Summary: The study demonstrates the potential of underexploited tropical green seaweed resources, such as Caulerpa racemosa and Ulva lactuca, as sources of antioxidants for nutraceutical and cosmeceutical products. Subcritical water extraction shows higher extraction yield and higher content of bioactive compounds compared to conventional hot water extraction, indicating its potential for producing high-quality seaweed hydrolysates.

Summary: This study investigated the cardioprotective effects of thermally treated sodium alginate (TTSA) in treating doxorubicin-induced cardiotoxicity. The results showed that TTSA improved cardiac dysfunction and alleviated doxorubicin-induced myocardial apoptosis. Furthermore, TTSA exhibited antioxidant properties and rebalanced the redox state of cardiomyocytes.

Summary: The study demonstrated that PCR has antidiabetic and nephroprotective effects against diabetic nephropathy by alleviating hyperglycemia, dyslipidemia, renal oxidative stress, inflammation, and fibrosis. It suggests that PCR could be a potential food supplement for alleviating renal dysfunction caused by diabetes.

Summary: This study focused on the impact of 3 key variables (macroalgae mass, water salinity, and Nd(III) initial concentration) on the performance of two living macroalgae in the removal and bioaccumulation of Nd(III), finding optimal operating conditions through Response Surface Methodology (RSM). The results showed that under lower water salinity and higher macroalgae mass conditions, the removal efficiency of Nd(III) was the best.

Summary: This study investigated the impact of seaweed supplementation on the distribution and metabolites of arsenic in broiler breasts, revealing significant variations between Ulva lactuca and Sargassum hemiphyllum var. chinense in terms of arsenic species and metabolites. The use of SHC-containing feeds in poultry production should be approached cautiously due to the potential accumulation of inorganic arsenic species in chicken breasts.

Summary: The pollution of microplastics in the ocean is a serious concern. This study investigates the interaction between two types of seaweed and two typical classes of microplastics, and explores methods of removing microplastics from seaweed. The results demonstrate different effects of the two types of microplastics on seaweed.

Summary: The study compared the productivity and characteristics of lipids and biodiesels between marine ulva lactuca seaweed and freshwater azolla filiculoides macroalgae. The results showed that 7.6 +/- 0.10% and 12.52 +/- 0.23% of lipids were extracted from ulva lactuca and azolla filiculoides, respectively. The study also analyzed the kinetics and thermodynamics of oil extraction and conducted base-catalyzed transesterification to synthesize biodiesel fuel.

Summary: This study evaluated the feasibility of using Sargassum sp., Spirulina sp., and Gracilaria sp. as poultry feed and found that they can partially substitute imported protein sources. It also suggested promising opportunities to harvest algae from the marine area, but establishing outdoor algal ponds in the Middle East is not environmentally viable.

Summary: This study evaluated the potential of an enzyme called ulvan lyase to degrade the cell walls of green macroalgae and release nutritive compounds. The results showed that ulvan lyase was the most efficient enzyme in disrupting the cell walls and promoting the release of reducing sugars and monosaccharides. However, there was no significant release of fatty acids, proteins, or pigments. These findings suggest that ulvan lyase has the potential to enhance the bioaccessibility of bioactive products from green macroalgae for use in the feed industry.

Summary: This study compared the biological characteristics of Sargassum fusiforme and its epiphytic algae Ulva lactuca and found that Ulva lactuca generally had higher photosynthetic electron activity and nitrogen uptake and utilization rates compared to S. fusiforme, which may lead to stress on S. fusiforme.

Summary: A study was conducted to investigate the bioaccumulation of citrate-coated titanium dioxide nanoparticles in red (Palmaria palmata) and green (Ulva sp.) seaweed. The results showed that Ulva sp. had higher titanium concentrations than Palmaria palmata under the same exposure conditions. The titanium concentration in Ulva sp. reached its maximum after 28 days of exposure to 1.0 mgL(-1) of 5 nm TiO(2)NPs. The sizes and concentrations of TiO(2)NPs determined by SP-ICP-MS were similar for both seaweeds, suggesting that the titanium is mainly accumulated in Ulva sp. as ionic titanium or nanoparticles smaller than the limit of detection in size.
