atp-sensitive potassium (katp) channel openers have a relaxation effect due to the lower cellular membrane potential and inhibit calcium influx. there has been considerable interest in exploring katp channel openers in the treatment of various diseases such as cardiovascular, cerebrovascular, and urinary system disease and premature labor. the purpose of this study was to synthesize 3,3,6,6-tet...

This study was conducted to determine the effects of different irrigation water treatments and silicon doses on leaf SPAD meter readings, chlorophyll content carotenoid contents tomato plants. Tybiff Aq seedling were grown in 3-liter pots filled with 1100 g 1:1 peat-perlite mixture for 70 days. Four type waters prepared use sea tap water. Irrigation included I) Full water, II) ½ + III) ¼ ¾ IV) ...

Parathyroid cells have unusual responses to an increase in the external calcium concentration--a reduction in secretion and a depolarization. In an attempt to explain this behavior, we have studied voltage-clamped inside-out patches from bovine parathyroid cells. We found a potassium-selective channel that requires internal calcium to open and has a 175-pS conductance. This channel differs from...

This study was conducted to determine the effects of different vermicompost doses on plant growth, quality properties and element contents in curly lettuce (Lactuca sativa L. var. crispa). The research carried out pots under plastic greenhouse conditions Karabük province. In study, 6 applications as 4 (V), chemical fertilizer (CF) control were examined. follows: 1) Control (100% soil), 2) V1 (9...

Tigernut, or Cyperus esculentus L, is a tuber that grows and frequently consumed in West Africa. Tigernut highly nutritive with high starch, glucose proteins contents. It's minerals (including phosphorus potassium), as well vitamins C, D, B1, which all assist to improve antioxidant activity. It can be raw dried combined roasted peanuts. The minerals, phytochemical contents of ...

The seeds of Guibourtia coleosperma serve as potential source nutritious food for rural communities in northern Botswana though underutilized. objective this study was to determine the proximate and mineral composition G. collected from Botswana. Seed samples were Shakawe Kasane areas contents seed determined following standard procedures. data analyzed using T-test. Seeds had average moisture ...

Experiments were performed to determine the quantitative relation existing between action potential and resting potential of the lobster giant axon. Resting potential changes were induced by either increasing the external potassium concentration or by reducing the external calcium concentration. For either treatment the action potential amplitude is proportional to the logarithm of the resting ...
