Fucoidan is a sulfated algal polyanionic polysaccharide that possesses many biological activities. In this paper, a fucoidan (SHF) polysaccharide was extracted from collected in the South China Sea. The SHF, with a molecular weight of 1166.48 kDa (44.06%, /), consisted of glucose (32.68%, /), galactose (24.81%, /), fucose (20.75%, /), xylose (6.98%, /), mannose (2.76%, /), other neutral monosaccharides, and three uronic acids, including glucuronic acid (5.39%, /), mannuronic acid (1.76%, /), and guronuronic acid (1.76%, /). The SHF exhibited excellent immunostimulatory activity. An immunostimulating assay showed that SHF could significantly increase NO secretion in macrophage RAW 264.7 cells via upregulation of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) levels based on both gene expression and protein abundance. These results suggest that SHF isolated from has great potential to act as a health-boosting ingredient in the pharmaceutical and functional-food fields.

Beeswax, an FDA-approved component, has been extensively applied in feed, pharmaceutical, and food industries. The occurrence of neonicotinoid pesticides in beehive systems and their residues in beeswax have caused safety risks. Therefore, establishing a detection method for neonicotinoid pesticide residues in beeswax is crucial for ensuring its quality.

Article Synopsis
  • Obesity is a significant risk factor for diseases, but it's still unclear how it contributes to disease development, prompting a study using Mendelian randomization to analyze the relationship between BMI, metabolic traits, and cholelithiasis.
  • BMI was found to positively affect the risk of developing cholelithiasis across multiple datasets, with 176 metabolites linked to BMI identified, including crucial fats and cholesterol types.
  • The study highlights key metabolites that mediate the BMI-cholelithiasis connection, emphasizing the need for effective BMI management to reduce metabolic dysfunction and gallstone risk, while calling for further research into the underlying metabolic pathways.

Background: Respiratory Syncytial Virus (RSV) infections are a cause of significant morbidity and mortality in children and the elderly. Despite the clinical burden of disease, very little is known about the inter- and intra-seasonal genomic variability of RSV. Furthermore, the recent approval of vaccines and monoclonal antibody therapies will likely lead to higher selective pressure on RSV.

Lead (Pb) pollution in soil affects growth of plants. Plants' endogenous hormones play an important role in resistance to Pb of plant. In order to explore the hormone-based mechanisms of Pb accumulationin in hyperaccumulator , a pot experiment was conducted to analyze the contents of endogenous hormones (auxin, gibberellin, abscisic acid, and cytokinin) and related genes expressions, and Pb contents of , as well as the transporter (cation exchangers (CAX), heavy metal ATPases (HMA), and ATP-binding cassette (ABC)) concentrations under foliar spraying of indoleacetic acid (IAA).
