Royal Jelly Enhances the Social Status of Submissive Rats by Restoring Balance to the Disturbed Gut-Brain Communication.

Royal jelly (RJ) has long been considered a crucial dietary component in dictating caste differentiation in honeybees. As a nutritional additive, royal jelly imparts a broad range of benefits to mammals and humans; however, its precise impact on the social hierarchy of these advanced animals is not yet fully understood. This study aims to determine whether the benefits of royal jelly can be transferred to rats to alter their social ranks and uncover the underlying mechanisms.

Metabolic profile of procyanidin A2 by human intestinal microbiota and their antioxidant and hypolipidemic potential in HepG2 cells.

Purpose: Procyanidins have strong potential for antioxidation and decreasing hepatic fat accumulation thus preventing non-alcoholic fatty liver disease (NAFLD). Procyanidin A2 (PCA2), predominately found in cranberries, avocado, peanut red skins and litchi fruit pericarp, is poorly absorbed in the gastrointestinal tract. However, literatures about its metabolic profile by gut microbiota and effects on lipid metabolism are limited.

Anti-obesity effects of luteoloside on high fat diet induced obese mice: Modulation of white adipose tissue, gut microbiota, and PPAR signaling pathways.

The effect of luteoloside on the regulation of lipid metabolism imbalance in obese mice and its mechanism were investigated. After 12 weeks of luteoloside (25, 50 and 100 mg/kg), obesity-related indicators were analyzed, such as serum, liver and adipose tissue indexes as well as gut microbiota and liver tissue-related protein expression levels. The results suggested that luteoloside intervention could reduce body fat mass and fat storage, improve lipid levels, glucose tolerance, and alleviate inflammatory disorders, especially in medium-dose treated mice.

EDSSR: a secure and power-aware opportunistic routing scheme for WSNs.

Motivated by the pivotal role of routing in Wireless Sensor Networks (WSNs) and the prevalent security vulnerabilities arising from existing protocols, this research tackles the inherent challenges of securing WSNs. Many current WSN routing protocols prioritize computational efficiency but lack robust security measures, making them susceptible to exploitation by malicious actors. The prevalence of reactive protocols, chosen for their lower bandwidth consumption, exacerbates security concerns, as proactive alternatives require more resources for maintaining network routes.

Mgp High-Expressing MSCs Orchestrate the Osteoimmune Microenvironment of Collagen/Nanohydroxyapatite-Mediated Bone Regeneration.

Activating autologous stem cells after the implantation of biomaterials is an important process to initiate bone regeneration. Although several studies have demonstrated the mechanism of biomaterial-mediated bone regeneration, a comprehensive single-cell level transcriptomic map revealing the influence of biomaterials on regulating the temporal and spatial expression patterns of mesenchymal stem cells (MSCs) is still lacking. Herein, the osteoimmune microenvironment is depicted around the classical collagen/nanohydroxyapatite-based bone repair materials via combining analysis of single-cell RNA sequencing and spatial transcriptomics.

Low-intensity pulsed ultrasound reduces alveolar bone resorption during orthodontic treatment Lamin A/C-Yes-associated protein axis in stem cells.

Background: The bone remodeling during orthodontic treatment for malocclusion often requires a long duration of around two to three years, which also may lead to some complications such as alveolar bone resorption or tooth root resorption. Low-intensity pulsed ultrasound (LIPUS), a noninvasive physical therapy, has been shown to promote bone fracture healing. It is also reported that LIPUS could reduce the duration of orthodontic treatment; however, how LIPUS regulates the bone metabolism during the orthodontic treatment process is still unclear.

Characteristics variations of size-fractionated anammox granules and identification of the potential effects on these evolutions.

Anaerobic ammonium oxidation (anammox) granulation which contributed to system stabilization and performance improvement has great potential in the field of wastewater nitrogen removal. The researchers fractionated anammox granules into small-size (0.5-0.

M2 exosomes modified by hydrogen sulfide promoted bone regeneration by moesin mediated endocytosis.

Bone defects caused by trauma or tumor led to high medical costs and poor life quality for patients. The exosomes, micro vesicles of 30-150 nm in diameter, derived from macrophages manipulated bone regeneration. However, the role of hydrogen sulfide (HS) in the biogenesis and function of exosomes and its effects on bone regeneration remains elusive.

Ameliorative Effect of Ellagic Acid on Aging in Rats with the Potential Mechanism Relying on the Gut Microbiota and Urolithin A-Producing Ability.

Ellagic acid (EA) exhibits potential antiaging activity. Differences in individual ability to produce urolithins may result in large interindividual variability in the health effects of EA. Therefore, the effects and mechanism of EA on d-galactose-induced aging, considering urolithin A-producing ability, were investigated.

Apoptotic vesicles ameliorate lupus and arthritis via phosphatidylserine-mediated modulation of T cell receptor signaling.

Mesenchymal stem cells (MSCs) influence T cells in health, disease and therapy through messengers of intercellular communication including extracellular vesicles (EVs). Apoptosis is a mode of cell death that tends to promote immune tolerance, and a large number of apoptotic vesicles (apoVs) are generated from MSCs during apoptosis. In an effort to characterize these apoVs and explore their immunomodulatory potential, here we show that after replenishing them systemically, the apoV deficiency in mutant mice and pathological lymphoproliferation were rescued, leading to the amelioration of inflammation and lupus activity.

Annexin A3 accelerates osteoclast differentiation by promoting the level of RANK and TRAF6.

Annexin A3 (ANXA3), a member of Annexin family, is reported to mediate membrane transport and cancer development. However, the effect of ANXA3 on osteoclast formation and bone metabolism is still unclear. In this study, we found that knockdown of ANXA3 can significantly inhibit receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclast formation through NF-κB signaling.
