Interleukin-6 (IL6) is critically involved in inflammation and metabolism. About 1% of people produce IL6 autoantibodies (aAb-IL6) that impair IL6 signaling in vivo. We tested the hypothesis that the prevalence of such aAb-IL6 is increased in type 2 diabetic patients and that aAb-IL6 plays a direct role in causing hyperglycemia. In humans, the prevalence of(More)
Following intratracheal injection of particles of colloidal gold (30 nm) in the rat, particles in the blood platelets of the alveolar capillaries can rapidly be observed. The presence of the gold is confirmed by microanalysis. The role of this phenomenon in pulmonary clearance is discussed.
It has been suggested that in uremic bone, aluminum interferes with normal mineralization. Aluminum content and aluminum localization were studied in iliac crest biopsies of two groups of patients on regular hemodialysis; one group had histologic osteomalacia, and little or no bone resorption (group 1); the other, osteitis fibrosa and no mineralization(More)
There have been numerous reports suggesting that human peripheral blood mononuclear cells (PBMCs) can be productively infected with human hepatitis B virus (HBV). We therefore examined whether the PBMCs can be used to establish an in vitro infection system for HBV. Freshly purified PBMCs were incubated with HBV with or without mitogen stimulation.(More)
Some nickel compounds (Ni3S2,Ni) induce tumours in muscle, while others have no effect (NiO). It has been suggested that the carcinogenicity of nickel is related to its penetrating power (phagocytosis) in transformed cells. The penetration of various nickel salts into cultured rhabdomyosarcoma cells (RhC) was studied. Electron microscopy and microanalysis(More)
BACKGROUND Parathyroidectomy is unsuccessful in 10-30% of uraemic patients operated on for secondary hyperparathyroidism. We investigated the usefulness of preoperative radionuclide imaging, with simultaneous recording of the distribution images of iodine-123 and technetium-99m-labelled sestamibi. METHODS 11 patients with secondary hyperparathyroidism(More)
The progressive transformation of illite crystals in alveolar macrophages has been studied with x-ray microanalysis and electron microdiffraction. Illite particles captured by macrophages undergo a series of progressive modifications which affect their ultrastructure, crystalline state, and chemical composition. Crystalline structure progressively(More)
CONCLUSION Anti-p53-autoantibodies (a-p53-aabs) may suppress the development of distant metastases, but not lymph node metastases. This could explain the significantly prolonged survival of patients with UICC stage III tumors who have a-p53-aabs compared to those without a-p53-aabs. BACKGROUND Mutation within the tumor suppressor gene p53 leads to(More)
