Patent number: 8961179Abstract: An apparatus and method for mineralising demineralised and hypo-mineralised biological material such as tooth or bone. The apparatus has a probe electrode for receiving a mineralisation agent and a counter electrode. It is also provided with a controller to control the electrical signal provided to the probe such that the extent of mineralisation of the biological material is controlled by modulating or changing the electrical signal provided by the probe based upon the measured output of the circuit formed from the probe, counter electrode and biological material. The electrical output provides a measure of the extent of mineralisation of the biological material which is compared with data from a reference technique which gives 3D structural information on an area of interest in the biological material.Type: GrantFiled: August 18, 2009Date of Patent: February 24, 2015Assignees: The University of Dundee, The University of Abertay, Dundee, The University Court of the University of St. AndrewsInventors: Christopher Longbottom, Joseph Crayston, Nigel Berry Pitts, Dmitri Grinev, Iain Young

Publication number: 20140187945Abstract: An ultrasound probe (10) comprises a pair of one dimensional transducer modules (1, 2) arranged in-line but set apart from each other in a shallow “V” shape. This allows a wide gap for needle manipulation while maintaining the ability to compute a good acoustic image of the target area (4) on an ultrasound scan engine. The ultrasound image is a product of data from both the arrays. The probe (10) is shaped to allow ergonomic manipulation possibilities for the anaesthetist. The probe can be held in a ‘pencil-type’ grip anywhere on the main body, or by pushing directly on the back of arrays. The shape of the probe, means it sits in position better on a patient than a conventional probe.Type: ApplicationFiled: August 24, 2012Publication date: July 3, 2014Applicant: UNIVERSITY OF DUNDEEInventors: Cochran Sandy, Roderick Habeshaw, Graeme McLeod, George Corner, Jonathan Marsh

Publication number: 20140121128Abstract: It is described the influence of the presence of mutations in the TP53 gene in association with high levels of the enzyme prolyl isomerase Pin1 and a molecular signature of 10 genes expression correlated with the expression of Pin1 and p53 for the prognosis of breast tumors. The association between overexpression of Pin1 and the presence of protein p53 mutants induces transcriptional programs which promote tumor aggressiveness and in a cohort of patients the overexpression of Pin1 has proved to influence the prognostic value of the presence of mutations in the gene TP53. The assessment of the expression of Pin1 in the presence of mutations of the gene TP53, together with the detection of the expression of the genes forming the molecular signature can therefore be used for the prognosis of breast cancer.Type: ApplicationFiled: June 15, 2012Publication date: May 1, 2014Applicants: University of Dundee, Universita Degli Studi di TriesteInventors: Giannino del Sal, Marco Napoli, Javier Girardini Brovelli, Silvano Piazza, Alastair Thompson

Publication number: 20140104678Abstract: The present invention uses nonlinear crystal waveguides to provide a continuous wave and picoseconds pulse laser systems that gives an order-of-magnitude increase in IR-to-visible conversion efficiency and also provide an order-of-magnitude increase of wavelength range for SHG conversion. The idea of enabling such broad tunability is based on the utilization of a significant difference in the effective refractive indices of the high order and low order modes in the waveguide. This feature enables the difference between the effective refractive indices of the fundamental and second-harmonic waves to be shifted to match the period of poling in a very broad wavelength range.Type: ApplicationFiled: April 10, 2012Publication date: April 17, 2014Applicant: UNIVERSITY OF DUNDEEInventors: Edik Rafailov, Ksenia Fedorova, Grigorii Sokolovskii

Publication number: 20140016185Abstract: A mode locked semiconductor disk laser with an output beam having an ultra-short pulse length which provides the incident beam to a non linear microscope. The wavelength of the beam is at or near the action cross section maximum absorption wavelength for creating two photon excited fluorescence of a fluorescent biological marker in a sample. Semiconductor disk lasers combine excellent beam quality and output power, stability while maintaining simplicity and easiness of operation. In addition, these types of lasers are ideally suited for mass production as they are built in wafer-scale technology enabling a high level of integration. Importantly this non expensive, turn-key, compact laser system could be used as a platform to develop portable non-linear bio-imaging devices for clinical studies, facilitating its wide-spread adoption in “real-life” applications.Type: ApplicationFiled: September 19, 2011Publication date: January 16, 2014Applicant: THE UNIVERSITY OF DUNDEEInventors: Craig Hamilton, Graeme Malcolm, Ursula Keller, Thomas Sudmeyer, Kurt Weingarten, Pablo Loza-Alvarez, Yohan Barbarin, Edik Rafailov
