Bitter taste perception provides animals with critical protection against ingestion of poisonous compounds. In the accompanying paper, we report the characterization of a large family of putative mammalian taste receptors (T2Rs). Here we use a heterologous expression system to show that specific T2Rs function as bitter taste receptors. A mouse T2R (mT2R-5) responds to the bitter tastant cyclohe...

Bitter taste elicits an aversive reaction, and is believed to protect against consuming poisons. Bitter molecules are detected by the Tas2r family of G-protein-coupled receptors, with a species-dependent number of subtypes. Chickens demonstrate bitter taste sensitivity despite having only three bitter taste receptors-ggTas2r1, ggTas2r2 and ggTas2r7. This minimalistic bitter taste system in chic...

Materials and methods Samples of A. pisum were collected from natural populations on vetch or white clover, preserved in acetone, and subjected to DNA extraction individually. At each locality, 20 aphids were subjected to specific PCR detection of the endosymbionts as described (S1). The aphid strain TUt, naturally infected with PAUS, was derived from a parthenogenetic female collected on white...

in order to adapt the results of previous researches on annual forage legumes in zanjan province to cold regions condition of iran, yield and quality characters of two outstanding species namely grass pea (lathyrus sativus l.) and common vetch (vicia sativa l.) were evaluated in summer fallow cultivation condition for one year in 28 locations over 11 provinces of the country. in the variance an...

Background/Introduction: Wild bitter gourd (Momordica charantia L. var. abbreviate Seringe) common vegetable in Asia, is used in traditional medicine to treat various diseases, including inflammation. Extant literature indicates that wild bitter gourds have components that activate PPARα and PPARγ. This research probed influence of adding wild bitter gourd to diets on inflammation responses in ...

The gustatory and olfactory systems are the only two systems in which stimuli act directly on the receptor. There are five taste categories which have been identified as gustatory stimuli: sweet, salty, bitter, sour, and umami (MSG). Bitter and sour are known as aversive stimuli and help mammals avoid toxic and spoiled foods. Although both are similar in that they are aversive, they work throug...

This article deals with the study of antiwear and antifriction properties of bitter rapeseed oil and sesame oil and their blends containing numerous amounts of benzoic acid at variable temperatures. The experimental results indicate that bitter rapeseed oil exhibits good antiwear and antifriction properties as compared to sesame oil under the same experimental conditions. The addition of benzoi...

Soil carbon (C) sequestration in tilled and nontilled areas can be influenced by crop management practices due to differences in plant C inputs and their rate of mineralization. We examined the influence of four cover crops {legume [hairy vetch (Vicia villosa Roth)], nonlegume [rye (Secale cereale L.)], biculture of legume and nonlegume (vetch and rye), and no cover crops (or winter weeds)} and...

The purpose of this study was to evaluate the antioxidant and anticholinesterase activities of yellow and white bitter yams from South Western Nigeria using methanolic extraction and simulated gastrointestinal digestion models. The phenolic compounds in the bitter yam varieties were evaluated by high performance liquid chromatography with a diode array detector (HPLC-DAD). The total phenolic co...
