La formation de pigment dans les cultures de Bacillus subtilis sur pomme de terre

, : La formation de pigment dans les cultures de Bacillus subtilis sur pomme de terre. Compt Rend Soc Biol 128(18): 360-362

Addition of minerals to media shows that the pigment formation of B. subtilis on potato is related to its mineral content, particularly iron. The ions of SO4 favor pigment formation, those of Cl- and NO2- inhibit it.

The activation of Ca(2+)-dependent Cl(-) channels during norepinephrine-induced contraction of vascular smooth muscle was suggested to depolarize cell membrane and to increase Ca(2+) entry. Hypertension and ageing are associated with altered Ca(2+...

Reliability of Hakki's formula. The severity of aortic valve stenosis should be assessed by means of the calculation of the valvular area; on the other hand, the routine use of the Gorlin's formula for the aortic area is laborious and time consuming. Recently Hakki proposed...

To investigate the effects of temperature and light on germination of Lavandula stoechas, seeds were incubated at 5, 10, 15, 20, 25, 30 and 35 degrees C in dark or light (12 h) conditions for 25 days. Seeds incubated 5, 30 and 35 degrees C, under...

Patients with intercostal nerve blockade had significantly less pain at 0, 4, 8 and 12 h af...
