Project description:The Kashmiri population is an ethno-linguistic group that resides in the Kashmir Valley in northern India. A longstanding hypothesis is that this population derives ancestry from Jewish and/or Greek sources. There is historical and archaeological evidence of ancient Greek presence in India and Kashmir. Further, some historical accounts suggest ancient Hebrew ancestry as well. To date, it has not been determined whether signatures of Greek or Jewish admixture can be detected in the Kashmiri population. Using genome-wide genotyping and admixture detection methods, we determined there are no significant or substantial signs of Greek or Jewish admixture in modern-day Kashmiris. The ancestry of Kashmiri Tibetans was also determined, which showed signs of admixture with populations from northern India and west Eurasia. These results contribute to our understanding of the existing population structure in northern India and its surrounding geographical areas.
Project description:The objective of this study was to identify potentially remaining CeD-active peptides in the hydrolyzed and fermented food products BME, barley malt vinegar (BMV), and soy sauce with high resolution untargeted nanoLC-MS/MS method. Secondly, we aimed to quantitate the absolute concentrations of selected CeD-active peptides in the samples by targeted nanoLC-MS/MS with SIDA. The knowledge of the remaining concentrations of CeD-active peptides in fermented and hydrolyzed products enables a more reliable scientific basis for risk assessment of such food products.
Project description:The research on alternative and sustainable feed ingredients is a challenge to reduce the feed-food competition between humans and monogastrics, in particular pigs. Former food products (FFPs) drop out from the industrial production of food such as pasta, bread, snacks and chips. They have a high nutritional and energetic value and represent an alternative and sustainable feed ingredient. The aim of this study was to apply label-free quantitative peptidomics to assess the impact of the inclusion of FFPs on serum peptidome.
