Nuclear Magnetic Resonance (NMR) is a crucial experimental technique for the study of matter in several fields and applications, as for example in physics, chemistry, materials science, biology, medicine and food science. By means of this technique, the NMR group of the University of Pavia (UniPV) has given valuable scientific contributions to the Condensed Matter Physics and to the Physics applied to the Biomedical sector. In this note we’ll illustrate some of the most relevant results produced by the researchers of the group within decades of work carried out with passion and dedication, with examples regarding the Molecular Magnets, the High Tc Superconductors, the contrast agents and the hyperpolarization of molecules for Magnetic Resonance Imaging. We’ll also report some preliminary results obtained at the Preclinical Imaging Facility of UniPV, recently founded with the key contribution of the NMR group.

Determination of the microstructure and microchemistry of small features often provides the insight needed for the understanding of processes in real materials. In many cases, it is not adequate to use microscopy alone. Microdiffraction and microspectroscopic information such as EELS, X-ray microprobe analysis and Auger spectroscopy can all contribute vital parts of the picture. For a number of reasons, dedicated STEM offers considerable promise as a quantitative instrument. In this paper, we review progress towards effective quantitative use of STEM with illustrations drawn from studies of high Tc superconductors, compound semiconductors and metallization of H-terminated silicon.Intrinsically, STEM is a quantitative instrument. Images are acquired directly by detectors in serial mode which is particularly convenient for digital image acquisition, control and display. The VG HB501A at Cornell has been installed in a particularly stable electromagnetic, vibration and acoustic environment. Care has been paid to achieving UHV conditions (i.e., 10-10 Torr). Finally, it has been interfaced with a VAX 3200 work station by Kirkland. This permits, for example, the acquisition of bright field (or energy loss) images and dark field images simultaneously as quantitative arrays in perfect registration.

Paramagnetic polyoxometalates are of special interest with regard to their application as alternative contrast agents in nonhuman magnetic resonance imaging which is increasingly used in materials science and process engineering.

Brian Worthington was born into modest circumstances in Oldham and attended the local primary school, from which he moved to Hulme Grammar School, where he studied until he was 18 years of age. He was academically talented and attained the standard to enter university and indeed medical school with a scholarship to Guy’s Hospital in London. He graduated in physiology and medicine and was drawn towards radiology and in particular neuroradiology. He became a consultant for the Nottingham and Derby hospitals, but followed that with a university career as a Professor of Diagnostic Radiology at the University of Nottingham. He was a pioneer in clinical magnetic resonance imaging, for which he was honoured in many ways. Moreover, Brian Worthington was fascinated in all things Icelandic and became a fluent speaker in that language. With his wife Margaret and two sons, Andrew and Stuart, he maintained a close family relationship with his parents.

Abstract THIS ARTICLE REPRESENTS the first of a 2-part exploration of quantum dots (Qdots) and their application to neurological surgery. Spanning from materials science to immunology, this initial review traces the marriage of imaging physics to biochemical specificity. Qdot science now stands poised to dramatically advance the diagnosis and therapy of neurosurgical conditions. Qdot research efforts currently involve several disciplines; this comprehensive review therefore considers multiple fields of inquiry. This first installment discusses 1) Qdot physical properties, 2) established biological and in vivo properties, 3) magnetic resonance imaging applications, and (4) existing cardiovascular and oncologic research. Finally, this review establishes the existing bounds of Qdot possibilities. The second concept article details future endovascular diagnostic and therapeutic methods derived from these seminal advances.

Background: The diagnostic certainty of medullar tuberculosis (TB) without Pott disease is difficult to establish in a tropical environment with the large group of infectious, parasitic, and systemic myelopathies, despite the increasing availability of magnetic resonance imaging (MRI) data and improvement of biological exploration platforms. Methods: We retrospectively analyzed the files of 186 patients hospitalized in the Department of Neurology and Neurosurgery of the University Hospital Center of Conakry, Guinea, between 2008 and 2016 for the management of non-compressive and compressive myelopathy. Biological evidence of TB infection was demonstrated for 13 (6.9%) patients.  Results: Infectious clinical picture prior to the development of neurological signs was reported in 11 patients (84.6%). The neurological signs were summed up by the existence of a sensitivo-motor semiology of progressive evolution (100% of cases) with sphincter disorders in 11 patients (84.6%) and a medullary compression symptomatology with a lesion and under lesion syndrome from the outset in 4 patients (30.8%). Medullary MRI revealed an extensive intramedullary hypersignal in 9 patients with non-compressive myelopathy and in 4 cases, the lesions appeared in T1 hypersignal and T2 isosignal were localized. Lumbar puncture (LP) revealed lymphocytic pleocytosis, hypoglucorrhage (0.3 to 0.5 g/l), and leukocytosis. Conclusion: This study reveals a classic clinical, biological, neuroradiological, and evolutionary profile of compressive and non-compressive myelopathies. These results are important for the  therapeutic and evolutionary discussion of TB myelopathies for good management.
