Distinct clinical outcomes based on multiple serum cytokine and chemokine profiles rather than autoantibody profiles and ultrasound findings in rheumatoid arthritis: a prospective ultrasound cohort study.

Objectives: To evaluate the potential of clinical factors, ultrasound findings, serum autoantibodies, and serum cytokine and chemokine profiles as predictors of clinical outcomes in rheumatoid arthritis (RA).

Patients And Methods: We included 200 patients with RA treated with biological and targeted synthetic disease-modifying antirheumatic drugs in a prospective multicentre ultrasound cohort study. Their serum levels of multiple cytokines and chemokines, rheumatoid factors, and serum autoantibodies (anti-cyclic citrullinated peptide-2 (anti-CCP2) and anti-carbamylated protein antibodies) were measured at baseline, 3 months and 12 months.

Therapeutic Efficacy of Intranasal -Acetyl-L-Cysteine with Cell-Penetrating Peptide-Modified Polymer Micelles on Neuropathic Pain in Partial Sciatic Nerve Ligation Mice.

: We previously demonstrated that the intranasal administration of cell-penetrating Tat peptide-modified carrier, PEG-PCL-Tat, improves drug delivery to the central nervous system. This study aimed to evaluate the potential of the post-onset intranasal administration of -acetyl-L-cysteine (NAC) combined with PEG-PCL-Tat (NAC/PPT) for neuropathic pain. : Neuropathic pain was induced by partial sciatic nerve ligation (PSNL) in mice.

Fabrication and Compression Properties of Two-Layered Porous Structure of Different Materials by Direct Printing of Resin Porous Structure on Aluminum Foam Using a 3D Printer.

The porous structure, in which many pores are intentionally placed inside the material, has excellent impact energy absorption properties. Recent studies have attempted to fabricate multi-layered porous structures with different mechanical properties within a single porous structure sample, and the mechanical properties of these structures are being elucidated. However, these studies mainly attempted to vary the densities, pore structures, and alloy compositions within a single material, such as aluminum, for the entire sample.

, known for carrying the gene and linked to various diseases, is widely distributed. However, its prevalence in Ghana is unknown, mainly due to misidentification or inadequate research. In this study, for the first time, we characterized from Densu river water in Ghana.

Scalable preparation of furanosteroidal viridin, β-viridin and viridiol from Trichoderma virens.

Viridin and viridiol, along with wortmannin, metabolized by filamentous fungus Trichoderma virens, are identical furanosteroids with high-potent inhibitory activity towards phosphatidylinositol 3-kinase (PI3K) that associates the growth of tumor cells. Therefore, structure-activity relationship study (SAR) of these furanosteroids contributes to the development of novel drugs. However, rational supply methods have not been established yet.

Rspo3-mediated metabolic liver zonation regulates systemic glucose metabolism and body mass in mice.

The unique architecture of the liver consists of hepatic lobules, dividing the hepatic features of metabolism into 2 distinct zones, namely the pericentral and periportal zones, the spatial characteristics of which are broadly defined as metabolic zonation. R-spondin3 (Rspo3), a bioactive protein promoting the Wnt signaling pathway, regulates metabolic features especially around hepatic central veins. However, the functional impact of hepatic metabolic zonation, regulated by the Rspo3/Wnt signaling pathway, on whole-body metabolism homeostasis remains poorly understood.

Objective: The duration of viral shedding and criteria for de-isolation in the hospital among immunocompromised patients with coronavirus disease 2019 (COVID-19) remain unclear. This study aimed to evaluate viral shedding duration in immunocompromised patients infected with the Omicron variant of severe acute respiratory syndrome coronavirus 2.

Methods: A prospective cohort study was performed at 2 tertiary medical centers in Japan during the Omicron epidemic waves from July 2022 to January 2023.

NEIL1: the second DNA glycosylase involved in action-at-a-distance mutations induced by 8-oxo-7,8-dihydroguanine.

8-Oxo-7,8-dihydroguanine (G, 8-hydroxyguanine), an oxidatively damaged base, induces mutations and is involved in cancer initiation. In addition to G:C→T:A transversions at the damaged site, it causes untargeted base substitution (action-at-a-distance) mutations at the G bases of 5'-GpA-3' sites in human cells. Paradoxically, OGG1, a DNA glycosylase involved in the base excision repair (BER) pathway, enhances the action-at-a-distance mutations by G.

Case report: Adult case of A20 haploinsufficiency suspected as neuro-Behçet disease.

Patients with A20 haploinsufficiency (HA20) presenting with central nervous system (CNS) symptoms are rare, and available reports are limited. Here, we describe a patient with HA20, previously followed up as Behçet disease, who presented with CNS symptoms in adulthood. A 38-year-old Japanese male who had been followed up for incomplete Behçet disease at another hospital since 28 years of age presented to our hospital with acute-onset diplopia and persistent hiccups that were severe enough to cause vomiting.

Immune evasion through mitochondrial transfer in the tumour microenvironment.

Cancer cells in the tumour microenvironment use various mechanisms to evade the immune system, particularly T cell attack. For example, metabolic reprogramming in the tumour microenvironment and mitochondrial dysfunction in tumour-infiltrating lymphocytes (TILs) impair antitumour immune responses. However, detailed mechanisms of such processes remain unclear.

