Mechanical pressure at 10 bar of fresh seaweed fronds casu quo biomass in the laboratory delivered seaweed moisture which was analyzed by Inductively Coupled Plasma Spectroscopy (ICP)-techniques for heavy-metals = [HM], (Al, As, Cd, Co, Cr, Cu, Fe, Mo, Ni, Pb & Zn). Three important observations were made: 1) The [HM] in the seaweed moisture is higher than in the surrounding seawater which directs to mechanism(s) of bio-accumulation;2) The accumulation factor [AF] is varying per metallic-cation with an overall trend for our four seaweeds and sampling locations for [HM] are: As & Co & Cu: 5000 - 10,000 μg/l;Ni & Zn: 3000 - 5000 μg/l;Cd: 2000 - 3000 μg/l;Cr: 1000 - 2000 μg/l;Al: 200 - 1000 μg/l;Mo & Pb & Fe: 0 - 200 μg/l range. 3) Seaweed moisture detected that [HM]: Pb & Zn & Fe—which all three could not be detected in the seawater—supports the view that seaweeds have a preference in their bio-accumulation mechanism for these three HM. Major conclusion is in general that “overall” for the macro-elements Ca, Fe, K, Mg, Mn, Na, P & S in the moisture of the four seaweed species the concentration is lower in the seaweed species, or equals the concentration, in comparison to the surrounding sea water. For the HM (Al, As, Cd, Co, Cr, Cu, Mo, Ni, Pb & Zn) the opposite is the case species and is the concentration “overall” higher in the seaweed species in comparison to the surrounding sea water. Further topics addressed include strategies of irrigation of the Sahara desert with the moisture out of seaweeds under conditions of low anthropogenic influences.展开更多
伪狂犬病病毒(PRV)是一种对猪和其他哺乳动物造成严重危害的病原体,它能够引发宿主的系统性炎症反应和炎症损伤。尽管已知PRV感染与炎性小体的激活和焦亡有关,但PRV促进炎性小体激活的具体分子机制尚不清楚。2024年9月24日,西北农林科...伪狂犬病病毒(PRV)是一种对猪和其他哺乳动物造成严重危害的病原体,它能够引发宿主的系统性炎症反应和炎症损伤。尽管已知PRV感染与炎性小体的激活和焦亡有关,但PRV促进炎性小体激活的具体分子机制尚不清楚。2024年9月24日,西北农林科技大学研究团队在PLoS Pathogens在线发表了题为“Pseudorabies virus UL4 protein promotes the ASC-dependent inflammasome activation and pyroptosis to exacerbate inflammation”的最新研究成果,鉴定出PRV非结构蛋白UL4的关键功能,揭示其如何增强ASC依赖性的炎性小体激活,促进焦亡,并加剧炎症反应。这一研究成果对于开发新的疫苗和治疗策略具有重要意义。展开更多
