Synthetic Bilirubin-Based Nanomedicine Protects Against Renal Ischemia/Reperfusion Injury Through Antioxidant and Immune-Modulating Activity.

Adv Healthc Mater

January 2025

Department of Biological Sciences, KAIST Institute for the BioCentury, Center for Precision Bio-Nanomedicine, Korea Advanced Institute of Science and Technology, Daejeon, 34141, Republic of Korea.

Renal ischemia/reperfusion injury (IRI) is a common form of acute kidney injury. The basic mechanism underlying renal IRI is acute inflammation, where oxidative stress plays an important role. Although bilirubin exhibits potent reactive oxygen species (ROS)-scavenging properties, its clinical application is hindered by problems associated with solubility, stability, and toxicity.

Reduced autoimmunity associated with deletion of host CD73.

Immunohorizons

January 2025

Department of Pediatrics, Division of Gastroenterology, McGovern Medical School, The University of Texas Health Science Center at Houston, Houston, TX, United States.

CD73 is ubiquitously expressed and regulates critical functions across multiple organ systems. The sequential actions of CD39 and CD73 accomplish the conversion of adenosine triphosphate to adenosine and shift the adenosine triphosphate-driven proinflammatory immune cell milieu toward an anti-inflammatory state. This immunological switch is a major mechanism by which regulatory T (Treg) cells control inflammation.

The effect of increased vascular afterload measures on flow rate and survival in severe aortic stenosis.

Eur Heart J Cardiovasc Imaging

January 2025

Faculty of Health and Medicine, Wallace Wurth Building (C27), Cnr High St & Botany St, UNSW Sydney, Kensington, NSW 2033, Australia.

Aims: Although an association between the systemic circulation and transaortic flow rate (TFR) is frequently hypothesized in patients with aortic stenosis (AS), it has not been demonstrated previously. We sought to explore the relationship between blood pressure (BP), vascular afterload measures, clinical history of hypertension, TFR, and survival in patients with severe AS (aortic valve area ≤ 1 cm²).

Methods And Results: We studied 323 patients ≥ 65 years (110 prospective, 213 registry analysis) who underwent transcatheter aortic valve replacement over a 5-year period.

A proteogenomic analysis of the adiposity colorectal cancer relationship identifies GREM1 as a probable mediator.

Int J Epidemiol

December 2024

International Agency for Research on Cancer (IARC/WHO), Nutrition and Metabolism Branch, Lyon, France.

Background: Adiposity is an established risk factor for colorectal cancer (CRC). The pathways underlying this relationship, and specifically the role of circulating proteins, are unclear.

Methods: Utilizing two-sample univariable Mendelian randomization (UVMR), multivariable Mendelian randomization (MVMR), and colocalization, based on summary data from large sex-combined and sex-specific genetic studies, we estimated the univariable associations between: (i) body mass index (BMI) and waist-hip ratio (WHR) and overall and site-specific (colon, proximal colon, distal colon, and rectal) CRC risk, (ii) BMI and WHR and circulating proteins, and (iii) adiposity-associated circulating proteins and CRC risk.

The secondary prevention benefits of cardiac rehabilitation and similar exercise classes for stroke survivors are well established, however post-stroke exercise participation remains low. This research aimed to explore the factors affecting participation and engagement in UK-based post-stroke cardiac rehabilitation and exercise, from the perspective of the service user and service provider. An exploratory study, using semi-structured interviews, was conducted (n = 8, service user = 4), adopting a phenomenological approach.

Background: Area-under-the-curve (AUC)-directed vancomycin therapy is recommended; however, AUC estimation in critically ill children is difficult owing to the need for multiple samples and lack of informative models.

Methods: The authors prospectively enrolled critically ill children receiving intravenous (IV) vancomycin for suspected infection and evaluated the accuracy of Bayesian estimation of AUC from a single, optimally timed sample. During the dosing interval, when clinical therapeutic drug monitoring was performed, an optimally timed sample was collected, which was determined for each subject using an established population pharmacokinetic model and the multiple model optimal function of Pmetrics, a nonparametric population pharmacokinetic modeling software.

Diabetes significantly increases the risk of serious health issues, including prolonged skin inflammation and delayed wound healing, owing to inferior glucose control and suppression of the immune system. Although traditional hydrogen (H2) therapy is slightly effective, its ability to tailor the release of H2 on the skin is limited. Accordingly, this study proposed a novel strategy for electrocatalytic H2 release under neutral conditions to promote wound healing in diabetic mice and rabbit.

The biosynthesis of mupirocin, a clinically significant antibiotic produced by sp. NCIMB 10586, is activated by the -acyl homoserine lactone (AHL) MupR/I quorum sensing (QS) system. However, to date, limited research has focused on the influence of global regulators such as the GacS/A two-component system (TCS) on the MupR/I QS system or mupirocin biosynthesis.

Intervertebral disc degeneration (IVDD) is a major contributor to chronic back pain and disability, with limited effective therapeutic options. Current treatment options, including conservative management and surgical interventions, often fail to effectively halt disease progression and come with notable side effects. IVDD is characterized by the breakdown of the extracellular matrix (ECM) and the infiltration of inflammatory cells, which exacerbate disc degeneration.

Background: Glucagon-like peptide-1 (GLP-1) agonists are an existing treatment option for patients with insulin-resistant states, which elicit further pleiotropic effects related to immune cell recruitment and vascular inflammation. GLP-1 agonists downregulate the cluster of differentiation 147 (CD147) receptor, one of several receptors for the SARS-CoV-2 spike protein that mediate viral infection of host cells.

Methods: We conducted an open-label prospective safety and tolerability study including biomarker responses of the GLP-1 agonist Liraglutide, administered for 5 days as an add-on therapy to the standard of care within 48 h of presentation in a cohort of 13 patients hospitalized with COVID-19 pneumonia.

Noncoding RNA

January 2025

Department of Life Sciences and Biotechnology, Section of Biochemistry and Molecular Biology, University of Ferrara, 44121 Ferrara, Italy.

The discovery of the involvement of microRNAs (miRNAs) in cystic fibrosis (CF) has generated increasing interest in the past years, due to their possible employment as a novel class of drugs to be studied in pre-clinical settings of therapeutic protocols for cystic fibrosis. In this narrative review article, consider and comparatively evaluate published laboratory information of possible interest for the development of miRNA-based therapeutic protocols for cystic fibrosis. We consider miRNAs involved in the upregulation of CFTR, miRNAs involved in the inhibition of inflammation and, finally, miRNAs exhibiting antibacterial activity.

Pars fractures are a common cause of lower back pain, especially among young individuals. Although computed tomography (CT) and magnetic resonance imaging (MRI) scanning are commonly used in developed regions, traditional radiography remains the main diagnostic method in many developing countries. This study assessed whether the standard radiographic angles suggested in textbooks are optimal for an Asian population since Asian groups have lower lumbar lordosis.
