Neuronal signaling, plasticity, and pathologies in CA1 hippocampal neurons are all intimately related to the redox environment and, thus tissue oxygenation. This study tests the hypothesis that hyperoxic superfusate (95% O(2)) causes a time-dependent increase in superoxide anion (*O(2)(-)) production in CA1 neurons in slices, which will decrease as oxygen concentration is decreased. Hippocampal...

Performance is critical for every listed firm, as it enhances shareholder’s value and capability to generate earnings from invested capital. Some of the firms listed on the Nairobi Securities Exchange (NSE) have been performing poorly as indicated by the rising number of firms issuing profit warnings. The competitive business environment is continuously working to drive down the rate of return ...

Fluid intelligence decreases with age, yet evidence about age declines in decision-making quality is mixed: Depending on the study, older adults make worse, equally good, or even better decisions than younger adults. We propose a potential explanation for this puzzle, namely that age differences in decision performance result from the interplay between two sets of cognitive capabilities that im...

Measurement Areas: The Universal Nonverbal Intelligence Test (UNIT) is designed to test intelligence (cognitive ability) of children and adolescents ages 5 years 0 months through 17 years 11 months who may be disadvantaged by verbal and language loaded measures. The UNIT was developed with the purpose of assessing general intelligence, two primary constructs (memory and reasoning), and two seco...
