Gonçalves 1,* 1 Centre of Chemistry, University of Minho, Campus of Gualtar, 4710-057 Braga, Portugal 2 Centre of Molecular and Environmental Biology, University of Minho, Campus of Gualtar, 4710-057 Braga, Portugal * Correspondence: [email protected] † Presented at the 22nd International Electronic Conference on Synthetic Organic Chemistry, 15 November– 15 December 2018; Available Online: https://sciforum.net/conference/ecsoc-22. Published: 14 November 2018 Abstract: The synthesis of four new Nile Blue derivatives with hydrogen, propyl and/or aminopropyl groups as substituents of the amines of 5- and 9-positions is described. Photophysical properties were evaluated in acidified ethanol and aqueous solution at physiological pH. Antifungal activity is also studied through the obtention of MIC values. Keywords: benzo[a]phenoxazines; Nile Blue derivatives; NIR fluorescent probes; antifungal agents 1. Introduction The development of new near-Infrared (NIR) fluorescent probes is a very important issue due to the wide range of applications [1–4]. These probes are an excellent choice to label biological material since its emission will not interfere with the natural fluorescence of biological compounds. Benzo[a]phenoxazinium salts, with Nile Blue being the best known, display fluorescence at around 600 nm and have been used as covalent and non-covalent fluorescent probes for amino acids, proteins and DNA, among other biological material [5–10]. In addition, applications as sensors or agents for photodynamic therapy (PDT) have been described [11,12]. -
A Study of Rawitz's 'Inversion Staining' by ALEKSANDRA PRZEL^CKA
231 A Study of Rawitz's 'Inversion Staining' By ALEKSANDRA PRZEL^CKA {From the Cytological Laboratory, Department of Zoology, University Museum, Oxford, and the Nencki Institute, 3 Pasteur St., Warsaw 22; present address, Nencki Institute) SUMMAHY The Rawitz method involves mordanting with tannic acid and potassium antimony tartrate, and staining with basic fuchsine. The mordanting causes basic fuchsine to act as though it were an acid dye ('inversion staining'). A modification of the method is described in the present paper. This modification makes it possible to obtain the same results in a shorter time. The chief substances stained by Rawitz's method are phospholipids, certain pro- teins, and certain polysaccharides. Although the method cannot be regarded as a cytochemical test in the strict sense, yet it gives useful indications of chemical composition and in addition is valuable to the morphological cytologist as a technique for showing certain cytoplasmic inclusions (mitotic spindle, acrosome, mitochondria, 'Golgi apparatus' of certain cells). INTRODUCTION T is well known that the so-called 'Golgi apparatus' is extremely difficult to I reveal by any staining method. Baker, in the course of his investigation on this organelle in the epididymis of the mouse, found that it can be stained by basic fuchsin after a special mordanting process (1957). The method was taken from Rawitz (1895), who found that basic fuchsin, if mordanted with tannic acid and potassium antimony tartrate, loses the character of a dye for chro- matin and colours the cytoplasm instead. Rawitz called this effect 'inversion staining'. Since this technique, when applied to various kinds of cytological material, gave good selectivity in visualizing certain delicate cell structures, it seemed interesting to investigate the nature of the chemical compounds which are responsible for positive Rawitz staining. -

Factors Affecting the Adsorption of Some Ionic Dyes on the Surface of Modify Cao from Eggshell
Asian Journal of Applied Sciences (ISSN: 2321 – 0893) Volume 07 – Issue 01, February 2019 Factors Affecting the Adsorption of Some Ionic Dyes on the Surface of Modify CaO from Eggshell Ibtighaa K. Radhi, Mouayed A. Hussein, Zaki N. Kadhim* Department of Chemistry, College of Science, University of Basrah Basrah, Iraq *Corresponding author’s emails: zekinasser99 [AT] yahoo.com ________________________________________________________________________________________________ ABSTRACT--- In this paper, calcium oxide (CaO) was produced by the thermal treatment of eggshell. The doping process with silver iodide (AgI), oxygen (O), sulfur(S) and nitrogen (N) was achieved by adsorbents. The adsorption of Acid fuchsine (AF), Indigo Carmine (IC), Nigrosine (NG) and Alizarine Red S (AR) on the surface of these particles was studied. The different conditions affecting the adsorption process, such as the time of equilibrium, the primary concentration of the studied dyes, the amount of the adsorbent, the acidic function, the speed of the pruning motion and the temperature were studied. The pH stability time (5-10 minutes), IC and NG (30 minutes) and AR were (90 minutes). The effect of temperature was also studied within the range (25-45 ° C). The results showed that the adsorption capacity increased by increasing the temperature, ie the reaction is endothermic. The study showed the effect of the acidic function on the percentage of pigmentation. The percentage was increased by increasing the acidic function in the basal circles on the surfaces except for the AR dye. It decreased the percentage by increasing the acidic function. The effect of the weight of the adsorbent was studied on the percentage of adsorption. -
