Four different plant secondary metabolites were screened for their effect on rumen biohydrogenation of forage long-chain fatty acids, using dual-flow continuous culture fermenters. Treatments were as follows: control (no additive), positive control (12 mg/L of monensin), and plant extracts (500 and 1,000 mg/L of triterpene saponin; 250 and 500 mg/L of quercetin; 250 mg/L of eugenol; 500 mg/L of...
Conventional N-glycoproteome analysis usually applies C18 reversed-phase (RP) adsorbent for sample purification, which will lead to unavoidable sample loss due to the high hydrophilicity of N-glycopeptides. In this study, a porous graphitized carbon (PGC) absorbent was combined with a C18 adsorbent for N-glycopeptide purification in comprehensive N-glycoproteome analysis based on the hydrophobi...
A Ca2+ indicator has been synthesized and characterized which can be used to monitor rapid changes in the free Ca2+ concentration ([Ca2+]) immediately adjacent to cell membranes. This indicator, referred to as C18-Fura-2, consists of a Fura-2 molecule conjugated to a lipophilic alkyl chain which will insert into cell membranes. When associated with cell membranes in low concentrations, C18-Fura...
Twenty-seven lambs were used to investigate the effects of the inclusion of 4% hydrogenated palm oil (HPO) or sunflower oil (SFO) in the concentrate on animal performance, carcass and meat quality and fat characteristics and fatty acid composition. Animals (16.2±0.27kg initial weight) were fed concentrate (Control, HPO or SFO) and barley straw ad libitum and slaughtered at 25kg. SFO lambs tende...
Essentially chlorophyll-free mitochondria from photosynthetic (leaf) and non-photosynthetic tissue (petiole) were isolated from spinach (Spinacia oleracea). Leaf mitochondria were found to contain more phosphatidylcholine than phosphatidylethanolamine compared with petiole mitochondria. Galactolipids were found in small and equal amounts (5 mol of galactolipids/100 mol of galactolipids and phos...
The strong link between saturated fat intake and increasing rates of coronary heart disease have provided the impetus for the dairy industry to provide milk with an increased proportion of polyunsaturated fatty acids. This can be achieved with the inclusion of protected lipid supplements in the diet of dairy cow. The protection from ruminal degradation is achieved by encapsulation of the lipid ...
Here, we studied the underlying mechanism of aldosterone (Aldo)-induced vascular endothelial cell damages by focusing on ceramide. We confirmed that Aldo (at nmol/L) inhibited human umbilical vein endothelial cells (HUVEC) survival, and induced considerable cell apoptosis. We propose that ceramide (mainly C18) production might be responsible for Aldo-mediated damages in HUVECs. Sphingosine-1-ph...
The aim of this study was to provide information on the fatty acid profile of different adipose depots – subcutaneous (upper and inner backfat layers) and intramuscular (m. Longissimus dorsi) in East Balkan pigs. The animals were reared in free-range conditions and slaughtered at an average live weight of 107±1.65kg. The results of the study showed that the various adipose tissues in pigs have ...
Rat brain increases in weight after birth in three stages: (I) rapidly for the first 2 weeks, (II) at a lower rate from 2 to 5 weeks, and (III) at a still lower rate from 5 weeks to 5 months. During the succeeding period, designated IV, it maintains constant weight up to 1 year of age. Brain ganglioside content increased linearly during I and II, more slowly during III, and diminished during IV...
