Regioselective syntheses of 2-oxopyridine carbonitrile derivatives and evaluation for antihyperglycemic and antioxidant potential
(Elsevier, 2023)A library of 2-oxopyridine carbonitriles 1-34 was synthesized by regioselective nucleophilic substitution reactions. In the first step, a one-pot multicomponent reaction yield pyridone intermediates. The resulting pyridone ... -
Regularized trace formula for higher order differential operators with unbounded coefficients
(Texas State Univ, 2016)In this work we obtain the regularized trace formula for an even-order differential operator with unbounded operator coefficient. -
The relations between antioxidant enzymes and chlorophyll fluorescence parameters in common bean cultivars differing in sensitivity to drought stress
(Springer, 2011)Effects of the antioxidant system and chlorophyll fluorescence on drought tolerance of four common bean (Phaseolus vulgaris L.) cultivars were studied. The cultivars were positioned in the order of a decrease in their ... -
The relationship between leaf rolling and ascorbate-glutathione cycle enzymes in apoplastic and symplastic areas of Ctenanthe setosa subjected to drought stress
(2009)The ascorbate-glutathione (ASC-GSH) cycle has an important role in defensive processes against oxidative damage generated by drought stress. In this study, the changes that take place in apoplastic and symplastic ASC-GSH ... -
The relationships between plant zonation and edaphic factors in halophytic vegetation around Lake Tuz, Central Anatolia, Turkey
(Springer, 2012)The zonation pattern of halophytic species around Lake Tuz (Central Anatolia-Turkey) was determined according to the chemical properties of soil samples via seasonal evaluation. the most dominant ions at soils around Lake ... -
Relationships between vegetation zonation and edaphic factors in a salt-marsh community (Black Sea coast)
(2009)The effects of pH, electrical conductivity (EC), soluble cations (Na +, K +, Ca 2+, Mg 2+), and soluble anions (HCO 3 -, Cl -, SO 4 2-) on vegetation zonation in a salt-marsh community (Black Sea coast) were investigated ... -
