a new, local agro-industrial waste was valorized by chemical treatment and tested for its ability to remove cationic dye from aqueous solution. tendu (diospyros melanoxylon) leaves refuse, a solid waste from bidi industry which caused disposal problem, was studied as a biosorbent. raw tendu waste (tlr), along with sulfuric acid carbonized tendu waste (tlr-cm) and tendu waste treated with dilute...

Tetrazolium violet is a tetrazolium salt and has been proposed as an antitumor agent. In this study, we reported for the first time that tetrazolium violet not only inhibited human lung cancer A549 cell proliferation but also induced apoptosis and blocked cell cycle progression in the G1 phase. The results showed that tetrazolium violet significantly decreased the viability of A549 cells at 5-1...

Background: A highly efficient genetic transformation system is essential for a successful genetic manipulation of the African violet (Saintpaulia ionantha Wendl.). Objectives: Developing a particle bombardment-based genetic transformation system for the African violet. Materials and Methods: A local cultivar of the African violet from Guilan province was used for transformation experiments. Th...

The recent observation of a sharp selective bactericidal property possessed by gentian violet 1 raised the question as to which part of the gentian violet molecule was responsible for the sensitive affinity. It seemed wise to attack this problem by studying substances closely allied to gentian violet in chemical structure, 2 and the results obtained will be briefly reported in the present commu...
