Palaeoproteomics and microanalysis reveal techniques of production of animal based metal threads in medieval textiles part II

ABSTRACT: Protein-based or animal-based metal threads were largely used between the 10th and the 15th centuries, in European, Middle Eastern and Far Eastern textile productions for the decoration of textiles and cloths to make a display of wealth, power and status. A total of 91 samples were collected from a corpus of 66 textile fragments belonging to 54 catalogued objects. Proteomics analysis allowed to determine the origin of the animal substrates, which were found to be from cattle membranes (possibly from gastrointestinal organs or bladder) in membrane strips, while in leather strips (possibly made from the corium or grain skin layer of the animals), goat (exclusively in Spanish samples) and sheep (in Middle Eastern/Italian and Far Eastern samples) were identified. Other protein-based components that made the strips were identified and associated to the adhesive binders.

Palmyrene Polychromy: Investigations of funerary portraits from Palmyra in the collections of the Ny Carlsberg Glyptotek

Project description:Two samples from the Beauty of Palmyra (IN 2795 – Ny Carlsberg Glyptotek, Copenhagen, Denmark) were collected from the surface coating, and partially the paint layer, in locations corresponding to paint residues from respectively the yellow paint (containing lead-based yellow pigment) and the red paint (containing haematite as pigment) of the headdress of the figure. The two samples were analysed using a palaeoproteomic protocol to investigate the use of a proteinaceous paint binder and/or the presence of other proteinaceous materials. The analysis led to the confident identification of collagen, probably indicating the use of animal glue as paint binder of the sample removed from red paint residues. Various animal keratins were also confidently identified in both samples. The presence of these proteins might be related to the manufacture of organic pigments, but also possibly to the use of a keratin-based glue as paint binder or surface coating, or even to the use of a paintbrush made with animal bristles.

Molecular Pathology of adverse local tissue reaction caused by metal-on-metal implants

Project description:RNA-sequencing analysis of periacetabular synovial tissue collected from patients undergoing a revision total hip arthroplasty (rTHA) after failure of a Cobalt Chromium implant. Comparisons were made to periacetabular synovial tissue collected from patients undergoing primary THAs (pTHA). Results: Analysis of tissue biopsies by RNA-sequencing revealed that MoM patient samples exhibit significantly increased expression of immune response genes but decreased expression of genes related to extracellular matrix (ECM) remodeling.

Human and animal skin identified by palaeoproteomics in Scythian leather objects from Ukraine

Project description:Leather was one of the most important materials of nomadic Scythians, who used it for clothing, shoes, and quivers, amongst other objects. However, we have little information about the animal species utilised for Scythian leather production. In this first systematic study, we used palaeoproteomics methods to analyse the species in 45 samples of leather and two fur objects recovered from 18 burials excavated at 14 different Scythian sites in southern Ukraine, 3 of which were analysed by LC-MS/MS. Our results demonstrate that Scythians primarily used domesticated species such as sheep, goat, cattle, and horse for the production of leather, while the furs were made of wild animals such as fox, squirrel and feline species. The surprise discovery is the presence of two human skin samples, which for the first time provide direct evidence of the Greek historian Herodotus’ claim that Scythians used the skin of their dead enemies to manufacture leather trophy items, such as quiver covers. We argue that leather manufacture is not incompatible with a nomadic lifestyle and that Scythians possessed sophisticated leather production technologies that ensured stable supply of this essential material.

Heavy metal-inducible gene expression in Hyphomonas neptunium

Project description:Hyphomonas neptunium proliferates by a unique budding mechanism in which daughter cells emerge from the end of a stalk‐like extension emanating from the mother cell body. Studies of this species have so far been hampered by the lack of a genetic system and of molecular tools allowing the regulated expression of target genes. Based on microarray analyses, this work identifies two H. neptunium promoters that are specifically activated by copper and zinc, respectively. Functional analyses show that they have low basal activity and a high dynamic range, thus meeting the requirements for use as a multi‐purpose expression system.

