Consumption of 1% sucrose solution supplemented with 0.2% vanillin was studied in two experimental contexts in male mice living under chronic social stress induced by daily experience of defeats in agonistic interactions and leading to development of depression. In the first experiment, vanillin sucrose solution was made available as an option along with water during 10 days for mice living in ...

The purpose of this study was to investigate the relationship among frequency of sucrose exposure, mutans streptococci levels and dental caries. Adult volunteers took part in this crossover study performed in 4 phases of 28 days each. The volunteers wore intra-oral palatal appliances containing blocks of human dental enamel and dripped 20% sucrose solution onto the dental blocks from 0 to 8 tim...

Laboratory mice drink little sucrose solution on initial exposure, but later develop a strong preference for sucrose over water that plateaus after a few days. Both the initial neophobia and later plateau of sucrose intake may involve central oxytocin (OT) signaling pathways. If so, then mice that lack the gene for OT [OT knockout (KO)] should exhibit enhanced initial and sustained sucrose inta...

Introduction Quantitative analysis shows that sucrose is the major organic constituent of phloem exudates in mlost plants (6, 8). When leaves are allowed to photosynthesize in C140, for short periodls nmost of the translocatedl radioactiv,ity is generally found in sucrose (6, 8). With respect to the nature of the transit compound in these plants there are 3 possible hypotheses whiclh are consis...

Abstract This study was carried out in the laboratory of Shangqiu Institute Technology, Henan to investigate effect a different combination inorganic salt on quality and physiological characteristics cut flowers (CFs) Perpetual Carnation. Furthermore, find best preservation solution that can enhance ornamental value CFs Carnation prolong its vase life. Sucrose, 8-hydroxyquinoline, paclobutrazol...

Objective: To determine the level of biofilm formation S. mutans after being exposed to 5% sucrose, 8% lactose, or 1% xylitol. Material and Methods: This research was a laboratory-based experimental study with post-test only control group design. grown in test tubes containing tryptose soy broth (TSB) medium supplemented glucose. They were incubated at 37° C for 24 hours grow biofilms. The cult...

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...

Vriesea incurvata is a native bromeliad from Brazilian Atlantic Rainforest and commercialized as an ornamental pot plant. The morphological characteristics of its floral scape may also indicate it new product to use cut flower. However, postharvest behavior was unknown. This study conducted determine vase life by applying distilled water (control) solutions containing sucrose (50 g L-1), salicy...
