Cadmium (Cd), a potent carcinogen present in almost all foods, poses a major health risk to humans. Major routes of exposure to Cd for humans are occupation, diet, and tobacco use. Cd elicits various deleterious effects on cellular molecules mainly by causing oxidant-antioxidant imbalance. Cd has been implicated in the pathogenesis of many cancers, Itai-itai disease, diabetic nephropathy, hypertension, peripheral artery disease, and myocardial infarction. This study was designed to investigate the effects of Cd intake on erythrocytes and cardiac tissue in male albino Wistar rats...

INTRODUCTION: High dietary saturated fat intake is associated with higher blood concentrations of low-density lipoprotein cholesterol (LDL-C), an established risk factor for coronary heart disease. However, there is increasing interest in whether various dietary oils or fats with different fatty acid profiles such as extra virgin coconut oil may have different metabolic effects but trials have reported inconsistent results. We aimed to compare changes in blood lipid profile, weight, fat distribution and metabolic markers after four weeks consumption of 50 g daily of one of three different dietary fats, extra virgin coconut oil, butter or extra virgin olive oil, in healthy men and women in the general population...

INTRODUCTION: Tyrosine kinase inhibitors (TKIs) can safely be discontinued in chronic myeloid leukemia (CML) patients with sustained deep molecular response. ABCG2 (breast cancer resistance protein), OCT1 (organic cation transporter 1), and ABCB1 (multidrug resistance protein 1) gene products are known to play a crucial role in acquired pharmacogenetic TKI resistance. Their influence on treatment-free remission (TFR) has not yet been investigated. MATERIALS AND METHODS: RNA was isolated on the last day of TKI intake from peripheral blood leukocytes of 132 chronic phase CML patients who discontinued TKI treatment within the European Stop Tyrosine Kinase Inhibitor Study trial...

Cancer is a severe health problem that significantly undermines life span and quality. Dietary approach helps provide preventive, non-toxic and economical strategies against cancer. Increased intake of fruits, vegetables and whole grains are linked to reduced risk of cancer and other chronic diseases. The anti-cancer activities of plant-based foods are related to the actions of phytochemicals. One potential mechanism of action of anti-cancer phytochemicals is that they regulate cellular signal transduction pathways and hence affects cancer cell behaviors such as proliferation, apoptosis and invasion...

Palliative surgery for advanced gastric cancer with serious symptoms such as hemorrhage or obstruction may be meaningful in the point of improving quality of life(QOL). However, the meaning of palliative gastrojejunostomy for unresectable gastric cancer with obstruction is controversial. We retrospectively evaluated the effectiveness of gastrojejunostomy for unresectable gastric cancer with obstruction using preoperative inflammatory biomarkers. Blood lymphocyte monocyte ratio(LMR), neu- trophill ymphocyte ratio(NLR)and C-reactive protein/albumin ratio(CAR)were analyzed as inflammatory biomarkers in this study...

Vitamin B6 serves as a coenzyme catalyzing more than 150 enzymes regulating metabolism and synthesis of proteins, carbohydrates, lipids, heme, and important bioactive metabolites. For several years vitamin B6 and its vitamers (B6) were recognized as antioxidant and antiinflammatory and in modulating immunity and gene expression. During the last 10 years, there were growing reports implicating B6 in inflammation and inflammation-related chronic illnesses including cancer. It is unclear if the deficiency of B6 or additional intake of B6, above the current requirement, should be the focus...

BACKGROUND: Cachexia is a metabolic syndrome that affects up to 50-80% of cancer patients. The pathophysiology is characterized by a variable combination of reduced food intake and abnormal metabolism, including systemic inflammation and negative protein and energy balance. Despite its high clinical significance, defined diagnostic criteria and established therapeutic strategies are lacking. The 'omics' technologies provide a global view of biological systems. We hypothesize that blood-based metabolomics might identify findings in cachectic patients that could provide clues to gain knowledge on its pathophysiology, and eventually postulate new therapeutic strategies...

BACKGROUND: Chronic inflammatory conditions are associated with higher tumor incidence through epigenetic and genetic alterations. Here, we focused on an association between an inflammation marker, C-reactive-protein (CRP), and global DNA methylation levels of peripheral blood leukocytes. METHODS: The subjects were 384 healthy Japanese women enrolled as the control group of a case-control study for breast cancer conducted from 2001 to 2005. Global DNA methylation was quantified by Luminometric Methylation Assay (LUMA)...

Aberrant DNA methylation is a recognized feature in various types of human cancer, and folate has a vital role in the epigenetics of mammalian cells by supplying methyl groups for DNA methylation reactions. Fragile histidine triad (FHIT) is a tumor suppressor gene that is frequently silenced in cervical cancer (CC) and preneoplastic lesions. Promoter hypermethylation was previously observed in CC, and its epigenetic silencing has been observed at mRNA or protein levels. Changes in folate intake to modulate DNA methylation may be a mechanistic link to cancer, but this remains to be elucidated...

The mechanisms by which obesity increases cancer risk are unclear, but some lines of evidence suggest that gut microbial communities (GMC) may contribute to chronic inflammation in obese individuals through raised systemic levels of lipopolysaccharides (LPS). We evaluated associations of the GMC in stool with plasma LPS-binding protein (LBP, a measure of LPS) and C-reactive protein (CRP) concentrations in 110 premenopausal women in the United States. Diet was assessed using 3-day food records and GMCs were evaluated using pyrosequencing of the 16S rRNA gene...
