Familial transthyretin (TTR) amyloidosis commonly presents with peripheral neuropathy and involvement of visceral organs. In contrast, signs of central nervous system (CNS) involvement are exceptional. We report that members of a kindred affected by a slowly progressive dementia, seizures, ataxia, hemiparesis, and decreased vision without neuropathy have(More)
Type 2 diabetes is a complex disease in which genetic and environmental factors interact to produce alterations in insulin action and insulin secretion, leading to hyperglycemia. To evaluate the influence of genetic background on development of diabetes in a genetically susceptible host, we generated mice that are double heterozygous (DH) for knockout of(More)
Members of a German family living in Ohio (United States) have been found to have dominantly inherited amyloidosis causing dementia, seizures, strokes, coma and visual deterioration. Pathological examination of affected individuals has shown severe, diffuse amyloidosis of the leptomeninges and subarachnoid vessels associated with patchy fibrosis and(More)
Oxytocin has insulin-like activity in that it stimulates lipogenesis and increases pyruvate dehydrogenase activity. However, in adipocytes from homozygous Brattleboro rats oxytocin is incapable of stimulating lipogenesis or pyruvate dehydrogenase activity, although insulin stimulation of both processes is normal and the antilipolytic activity of oxytocin is(More)
Oxytocin initiates its insulin-like action in adipocytes through oxytocin-specific receptors. We have studied binding and structural properties of these receptors with the radioligand [3H]oxytocin. Steady-state binding was reached after 45 min, at 21 degrees C, and 10 min at 37 degrees C. Scatchard analyses of equilibrium binding data indicated a single(More)
Sleep apnea in association with neurologic disease is uncommon, and its documentation with nocturnal polysomnography (PSG) is rare. Two patients with posterior fossa neurologic disease had obstructive and central sleep apnea on PSG. The first was a 40-year-old woman who experienced a respiratory arrest ten days after neurosurgical decompression of a(More)
We have investigated the effects of adenosine on the stimulation of glucose oxidation and lipogenesis by oxytocin and insulin in rat epididymal adipocytes. The addition of adenosine deaminase (1 U/ml) to the assay medium reduced the maximal oxytocin response (glucose oxidation and lipogenesis) to between 25 and 50% of the maximum response in control cells.(More)
A game is introduced and experimented that allows for a direct comparison of the two predominant equilibrium concepts of economic theory: the competitive versus the strategic equilibrium. Neither of the two extreme and completely disjoint equilibrium predictions fully explains the data. Observed outcomes, however, are closer to the competitive than the(More)
Using laser beam immunonephelometry, we confirmed the value of Tourtellotte's formula in the diagnosis of MS. Moreover, since immunonephelometry presents several advantages, including simplicity, rapidity, and precision, it is a promising technique for the diagnosis of MS. Complicated measurements are not necessary. Determinations take only minutes. The(More)
To measure myelin basic protein (MBP)-like material in cerebrospinal fluid, we compared two radioimmunoassays, both using the same antiserum to MBP but one using peptide (45-89) as the radioligand and standard (peptide assay), and the other using purified MBP as the radioligand and standard (MBP assay), with respect to their diagnostic sensitivity.(More)
