Orally administered dual-targeted astaxanthin nanoparticles as novel dietary supplements for alleviating hepatocyte oxidative stress.

The enhancement of bioavailability of food bioactive compounds as dietary supplements can be achieved through the development of targeted delivery systems. This study aimed to develop a novel dual-targeted delivery system for hepatocytes and mitochondria using phacoemulsification self-assembly. The delivery systems were engineered by modifying whey protein isolate (WPI) with galactose oligosaccharide (GOS) and triphenylphosphonium (TPP) to improve AXT transport to the liver and promote hepatic well-being.

Insights into the Influence of Signal Peptide on the Enzymatic Properties of Alginate Lyase AlyI1 with Removal Effect on Biofilm.

Most reports on signal peptides focus on their ability to affect the normal folding of proteins, thereby affecting their secreted expression, while few studies on its effects on enzymatic properties were published. Therefore, biochemical characterization and comparison of alginate lyase rALYI1/rALYI1-1 (rALYI1: without signal peptides; rALYI1-1:with signal peptides) were conducted in our study, and the results showed that the signal peptide affected the biochemical properties, especially in temperature and pH. rALYI1 (32.

MLK3 silence suppressed osteogenic differentiation and delayed bone formation via influencing the bone metabolism and disturbing MAPK signaling.

Background: Mixed lineage kinase 3 (MLK3) is a member of a serine/threonine MAP3K family, and it has been demonstrated to play critical roles in various biological activities and disease progression. Previous studies showed that impaired skeletal mineralization and spontaneous tooth fracture in the MLK3-deficient mice, suggesting MLK3 actively participated in the bone formation. However, the detailed function and underlying mechanisms remain obscure.

Microencapsulating Alginate-Based Polymers for Probiotics Delivery Systems and Their Application.

Probiotics exhibit many health benefits and a great potential for broad applications in pharmaceutical fields, such as prevention and treatment of gastrointestinal tract diseases (irritable bowel syndrome), prevention and therapy of allergies, certain anticancer effects, and immunomodulation. However, their applications are limited by the low viability and metabolic activity of the probiotics during processing, storage, and delivery in the digestive tract. To overcome the mentioned limitations, probiotic delivery systems have attracted much attention.

Baicalein mediates the anti-tumor activity in Osteosarcoma through lncRNA-NEF driven Wnt/β-catenin signaling regulatory axis.

Background: Osteosarcoma (OS) is a common type of malignant bone tumor in adolescents with high risk of metastasis. However, the clinical management still remains unsatisfactory. Traditional Chinese medicine (TCM) has been widely considered as an alternative treatment, and their extracts have proved to possess great potential for drug discovery.

Williamsia soli sp. nov., an actinobacterium isolated from soil at a thermal power plant in Yantai, China.

Strain C17, a novel strain belonging to the phylum Actinobacteria, was isolated from a thermal power plant in Yantai, Shandong Province, China. Cells of strain C17 were Gram stain positive, aerobic, pink, non-motile and round with neat edges, showing optimum growth at 28 °C. Phylogenetically, strain C17 was a member of the class Actinobacteria, order Mycobacteriales, family Gordoniaceae.

Kangiella shandongensis sp. nov., a novel species isolated from saltern in Yantai, China.

A Gram-stain-negative, wheat, rod-shaped, non-motile, non-spore forming, and facultatively anaerobic bacterium strain, designated as PI, was isolated from saline silt samples collected in saltern in Yantai, Shandong, China. Growth was observed within the ranges 4-45 °C (optimally at 33 °C), pH 6.0-9.
