Summary: Sterile filtration is commonly used in processing recombinant proteins to remove microorganisms, but applying this technology to larger biotherapeutics like Live-Attenuated Vaccines (LAV) poses challenges. This study evaluated the fouling behavior of eight different sterile filters using fluorescently-labeled latex spheres as model particles, finding a correlation between particle diameter, pore size, and transmission rates. The results provide insights into the selection of appropriate sterile filters for processing vaccines and viruses larger than 100 nm.

Summary: This paper explores the use of extinction spectroscopy to characterize colloidal suspensions of gold nanoparticles, demonstrating the ability to deduce size distribution from extinction spectra using Mie theory. The method, based on non-negative least square algorithm, is sensitive to changes in plasmon band and does not require prior information on nanoparticle size distribution. It is shown that this characterization tool is compatible with in situ measurement and can track changes in nanoparticles' radii during laser exposure.

Summary: The study aimed to identify mercury-associated protein spots in the liver tissue of rats exposed to low concentrations of mercury and examine their physiological and functional aspects. Proteomic analysis of the liver tissue of Wistar rats exposed to mercury chloride was conducted, revealing 10 mercury-associated protein spots. LC-MS/MS analysis identified 11 metal binding proteins in these spots, with some showing higher mercury concentrations and downregulation, and others being expressed only in the Hg-60 group. Bioinformatics analysis suggested that these proteins, such as GSTM2, Acaa2, and Bhmt, may serve as potential biomarkers for mercury exposure.

Summary: A study found a positive correlation between selenium and mercury in freshwater fish. Selenium mitigates the toxicity of mercury but can divert from biosynthetic pathways. The study also observed a surplus of selenium in fish and found that it decreased with fish weight. This suggests that selenium accumulation is subject to homeostatic control and is related to the burden of mercury and selenium requirement.

Summary: Intrusion curves under mercury intrusion porosimetry (MIP) often underestimate pore sizes below the actual pore-size distribution (APSD), resulting in difficulties in interpreting the dominant pore structure in various concrete performances. This study proposes a method to accurately estimate the APSD from a MIP intrusion curve by considering the ink-bottle effect. By incorporating a model for calculating the volume of the ink-bottle pores into the inverse analysis system, the APSD can be obtained through a three-dimensional intrusion simulation. The APSD estimation results of the proposed method are in good agreement with those of existing methods.

Summary: This study evaluated the separation ability of biased cyclical electrical field-flow fractionation (BCyElFFF) for polyvinyl pyrrolidone-coated and poly(ethylene glycol)-coated silver nanoparticles (AgNPs) with different electrophoretic mobilities, and elucidated the mechanism behind the formation of NOM corona on these AgNP surfaces. Furthermore, it was observed that the survival rates of E. coli exposed to AgNPs with or without NOM corona collected during repeated BCyElFFF runs increased with increasing NOM concentration, indicating the negative effect of NOM coronas on the bioavailability of AgNPs. These findings highlight the powerful capability of BCyElFFF in studying the fate and transformation of nanoparticles in aqueous environments.

Summary: This study constructed an Escherichia coli strain overexpressing merB gene (DH5 alpha J23106) and evaluated its effectiveness in degrading methylmercury (MeHg) in culture medium and sediment. Results showed that DH5 alpha J23106 could efficiently degrade MeHg in the culture medium under anoxic and oxic conditions. It could also degrade newly produced Me199Hg in actual sediment but with decreased efficiency for intrinsic MeHg. DH5 alpha J23106 showed potential in remediating bioavailable MeHg in contaminated sediments.

Summary: Methylmercury (MeHg) is a global environmental concern derived from industrial processes and microbial methylation. This study presents a new method using ligand-enhanced Fenton-like reaction to rapidly degrade MeHg at neutral pH. Results showed that three common chelating ligands (NTA, citrate, and EDTA) promoted MeHg degradation, with EDTA exhibiting the highest efficiency. Scavenger addition revealed the involvement of hydroxyl radical, superoxide radical, and ferryl in MeHg degradation, with their contributions dependent on the ligand type. Furthermore, environmental factors such as pH, organic complexation, and inorganic ions were also investigated for their impact on MeHg degradation.

Summary: This study verifies the importance of mercurous species (Hg(I)) in natural water contaminated by liquid elemental mercury droplet (Hg(0)l) and in simulating the dark oxidation process of Hg(0)l. The formation and transformation of Hg(I) control the overall oxidation of Hg(0)l and are influenced by environmental factors. The conversion of Hg(0) to Hg(I) is the rate-limiting step in the oxidation process, and ligands like OH-, Cl-, and natural organic matter can enhance the formation of Hg(I).
