Combined dandelion extract and all-trans retinoic acid induces cytotoxicity in human breast cancer cells.

Breast cancer is one of the most prevalent and deadly cancers among women worldwide. Recently, natural compounds have been widely used for the treatment of breast cancer. Present study evaluated antiproliferative and anti-metastasis activities of two natural compounds of dandelion and all-trans-retinoic acid (ATRA) in human MCF-7 and MDA-MB231 breast cancer cells.

Effect of hydroalcoholic seed extract of Nigella sativa on hepatic and pancreatic factors of Nrf2 and FGF21 in the regulation of insulin transcription factors of MafA and PDX-1 in streptozotocin-treated diabetic rats.

Introduction: Nigella sativa (N. sativa), one of the most commonly used medicinal herbs with antioxidant properties, increases blood insulin levels and lowers fasting blood sugar. Nuclear Erythroid Factor-Related Factor 2 (Nrf2) and Fibroblast Growth Factor 21 (FGF21) are two antioxidant factors that are increased by oxidative stress and hyperglycemia.

Glutamine supplementation can reduce some atherosclerosis markers after exhaustive exercise in young healthy males.

Objectives: Glutamine can be beneficial to athletes for its antiinflammatory and antioxidant effects. The present study was designed to investigate the effect of glutamine supplementation on some atherosclerosis markers after exhaustive exercise in young healthy males.

Methods: In an intervention study, 30 healthy males (case = 15 and control = 15) were randomly assigned into two groups.

Comparison of the effects of zinc oxide and zinc oxide nanoparticles on the expression of hepcidin gene in rat liver.

Objectives: Nanoparticles have special properties, such as increased intestinal absorption, permeability, and so on. Zinc oxide (ZnO) nanoparticles have medical applications such as using in drug production. Studies of ZnO nanoparticles have shown the role of these particles in reducing or increasing the genes expression.

The Effect of Glutamine Supplementation on Oxidative Stress and Matrix Metalloproteinase 2 and 9 After Exhaustive Exercise.

Background: Glutamine is the most abundant amino acid in plasma and skeletal muscles and an important fuel for immune system cells. It has beneficial anti-inflammatory and antioxidant properties which may be considered as a potentially useful supplement for athletes. The present study was conducted to investigate the effect of glutamine supplementation on oxidative stress and matrix metalloproteinase 2 and 9 after exhaustive exercise in young healthy males.

Evaluation of Haptoglobin Genotype and Some Risk Factors of Cancer in Patients with Early Stage Esophageal Cancer.

Introduction: Esophageal cancer is one of the most lethal gastrointestinal cancers that has a complex and diverse etiology, with several genetic and nutritional factors involved in its etiology. The purpose of this study was to investigate the type of haptoglobin genotype and its relationship with some nutritional and biochemical risk factors affecting the prevalence of esophageal cancer in patients with early stage esophageal cancer.

Materials And Methods: In this study, 44 patients (20 males and 24 females) with early stage esophageal cancer and 44 healthy subjects, classified as control group, (19 males and 25 females) were selected.

Effect of L-carnitine and conjugated linoleic acid supplements on haemoglobin levels and haptoglobin genotype in chronic kidney disease.

Objective: To investigate the efficacy of L-carnitine (LC) and conjugated linoleic acid (CLA) supplements on haemoglobin levels and inflammatory markers in chronic kidney disease (CKD) patients with different haptoglobin (HP) genotypes.

Methods: This clinical trial study was conducted at Imam Khomeini Hospital, Ardabil, and Labbafinejad Hospital, Tehran, Iran, from March 2014 to March 2015, and comprised male patients with CKD and anaemia. Anthropometric factors were recorded and demographic data was collected using general questionnaires.

Mesenchymal Stromal Stem Cell-Derived Microvesicles Enhance Tumor Lysate Pulsed Dendritic Cell Stimulated Autologous T lymphocyte Cytotoxicity.

Background: Immunotherapy is one promising therapeutic strategy against glioma, an aggressive form of brain cancer. Previous studies have demonstrated that multiple tumor antigens exist and can be used to induce tumor specific T cell responses. Furthermore, recently it was shown that TLR4-primed mesenchymal stem cells (MSCs), also known as MSC1, mostly elaborate pro-inflammatory mediators.

The effect of conjugated linoleic acid on oxidative stress and matrix metalloproteinases 2 and 9 in patients with COPD.

Background: Natural antioxidants in foods may be used in prevention and treatment of oxidative stress and inflammation in COPD. Therefore, this study aimed to evaluate the effect of conjugated linoleic acid (CLA) supplement as natural antioxidants on oxidative stress levels, and MMP2 and MMP9 serum levels in COPD patients.

Materials And Methods: This clinical trial study was conducted on 90 (supplement group=45 and control group=45) COPD patients in Ardabil city, Iran, in 2015.
