Brain mitochondrial damage attenuation by quercetin and N-acetyl cysteine: peripheral and central antiemetic effects.

Nausea serves as a protective mechanism in organisms to prevent excessive consumption of toxic substances. Due to the adverse effects of chemical anti-nausea drugs, there is a growing interest in using herbal remedies and natural antioxidants. In this study, we evaluated the neuroprotective effects of quercetin (QU) and N-acetylcysteine (NAC) against oxidative damage induced by nausea.

The analgesic effect of curcumin and nano-curcumin in clinical and preclinical studies: a systematic review and meta-analysis.

Chronic pain remains a treatment challenge. Curcumin, a natural plant product found in the Curcuma genus, has been shown to possess anti-inflammatory, antioxidant, and neuroprotective properties. In this systematic review and meta-analysis, we aimed to evaluate the efficacy of curcumin and nano-curcumin for treating chronic pain in clinical and preclinical studies.

The beneficial impact of curcumin on cardiac lipotoxicity.

Lipotoxicity is defined as a prolonged metabolic imbalance of lipids that results in ectopic fat distribution in peripheral organs such as the liver, heart, and kidney. The harmful consequences of excessive lipid accumulation in cardiomyocytes cause cardiac lipotoxicity, which alters the structure and function of the heart. Obesity and diabetes are linked to lipotoxic cardiomyopathy.

Regulatory effects of curcumin on nitric oxide signaling in the cardiovascular system.

The continuously rising prevalence of cardiovascular disease (CVD) globally substantially impacts the economic growth of developing countries. Indeed, one of the leading causes of death worldwide is unfavorable cardiovascular events. Reduced nitric oxide (NO) generation is the pathogenic foundation of endothelial dysfunction, which is regarded as the first stage in the development of a number of CVDs.

A Golden Shield: The Protective Role of Curcumin Against Liver Fibrosis.

Several chronic liver injuries can result in liver fibrosis, a wound-healing response defined by an excessive buildup of diffuse extracellular matrix (ECM). Liver fibrosis may progress to liver cirrhosis, liver failure, or hepatocellular carcinoma. Many cellular routes are implicated in the fibrosis process; however, hepatic stellate cells appear to be the main cell type involved.

Polymorphism of LRP4 Gene (rs9667108) among Post Menopause Women with Osteoporosis.

Background: Many studies have been done to identify the factors that influence the development and progression of osteoporosis. One genetic factor is polymorphisms of gene. Regarding the lack of comprehensive study on polymorphisms of gene in the north of Iran, mainly Mazandaran Province, we decided to investigate the polymorphism of this gene in postmenopausal women with osteoporosis.

Hydrogen Sulfide: Physiological Roles and Therapeutic Implications against COVID-19.

The COVID-19 pandemic due to severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) poses a major menace to economic and public health worldwide. Angiotensin-converting enzyme 2 (ACE2) and transmembrane protease serine 2 (TMPRSS2) are two host proteins that play an essential function in the entry of SARS-- COV-2 into host cells. Hydrogen sulfide (HS), a new gasotransmitter, has been shown to protect the lungs from potential damage through its anti-inflammatory, antioxidant, antiviral, and anti-aging effects.
