In vitro antimicrobial studies of some major bioactive compounds isolated from Strychnos innocua (Delile) root bark.

Plant based therapies are very essential in modern medicine, and have long been used to cure and prevent chronic diseases in many parts of the world. Medicinal herbs have been shown to have biological properties due to the presence of active compounds. Strychnos innocua, a medicinal plant from Loganiaceae, is commonly consumed for medicinal purposes in various African countries.

In silico modelling and NMR Characterization of some steroids from Strychnos innocua (Delile) root bark as potential antifungal agents.

The root bark of Strychnos innocua has long been employed by traditional healers to treat a variety of ill health conditions including fungal infections. The objective of this study was to isolate, characterized and evaluate the antifungal potential (insilico approach) of some steroids from root bark of S. innocua.

Isolation, characterization, and docking studies of campesterol and β-sitosterol from (Delile) root bark.

Objectives: Phytosterols obtained from medicinal plants are well known for their anti-diabetic, anti-cardiovascular, anti-cancer, and anti-microbial properties. (a member of the Loganiaceae family) grows in several African nations and is frequently used for medicinal purposes.

Methods: The chromatographic separation of (root bark) ethyl acetate extract resulted in the isolation of campesterol () and β-sitosterol ().

Estimating benchmark exposure for air particulate matter using latent class models.

We performed benchmark exposure (BME) calculations for particulate matter when multiple dichotomous outcome variables are involved using latent class modeling techniques and generated separate results for both the extra risk and additional risk. The use of latent class models in this study is advantageous because it combined several outcomes into just two classes (namely, a high-risk class and a low-risk class) and compared these two classes to obtain the BME levels. This novel approach addresses a key problem in risk estimation--namely, the multiple comparisons problem, where separate regression models are fitted for each outcome variable and the reference exposure will rely on the results of the best-fitting model.

[1,4-Phenyl-enebis(methyl-ene)]bis-(tri-phenyl-phospho-nium) bis-(tetra-fluoro-borate).

The crystal structure of the title salt, C(44)H(38)P(2) (2+)2BF(4) (-), consists of discrete dications inter-laced with the BF(4) (-) counter-ions. In each cation, both phospho-nium groups lie on the same side of the plane of the central benzene ring. The tetra-fluoro-borate anions are involved in intensive thermal motion, thus some B-F bond lengths [range 1.
