The magnetic field dependence of 1/T1 over the range 0.01 to 50 MHz proton Larmor frequency (NMRD profile) is reported for water protons in solutions of horse spleen apoferritin, and of ferritin reconstituted at both low and high iron levels. The apoferritin results are in every way typical of diamagnetic spherical proteins of their size (K. Hallenga and S.… (More)
Two cases of aseptic meningitis occurred in temporal association with high dose intravenous immunoglobulin therapy to treat thrombocytopenia. In neither case was any other aetiological agent identified and both patients completely recovered within a few days. This phenomenon has been reported in only one previous paediatric case.
Despite improved outcomes in multiple myeloma (MM), a cure remains elusive. However, even before the current therapeutic era, 5% of patients survived >10 years and we propose that immune factors contribute to this longer survival. We identified patients attending our clinic, who had survived >10 years (n=20) and analysed their blood for the presence of… (More)
The myeloma plasma cell is a postgerminal center, isotype-switched B cell. Chromosomal translocations into immunoglobulin heavy chain (IgH) switch regions, recombination sites in isotype switching, were initially demonstrated in myeloma cell lines but only a limited number of primary tumors. Molecular cytogenetics have since been applied to a series of… (More)
UVB light is considered the major environmental inducer of human keratinocyte (KC) DNA mutations, including within the tumor-suppressor gene p53, and chronic exposure is associated with cutaneous squamous cell carcinoma formation. Langerhans cells (LCs) comprise a dendritic network within the suprabasilar epidermis, yet the role of LCs in UVB-induced… (More)
Gamma-delta T-cell lymphomas (GD-TCL) are rare and rapidly fatal neoplasms that are often associated with Hemophagocytic Lymphohistiocytosis (HLH), a syndrome of fevers, cytopenias, and multiorgan failure that often leads to a rapid death. We report the first case demonstrating an association between GD-TCL, HLH, and cardiac amyloidosis, presenting a novel… (More)
