    Impact of inflation on stock market performance
    (October University of Modern Sciences and Arts, 2019) Maged, Rami; Abbas, Youssef; Mohsen, Aya; Essam, Mostafa; Hassan, Omar
    In the literature, it is known that there is a relationship between inflation rate and stock market performance. most studies proves that there is a negative relationship between the inflation and stock market performance, even with different methodologies the outcome proves the negative relationship, According to Upadhyay (2017) they used the consumer price index and the national stock exchange indicator and the result are sufficient to ensure that changes in stock prices over the period of selected time are not due to fluctuations in the CPI, but due to the changes in stock prices due to certain other factors available on the market. Stock market performance is measured with many indicators and one of them EGX30, and trade volume. This research aims to investigate whether if the inflation rate has a significant impact on stock market performance measured by EGX30, and trade volume. The data will be analyzed using statistical program called SPSS, the analysis will be done through descriptive analysis, correlation and multivariate regression analysis (MANOVA). The results were that there is a significant impact for the inflation rate on stock market performance.

    Neuroprotective effects of zafirlukast, piracetam and their combination on L‐Methionine‐induced vascular dementia in rats
    (SFPT, 2019-12) Hassan, Omar; Bahnasawy, Nada H; Elnoby, Ahmed S; Fayez, Ahmed M
    Vascular dementia is considered a vascular cognitive impairment disease caused by neuronal degeneration in the brain. Several studies have supported the hypothesis that oxidative stress and endothelial dysfunction are the main pathogenic factors in vascular dementia. This current study aims to determine the possible neuroprotective effects of zafirlukast, piracetam and the combination of piracetam and zafirlukast on L‐methionine‐induced vascular dementia in rats. Male Wistar albino rats were divided into five groups. Group I was the normal control, and group II received L‐methionine (1700 mg/kg, P.O.) for 32 days. The remaining groups received zafirlukast (20 mg/kg, P.O.), piracetam (600 mg/kg, P.O.) or their combination (zafirlukast 20 mg/kg + piracetam 600 mg/kg, P.O.) for 32 days after L‐methionine administration. Afterwards, the cognitive and memory performances of the rats were investigated using the novel object recognition (NOR) test; rats were then sacrificed for histopathological and biochemical analyses. L‐methionine‐induced vascular dementia altered rats’ behaviours and the brain contents of different neurotransmitters and acetylcholinesterase activity while increasing levels of oxidative stress and causing notable histopathological alterations in brain tissues. The treatment of vascular dementia with zafirlukast and the combination improved neurochemical, behavioural and histological alterations to a comparable level to those of piracetam. Thus, zafirlukast, piracetam and the combination of both drugs can be considered as potential therapeutic strategies for the treatment of vascular dementia induced by L‐methionine. To the best of our knowledge, this study is the first to explore the neuroprotective effects of zafirlukast and piracetam on L‐methionine‐induced vascular dementia
