Diagnostic Characteristics

Toxins - molecular weight compounds produced by microorganisms, animals, plants and possessing antigene properties. Recently due to the perceived threat of terrorist actions identification of a number of bacterial toxins is especially important. A new approach in the identification of toxins associated with the development of mass spectrometry and can be successfully used for analysis of most environmental toxins. The method of MALDI-MS allows the detection of toxins such as Shiga-toxin Escherichia coli, delta-toxin of Staphylococcus aureus, Bacillus cereus particular, botulinum neurotoxin, cholera toxin. Analytical and diagnostic characteristics of the method, the simplicity and speed studies indicate the long term implementation of a method in the practice of laboratory diagnostics in determining toxinproducing of the studied microorganisms.

Summary paragraphMicroplastics are particles smaller than five millimetres obtained from the degradation of plastic objects abandoned in the environment. Microplastics can move from the environment to living organisms and, in fact, they have been found in fishes and mammals.Six human placentas, prospectively collected from consenting women with uneventful pregnancies, were analyzed by Raman Microspectroscopy to evaluate the presence of microparticles. Detected microparticles were characterized in terms of morphology and chemical composition.12 microparticles, ranging from 5 to 10 μm in size, were found in 4 out of 6 placentas: 5 in the foetal side, 4 in the maternal side and 3 in the chorioamniotic membranes. All the analyzed microparticles were pigmented: three of them were identified as stained polypropylene, while for the other nine it was possible to identify only the pigments, which are all used for man-made coatings, paints and dyes.Here we show, for the first time, the presence of microparticles and microplastics in human placenta. This sheds new light on the impact of plastic on human health. Microparticles and microplastics in the placenta, together with the endocrine disruptors transported by them, could have long-term effects on human health.
