The researchers then tested whether GRPR is required for feeling itchy by injecting several itch-inducing compounds into the knockout mice, including histamines--the substances responsible for the itchiness of allergies.
Recent reports suggest a stimulating antioxidative effect of cryostimulation but there is no information regarding the substances responsible for it (Miller et al. 2010a, b, c).
The capping agents can be also the substances responsible for the reduction of silver, or some other components present in the plants [8].
Saying in another way, it seems that the production and release of sepsis mediators should be considered as a network rather than as a cascade; consequently, once the process is started, even if one of the substances responsible for the initial phase is blocked, other mediators will likely maintain the septic response [43, 44].
On the one hand, the method represents a further step to the ultimate identification of the substances responsible for ice nucleation.
It is probable that at low dosages of the aqueous and methanol extracts of Ajuga remota, the substances responsible for K+- sparing effect might not reach sufficient concentration to exert the effect.
In contrast, attempts to isolate the substances responsible for plant intrinsic INA have been unsuccessful as they often resulted in a loss of activity or because solubilization proved difficult (Pearce 2001).
Saying in another way, it seems that the production and release of sepsis mediators should be considered as a network rather than as a cascade; consequently, once the process is started, even if one of the substances responsible for the initial phase is blocked, other mediators will likely maintain the septic response [ 43, 44].
Isotretinoin is a prescription medication that works by reducing your body's production of facial oil (sebum), one of the substances responsible for clogged pores that cause whiteheads.
The substance responsible for this effect was identified in 1998 by a team of researchers in New Jersey as proanthocyanidin, a chemical related to tannin.
