About Elpida Hadzi-Vasileva

Elpida Hadzi-Vasileva
 is a site-specific installation artist working across the varied media of sculpture, installation, video and sound, photography and architectural interventions. Her materials range from the unusual to the ordinary and the ephemeral to the precious; they include organic materials, foodstuffs and precious metals. Central to her practice is a response to the particularities of place; its history, locale, environment and/or communities.
Over the past ten years, she has exhibited extensively and realized numerous commissions nationally and internationally, in gallery spaces, museums and within the public realm. Recent sites and commissions include Pied à Terre, London; Gloucester Cathedral, Gloucester; Towner Gallery, Eastbourne; Southgate Shoping Centre, Bath; Kilmainham Gaol Museum, Ireland; ArtSway at 51st Venice Biennale and Public Room, Skopje. She graduated in Sculpture from Glasgow School of Art, Glasgow in 1996 and the Royal College of Art, London, in 1998. Elpida Hadzi-Vasileva has been selected by the Minstry of Culture of Macedonia to represent Macedonia at the forthcoming 55th International Art Exhibition, La Biennale di Venezia, working with the National Gallery of Macedonia, this summer. Elpida is also currently developing a new commission for mima and Engage as part of the Alexandra Reinhardt Memorial Award Artist Residency and a new work for the artSOUTH project at Mottisfont Abbey. She is also developing a new art and medicine project with Dr. Richard Day and Professor Alastair Forbes at University College Hostpital, London.

Wellcome – Motilent

Last image shows a single time point from the dynamic series. Using powerful computer algorithms Motilent can quantify the motion caused by bowel motility to produce ‘motility maps’ (grayscale second image) and in colour (third image) where red shows areas of high motion and blue areas where there is low motility. First image is a fused image showing both the motility map and anatomy.

Wellcome- High resolution manometry

High resolution, invasive, optical manometry that detects pressure changes inside the bowel.

(A) A condensed manometric recording of the colon of a single subject over a 2-h period (1 h before and after a meal). The white line in the middle of the trace shows where the subject started the meal. Note the rapid increase in number of pressure events after the meal. (B) It is an enlargement of the red hatched box in A. Numerous retrograde cyclic propagating motor patterns are visible; they clearly comprise majority of the increased contractile activity induced by the meal. (C) It shows the same data as seen in B, but shown as a traditional low-resolution trace (lines spaced at 7 cm). All propagation is lost and these data would have been labeled as ‘non-propagating’.

Neurogastroenterology and Motility

Wellcome – High resolution manometry

High resolution, invasive, optical manometry that detects pressure changes inside the bowel.

Examples of the five main types of propagating motor pattern identified by visual inspection of multi-channel manometric traces. (A) High-amplitude propagating sequence; (B) cyclic propagating motor pattern, in this instance propagating in an retrograde (oral) direction (blue arrow); (C) short single propagating motor pattern – in this case moving in a retrograde direction (blue arrow); (D) long single propagating motor pattern – all of these moved in an antegrade (anal) direction (blue arrow). (E) Slow retrograde propagating motor pattern (blue arrow), which was only observed in two subjects, and only during the fasted state.

Wellcome – Motilent

GIQuant is Motilent’s bowel motility analysis technology that allows objective, quantitative analysis of MRI motility images. The grid represents ‘deformation fields,’ a mathematical description of how the bowel is moving. Areas of greater deformation correspond to higher motility and vice versa. GIQuant has been used to demonstrate motility changes arising from pathology in a range of conditions like Crohn’s disease.
