Antioxidants and Carcinogenesis

open access: yesAnnals of Medicine, 1994
It is established beyond doubt that free radicals in tissues and cells can damage DNA, proteins, carbohydrates and lipids. These potentially deleterious reactions are at least partly controlled by antioxidants capable of scavenging free radicals. It is widely believed that a proper balance between free radicals and antioxidants is essential for the ...

Ischemic Myocardium Targeting Peptide‐Guided Nanobubbles for Multimodal Imaging and Treatment of Coronary Microvascular Dysfunction

open access: yesAdvanced Healthcare Materials, EarlyView.
Nanobubbles functionalized with indocyanine green and ischemic myocardium‐targeting peptide effectively target cardiomyocytes and enable the multimodal (fluorescence, ultrasonic, and photoacoustic) imaging of ischemic myocardium in mice with coronary microvascular dysfunction (CMD).

Role of Antioxidants and Natural Products in Inflammation

open access: yesOxidative Medicine and Cellular Longevity, 2016
Inflammation is a comprehensive array of physiological response to a foreign organism, including human pathogens, dust particles, and viruses. Inflammations are mainly divided into acute and chronic inflammation depending on various inflammatory ...

Gasotransmitters in Modern Medicine: Promises and Challenges in the Use of Porous Crystalline Carriers

open access: yesAdvanced Healthcare Materials, EarlyView.
This perspective provides an overview of the growing interest in utilizing various gasotransmitters—small gaseous signaling molecules namely nitric oxide (NO), carbon monoxide (CO), and hydrogen sulfide (H2S)—for several therapeutic applications, with emphasis on the potential use of porous materials as carriers to provide safe and controlled local ...

Lycium‐Barbarum Polysaccharide‐Loaded Dual‐Crosslinked Rigid Hydrogel Enhances Bone Healing in Diabetic Bone Defects by Scavenging Reactive Oxygen Species

open access: yesAdvanced Healthcare Materials, EarlyView.
A novel hydrogel (HLBP) incorporating natural polysaccharides from goji berries is developed to enhance diabetic bone defect healing. The hydrogel efficiently scavenges ROS, improves osteogenic differentiation, and promotes in vivo bone regeneration. This strategy offers a biocompatible and localized approach, overcoming the challenges of traditional ...

A Dual‐Layer Hydrogel Barrier Integrating Bio‐Adhesive and Anti‐Adhesive Properties Prevents Postoperative Abdominal Adhesions

open access: yesAdvanced Healthcare Materials, EarlyView.
A new dual‐layer hydrogel barrier for preventing postoperative abdominal adhesions is developed. The inner layer, consisting of polyethyleneimine (PEI) and thioctic acid (TA), enhanced adhesion to moist tissues. The outer layer combines zwitterionic, thermoresponsive hyaluronic acid with anti‐inflammatory epigallocatechin gallate (EGCG) and forms a ...

Antioxidants in Infection

open access: yesJournal of Nutritional Science and Vitaminology, 1993
Endogenous oxidation reactions are essential for the normal biochemistry of life and are especially critical for leukocyte microbial killing mechanisms in host defense to infectious diseases. However, reactive oxidative intermediates can damage normal tissues unless kept under antioxidant control.

Development of Itaconate Polymers Microparticles for Intracellular Regulation of Pro‐Inflammatory Macrophage Activation

open access: yesAdvanced Healthcare Materials, EarlyView.
This study develops itaconate‐based polymer microparticles (IA‐MPs) for macrophage‐targeted intracellular delivery, overcoming the limitations of traditional itaconate administration. IA‐MPs achieve controlled release through phagocytosis, reducing pro‐inflammatory cytokine expression and reprogramming macrophage metabolism toward glycolysis.

Reactive Oxygen and Nitrogen Species in Plants

open access: yesAntioxidants
Reactive oxygen and nitrogen species (ROS and RNS) include two families of molecules that, in recent years, have been shown to be involved in a wide range of biological functions, such as seed and pollen germination, the development and regulation of ...
