Dear Professor Barboni,
Letter to you as President elect of the International Phytolith Society have suggest me Professor Deborah Pearsall.
I am representing the research team consist of researchers of two universities: Wroclaw Medical University (Division of Normal Anatomy, Department of Human Morphology and Embryology) and University of Zielona Gora (Institute of Materials and Biomedical Engineering).
Currently we are reconstructing the living conditions and nutritional status in the early-modern city of Wroclaw (XVI-XVIII centuries, now Poland) on the basis of anthropological, genetic and chemical research. We are looking the partner for the current study evaluation of phytoliths from tartar from 18-20 teeth of children aged 4-10 years and 20 adult teeth for component comparison plant diets in the inhabitants of Wroclaw (bone remains come from cemetery at the church of St. Barbara in Wroclaw in the 16th-19th centuries). We have options dating layers from the cemetery where the remains come from human for our research C14 radioisotope method, the relative method assessment of artifacts and architectural assessment of the area of Wroclaw taking into account the city's moors, buildings within the parish and stratigraphy of the cemetery. It would be great to gauge the ingredients of a diet through phytolites, show their appearance in the photos of SEM. We are currently starting examination of microtraumas on the chewing surfaces of molars of individuals adults with the use of SEM, which arose as a chewing effect on several months before his death. This is also in conjunction with the information about vegetable ingredients will serve to assessment of eating habits.
Below is information about the recently published article from the Wrocław material:
