Kinetic interference upon embryo development

"Rethinking" embryo disposition upon divorce.

Bilirubin interference in kinetic creatinine determination.

194 CLINICAL CHEMISTRY, Vol. 25, No. 1, 1979 gas chromatography before and after acid (6 mol/L HC1) and alkaline (NaOH) hydrolysis. We frequently observe a peak in the lactic acid position after alkaline hydrolysis. After acid hydrolysis of the same urine no lactate isobserved, but a peak appears in the position of levulinic acid. The mass spectra of these two peaks were identical with those of...

Development of the Embryo

Until 1804, when Salisbury found that orchid seeds could germinate, the seeds were considered sterile. Much later, in 1889, Bernard's discovery of the special conditions necessary for their growth and development explained the lack of success in previous attempts to obtain plantules, and the success, although mediocre, when sowing of seed took place at the foot of the mother plant. Knowing the ...

Kinetic Investigation of Myeloperoxidase upon Interaction with Copper, Cadmium, and Lead Ions

Background: Myeloperoxidase (MPO), which is abundantly expressed in neutrophils, catalyzes the formation of a number of reactive oxidant species. However, evidence has emerged that MPO-derived oxidants contribute to tissue damage and initiation and propagation of inflammatory diseases, particularly, cardiovascular diseases. Therefore, studying the regulatory mechanisms of the enzyme activity is...

The action of various agents upon the rabbit embryo.

I N the course of an investigation on the uptake of labelled ions by the rabbit embryo and its environment (Lutwak-Mann, Boursnell, & Bennett, 1960), experiments were done on pre-implantation blastocysts obtained from rabbits which had been treated parenterally with certain purine analogues. Histological examination of such blastocysts by the method of Moog & Lutwak-Mann (1958) showed that, as ...
