We use small angle neutron scattering (SANS), with an original analysis method, to obtain both the characteristic sizes and the inner composition of lysozyme-pectin complexes depending on the charge density. Lysozyme is a globular protein and pectin a natural anionic semiflexible polysaccharide with a degree of methylation (DM) 0, 43, and 74. For our experimental conditions (buffer ionic streng...

The effect of a group of model lysosomotropic compounds on the process of Ca2+ ion desorption from lecithin liposome membranes was studied. The compounds studied were: hydrochlorides of fatty acids 2-dimethylaminoethyl esters (DM-n) for n = 9, 11, 13 and 15 carbon atoms in the fatty acid alkyl chain and methochloride of 2-dimethylaminoethyl laurate (DMS-11). It was found that all the compounds ...

Six Red Maasai sheep were used to investigate the effects of urea treatment and cotton seed cake supplementation of maize stover on intake, digestibility and rumen fermentation parameters. The basal feeds were Rhodes grass (Chloris gayana) hay (H), untreated maize (Zea mays) stover (US) and treated maize stover (TS), each of which was supplemented with 100 g of cotton seed cake (CSC) to make H+...

The aim of the present study was to investigate the effects of hydrogen sulfide (H2S) on the activity and expression of inducible nitric oxide synthase (iNOS) in the myocardial tissue of type 1 diabetic rats. Rats were divided randomly into four groups: Normal control (NC), diabetes mellitus (DM), DM+DL‑Proparglygylcine (DM+PAG) and DM+sodium hydrosulfide (DM+NaHS) groups. Type 1 diabetes was i...

In the present study we have developed the agar-fill method for the measurement of gastrointestinal-tract capacity (GTC) to replace the in vitro water-fill method. This would estimate GTC without using complex equipment and techniques, and can be applied to the measurement of GTC for small laboratory animals. We attempted to confirm the efficiency of the agar-fill method by investigating the re...

this experiment was conducted to determine the effects of propionic acid, formic acid, molasses and molasses plus urea on chemical composition, microbial population, ruminal degradability of dry matter (dm) and crude protein (cp), and aerobic stability of corn silage. prior to ensiling, whole crop corn was chapped and treated with water (control), propionic acid (1%), formic acid (0.8%), molass...

With high dry matter yields of high quality forage, high soluble carbohydrate levels and a suitability for harvest by cutting and removing, the forage legume sulla (Hedysarum coronarium) has the potential to be an important silage crop in New Zealand. In three experiments the ensiling potential of sulla was compared with conventional pasture using a mini-silo system which allows for rapid evalu...

thirty five growing male goats (6.98±0.86 kg bw) were divided into five equal groups with seven animals in each group. the five dietary treatments were consisted of varying proportions of moringa foliage (moringa oleifera) and napier grass (pennisetum purpurium); t1 (100% moringa foliage); t2 (75% moringa foliage+25% napier grass); t3 (50% moringa foliage+50% napier grass); t4 (25% moringa foli...