Toluidine Blue Stain and Crystal Violet Stain Versus H&E Stain in the Diagnosis of Hirschsprung’S Disease : a Study in Sulaimani City in Kurdistan/Iraq Hadeel A
Original Article Toluidine Blue Stain and Crystal Violet Stain Versus H&E Stain in the Diagnosis of Hirschsprung’s Disease : A Study in Sulaimani City in Kurdistan/Iraq Hadeel A. Yasseen Department of pathology, School of Medicine, University of Sulaimani. Iraq Keywords: Hirschsprung’s Disease, Ganglion Cells, Cresyl Violet, Toluidine Blue, Mast Cells ABSTRACT Background: Hirschsprung’s Disease (HD) is a congenital disorder of the colon in which certain nerve cells, known as ganglion cells are absent. Setting and Design: To demonstrate the efficacy of Cresyl Violet and Toluidine blue (Tb) special stains in the identification of ganglion cells in suspected Hirschsprung’s disease and to find other adjuvant histological criteria for the diagnosis. Method: In Sulaimani Teaching Hospital and Pediatric teaching hospital in Sulaimani Governorate/ Kurdistan-Iraq a total of fifty non selected cases biopsied for suspected HD were stained with hematoxylin and eosin (H&E) stain and divided into two groups: HD and-non-HD. All cases then should be stained with Tb special stain to identify ganglion cells and to count mast cells in the submucosa. Cases were stained with Cresyl Violet special stain to identify ganglion cells. H&E- and Tb-stained sections were examined for the presence or absence of hypertrophic nerve fibers in the submucosa. Results: Both Cresyl violet and Tb stains were superior to H&E in the identification of ganglion cells with no statistically significant difference between the two stains. Mast cell count in the submucosa has no important effect on diagnosis while nerve bundle hypertrophy was found to be associated with absence of ganglion cells in Hirschsprung disease. -
Nile Blue Is a Basic Dye of the Oxazine Group, Which Has Been Used in Several Microscopic and Histochemical Techniques (4, 6)
ACTA HISTOCHEM. CYTOCHEM. Vol. 16, No. 3, 1983 LETTER TO THE EDITOR NILE BLUE SULFATE STAINING FOR DEMONSTRATION OF LIPIDS IN FLUORESCENCE MICROSCOPY Nile blue is a basic dye of the oxazine group, which has been used in several microscopic and histochemical techniques (4, 6) . A staining method based on application of Nile blue sulfate was introduced early for the cytochemical demon- stration of lipids (3, 8, 9), showing neutral fats and fatty acids in red and blue, respectively. There is evidence (1, 10) that aqueous solutions of Nile blue sulfate contain the blue cation of the dye, a red oxidation product (Nile red), and the orange-red imino base. According to this view, phospholipids and fatty acids stain blue because they react with the Nile blue cation, meanwhile neutral fats appear in red color. Other observations seem to be in disagreement with this staining mecha- nism (5, 6) . A fluorescence reaction in tissues after staining with Nile blue sulfate and brilliant cresyl blue has been found by Bozzo and Campos Vidal (2). During the course of investigations by using oxazine dyes we have observed that Nile blue sulfate produces a strong fluorescence reaction in lipid droplets. The fat body of Drosophila larvae is a continuous tissue mass which has been chosen as test material because of its abundance in lipidic inclusions. Drosophila hydei testes, surrounded by the fat body, were fixed in 5 % formaldehyde for 1-24 hr, washed, and then immersed in 0.1 mg/ml aqueous Nile blue sulfate (Fluka) for 30 min. After staining, the material was briefly washed and mounted with a drop of water. -

Overcoming Cloning Problems by Staining Agarose Gels with Crystal Violet Instead of Ethidium Bromide in Lactate Dehydrogenase Ge
Acta Biologica Hungarica 56 (3–4), pp. 389–397 (2005) OVERCOMING CLONING PROBLEMS BY STAINING AGAROSE GELS WITH CRYSTAL VIOLET INSTEAD OF ETHIDIUM BROMIDE IN LACTATE DEHYDROGENASE GENE FROM PLASMODIUM VIVAX AND PLASMODIUM FALCIPARUM D. TURGUT-BALIK,1* V. ÇELIK,1 KATH MORETON2 and R. L. BRADY2 1 Department of Biology, Faculty of Arts and Sciences, University of F°rat, Elaz°=, Turkey 2 Department of Biochemistry, University of Bristol, University Walk, Bristol BS8 1TD, U.K. (Received: August 9, 2004; accepted: November 9, 2004) In this study, lactate dehydrogenase gene from Plasmodium vivax has been tried to subclone into an expression vector. Some of the Plasmodium falciparum lactate dehydrogenase mutant genes have also been tried to clone and subclone into a vector, but we failed to clone or subclone either of the genes. DNA visualisation in electrophoretic gels typically requires UV