Free radicals and their impact on health and antioxidant defenses: a review.

Free radicals, characterized by the presence of unpaired electrons, are highly reactive species that play a significant role in human health. These molecules can be generated through various endogenous processes, such as mitochondrial respiration and immune cell activation, as well as exogenous sources, including radiation, pollution, and smoking. While free radicals are essential for certain physiological processes, such as cell signaling and immune defense, their overproduction can disrupt the delicate balance between oxidants and antioxidants, leading to oxidative stress.

Evaluation of acute, repeated dose 28-day and 13-week oral toxicity and genotoxicity of a standardized fraction (HemoHIM) from .

HemoHIM is a functional food ingredient comprising a triple herbal combination of extracts from Nakai, Makino, and Pallas. It was developed to aid the recovery of impaired immune function. Although it is widely used to treat various immune disorders in Korea, its potential toxicity has not been extensively investigated.

3D bioprinting: Advancing the future of food production layer by layer.

3D bioprinting is an advanced manufacturing technique that involves the precise layer-by-layer deposition of biomaterials, such as cells, growth factors, and biomimetic scaffolds, to create three-dimensional living structures. It essentially combines the complexity of biology with the principles of 3D printing, making it possible to fabricate complex biological structures with extreme control and accuracy. This review discusses how 3D bioprinting is developing as an essential step in the creation of alternative food such as cultured meat and seafood.

Association between obstructive sleep apnea and hyperuricemia/gout in the general population: a cross-sectional study.

Background: Obstructive sleep apnea (OSA) is linked to various health conditions, including cardiovascular diseases and metabolic disorders. Hyperuricemia and gout may be associated with OSA, but large-scale studies on this are limited. This study aimed to investigate the association between hyperuricemia/gout and OSA using data from the Korea National Health and Nutrition Survey (KNHANES).

Evaluating current status of network pharmacology for herbal medicine focusing on identifying mechanisms and therapeutic effects.

Introduction: Network pharmacology has gained significant traction as a tool for identifying the mechanisms and therapeutic effects of herbal medicines. However, despite the usefulness of these approaches, their diversity underscores the critical need for a systematic evaluation to ensure consistency and reliability.

Objectives: We aimed to evaluate the network pharmacological analyses, focusing on identifying the mechanisms and therapeutic effects of herbal medicines.
