BACKGROUND: Nowadays, nanoparticles are of great interest for the industry due to their numerous possible applications in several fields. Research on this topic seeks to develop many procedures to produce nanoparticles, mostly at lab scale, batch-wise and with low yield. These procedures generally do not suit industrial needs of continuous, high capacity production. Moreover, the product characteristics require targeting narrow particle size distributions and high quality, which is difficult to achieve by traditional equipment...

Fats are essential nutrients that have a significant role in the human diet and are essential to provide energy. Fatty acids are present in several types of lipids, such as triglycerides and phospholipids. Fatty acids differ among them, depending on the number of double bonds and on the length of the hydrocarbon chains. If there are no double bonds, the fatty acids are considered saturated and show a linear structure. Compounds with double bonds are unsaturated and have bent structure. The saturated fatty acids are usually solid at room temperature and the unsaturated fatty acids are liquid at that very same temperature...

The human gastrointestinal tract is exposed to a variety of toxic agents, such as Helicobacter pylori (H.pylori), nonsteroidal anti-inflammatory drugs (NSAIDs), gastric acid, enteric pathogenic bacteria, excessive auto immune reactions, and chronic mental stresses. These stressors generate free radicals within the gastrointestinal tissues, causing chronic inflammatory diseases, ulcers, cancers, and functional disturbances. Recent studies have demonstrated that some natural food compounds upregulate the nuclear factor erythroid 2-related factor 2-mediated antioxidant system, ameliorating or preventing these disorders...

BACKGROUND: Physical activity can be involved in the prevention of gastrointestinal (GI)-tract diseases, however, the results regarding the volume and the intensity of exercise considered as beneficial for protection of gastrointestinal organs are conflicting. AIMS AND METHODS: The main objective of this review is to provide a comprehensive and updated overview on the beneficial and harmful effects of physical activity on the gastrointestinal tract. We attempted to discuss recent evidence regarding the association between different modes and intensity levels of exercise and physiological functions of the gut and gut pathology...

Nasopharyngeal cancer (NPC) is a rare type of head and neck cancer that is mainly treated by radiotherapy, but sometimes it is radioresistant. Curcumin is a polyphenolic natural product with established anti-cancer effects in various human cancers. Recent studies have shown that curcumin has therapeutic and radio-sensitizing effects on NPC cells. In fact, it has been found that curcumin can sensitize NPC cells to radiation through different mechanisms, including modulation of ROS generation, Jab1/CSN5 and non-coding RNAs...

Hydroxytyrosol (HT) and its derivatives represent the minor components of virgin olive oil (VOO) that are of great interest for their pharmacological properties and among the most widely researched natural antioxidant compounds. In this review, the occurrence and metabolic fate of HT and its precursors are presented prior to discussing its beneficial effects on health. Bioavailability studies show that the metabolites detected in plasma depend on the model used (animal or human), the HT source (simple molecule or complex precursors) and the dose administered...

Curcumin quite possibly represents one of the most diverse therapeutic agents yet isolated from natural sources. Therapeutic benefits of this extraordinary natural compound have been demonstrated during treatment of a variety of diseases, including cancer, inflammatory processes, immunological disorders, diabetes, and oxidative stress often associated with hyperlipidemia. Due to its unique molecular chemical structure and functional groups, curcumin may bind with and subsequently either inhibit or activate a variety of endogenous biomolecules, including enzymes, receptors, signaling molecules, metals, transcription factors, and even certain proteins located in cell membranes...

Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide, leading to the second most likely cause of cancer-related deaths. Medical imaging is crucial in clinic for HCC screening and diagnosis. Due to the relatively high special resolution and excellent sensitivity, magnetic resonance imaging (MRI) by using magnetic nanoparticle-based contrast agents has been used so far in HCC imaging and staging, demonstrating great potential and promising in vivo applications. This review focuses on the use of different magnetic nanoparticles for construction of HCC nanoprobes for MR imaging and theranostic purpose...

The pancreas, the salivary glands and the dental enamel producing ameloblasts have marked developmental, structural and functional similarities. One of the most striking similarities is their bicarbonate-rich secretory product serving acid neutralization. An important difference between them is that while pancreatic juice and saliva are delivered into a lumen where they can be collected and analyzed, ameloblasts produce locally precipitating hydroxyapatite which cannot be easily studied. Interestingly, the ion and protein secretion by the pancreas, the salivary glands, and maturation ameloblasts are all two-step processes, of course with significant differences too...

Polyphenols constitute a group of compounds that have been highly investigated for their beneficial effects against various pathologic and non-pathologic conditions and diseases. Among their multi-faceted properties, their anti-oxidant potential nominates them as ideal protective candidates for conditions characterized by elevated levels of oxidative stress, including aging and age-related diseases. The nematode Caenorhabditis elegans is a multicellular model organism that is highly exploited in studies related to aging and age-associated diseases...

INTRODUCTION: Although a great many strategies have been proposed for tumor-targeted chemotherapy, current delivery methods of anticancer drugs present limited success with inevitable systemic toxicity. The aim of this study was to develop a new kind of theranostic carrier for targeted tumor therapy. METHODS: Prior to prepare CHC-PFP-DOX, carboxymethyl-hexanoyl chitosan (CHC) was synthesized by acylation of carboxymethyl chitosan. To develop CHC-PFP, perfluoropentane (PFP), an ultrasound gas precursor, were simultaneously encapsulated into the hydrophobic inner cores of pre-formulated CHC micelle in aqueous phase via using the oil in water (O/W) emulsion method...
