  • Inflammatory bowel disease (IBD) involves chronic inflammation in the gastrointestinal tract, and developing a reliable oral drug delivery system to target inflammation is a major challenge.
  • Researchers created pH-responsive hyaluronic acid-coated Eudragit S100 nanoparticles (HA-BUD-ES-NPs) for delivering budesonide, which demonstrated stable properties and effective drug release in simulations of the gastrointestinal environment.
  • In tests with Caco-2 cells and a rat model of colitis, HA-BUD-ES-NPs improved budesonide effectiveness, reduced inflammation, and showed better results in disease symptoms and histopathology compared to traditional drug forms.

Article Abstract

Inflammatory bowel disease (IBD) is characterized by chronic inflammation along the gastrointestinal tract. For IBD effective treatment, developing an orally administered stable drug delivery system capable of targeting inflammation sites is a key challenge. Herein, we report pH responsive hyaluronic (HA) coated Eudragit S100 (ES) nanoparticles (NPs) for the targeted delivery of budesonide (BUD) (HA-BUD-ES-NPs). HA-BUD-ES-NPs showed good colloidal properties (274.8 ± 2.9 nm and - 24.6 ± 2.8 mV) with high entrapment efficiency (98.3 ± 3.41%) and pH-dependent release profile. The negative potential following incubation in simulated gastrointestinal fluids reflected the stability of HA coat. In vitro studies on Caco-2 cells showed HA-BUD-ES-NPs biocompatibility and enhanced cellular uptake and anti-inflammatory effects as shown by the significant reduction in IL-8 and TNF-α. The oral administration of HA-BUD-ES-NPs in an acetic acid induced colitis rat model significantly mitigated the symptoms of IBD, and improved BUD therapeutic efficacy compared to drug suspension. This was proved via the improvement in disease activity index and ulcer score in addition to refined histopathological findings. Also, the assessment of inflammatory markers, epithelial cadherin, and mi-R21 all reflected the higher efficiency of HA-BUD-ES-NPs compared to free drug and uncoated formulation. We thus suggest that HA-BUD-ES-NPs provide a promising drug delivery platform for the management and site specific treatment of IBD.

Late-Stage C-H Functionalization of Dehydroalanine-Containing Peptides with Arylthianthrenium Salts and Its Application in Synthesis of Tentoxin Analogue.

Org Lett

January 2025

Dehydrophenylalanine has a characteristic unsaturated double bond that makes it indispensable in the context of peptides and proteins. In this study, we report the Pd-catalyzed C(sp)-H arylation of dehydroalanine-containing peptides with arylthianthrenium salts under mild and base free conditions, which provides efficient access to dehydrophenylalanine-containing peptides. This approach enables the efficient coupling of different drug scaffolds and bioactive molecules to the peptides.

Timely delivery of care in neurological emergencies: can standardized management protocols help?

Curr Opin Crit Care

January 2025

The George Institute for Global Health, Faculty of Medicine, University of New South Wales, Sydney, NSW, Australia.

Purpose Of Review: To review the evidence that supports the implementation of goal-directed care bundle protocols to improve outcomes from neurocritical conditions, and of the possible advantage of specific over generalized protocols.

Recent Findings: Articles from January 1, 2023 to July 31, 2024 were searched to evaluate the effectiveness of standardized management in neurological emergencies. The use of care bundles and standardized protocols with time- and target-related metrics has shown benefit in patients with acute stroke and traumatic brain injury.

Restenosis remains a long-standing limitation to effectively maintain functional blood flow after percutaneous transluminal angioplasty (PTA). While the use of drug-coated balloons (DCBs) containing antiproliferative drugs has improved patient outcomes, limited tissue transfer and poor therapeutic targeting capabilities contribute to off-target cytotoxicity, precluding adequate endothelial repair. In this work, a DCB system was designed and tested to achieve defined arterial delivery of an antirestenosis therapeutic candidate, cadherin-2 (N-cadherin) mimetic peptides (NCad), shown to selectively inhibit smooth muscle cell migration and limit intimal thickening in early animal PTA models.

Background: The placement of breast implants in a prepectoral plane has become increasingly popular in breast reconstruction, although data on how this affects radiation delivery in women with breast cancer are limited. This study aimed to assess the dosimetric differences in radiation plans for immediate breast reconstruction between prepectoral and subpectoral implants.

Methods: In this study, a retrospective review and dosimetric analysis of patients with breast cancer who underwent immediate implant-based reconstruction and postmastectomy radiation therapy (PMRT) were performed.

Portal vein tumor thrombus (PVTT) is a poor prognostic factor for hepatocellular carcinoma (HCC) patients, highlighting the need for an oral drug delivery system that combines convenience, simplicity, biosafety, and improved patient compliance. Leveraging the unique anatomy of the portal vein and insights from single-cell RNA sequencing of the PVTT tumor microenvironment, we developed oral pellets using CaCO@PDA nanoparticles (NPs) encapsulating both doxorubicin hydrochloride and low molecular weight heparin. These NPs target the tumor thrombus microenvironment, aiming to break down the thrombus barrier and turn the challenge of portal vein blockage into an advantage by enhancing drug delivery efficiency through oral administration.
