Background: Development of safe radioprotector is a challenging task. In this study radioprotective effect of sucrose has been demonstrated in calf thymus DNA (CtDNA). Sucrose is a free radical scavenger and also acts as osmolyte and therefore can influence the water activity around DNA and effects of radiation on DNA. Hoechst 33258 was used to probe the possible alteration in physicochemical p...

introduction: mouse embryos can successfully be frozen with sucrose and propandiol. however, different developmental stages of mammalian embryos have shown to have various capacities to undergo freeze-thawing procedure. in the present study, the ability of 1,2,4 and 8-ell mouse embryo to tolerate the freeze-thawing procedure was investigated and the effect of this procedure on the further in vi...

BACKGROUND The aim of the study was to determine the influence of DRD2 gene polymorphisms in exon 8 G/A (rs 6276) in the promoter region -141 C Ins/Del (rs1799732) and the influence of ANKK-1 gene Taq-1A polymorphism (rs 1800497) on the preference of increasing sucrose concentrations in men with alcohol dependence. SUBJECTS AND METHODS 63 male patients with alcohol dependence were genotyped f...

The activity of sucrose phosphate synthase, sucrose synthase, and acid invertase was monitored in 1- to 2-month-old sugar beet (Beta vulgaris L.) leaves. Sugar beet leaves achieve full laminar length in 13 days. Therefore, leaves were harvested at 2-day intervals for 15 days. Sucrose phosphate synthase activity was not detectable for 6 days in the dark-grown leaves. Once activity was measurable...

OBJECTIVES To assess and compare the analgesic effects of orally administered glucose and sucrose and pacifiers. To determine the synergistic analgesic effect of sucrose and pacifiers. DESIGN Randomised prospective study with validated behavioural acute pain rating scale. SETTING Maternity ward. PARTICIPANTS 150 term newborns undergoing venepuncture randomly assigned to one of six treatme...

Three experiments compared the potency of the type A cholecystokinin (CCKA)-receptor antagonist devazepide for increasing intake of 30% sucrose when injected into the superior pancreaticoduodenal (SPD) artery (SPD group) or jugular vein (IV group). In experiment 1, 15 min of sucrose intake in adult, male Sprague-Dawley rats after 6 h of food deprivation was increased by devazepide (20 μg/kg) ad...

Background: Nowadays, cryoprotectant-free vitrification of human sperm in large or small volumes facilitated storage and use of human sperm for long time. However, this procedure was not successful in farm animals. The main finding in the studies is higher sensitivity of these kinds of sperm to sucrose osmolarities. Preliminary studies showed a reversible effect of sucrose on goat epididymal sp...

Sucrose ester can be synthesized enzymatically using fatty acid or ester. The research has been carried out methyl as a substrate in the synthesis of sucrose enzymatically. Initially, was from crude palm kernel oil (off grade) through two-step reaction and obtained an content 96.5927%. Furthermore, esterification between Candida antarctica biocatalyst. This study aimed to determine effect time ...

In this study, the effects of concentration and application time of ethephon on growth parameters; stem height, stem diameter, biomass, carbohydrate content; sucrose content, invert sugar, brix value, and juice volume of two sweet sorghum cultivars were determined. Three ethephon application time (8 leaves, booting, and flowering) and five ethephon concentrations (0, 200, 400, 600, and 800 ppm)...
