Plant sterols and stanols (PS) are natural, non-nutritive molecules that play a structural role in plant membranes similar to that of cholesterol in animal membranes and abound in seeds and derived oils. PS exert their physical effect of interference with micellar solubilization of cholesterol within the intestinal lumen and are marginally absorbed by enterocytes, with negiglible increases in circulating levels. The physiological role of PS in plants and their natural origin and non-systemic action, together with their cholesterol-lowering effect, make them an attractive option as non-pharmacological agents for the management of hypercholesterolemia...

The central nervous system (CNS) is the most cholesterol-rich organ in mammals. Cholesterol homeostasis is essential for proper brain functioning and dysregulation of cholesterol metabolism can lead to neurological problems. Multiple sclerosis (MS) and Alzheimer's disease (AD) are examples of neurological diseases that are characterized by a disturbed cholesterol metabolism. Phytosterols (PS) are plant-derived components that structurally and functionally resemble cholesterol. PS are known for their cholesterol-lowering properties...

Influenza viruses are severe human pathogens that pose persistent threat to public health. Each year more people die of influenza virus infection than that of breast cancer. Due to the limited efficacy associated with current influenza vaccines, as well as emerging drug resistance from small molecule antiviral drugs, there is a clear need to develop new antivirals with novel mechanisms of action. The influenza virus polymerase complex has become a promising target for the development of the next-generation of antivirals for several reasons...

Epigenetics control the expression of genes and is responsible for the cellular phenotypes. The fundamental basis of these mechanisms involves in part the post-translational modifications (PTMs) of DNA and proteins, in particular the nuclear histones. DNA can be methylated or demethylated on cytosine. Histones are marked by several modifications including acetylation and/or methylation, and of particular importance are the covalent modifications of lysine. It exists a balance between addition and removal of these PTMs, leading to three groups of enzymes involved in these processes: the writers adding marks, the erasers removing them, and the readers able to detect these marks and participating in the recruitment of transcription factors...

Flavonoids are phenolic compounds widely distributed in the human diet. Their intake has been associated with a decreased risk of different diseases such as cancer, immune dysfunction or coronary heart disease. However, the knowledge about the mechanisms behind their in vivo activity is limited and still under discussion. For years, their bioactivity was associated with the direct antioxidant and radical scavenging properties of phenolic compounds, but nowadays this assumption is unlikely to explain their putative health effects, or at least to be the only explanation for them...

Cancer-related cachexia (CAC) is a syndrome occurring in many cancer patients, with a detrimental effect on their survival. Recent reports have outlined that the syndrome may be partly explained by the deleterious and pro-inflammatory action of reactive oxygen species (ROS). This review focuses on nutrients that theoretically could counteract the oxidative stress in tumor cells, fundamentally due to their antioxidant activity. The preclinical and clinical results obtained with the nutritional elements selenium, melatonin, taurine, carnosine, coenzyme Q10 (ubiquinone), and omega-3 polyunsaturated fatty acids (PUFA's) are discussed in the light of the pathophysiology of CAC...

Radioembolization (RE) is a valuable treatment for liver cancer. It consists of administering radioactive microspheres via an intra-arterially placed catheter with the aim of lodging these microspheres, which are driven by the bloodstream, in the tumoral bed. Even though it is a safe treatment, some radiation-induced complications may arise. In trying to detect or solve the possible incidences that cause nontarget irradiation, simulating the particle-hemodynamics in hepatic arteries during RE via computational fluid dynamics (CFD) tools has become a valuable approach...

Besides the well-characterized effect of foods and supplements enriched with plant sterols/stanols on serum LDL-C concentrations, evidence is now emerging that phytosterols exert beneficial effects on non-lipid variables such as inflammatory and oxidative stress markers, coagulation parameters and endothelial function. This makes sterols and stanols an attractive alternative for dietary interventions in cardiovascular disease prevention, particularly in populations at low or medium risk. This review aims to summarize the current knowledge derived from experimental studies and human data on the anti-inflammatory effects of phytosterols/stanols and their relevance in promoting atheroprotection and preventing cardiovascular disease...

BACKGROUND: Irinotecan (IRI) is a widely used chemotherapeutic drug, mostly used for first-line treatment of colorectal and pancreatic cancer. IRI doses are usually established based on patient's body surface area, an approach associated with large inter-individual variability in drug exposure and high incidence of severe toxicity. Toxic and therapeutic effects of IRI are also due to its active metabolite SN-38, reported to be up to 100 times more cytotoxic than IRI. SN-38 is detoxified by the formation of SN-38 glucuronide, through UGT1A1...
