Docosahexaenoic acid (DHA) is a vital structural component of neuronal tissue, which is critically required during pre- and post-natal brain development. Its liquid nature, fishy odor, poor bioavailability and oxidative stability are the major challenges in the development of a pharmaceutically elegant and stable formulation. In the present study, nanocapsules of DHA from microalgae oil were prepared using different combinations of wall materials (carbohydrates, polymers, gum and proteins). The encapsulation using spray drying was done to prepare a pharmaceutically stable DHA formulation...

The effect of chitosan decoration on the transport of epigallocatechin (EGC)-encapsulated ferritin cage across the Caco-2 cells was investigated. After the encapsulation of EGC in apo-red bean (adzuki) ferritin (apoRBF), the EGC-loaded apoRBF nanoparticle (ER) was fabricated with an encapsulation ratio of 11.6% (w/w). The results indicated that different chitosan molecules (with molecular weights of 980, 4600, 46 000, and 210 000 Da) could attach onto the apoRBF via electrostatic interactions to form ER-chitosan complexes (ERCs) (ERCs980 , ERCs4600 , ERCs46000 , and ERCs210000 )...

Age-related macular degeneration (AMD) is among the increasing number of diseases causing irreversible blindness in the elderly. Dry AMD is characterized by the accumulation of lipofuscin in retinal pigment epithelium (RPE) cells. N-Retinylidene-N-retinylethanolamine (A2E), a component of lipofuscin, is oxidized to oxo-A2E under blue light illumination, leading to retinal cell death. The aim of this study was to investigate the protective effect and mechanism of quercetin-3-O-α-l-arabinopyranoside (QA) against blue light (BL)-induced damage in both RPE cells and mice models...

Geranium molle L., commonly known as Dove's-foot Crane's-bill or Dovesfoot Geranium, is an herbaceous plant belonging to the Geraniaceae family. Contrary to many other Geranium species, the bioactivity and the phytochemical composition of G. molle seem not to have attracted attention until a recent study from our group regarding the bioactivity of several aqueous and organic extracts of the plant. In particular, we assessed the cytotoxic activity of these extracts against several human tumor cell lines (breast, lung, cervical and hepatocellular carcinomas) and a non-tumor porcine liver primary cell line, inspired by an ethnopharmacological report describing the traditional use of this medicinal plant in some regions of Northeast Portugal for the treatment of cancer...

A growing body of evidence indicates that inflammation is associated with tumorigenesis, metastasis and chemotherapeutic resistance in patients with colorectal cancer (CRC). Natural flavonoids are promising agents for inflammation-related tumor progression in patients with CRC. This study aimed to assess the efficacy of flavonoid fisetin supplementation on the inflammatory status and matrix metalloproteinase (MMP) levels in these patients. In this double-blind, randomized placebo-controlled clinical trial, 37 CRC patients undergoing chemotherapy were assigned to receive either 100 mg fisetin (n = 18) or placebo (n = 19) for seven consecutive weeks...

Abundant studies have highlighted the protective effects of docosahexaenoic acid (DHA), in the form of glycerolipids (glycerophosphatides and triglycerides) and DHA-ethyl esters (DHA-EE) in Alzheimer's disease (AD); however, eicosapentaenoic acid (EPA) has rarely been implicated. In the present study, we compared the effects of dietary EPA in the form of phosphatidylcholine (EPA-PC) and EE with DHA-EE (DHA/EPA = 60 mg kg-1 d-1 , i.g., 20 days) on cognitive deficits in AD rats. EPA-PC, rather than EPA-EE, significantly improved Aβ-induced cognitive impairment and has a comparable effect with DHA-EE...

Phenolic acids have been reported to play a role on the antioxidant activity and other important biological activities. However, as most polyphenolics in food products are either bound to cellular matrices or present as free polymeric forms, the way they are absorbed has not been totally clear until now. Hydrolytic enzymes may act to increase functionalities in polyphenolic-rich foods, enhancing the bioaccessibility of phenolic compounds and minerals from whole grains. The aim of this study was to evaluate the action of tannin acyl hydrolase (tannase) on the total phenols, phenolic acid profile, antioxidant capacity and in vitro bioaccessibility of phenolic acids found in whole rye flour (RF)...

Cereal grains and grain pulses are primary staples often consumed together, and contribute a major portion of daily human calorie and protein intake globally. Protective effects of consuming whole grain cereals and grain pulses against various inflammation-related chronic diseases are well documented. However, potential benefits of combined intake of whole cereals and pulses beyond their complementary amino acid nutrition is rarely considered in literature. There is ample evidence that key bioactive components of whole grain cereals and pulses are structurally different and thus may be optimized to provide synergistic/complementary health benefits...

A cationic peroxidase (POD) was purified from proso millet seeds (PmPOD) using ammonium sulfate fractionation, cation exchange, and size exclusion chromatography. The purified PmPOD showed toxicity to normal cells and tumor cells, but was more sensitive in HT29 cells. Furthermore, the mechanism driving HCT116 and HT29 cell death by PmPOD was the induction of receptor interacting protein kinase 1 (RIPK1)- and RIPK3-dependent necroptosis, independent of apoptosis. More importantly, PmPOD could induce tumor necrosis factor-α (TNF-α) production through transcriptional upregulation...

Curcumin is a bioactive phytochemical that can be utilized as a nutraceutical or pharmaceutical in functional foods, supplements, and medicines. However, the application of curcumin as a nutraceutical in commercial food and beverage products is currently limited by its low water-solubility, chemical instability, and poor oral bioavailability. In this study, all-natural colloidal delivery systems were developed to overcome these challenges, which consisted of saponin-coated curcumin nanoparticles formed using a pH-driven loading method...

The current cancer treatment scenario lacks drugs acting as both radiosensitizer and radioprotector agents. In this context, the radiomodulatory properties exerted by an aqueous extract from the fruits of the Italian Prunus avium cv. Della Recca (PaDRw) were investigated. The extract, obtained through an environmentally-friendly ultrasound-assisted extraction, seemed to act as a radioprotector at lower tested doses (25 and 50 μg mL-1 ) and a radiosensitizer at 400 and 500 μg mL-1 dose levels towards the neuroblastoma SH-SY5Y cell line, irradiated with four graded X-ray doses (0, 0...

This study aimed to better understand the functional properties of ribose and 20 amino acid Maillard reaction products (MRPs). The ABTS+ radical scavenging ability of the ribose-20 amino acid MRPs was evaluated. Among the MRPs, ribose-histidine MRPs (RH-MRPs) showed the highest inhibitory activities on the ABTS+ radical scavenging ability, aldose reductase (AR), and tyrosinase compared to other MRPs. Functional compounds with antioxidant and AR inhibitory activities have been recognized as an important strategy in the prevention and treatment of diabetic complications, and the search for tyrosinase inhibitors is important for the treatment of hyperpigmentation, development of skin-whitening agents, and use as preservatives in the food industry...

In vivo studies measuring true fractional calcium (Ca) absorption have shown that dietary fat is a significant predictor of absorption and is influenced by luminal pH levels. However, whether changes in Ca bioaccessibility (CaB) can explain the effects on absorption has not been examined. In the current study, we examined two high fat diets enriched in either monounsaturated fatty acids or saturated fatty acids (SFA), and a low-fat diet (LFD), each with 50 mg Ca, and measured CaB at different intestinal regions during normal acidic or higher (pH = 7) gastrointestinal conditions using an in vitro gastrointestinal model...
