One of the most effective ways to propagate Lilium is by using tissue culture techniques, preferably through bulblet production. In addition to the surviving percentage of Lilium bulbs after transplantation, the small size of in vitro bulblets compared to commercial bulbs and bulblets‟ dormancy are the most important constraints to commercializing Lilium micropropagation. Different concentratio...

Daily intermittent access to sugar solutions results in intense bouts of sugar intake (i.e. bingeing) in rats. Bingeing on sucrose, a disaccharide of glucose and fructose, has been associated with a "primed" mesolimbic dopamine (DA) pathway. Recent studies suggest glucose and fructose engage brain reward and energy-sensing mechanisms in opposing ways and may drive sucrose intake through unique ...

We have recently shown the occurrence of endocytic sucrose uptake in heterotrophic cells. Whether this mechanism is involved in the sucrose-starch conversion process was investigated by comparing the rates of starch accumulation in sycamore cells cultured in the presence or absence of the endocytic inhibitors wortmannin and 2-(4-morpholynyl-)-8-phenyl-4H-1 benzopyran-4-1 (LY294002). These analy...

Fermentative hydrogen production from a synthetic wastewater containing 10 g/L of sucrose was studied in two upflow reactors at 26 degrees C for 400 days. One reactor was filled with packing rings (RP) and the other was packing free (RF). The effect of hydraulic retention time (HRT) from 2 h to 24 h was investigated. Results showed that, under steady state, the hydrogen production rate signific...

Three soluble isoforms of invertase (8-fructofuranosidase; EC 3.2.1.26) were purified from 7-d-old primary leaves of barley (Hordeum vurgare 1.). lnvertase I, a monomeric protein of 64 kD, was purified to apparent homogeneity as shown by sodium dodecylsulfate-polyacrylamide gel electrophoresis. lnvertases IIA and IIB, multimeric proteins with molecular masses of 116 and 155 kD, were purified 78...

by gest on N ovem er 8, 2016 D ow nladed fom Recently, differing views as to the genesis of monophasic action potential (MAP) recordings have surfaced [1–3]. Kondo et al. [1,3] claim that MAP recordings come about because core conductor theory dictates that the extracellular potential is a scaled version of the transmembrane voltage and that the contact electrode acts as a stationary ground. Fr...

Cytosol from rat and mouse adrenal glands has been shown to contain a macromolecule which binds estradiol, but not corticosterone or testosterone. The receptor. estrogen complex has a sedimentation coefficient of 8 S when centrifuged on low salt sucrose gradients. Centrifugation on 0.4 M KC1 gradients results in an 8 S + 4 S transformation. The estrogen-binding entity is, at least partially, a ...

in order to examine the effects of essential oils and silver nanoparticles as anantimicrobial preservative in the solutions of alstroemeri cv. sukari cut flowers, anexperiment was conducted with 11 treatments and 3 replications in a completelyrandomized design. in this study, we used essences of carvacrol, thymol and zataria oilwithconcentrations of 50 and 100 mg l-1 and silver nanoparticles wi...
