Thermodynamics of the (lanthanum + strontium + copper + oxygen) high-Tc superconductors I. Heat capacities of SrCuO2, Sr2CuO3, and Sr14Cu24O41
(Elsevier, 1990-11)
The subambient heat capacities of three (SrO)x(CuO)y inter-oxide samples with x = Y = 1; x = 2, y = 1; and x = 1, y = 2, were measured as a part of an investigation into the chemical thermodynamics of the high-Tc superconducting ...
Glycosidases of ehrlich ascites tumor cells and ascitic fluid--Purification and substrate specificity of [alpha]-N-Acetylgalactosaminidase and [alpha]-galactosidase: Comparison with coffee bean [alpha]-galactosidase
(Elsevier, 1990-07)
Ehrlich ascites tumor cells and ascitic fluid were assayed for glycosidase activity. [alpha]-Galactosidase and [beta]-galactosidase, [alpha]- and [beta]-mannosidase, [alpha]-N-acetylgalactosaminidase, and [beta]-N-acetyl ...
(1E,3E)-4-acetoxy-1-phenyldimethylsilyl-1,3-butadiene as a surrogate for (1E,3E)-1,4- diacetoxy-1,3-butadiene: a highly efficient synthesis of (+/-)-shikimic acid
(Elsevier, 1990)
The 5-step synthesis of (+/-)-shikimic acid has been achieved in 55% overall yield from (1E,3E)-4-acetoxy-1-phenyldimethylsilyl-1,3-butadiene, starting with its Diels-Alder reaction with 2-(trimethylsilyl)ethyl acrylate ...
Controlled release implants for cardiovascular disease
(Elsevier, 1990-01)
The systemic therapy of many cardiovascular diseases is often hampered by adverse drug effects. The present paper examines the use of controlled release implants as a means for optimizing drug concentrations at the affected ...
DXS165 detects a translocation breakpoint in a woman with choroideremia and a de novo X; 13 translocation
(Elsevier, 1990-04)
The search for the gene for choroideremia (MIM 30310), a rare retinal dystrophy, has been of great interest due to the existence of several choroideremia patients with well-defined structural chromosome aberrations, thus ...
Kinetic studies of the deactivation of O 2 ( 1 Σ g + ) and O( 1 D)
(John Wiley & Sons, Inc., 1990-12)
The kinetics of the deactivation of O 2 ( 1 Σ g + ) is studied in real time. O 2 ( 1 Σ g + ) is generated in this system by the O( 1 D) + O 2 reaction following O 3 laser flash photolysis in the presence of excess ...
