Cascade enzymatic reactions in living organisms are fundamental reaction mechanisms in coordinating various complex biochemical processes such as metabolism, signal transduction, and gene regulation. Many studies have attempted to mimic cascade reactions using nanoparticles with enzyme-like activity; however, precisely tuning each reaction within complex networks to enhance the catalytic activity remains challenging. Here, we present enzyme-like chiral plasmonic nanoparticles for optically tunable catalytic cancer therapy.

Human induced pluripotent stem cell (iPSC) derived cortical organoids (hCOs) model neurogenesis on an individual's genetic background. The degree to which hCO phenotypes recapitulate the brain growth of the participants from which they were derived is not well established. We generated up to 3 iPSC clones from each of 18 participants in the Infant Brain Imaging Study, who have undergone longitudinal brain imaging during infancy.

Background: Although the incidence of sudden cardiac death is higher in hemodialysis (HD) patients, whether out-of-hospital cardiac arrest (OHCA) survival outcomes are poorer in this group remains unclear. This study aimed to assess the impact of HD on survival outcomes among adult nontraumatic OHCA patients and to compare these outcomes between HD and non-HD groups.

Methods: This observational cohort study retrospectively analyzed data from adult nontraumatic OHCA patients in Ulsan, South Korea, from January 2017 through December 2022.

Epoxides are versatile chemical intermediates that are used in the manufacture of diversified industrial products. For decades, thermochemical conversion has long been employed as the primary synthetic route. However, it has several drawbacks, such as harsh and explosive operating conditions, as well as a significant greenhouse gas emissions problem.

Purpose: This study aimed to provide quantitative information for implementing Lattice radiotherapy (LRT) using a medical linear accelerator equipped with the Millennium 120 multi-leaf collimator (MLC). The research systematically evaluated the impact of varying vertex diameters and separations on dose distribution, peak-to-valley dose ratio (PVDR), and normal tissue dose.

Methods: A cylindrical Virtual Water™ phantom was used to create LRT treatments using the Eclipse version 16.

: This study aimed to establish a predictive model for critical quality attributes (CQAs) related to tablet integrity, including tablet breaking force (TBF), friability, and capping occurrence, using machine learning-based models and nondestructive experimental data. : The machine learning-based models were trained on data to predict the CQAs of metformin HCl (MF)-containing tablets using a commercial-scale wet granulation process, and five models were each compared for regression and classification. We identified eight input variables associated with the process and material parameters that control the tableting outcome using feature importance analysis.

Acute liver failure (ALF) is characterized by rapid hepatic dysfunction, primarily caused by drug-induced hepatotoxicity. Due to the lack of satisfactory treatment options, ALF remains a fatal clinical disease, representing a grand challenge in global health. For the drug repositioning to ALF of mesalamine, which is clinically approved for the treatment of inflammatory bowel disease (IBD), we propose a supramolecular prodrug nanoassembly (SPNs).

Introduction: Metabolic dysfunction-associated steatotic liver disease (MASLD) is an important public health threat, potentially leading to chronic liver disease and liver cancer. Current guidelines recommend using the Fibrosis-4 score for initial identification of subjects at risk of future complications. We formulate a novel population screening strategy based on the Steatosis-Associated Fibrosis Estimator (SAFE) score, recently developed for MASLD risk stratification in primary care.

Background: Down syndrome (DS) is the most common congenital neurodevelopmental disorder, present in about 1 in every 700 live births. Despite its prevalence, literature exploring the neurobiology underlying DS and how this neurobiology is related to behavior is limited. This study fills this gap by examining cortical volumes and behavioral correlates in school-age children with DS.

Plasmopara viticola causes grape downy mildew, one of the most notorious diseases of cultivated grapes that damage vineyards worldwide. The pathogen secretes various effector molecules to infect and modulate the host biological processes. In this study, we aimed to evaluate the roles of KPvRxLR27, an arginine-any amino acid-leucine-arginine (RxLR) effector isolated from P.

Cerebrospinal fluid (CSF) rhinorrhea is a rare condition characterized by the leakage of CSF through the nose. The diagnosis is established through comprehensive history taking, brain imaging, and nasal endoscopy. Surgical intervention is considered a secondary option for CSF leakage when conservative treatments, including behavioral therapy, pharmacotherapy, or lumbar puncture, fail to elicit a response.

This report represents the conclusions of 15 experts in nephrology and endocrinology, based on their knowledge of key studies and evidence in the field, on the role of continuous glucose monitors (CGMs) in patients with diabetes and chronic kidney disease (CKD), including those receiving dialysis. The experts discussed issues related to CGM accuracy, indications, education, clinical outcomes, quality of life, research gaps, and barriers to dissemination. Three main goals of management for patients with CKD and diabetes were identified: (1) greater use of CGMs for better glycemic monitoring and management, (2) further research evaluating the accuracy, feasibility, outcomes, and potential value of CGMs in patients with end-stage kidney disease (ESKD) on hemodialysis, and (3) equitable access to CGM technology for patients with CKD.

Acquired resistance to chemotherapy is a major challenge in the treatment of triple-negative breast cancer (TNBC). Despite accumulated evidence showing microRNA-21 (miR-21) as a vital regulator of tumor progression, the role of miR-21 in modulating the multidrug resistance of TNBC remains obscure. In this study, we demonstrate that miR-21 affects chemoresistance in 4T1 TNBC cells in response to doxorubicin (DOX) by regulating the P-glycoprotein (P-gp) drug efflux pump.

Article Synopsis
  • * Previous gene-editing techniques using CRISPR-Cas9 had low efficiency (<10%) in enhancing CFTR function, necessitating further advancements in gene insertion methods for better therapy outcomes.
  • * Using small molecules AZD7648 and ART558 improved cDNA insertion in airway stem cells, though ART558 introduced toxicity; AZD7648 alone significantly boosted gene insertion without increasing off-target effects, warranting further research for safety and efficacy.
