Hyperkalemia-induced impairment of EDHF function is ameliorated by addition of KATP channel openers such as nicorandil, aprikalim, and KRN4884 in cardioplegic solutions [ 15, 40, 112].
The data on cell cycle analysis clearly revealed the role of STZ as an apoptotic agent, and the effect seen with the plant extracts revealed the role of plants as anti-apoptotic agents suggesting that the observed growth-inhibitory effect of STZ in RIN cells could be ameliorated by addition of these plants.
The effect on intake and average daily gain was ameliorated by the addition of PEG, which complexes with phenolic compounds.
This observation supports our hypothesis that induction of Notch pathway by radiation is one mechanism of resistance to radiation and can be ameliorated by the addition of GSI.
Furthermore, the inhibitor treatment increased anxiety index of rats in the open field and this was ameliorated by the addition of 17α-estradiol.
This effect was ameliorated by the addition of NM-105, stimulating reproduction by 17% at 200 mg/kg and by 27% at 500 mg/kg.
Pink1-deficient brain mitochondria displayed a significant reduction in Ca2+ buffering capacity, which could be ameliorated by the addition of the PTP inhibitor cyclosporine A (CsA) (Fig. 4A).
Furthermore, the observed scattered insulin expression pattern in Wnt-5 morphant embryos was ameliorated by the addition of wnt-5* mRNA that encodes an altered wnt5 open reading frame engineered with degenerate nucleotides in the region around the translation start site to avoid targeting by the wnt-5 MO (see Methods).
The negative effects of HFD can be ameliorated by the simultaneous addition of dietary α-lipoic acid and garlic, the intake of which decreased liver lipid peroxidation intensity, free radical damage of DNA, and the development of nonalcoholic steatohepatitis.
In a model of autophagy deficiency occurring within the pancreatic β cell, we further demonstrate that the overall physiological impairment in glucose tolerance and insulin secretion can be significantly ameliorated by the simple addition of an antioxidant.
Such limitations have been ameliorated by the development of large depositories of electronic medical data.
