Cyclosporin A as an adjunct may enhance the therapeutic effect of interferon alpha-2a in patients with refractory Behcet's uveitis: a retrospective cohort study.

Background: The application of biologic agents has benefited patients with Behcet's uveitis (BU) who do not respond to conventional treatment regimens. However, there is currently no consensus on the optimal treatment regimen of interferon alpha-2a (IFN-α2a) for refractory BU.

Objectives: To evaluate treatment outcomes and safety of IFN-α2a in a large series of refractory BU patients and to explore whether nonbiologic immunomodulatory agents (cyclosporin A) other than corticosteroids should be concomitantly used.

Machine learning-optimized non-invasive brain stimulation and treatment response classification for major depression.

Background/objectives: Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation intervention that shows promise as a potential treatment for depression. However, the clinical efficacy of tDCS varies, possibly due to individual differences in head anatomy affecting tDCS dosage. While functional changes in brain activity are more commonly reported in major depressive disorder (MDD), some studies suggest that subtle macroscopic structural differences, such as cortical thickness or brain volume reductions, may occur in MDD and could influence tDCS electric field (E-field) distributions.

Butyrate attenuates intestinal inflammation in Crohn's disease by suppressing pyroptosis of intestinal epithelial cells via the cGSA-STING-NLRP3 axis.

Butyrate can strengthen the intestinal epithelial barrier. However, the mechanisms by which butyrate affects intestinal epithelial cells (IECs) pyroptosis in Crohn's disease (CD) remain unclear. In this study, we collected colonic biopsy samples from CD patients and healthy controls to assess pyroptosis levels.

Nematicidal effects of silencing arginine kinase in the pine wood nematode, Bursaphelenchus xylophilus, determined using a dsRNA-like siRNA assembly.

The pine wood nematode Bursaphelenchus xylophilus is a highly invasive species responsible for the widespread pine wilt disease. Double-stranded RNA (dsRNA) biopesticides represent a novel strategy for controlling plant-parasitic nematodes. The B.

Overview of class I HDAC modulators: Inhibitors and degraders.

Class I histone deacetylases (HDACs) are closely associated with the development of a diverse array of diseases, including cancer, neurodegenerative disorders, HIV, and inflammatory diseases. Considering the essential roles in tumorigenesis, class I HDACs have emerged as highly desirable targets for therapeutic strategies, particularly in the field of anticancer drug development. However, the conventional class I HDAC inhibitors faced several challenges such as acquired resistance, inherent toxicities, and limited efficacy in inhibiting non-enzymatic functions of HDAC.

Integrated multi-omics reveal gut microbiota-mediated bile acid metabolism alteration regulating immunotherapy responses to anti-α4β7-integrin in Crohn's disease.

Gut microbiota and related metabolites are both crucial factors that significantly influence how individuals with Crohn's disease respond to immunotherapy. However, little is known about the interplay among gut microbiota, metabolites, Crohn's disease, and the response to anti-α4β7-integrin in current studies. Our research utilized 2,4,6-trinitrobenzene sulfonic acid to induce colitis based on the humanized immune system mouse model and employed a combination of whole-genome shotgun metagenomics and non-targeted metabolomics to investigate immunotherapy responses.

Long-term remission achieved in a rare case of pyoderma gangrenosum and ulcerative colitis with surgery and postoperative infliximab.

Background Pyoderma gangrenosum (PG) is a rare extraintestinal manifestation of inflammatory bowel disease. In recent years, the use of biologics in PG has been on the rise and has shown promising results. The surgical treatment of PG remains a topic of debate, with limited reports on the use of postoperative biologic therapy.

Promising derivatives of rutaecarpine with diverse pharmacological activities.

Rutaecarpine (RUT) is a natural pentacyclic indolopyridoquinazolinone alkaloid first isolated from one of the most famous traditional Chinese herbs, , which is used for treating a variety of ailments, including headaches, gastrointestinal disorders, hemorrhage, amenorrhea, difficult menstruation, and other diseases. Accumulating pharmacological studies showed that RUT possesses a wide range of pharmacological effects through different mechanisms. However, its poor physicochemical properties and moderate biological activities have hampered its clinical application.

Gut microbiota-related bile acid metabolism-FXR/TGR5 axis impacts the response to anti-α4β7-integrin therapy in humanized mice with colitis.

The gut microbiota and bile acid metabolism are key determinants of the response of inflammatory bowel disease to biologic therapy. However, the molecular mechanisms underlying the interactions between the response to anti-α4β7-integrin therapy and the gut microbiota and bile acid metabolism remain unknown. In this research, we investigated the role of gut microbiota-related bile acid metabolism on the response to anti-α4β7-integrin therapy in a humanized immune system mouse model with colitis induced by 2,4,6-trinitrobenzene sulfonic acid.

Machine-learning defined precision tDCS for improving cognitive function.

Background: Transcranial direct current stimulation (tDCS) paired with cognitive training (CT) is widely investigated as a therapeutic tool to enhance cognitive function in older adults with and without neurodegenerative disease. Prior research demonstrates that the level of benefit from tDCS paired with CT varies from person to person, likely due to individual differences in neuroanatomical structure.

Objective: The current study aims to develop a method to objectively optimize and personalize current dosage to maximize the functional gains of non-invasive brain stimulation.

Oxidized quercetin has stronger anti-amyloid activity and anti-aging effect than native form.

Quercetin (QUE) is one of the most widely distributed and used flavonoid. It has many biological activities and pharmacological effect. As a polyhydroxy phenol, QUE is easily oxidized.

Comparative efficacy and safety of combination therapy with infliximab for Crohn's disease: a systematic review and network meta-analysis.

Purpose: There is not enough information to position medications for the treatment of Crohn's disease (CD). Therefore, using a network meta-analysis and systematic review, we evaluated the efficacy and safety of combination therapy and infliximab (IFX) monotherapy in CD patients.

Methods: We identified randomized controlled trials (RCTs) in CD patients who were given IFX-containing combination therapy versus IFX monotherapy.

Fast water channeling across carbon nanotubes in far infrared terahertz electric fields.

Using molecular dynamics simulations, we investigate systematically the water permeation properties across single-walled carbon nanotubes (SWCNT) in the presence of the terahertz electric field (TEF). With the TEF normal to the nanotube, the fracture of the hydrogen bonds results in the giant peak of net fluxes across the SWCNT with a three-fold enhancement centered around 14 THz. The phenomenon is attributed to the resonant mechanisms, characterized by librational, rotational, and rotation-induced responses of in-tube polar water molecules to the TEF.
