La mezcla de residuos originados por los sistemas producción animal, que pueden incluir estiércol, aguas lavado, agua lluvia, restos alimento balanceado y desechos cama, han sido utilizados para mejorar la productividad las cosechas comúnmente se les denomina purines. El objetivo del presente estudio fue evaluar el efecto aplicación fertilizantes orgánicos e inorgánicos sobre composición químic...

Haloalkyl purines i.e. 2,6-diamino-8-(chloromethyl) purine 10; 2, 6-diamino-X- (chloromethyl) purine 17; 2,6-diamino-8-(chloropropylp) urine 18; were synthesized by two distinct but facile methods. The N-alkylating potential of 2, 6-diamino-8- (chloromethyl) purine was investigated. The following products 2,6-diamino-8-(Nbenzyl- N-methyl) purine 11; 2,6-diamino-8-(4-nitro anilinomethyl) pur...
Guanine-based purines have been traditionally studied as modulators of intracellular processes, mainly Gprotein activity. However, more recently, several studies have shown that they exert a variety of extracellular effects not related to G-proteins, including trophic effects on neural cells, modulation of glutamatergic activity, behavioral effects and anticonvulsant activity. In this article, ...
Excessive intake of purine-rich foods elevates serum levels of uric acid. Animal and fish meats contain high amounts of inosine and its related purines, and the reduction of taking those purines is crucial for the improvement of serum uric acid levels. We previously showed that Lactobacillus gasseri PA-3 (PA-3) incorporates adenosine and its related purines and that oral treatment with PA-3 red...
An HPLC method was developed to quantify the purines adenine and guanine and their metabolites xanthine and hypoxanthine in hydrolysates of isolated bacteria and omasal digesta and to assess the effect of using either purines only or purines plus metabolites as microbial markers for estimating microbial flow from the rumen. Individual purines and their metabolites were completely resolved on a ...
heat shock proteins (hsps), are highly important due to their association with such economically important traits in animals as resistance to temperature shock and mastitis. in the current study, to get a comprehensive information on molecular structure and evolution of the hsp70s, and the available hsp70 sequences of the cattle and other animals taken from ncbi and aligned together. then, nucl...
