This case study describes a 29-year-old woman whose severe liver injury was primarily attributed to chronic arsenic exposure, highlighting the importance of recognizing metal toxicity in patient care.

In this case report, a 31-year-old woman with severe multisystem lupus vasculitis initially presented with generalized pain and rapidly worsening neuropathy, ultimately improving with cyclophosphamide and prednisolone treatment. The authors highlight diagnostic challenges, particularly in interpreting autoantibody results after IVIG therapy.

This study found that β-catenin signaling increases in newly born glial cells in the cortex after traumatic brain injury in mice, suggesting potential targets for enhancing recovery through the Wnt/β-catenin pathway.

This study suggests that Sonic hedgehog from hair follicles may support the proliferation of dentate neural stem cells in mice through transport by platelets during the perinatal period.

This study found that nestin-negative hair follicle stem cells can differentiate into neural stem cell-like cells, but not mature neurons, through a multi-step neuro-induction process.

Using synchrotron X-ray imaging, this study mapped the complex innervation of male rat vibrissa follicles, revealing distinct types of myelinated afferent neurons and patterns of axonal organization that may inform sensory processing in the brainstem.

This study, using a reporter mouse line, characterized diverse subtypes of dopaminergic neurons in the enteric nervous system, identifying unique subtypes with potential roles in gut function and disease.

This study found that finasteride increased fetal arousal activity in late gestation sheep by suppressing pregnane steroid synthesis, suggesting reduced GABAA receptor-mediated inhibition.

This study found that glycinergic synapses in the rat spinal cord are predominantly associated with gephyrin, though gephyrin may also be present at non-glycinergic synapses.

This study found that using the OptoTrkA system to control TrkA activity with blue light enhanced proliferation, migration, and differentiation of hair-follicle-derived stem cells into neuronal and glial cells.

This review highlights the roles of key transcription factors and signaling pathways in regulating olfactory epithelium regeneration, discussing recent advances in single-cell and spatial transcriptomics as well as organoid models to enhance understanding of olfactory regeneration mechanisms.

The researchers reported that a child with epilepsy developed encephalopathy after an asymptomatic COVID-19 infection, confirmed by clinical and laboratory assessments showing post-COVID19 effects.

Early-life neurosteroid changes affect adolescent exploration and adult behavior.

This report documents a 14-year-old Chinese boy with mitochondrial encephalopathy, lactic acidosis, stroke-like episodes, and a de novo A3243G mitochondrial DNA mutation, highlighting the condition's multisystem involvement without ragged red fibers in muscle biopsy.

This study found that blocking GABA(A) receptors in cat dorsal horn neurons increased evoked activity and background discharge, highlighting differences in inhibitory control systems compared to glycine receptors.

This study found that the dermal sheath smooth muscle regulates hair follicle progenitor cell death during hair regression through mechanical signaling of the TGF-β pathway.

This article explores the evolution of mechanosensing and discusses the diverse forms and organization of touch receptors but reports no new research findings.

This study revealed the complex three-dimensional innervation of touch domes in cat forepaw skin, highlighting the extensive branching and unmyelinated endings associated with Merkel cell–axon complexes.

This study found that both declining levels of the neurosteroid THP and increasing levels of estradiol before puberty trigger maximal expression of α4βδ GABAA receptors in the CA1 hippocampus of female mice.

This study explored the molecular mechanisms determining the identity of keratinocytes and corneal epithelial cells, finding that miRNAs from the Gtl2-Dio3 region, which regulate key signaling pathways, play a significant role in cell identity through the Hox/Gtl2-Dio3 miRNA axis.

This study suggests that mTORC1 may play a role in regulating the timing of hair growth cycle phases, particularly the initiation of the anagen phase.

This study found that the absence of Hes1 in hair follicles delays secondary hair germ activation and shortens the anagen phase, impacting HFSC self-renewal and long-term hair regeneration.

This article discusses the relationship between sedentary behavior and chronic disease, proposing that "physical inactivity disease" may be a non-permissive brain disorder with various physiological effects, but it reports no new research results.

In this study, researchers demonstrated that human hair follicle outer root sheath cells release ATP, serotonin, and histamine in response to mechanical stimulation, which subsequently activates surrounding sensory neurons.

This study found that silencing IGFBP5 reduced neurotoxicity and motor deficits in the 6-OHDA model of Parkinson's disease, likely by affecting the SHH signaling pathway, suggesting its potential role in mitigating Parkinson’s-related neuronal damage.

This study suggests that inactivation of β-catenin is necessary for chick retina regeneration, as it allows cells to enter the cell cycle during injury and promotes regeneration without needing FGF2.

This study found that actomyosin contractility in suprabasal keratinocytes influences the proliferation and differentiation of epidermal stem/progenitor cells by acting as a niche element in the skin.

CaBP1 and CaBP2 are important for continuous hearing by preventing inactivation of calcium currents in ear cells, with CaBP2 also able to restore hearing when reintroduced.
