Alizarin red, confocal laser scanning microscopy, dentinal tubules, human caries. Abstract Dentin morphology and the lesion found in dental caries have been studied for many years. It was first observed under optical microscopy, and later using electron microscopy. Confocal laser scanning microscopy (CLSM) applied with several fluorescent dyes such as alizarin red to see normal dentinal tubules...

background & aim: rubiatinctorum is one of the most well-known medicinal plants whose alizarin and other anthraquinones which are outstanding color agents with some trace of pharmaceutical properties are isolated from it. the objective of this study was to optimize alizarin production in intact plant of r.tinctorum by induction with biotic elicitors. experimental: to increase the synthesis ...

abstract purpose: skeletal staining is a way to study the effect of many chemical or herbal substances on development of bones and cartilages in order to record the level of probable deformity.this article aimed to present a modified protocol to make all skeletal studies on laboratory animals possible. materials and methods: the important notes about skeletal staining were fixing by ethanol and...

Staphylococcal biofilms are problematic and play a critical role in the persistence of chronic infections because of their abilities to tolerate antimicrobial agents. Thus, the inhibitions of biofilm formation and/or toxin production are viewed as alternative means of controlling Staphylococcus aureus infections. Here, the antibiofilm activities of 560 purified phytochemicals were examined. Ali...

An extraction method of madder (Rubia tinctorum) roots dyes is established and optimized to obtain the original chemical composition. A central composite design (CCD) was developed to specify the importance of the three major factors studied (time, temperature and solvent composition) affecting the ultrasound-assisted extraction of this matrix. A preliminary granulometric study of madder roots ...

The photocatalytic degradation of dyes (alizarin red S, amaranth, congo red, and rhodamine B) present in wastewater was performed with UV lamp. catalysts employed for this investigation were ZnO, TiO2, SnO2. kinetic studies followed first order reaction. ZnO found to be most efficient photo-catalyst degrading these dyes. optimal result alizarin S k = 0.2118 min?1, t1/2 3.27 min, R2 0.7998, amar...

In a 2-year study, fruit from eight redand eight yellow-skinned ‘White Angel’× ‘Rome Beauty’ hybrid selections were stored for 21 weeks at 0.5°C plus 1 week at 20°C and evaluated for the incidence and severity of superficial scald. Five red-skinned (R-03, R-20, R-22, R-48 and R-85) and three yellow-skinned (Y-26, Y-55 and Y-65) selections were examined in both seasons. Peel-tissue samples taken...

Tomato (Solanum lycopersicum) fruit accumulate the red carotenoid pigment lycopene. The recessive mutation yellow-flesh (locus r) in tomato eliminates fruit carotenoids by disrupting the activity of the fruit-specific phytoene synthase (PSY1), the first committed step in the carotenoid biosynthesis pathway. Fruits of the recessive mutation tangerine (t) appear orange due to accumulation of 7,9,...
