Laser Interstitial Thermal Therapy for Brain Tumors: A Prospective Multicenter Analysis of Patients From the LAANTERN Study

Background: Laser interstitial thermal therapy is a surgical tool used to ablate brain tumors, radiation necrosis, and epileptic foci. Data from the completed LAANTERN prospective multicenter registry (NCT02392078), containing tumor patients enrolled in the study across 25 US cen...

Management Patterns and Outcomes of Vestibular Schwannoma in Older Adults: Assessment of the SEER Database

OBJECTIVE: Vestibular schwannoma (VS) is a benign intracranial tumor that is increasingly diagnosed in older adults. The relative contributions of tumor burden and surgical management to overall survival in elderly and very elderly patients remain incompletely characterized at a...

A Review ofAmmonia (NH3) Adsorption inPorous Solids

Abstract Ammonia (NH3) plays a crucial role in the agricultural sector as a fertilizer and is a dense hydrogen carrier that offers a potential renewable and carbon-free energy source. These significant advantages necessitate the development of efficient NH3 synthesis and separati...

Pharmacokinetic and pharmacodynamic sub-study of trans-arterial vs. intravenous gemcitabine in the TIGeR-PaC phase 3 clinical trial

Abstract Purpose Localized intra-arterial delivery of gemcitabine (IAG) may provide advantages in terms of increased tissue concentration and decreased systemic dosing. We hypothesized IAG may result in decreased systemic gemcitabine concentration and associated side effects due...

Insulin-Regulated Actin Dynamics is Disrupted in a Human Keratinocyte Model of Hailey Hailey Disease

Abstract Hailey Hailey Disease (HHD) is an autosomal dominant cutaneous disorder caused by mutations in ATP2C1 , the gene encoding the Golgi/secretory pathway Ca 2+ -ATPase SPCA1. Characterized by suprabasal acantholysis and intertriginous blistering of the skin, HHD treatment fo...

Study protocol for first national vasa previa perinatal registry

Vasa previa is a rare but potentially catastrophic obstetric condition characterized by unprotected fetal blood vessels over or adjacent to the internal cervical os. Although advances in prenatal ultrasound have dramatically improved neonatal survival through planned cesarean del...

A Head-to-Head Comparison of Three Literature Algorithms for Physical Activity Endpoints from a Wrist Accelerometer in Free-Living Conditions

Wrist accelerometers are widely used in clinical trials for continuous assessment of participants’ day-to-day physical activity and function, through derivation of metrics such as time spent in sedentary, non-sedentary, light, and moderate-to-vigorous physical activity (MVPA). Mu...

Characterizing intra- and intertumor heterogeneity in ovarian high-grade serous carcinoma subtypes using single-cell and spatial transcriptomics

Ovarian high-grade serous carcinoma (HGSC) is an aggressive ovarian cancer with a heterogeneous tumor microenvironment (TME). Advances in single-cell RNA sequencing (scRNA-seq) and spatially-resolved transcriptomics have enabled the study of complex TME. This study explores conne...

Development of a Tool to Assess Competency in Bronchoscopic Lung Volume Reduction Via Endobronchial Valve Placement

RATIONALE: Bronchoscopic lung volume reduction (BLVR) is an established treatment option for severe emphysema, improving lung function and quality of life. Despite its growing use, there are no standardized, validated tools to assess operator competency in performing BLVR, limiti...

Functional Activity of TDP-43: A Direct Biomarker for ALS

TDP-43 dysfunction is a defining feature of amyotrophic lateral sclerosis (ALS), yet no biofluid biomarker directly measures its functional activity. We developed a serum-based homogeneous time-resolved FRET (hTR-FRET) assay that quantifies TDP-43 RNA binding activity using synth...

Towards unified AI-driven fracture mechanics: the extended deep energy method (XDEM)

Abstract Physics-Informed Neural Networks (PINNs) have recently emerged as powerful tools for solving partial differential equations (PDEs), with the Deep Energy Method (DEM) proving especially effective in fracture mechanics due to its energy-based formulation. Despite these adv...

The hematology workforce in the United States: past, present, and strategies for the future

From 2017-2021, the American Society of Hematology (ASH) completed the largest study ever conducted of the hematology workforce in the United States (US). The study highlighted a deficit in the classical hematology (CH) workforce: despite very high CH clinical volumes encountered...

ARport: an augmented reality system for markerless image-guided port placement in robotic surgery

Abstract Purpose Precise port placement is a critical step in robot-assisted surgery, where port configuration influences both visual access to the operative field and instrument maneuverability. To bridge the gap between preoperative planning and intraoperative execution, we pre...

Association Between Changes in Perceived Neighborhood and Cognitive Performance Within Healthy Aging in Neighborhoods of Diversity Across the Life Span (HANDLS) Black Adults

Perceived neighborhood characteristics are related to cognitive performance. However, limited studies have examined how changes in neighborhood characteristics relate to cognitive performance, particularly among Black adults who are likely to experience changes in their residenti...

Vision-Language Model as a ‘Zero-Shot’ Assistant for Evaluating Condylar Osseous Changes in Cone-beam Computed Tomography

INTRODUCTION AND AIMS: Interpreting condylar osseous changes on CBCT is challenging for general practitioners. This study evaluated the 'zero-shot' diagnostic performance and utility of Vision-Language Models (VLMs) as AI assistants for detecting condylar abnormalities. METHODS:...

Lipid-Rich Urothelial Carcinoma

Lipid-rich urothelial carcinoma (LR-UC) is a rare subtype, with ∼65 cases reported in the literature. Here, we report the largest case series of bladder LR-UC, including 40 patients. Clinical follow-up was available for 29 patients. Twenty-seven patients had at least 2-years foll...

Acceptability and Feasibility of a Primary Care Hypoglycemia Prevention Program: A Pilot Study

OBJECTIVE Hypoglycemia, a major cause of morbidity for people with diabetes, is underrecognized in primary care, leading to underuse of risk mitigation strategies. This study reports the development and acceptability/feasibility testing of the Hypoglycemia Prevention Program (HPP...

The Shadow of Your Law and the Judge Over Your Shoulder

ABSTRACT Many problems in public policy and delivery which are otherwise difficult to understand, make much more sense when viewed as strategies for the management of legal risk. Civil servants, infrastructure developers and other parties who are subject to the risk of legal revi...

The extreme diversity of retinal amacrine cells has deep evolutionary roots

Amacrine cells (ACs) comprise a heterogeneous class of inhibitory neurons in the vertebrate retina, exhibiting morphological and functional complexity rivaling that of cortical interneurons. Here, we integrate single-cell and single-nucleus transcriptomic atlases from 24 vertebra...

Nucleosomes and IDRs suppress promiscuous GCN4 binding on minichromosomes

Abstract Eukaryotic sequence-specific transcription factors (TFs) must find their cognate DNA targets hidden in genomic chromatin amid an excess of nonspecific sequences and degenerate motifs. Although static TF interactions with nucleosomal targets have been elucidated, how TFs...
