Impaired monoamine neural system in the mPFC of SHRSP/Ezo as an animal model of attention-deficit/hyperactivity disorder.

Attention-deficit/hyperactivity disorder (ADHD) is the most common childhood-onset psychiatric disorder. We investigated the effects of systemic administration of monoamine reuptake inhibitors on long-term potentiation (LTP) formation and monoamine release in the medial prefrontal cortex (mPFC) of the stroke-prone spontaneously hypertensive rat (SHRSP)/Ezo, an animal model of ADHD, and its genetic control, Wistar Kyoto (WKY)/Ezo, to elucidate the functional changes in the mPFC monoamine neural system. Methylphenidate (dopamine (DA) and noradrenaline (NA) reuptake inhibitor) and desipramine (NA reuptake inhibitor) improved LTP formation defects in the mPFC of SHRSP/Ezo, suggesting that NA or both DA and NA are required for improvement of impaired LTP.

Therapeutic strategies to target connective tissue growth factor in fibrotic lung diseases.

The treatment of interstitial lung diseases, including idiopathic pulmonary fibrosis (IPF), remains challenging as current available antifibrotic agents are not effective in halting disease progression. Connective tissue growth factor (CTGF), also known as cellular communication factor 2 (CCN2), is a member of the CCN family of proteins that regulates cell signaling through cell surface receptors such as integrins, the activity of cytokines/growth factors, and the turnover of extracellular matrix (ECM) proteins. Accumulating evidence indicates that CTGF plays a crucial role in promoting lung fibrosis through multiple processes, including inducing transdifferentiation of fibroblasts to myofibroblasts, epithelial-mesenchymal transition (EMT), and cooperating with other fibrotic mediators such as TGF-β.

Outcomes and prognosis of progressive pulmonary fibrosis in patients with antineutrophil cytoplasmic antibody-positive interstitial lung disease.

Approximately one-third of fibrosing interstitial lung diseases exhibit progressive pulmonary fibrosis (PPF), a clinicopathological condition distinct yet resembling idiopathic pulmonary fibrosis (IPF). PPF in ANCA-positive ILD (ANCA-ILD) is poorly documented. To clarify incidence, predictors of PPF in ANCA-ILD, and their prognostic impact, 56 patients with ANCA-ILD were followed for ≥ 1 year (April 2004 to April 2021).

Therapeutic strategies targeting pro-fibrotic macrophages in interstitial lung disease.

Idiopathic pulmonary fibrosis (IPF) is the representative phenotype of interstitial lung disease where severe scarring develops in the lung interstitium. Although antifibrotic treatments are available and have been shown to slow the progression of IPF, improved therapeutic options are still needed. Recent data indicate that macrophages play essential pro-fibrotic roles in the pathogenesis of pulmonary fibrosis.

Idiopathic pulmonary fibrosis (IPF) is a fatal lung disease characterized by progressive lung scarring. IPF-related pulmonary vascular remodeling and pulmonary hypertension (PH) result in a particularly poor prognosis. To study the pathogenesis of vascular remodeling in fibrotic lungs and its contribution to progression of fibrosis.

Genome sequence of Chionoecetes opilio bacilliform virus, a nimavirus infecting the snow crab Chionoecetes opilio.

Nimaviridae (class Naldaviricetes) is a family of double-stranded DNA viruses infecting crustaceans, with the only officially recognized representative being white spot syndrome virus (WSSV). Chionoecetes opilio bacilliform virus (CoBV) was isolated as the causative agent of milky hemolymph disease in the snow crab Chionoecetes opilio, an economically important crustacean in the northwestern Pacific. Here, we present the complete genome sequence of CoBV and show that it is unambiguously a nimavirus.

Distinct propagation patterns of right pulmonary veins through multiple epicardial connections during right atrial pacing and sinus rhythm.

A 47-year-old man with symptomatic paroxysmal atrial fibrillation (AF) underwent AF ablation. Activation maps during right atrial pacing and sinus rhythm before the ablation revealed distinctive left atrial (LA) propagations with multiple LA breakthrough sites via epicardial connections. A wide area circumferential ablation was not able to achieve a right pulmonary vein (RPV) isolation and required an inner PV ablation to isolate the RPV.

New risk scoring system for predicting 3-month mortality after acute exacerbation of idiopathic pulmonary fibrosis.

Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) is often fatal. A straightforward staging system for AE-IPF would improve prognostication, guide patient management, and facilitate research. The aim of study is to develop a multidimensional prognostic AE-IPF staging system that uses commonly measured clinical variables.

The Role for miR-146b-5p in the Attenuation of Dermal Fibrosis and Angiogenesis by Targeting PDGFRα in Skin Wounds.

As a candidate microRNA antifibrotic effector in skin wounds, miR-146b-5p was upregulated by basic FGF, and PDGFRα was identified as a direct target of miR-146b-5p in fibroblasts. The treatment of fibroblasts with a miR-146b-5p mimic markedly downregulated the expression of PDGFRα and collagen type I. miR-146b-5p mimic transfection in wounds markedly attenuated cutaneous fibrosis, whereas a miR-146b-5p inhibitor strongly promoted fibrosis, with increases in PDGFRα and collagen I levels.
