The TM cells were treated with or without 25 [micro]M Y-27632 for 30 min, followed by menadione
stimulation of the cells for 24 h.
Thus, the increase in antioxidant defense as a result of mild oxidative stress can explain higher resistance of AKG-grown YPH250 cells to [H.sub.2][O.sub.2], menadione
, and [Fe.sup.2+] and [Cu.sup.2+] ions.

Serum glycoproteins in rats treated with high doses of vitamin [K.sub.3] (menadione
Procesamiento de las Muestras: para el aislamiento de las bacterias a partir de muestras de sangre (hemocultivo), se utilizo el metodo convencional (1), conformado por dos frascos: uno designado con la letra A, el cual contiene 50 mL de Caldo Soya Tripticasa y 15% de Sucrosa; y otro designado con la letra B conteniendo 100 mL de Caldo Thioglicolato, 0,025% de Liquoid y los suplementos hemina (0,5 mg/mL) y menadione
The researchers scanned lab-cultured liver cells as they encountered menadione
, an analog of a drug used against cancer.
Synthetic vitamin K is identified by the chemical name menadione
is extremely unstable, so pure vitamin K is not utilized in the feed industry.
were noncompetitive against NADPH and menadione
. However, at saturating levels of NADPH, bithionol sulfoxide inhibited to a lesser extent and bithionol was competitive against menadione
aureus small colony variants are characterized as electron transport deficient bacteria because of their auxotrophism to hemin or menadione
or are recognized as thymidine-dependent.
Vitamin K comprises three main forms: vitamin K1 or phylloquinone which is found in green plants; vitamin K2 or the menaquinone family which is synthesised by bacteria in the large intes tine; and vitamin K3 or menadione
which is a synthetic, water-soluble form that has been utilised in animal feeds.
