A fast, sensitive, and selective method for the simultaneous determination of one pair of synthetic colorants commonly found mixed in food products, Amaranth (AM) and Tartrazine (TZ), based on their adsorption and oxidation on a screen-printed electrode (SPE) is presented. The variation of peak current with pH, supporting electrolyte, adsorption time, and adsorption potential were optimized usi...

Food allergy is a public health concern in almost all over the world. Although allergic responses to food allergens vary markedly due to geographical differences, the lists of allergenic ingredients enshrined in different legislations are based on the original Codex recommendations with some regional variations. The patterns and prevalence of food allergy in Argentina -according to a survey car...

spontaneous abortion is the most common complication of pregnancy. several lines of evidence indicate that immunologic effector cells may play a role in the pathogenesis of idiopathic repetitive abortions. leukocytes form a substantial proportion of stromal cells in decidua and the endometrial granulated lymphocytes (egl) is the predominant decidual leukocyte population in the first trimester o...

An RT-PCR based microchip test system for the detection of SARS-CoV-2 offers pre-loaded and lyophilized reagents in microchip. However, 30- 48-microwell formats being miniaturized performing 1.2 μl reaction, seek visual attention during sample addition. Therefore, adding colorants as color indicator matrix microchips or to master mix can impart not only user-friendliness task liquid handling bu...

Mercury lamps are typically the major light sources in water treatments. However, use of mercury has raised some concerns with regard to Minamata Convention on Mercury. As such, Hg-free microwave discharged electrodeless (MDELs) that incorporate a rare gas and halogen (R/H-MDEL) have been investigated such mixture filler gases as Kr/Cl2, Xe/Cl2, Kr/Br2 (R/H). Of these, only Kr/Br2-MDEL lamp is ...
