Toxicity and health impact of nanoparticles. Basic biology and clinical perspective.
Authors: Olaru DG, Olaru A, Kassem GH, Popescu-Drigă MV, Pinoşanu LR, Dumitraşcu DI, Popescu EL, Hermann DM, Popa-Wagner A Abstract Stroke has limited restorative treatment options. In search of new therapeutic strategies for the ischemic brain, cell-based therapies offered new hope, which has been, in the meanwhile, converted into a more realistic approach recognizing difficulties related to unfavorable environments causing low survival rates of transplanted neuronal precursors. Stem cell therapies are based on the transplantation of neuronal precursor cells (NPCs), adult stem cells propagated in cell culture o...

Search strategies (filters) to identify systematic reviews in MEDLINE and Embase
CONCLUSIONS: Studies reporting the development, evaluation, or comparison of search filters to retrieve reports of systematic reviews in MEDLINE showed similar sensitivity and precision, with one filter showing higher levels of specificity. For Embase, filters showed variable sensitivity and precision, with limited information about how the filter was produced, which leaves us uncertain about their performance assessments. Newer filters had limitations in their methods or scope, including very focused subject topics for their gold standards, limiting their applicability across other topics. Our findings highlight that cons...

026: leaf extract mediated green synthesis of silver nanoparticles from widely available wedelia trilobata: synthesis, partial characterization and antimicrobial property analysis
Conclusion The leaf extract of Wedelia trilobata,in the volume, 1, 5, 10, 20 and 30 mL can reduce silver ions to silver particles that have max that are characteristic of silver nanoparticles. The inactiveness of silver nanoparticles against microorganism must be due to its bigger size.

A comparative study of neurotoxic potential of synthesized polysaccharide-coated and native ferritin-based magnetic nanoparticles.
Conclusions. Our study indicates that synthesized magnetite nanoparticles in contrast to ferritin have no effects on the functional state and glutamate transport of nerve terminals, and so ferritin cannot be used as a prototype, analogue, or model of polysaccharide-coated magnetic nanoparticle in toxicity risk assessment and manipulation of nerve terminals by external magnetic fields. Still, the ability of ferritin to change the functional state of nerve terminals in combination with its magnetic properties suggests its biotechnological potential.

Inhibition of intimal hyperplasia via local delivery of vascular endothelial growth factor cDNA nanoparticles in a rabbit model of restenosis induced by abdominal aorta balloon injury.
Authors: Xie H, Yang J, Han Y, Zhu X, Fang Q Abstract In-stent restenosis (ISR) is one of the major factors affecting long-term outcomes of percutaneous coronary interventions. Vascular endothelial growth factor (VEGF) has been hypothesized to have a positive role in preventing ISR, however, this remains controversial. The aim of the present study was to assess whether nanoparticles can be used to deliver VEGF to injured arteries and whether this is beneficial in preventing restenosis. New Zealand White rabbits were randomly divided into a control group, an empty nanoparticles group and a VEGF nanoparticles group (...

Wound healing effect of silver nanoparticles from Tridax procumbens leaf extracts on Pangasius hypophthalmus
In this study Silver nanoparticles were synthesized using Tridax procumbens leaf extract. Nanoparticles were characterized using UV–Vis absorption spectroscopy, and Scanning Electron Microscopy (SEM). The efficacy of the synthesized silver nanoparticles on wound healing was investigated in Pangasius hypohthalmus.Biosynthesis of silver nanoparticles from the leaf extract of Tridax procumbens was found to be cost effective and time conserving. We compared the effectiveness of the synthesized silver nanoparticles from Tridax procumbens on wound healing with silver nitrate and leaf extract.Collagen deposition and fibrosis fo...

Trends of Internet Search Volumes for Major Depressive Disorder Symptoms During the COVID-19 Pandemic in Korea: An Interrupted Time-Series Analysis
CONCLUSION: Our results reported the negative effect of COVID-19 preventive measures on public mental health in South Korea, especially for MDD symptoms. Moreover, the findings suggested the utility of Naver Trends as a feasible big data source to assess future mental health crises.PMID:35411728 | DOI:10.3346/jkms.2022.37.e108
