Conventionally, the size, shape, and biomechanics of cartilages are determined by their voluminous extracellular matrix. By contrast, we found that multiple murine cartilages consist of lipid-filled cells called lipochondrocytes. Despite resembling adipocytes, lipochondrocytes were molecularly distinct and produced lipids exclusively through de novo lipogenesis.

Examining the risk of delirium in patients hospitalized with COVID-19: Insights from the homeless population.

PLoS One

January 2025

Department of Diagnostic and Health Sciences, College of Health Professions, University of Tennessee Health Science Center, Memphis, TN, United States of America.

For patients hospitalized with COVID-19, delirium is a serious and under-recognized complication, and people experiencing homelessness (PEH) may be at greater risk. This retrospective cohort study compared delirium-associated risk factors and clinical outcomes between PEH and non-PEH. This study used patient records from 154 hospitals discharged from 2020-2021 from the Texas Inpatient Public Use Data file.

Introduction: Measurement of repeatability and reproducibility (R&R) is necessary to realize the full potential of positron emission tomography (PET). Several studies have evaluated the reproducibility of PET using 18F-FDG, the most common PET tracer used in oncology, but similar studies using other PET tracers are scarce. Even fewer assess agreement and R&R with statistical methods designed explicitly for the task.

Introduction: Those with established symptomatic cardiopulmonary disease should attend secondary prevention programs. Attendance at these programs is known to differ by sex and by smoking status, with females and those who smoke being less likely to attend. However, little is known about whether the risk factors of being female and smoking are cumulative, and how outcomes from secondary prevention differ by these subgroups.

Health Professions Education (HPE) assessment is being increasingly impacted by Artificial Intelligence (AI), and institutions, educators, and learners are grappling with AI's ever-evolving complexities, dangers, and potential. This AMEE Guide aims to assist all HPE stakeholders by helping them navigate the assessment uncertainty before them. Although the impetus is AI, the Guide grounds its path in pedagogical theory, considers the range of human responses, and then deals with assessment types, challenges, AI roles as tutor and learner, and required competencies.

tRNA modifications are critical for several aspects of their functions, including decoding, folding, and stability. Using a multifaceted approach encompassing eCLIP-seq and nanopore tRNA-seq, we show that the human tRNA methyltransferase TRMT1L interacts with the component of the Rix1 ribosome biogenesis complex and binds to the 28S rRNA as well as to a subset of tRNAs. Mechanistically, we demonstrate that TRMT1L is responsible for catalyzing N2,N2-dimethylguanosine (mG) solely at position 27 of tRNA-Tyr-GUA.

Historically the physiological or pathological loss of tooth structure in situ was deemed to be due to the 'absorption' of tooth structure due to the removal of the inorganic components of dentin and cementum by osteoclastic (dentinoclastic) cellular activity. This nomenclature and the activity that it represented was considered by almost all dental researchers and clinicians in the 1800s and early 1900s. The shift to the concept of 'resorption' occurred in the first half of the 20th century, with clarity emanating from significant research activity on the pathology of osseous structures, origin of osteoclastic cell types, and the function of periodontal ligament cells.

A unique type of advertising trade card was popular in Europe, mostly Belgium, between 1840 and 1865. These cards were produced with a coating of a white lead substance that gave them a lustrous appearance and feel, resembling porcelain. As attractive as these cards were, producing them oftentimes resulted in lead poisoning for the printers, so few were produced after 1865.

Nonapoptotic role of EGL-1 in exopher production and neuronal health in .

Proc Natl Acad Sci U S A

January 2025

Department of Neuroscience, Center for Learning and Memory, Waggoner Center for Alcohol & Addiction Research, University of Texas at Austin, Austin, TX 78712.

While traditionally studied for their proapoptotic functions in activating the caspase, research suggests BH3-only proteins also have other roles such as mitochondrial dynamics regulation. Here, we find that EGL-1, the BH3-only protein in , promotes the cell-autonomous production of exophers in adult neurons. Exophers are large, micron-scale vesicles that are ejected from the cell and contain cellular components such as mitochondria.

The effects of T cell differentiation arising from immune checkpoint inhibition targeting cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) and programmed cell death protein 1 (PD-1) on the immunological memory response remain unclear. Our investigation into the effects of anti-CTLA-4 and anti-PD-1 on memory T cell formation in mice reveals that memory T cells generated by anti-CTLA-4 exhibit greater expansion, cytokine production, and antitumor activity than those from anti-PD-1. Notably, anti-CTLA-4 preserves more T cell factor-1 (TCF-1)+ T cells during priming, while anti-PD-1 leads to more thymocyte selection-associated high mobility group box (TOX)+ T cells.

Unidirectional and bidirectional causation between smoking and blood DNA methylation: evidence from twin-based Mendelian randomisation.

Eur J Epidemiol

January 2025

Department of Psychiatry, Virginia Institute for Psychiatric and Behavioral Genetics, Virginia Commonwealth University, 800 E. Leigh St., Suite 100, Richmond, VA, 23298, USA.

Cigarette smoking is associated with numerous differentially-methylated genomic loci in multiple human tissues. These associations are often assumed to reflect the causal effects of smoking on DNA methylation (DNAm), which may underpin some of the adverse health sequelae of smoking. However, prior causal analyses with Mendelian Randomisation (MR) have found limited support for such effects.

Department of Psychiatry and Behavioral Health, Stony Brook University, 101 Nicolls Road, Stony Brook, NY, USA.

The diagnosis of bipolar disorder (BD) in young children has been a topic of debate, in part owing to varied interpretation of manic-like symptoms. We examined how expert academic clinicians participating in the pediatric bipolar biobank varied in their interpretation and application of Diagnostic and Statistical Manual of Mental Disorders (DSM) criteria and diagnoses. Study co-investigators reviewed 12 standardized narratives and for each marked a visual analog scale with their confidence in the presence of manic episodes and criteria.

Purpose: Studies of healthcare encounters leading to cancer diagnosis have increased over recent years. While some studies examine healthcare utilization before the cancer registry date of diagnosis, relevant pre-diagnosis interactions are not always immediately prior to this date due to date abstraction guidelines. We evaluated agreement of a registry date with a claims-based index and examined Emergency Department (ED) involvement in cancer diagnosis as an example of possible pre-diagnostic healthcare misclassification that could arise from improper date choice.
