Intense THz pulses cause H2AX phosphorylation and activate DNA damage response in human skin tissue

Recent emergence and growing use of terahertz (11-Iz) radiation for medical imaging and public security screening raise questions on reasonable levels of exposure and health consequences of this form of electromagnetic radiation. In particular, picosecond-duration 11-Iz pulses have shown promise... Read More

Anti-Aging Potentials of Methylene Blue for Human Skin Longevity

Oxidative stress is the major cause of skin aging that includes wrinkles, pigmentation, and weakened wound healing ability. Application of antioxidants in skin care is well accepted as an effective approach to delay the skin aging process. Methylene blue (MB),... Read More

Nell1 Protein Reduces the Number of Sunburned Cells and Modulates the Inflammatory Response after UV-induced Damage in a 3D Human Skin Model

NELL1 is a novel signaling protein that mediates tissue growth and maturation during fetal development and stimulates tissue healing post-injury in adult tissues. NELL1 promotes the production of a regenerative (fetal type) extracellular matrix (ECM) that provides the structural and... Read More

Nicotinamide Metabolism Modulates the Proliferation/Differentiation Balance and Senescence of Human Primary Keratinocytes

Nicotinamide (NAM) is the main precursor of nicotinamide adenine dinucleotide (NAD+), a coenzyme essential for DNA repair, glycolysis, and oxidative phosphorylation. NAM has anti-aging activity on human skin, but the underlying mechanisms of action are unclear. Using 3-dimensional organotypic skin... Read More

Development of a chronic respiratory toxicity assay using an in vitro human airway model

Knowledge of chronic respiratory toxicity potential is important for establishing safe use of chemicals and consumer products. The current work describes efforts to develop an alternative, non-animal method for determining chronic (subacute) respiratory toxicity using the EpiAirway™ in vitro human... Read More
