This review explores the mechanisms by which heavy metals such as arsenic, lead, cadmium, and mercury induce toxicity through oxidative stress by generating reactive oxygen and nitrogen species, disrupting cellular defense mechanisms, and impairing essential enzymes and proteins. Chelation therapy, using agents like CaNa₂EDTA, BAL, DMPS, and DMSA, is a
This study examined the effectiveness of melatonin and N-acetylcysteine (NAC), both alone and in combination with the chelating agent meso 2,3-dimercaptosuccinic acid (DMSA), in mitigating lead-induced oxidative stress in male rats. The research evaluated reductions in lead concentrations in blood and soft tissues, as well as the restoration of hematopoietic,
This observational study examined the protective role of methylene blue (MB) in Alzheimer’s disease (AD), demonstrating its potential as a therapeutic agent by enhancing mitochondrial function and acting as an antioxidant. MB improves cellular respiration and ATP production by serving as an alternative electron carrier, reduces oxidative stress, and provides
This review consolidates current research on L-Carnitine supplementation and its potential benefits for male fertility, incorporating in vitro, animal, and clinical studies. L-Carnitine has been shown to improve sperm motility, morphology, and concentration while regulating hormone levels and reducing oxidative stress, which may enhance fertility outcomes. These effects are attributed
The study titled “Pregnenolone Inhibits Osteoclast Differentiation and Protects Against Lipopolysaccharide-Induced Inflammatory Bone Destruction and Ovariectomy-Induced Bone Loss” explores the impact of pregnenolone (Preg) on osteoclast differentiation and bone resorption. The research demonstrated that Preg inhibits RANKL-induced osteoclast differentiation and bone resorption by downregulating specific osteoclast marker genes and suppressing
Methylene blue (MB) demonstrates neuroprotective potential by acting as an alternative electron carrier in the mitochondrial electron transport chain, bypassing dysfunctions in complexes I and III. This mechanism enhances mitochondrial respiration, reduces reactive oxygen species, and prevents cellular energy failure. In animal models of Parkinson’s disease and cerebral ischemia, MB
Methylene blue (MB) demonstrates potential as a therapeutic agent by enhancing mitochondrial function and altering energy metabolism. Acting as an alternative electron carrier, MB bypasses mitochondrial dysfunction, increasing oxygen consumption, decreasing glycolysis, and improving glucose uptake. In rodent models, MB enhanced regional cerebral blood flow and provided neuroprotection, while in
This in vitro study examined the effects of methylene blue (MB) on mitochondrial function in isolated guinea pig brain mitochondria, assessing its impact on oxygen consumption, ATP production, mitochondrial membrane potential, calcium uptake, and hydrogen peroxide (H₂O₂) production. MB enhanced mitochondrial bioenergetics by increasing ATP production, restoring membrane potential, and
This review explores the potential neuroprotective role of methylene blue (MB), particularly its ability to enhance mitochondrial function in neurodegenerative diseases such as Alzheimer’s disease, Parkinson’s disease, stroke, and traumatic brain injury. MB acts as an alternative electron carrier in the mitochondrial electron transport chain, improving ATP production and reducing
This study investigates the effects of methylene blue (MB) on mitochondrial function and oxidative stress in diabetic rat heart mitochondria. The results showed that MB administration enhanced mitochondrial respiration in both healthy and diabetic rat hearts, particularly when complex I and II substrates were used. However, MB increased hydrogen peroxide
