this study was conducted to determine the chemical composition, digestibility, degradability and nutritive value of madder, rubia tinctorum l.  and alfalfa medicago sativa. using in vitro and in situ measurements. the mean values for om, cp, ndf, adf and ee were 892.5, 172.0, 306.5, 219.4 and 16.0 g/kg dm for madder hay, and 921.3, 141.4, 482.0, 361.1 and 6.50 g/kg dm for alfalfa hay, respectiv...

the aim of this work was to investigate the effect of silica coating on bioactivity and biodegradability of hydroxyapatite. in this purpose, we firstly attempted to synthesis hydroxyapatite (ha) nanoparticles and its silica coated (si-ha) sample in collagen matrix using calcium chloride, sodium phosphate and sodium silicate. characterization of the sample was carried out using fourier transform...

The effects of a microbial inoculant (containing propionic and lactic acid bacteria) and formic acid onchemical composition, ruminal degradability of dry matter (DM) and nutrient digestibility of corn silage wereexamined. Whole-plant corn was ensiled for 60 days in plastic polyethylene bags, and three treatments werecompared, 1: control (no additive), 2: Propionibacterium acidipropionici plus L...

this study was conducted to evaluate the effects of different heating treatments (autoclaving, roasting, steam flaking and microwave irradiation) on chemical composition, anti- nutritional compounds (tannin and phenolic), in situ dry mater (dm) and crude prate in (cp) degradability. three fistulated bull in a complete randomized block design and in vitro gas production kinetics (complete random...

this study was carried out to determine the effects of lactobacillus plantarum on chemical compositionand nutritive value of whole-plant corn (wpc) ensiled at different stages of maturity. based on local routinepractice, wpc was harvested at three stages of maturity as follows: (1) two weeks before routine harvestingtime; (2), one week before routine harvesting time and (3), routine harvesting ...

Radical ring-opening copolymerization-induced self-assembly (rROPISA) was successfully applied to the synthesis of core-, surface- or surface plus core-degradable nanoparticles in heptane, leading site-specific degradability by rROPISA.

Controlled degradability in response to the local environment is one of the most effective strategies to achieve spatiotemporal release of genes from a polymeric carrier. Exploiting the differences in reduction potential between the extracellular and intracellular environment, disulfides are frequently incorporated into the backbone of polymeric drug delivery agents to ensure efficient intracel...
