Toxicity of nano- and micro-sized ZnO particles in human lung epithelial cells
Exposure to both sizes of ZnO particles leads to dose- and time-dependent cytotoxicity reflected in oxidative stress, lipid peroxidation, cell membrane damage, and oxidative DNA damage, as well as a much steeper dose–response pattern unseen in other metal oxides.
Toxicity of Cerium Oxide Nanoparticles in Human Lung Cancer Cells
The cytotoxicity and oxidative stress caused by 20-nm cerium oxide (CeO2) nanoparticles in cultured human lung cancer cells was investigated and it was concluded that free radicals generated by exposure to 3.5 to 23.3 μg/ml CeO2 nanoparticles produce significant oxidative stress in the cells.
Comprehensive profiling of isoflavones, phytosterols, tocopherols, minerals, crude protein, lipid, and sugar during soybean (Glycine max) germination.
Isoflavone, phytosterol, tocopherol, mineral, protein, lipid, and sugar contents of soybeans were analyzed during 7-day germination with or without exposure to light to study the effect of light on the levels of the micro- and macronutrients in soybeans.
Assessment of metal contaminations leaching out from recycling plastic bottles upon treatments
The results revealed that heating and microwaving enhance antimony leaching significantly in PET plastic bottles, and manufacturers should consider the contaminations during manufacturing process and washing bottles before first use was strongly recommended to remove those contaminants.
Quantitative determination of sarcosine and related compounds in urinary samples by liquid chromatography with tandem mass spectrometry.
A novel method was developed to separate and quantify six urinary metabolites including creatinine in urine samples by using liquid chromatography/tandem mass spectrometry and it can be used for quantifying these six metabolites in urine sample for potential early cancer screening.
Cytotoxicity and cell membrane depolarization induced by aluminum oxide nanoparticles in human lung epithelial cells A549
The cytotoxicity of 13 and 22 nm aluminum oxide (Al2O3) nanoparticles was investigated in cultured human bronchoalveolar carcinoma-derived cells (A549) and compared with 20 nm CeO2 and 40 nm TiO2
A novel enzymatic technique for determination of sarcosine in urine samples
A new technique, utilizing oxidative, enzymatic production of formaldehyde from the metabolite to produce a pH-induced change observed by fluorescein in acetone is developed, suggesting that this is a viable, cost-effective technique for determination of sarcosine in urine samples without interferences such as alanine.
