Endocytosis of Wnt ligands from surrounding epithelial cells positions microtubule nucleation sites at dendrite branch points.

PLoS Biol

January 2025

Biochemistry and Molecular Biology and the Huck Institutes of the Life Sciences, The Pennsylvania State University, University Park, Pennsylvania, United States of America.

Microtubule nucleation is important for microtubule organization in dendrites and for neuronal injury responses. The core nucleation protein, γTubulin (γTub), is localized to dendrite branch points in Drosophila sensory neurons by Wnt receptors and scaffolding proteins on endosomes. However, whether Wnt ligands are important is unknown.

Article Synopsis
  • A new method for C-H functionalization of heteroaryl compounds is introduced, which involves a process called dearomative addition followed by hydrogen autotransfer.
  • This process starts with the hydroruthenation of dienes to create allylruthenium nucleophiles, leading to branched C-C coupling products through addition and β-hydride elimination.
  • The study also details the formation of enantiomerically enriched heteroarylethyl alcohols and amines through oxidative cleavage and dynamic kinetic asymmetric reduction, supported by density functional theory calculations linking regioselectivities to molecular factors.

Traumatic brain injury (TBI) and subsequent post-traumatic epilepsy (PTE) often impair daily activities and mental health (MH), which contribute to long-term TBI-related disability. PTE also affects driving capacity, which impacts functional independence, community participation, and satisfaction with life (SWL). However, studies evaluating the collective impact of PTE on multidimensional outcomes are lacking.

Long-Acting Injectable Antipsychotics in Adolescents with Bipolar Disorder.

J Child Adolesc Psychopharmacol

January 2025

Director of Co-Founder and Founder of Schizophrenia Society, University of Cincinnati, Cincinnati, Ohio, USA.

Bipolar disorder often begins in adolescence or early adulthood, characterized by recurrent manic episodes that can lead to neurodegenerative brain changes and functional decline. While several oral second-generation antipsychotics are Food and Drug Administration (FDA)-approved for mania, adherence to maintenance treatment is frequently poor due to factors such as anosognosia, cognitive dysfunction, impulsivity, side effects aversion, and substance use. Long-acting injectable (LAI) antipsychotics, approved for adults with bipolar mania or schizoaffective disorder (bipolar type), offer a potential solution for adolescents with similar conditions.

Importance: Monoclonal antibodies (mAbs) targeting calcitonin gene-related peptide (CGRP) or its receptor (anti-CGRP mAbs) offer effective migraine-specific preventive treatment. However, concerns exist about their potential cardiovascular risks due to CGRP blockade.

Objective: To compare the incidence of cardiovascular disease (CVD) between Medicare beneficiaries with migraine who initiated anti-CGRP-mAbs vs onabotulinumtoxinA in the US.

Background: Liver fibrosis is caused by chronic toxic or cholestatic liver injury. Fibrosis results from the recruitment of myeloid cells into the injured liver, the release of inflammatory and fibrogenic cytokines, and the activation of myofibroblasts, which secrete extracellular matrix, mostly collagen type I. Hepatic myofibroblasts originate from liver-resident mesenchymal cells, including HSCs and bone marrow-derived CD45+ collagen type I+ expressing fibrocytes.

  • The study evaluated the use of continuous video-electroencephalography (cEEG) to detect seizures in infants and children in a cardiovascular intensive care unit (CVICU), emphasizing symptoms and risk factors that led to cEEG evaluations.
  • Among 605 cEEGs performed over 38 months, seizures were found in 9% of cases, with a significantly higher detection rate (30%) when both vital sign and non-vital sign symptoms were present, while isolated vital sign changes did not yield any seizures.
  • The results indicated that certain symptoms (like gaze deviation and abnormal limb movements) and risk factors (like preexisting epilepsy and recent neuroscience surgeries) were linked to a higher likelihood of seizure detection, highlighting

Article Synopsis
  • High-dose methotrexate (MTX) can lead to serious complications like acute kidney injury (AKI), neutropenia, and liver damage, but glucarpidase, an enzyme that breaks down MTX, shows potential benefits.
  • In a study of 708 patients with MTX-AKI across 28 cancer centers, those receiving glucarpidase had a significantly higher chance of kidney recovery and faster recovery times compared to those who did not receive the treatment.
  • Additionally, glucarpidase treatment was associated with lower rates of severe neutropenia and liver enzyme elevation, but there was no notable difference in mortality rates between the two groups.

Background: Blood shortages and utilization stewardship have motivated the trauma community to evaluate futility cutoffs during massive transfusions (MTs). Recent single-center studies have confirmed meaningful survival in ultra-MT (≥20 U) and super-MT (≥50 U), while others advocate for earlier futility cut points. We sought to evaluate whether transfusion volume and intensity cut points could predict 100% mortality in a multicenter analysis.

  • The study aimed to evaluate the safety and effectiveness of alfapump for controlling ascites and improving patients' quality of life.
  • Results showed a significant reduction in the need for therapeutic paracentesis (TP) after implanting alfapump, with most patients experiencing over a 50% decrease in sessions.
  • While some complications led to device removal, overall, the alfapump improved symptoms and physical health, suggesting it could be a viable option for patients with refractory ascites.

Article Synopsis
  • Cognitive impairment is prevalent in Parkinson's disease (PD), but there's no agreement on the best neuropsychological tests to assess it; a Cognitive Summary Score (CSS) combines various tests into a single score for easier interpretation.
  • This study aimed to see if a CSS, developed using strong norming methods, could identify early cognitive issues in untreated PD patients.
  • Results show that PD patients performed worse than healthy controls across cognitive tests, especially in processing speed and verbal memory, and the CSS provided a more sensitive measure of cognitive decline than individual tests.

Adult spinal deformity comprises a heterogeneous group of disorders that primarily affects older patients and can have a significant negative affect on health-related quality of life. Operative treatment for adult spinal deformity typically entails posterior instrumented fusions that have demonstrated the potential to significantly improve health-related quality of life outcomes. However, until fusion is achieved, the instrumentation providing structural support is subject to repetitive cyclical loading that disproportionately fatigues high-stress areas and can result in instrumentation failure.

Iron-Catalyzed Aerobic Carbonylation of Methane via Ligand-to-Metal Charge Transfer Excitation.

J Am Chem Soc

January 2025

State Key Laboratory of Organometallic Chemistry, Shanghai Institute of Organic Chemistry, University of Chinese Academy of Sciences, Shanghai 200032, China.

The integration of ligand-to-metal charge transfer (LMCT) catalytic paradigms with radical intermediates has transformed the selective functionalization of inert C-H bonds, facilitating the use of nonprecious metal catalysts in demanding transformations. Notably, aerobic C-H carbonylation of methane to acetic acid remains formidable due to the rapid oxidation of methyl radicals, producing undesired C1 oxygenates. We present an iron terpyridine catalyst utilizing LMCT to achieve exceptional C2/C1 selectivity through synergistic photoexcitation, methyl radical generation, and carbonylation.

Humeral Head-Split Fracture in Two Dogs.

Vet Radiol Ultrasound

January 2025

Royal (Dick) School of Veterinary Studies and Roslin Institute, The University of Edinburgh, Roslin, UK.

Two skeletally immature female dogs were each investigated for chronic weight-bearing thoracic limb lameness. The first patient was lame for 2 months following a tumble whilst playing, and the second patient had been intermittently lame since 3 weeks of age. In both cases, radiographic examination of the shoulder revealed fissuring of the caudal humeral head consistent with an incomplete proximal humeral Salter-Harris type IV fracture with an Enoki-mushroom-like appearance of the caudal fragment, where two heads rise from a common stem.
