- ArticleKo YG.Chemosphere. 2024 Sep;363:142909.A lot of research has been focused on increasing the specific surface area of adsorbents over a long period of time to remove heavy metal ions from wastewater using the adsorbent. However, porous adsorbents with high specific surface area have demonstrated drawbacks in water purification processes, such as high pressure drop and limitations in the adsorption capacity of heavy metal ions. In recent years, a mechanism-based convergence method involving adsorption/chemical precipitation has emerged as a promising strategy to surmount the constraints associated with porous adsorbents. The mechanism involves amine groups on chelating fibers dissociating OH- ions from water molecules, thereby raising the pH near the fibers. This elevated pH promotes the crystallization of heavy metal ions on the fiber surfaces. The removal of heavy metal ions proceeds through a sequence of adsorption and chemical precipitation processes. An adsorbent based on chelating fibers, integrating adsorption technology with chemical precipitation, demonstrates superior performance in removing significant quantities of heavy metal ions (ca. 1000-2000 mg/g for Cd2+, Cu2+ and Pb2+) when compared to developed porous adsorbents (ca. 50-760 mg/g for same ions). This review paper introduces advanced polymer fibers endowed with the capability to integrate hybrid technology, delves into the mechanism of hybrid technology, and examines its application in process technology for the effective removal of heavy metal ions. The versatility of these advanced fibers extends far beyond the removal of heavy metal ions in water treatment, making them poised to garner significant attention from researchers across diverse fields due to their broad range of potential applications. After further processes involving the removal of templates from chelating polymeric fibers used as supports and the reduction of precipitated heavy metal oxide crystals, the resulting heavy metal crystals can exhibit thin walls and well-interconnected porous structures, suitable for catalytic applications.
- ArticleHuang PH, Wu YY, Huang PH, Lin CM, Chen HL, Chen MH, Shih MK, Hou CY.Food Chem. 2025 Jan 17;472:142909.This study assessed the effects of Micro-bubble (MB; average size of 36.50 μm) on the physicochemical properties of live shrimp (Litopenaeus vannamei) and cooked ones. This study also examined the visual appearance, intestinal sludge's presence, microbial decontamination efficacy, and shrimp meat's textural properties. In addition, sensory evaluation was conducted to appraise the impact of MB on the gustatory and aromatic attributes of shrimp. This study showed that MB treatment was substantially better than traditional aeration (TA) treatment in terms of appearance, color, and intestinal sludge cleanliness. Specifically, all the above indicators exhibited optimal performance by the MB 30 group. Moreover, the MB treatment effectively decontamination microbes, reduced total volatile bases nitrogen (TVB-N; from 15.27 to 10.30 mg/100 g) and improved the textural indicators, while the best performed with the MB30 group. The sensory evaluation showed that the MB treatment groups exhibited enhanced aroma and taste profiles (7.45 to 8.00 points) of the shrimp compared to the TA (6.80 and 7.80 points) and control (7.15 and 7.25 points) groups, favored by the evaluation panels. Therefore, the findings of this study reveal that MB treatment provides a practical and invaluable theoretical framework to effectively address concerns about the quality and safety of live shrimp. Refraining from contamination during initial production would benefit stakeholders by reducing food and economic losses while ensuring longer shelf-life and safety of shrimp.
- ArticleOda Y, Ueda F, Utsuyama M, Kamei A, Kakinuma C, Abe K, Hirokawa K.PLoS One. 2015;10(12):e0142909.UNLABELLED: Plants belonging to the genus Salacia in the Hippocrateaceae family are known to inhibit sugar absorption. In a previous study, administration of Salacia reticulata extract in rats altered the intestinal microbiota and increased expression of immune-relevant genes in small intestinal epithelial cells. This study aimed to investigate the effect of S. reticulata extract in human subjects by examining the gene expression profiles of blood cells, immunological indices, and intestinal microbiota. The results revealed an improvement in T-cell proliferation activity and some other immunological indices. In addition, the intestinal microbiota changed, with an increase in Bifidobacterium and a decrease in Clostridium bacteria. The expression levels of many immune-relevant genes were altered in blood cells. We concluded that S. reticulata extract ingestion in humans improved immune functions and changed the intestinal microbiota.
TRIAL REGISTRATION: UMIN Clinical Trials Registry UMIN000011732. - ArticleCozzarelli IM, Kent DB, Briggs M, Engle MA, Benthem A, Skalak KJ, Mumford AC, Jaeschke J, Farag A, Lane JW, Akob DM.Sci Total Environ. 2021 Feb 10;755(Pt 1):142909.Releases of oil and gas (OG) wastewaters can have complex effects on stream-water quality and downstream organisms, due to sediment-water interactions and groundwater/surface water exchange. Previously, elevated concentrations of sodium (Na), chloride (Cl), barium (Ba), strontium (Sr), and lithium (Li), and trace hydrocarbons were determined to be key markers of OG wastewater releases when combined with Sr and radium (Ra) isotopic compositions. Here, we assessed the persistence of an OG wastewater spill in a creek in North Dakota using a combination of geochemical measurements and modeling, hydrologic analysis, and geophysical investigations. OG wastewater comprised 0.1 to 0.3% of the stream-water compositions at downstream sites in February and June 2015 but could not be quantified in 2016 and 2017. However, OG-wastewater markers persisted in sediments and pore water for 2.5 years after the spill and up to 7.2-km downstream from the spill site. Concentrations of OG wastewater constituents were highly variable depending on the hydrologic conditions. Electromagnetic measurements indicated substantially higher electrical conductivity under the bank adjacent to a seep 7.2 km downstream from the spill site. Geomorphic investigations revealed mobilization of sediment is an important contaminant transport process. Labile Ba, Ra, Sr, and ammonium (NH4) concentrations extracted from sediments indicated sediments are a long-term reservoir of these constituents, both in the creek and on the floodplain. Using the drivers of ecological effects identified at this intensively studied site we identified 41 watersheds across the North Dakota landscape that may be subject to similar episodic inputs from OG wastewater spills. Effects of contaminants released to the environment during OG waste management activities remain poorly understood; however, analyses of Ra and Sr isotopic compositions, as well as trace inorganic and organic compound concentrations at these sites in pore-water provide insights into potentials for animal and human exposures well outside source-remediation zones.
- Bookedited by Matt Delisi.Summary: "For over two centuries, psychopathy has stood as perhaps the most formidable risk factor for antisocial behavior, crime, and violence. The Routledge International Handbook of Psychopathy and Crime presents the state-of-the-art on the full landscape of research on antisocial behavior that employs psychopathy as a central correlate. It is the largest and most comprehensive work of its kind, and includes contributions from renowned scholars from around the world. Organized into five distinctive sections, this book covers the etiology of psychopathy; the measurement of psychopathy; the association between psychopathy and diverse forms of homicidal and sexual offending, including serial murder, sexual homicide, rape and child molestation; criminal careers and psychopathy; the role of psychopathy in criminal justice system supervision, including institutional misconduct, noncompliance, and recidivism. This book is an essential resource for students and researchers in criminology, psychology and criminal justice, and will be of interested to all those interested in criminal behavior, sexual and violent crime, forensic psychology and forensic mental health"-- Provided by publisher.
