Background: Liver cancer is the second outstanding reason for cancer-related death global and thus a main public health challenge. Plant-based drugs are regarded as promising therapies. Basil and Dracocephalum kotschyi extracts have shown therapeutic impacts on various cancers. Therefore, we assessed the effects of the extract of Basil and Dracocephalum kotschyi on cell proliferation and BCL2 e...

The study aimed to determine the effects of Salvadora persica L. sticks on oral bacteria and odor in comparison to traditional mouth disinfection with mouth rinses. Thirty-five healthy fasting volunteers took part in a crossover clinical trial involving the application of Listerine Cool Mint mouth rinse by the traditional panoral rinsing method or a site-specific method targeting the subgingiva...

The alkaloid composition of the aerial parts of two taxa of Teline maderensis was studied by capillary GLC and GLC-MS. N-Methylcytisine was the major alkaloid found in both plants. Contents of cytisine and lupanine were higher in T. maderensis var. paivae while anagyrine content was more pronounced in T. maderensis var. maderensis. The alkaloids dehydrocytisine, N-acetylcytisine and epibaptifol...

This paper develops methods for Bayesian VAR forecasting when the researcher is uncertain about which variables enter the VAR and the dimension of the VAR may be changing over time. It considers the case where there are N variables which might potentially enter a VAR and the researcher is interested in forecasting N∗ of them. Thus, the researcher is faced with 2N−N ∗ potential VARs. If N is lar...

In this article we investigate the theoretical behaviour of finite lag VAR(n) models fitted to time series that in truth come from an infinite order VAR(∞) data generating mechanism. We show that overall error can be broken down into two basic components, an estimation error that stems from the difference between the parameter estimates and their population ensemble VAR(n) counterparts, and an ...

Plants produce a number of antimicrobial substances and the roots of the shrub Salvadora persica have been demonstrated to possess antimicrobial activity. Sticks from the roots of S. persica, Miswak sticks, have been used for centuries as a traditional method of cleaning teeth. Diverging reports on the chemical nature and antimicrobial repertoire of the chewing sticks from S. persica led us to ...
