Diffuse axonal injury (DAI) is caused by acceleration-deceleration forces during trauma that shear white matter tracts. Susceptibility-weighted MRI (SWI) identifies microbleeds that are considered the radiologic hallmark of DAI and are used in clinical prognostication. However, this assumption is limited by a lack of systematic radiologic-pathologic correlation studies. Here, we performed ex vivo SWI on three brains from patients who died after severe TBI and assessed axonal injury around SWI...

In human skin, erythema assessed 24 h after ultraviolet (UV) exposure is a non-invasive method for determining the acute UV response. Although erythema is often reported in murine models as a measure of acute UV response, the most informative timepoint after UV exposure is unclear because of variability in mouse strain, sex, and light source. Our current work addresses this critical gap by elucidating the development of erythema and edema over time after acute UV irradiation with solar-simulator...

The physiological properties of human and rodent neurons differ, yet the extent to which these differences reflect human specializations is often unclear. Compared with their rodent counterparts, human supragranular pyramidal neurons possess enriched Hyperpolarization-activated Cyclic Nucleotide-gated channel (HCN channel)-dependent intrinsic membrane properties and a related sensitivity to synaptic inputs containing delta/theta band frequencies. Here we test whether other primate species...

CONCLUSION: Male and female patients demonstrated comparable improvements in PROs, achievement of clinically meaningful thresholds, revision rates, and rates of conversion to total hip arthroplasty after hip arthroscopy. Although men exhibited larger alpha angles and more advanced chondral damage, and women more frequently underwent capsular repair, these sex-based differences did not translate into clinically significant disparities in postoperative outcomes.

CONCLUSIONS: Primary care OUD treatment rates varied markedly. Exemplar clinics in which all primary care providers were expected to treat OUD had the highest treatment rates at baseline and follow-up, suggesting that universal prescribing is a promising approach to increasing OUD treatment in primary care.

CONCLUSIONS: Our study did not demonstrate differences in shunt survival between children <6 months of age requiring cerebrospinal fluid diversion secondary to PHH who had NEC and those who did not. Thus, peritoneal shunt placement may be suitable for children with NEC despite having abdominal interventions.

The human neocortex underlies higher cognition and is the engine of complex thought. Yet our understanding of its neuronal diversity is limited by sparse access to tissue, inconsistent sampling across studies, and a lack of multiple modality data. Although single-cell transcriptomic taxonomies are an important framework for characterizing cell type diversity, transcriptomic information alone cannot reveal the cellular properties that define neuronal computations. To address this, we performed...

BACKGROUND: Before infecting red blood cells and causing the clinical manifestations of malaria, the hepatotropic parasite Plasmodium falciparum completes a complex liver stage. Sex-based differences in pathogenesis by hepatotropic micro-organisms are well documented but unstudied for P falciparum in humans. We aimed to evaluate the effect of sex on the time to blood-stage positivity and initial blood-stage parasite densities as indicators of liver-stage dynamics and parasite replication.

Correction for 'HunStat2 - a simple and low-cost potentiostat with electrochemical impedance spectroscopy capability' by Istvan Vamos et al., Anal. Methods, 2025, 17, 9494-9499, https://doi.org/10.1039/D5AY01179E.

Follicular lymphoma (FL) patients have variable outcomes, underscoring the need for biomarkers for improved risk stratification. Current FL grading systems, based on subjective centroblast counts, suffer from poor reproducibility, despite evidence linking grade 3 FL to worse prognosis. We aimed to identify objective biomarkers for centroblasts and centrocytes to improve FL prognostication. We reanalyzed publicly available spatial and single-cell transcriptomic data from normal germinal centers...

Background/Objectives: To evaluate risk factors for postoperative neurological deficits following cervical endoscopic unilateral laminotomy for bilateral decompression (CE-ULBD) and to determine whether intraoperative neurophysiological monitoring (IONM) can predict neurological compromise. Methods: A multicenter retrospective review was performed on 42 CE-ULBD procedures conducted between 2016 and 2024; 33 cases met the inclusion criteria with available imaging and electromyography data....

Adenosine-to-inosine (A-to-I) RNA editing by ADAR enzymes shapes transcript fate and underpins emerging RNA editing therapeutics, yet predicting which adenosines are edited remains difficult. We introduce ADAR-GPT, a model-agnostic fine-tuning framework that adapts a GPT-class language model to classify editing at candidate sites using sequence context in standardized 201 nt windows with the target adenosine explicitly marked. We train and evaluate on GTEx liver data ([Formula: see text]...

Treatment resistance remains a formidable barrier to curing lymphomas, driven in part by their ability to alter their phenotypic and molecular profiles under therapeutic pressure. A growing body of evidence suggests that a clinically minute population of drug-tolerant persister (DTP) cells, which undergo non-genetic adaptations to survive therapy, are responsible for seeding relapse. We highlight the substantial progress being made to characterize DTP populations, and postulate that they confer...

Creatine (CR) is essential for normal brain function. A lack of brain CR results in intellectual disability, epilepsy, and language delay in humans. The most common cause of CR deficiency in humans results from mutations in the CR transporter (SLC6A8). Several large deletion models of Slc6a8 have been characterized and are excellent models for global creatine loss. However, other SLC6A8 variants are reported in humans with creatine transporter deficiency (CTD), including missense mutations,...

While most meningiomas are benign and can be surgically removed, a subset behaves aggressively, recurs quickly, and can ultimately be fatal. Recent work has focused on defining this aggressive group. To better characterize this clinically distinct, high-risk group, we analyzed bulk RNA sequencing (RNA-seq) from human meningiomas using a dimension-reduced reference landscape. We identified an NF2 mutant subtype enriched for chromosome 10q loss and low PTEN expression, both of which were strongly...
