Nutraceuticals in migraine treatment

Migraineurs experience significant decline in functioning and productivity, which in turn translates into diminished quality of life and a major economic burden on society at large [1]. Although current research has better elucidated the pathophysiology underlying migraine, the exact etiology remains to be defined. Biochemical factors that could potentially disrupt the vascular endothelial function, leading to cortical spreading depression that can activate and affect the trigeminovascular system, are primary candidates for involvement in migraine pathophysiology [2]. The current mechanisms explaining the pathogenesis behind migraine continue to evolve, but theories of variability in cortical excitability, neuronal dysregulation and neurotransmitter/receptor activation are all important and potentially amenable to nutraceutical manipulation [3]. As our knowledge about migraine pathogenesis expands, our current understanding of the complex relationships between pharmacological doses, cofactor and hormone interactions, and neural and pain pathway activities will also advance, creating new avenues for research and migraine treatment development [3].

Tannin containing legumes as a model for nutraceuticals against digestive parasites in livestock

Parasitic infections with gastrointestinal nematodes (GINs) still represent a worldwide major pathological threat associated with the outdoor production of various livestock species. Because of the widespread resistance to synthetic chemical anthelmintics, there is a strong impetus to explore novel approaches for a more integrated management of the infections. The use of nutraceuticals in the control of GINs is one of the alternatives which has been widely studied for since 20 years. The objectives of this review are: i) to define and illustrate the concept of ‘nutraceutical’ in the context of veterinary parasitology based on data obtained on the most studied GIN models in small ruminants, the tannin-containing legumes (Fabaceae); ii) to illustrate how the ‘nutraceutical concept’ could be expanded to other plants, other livestock production systems and other GI parasitic diseases, and iii) to explain how this concept is opening up new research fields for better understanding the interactions between the host, the digestive parasites and the environment.

Marine nutraceuticals : glucosomine and omega-3 fatty acids : new trends for established ingredients

Glucosamine and long-chain omega-3 lipid are the two most widely consumed marine nutracuticals. These   ingredients have been used as dietary supplement ingredients for many years, but  are now becoming important functional food and beverage ingredients. The production of GRAS and vegetarian glucosamine has led to increased use of this ingredient in beverages in particular. For long chain omega -3 lipid the development of stabilisation technologies has been critical for the increased use of these lipids in functional foods. The development of new sources of both of these ingredients, together with novel delivery and application technologies, will continue to drive increased consumption of these marine nutracuticals, in particular as functional food and beverage ingredients.

Global trends in marine nutraceuticals

An expanding body of scientific research indicates that the marine environment is emerging as a unique resource of functional food ingredients with health-promoting properties. Significant attention has been paid to exploration of potential nutraceuticals and pharmaceuticals derived from the ocean. Marine-based  nutraceuticals are gaining attention due to their unique features, which are absent in terrestrial-based resources. A number of new marine nutraceutical products have been introduced in the nutraceuticals and functional foods markets. The main sources and products of primary interest for marine nutraceuticals and ingredients include omega-3 fish/algal oil, phospholipids, micro/macro algal nutrition supplements, fish proteins and peptides, hydrolysates, shellfish chitin, fish collagen, and mineral supplements.

Anti-inflammatory and chondroprotectivity of dominant-negative survivan and nutraceuticals, lactoferrin and herbs

Osteoarthritis is a highly problematic and debilitating medical issues affecting over 630 million people worldwide. Current treatments include anti-inflammatory drugs and joint injections which are painful and cause systemic side effects. The present study, investigates the activity of nanoformulated bioactive proteins and herbals as potential therapeutics for chronic inflammatory arthritis.

Carotenoids and polyphenols in nutricosmetics, nutraceuticals, and cosmeceuticals

The market for cosmeceuticals continues with significant annual growth, but today consumers are more aware of nutritional products that contribute to both skin health and disease prevention. In the last 10 years, pharmacists, chemists, nutritionists, and physicians have been working together to develop new nutritional applications to satisfy peoples needs and demands. As a recent result of convergence phenomenon between cosmetics and food industries, nutricosmetics is a blurry area unfamiliar to many consumers and sometimes even to foods and cosmetics experts. Characterized by oral supplementation of nutrients, nutricosmetics are also known as beauty pills,beauty from within, and even oral cosmetics. The major claim is the antiaging effect, reducing wrinkles by fighting free radicals generated by solar radiation. Among the ingredients used in nutricosmetics, antioxidants represent the most crucial. The best-known antioxidants are carotenoids (beta-carotene, lycopene, lutein, zeaxanthin, and astaxanthin) and polyphenols (anthocyanidins, catechins, flavonoids, tannins, and procyanidins). This study presents an overview about the concept of nutricosmetics and gives us information about the difference between nutricosmetics, nutraceuticals, and cosmeceuticals. The article also discusses about carotenoids and polyphenols, two classes of ingredients often employed in such products.