radiation and the fluorecent dye ethidium bro- mide. A crystal violet-stained gel was run instead of an ethidium bromide gel and so avoided the use of UV radiation. This enabled us to clone or subclone both Plasmodium vivax lactate dehydrogenase gene and Plasmodium falciparum lactate dehydrogenase mutant genes into any desired vector. Keywords: Plasmodium vivax – Plasmodium falciparum – lactate dehydrogenase – crystal violet – ethid- ium bromide INTRODUCTION Drug resistance of Plasmodium to currently available antimalarials is increasing throughout the world. Discovery of a new, effective, safe, permanent and inexpen- sive antimalarial is essential to overcome this problem. The enzyme lactate dehydrogenase (LDH) has been targeted for the design of a novel antimalarial drug. It is a vital enzyme for the malarial parasite. -
A Consideration of the Term Gloeocystidium
April 1976 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 28(1): 123-130 A CONSIDERATION OF THE TERM GLOEOCYSTIDIUM MICHAEL J. LARSEN AND HAROLD H. BURDSALL, JR. Center for Forest Mycology Research, Forest Products Laboratory, Forest Service, U. S. Department of Agriculture, Madison, WI 53705 Structures termed “gloeocystidia” occur in diverse genera throughout the major groups of Homobasidiomycetes and have been variously defined: Ainsworth et al. (1971) state that it is a cystidium “that is thin-walled, usually irregular and with highly refractive hyaline or yellowish contents.” Snell and Dick ( 197 1) list the variant spelling “gleocystidium” with the definition, “A special form of cystidium in Hymenomycetes, of gelatinous or horny consistency and with oily, resinous, or granular contents.” Talbot (1954) and Price (1975) have provided comprehensive statements on the concept of gloeocystidia. We present a condensed version here of Talbot’s (1954, p. 288) definition. Sterile organs, with thin walls; lack of sculpturing and encrustation; contents hyaline to brownish, highly refractive, homogeneous, granular, or oily; aris ing from subhymenial and contextual tissues; staining deeply in phloxine and eosine in KOH mounts and becoming brown in iodine solutions. In 1944, Romagnesi proposed the term “macrocystide” for a cystidial form in the “Lactario-russulés,” and these cystidia (macrocystidia) were described as “trés longue . fusiform ou claviforme, souvent terminée par une pointe ou un appendice variable; son pédicule est très long et souvent en connexion avec laticifères de la trame,” and secondly “très souvent, mais non toujours, devient gris-bleu ou noirâtre . au contact de la sulfovanilline. .” Romagnesi’s ( 1944) interpretation of macrocystidia is apparently based primarily on form, and secondarily on the chemical reaction with sulfovanillin. -
Magenta and Magenta Production
MAGENTA AND MAGENTA PRODUCTION Historically, the name Magenta has been used to refer to the mixture of the four major constituents comprising Basic Fuchsin, namely Basic Red 9 (Magenta 0), Magenta I (Rosaniline), Magenta II, and Magenta III (New fuchsin). Although samples of Basic Fuchsin can vary considerably in the proportions of these four constituents, today each of these compounds except Magenta II is available commercially under its own name.

Marking Tephritidae Fruit Fly Adults in Hawaii for Release-Recovery
Vol. XXIII, No. 3, February, 1981 437 Marking Tephritidae Fruit Fly Adults in Hawaii for Release-Recovery Studies1234 W. J. SCHROEDER5AND W. C. MlTCHELL6 The need to identify released insects is paramount in studies based on release-recovery evaluations. In Hawaii identification of released oriental fruit flies, Dacus dorsalisHendel, is accomplished by rearing and releasing phenotypically distinct flies (Steiner et al, 1962). Presently, marking the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), and the melon fly, D. cucurbitae Coquillett, is accomplished with the use of Calco Blue ® dye (Steiner, 1965), Blaze Orange Day-Glo® fluorescent dye (Holbrook et al, 1970) or Tinopal® SFG fluorescent whitening agent (Schroeder et aL, 1972). Because of the need for additional markers, we routinely examine dye materials as possible external (ptilinum dye) and internal (vital dye) markers. These continuing studies include coating pupae with dye powder to determine the potential of the material as an external adult dye and addition of the dye to the larval diet followed by examination of the adult to determine the potential of the material as a vital dye. Promising mate rials are then evaluated for retention by the insect and ease of detection, and dyed insects are examined for behavioral changes. Finally the material is evaluated in a field release-recovery test. This report describes the general procedure used in dyeing and examining adult flies for the marker, lists materials tested, and discusses dyes presently used in Hawaii. General.—Adult Tephritidae are marked with an external dye by tum bling a known quantity of pupae with a known quantity of dry powder.
