Project description:In order to understanding the mechanisms of action of niclosamide, the active ingredient in the molluscicides, we used a Biomphalaria glabrata oligonucleotide microarray to investigate the effect of three sublethal exposures to niclosamide on the transcriptional responses of the snail B. glabrata relative to untreated snails. In addition to inducing biotransformation activity and inducing stress responses, niclosamide exposures also resulted in altered function of vesicle trafficking and may affect the snail’s oxygen binding capacity. In order to reveal how sublethal exposures of niclosamide to the snail B. glabrata affects the snail’s gene expression. The three sublethal doses of niclosamide tested are 0.15 mg/L (dose 1), 0.10 mg/L (dose 2), and 0.05 mg/L (dose 3). The control snails did not exposed to the niclosamid (0%). The snails were exposed to a given dose for 24 hours. Twenty live snails from each dose or control group were collected and randomly divided into four replicate groups, each with five snails, for subsequent RNA extraction and transcriptome analysis

Project description:Ahead of display, a non-original layer was observed on the surface of a fragment of a wall painting by Ambrogio Lorenzetti (active 1319, died 1348/9). FTIR analysis suggested proteinaceous content. Mass spectrometry was used to better characterise this layer and revealed two protein components: sheep and cow glue and chicken and mallard egg white. Analysis of posttranslational modifications detected several photo-oxidation products, which suggest that the egg experienced prolonged exposure to UV-light and was likely applied long before the addition of the glue. Additionally, glycation products detected may indicate naturally occurring glycoprotein degradation or reaction with a carbohydrate material such as starch, identified by ATR-FTIR in a cross-section of a sample taken from the painting. Palaeoproteomics is shown to provide detailed characterisation of organic layers associated with mural paintings and therefore aids reconstruction of the conservation history of these objects.
Project description:Through thousands of years of breeding and strong human selection, the dog (Canis lupus familiaris) exists today within hundreds of closed populations throughout the world, each with defined phenotypes. A singular geographic region with broad diversity in dog breeds presents an interesting opportunity to observe potential mechanisms of breed formation. Italy claims 14 internationally recognized dog breeds, with numerous additional local varieties. To determine the relationship among Italian dog populations, we integrated genetic data from 263 dogs representing 23 closed dog populations from Italy, seven Apennine gray wolves. Using 142,840 genome-wide SNPs, this dataset was used in the identification of breed development routes for the Italian breeds that included divergence from common populations for a specific purpose, admixture of regional stock with that from other regions, and isolated selection of local stock with specific attributes.
