Carcinogenic, ethanol, acetaldehyde and noncarcinogenic higher alcohols, esters, and methanol compounds found in traditional alcoholic beverages. A risk assessment approach.

Greek fermentation and distillation industries produce traditional spirit beverages, such as tsipouro and tsikoudia, consumed both in bottles and bulk quantities by the general population or tourists. The same spirits are also produced by individuals at home since previous centuries, as a part of the local culture but mainly due to the Greek agricultural sector unique characteristics (small cultivation areas with great number of farmers). In this study, the concentrations of carcinogenic compounds: ethanol and acetaldehyde; and noncarcinogenic: higher alcohols (1-propanol, isobutanol, and isoamyl alcohol), esters (ethyl acetate), and methanol were measured to estimate the potential cancer risk and daily intake of these compounds.

C-reactive protein: what to expect after bony hip surgery for nonambulatory children and adolescents with cerebral palsy.

Bony hip reconstruction surgery in children with severe cerebral palsy is associated with high complication rates, usually postoperative chest and urinary tract infections. C-reactive protein (CRP) level is commonly used as an indication of infection; an understanding of its normal postoperative trends is crucial to allow early identification of abnormal levels and possible infection. Our aim was to describe the trends in CRP following bony hip surgery in children who had an uneventful postoperative course, on the basis that the children for whom CRP does not follow this course are likely to have a bacterial infection.

Morphological and chemical composition of particulate matter in buses exhaust.

This research article investigates the particulate matter originated from the exhaust emissions of 20 bus models, within the territory of Vladivostok, Russian Federation. The majority of evaluated buses (17 out of 20) had emissions of large particles with sizes greater than 400 μm, which account for more than 80% of all measured particles. The analysis of the elemental composition showed that the exhaust emissions contained Al, Cd, Cu, Fe, Mg, Ni, Pb, and Zn, with the concentration of Zn prevailing in all samples by two to three orders of magnitude higher than the concentrations of the other elements.
