pka=−log(ka)andpkb=−log(kb) We can show the acid and its conjugate base dissociation reaction as followed Acid dissociation reaction: Let's assume HA is a weak acid. HA(aq)+H2O(l)→A−(aq)+H3O+(aq) ka=[A−][H3O+][HA] ...
Only in a few cases has it been demonstrated that a plant hormone is synthesized in the same cells where its function is required, and these may not require intercellular transport mechanisms. A well-documented example regards ABA. Guard cells are able to synthesize ABA autonomously upon drought,...
Most venomous snakes belong to the elapid or viperid families. In general, the elapid venoms comprise toxins affecting the nervous system and are considered as neurotoxic, while the action of viperid venoms is directed mainly on blood coagulation and they are regarded as hemotoxic. The venoms ...
The real impact of nanoparticles on male fertility is evaluated after a careful analysis of the available literature. The first part reviews animal models to understand the testicular biodistribution and biopersistence of nanoparticles, while the second part evaluates their in vitro and in vivo biotoxi...
In fact, the French name of the sport is concours complet: the complete contest. Eventing demands equine attributes similar to those of a warhorse: obedience, agility and grace on parade (represented by the dressage phase), courage, strength, fitness and speed in battle (the cross-country ...
Hydroxysteroid 11-beta dehydrogenase 1 (HSD11B1) catalyzes the bidirectional reaction of the conversion of cortisol to cortisone. The activity of this enzyme is impaired in hyperglycemic conditions [35]. Interleukin-19 (IL19) is a cytokine that can bind the IL20 receptor complex and lead to ...
