BACKGROUND Viola odorata L. belongs to Violaceae family and is native to Iran. It is used in the form of Almond-Violet oil in traditional Persian medicine (TPM) since ancient times. Almond-Violet oil was used for the treatment of insomnia, headache, cough, and fever based on TPM textbooks. There are two methods for the preparation of Almond-Violet oil. The first is macerating voila flowers in s...

Several studies have validated the effectiveness of narrow-band imaging (NBI) in estimating invasion depth of early colorectal cancers. However, comparative diagnostic accuracy between NBI and chromoendoscopy remains unclear. Other than crystal violet, use of acetic acid as a new staining method to diagnose deep submucosal invasive (SM-d) carcinomas has not been extensively evaluated. We aimed ...

PURPOSE To examine the viability and differentiation of retinal pigment epithelial (RPE) cells after exposure to the vital dye Acid Violet-17 (AV-17). METHODS Bovine RPE cells were incubated with AV-17 (0.0625-0.5 mg/mL) for 30 seconds or 5 minutes. Viability was determined by live/dead staining, cleaved CASP3 immunostainings, and MTT test. Actin cytoskeleton was visualized by Alexa 488-phall...

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...

The removal of dyes from wastewater is one the biggest problems in textile industry for
 both environment and manufacturers. This study examined possibility applying ozone 
 (O3) O3 combination with ultraviolet (UV) to treat a mixture synthetic containing five different (Acid Red 17, Acid Yellow 11, Direct 12, Blue 86 Mordant Violet 40) for decolorization efficiency chromophore anchor...

Rhododendron is one of the largest shrubs and is well known as a garden plant because of their evergreen leaves and various flower colors. The present study investigated the variation in amino acids in the differently colored flowers of Rhododendron schlippenbachii. Analysis of the Rhododendron flowers revealed 22 types of amino acids. The amino acid content varied greatly depending on the diff...

the clay crosslinked hydrogel nanocomposites were synthesized by graft copolymerization of acrylamide and itaconic acid in the presence of different amounts of laponite using ammonium persulfate and n,n,n',n'-tetramethylethylene diamine  )temed) as a free radical initiator and catalyst, respectively. the xrd patterns of nanocomposites showed that the clay layers are completely exfolia...

1. Acid fuchsin possesses a bactericidal power, selective as between Gram-negative and Gram-positive spore-bearing aerobic organisms. The selective feature is the reverse of that of gentian violet. 2. This reverse selective activity is also possessed by simpler sulfonated substances and would appear to be dependent in some way on the presence of SO(3) radicals. 3. Selective penetration, if at a...