Development of new therapeutic approaches in the treatments of Inflammatory Bowel Diseases: functional food and nutraceuticals vs synthetic peptides based vaccines

Inflammatory Bowel Diseases (IBD) are intestinal chronic relapsing diseases which ethiopathogenesis remains uncertain. Several group have attempted to study the role of factors involved such as genetic susceptibility, environmental factors such as smoke, diet, sex, immunological factors as well as the microbioma. None of the treatments available satisfy several criteria at the same time such as safety, long-term remission, histopatological healing, and specificity. We used two different approaches for the development of new therapeutic treatment for Inflammatory Bowel Disease. The first is focused on the understanding of the potential role of functional food and nutraceuticals nutrients in the treatment of IBD. To do so, we investigated the role of Curcuma longa in the treatment of chemical induced colitis in mice model. Since Curcma Longa has been investigated for its antinflammatory role related to the TNFα pathway as well investigators have reported few cases of patients with ulcerative colites treated with this herbs, we harbored the hypothesis of a role of Curcuma Longa in the treatment f IBD as well as we decided to assess its role in intestinal motility. The second part is based on an immunological approach to develop new drugs to induce suppression in Crohn’s disease or to induce mucosa immunity such as in colonrectal tumor. The main idea behind this approach is that we could manipulate relevant cell-cell interactions using synthetic peptides. We demonstrated the role of the unique interaction between molecules expressed on intestinal epithelial cells such as CD1d and CEACAM5 and on CD8+ T cells. In normal condition this interaction has a role for the expansion of the suppressor CD8+ T cells. Here, we characterized this interaction, we defined which are the epitope involved in the binding and we attempted to develop synthetic peptides from the N domain of CEACAM5 in order to manipulate it.

Stabilization of APIs and nutraceuticals through cocrystallization and molecular confinement

Cocrystallization of the molecule of interest could be a smart and dainty way to tune solubility properties of solid phases leaving the molecule chemically unchanged, hence it is widely investigated by companies and by solid state scientists. Despite of this extremely high interest towards cocrystallization no particular emphasis has been paid to using it as a means to stabilize liquid molecules. In this work we define a benchmark of relevant molecules for human health that have been combined with suitable partners according to crystal engineering methods in order to obtain cocrystals. Solubility properties in different solvents of cocrystals new solid phases have been tested and compared to the properties of the drugs. A further approach to deal with volatile compounds is molecular confinement inside molecular scaffold. Nowadays metal organic frameworks (MOFs) are studied in many fields ranging from catalysis to trapping or storage of gases, such as hydrogen, methane, CO2 thanks to their extremely high porosity. Our goal is to confine liquid guests of biological relevance inside MOF pores, monitoring via X-ray diffraction, spectroscopy and thermal analysis the stabilization of the molecule of interest inside the cavities.

Adjunctive nutraceuticals for depression: a systematic review and meta-analyses

OBJECTIVE: There is burgeoning interest in augmentation strategies for improving inadequate response to antidepressants. The adjunctive use of standardized pharmaceutical-grade nutrients, known as nutraceuticals, has the potential to modulate several neurochemical pathways implicated in depression. While many studies have been conducted in this area, to date no specialized systematic review (or meta-analysis) has been conducted. METHOD: A systematic search of PubMed, CINAHL, Cochrane Library, and Web of Science was conducted up to December 2015 for clinical trials using adjunctive nutrients for depression. Where sufficient data were available, a random-effects model analyzed the standard mean difference between treatment and placebo in the change from baseline to endpoint, combining the effect size data. Funnel plot and heterogeneity analyses were also performed. RESULTS: Primarily positive results were found for replicated studies testing S-adenosylmethionine (SAMe), methylfolate, omega-3 (primarily EPA or ethyl-EPA), and vitamin D, with positive isolated studies for creatine, folinic acid, and an amino acid combination. Mixed results were found for zinc, folic acid, vitamin C, and tryptophan, with nonsignificant results for inositol. No major adverse effects were noted in the studies (aside from minor digestive disturbance). A meta-analysis of adjunctive omega-3 versus placebo revealed a significant and moderate to strong effect in favor of omega-3. Conversely, a meta-analysis of folic acid revealed a nonsignificant difference from placebo. Marked study heterogeneity was found in a Higgins test for both omega-3 and folic acid studies; funnel plots also revealed asymmetry (reflecting potential study bias). CONCLUSIONS: Current evidence supports adjunctive use of SAMe, methylfolate, omega-3, and vitamin D with antidepressants to reduce depressive symptoms.
