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...

Aged distilled beverages (cognac and brandy) contain phenolic antioxidants as their quality markers. Voltammetric sensors based on the carbon nanotubes electropolymerized pyrocatechol violet (PCV) or p-aminobenzoic acid (ABA) were developed for simultaneous determination of in cognac brandy. The polymerization conditions PCV ABA optimized. Sensors allow sensitive gallic ellagic acids well syrin...

Synthetic organic dyes were extensively used by artists in the first half of 20th century, knowingly or otherwise. This included Andy Warhol and his À la Recherche du Shoe Perdu (c. 1955), a major portfolio hand-colored prints, copy which resides collection The Museum Modern Art (MoMA). friends known to use Dr. Ph. Martin’s Synchromatic Transparent Water Colors bring these prints life. A histor...

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...

conclusions vo can be presented as a safe, well-tolerated, and effective herbal preparation in patients with chronic insomnia. results improvements in sleep and isi scores were significantly greater in patients after a month receiving vo drop in comparison with before starting treatment (p < 0.05). a few patients reported some complications about vo consumption, most of which were mild and no s...

Skin aging is a slow multifactorial process influenced by both internal as well as external factors. Ultra-violet radiations (UV), diet, smoking and personal habits are the most common environmental factors that affect skin aging. Fat contents and fibrous proteins as collagen and elastin are core internal structural components. The direct influence of UV on elastin integrity and health is centr...
