Use of long acting injectable aripiprazole before and through pregnancy in bipolar disorder: a case report
2019
Abstract Background Long-acting injectable (LAI) antipsychotics for psychotic disorders provide advantages in treatment compliance, but data on their use in pregnancy are very limited. We present a clinical case of aripiprazole LAI use in pregnancy. Case presentation A 43-year-old woman diagnosed with bipolar disorder, with several relapses due to treatment interruption while trying to conceive. Finally, aripiprazole LAI treatment was planned by mutual agreement between doctor and the patient, who took aripiprazole LAI before and during pregnancy. She gave birth at 40 weeks to a 3500 g baby girl with no congenital malformations, who was healthy at 5 months after delivery. Conclusion As far …

Phenolic Extract from Sonchus oleraceus L. Protects Diabetes-related Liver Injury in Rats through TLR4/NF-κB Signaling Pathway
2019
Sonchus oleraceus Linn. is of great interest in scientific platform because it exhibits significant biological activities. This study investigated the liver protective effects and mechanism of phenolic extract from S. oleraceus (SOL) on Streptozotocin (STZ)-induced diabetic rats. SOL significantly increased both superoxide dismutase activity and glutathione level, while causing a reduction of malondialdehyde level in the liver. Moreover, SOL ameliorates STZ-induced liver function and pathological damages. Diabetic rats fed with S. oleraceus daily for 6 weeks showed significantly decreased levels of tumor necrosis factor alpha and interleukin-1β in the liver. Sonchus oleraceus decreased the …
Uptake and cytotoxicity of citrate-coated gold nanospheres : comparative studies on human endothelial and epithelial cells
2012
Abstract Background The use of gold nanoparticles (AuNPs) for diagnostic applications and for drug and gene-delivery is currently under intensive investigation. For such applications, biocompatibility and the absence of cytotoxicity of AuNPs is essential. Although generally considered as highly biocompatible, previous in vitro studies have shown that cytotoxicity of AuNPs in certain human epithelial cells was observed. In particular, the degree of purification of AuNPs (presence of sodium citrate residues on the particles) was shown to affect the proliferation and induce cytotoxicity in these cells. To expand these studies, we have examined if the effects are related to nanoparticle size (1…
Inflammatory and cytotoxic responses of an alveolar-capillary coculture model to silica nanoparticles: Comparison with conventional monocultures
2011
Abstract Background To date silica nanoparticles (SNPs) play an important role in modern technology and nanomedicine. SNPs are present in various materials (tyres, electrical and thermal insulation material, photovoltaic facilities). They are also used in products that are directly exposed to humans such as cosmetics or toothpaste. For that reason it is of great concern to evaluate the possible hazards of these engineered particles for human health. Attention should primarily be focussed on SNP effects on biological barriers. Accidentally released SNP could, for example, encounter the alveolar-capillary barrier by inhalation. In this study we examined the inflammatory and cytotoxic response…
Gold nanoparticles induce cytotoxicity in the alveolar type-II cell lines A549 and NCIH441.
2009
Abstract Background During the last years engineered nanoparticles (NPs) have been extensively used in different technologies and consequently many questions have arisen about the risk and the impact on human health following exposure to nanoparticles. Nevertheless, at present knowledge about the cytotoxicity induced by NPs is still largely incomplete. In this context, we have investigated the cytotoxicity induced by gold nanoparticles (AuNPs), which differed in size and purification grade (presence or absence of sodium citrate residues on the particle surface) in vitro, in the human alveolar type-II (ATII)-like cell lines A549 and NCIH441. Results We found that the presence of sodium citra…
Some Plant Defense Stimulators can induce IL-1β production in human immune cells in vitro
2020
8 pages; International audience; Among Plant Protection Products (PPP), a new emerging category of pesticides act by stimulating plant defense in order to improve plant resistance against microbial pathogens. Given that these compounds, the so-called Plant Defense Stimulators (PDS) act on innate immunity, we tested, using an in vitro approach on human mononuclear leucocytes (PBMC), the potential toxicity (XTT assay) and inflammatory effects (production of IL-1β) of 4 PPP belonging to different chemical families. We found that two products (LBG-01F34® and Regalis®) did not induce any cytotoxicity or IL-1 β production. The product BION-50 WG®, that contains Acibenzolar-S-methyl (ASM) and sili…
