Summary: In this study, the performance of all-alumina multi-layer filters was evaluated by using three types of Al2O3 powders as raw materials, and an attempt was made to fabricate an ultrafiltration filter that can separate and remove proteins. When bovine serum albumin (BSA, molecular weight 66,000) was used as the protein, a very high rejection rate of 91.9% was achieved even under mild conditions with a differential pressure of 1 atm or less.

Summary: The dynamic and equilibrium surface tensions of Human Serum Albumin (HSA) and Bovine Serum Albumin (BSA) solutions were compared in this study, along with the dilational modulus of the adsorbed films. The results showed that HSA had a faster relaxation in dynamic surface tension compared to BSA, while the equilibrium surface tension remained constant for both HSA and BSA at different concentrations. The dilational modulus of the films exhibited similar concentration dependency for HSA and BSA.

Summary: This study investigated the removal mechanism of acrylamide using a combination of Lactobacillus strains and Bovine Serum Albumin (BSA). The addition of 0.5% BSA and 1010 CFU/mL Lactobacillus strains significantly improved the removal rate of acrylamide. The results indicated that increasing the surface hydrophobicity of the strains by adding BSA improved the removal rates of acrylamide. Fourier Transform Infrared (FTIR) Spectroscopy analysis showed the involvement of original functional groups in the removal process, X-ray Diffraction (XRD) analysis demonstrated the physical nature of the removal process, Scanning Electron Microscopy (SEM) images showed the maintenance of cell morphology, and Energy Dispersive X-ray Spectroscopy (EDS) analysis showed the importance of surface proteins and amino components in acrylamide removal. Zeta potential indicated the involvement of charge transfer in the removal process. Overall, the combination of Lactobacillus strains with BSA can be considered an effective, physical removal method for acrylamide.

Summary: The development of mitochondria-targeted bovine serum albumins (BSAs) conjugated with fluorescent, lipophilic, and cationic rhodamine 110 molecules enhances the proinflammatory phenotype of macrophages and inhibits their anti-inflammatory phenotype. Porous silicon nanocarriers further boost the immunomodulation of mitochondria-targeted BSAs, accompanied by the secretion of proinflammatory mediators. The mechanism involves the delivery of mitochondria-targeted BSA into macrophages to generate mitochondrial ROS and trigger proinflammatory signaling transduction pathways.

Summary: The continuous-welded rail (CWR) can generate longitudinal stress under temperature deviations from the neutral temperature (NT). Real-time monitoring of this longitudinal stress, or equivalently the NT, is a technical challenge. This paper explores the possibility of using nonlinear guided waves to detect the NT and investigates the effects of stress and temperature on the nonlinear parameter of different mode pairs. It is found that stress and temperature have significant influence on the nonlinear parameter, and decoupling their effects is crucial for NT detection. One mode pair shows a clear local minimum at NT, which can be used for NT detection without considering the coupling influence of temperature and stress.

Summary: The low cost and special structure of biomass materials make them suitable for many energy storage systems. In this study, NiCo2O4 nanowires growing on carbonized ginkgo biloba were developed and used as free-standing anodes for Li-ion batteries. The porous NiCo2O4 nanowires exhibited high capacity and could accommodate volume expansion during cycling. The NiCo2O4/ginkgo biloba anode showed good stability and recoverable rate performance at various current densities, outperforming NiCo2O4/nickel foam and NiCo2O4/carbon cloth. The cost-effective synthesis strategy provides opportunities for other metal oxide/ginkgo biloba-based composites.

Summary: The recent rise in air temperatures at high altitudes of the Tibetan Plateau has led to increased glacier melt and retreat, as well as enhanced monsoonal precipitation and increased runoff in lakes. These changes have resulted in rising water levels and alterations in the composition of local aquatic biota. Analysis of sediment cores from Nam Co, an endorheic lake, revealed an increase in chironomid richness since 1956, indicating higher water temperatures and intensified primary productivity. The dominance of littoral chironomid assemblages further suggests increasing lake water levels and flooded shorelines due to increased precipitation and glacial meltwater input.

Summary: As a potential probiotic for health promotion, Clostridium tyrobutyricum has limited industrial applications due to its weak tolerance to oxygen stress during fermentation. In this study, we enhanced its oxidative stress tolerance by deleting the perR gene using the CRISPR-Cas system, resulting in improved growth and butyric acid production in the presence of oxygen. Transcriptome analysis revealed upregulation of genes related to redox balance, and changes in metabolisms were observed. Furthermore, phylogenomic analysis suggested that PerR may be a target for engineering in diverse Clostridium species. These findings have implications for the development of robust C. tyrobutyricum strains for butyric acid production in the food industry.

Summary: In this study, a highly effective surfactant producer strain, Bacillus Cereus GX7, was isolated from the oil tank bottom sludge of Shengli Oil Field in China. The biosurfactant produced by GX7 was identified as surfactin, a lipopeptide surfactant, through TLC, FT-IR, and LC-MS/MS analysis. The fermentation process of GX7 was optimized using single-factor experiments, focusing on the composition of fermentation medium and fermentation conditions. Glucose and peptone were found to be the best carbon and nitrogen sources, and the optimum temperature, inoculum amount, pH, rotation speed, and fermentation time for the strain were determined to be 30°C, 1%, 7.5, 150 rpm, and 48 h, respectively. After optimization, the surface tension and emulsification index of the fermentation broth were 26.84 mN/m and 57.84%, respectively. Furthermore, the biosurfactant produced by GX7 demonstrated good stability over a wide range of temperature, pH, and salt concentration.

Summary: Effective management of biofluids is crucial for in vivo surgical interventions. Recent advances include self-sealing needles, drug-eluting stents, and shear-thinning hydrogels. However, complications associated with intestinal mucosal injury and secondary damage still persist. In this study, researchers developed an interpenetrating Janus wettability stent coating that enables unidirectional draining of excessive biofluid. They also demonstrated directional biofluid movement using a self-pumping dressing with potential applications in biofluid collection and disease diagnosis through metal ion detection. This integrated system presents an opportunity for designing wound dressings with effective biofluid management and metal ion detection capabilities.
