Increased recombination adjacent to the Huntington disease-linked D4S10 marker
(Elsevier, 1991-01)
Huntington disease (HD) is caused by a genetic defect distal to the anonymous DNA marker D4S10 in the terminal cytogenetic subband of the short arm of chromosome 4 (4p16.3). The effort to identify new markers linked to HD ...
Pathway of formation and catalase activity in a dioxo bridged Mn(IV) dimer.
(Elsevier, 1991-08)
The in vitro effects of metal cations on eukaryotic cell metabolism
(John Wiley & Sons, Inc., 1991-09)
The in vitro cytotoxicity of nine metal cations common in dental casting alloys was evaluated using Balb/c 3T3 fibroblasts and four toxicity parameters: total protein production, 3 H-leucine incorporation, 3 H-thymidine ...
Neopentane reactions over bimetallic Pt---Sn/AI2O3 and Pt---Au/SiO2 catalysts
(Elsevier, 1991-12)
The reaction of 2,2-dimethylpropane (neopentane) with hydrogen was studied over two series of supported bimetallic catalysts containing platinum as the primary group VIII metal and either gold or tin as the second metallic ...
A chemisorption and XPS study of bimetallic Pt-Sn/Al2O3 catalysts
(Elsevier, 1991-01)
Bimetallic Pt-Sn/Al2O3 catalysts with nominally 1 wt% Pt and varying tin contents (0-3.25 wt%) prepared by coimpregnation of nonporous Degussa alumina were characterized by chemisorption of H2, O2, and CO at room temperature. ...
Characterization of [beta]-endorphin-related peptides in the caudal medulla oblongata and hypothalamus of the prenatal, postnatal and adult rat
(Elsevier, 1991-09-19)
A comparison was made of [beta]-endorphin (B-END) concentrations versus post-translation products during the perinatal period in the hypothalamus and the caudal medulla oblongata. The concentration of B-END-like immunoreactivity ...
Phaeochromocytoma and functioning paraganglioma in childhood and adolescence: role of iodine 131 metaiodobenzylguanidine
(Springer-Verlag, 1991-03)
Phaeochromocytomas and functioning paragangliomas are rare tumours in childhood and adolescence. We review our experience of 43 cases (24 men, 19 women) who were first diagnosed at the age of ⩽ 18 years. All patients were ...
Gated cardiac blood pool studies in atrial fibrillation: role of cycle length windowing
(Springer-Verlag, 1991-01)
Cycle length windowing is gaining increasing acceptance in gated blood pool imaging of patients with atrial fibrillation (AF). The goals of this study were: to assess differences of ejection fraction (EF) in AF with and ...
