Supplementation in In Vitro Tissue Culture Techniques
The growing demand for native planting material in ecological restoration and rehabilitation for agro-silvo-pastoral ecosystems has resulted in a major global industry in their sourcing, multiplication, and sale. Plant tissue culture is used for producing high-quality, disease-free, and true-to-type plants at a fast rate. Micropropagation can help to meet the increasing demand for planting material and afforestation programs.

Superoxide Radical Anion O2•−
Classically, superoxide anion O2•− and reactive oxygen species ROS play a dual role. At the physiological balance level, they are a by-product of O2 reduction, necessary for cell signalling, and at the pathological level they are considered harmful, as they can induce disease and apoptosis, necrosis, ferroptosis, pyroptosis and autophagic cell death.

Superoxide Dismutases
Several enzymes exist that can convert or degrade reactive oxygen species (ROS); among them are the superoxide dismutases (SODs). SODs are responsible for converting superoxide anions to hydrogen peroxide by dismutation, therefore participating in the ROS detoxification. Here a short overview on the role of SODs in development and pathogenicity of fungi like Podospora anserina and Aspergillus spp. is given.

Superoxide Dismutase 1 in Amyotrophic Lateral Sclerosis
Amyotrophic Lateral Sclerosis (ALS) is a progressive motor neurodegenerative disease. Cell damage in ALS is the result of many different, largely unknown, pathogenetic mechanisms. Superoxide Dismutase 1 (SOD1) physiologically mediates intracellular peroxide generation. About 10% of ALS subjects show a familial disease associated with different gain-of-function SOD1 mutations. The occurrence of sporadic ALS, not clearly associated with SOD1 defects, has been also described. SOD1-dependent pathways have been involved in neuron functional network as well as in immune-response regulation.

Superficial Heat Therapy
Low back pain (LBP) is an exceptionally common musculoskeletal problem and a leading cause of disability. LBP is experienced by most adults at some stage of their life, with an estimated 577 million people affected in 2017. A recent systematic literature review stated that the prevalence of LBP ranges from 1.4% to 20.0%, and the incidence from 0.024% to 7.0%. The review focused on the application and effect of mild superficial heat for musculoskeletal pain, especially back pain. The review was able to show that the application of mild heat is easily applicable and effective when indicated.

Supercritical Fluids for the Encapsulation
Encapsulation based on supercritical fluids has shown several advantages as green technology for the production of functional ingredients with enhanced stability and tailored protection from environmental factors. Thanks to the inherent absence of organic solvent, the low temperature of the process to reach the supercritical state and the capacity to dissolve lipid soluble bioactives, it allows obtaining functional ingredient easily designed to tailor the controlled release of the bioactive, or to reach specific levels of taste, odor and color. The present entry aims to highlight the pros and cons of the encapsulation techniques based on supercritical fluids giving emphasis to their innovative aspects that could be of interest to the food industry.

Superabsorbent Polymers
Natural strategies for protecting the environment as well as plant, animal and human health is considered one of the main goals of developed countries. Recently, the use of absorbent polymers and hydrogel in agriculture has demonstrated several benefits for soil amendments, saving water content, reducing the consumption of soil nutrients, minimizing the negative impacts of dehydration and moisture stress in crops and controlling several phytopathogens.

suPAR in Autoimmune Rheumatic Diseases
The soluble urokinase plasminogen activator receptor (suPAR) is the bioactive form of urokinase plasminogen activator receptor (uPAR), a membrane-bound glycoprotein, and it is primarily expressed on the surface of immunologically active cells. Mirroring local inflammation and immune activation, suPAR has gained interest as a potential prognostic biomarker in several inflammatory diseases. Mirroring immune system activation, suPAR has been associated with many autoimmune rheumatic diseases.

SUOX Gene
Sulfite oxidase: The SUOX gene provides instructions for making an enzyme called sulfite oxidase, which helps break down protein building blocks (amino acids) that contain sulfur when they are no longer needed.
