Seco-, nor-, normal and rearranged labdanes from Haplopappus parvifolius
(1991)
The aerial parts of Haplopappus parvifolius afforded 30 new diterpenes including 21 labdane derivatives, four nor-diterpenes, three rearranged ones, four seco-labdanes and one with a new carbon skeleton whose structure was ...
Similarities and differences among the chromosomes of the wild guinea pig Cavia tschudii and the domestic guinea pig Cavia porcellus (Rodentia, Caviidae)
(Pensoft Publ, 2014)
Cavia tschudii Fitzinger, 1867 is a wild guinea pig species living in South America that according to the analysis of mitochondrial genes is the closest wild form of the domestic guinea pig. To investigate the genetic ...
Diterpenes and umbelliferone derivatives from Haplopappus deserticola
(1990)
The aerial parts of Haplopappus deserticola afforded three ent-labdane and one labdane derivative as well as a nor-ent-labdane. Furthermore, in addition to three known umbelliferone derivatives, a dimeric coumarin was ...
Synthesis and Dopamine Receptor Selectivity of the Benzyltetrahydroisoquinoline, (R)-(+)-nor-Roefractine
(American Chemical Society and American Society of Pharmacognosy, 1998-01-15)
(R)-(+)-nor-Roefractine (1) was synthesized
by the Bischler-Napieralski route, using asymmetric
reduction of the 1,2-didehydro precursor imine with
sodium (S)-N-CBZ-prolinyloxyborohydride. Compound
1 was able to displace ...
Genomic compatibility between two phyllotine rodent species evaluated through their hybrids
(1999)
In order to investigate the genomic compatibility between allopatric rodent species, Phyllotis durivini and Pliyllotis
mugister, we have studied several cytogenetic and reproductive features of their laboratory hybrids. ...

Copper Supplementation at 8 mg Neither Affects Circulating Lipids nor Liver Function in Apparently Healthy Chilean Men
(Springer, 2013)
Copper (Cu) deficiency has been reported to influence
lipid metabolism, but the effects in humans are controversial.
To evaluate the effects of 8 mg Cu/day supplementation
(as copper sulfate) for 6 months on the lipid ...
Electrochemical study, on mercury, of a Meta-nitroarylamine derivative of nor-β-lapachone, an antitumor and trypanocidal compound
(2010)
The electrochemistry of 2,2-dimethyl-(3H)-3-(N-3'-nitrophenylamino) naphtho[1,2-b]furan-4,5-dione ([Q]-PhNO2), on mercury was investigated. The first peak is consistent with a quasi-reversible one-electron reduction of the ...
Episodios de reactivación del sistema de fallas del Romeral en la parte Nor-Occidental de los Andes Centrales de Colombia a través de resultados 39AR-40AR y K-AR.
(Universidad Nacional de Colombia Sede Medellín. Facultad de Minas. Escuela de Geociencias y Medio Ambiente, 2012-12)
Direct dating of reactivation of the San Jerónimo Fault (SJF), easternmost limit of the Romeral fault system (RFS), is presented through 39Ar-40Ar and K-Ar results in neo-formed micas and mylonitic bands of strongly ...
Number and nuclear localisation of nucleoli in mammalian spermatocytes
(2004)
In seven mammalian species, including man, the position and number of nucleoli in pachytene spermatocyte nuclei were studied from electron microscope (EM) nuclear sections or bivalent microspreads. The number and position ...
