Regional long-term analysis of dietary isotopes in Neolithic southeastern Italy: new patterns and research directions.

Isotopic analyses of prehistoric diet have only recently reached the threshold of going beyond site-focused reports to provide regional syntheses showing larger trends. In this work we present the first regional analysis for Neolithic southeastern Italy as a whole, including both substantial original data and a review of the available published data. The results show that dietary isotopes can shed new light on a number of traditional and important questions about Neolithic foodways. First, we observe regional variations in the distribution of stable isotope values across the area, suggesting variability in the Neolithic diet. Secondly, we show that, although the plant food calorific intake was primary for these communities, animal products were also important, representing on average 40% of the total calories. Third, we note that marine fish was only minorly consumed, but that this could be an underestimation, and we observe some variability in the regions considered, suggesting differences in local human-environment interactions. People in different regions of southeastern Italy may have consumed different versions of a common Neolithic diet. Regional synthesis also allows us to take stock of gaps and new directions in the field, suggesting an agenda for Neolithic isotopic research for the 2020s.

Determination of styrene content in Gorgonzola PDO cheese by headspace solid phase micro-extraction (HS-SPME) and gas-chromatography mass-spectrometry (GC-MS).

Control of the composition of products that are intended for use as packaging material is essential, particularly when these products come into direct contact with food. It is well known that plastics are not inert and that their residual monomers, starting substances, and additives are able to migrate into the food they contact. Among plastics, styrene is a common compound found in many plastic containers that can also be produced by the oxidation of Penicillium roqueforti used in gorgonzola Protected Denomination of Origin cheese manufacturing. Therefore, solid-phase microextraction combined with gas chromatography/mass spectrometry was applied in the present work to determine the styrene content in packaged and unpackaged gorgonzola cheese samples to understand styrene migration phenomena from plastic containers.

Verminoses / Intestinal parasitosis (verminosis)

Escolhendo o tema das verminoses, o Grupo Interdisciplinar e Multiprofissional n§9 (GIM-9) fez um levantamento da frequência de positividade de verminose entre a populaçäo da área de abrangência da Unidade Básica de Saúde do Jardim Leonor, em Londrina, e, em seguida, procurou proporcionar maior informaçäo àquela populaçäo sobre a importância de cuidados básicos, higiene pessoal e saneamento básico. Como objetivos secundários, decorrentes do processo de aprendizagem, destacamos a integraçäo e desenvolvimento em equipe multidisciplinar, o amadurecimento ético e humanístico e o despertar do espírito crítico logo no início da nossa formaçäo profissional
