Nutraceutical Approaches to Dyslipidaemia: The Main Formulative Issues Preventing Efficacy

Currently, the nutraceutical approach to treat dyslipidaemia is increasing in use, and in many cases is used by physicians as the first choice in the treatment of patients with borderline values. Nutraceuticals represent an excellent opportunity to treat the preliminary conditions not yet showing the pathological signs of dyslipidaemia. Their general safety, the patient's confidence, the convincing proof of efficacy and the reasonable costs prompted the market of new preparations. Despite this premise, many nutraceutical products are poorly formulated and do not meet the minimum requirements to ensure efficacy in normalizing blood lipid profiles, promoting cardiovascular protection, and normalizing disorders of glycemic metabolism. In this context, bioaccessibility and bioavailability of the active compounds is a crucial issue. Little attention is paid to the proper formulations needed to improve the overall bioavailability of the active molecules. According to these data, many products prove to be insufficient to ensure full enteric absorption. The present review analysed the literature in the field of nutraceuticals for the treatment of dyslipidemia, focusing on resveratrol, red yeast rice, berberine, and plant sterols, which are among the nutraceuticals with the greatest formulation problems, highlighting bioavailability and the most suitable formulations.

Should We Aim to Create a Perfect Healthy Utopia? Discussions of Ethical Issues Surrounding the World of Project Itoh's Harmony

To consider whether or not we should aim to create a perfect healthy utopia on Earth, we focus on the SF novel Harmony (2008), written by Japanese writer Project Ito, and analyze various issues in the world established in the novel from a bioethical standpoint. In the world depicted in Harmony, preserving health and life is a top priority. Super-medicine is realized through highly advanced medical technologies. Citizens in Harmony are required to strictly control themselves to achieve perfect health and must always disclose their health information to the public and continuously prove their health. From a bioethical standpoint, the world in Harmony is governed by a "healthy longevity supremacy" principle, with being healthy equated to being good and right. Privacy no longer exists, as it is perceived ethical for citizens to openly communicate health-related information to establish one's credibility. Moreover, there is no room for self-determination concerning healthcare because medical interventions and care are completely routinized, automated, centralized, and instantly provided. This is a situation where the community exhibits extremely powerful and effective paternalism. One can argue that healthy longevity is highly preferred. But is it right to aim for a perfectly healthy society at all costs? Should we sacrifice freedom, privacy, vivid feelings, and personal dignity to achieve such a world? In our view, the answer is no, as this would require the loss of many essential values. We conclude by proposing an alternative governing principle for future healthcare, and refer to it as the "do-everything-in-moderation" principle.

Characteristics, Biological Properties and Analytical Methods of Trans-Resveratrol: A Review

Trans-resveratrol (TR) is the biological active isomer of resveratrol and the one responsible for therapeutic effects; both molecules are non-flavonoid phenolics of the stilbenes class found mainly in berries and red grapes. TR biological properties lie in modulation of various enzymatic classes. It is a promising candidate to novel drugs due its applications in pharmaceutical and cosmetic industries, such as anticarcinogenic, antidiabetic, antiacne, antioxidant, anti-inflammatory, neuroprotective, and photoprotector agent. It has effects on bone metabolism, gastrointestinal tract, eyes, kidneys, and in obesity treatment as well. Nevertheless, its low solubility in water and other polar solvents may be a hindrance to its therapeutic effects. Various strategies been developed to overcome these issues, such as the drug delivery systems. The present study performed a research about methods to identify TR and RESV in several samples (raw materials, wines, food supplements, drug delivery systems, and blood plasma). Most of the studies tend to analyze TR and RESV by high performance liquid chromatography (HPLC) coupled with different detectors, even so, there are reports of the use of capillary electrophoresis, electron spin resonance, gas chromatography, near-infrared luminescence, UV-Vis spectrophotometer, and vibrational spectrophotometry, for this purpose. Thus, the review evaluates the biological activity of TR and demonstrates the currently used analytical methods for its quantification in different matrices.
