poor outcomes, particularly in older adults. Traditional treatment options like high-dose chemotherapy often lead to refractory or relapsed AML, with even worse outcomes. New therapies for relapsed and refractory AML are needed, and this review explores the most recent advancements in immunotherapy in AML.

A Painful Reality Check? Examining the Accuracy of Subjective Survival Probabilities by Pain Interference and Depression Status.

Purpose: Pain and depression are linked to higher mortality risk and lower subjective survival probabilities (SSPs). We examine if SSPs for individuals with pain and depression match their actual lifespans.

Methods: Using data on 12,745 Health and Retirement Study respondents aged 57-89 in 2000 with follow-up through 2018, we assessed whether respondents' SSPs were "correct," "underestimated," or "overestimated" relative to their lifespans.

Translational PK-PD model for in vivo CAR-T-cell therapy delivered using CAR mRNA-loaded polymeric nanoparticle vector.

Autologous chimeric antigen receptor (CAR) T-cell therapy has demonstrated remarkable response rates, yet its widespread implementation is hindered by logistical, financial, and physical constraints. Additionally, challenges such as poor persistence and allorejection are associated with allogeneic cell therapies. An innovative approach involves in vivo transduction of endogenous T-cells through the administration of CAR mRNA encapsulated in polymeric nanoparticles (NPs), resulting in transient CAR surface expression on circulating T-cells.

Collaborative design of a care pathway for pharmacy-based PrEP delivery in Nigeria: insights from stakeholder consultation.

Background: HIV remains a significant public health problem, particularly in Africa, where two-thirds of global cases occur. Nigeria is among the three countries with the highest burden. Despite free access to pre- and post-exposure prophylaxis (PrEP and PEP) in Nigerian hospitals, stigma, distance, and restrictive clinic hours hinder uptake, especially among vulnerable populations.

Differential cardiac impacts of hematological malignancies and solid tumors: a histopathological and biomarker study.

Background: Cancer patients are known to be associated with increased risk of cardiovascular disease. However, no studies have examined the differential impact of hematologic malignancies (HMs) and solid tumors (STs) on cardiac morphology at the tissue level.

Objective: We aimed to examine histopathological features alongside cardiovascular biomarkers in patients with HMs and STs who underwent post-mortem evaluation.

Late Glacial summer paleohydrology across Central Europe.

It is generally accepted that a weakening of the North Atlantic thermohaline circulation caused the Younger Dryas cooling. Although the role of seasonality was emphasized previously, this aspect is rarely considered yet, and it remains elusive how this impacted hydroclimate during winters and summers across Central Europe. Here, we coupled biomarker-based δO and δH from Bergsee in southern Germany to reconstruct deuterium excess as a proxy for evaporation history from the Bølling-Allerød to the Preboreal.

Computer Modeling of Bevacizumab Drug Distribution After Intravitreal Injection in Rabbit and Human Eyes.

Age-related macular degeneration (AMD) is a progressive eye disease that causes loss of central vision and has no cure. Wet AMD is the late neovascular form treated with vascular endothelial growth factor (VEGF) inhibitors. VEGF is the critical driver of wet AMD.

Parallel mechanical computing: Metamaterials that can multitask.

Decades after being replaced with digital platforms, analogue computing has experienced a surging interest following developments in metamaterials and intricate fabrication techniques. Specifically, wave-based analogue computers which impart spatial transformations on an incident wavefront, commensurate with a desired mathematical operation, have gained traction owing to their ability to directly encode the input in its unprocessed form, bypassing analogue-to-digital conversion. While promising, these systems are inherently limited to single-task configurations.

Conformational dynamics of a nicotinic receptor neurotransmitter site.

Agonists enhance receptor activity by providing net-favorable binding energy to active over resting conformations, with efficiency (η) linking binding energy to gating. Previously, we showed that in nicotinic receptors, η-values are grouped into five structural pairs, correlating efficacy and affinity within each class, uniting binding with allosteric activation (Indurthi and Auerbach, 2023). Here, we use molecular dynamics (MD) simulations to investigate the low-to-high affinity transition (L→H) at the Torpedo α-δ nicotinic acetylcholine receptor neurotransmitter site.
