Introduction: Despite increasing studies confirming the efficacy of vedolizumab (VDZ) in Crohn's disease (CD), improving the responses to this biologic agent remains challenging in clinical practice. In this article, we investigated the efficacy of combined treatment of VDZ and 16-week exclusive enteral nutrition (EEN) in moderately to severely active CD.

Methods: From October 2020 to October 2023, 81 patients with moderately to severely active CD treated with VDZ from 2 inflammatory bowel disease centers were retrospectively selected.

Article Synopsis
  • Genomic alterations in tumors significantly influence cancer progression and treatment response, with whole-genome sequencing (WGS) emerging as a viable alternative to traditional targeted panel sequencing (TPS) due to advancements in cost and technology.
  • A study involving 120 cancer patients evaluated the clinical utility of WGS and found that 79% received genomic reports quickly, with 72% of these reports offering clinically relevant information.
  • The insights gained from WGS helped in selecting tailored treatments and clinical trials based on identifying specific mutations, potentially enhancing precision oncology and suggesting routine integration of WGS in cancer management.

Interleukin (IL)-23 and IL-17 are well-validated therapeutic targets in autoinflammatory diseases. Antibodies targeting IL-23 and IL-17 have shown clinical efficacy but are limited by high costs, safety risks, lack of sustained efficacy, and poor patient convenience as they require parenteral administration. Here, we present designed miniproteins inhibiting IL-23R and IL-17 with antibody-like, low picomolar affinities at a fraction of the molecular size.

Background: Dual antiplatelet treatment has been shown to lower the risk of recurrent stroke as compared with aspirin alone when treatment is initiated early (≤24 hours) after an acute mild stroke. The effect of clopidogrel plus aspirin as compared with aspirin alone administered within 72 hours after the onset of acute cerebral ischemia from atherosclerosis has not been well studied.

Methods: In 222 hospitals in China, we conducted a double-blind, randomized, placebo-controlled, two-by-two factorial trial involving patients with mild ischemic stroke or high-risk transient ischemic attack (TIA) of presumed atherosclerotic cause who had not undergone thrombolysis or thrombectomy.

Objective: This study addresses declining physical fitness among Korean firefighters due to a low exercise participation rate caused by the absence of exercise instructors. The research explores Virtual Mate (VM), a Kinect-based mixed reality device, as a potential solution, but its capacity to replace training instructors in enhancing physical fitness remains uncertain.

Methods: Twenty Korean male firefighters were divided into two groups: the exercise group received an 8-week intervention using VM, while the control group maintained regular physical activity.

External control of chemical reactions in biological settings with spatial and temporal precision is a grand challenge for noninvasive diagnostic and therapeutic applications. While light is a conventional stimulus for remote chemical activation, its penetration is severely attenuated in tissues, which limits biological applicability. On the other hand, ultrasound is a biocompatible remote energy source that is highly penetrant and offers a wide range of functional tunability.

Numerous efforts in basic and clinical studies have explored the potential anti-aging and health-promoting effects of NAD-boosting compounds such as nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN). Despite these extensive efforts, our understanding and characterization of their whole-body pharmacodynamics, impact on NAD tissue distribution, and mechanism of action in various tissues remain incomplete. In this study, we administered NMN via intraperitoneal injection or oral gavage and conducted a rigorous evaluation of NMN's pharmacodynamic effects on whole-body NAD homeostasis in mice.

Background: Vascular aging, as assessed by structural and functional arterial properties, is an independent predictor of cardiovascular outcomes. We aimed to explore the associations of individual cardiovascular risk factors from childhood to midlife and their accumulation over a 30-year span with vascular aging in midlife.

Methods: Using data from the ongoing cohort of Hanzhong Adolescent Hypertension study, 2180 participants aged 6 to 18 years at baseline were followed for over 30 years.

Objective: The Candidate Physical Capability Test (CPAT) has been used in many countries to assess the fitness levels of firefighters, but it requires a special facility with a space of at least 900 square m 2 and expensive equipment. Because it can be difficult to have both money and space at smaller gas stations, we have developed the Korean Firefighter Performance Battery (KFPB).

Methods: To verify the validity and reliability of the developed KFPB, this study consists of three parts, a validation test, reliability test, and evaluation criterion.

Background: Aldosterone-producing adenoma (APA) is a benign adrenal tumor with autonomous aldosterone production which causes hypertension and excess cardiovascular risk. Protein phosphorylation regulates aldosterone secretion from adrenal cortical cells, but how signaling networks are remodeled in APA remains unknown.

Methods: We performed an integrated proteomic and phosphoproteomic profiling of 15 APA and 10 matched nonfunctioning adrenocortical tumors (NFAT) based on the 4-dimensional label-free technique.

  • Several studies have shown that people with Parkinson's disease (PD) have a unique gut microbiome, but there's limited research on the oral microbiome's role in PD.
  • By using advanced shotgun metagenomic sequencing, researchers found significant differences in the oral and gut microbiome between PD patients and healthy individuals.
  • Notably, PD patients had higher levels of Lactobacillus in their mouths, which correlated with harmful gut bacteria, and their microbiome showed reduced gene markers for certain amino acid production but increased markers for antimicrobial resistance.

Although diamine-appended metal-organic framework (MOF) adsorbents exhibit excellent CO adsorption performance, a continuous decrease in long-term capacity during repeated wet cycles remains a formidable challenge for practical applications. Herein, we present the fabrication of diamine-appended Mg(dobpdc)-alumina beads (-; een = -ethylethylenediamine; = number of carbon atoms attached to epoxide) coated with hydrophobic silanes and alkyl epoxides. The reaction of epoxides with diamines in the portal of the pore afforded sufficient hydrophobicity, hindered the penetration of water vapor into the pores, and rendered the modified diamines less volatile.

Background And Objectives: Individuals with cerebellar ataxia (CA) can develop impulsive behavioral symptoms, often resulting in negative interpersonal consequences, detrimentally affecting their quality of life. Limited evidence exists concerning impulsivity in CA and its associated behavioral changes. We assessed impulsive traits in CA using the Barratt Impulsivity Scale (BIS-11) and compared them with those of Parkinson disease (PD) to investigate the differences in the impulsive trait profiles between CA and PD.
