Astrocyte regulation of critical period plasticity across neural circuits.

Curr Opin Neurobiol

December 2024

Department of Pathology and Immunology, Washington University School of Medicine, Saint Louis, MO 63110, USA; Department of Developmental Biology, Washington University School of Medicine, Saint Louis, MO 63110, USA; Brain Immunology and Glia Center, Washington University School of Medicine, Saint Louis, MO 63110, USA. Electronic address:

Critical periods are brief windows of heightened neural circuit plasticity that allow circuits to permanently reset their structure and function to facilitate robust organismal behavior. Understanding the cellular and molecular mechanisms that instruct critical period timing is of broad clinical interest, as altered developmental plasticity is linked to multiple neurodevelopmental disorders. While intrinsic, neuronal mechanisms shape both neural circuit remodeling and critical period timing, recent data indicate that signaling from astrocytes and surrounding glia can both promote and limit critical period plasticity.

ALSUntangled #77: Psilocybin.

Amyotroph Lateral Scler Frontotemporal Degener

December 2024

Department of Neurology, Duke University, Durham, NC, USA.

ALSUntangled reviews alternate and off-label treatments prompted by patient interest. Here, we review psilocybin, a chemical derived from mushrooms and belonging in the category of drugs known as psychedelics. Psilocybin has plausible mechanisms for slowing ALS progression because of its ability to cross the blood brain barrier and effect neurogenesis and inflammation.

Background: Allergic contact dermatitis cannot be reliably differentiated from other forms of spongiotic/eczematous dermatitis by histology alone. Textbooks and recent studies have variably supported the specificity of dermal eosinophils, eosinophilic spongiosis, and Langerhans cell collections, among other features.

Objective: To assess which histopathologic features favor a diagnosis of allergic contact dermatitis.

Development of a high-throughput platform for quantitation of histone modifications on a new QTOF instrument.

Mol Cell Proteomics

December 2024

Department of Biochemistry and Molecular Biophysics, Washington University School of Medicine, St. Louis, Missouri 63110, United States. Electronic address:

Histone post-translational modifications (PTMs) regulate gene expression patterns through epigenetic mechanisms. The 5 histone proteins (H1, H2A, H2B, H3, and H4) are extensively modified, with over 75 distinct modification types spanning more than 200 sites. Despite strong advances in mass spectrometry-based approaches, identification and quantification of modified histone peptides remains challenging due to factors such as isobaric peptides, pseudo-isobaric PTMs, and low stoichiometry of certain marks.

Advancing mitochondrial therapeutics: Synthesis and pharmacological evaluation of pyrazole-based inhibitors targeting the mitochondrial pyruvate carrier.

Eur J Med Chem

December 2024

Department of Anesthesiology, Washington University School of Medicine, St. Louis, MO, 63110, USA; Center for Clinical Pharmacology, Washington University School of Medicine and University of Health Sciences and Pharmacy, St. Louis, Missouri, 63110, USA; Department of Pharmaceutical and Administrative Sciences, University of Health Sciences and Pharmacy, St. Louis, Missouri, 63110, USA. Electronic address:

Inhibition of mitochondrial pyruvate transport via the mitochondrial pyruvate carrier (MPC) has shown beneficial effects in treating metabolic diseases, certain cancers, various forms of neurodegeneration, and hair loss. These benefits arise either from the direct inhibition of mitochondrial pyruvate metabolism or from the metabolic rewiring when pyruvate entry is inhibited. However, current MPC inhibitors are either nonspecific or possess poor pharmacokinetic properties.

Adaptive fusion of dual-view for grading prostate cancer.

Comput Med Imaging Graph

December 2024

National Clinical Research Center for Geriatric Disorders, Xiangya Hospital, Central South University, China; Department of Oncology, Xiangya Hospital, Central South University, Changsha, 410008, China. Electronic address:

Accurate preoperative grading of prostate cancer is crucial for assisted diagnosis. Multi-parametric magnetic resonance imaging (MRI) is a commonly used non-invasive approach, however, the interpretation of MRI images is still subject to significant subjectivity due to variations in physicians' expertise and experience. To achieve accurate, non-invasive, and efficient grading of prostate cancer, this paper proposes a deep learning method that adaptively fuses dual-view MRI images.

Division of Rehabilitation Psychology Neuropsychology, Department of Physical Medicine and Rehabilitation, University of Michigan, Ann Arbor, Michigan. Electronic address:

Background: Neonatal seizures are common with acute brain injury. Up to 25% of survivors develop postneonatal epilepsy. We hypothesized postneonatal epilepsy diagnosed by age 24 months would increase risk for early markers of neurobehavioral disorders than acute provoked neonatal seizures alone.

Introduction: Medication-resistant epilepsy (MRE) is characterized by the failure of adequate trials of two antiseizure medications (ASMs). Numerous studies have shown that once two ASMs fail to control seizures, the likelihood of subsequent ASM regimens providing seizure control diminishes significantly. Recent clinical data on cenobamate (CNB) suggest it may offer higher rates of seizure freedom in MRE patients.

Epilepsy is one of the oldest neurological disorders discovered by mankind. This condition is firmly coupled with unprovoked seizures stimulated by irrepressible neuroelectrical blasts. Orally taken valproate family has been employed for prophylactic management; however, oral administration is not applicable for critical scenarios, thus calling for medication routes fulfilling necessities of immediate innervation.

Background: Institutional Review Boards (IRBs) in the United States play a crucial role in ensuring the ethical conduct of clinical trials, including assessing the scientific merit of studies to justify the risks to participants. However, prior research suggests that many IRBs do not systematically evaluate scientific merit, raising concerns about the approval of low-quality trials.

Objective: To investigate whether IRBs provide adequate guidance on assessing scientific merit in their Standard Operating Procedures (SOPs) and other relevant materials.

Synovial sarcoma (SS) is a rare soft tissue sarcoma characterized by high-grade malignancy and poor prognosis. Preliminary research indicates that apoptosis evasion is a key factor in SS progression, primarily attributed to the overexpression of anti-apoptotic genes. However, the mechanisms underlying this phenomenon are still not fully understood.

Aims/hypothesis: Insulin resistance and compensatory hyperinsulinaemia are core features leading to beta cell failure in youth-onset type 2 diabetes. Insulin clearance (IC) is also a key regulator of insulin concentrations, but few data exist on IC in youth-onset type 2 diabetes. In a secondary analysis of our Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) randomised clinical trial, we investigated potential sex-, race-, ethnicity- and treatment-related differences in IC in youth-onset type 2 diabetes and aimed to identify metabolic phenotypes associated with IC at baseline and in response to metformin, metformin plus a lifestyle intervention, and metformin plus rosiglitazone.

Article Synopsis
  • The study investigates how different reasons for revision surgery in adult spinal deformity (ASD) patients affect their postoperative outcomes, revealing a high incidence of reoperations.
  • A sample of 891 ASD patients was analyzed retrospectively, categorizing their revisions by cause, and assessing complications, radiographic results, and disability metrics.
  • Findings suggest that different etiologies (mechanical, infection, wound, and SI pain) lead to varying outcomes, with mechanical issues showing less improvement over time compared to others.

People with low back pain (LBP) display an altered movement pattern during functional activities. Exercise-based treatments improve the altered pattern, but there is individual variability in the response to treatment. This study investigates the moderating effect of person-specific characteristics on a movement pattern at baseline and change over time in the pattern in people with chronic LBP who received motor skill training (MST) or strength and flexibility exercise (SFE).
