Resveratrol regulates inflammation and improves oxidative stress via Nrf2 signaling pathway: Therapeutic and biotechnological prospects.

Usually, in aerobic metabolism, natural materials including nucleic acids, proteins, and lipids can experience auxiliary injury by oxidative responses. This damage produced by reactive oxygen/nitrogen species has been identified as "oxidative stress." As a natural polyphenol got from red wine and peanuts, resveratrol is one of the most eminent anti-aging mixtures. Based on many studies', resveratrol hinders destructive effects of inflammatory causes and reactive oxygen radicals in several tissues. The nuclear erythroid 2-related factor 2 is a factor related to transcription with anti-inflammatory, antioxidant possessions which is complicated by enzyme biotransformation and biosynthesis of lipids and carbohydrates. This review provides current understanding and information about the character of resveratrol against oxidative stress and regulation of inflammation via Nrf2 signaling pathway.

Tissue Engineering Challenges for Cultivated Meat to Meet the Real Demand of a Global Market.

Cultivated meat (CM) technology has the potential to disrupt the food industry-indeed, it is already an inevitable reality. This new technology is an alternative to solve the environmental, health and ethical issues associated with the demand for meat products. The global market longs for biotechnological improvements for the CM production chain. CM, also known as cultured, cell-based, lab-grown, in vitro or clean meat, is obtained through cellular agriculture, which is based on applying tissue engineering principles. In practice, it is first necessary to choose the best cell source and type, and then to furnish the necessary nutrients, growth factors and signalling molecules via cultivation media. This procedure occurs in a controlled environment that provides the surfaces necessary for anchor-dependent cells and offers microcarriers and scaffolds that favour the three-dimensional (3D) organisation of multiple cell types. In this review, we discuss relevant information to CM production, including the cultivation process, cell sources, medium requirements, the main obstacles to CM production (consumer acceptance, scalability, safety and reproducibility), the technological aspects of 3D models (biomaterials, microcarriers and scaffolds) and assembly methods (cell layering, spinning and 3D bioprinting). We also provide an outlook on the global CM market. Our review brings a broad overview of the CM field, providing an update for everyone interested in the topic, which is especially important because CM is a multidisciplinary technology.

Biotechnological Applications and Health-Promoting Properties of Flavonols: An Updated View.

Flavonols are a subclass of natural flavonoids characterized by a remarkable number of biotechnological applications and health-promoting properties. They attract researchers' attention due to many epidemiological studies supporting their usage. They are phytochemicals commonly present in our diet, being ubiquitous in the plant kingdom and, in particular, relatively very abundant in fruits and vegetables. All these aspects make flavonols candidates of choice for the valorization of products, based on the presence of a remarkable number of different chemical structures, each one characterized by specific chemical features capable of influencing biological targets inside the living organisms in very different manners. In this review, we analyzed the biochemical and physiological characteristics of flavonols focalizing our attention on the most promising compounds to shed some light on their increasing utilization in biotechnological applications in processing industries, as well as their suitable employment to improve the overall wellness of the humankind.

Identifying and Averting the Difficulties in Converting Biotechnological Innovations into Successful Commerce: Case of Bahrain

The purpose of this study is to examine the difficulties encountered by Bahraini entrepreneurs in converting innovative ideas in the biotechnology field to a profitable trade. Methodology - The study applies a qualitative approach. Semistructured, one-to-one interviews with four managers have been done to identify the obstacles they faced. Findings - Initial results prove that some factors, including funding, workforce skills, government regulations, and the Bahraini market environment, significantly affect success in the biotechnology industry. Further analysis suggests that the Bahraini market environment is the more fundamental obstacle compared to the others. Two additional factors, namely time management and infrastructure, have an insignificant effect on Bahrain’s progress in the biotech industry. Practical implications - This study is targeted at regulatory bodies in Bahrain and entrepreneurs to assist them in pinpointing the obstacles faced in the biotech industry and address them subsequently. Originality– This research contributes to innovative entrepreneurship literature relating to the biotech industry in the Gulf Cooperation Council (GCC) countries, primarily in Bahrain. As the 2030 vision for Bahrain depends on diversification of income sources, it is interesting to examine the difficulties that challenge entrepreneurs once they try to convert innovative ideas in the field of biotechnology into a successful trade story. Recommendation - improving the workforce skills to be competitive in the market with current impacts of the COVID-19 pandemic and validating these results quantitively are recommended. © 2020, Arabian Gulf University.

Recent Findings in Azaphilone Pigments.

Filamentous fungi are known to biosynthesize an extraordinary range of azaphilones pigments with structural diversity and advantages over vegetal-derived colored natural products such agile and simple cultivation in the lab, acceptance of low-cost substrates, speed yield improvement, and ease of downstream processing. Modern genetic engineering allows industrial production, providing pigments with higher thermostability, water-solubility, and promising bioactivities combined with ecological functions. This review, covering the literature from 2020 onwards, focuses on the state-of-the-art of azaphilone dyes, the global market scenario, new compounds isolated in the period with respective biological activities, and biosynthetic pathways. Furthermore, we discussed the innovations of azaphilone cultivation and extraction techniques, as well as in yield improvement and scale-up. Potential applications in the food, cosmetic, pharmaceutical, and textile industries were also explored.