Species identification of archaeological skin objects from Danish bogs

Project description:Denmark has an extraordinarily large and well-preserved collection of archaeological skin garments found in peat bogs, dated to approximately 920 BC - AD 775. These objects provide not only the possibility to study prehistoric skin costume and technologies, but also to investigate the animal species used for production of skin garments. Until recently, species identification of archaeological skin was mainly performed by light and scanning electron microscopy or analysis of ancient DNA. However, the efficacy of these methods can be limited due to the harsh, mostly acidic environment of peat bogs leading to morphological and molecular degradation within the samples. We compared species assignment results of twelve archaeological skin samples from Danish bogs using Mass Spectrometry (MS)-based peptide sequencing, against results obtained using light and scanning electron microscopy

Tosini-1R01NS043459-01A1

Project description:It is well known that many genes are expressed in the retina where they show a clear daily pattern of expression. Although several studies have investigated gene expression in the retina, no study – so far - has investigated the daily and the circadian pattern of gene expression using microarray. In the present study we propose to investigate the daily and circadian pattern of expression in the retina. To determine gene expression in the retina in Light:Dark cycles and in constant condition (constant dim light) in the rat. We hypothesize that (a) different genes are expressed in different retinal layers and (b) the pattern of expression of the same genes can differ among the different layers. Wistar rats (3 for each time point) will be killed in the middle of the day (ZT6) and in the middle of the night (ZT18). Eyeballs will be collected and the retina will be removed and immediately frozen and then stored at -80 oC. The same experiment will be repeated on animals that have been maintained in constant dim light for 3. Retinas (3 for each time point) will be obtained from animal killed at CT6 (middle subjective day) and CT 18 (middle subjectice night) and stored at – 80 oC. The samples will be then shipped to NINDS-NIMH array facility for analysis. Keywords: time-course

Animal blood African arworks LC-MSMS

Project description:Multiple analytical techniques were used to characterize materials from the surfaces of two African sculptures in the collection of the Art Institute of Chicago: a Bamana power object (boli), and a Yoruba wooden sculpture of a female figure. Surface accretions on objects such as these have received relatively little scientific attention to elucidate their composition and function, in part because they are made with complex mixtures of natural materials, which are often unfamiliar and poorly represented in the scientific literature on artists’ materials. Mass spectrometry-based proteomics provided new insights on proteinaceous components, allowing us to identify the presence of sacrificial blood, and more specifically, blood from chicken, goat, sheep and dog. This new scientific evidence supports and supplements knowledge derived from curatorial and field work studies, and opens new doors to understanding the objects’ significance and history of use.

Extinct species identification from late Middle Pleistocene and earlier Upper Pleistocene bone fragments and tools not recognizable from their osteomorphological study by an enhanced proteomics protocol

Project description:Ancient preserved molecules offer the opportunity of gaining a deeper knowledge on their biological past. However, the development of a proteomic workflow remains a challenge. The analysis of fossils must involve a low quantity of material to avoid damaging the samples. In this study an enhanced proteomic protocol was applied to 5-milligram samples of about 130,000-year-old mammalian bones ranging from the end of the Middle Pleistocene up to the earlier Upper Pleistocene, excavated from Scladina Cave (Sclayn, Belgium). Using sequence homology with modern sequences, a biological classification was successfully achieved and the associated taxonomic ranks to each bone were identified consistently with the information gained from osteomorphological studies and palaeoenvironmental and palaeodietary data. Amino acid substitutions on collagens were identified, thus providing new information on extinct species sequences and helping in taxonomy-based clustering. Considering samples with no osteomorphological information, such as two bone retouchers, proteomics successfully identified the families providing paleontologists new information on these objects. Combining osteomorphology studies and amino acid variations identified by proteomics, one of the retouchers was potentially identified as belonging to the Ursus spelaeus species.
