Simplified, High Yielding Extraction of Xylan/Xylo-Oligosaccharides from : The Importance of the Algae Preservation Treatment.

The complex plant cell wall heteropolysaccharide xylan, and its breakdown products xylo-oligosaccharides and xylose, are value-added compounds with a plethora of potential applications in diverse areas. They are nonetheless currently poorly exploited, with a major bottleneck being the unavailability of efficient, low-cost, high-yield production processes. The major objective of the present study is to identify and characterise a high-yield process for the preparation of highly pure xylan/XOS products from the macroalga .

Chemical and Antioxidant Properties of Solvent and Enzyme-Assisted Extracts of and .

Extraction strategies impact the efficiency and nature of extracted compounds. This work assessed the chemical composition and antioxidant capacity of ethanolic, hydroethanolic, and aqueous versus enzyme-assisted extracts (isolated or with the sequential use of alcalase, cellulase, and viscozyme) of the macroalgae (brown, ) and (red, . For both macroalgae, enzyme-assisted extraction (EAE) was the most efficient process compared to solvent-assisted extraction (SAE), independent of solvent.

Enzymatic hydrolysis allows an integral valorization of Nannochloropsis oceanica resulting in the production of bioactive peptide extracts and an eicosapentaenoic acid enriched fraction.

Nannochloropsis oceanica is a microalga with relevant protein content, making it a potential source of bioactive peptides. Furthermore, it is also rich in fatty acids, with a special focus on eicosapentaenoic acid (EPA), an omega-3 fatty acid mainly obtained from marine animal sources, with high importance for human health. N.

Intrapulmonary Lung Sequestration.

A 16-year-old female, without relevant previous medical history, presented with 1 year episodic and progressive hemoptysis. CT scan revealed an abnormal blood supply from the descending thoracic aorta to the left lower lobe, the later presenting with significant signs of hyperperfusion. Therapy consisted of ligation of the anomalous vessel followed by left lower lobe lobectomy.

Raising Awareness on the Clinical and Forensic Aspects of Jellyfish Stings: A Worldwide Increasing Threat.

Jellyfish are ubiquitous animals registering a high and increasing number of contacts with humans in coastal areas. These encounters result in a multitude of symptoms, ranging from mild erythema to death. This work aims to review the state-of-the-art regarding pathophysiology, diagnosis, treatment, and relevant clinical and forensic aspects of jellyfish stings.

Extracts as Modulators of the Health Status and the Inflammatory Response of Gilthead Seabream Juveniles ().

This study aimed to evaluate the effects of short-term supplementation, with 2% () biomass and two 0.1% extracts, on the health status (experiment one) and on the inflammatory response (experiment two) of gilthead seabream (). The trial comprised four isoproteic (50% crude protein) and isolipidic (17% crude fat) diets.

Membrane fractionation of Cynara cardunculus swine blood hydrolysate: Ingredients of high nutritional and nutraceutical value.

This work proposes an innovative approach to valorise swine blood based on enzymatic hydrolysis and membrane fractionations. Hydrolysis with Cynara cardunculus enzymes, followed by microfiltration and double nanofiltration generated three high protein fractions, retentate of microfiltration (RMF; >0.5 µm) and retentate of nanofiltration (RNF; >3 kDa) with approximately 90% of protein on a dry basis and filtrate of nanofiltrate (FNF; <3 kDa) with 65%.

Bioactive Hydrolysates from : Optimal Process and Bioactive Properties.

Microalgae have been described as a source of bioactive compounds, such as peptides. Microalgae are easy to produce, making them a sustainable resource for extracting active ingredients for industrial applications. Several microalgae species have interesting protein content, such as with around 52.

Hydrolysate from Mussel Meat: Enzymatic Hydrolysis, Optimization and Bioactive Properties.

Mussel production generates losses and waste since their commercialisation must be aligned with target market criteria. Since mussels are rich in proteins, their meat can be explored as a source of bioactive hydrolysates. Thus, the main objective of this study was to establish the optimal production conditions through two Box-Behnken designs to produce, by enzymatic hydrolysis (using subtilisin and corolase), hydrolysates rich in proteins and with bioactive properties.
