Article Synopsis
  • High-mobility group box-1 (HMGB1) levels rise and undergo post-translational modifications (PTMs) with alcohol consumption, potentially influencing the development of alcohol-associated liver disease (AALD).
  • Researchers used a specific model of liver injury caused by alcohol to explore how manipulating HMGB1's expression and modifications in liver cells and immune cells impacts AALD.
  • Their findings show that different forms of HMGB1 have contrasting effects: oxidized HMGB1 (O) worsens liver injury while acetylated HMGB1 (Ac) can protect against these harmful effects, highlighting the importance of targeting O HMGB1 in treating AALD.

Mono(ADP-ribosyl)ation (MARylation) is emerging as a critical regulator of ribosome function and translation. Herein, we demonstrate that RACK1, an integral component of the ribosome, is MARylated by the mono(ADP-ribosyl) transferase (MART) PARP14 in ovarian cancer cells. MARylation of RACK1 is required for stress granule formation and promotes the colocalization of RACK1 in stress granules with G3BP1, eIF3η, and 40S ribosomal proteins.

Inhibition of proteolytic and ATPase activities of the proteasome by the BTK inhibitor CGI-1746.

iScience

November 2024

Department of Drug Discovery and Development, Harrison College of Pharmacy, Auburn University, 720 S. Donahue Dr., Auburn, AL, USA.

Bruton's tyrosine kinase (BTK) inhibitor, ibrutinib, has been shown to synergize with proteasome inhibitors (PIs) in reducing the viability of cells derived from B cell malignancies, but the mechanism is not known. We report here that an off-target effect of ibrutinib causes synergy because not all BTK inhibitors exhibited the synergistic effect, and those that synergized did so even in cells that do not express BTK. The allosteric BTK inhibitor CGI-1746 showed the strongest synergy.

Electroencephalography is instrumental in understanding neurophysiological mechanisms underlying working memory. While numerous studies have associated electroencephalography features to working memory, understanding causal relationships leads to better characterization of the neurophysiological mechanisms that are directly linked to working memory. Personalized causal modeling is a tool to discover these direct links between brain features and working memory performance.

Article Synopsis
  • Disturbances in kidney tubular cell metabolism are significant in acute kidney injury (AKI), particularly affecting NAD metabolism.
  • Recent studies show that these metabolic shifts during AKI can lead to lasting changes, increasing the risk of developing chronic kidney disease (CKD).
  • The review discusses the molecular mechanisms of this metabolic dysfunction in AKI and suggests how these acute changes in NAD metabolism can have long-term impacts on kidney health.

This article updates the prior 2018 consensus statement by the National Network of Depression Centers (NNDC) on the use of transcranial magnetic stimulation (TMS) in the treatment of depression, incorporating recent research and clinical developments. Publications on TMS and depression between September 2016 and April 2024 were identified using methods informed by PRISMA guidelines. The NNDC Neuromodulation Work Group met monthly between October 2022 and April 2024 to define important clinical topics and review pertinent literature.

Background: Improving patient education has been shown to improve clinical outcomes and reduce disparities, though such efforts can be labor intensive. Large language models may serve as an accessible method to improve patient educational material. The aim of this study was to compare readability between existing educational materials and those generated by large language models.

Salient Voice Symptoms in Primary Muscle Tension Dysphonia.

J Voice

January 2025

School of Behavioral and Brain Sciences, Department of Speech, Language, and Hearing, Callier Center for Communication Disorders, University of Texas at Dallas, Richardson, TX; Department of Otolaryngology - Head and Neck Surgery, University of Texas Southwestern Medical Center, Dallas, TX. Electronic address:

Introduction: Patients with primary muscle tension dysphonia (pMTD) commonly report symptoms of vocal effort, fatigue, discomfort, odynophonia, and aberrant vocal quality (eg, vocal strain, hoarseness). However, voice symptoms most salient to pMTD have not been identified. Furthermore, how standard vocal fatigue and vocal tract discomfort indices that capture persistent symptoms-like the Vocal Fatigue Index (VFI) and Vocal Tract Discomfort Scale (VTDS)-relate to acute symptoms experienced at the time of the voice evaluation is unclear.

Background: Rhinoconjunctivitis phenotypes are conventionally described on the basis of symptom severity, duration and seasonality, and aeroallergen sensitization. It is not known whether these phenotypes fully reflect the patterns of symptoms seen at a population level.

Objective: We sought to identify phenotypes of rhinoconjunctivitis on the basis of symptom intensity and seasonality using an unbiased approach and to compare their characteristics.

A Guide to Pediatric Antibiotic Allergy Testing: A Report From the US Drug Allergy Registry.

J Allergy Clin Immunol Pract

January 2025

Division of Rheumatology, Allergy, and Immunology, Department of Medicine, Massachusetts General Hospital, Boston, Mass; Department of Medicine, Harvard Medical School, Boston, Mass.

Pediatric antibiotic labels are common, and unnecessary antibiotic avoidance is associated with negative personal and public health outcomes; as a result, there is an increasing emphasis on the importance of pediatric antibiotic allergy evaluations. Different testing strategies have been advised, including skin testing and challenge testing with varied doses and duration. Established consensus testing protocols are lacking.

Rearrangements of cytokine receptor-like factor 2 gene (CRLF2) are present in ∼50% of B-lymphoblastic leukemia/lymphoma (B-ALL) with BCR::ABL1-like features. Herein, we report three patients with CRLF2-rearranged mixed phenotype acute leukemia (MPAL). All three cases were B/myeloid MPAL in young patients harboring P2RY8::CRLF2 or IGH::CRLF2 with additional genomic alterations in signaling (JAK and RAS) and cell cycle (CDKN2A/B) pathways, a genomic profile similar to that in BCR::ABL1-like B-ALL.

Article Synopsis
  • This study analyzes prognostic factors affecting long-term outcomes and changes in contusion volume in patients with traumatic brain injuries (TBI) due to hemorrhagic cerebral contusions.
  • Key findings indicate that older age, larger initial contusion volumes, and lower Glasgow Coma Scale (GCS) scores are linked to worse functional outcomes post-injury.
  • The research suggests that the GCS verbal score could predict both initial contusion volume and potential expansion, highlighting its importance in managing and predicting patient outcomes in neurosurgery.

The term autoinflammatory keratinization diseases (AIKDs) was recently proposed as a unifying concept for diseases characterized by inflammation in the epidermis and upper dermis which leads to hyperkeratosis, caused by genetic perturbations of the innate immune system. We present a case of a patient with hidradenitis suppurativa and porokeratosis, two AIKDs, followed by a review of these conditions as well as other AIKDs. This case was distinguished by hypertrophic porokeratoses involving cystic hair follicles, showing histopathologic features of both conditions within single biopsy specimens.
