This study compared the effects of adding sucrose and aspartame to the usual diet of individuals with well-controlled noninsulin-dependent diabetes mellitus (NIDDM). A double-blind, cross-over design was used with each 6-wk study period. During the sucrose period, 45 g sucrose (9% of total daily energy) was added, 10 g with each main meal and 5 g with each between-meal beverage. An equivalent s...

Accommodation and excitation in space-clamped squid axons were studied with the double sucrose gap technique, using linear current ramps, short (50 microsec) square wave pulses, and rheobasic square wave pulses as stimuli. The temperature was varied from 5 degrees to 35 degrees C. Experimental results showed a Q(10) for accommodation which was 44% higher than that for excitation. Yet calculatio...

It remains unclear whether "sucrose analgesia" is related to a pre- or postabsorptive mechanism. In a double blind cross over study sucrose reduced the pain response of preterm infants exposed to heel prick blood samples only when it was administered into the mouth. It was ineffective when administered intragastrically.

These studies have developed and tested an experimental approach to the study of membrane ionic conductance mechanisms in strips of uterine smooth muscle. The experimental and theoretical basis for applying the double sucrose-gap technique is described along with the limitations of this system. Nonpropagating membrane action potentials were produced in response to depolarizing current pulses un...

In sections of KMnO(4)-fixed, developing mouse sciatic nerves, the central gap of mesaxons in myelinating fibers is normally closed with close apposition of the outside approximately 20 A dense strata of the two approximately 75 A Schwann cell membranes. The two combined outside strata make the intraperiod line bisecting each myelin lamella. The approximately 150 A mesaxon is elaborated spirall...

The effects of caffeine (0.2-10 mM) on the electrical and mechanical activities of guinea pig taenia coli were investigated with the double sucrose-gap method. Caffeine evoked a small tension with a latency of 20-30 sec, then phasic contraction developed and finally relaxation. The initial tension development also appeared in the Na-free solution without any marked changes in the membrane poten...

the aim of this research was to improve postharvest quality and vase life of tuberose cut flowers. treatments in this experiment included: distilled water, 3% ethanol and 5% sucrose as control, thyme oil in 3 levels (50, 75 and 100 mg/l), accel in 3 level (25, 50 and 75 mg/l) and for some of flowers pulsing with 5% sucrose in first 24 hours then puting cut flowers treated with sucrose in thyme ...
