Article Abstract
Objective: To investigate the effects of sodium alginate(SA) on serum total cholesterol(TC) levels in individuals with hypercholesterolemia.
Methods: A randomized double-blind controlled trial was conducted on hypercholesterolemic patients(TC≥5.2 mmol/L, n=84), who were divided into a control group and an SA intervention group. General demographic and physical examination data were collected. Serum levels of TC, triglycerides(TG), low-density lipoprotein cholesterol(LDL-C) and high-density lipoprotein cholesterol(HDL-C) were measured before and after the intervention. Changes in TC, TG, LDL-C, and HDL-C were calculated as baseline values minus post-intervention values(28 days), followed by comparative analyses.
Results: SA showed no significant effects on body weight or body mass index(BMI). However, SA reduced lipid levels: the ΔTC, ΔTG, and ΔLDL-C in the SA intervention group were higher compared to the control group(P<0.05). The lipid-lowering effects increased with higher baseline TC levels(r=0.476, P<0.001). The participants with TC ≥6.2 mmol/L demonstrated significantly higher ΔTC and ΔLDL-C compared to the control group(P<0.01).
Conclusion: Sodium alginate significantly reduces serum TC and LDL-C levels in hypercholesterolemic patients, with particularly pronounced effects in patients with TC≥6.2 mmol/L.

At present, flexible sensors are a hot spot in research and experimental development, but the research on flexible sensors that can be used for human motion monitoring still needs to be deepened. In this work, the green material cellulose acetate (CA) was used as the matrix material, the film was made by electrospinning, crushed by a cell grinder and sodium alginate (SA) was added to promote the uniform dispersion of nanofibers in water, and then methyltrimethoxysilane (MTMS) and MXene nanosheet dispersion were added to make it hydrophobic and good conductivity, and the aerogel precursor solution was prepared, and then the CA/SA/MTMS/MXene aerogel with directional holes was prepared by directional freeze-drying. As a flexible sensor material, it can be used for human wear, monitoring the electrical signals generated by the movement of human joints and other parts, and can still maintain a current of about 0.

Bioprotective LAB3 cells that produce bacteriocin-like substances were entrapped in 4% (w/w) sodium alginate matrices, either with or without 10% (w/w) sodium caseinate. The effects of bead formulation-alginate alone or combined with caseinate, with or without the addition of 20% (w/w) MRS broth or M17 broth-on the culturability of LAB3 cells within the beads and their anti activity were assessed over 12 days of storage at 30 °C in closed bottles. Calcium-alginate-caseinate beads supplemented with MRS broth proved most effective in preserving both culturability and anti- activity.

This study focuses on the issues of poor fluidity, low penetration into residual coal, and suboptimal inhibition of coal spontaneous combustion associated with traditional coal mine gel fire retardants. The permeability and flow characteristics of a sodium alginate-based composite thermosensitive hydrogel, as well as its fire prevention and extinguishment performance, were investigated. The findings suggest that the thermosensitive hydrogel behaves as a pseudoplastic fluid at 40 °C and a yield-pseudoplastic fluid at 65 °C, exhibiting shear-thinning behavior with increasing shear rate.

Introduction: Burn wounds are painful injuries that demand immediate and effective management. Conventional wound care solutions often have limitations, such as discomfort during application or removal and potential damage to healing tissue. Therefore, developing novel wound dressings that support biological processes and promote wound healing is highly beneficial.
