| 1 | Antibacterial approaches in tissue engineering using metal ions and nanoparticles:From mechanisms to applications显示文摘Bacterial infection of implanted scaffolds may have fatal consequences and,in combination with the emergence of multidrug bacterial resistance,the development of advanced antibacterial biomaterials and constructs is of great interest.Since decades ago,metals and their ions had been used to minimize bacterial infection risk and,more recently,metal-based nanomaterials,with improved antimicrobial properties,have been advocated as a novel and tunable alternative.A comprehensive review is provided on how metal ions and ion nanoparticles have the potential to decrease or eliminate unwanted bacteria.Antibacterial mechanisms such as oxidative stress induction,ion release and disruption of biomolecules are currently well accepted.However,the exact antimicrobial mechanisms of the discussed metal compounds remain poorly understood.The combination of different metal ions and surface decorations of nanoparticles will lead to synergistic effects and improved microbial killing,and allow to mitigate potential side effects to the host.Starting with a general overview of antibacterial mechanisms,we subsequently focus on specific metal ions such as silver,zinc,copper,iron and gold,and outline their distinct modes of action.Finally,we discuss the use of these metal ions and nanoparticles in tissue engineering to prevent implant failure. | Maria Godoy-Gallardo Ulrich Eckhard Luis M.Delgado Yolanda J.D.de Roo Puente Mireia Hoyos-Nogués F.Javier Gil Roman A.Perez | 2021 | Bioactive Materials2021，6，12： | 14 |

| 19 | Adult hereditary fructose intolerance显示文摘Hereditary fructose intolerance(HFI) is an underrecognized,preventable life-threatening condition.It is an autosomal recessive disorder with subnormal activity of aldolase B in the liver,kidney and small bowel.Symptoms are present only after the ingestion of fructose,which leads to brisk hypoglycemia,and an individual with continued ingestion will exhibit vomiting,abdominal pain,failure to thrive,and renal and liver failure.A diagnosis of HFI was made in a 50-year-old woman on the basis of medical history,response to fructose intolerance test,demonstration of aldolase B activity reduction in duodenal biopsy,and molecular analysis of leukocyte DNA by PCR showed homozygosity for two doses of mutant gene.HFI may remain undiagnosed until adult life and may lead to disastrous complications following inadvertent fructose or sorbitol infusion.Several lethal episodes of HFI following sorbitol and fructose infusion have been reported.The diagnosis can only be suspected by taking a careful dietary history,and this can present serious complications. | Mohamed Ismail Yasawy Ulrich Richard Folsch Wolfgang Eckhard Schmidt Michael Schwend | 2009 | World Journal of Gastroenterology2009，15，19： | 0 |
| 20 | The BL Lac Object PKS 0537-441: A Lens or Being Lensed?显示文摘We present and discuss deep high resolution images taken with the ESO NTT as well as spectra taken with the ESO VLT in the field of the BL Lac object PKS 0537 441. We could neither detect the host galaxy nor a galaxy along the line of sight to the BL Lac as claimed from previous observations. We found 4 nearby companion galaxies which could be a splitted and magnified image of a distant background galaxy. Our VLT spectra, however, rule out this possibility. All 4 companions have similar redshifts as the BL Lac and may (at least in part) trigger the enormous activity in this source. PKS 0537 441 might be located in a galaxy cluster as rich as Abell 1. Alternatively, the BL Lac could also be located in the outskirts of a galaxy cluster or even be projected on a large scale structure as indicated by spectra of 30 galaxies in the field. Either lensing hypothesis (lens or being lensed) is considerably weakened by our observations. | Jochen Heidt Klaus Jger Kari Nilsson Ulrich Hopp Josef W.
