a thin layer solar drying method was compared with a traditional method (sun drying) of paddy drying, with their effects on quality characteristics of two varieties of iranian rice (kamphiroozi and sazandegi) studied. solar drying process was conducted in a passive, mixed mode type solar dryer at about 50ºc for 90 minutes. in sun drying method this process took 8-10 hours at a mean temperature ...

The production of a new class microfluidic devices built from thermoplastic materials has recently aroused interest in high-volume and cost-effective fabrication sensing devices. During device formation, the bonding two slides, one containing microchannels another used as non-modified capping layer, is generally performed at high temperature, pressure, and/or employing organic solvents. Such pr...

Freely occurring alpha-l-aspartyl-l-histidine, beta-alanyl-l-histidine (carnosine), alpha-l-aspartyl-alpha-l-lysine, l-asparaginyl-alpha-l-lysine, alpha-l-glutamyl-alpha-l-lysine, l-isoleucyl-alpha-l-lysine, l-seryl-alpha-l-lysine, l-valyl-alpha-l-lysine and glycyl-alpha-l-lysyl-alpha-l-lysine were identified in young larvae (second and third instars) of the blowfly (Phormia regina).

Lysine propionylation and butyrylation are protein modifications that were recently identified in histones. The molecular components involved in the two protein modification pathways are unknown, hindering further functional studies. Here we report identification of the first three in vivo non-histone protein substrates of lysine propionylation in eukaryotic cells: p53, p300, and CREB-binding p...

lysine metabolism has been measured in rats fed a diet low in trimethyl-lysine and carnitine (Davis & Hoppel, 1983, 1986). Under these steady-state conditions, the total body trimethyl-lysine content is similar to the total body carnitine content. The tissue distribution of peptide-linked and free trimethyl-lysine shows that approximately 68% of the total trimethyl-lysine is present in skeletal...

Two experiments were conducted to compare the nutritional adequacy of a genetically improved high-lysine, high-oil corn (HLHOC; .408% lysine, 6.21% fat, as-fed basis) and a high-oil corn (HOC; .289% lysine, 5.97% fat, as-fed basis) for young growing pigs. Experiment 1 used four non-littermate barrows (initially 20.0 kg BW) fitted with ileal T-cannulas in a crossover-designed digestion study. Th...

Lysine is frequently a first- or second-limiting amino acid in poultry diets. Improving the efficiency of lysine use for protein synthesis would effectively lower the lysine requirement and decrease feed costs. Understanding how lysine is degraded and how the degradation is regulated would identify potential molecular targets for interventions to decrease lysine degradation. To better understan...

The accumulation of free lysine in tobacco seed triggers the stimulation of lysine-ketoglutarate reductase, an enzyme that acts in lysine catabolism. The mechanism of lysine-ketoglutarate reductase stimulation was studied in two different systems: (1) developing seeds of wild-type plants in which the low basal lysine-ketoglutarate reductase activity can be stimulated by the exogenous addition o...
