diabetic retinopathy is the leading cause of blindness in the world. strict control of blood sugar, blood pressure, laser therapy, pharmacotherapy and vitrectomy are of among common diabetic retinopathy treatments. further studies to investigate the effect of protein kinase c inhibitors, angiotensin converting enzyme inhibitors, growth hormone and other proposed treatments for diabetic retinopa...

Commercial juices of sweet pomegranates and fresh juices of sour-sweet pomegranates were analysed for organic acids, sugars, antioxidant activity, volatile composition, sensory profile and consumer liking. Organic acids and sugars were analysed by HPLC, while volatiles were extracted using hydrodistillation and analysed by GC-MS and GC-FID. Malic acid was predominant in sweet juices while citri...

BACKGROUND/OBJECTIVES The aim of this study was to investigate the perception of sugar reduction, nutrition education, and frequency of snacking in children according to the self-perceived dietary preferences for sweet taste by mothers in Busan. SUBJECTS/METHODS A total of 277 mothers were surveyed, and their perceptions of sugar reduction and the frequency of snacking in children were assess...

In diabetes, the main part of treatment is left on the patient himself, so their knowledge in different aspects of treatinent, specially the nutritional management, is of great importance. Our study with the aim of surveying the nutritional knowledge of diabetic patients was conducted in Semnan, in 1997. In this descriptive study, the initial data were gathered through questionnaire and face to...

Pairing an odor and taste can change ratings of the odor's perceptual and hedonic characteristics. Behavioral indices of such changes are lacking and here we measured sniffing to assess learned changes in odor liking due to pairing with sweet and bitter tastes. Participants were divided on their liking for sweetness, as well as dietary disinhibition (Three-Factor Eating Questionnaire-Disinhibit...

Although the five basic taste qualities-sweet, sour, bitter, salty and umami-can be recognized by the respective gustatory system, interactions between these taste qualities are often experienced when food is consumed. Specifically, the umami taste has been investigated in terms of whether it enhances or reduces the other taste modalities. These studies, however, are based on individual percept...

Sweet tasting foods have been found to have an analgesic effect. Therefore people might consume more sweet-tasting food when they feel pain. In Study 1, participants were randomly assigned to a pain or non-pain condition and their consumption of cheesecake was measured. Participants ate more cheesecake (a sweet-tasting food) following a painful experience than a non-painful one. In Study 2, par...

Sweet taste cells play critical roles in food selection and feeding behaviors. Drosophila sweet neurons express eight gustatory receptors (Grs) belonging to a highly conserved clade in insects. Despite ongoing efforts, little is known about the fundamental principles that underlie how sweet tastants are detected by these receptors. Here, we provide a systematic functional analysis of Drosophila...

Nematode population densities and yield of sweet corn and sweet potato as affected by the nematicide fenamiphos, in a sweet corn-sweet potato-vetch cropping system, were determined in a 5-year test (1981-85). Sweet potato was the best host of Meloidogyne incognita of these three crops. Fenamiphos 15G (6.7 kg a.i./ha) incorporated broadcast in the top 15 cm of the soil layer before planting of e...

The sweet taste receptor is expressed in taste cells located in taste buds of the tongue. This receptor senses sweet substances in the oral cavity, activates taste cells, and transmits the taste signals to adjacent neurons. The sweet taste receptor is a heterodimer of two G protein-coupled receptors, T1R2 and T1R3. Recent studies have shown that this receptor is also expressed in the extragusta...
