14,15-Dihydroxyeicosatrienoic acid, a soluble epoxide hydrolase metabolite in blood, is a predictor of anthracycline-induced cardiotoxicity - a hypothesis generating study.

Background: Early identification of patients susceptible to chemotherapy-induced cardiotoxicity could lead to targeted treatment to reduce cardiac dysfunction. Rats treated with doxorubicin (DOX), a chemotherapeutic agent, have increased cardiac expression of 14,15-dihydroxyeicosatrienoic acid (14,15-DHET), a bioactive lipid implicated in hypertension and coronary artery disease. However, the utility of 14,15-DHET as plasma biomarkers was not defined.

Metabolically healthy obese vs. Metabolic syndrome - The crosslink between nutritional exposure to bisphenols and physical exercise.

Obesity has become a worldwide pandemic as well as a major contributing factor to the increasing rate of type 2 diabetes (T2D). However, there is an intriguing variance demonstrated by a subset of obesity defined as metabolically healthy obesity (MHO). MHO individuals are less prone to develop obesity-related metabolic complications, such as metabolic syndrome (MetS) and further T2D.

Levels of plasma glycan-binding auto-IgG biomarkers improve the accuracy of prostate cancer diagnosis.

Strategies to improve the early diagnosis of prostate cancer will provide opportunities for earlier intervention. The blood-based prostate-specific antigen (PSA) assay is widely used for prostate cancer diagnosis but specificity of the assay is not satisfactory. An algorithm based on serum levels of PSA combined with other serum biomarkers may significantly improve prostate cancer diagnosis.

Transcription of mtDNA and dyslipidemia are ameliorated by aerobic exercise in type 2 diabetes.

Physical inactivity and unhealthy food intake are strongly associated with the growing prevalence of type 2 diabetes (T2D). Dyslipidemia, a characteristic of T2D patient, contributes to an increase in intra-myocellular lipid accumulation and mitochondria dysfunction, in skeletal muscle cells and further to insulin resistance. The aim of this study was to evaluate the effect of aerobic exercise on dyslipidemia, mitochondrial homeostasis and mitochondrial DNA (mtDNA) transcription in T2D- induced animals.

The role of mitochondrial DNA damage at skeletal muscle oxidative stress on the development of type 2 diabetes.

Reduced cellular response to insulin in skeletal muscle is one of the major components of the development of type 2 diabetes (T2D). Mitochondrial dysfunction involves in the accumulation of toxic reactive oxygen species (ROS) that leads to insulin resistance. The aim of this study was to verify the involvement of mitochondrial DNA damage at ROS generation in skeletal muscle during development of T2D.

The effect of exercise on skeletal muscle glucose uptake in type 2 diabetes: An epigenetic perspective.

Changes in eating habits and sedentary lifestyle are main contributors to type 2 diabetes (T2D) development, and studies suggest that epigenetic modifications are involved with the growing incidence of this disease. Regular exercise modulates many intracellular pathways improving insulin resistance and glucose uptake in skeletal muscle, both early abnormalities of T2D. Mitochondria dysfunction and decreased expression of glucose transporter (GLUT4) were identified as main factors of insulin resistance.

Moderate physical exercise attenuates the alterations of feeding behaviour induced by social stress in female rats.

Epidemiological studies have demonstrated that stress-related disorders, such as the increase on the caloric intake, are twice as common in women as in men, but surprisingly, very few studies have been tested this subject on female experimental animals. Additionally, it has been proposed that regular physical exercise can improve the deleterious effects of stress. Therefore, the present longitudinal study, performed in female rats, aimed to test the influence of chronic stress (ST) imposed by social isolation on the animals' caloric intake and to assess the effect of regular physical exercise of low intensity on this behaviour.
