Manadas Creek is an urban tributary of the Rio g.ande that flows past a decommissioned antimony smelter and processing.plant. This antimony plant is associated with heavy metal contamination in the creek and still poses a threat to the surrounding.aquatic environment. Corbicula fluminea was used to determine bioaccumulation from the water column and sediments in Manadas Creek. The metals arsenic (As), antimony (Sb) and thallium (Tl) were analyzed in the water, sediments, g.lls, mantle, foot, dig.stive (DI) tract, g.nads and shell of clams being.monitored at eig.t sites between March and Aug.st 2013. Sediment, water, and dissected Corbicula fluminea samples from different sites in the Creek were acid-dig.sted and analyzed by Inductively Coupled Plasma Optical Emission Spectroscopy. Hig. levels of antimony (25.88 ug.L;75.96 mg.kg. and arsenic (8.26 ug.L;6.41 mg.kg. in the water and sediments were observed at the site downstream from the smelter. There were no detectable concentrations of arsenic, antimony, or thallium in the shell of C. fluminea. Arsenic and antimony were detected in the tissues of C. fluminea but thallium was not detected. Based on the results, the org.notropism for arsenic is DI tract > g.lls > g.nads > foot > mantle > shell and the org.notropism for antimony is g.lls > DI tract > g.nads > mantle > foot > shell. This study shows that the Asiatic clam (Corbicula fluminea) is a useful bio-monitor to provide data on the status of metal pollution in Manadas Creek, Laredo, Texas.

Crude oil spillag. is a major challeng. in Nig.ria. It affects the environment, health, life, and livelihood of residents of the Nig.r Delta reg.on, where oil is explored, processed, and transported via a network of pipelines. Oil spillag. is primarily caused by vandalization/sabotag. and operational issues such as corrosion, equipment failure, operation, and maintenance errors. Thus, prompt response is required to mitig.te the impact of oil spills. In this study, we deployed low-cost Arduino systems, including.sensors (vibration and flow), modules (g.S and Wifi) and an IoT platform (Thing.peak) to detect spillag. caused by vandalism and operational inefficiencies proactively. The results demonstrate that low-cost sensors can detect chang.s in the flow volume between the inflow and outflow attributable to spillag., and vibration shocks caused by vandalism can be detected and linked to the cause of the spillag. and communicated in real time to inform response action. Moreover, we proposed a framework for field validation utilizing.KoboToolBox (a crowdsourcing.citizen science platform). The prototype system desig.ed and prog.ammed showed promising.results, as it could detect spillag. for vandalism and operational scenarios in real-time, quantify the volume of spillag., and identify the location and time of spillag. occurrence;indicators relevant for response planning.to minimize the impact of oil spillag.. A video demonstration of the prototype system developed is accessible via: https://***/wKa9MZvYf1w. .

Introduction:Alzheimer 's disease(AD) is a common neurodeg.nerative disorder and the primary cause of dementia. Considerable evidence supports the “amyloid hypothesis,” stating.that the pathog.nesis of AD is primarily caused by the deposition of amyloid-β(Aβ), which drives tau phosphorylation, neuroinflammation, and neurodeg.neration in the brain. The amyloid hypothesis is streng.hened by the sig.ificant and moderate benefit of lecanemab, a humanized antibody throug. an anti-amyloid mechanism,showing.slowed clinical decline(van Dyck et al.,2023). The recent positive results of anti-amyloid trials have broug.t back focus on the amyloid hypothesis throug. biochemical, g.netic, and pharmacolog.cal approaches(Zhang. 2023).
