Decarbonizing the Transport of Microalgae-based Products - The Role of E-mobility.

Background: The decarbonization of road transport is a precondition for achieving carbon neutrality. Battery-electric vehicle technology can make this a reality. In this bias, the objective of the article is to shed light on the ongoing debate about the potentially important role of the adoption of electric vehicles in the transport of microalgae- based products to help them advance to a cleaner life cycle.

The Role of Light on the Microalgae Biotechnology: Fundamentals, Technological Approaches, and Sustainability Issues.

Light energy directly affects microalgae growth and productivity. Microalgae in natural environments receive light through solar fluxes, and their duration and distribution are highly variable over time. Consequently, microalgae must adjust their photosynthetic processes to avoid photo limitation and photoinhibition and maximize yield.

Bioactive Polysaccharides from Microalgae: A Close Look at the Biomedical Applications.

There is a current tendency towards bioactive natural products that can be used in different areas such as food, pharmaceutical, and biomedical. In the last decades, polysaccharides have attracted increasing interest because of their potent nontoxic effects, therapeutic properties, and diversified range of applications. Polysaccharides are complex and heterogeneous macromolecules constituted of different monosaccharides and, in some cases, of glucuronic acid and sulphate groups.

Microalgae-derived polysaccharides: Potential building blocks for biomedical applications.

In recent years, the increasing concern about human health well-being has strongly boosted the search for natural alternatives that can be used in different fields, especially in biomedicine. This has put microalgae-based products in evidence since they contain many bioactive compounds, of which polysaccharides are attractive due to the diverse physicochemical properties and new or improved biological roles they play. Polysaccharides from microalgae, specially exopolysaccharides, are critically important for market purposes because they can be used as anti-inflammatory, immunomodulatory, anti-glycemic, antitumor, antioxidant, anticoagulant, antilipidemic, antiviral, antibacterial, and antifungal agents.

Energy Expenditure in Older Adults Who Are Frail: A Doubly Labeled Water Study.

Background And Purpose: Frailty is a common and important geriatric syndrome, distinct from any single chronic disease, and an independent predictor of mortality. It is characterized by age-associated decline in physiological reserve and function across multiple systems, culminating in a vicious cycle of altered energy expenditure. The total energy expenditure (TEE) of an individual includes the resting metabolic rate (RMR), the thermic effect of feeding, and the energy expenditure in physical activity (PAEE).

Effects of aerobic exercise on functional capacity, anthropometric measurements and inflammatory markers in diabetic elderly women.

This study investigated the effects of an aerobic training program on functional capacity [Timed Up and Go test (TUG), timed 10-m walk test (10MWT), five-repetition sit-to-stand test (5-STS), handgrip strength test (HGS) and one-legged stance test (OLS)], anthropometric measurements [body mass, body mass index (BMI), waist and hip circumferences and waist-to-hip ratio] and plasma levels of inflammatory markers [soluble tumor necrosis factor receptors 1 and 2, and interleukins 6 and 10] in 43 elderly women with type 2 diabetes mellitus.
