Roux-en-Y gastric bypass (RYGB) surgery has been shown to decrease consummatory responsiveness of rats to high sucrose concentrations, and genetic deletion of glucagon-like peptide-1 receptors (GLP-1R) has been shown to decrease consummatory responsiveness of mice to low-sucrose concentrations. Here we assessed the effects of RYGB and pharmacological GLP-1R modulation on sucrose licking by chow...

To test for retrospective effects of sucrose ingestion in the anticipatory contrast procedure, 4 experiments examined intake of an initial 0.15% saccharin solution as a function of the unsignaled interspersing of days in which the 2nd solution was 32% sucrose or 0.15% saccharin. In Experiment 1, rats that received alternating saccharin-saccharin days and saccharin-sucrose days drank less saccha...

The growth constant and Y (sucrose) (grams of cells per mole of sucrose) for NH(3)-grown cultures of Clostridium pasteurianum were 1.7 times those of N(2)-grown cultures, whereas the rate of sucrose utilized per gram of cells per hour was similar for both conditions. The Y (sucrose) of chemostat cultures grown on limiting NH(3) under argon at generation times equal to those of N(2)-fixing cultu...

1. Molar growth-yield coefficients of Zymomonas mobilis for glucose, fructose, glucose plus fructose, and sucrose are reported. Yield coefficients for sucrose are appreciably lower than those for the equivalent concentrations of glucose plus fructose. 2. Only 2.6% of [U-(14)C]glucose supplied in the growth medium is incorporated into cell substance by Z. mobilis utilizing glucose as the energy ...

Focus has centered on C-partitioning in stems of sugarcane (Saccharum sp.) due to their high-sucrose accumulation features, relevance to other grasses, and rising economic value. Here we review how sugarcane balances between sucrose storage, respiration, and cell wall biosynthesis. The specific topics involve (1) accumulation of exceptionally high sucrose levels (up to over 500 mM), (2) a poten...

effect of different co2 concentrations on sucrose metabolizing enzymes and on carbohydrate metabolism was studied for eight blackgram (vigna mungo l. hepper) genotypes grown in open top chambers under ambient (380 µmol mol-1) vs. elevated co2 (550 and 700 µmol mol-1) levels. the higher acid invertase activity over neutral invertase indicated the major role of acid invertase in sucrose breakdown...

This study evaluated the use of splice grafting as a propagation strategy for watermelon. In experiment 1, treatments consisted sucrose, antitranspirant A, B, auxin (indole-3-butyric acid (IBA)) at two concentrations (10 and 20 mg·L−1), plus water control. The survival (%) splice-grafted watermelon plants differed due to number days after treatment (p < 0.0001, both). At 21 grafting, treated...

Light emitting diodes (LEDs) are potential light sources for in vitro plant cultures. Here, axillary blackberry shoots were grown MS medium with indole-3-butyric acid (1 mg L−1), naphthalene acetic (0.5 and sucrose supplementation (0–60 g L−1) the cultures incubated under four treatments: three LED treatments (blue + red (2:1 spectral ratio), blue (1:2), cool warm white (1:1)) a standard flores...

Eggs of the sea urchin Arbacia punctulata were collected by the electroshock method (1), washed in artificial seawater, and sedimented by centrifugation at 500 g for 3 min . Embryos were obtained by fertilizing eggs in artificial seawater with a drop of fresh dilute sperm suspension . Only those cultures in which fertilization was 95-1007 effective were used for the isolation of nuclei. The sed...

The aim of this study was to determine the effects of different plant growth regulators, NAA (0 mg/l, 50 mg/l and 100 mg/l) and GA3 (0 mg/l, 50 mg/l and 100 mg/l), with various boron concentrations (0 mg/l, 50 mg/l and 100 mg/l) on pollen germination of ‘Şaba’, ‘Rabie’ and ‘Padre’ almond cultivars in 10% sucrose and 1% agar medium at 24°C in dark conditions. The results showed that different tr...
