Antipsychotic treatment has been documented as the mainstay for the management of schizophrenia. Evidence in literature has suggested that the management of negative symptoms of schizophrenia continues to be a treatment challenge. Therefore, residual negative symptoms can become more pervasive and visible after the treatment of positive symptoms, leading to an impaired marked deficit in the vital daily functions of patients.

A central event in the pathogenesis of motor neuron disease (MND) is the loss of neuromuscular junctions (NMJs), yet the mechanisms that lead to this event in MND remain to be fully elucidated. Maintenance of the NMJ relies upon neural agrin (n-agrin) which, when released from the nerve terminal, activates the postsynaptic Muscle Specific Kinase (MuSK) signaling complex to stabilize clusters of acetylcholine receptors. Here, we report that muscle from MND patients has an increased proportion of slow fibers and muscle fibers with smaller diameter.

The dinuclear Ru complex [(Ru(phen) ) (tpphz)] (phen=1,10-phenanthroline, tpphz=tetrapyridophenazine) "RuRuPhen" blocks the transformation of G-actin monomers to F-actin filaments with no disassembly of pre-formed F-actin. Molecular docking studies indicate multiple RuRuPhen molecules bind to the surface of G-actin but not the binding pockets of established actin polymerisation inhibitors. In cells, addition of RuRuPhen causes rapid disruption to actin stress fibre organisation, compromising actomyosin contractility and cell motility; due to this effect RuRuPhen interferes with late-stage cytokinesis.

Article Synopsis
  • Eosinophils negatively impact the antiviral response of plasmacytoid dendritic cells (pDCs) by reducing the secretion of IFN-α in response to rhinovirus (RV) exposure, making asthma exacerbations worse.
  • Exposure to eosinophils inhibited IFN-α secretion in pDCs, with specific eosinophil-derived factors like neurotoxin and TGF-β contributing to this effect.
  • Treatment with anti-IL-5/5Rα therapy improved pDC antiviral function and increased IFN-α secretion, indicating it could be effective in managing respiratory infections related to eosinophilic asthma.

Article Synopsis
  • - Breast cancer is the most prevalent cancer among women and is the second leading cause of cancer deaths globally, particularly among those with estrogen receptor-positive (ER-positive) types that often develop resistance to endocrine therapy.
  • - This study employed a new statistical method to analyze gene expression changes during the development of endocrine resistance, identifying a distinct group of genes that fluctuated significantly over time during this process.
  • - The research also revealed that some of these identified genes were differently expressed in both endocrine-resistant tumors and triple-negative breast cancer (TNBC), suggesting that similar genetic factors may influence both conditions, leading to the identification of 34 novel genes as potential therapeutic targets.

Background: Identifying neural predictors of worsening subthreshold hypomania severity can help identify risk of progression to BD. While diffusion Magnetic Resonance Imaging (dMRI) studies reported white matter microstructural abnormalities in tracts supporting emotional regulation in individuals with BD, it remains unknown whether similar patterns of white matter microstructure predict worsening of subthreshold hypomania severity in non-BD individuals.

Methods: dMRI data were collected in: 81 non-BD individuals recruited across a range of subthreshold depression and hypomania, and followed for six months; and independent samples of 75 BD and 58 healthy individuals.

Fibrosis is a central pathway that drives progression of multiple chronic diseases, yet few safe and effective clinical antifibrotic therapies exist. In most fibrotic disorders, transforming growth factor-β (TGF-β)-driven scarring is an important pathologic feature and a key contributor to disease progression. Yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ) are two closely related transcription cofactors that are important for coordinating fibrogenesis after organ injury, but how they are activated in response to tissue injury has, so far, remained unclear.

Background: Independent of CD4 cell count, a low CD4/CD8 ratio in people with HIV (PWH) is associated with deleterious immune senescence, activation, and inflammation, which may contribute to carcinogenesis and excess cancer risk. We examined whether low CD4/CD8 ratios predicted cancer among PWH in the United States and Canada.

Methods: We examined all cancer-free PWH with 1 or more CD4/CD8 values from North American AIDS Cohort Collaboration on Research and Design observational cohorts with validated cancer diagnoses between 1998 and 2016.
