Microalgae, while holding a significant promise for human nutrition, have seen only eleven species approved for consumption by the European Commission. Fifteen rarely examined microalgae strains, spanning two kingdoms, underwent screening for their nutritional profiles and potential impact on human health during two cultivation stages. Examination revealed the presence of protein, fiber, lipids, fatty acids, minerals, trace elements, and heavy metals, with their respective quantities documented. In the growth phase of microalgae, the concentration of arginine, histidine, ornithine, pure protein, crude protein, magnesium, manganese, iron, and zinc increased while the levels of nickel, molybdenum, and iodine decreased relative to the stationary phase. Chromista microalgae exhibited a greater content of total fat, C140, C141n5, C161n7, C204n6, C205n3, and As in comparison to plantae microalgae, a statistically significant result (p<0.005). In contrast, the subsequent samples exhibited elevated concentrations of C200, C201n9, and C183n3, along with increased levels of Ca and Pb (p < 0.005). In particular, the high concentration of nutrients like fibers, carotenoids, C20:6n3, magnesium, calcium, manganese, iron, selenium, zinc, nickel, molybdenum, and iodine in Chrysotila carterae suggested its potential as a valuable human food source. In short, a broad spectrum of nutrients can be found in microalgae, however, the specific composition varies across kingdoms, cultivation stages, and species.

The growth and development of the fetus and newborn throughout pregnancy and lactation are intrinsically linked to the mother's nutritional state, ultimately affecting the offspring's health. To ascertain the association between early-life n-3 polyunsaturated fatty acid deficiency and adult seizures, this experiment was conducted. N-3 PUFAs-deficient mice's offspring were started on -LNA diets, and additionally provided DHA-enriched ethyl esters and DHA-enriched phospholipid diets for 17 days, commencing at eight weeks of age. The animals were treated with intraperitoneal injections of pentylenetetrazol (PTZ) at 35 mg/kg dosage, every other day, for eight consecutive days during this period. Dietary deficiencies in n-3 PUFAs during early life, as demonstrated by the results, appear to amplify the severity of PTZ-induced epileptic seizures and consequent brain disorders. serum hepatitis Adult administration of n-3 PUFAs for 17 days demonstrably replenishes brain n-3 fatty acids, potentially lessening susceptibility to epilepsy and increasing seizure threshold by regulating neurotransmitter function, mitochondrial-mediated apoptosis, hippocampal demyelination, and neuroinflammation. The DHA-enriched phospholipid treatment proved more effective in reducing seizures than either -LNA or DHA-enriched ethyl ester treatments. Early-life dietary n-3 PUFA deficiency makes offspring more prone to PTZ-induced epilepsy as adults, and nutritional supplementation with these fatty acids increases tolerance for epileptic seizures.

This review article surveys past and current alginate-based materials within each application, demonstrating the expansive scope of alginate's development and adoption. The initial part spotlights the specific properties of alginates and where they are sourced. The second segment carefully aligns alginates, customizing the procedure based on application needs, characteristics, and limitations. Sodium alginate, a water-soluble form of the polysaccharide alginate, is a common occurrence. The substance, composed of hydrophilic and anionic polysaccharides, originates from natural brown algae and bacteria. Its capacity for gelling, retaining moisture, and creating a film makes it applicable in environmental protection, the cosmetics industry, medicine, the field of tissue engineering, and food processing. Comparing scientific articles focusing on alginate-based products in environmental protection, medicine, food, and cosmetics, a preponderance of studies was dedicated to environmental applications (30,767) and medicine (24,279), in contrast to the fewer publications found in the cosmetic (5,692) and food (24,334) sectors. In May 2023, the Google Scholar database served as the source for data, including the abstract, title, and keywords. Within this review, alginate-based materials are examined, presenting detailed information on modified composites and their potential practical implementations. Alginate's application in addressing water pollution and its significant monetary worth are highlighted. The present study contrasts existing knowledge, and its future trajectory is evaluated in this paper.

Microalgae have, throughout history, provided valuable compounds, primarily utilized as food sources and dietary supplements. Metabolites extracted from microalgae have recently become a vital component in the synthesis of various nanoparticles, providing an inexpensive and environmentally friendly alternative to chemical synthesis methods. Microalgae applications in medicine have become increasingly important, largely due to the occurrence of global health emergencies. This review assesses the effect of secondary metabolites produced by marine and freshwater microalgae and cyanobacteria on nanoparticle development, focusing on their therapeutic function. Subsequently, the deployment of independent compounds on the surfaces of nanoparticles for the purpose of alleviating diseases has also been addressed. While studies have shown the positive influence of high-value bioproducts on microalgae and their potential within the medical field, the precise way these bioproducts function in the human body and translating this scientific knowledge into clinical trials remain open questions.

The most severe form of asthma, characterized by concomitant obesity, poses a considerable challenge to management with currently available medications. 1-O-alkyl-glycerols (AGs), stemming from marine life and crucial for plasmalogen formation, display notable biological activity, thus positioning them as a significant candidate for pharmacological study. The objective of this study was to explore how Berryteuthis magister AGs influence lung capacity, fatty acid/plasmalogen composition, and cytokine/adipokine responses in obese individuals with asthma. A clinical trial of 19 patients exhibiting mild asthma combined with obesity involved a daily regimen of 0.4 grams of AGs for three months, in addition to their customary medical treatments. The evaluation of AGs' consequences was completed at one and three months of the treatment. Analysis of the study's results demonstrated that, after three months of AG supplementation, there was an elevation in FEV1 and FEV1/VC ratios, and a significant reduction in ACQ scores amongst 17 of the 19 patients. Ingestion of AGs led to amplified plasmalogen and n-3 PUFA concentrations in the blood, and an alteration in the synthesis and release of leptin and adiponectin by adipose tissue. AG supplementation diminished the presence of inflammatory cytokines (TNF-, IL-4, and IL-17a) and oxylipins (TXB2 and LTB4) in the plasma, indicating the anti-inflammatory potential of AGs. In essence, 1-O-alkyl-glycerols could be a potentially effective dietary supplement in enhancing pulmonary function and reducing inflammation in obese asthmatic individuals, and offering a natural means for the generation of plasmalogens. AG consumption, according to the study, initiated beneficial outcomes within one month, with an enhanced effect noted after three months of supplementation.

Starting materials D-xylonolactone and D-ribonolactone were utilized in the preparation of a series of five-membered bromolactones that exhibit structural correspondence with the mycalin A lactone's C1-C5 part. Employing HBr/AcOH for the bromination of D-ribonolactone, bypassing transesterification, this study uniquely explores the formation of the majority of the acetylated lactones for the first time. Wherever preparation was possible, both the C-3 alcohol and its acetate counterpart were synthesized for each compound. Evaluation of their anti-cancer effects revealed that all the acetate compounds showed strong cytotoxicity towards human melanoma (A375), human cervical adenocarcinoma (HeLa), and human metastatic melanoma (WM266) cells, a level comparable to or exceeding that of the original mycalin A lactone. D-ribonolactone-derived lactone acetates demonstrated superior selectivity in their cytotoxic action, affecting tested tumor cells significantly while exhibiting minimal toxicity towards healthy human dermal fibroblasts (HDFs). Experiments assessing wound healing indicated that two of these substances prevented the locomotion of WM266 cells.