The two-part MiroCIP study included interventional and prospective observational studies. Here, we report the latter, describing CIPN incidence, risk factors, and outcomes.

Enhanced charge transfer kinetics at the electrode/electrolyte interface in acetonitrile solvent for lithium-ion battery cathodes.

Acetonitrile is a low-viscosity solvent that can enhance charge transfer kinetics at the electrode/electrolyte interface, although its cathodic instability limits its demonstration. This study employed a dual-compartment cell separated by a solid electrolyte to demonstrate that an acetonitrile-based electrolyte enhanced the interfacial charge transfer kinetics compared to those of carbonate-based electrolytes.

Gas-Liquid Interface of Aqueous Solutions of Surface Active Aromatic Molecules Studied Using Extreme Ultraviolet Laser Photoelectron Spectroscopy and Molecular Dynamics Simulation.

We investigated the gas-liquid interface of aqueous solutions containing phenol and related aromatic compounds using extreme ultraviolet laser photoelectron spectroscopy and molecular dynamics simulations. The interfacial densities of protonated and deprotonated forms of phenol, aniline, and 4-nitrophenol were found to be primarily determined by their surface affinities and exhibit similar concentration dependences to their respective bulk densities. Despite the distinct interfacial orientations of their permanent dipole moments, these compounds monotonically decreased the surface potential at higher concentrations.

Review and meta-analysis of gene expression biomarkers predictive of chemical-induced genotoxicity in vivo.

There is growing recognition across broad sectors of the toxicology community that gene expression biomarkers have the potential to identify genotoxic and nongenotoxic carcinogens through a weight-of-evidence approach, providing opportunities to reduce reliance on the 2-year bioassay to identify carcinogens. In August 2022, a workshop within the International Workshops on Genotoxicity Testing (IWGT) was held to critically review current methods to identify genotoxicants using various 'omics profiling methods. Here, we describe the findings of a workshop subgroup focused on the state of the science regarding the use of biomarkers to identify chemicals that act as genotoxicants in vivo.

Recyclable and air-stable colloidal manganese nanoparticles catalyzed hydrosilylation of alkenes with tertiary silane.

We synthesized ,-dimethylformamide (DMF)-stabilized manganese nanoparticles (Mn NPs) in a one-step process under air using manganese(ii) chloride as the precursor. The Mn NPs were characterized in terms of particle size, oxidation state, and local structure using annular dark-field scanning transmission electron microscopy (ADF-STEM), X-ray photoelectron spectroscopy (XPS), and X-ray absorption spectroscopy (XAS). The results indicate that Mn NPs are divalent nanosized particles with Mn-O bonds.

Objective: To investigate the association between preoperative aqueous humour (AqH) cytokines and mid-term endothelial cell density (ECD) following penetrating keratoplasty (PKP).

Methods: This study analysed a total of 87 eyes of which 54 underwent PKP and 33 eyes underwent cataract surgery. AqH samples were collected at the beginning of surgery.

DDX1 is required for non-spliceosomal splicing of tRNAs but not of XBP1 mRNA.

RNA helicase DEAD-box helicase 1 (DDX1) forms a complex with the RNA ligase 2´,3´-cyclic phosphate and 5´-OH ligase (RTCB), which plays a vital role in non-spliceosomal splicing of tRNA and X-box binding protein 1 (XBP1) mRNA. However, the importance of DDX1 in non-spliceosomal splicing has not been clarified. To analyze the functions of DDX1 in mammalian cells, we generated DDX1 cKO cells from the polyploid human U2OS cell line and found that splicing of intron-containing tRNAs was significantly disturbed in DDX1-deficient cells, whereas endoplasmic reticulum (ER) stress-induced splicing of XBP1 mRNA was unaffected.

Tulip mild mottle mosaic disease, caused by tulip mild mottle mosaic virus (TMMMV, species Ophiovirus tulipae), was first reported in Japan in 1979. TMMMV has a negative-sense ssRNA genome and is closely related to ophioviruses such as Mirafiori lettuce big vein virus (MLBVV, Ophiovirus mirafioriense). However, its complete nucleotide sequence has not yet been reported.

A new preprocedural predictive risk model for post-endoscopic retrograde cholangiopancreatography pancreatitis: The SuPER model.

Background: Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is a severe and deadly adverse event following ERCP. The ideal method for predicting PEP risk before ERCP has yet to be identified. We aimed to establish a simple PEP risk score model (SuPER model: Support for PEP Reduction) that can be applied before ERCP.

Acquired sperm hypomethylation by gestational arsenic exposure is re-established in both the paternal and maternal genomes of post-epigenetic reprogramming embryos.

Background: DNA methylation plays a crucial role in mammalian development. While methylome changes acquired in the parental genomes are believed to be erased by epigenetic reprogramming, accumulating evidence suggests that methylome changes in sperm caused by environmental factors are involved in the disease phenotypes of the offspring. These findings imply that acquired sperm methylome changes are transferred to the embryo after epigenetic reprogramming.
