Cytotoxic Effects of Some Species against Breast Cancer Cell Lines and Their Associated Phytochemical Properties.

is one of the largest genera of the Lamiaceae family. species are commonly employed in traditional medicine for a variety of ailments, as well as food additives. In addition, they also come to the fore with their rich phytochemical content.

Variability in the analysis of a single neuroimaging dataset by many teams.

Data analysis workflows in many scientific domains have become increasingly complex and flexible. Here we assess the effect of this flexibility on the results of functional magnetic resonance imaging by asking 70 independent teams to analyse the same dataset, testing the same 9 ex-ante hypotheses. The flexibility of analytical approaches is exemplified by the fact that no two teams chose identical workflows to analyse the data.

Considerations of power and sample size in rehabilitation research.

With the current emphasis on power and reproducibility, pressures are rising to increase sample sizes in rehabilitation research in order to reflect more accurate effect estimation and generalizable results. The conventional way of increasing power by enrolling more participants is less feasible in some fields of research. In particular, rehabilitation research faces considerable challenges in achieving this goal.

Bioassay-guided isolation of cytotoxic compounds from Chrysophthalmum montanum (DC.) Boiss.

Bioassay-guided isolation of the 80% methanol extract of the aerial parts of Chrysophthalmum montanum (DC.) Boiss. (Asteraceae) led to the isolation of four known guaianolide-type sesquiterpene lactones, 6α-acetoxy-4α-hydroxy-1βH-guaia-9.

Phytotoxicity, Toxicity on Brine Shrimp and Insecticidal Effect of Aytac & Anderb. Growing in Turkey.

Objectives: The aim of this study was to investigate the probable toxicity on brine shrimp, phytotoxicity, and insecticidal activity of Aytac & Anderb.

Materials And Methods: The MeOH (80%) extract obtained from the whole plant of was fractionated through subsequent solvent extractions in increasing polarity with -hexane, chloroform, and -butanol. The MeOH (80%) extract and all fractions of were evaluated for their biologic activities using screening bioassays such as brine shrimp lethality test and phytotoxicity against , as well as insecticidal activity against and .
