A metabolic system-wide characterisation of the pig: a model for human physiology

The pig is a single-stomached omnivorous mammal and is an important model of human disease and nutrition. As such, it is necessary to establish a metabolic framework from which pathology-based variation can be compared. Here, a combination of one and two-dimensional (1)H and (13)C nuclear magnetic resonance spectroscopy (NMR) and high-resolution magic angle spinning (HR-MAS) NMR was used to provide a systems overview of porcine metabolism via characterisation of the urine, serum, liver and kidney metabolomes. The metabolites observed in each of these biological compartments were found to be qualitatively comparable to the metabolic signature of the same biological matrices in humans and rodents. The data were modelled using a combination of principal components analysis and Venn diagram mapping. Urine represented the most metabolically distinct biological compartment studied, with a relatively greater number of NMR detectable metabolites present, many of which are implicated in gut-microbial co-metabolic processes. The major inter-species differences observed were in the phase II conjugation of extra-genomic metabolites; the pig was observed to conjugate p-cresol, a gut microbial metabolite of tyrosine, with glucuronide rather than sulfate as seen in man. These observations are important to note when considering the translatability of experimental data derived from porcine models.

Assessing hepatic metabolic changes during progressive colonization of germ-free mouse by 1H NMR spectroscopy

It is well known that gut bacteria contribute significantly to the host homeostasis, providing a range of benefits such as immune protection and vitamin synthesis. They also supply the host with a considerable amount of nutrients, making this ecosystem an essential metabolic organ. In the context of increasing evidence of the link between the gut flora and the metabolic syndrome, understanding the metabolic interaction between the host and its gut microbiota is becoming an important challenge of modern biology.1-4 Colonization (also referred to as normalization process) designates the establishment of micro-organisms in a former germ-free animal. While it is a natural process occurring at birth, it is also used in adult germ-free animals to control the gut floral ecosystem and further determine its impact on the host metabolism. A common procedure to control the colonization process is to use the gavage method with a single or a mixture of micro-organisms. This method results in a very quick colonization and presents the disadvantage of being extremely stressful5. It is therefore useful to minimize the stress and to obtain a slower colonization process to observe gradually the impact of bacterial establishment on the host metabolism. In this manuscript, we describe a procedure to assess the modification of hepatic metabolism during a gradual colonization process using a non-destructive metabolic profiling technique. We propose to monitor gut microbial colonization by assessing the gut microbial metabolic activity reflected by the urinary excretion of microbial co-metabolites by 1H NMR-based metabolic profiling. This allows an appreciation of the stability of gut microbial activity beyond the stable establishment of the gut microbial ecosystem usually assessed by monitoring fecal bacteria by DGGE (denaturing gradient gel electrophoresis).6 The colonization takes place in a conventional open environment and is initiated by a dirty litter soiled by conventional animals, which will serve as controls. Rodents being coprophagous animals, this ensures a homogenous colonization as previously described.7 Hepatic metabolic profiling is measured directly from an intact liver biopsy using 1H High Resolution Magic Angle Spinning NMR spectroscopy. This semi-quantitative technique offers a quick way to assess, without damaging the cell structure, the major metabolites such as triglycerides, glucose and glycogen in order to further estimate the complex interaction between the colonization process and the hepatic metabolism7-10. This method can also be applied to any tissue biopsy11,12.

Playing with history: negotiating subjectivity in contemporary lens based work

Contemporary artists exploring Jewish identity in the UK are caught between two exclusions, broadly speaking: an art community that that sees itself as ‘post –identity’ and a ‘black’ art scene that revolves around the organizations that emerged out of the Identity debates of the 1980s and 1990s, namely Iniva, Third Text, Autograph. These organizations and those debates, don’t usually include Jewish identity within their remit as Jewish artists are considered to be well represented in the British art scene and, in any case, white. Out of these assumptions, questions arise in relation to the position of Jews in Britain and what is at stake for an artist in exploring Jewish Identity in their work. There is considerable scholarship, relatively speaking on art and Jewish Identity in the US (such as Lisa Bloom; Norman Kleeblatt; Catherine Sousslouf), which inform the debates on visual culture and Jews. In this chapter, I will be drawing out some of the distinctions between the US and the UK debates within my analysis, building on my own writing over the last ten years as well as the work of Juliet Steyn, Jon Stratton and Griselda Pollock. In short, this chapter aims to explore the problematic of what Jewish Identity can offer the viewer as art; what place such art inhabits within a wider artistic context and how, if at all, it is received. There is a predominance of lens based work that explores Identity arising out of the provenance of feminist practices and the politics of documentary that will be important in the framing of the work. I do not aim to consider what constitutes a Jewish artist, that has been done elsewhere and is an inadequate and somewhat spurious conversation . I will also not be focusing on artists whose intention is to celebrate an unproblematised Jewishness (however that is constituted in any given work). Recent artworks and scholarship has in any case rendered the trumpeting of attachment to any singular identity anachronistic at best. I will focus on artists working in the UK who incorporate questions of Jewishness into a larger visual enquiry that build on Judith Butler’s notion of identity as process or performative as well as the more recent debates and artwork that consider the intersectionality of identifications that co-constitute provisional identities (Jones, Modood, Sara Ahmed, Braidotti/Nikki S Lee, Glenn Ligon). The case studies to think through these questions of identity, will be artworks by Susan Hiller, Doug Fishbone and Suzanne Triester. In thinking through works by these artists, I will also serve to contextualise them, situating them briefly within the history of the landmark exhibition in the UK, Rubies and Rebels and the work of Ruth Novaczek, Lily Markewitz, Oreet Ashery and myself.

Arcangela Tarabotti: una famiglia non detta e un segreto indicibile in famiglia

This article contains an exhaustive research done on archives sources regarding the Venetian suor Arcangela Tarabotti's family. The eldest of seven girls, she was compelled to enter the cloister in 1620. Despite she includes only two letters agmong the 256 she managed to publish in her collection, her siblings had destinies that stayed intertwined with her own. In particular, because her family had, most probably a past as a Jewish new converted family, something that explains some unusual patterns within the Tarabotti family itself.

Insights into the molecular architecture of a peptide nanotube using FTIR and solid-state NMR spectroscopic measurements on an aligned sample

The self-assembly of proteins and peptides into b-sheet-rich amyloid fibers is a process that has gained notoriety because of its association with human diseases and disorders. Spontaneous self-assembly of peptides into nonfibrillar supramolecular structures can also provide a versatile and convenient mechanism for the bottom-up design of biocompatible materials with functional properties favoring a wide range of practical applications.[1] One subset of these fascinating and potentially useful nanoscale constructions are the peptide nanotubes, elongated cylindrical structures with a hollow center bounded by a thin wall of peptide molecules.[2] A formidable challenge in optimizing and harnessing the properties of nanotube assemblies is to gain atomistic insight into their architecture, and to elucidate precisely how the tubular morphology is constructed from the peptide building blocks. Some of these fine details have been elucidated recently with the use of magic-angle-spinning (MAS) solidstate NMR (SSNMR) spectroscopy.[3] MAS SSNMR measurements of chemical shifts and through-space interatomic distances provide constraints on peptide conformation (e.g., b-strands and turns) and quaternary packing. We describe here a new application of a straightforward SSNMR technique which, when combined with FTIR spectroscopy, reports quantitatively on the orientation of the peptide molecules within the nanotube structure, thereby providing an additional structural constraint not accessible to MAS SSNMR.
