Une technique de lecture d'age des raies
Provedor de dados: 5
Autores: Du Buit, M; Maheux, F.
Description of a technique for including and preparing small cross sections of ray vertebra. The observation of the rings growth is performed after staining with cobalt nitrate and safranine. This method is applied to the observation of the growth rings in the vertebra of Raja naevus.

Understanding otolith biomineralization processes: new insights into microscale spatial distribution of organic and mineral fractions from Raman microspectrometry
Provedor de dados: 5
Autores: Jolivet, Aurelie; Bardeau, J.f.; Fablet, Ronan; Paulet, Y.m.; De Pontual, Helene.
It is generally accepted that the formation of otolith microstructures (L- and D-zones) and in particular the organic and mineral fractions vary on a daily basis. Raman microspectrometry provides a nondestructive technique that can be used to provide structural information on organic and mineral compounds. We applied it to thin otolith sections of hake in order to address the following issues: (1) the simultaneous characterization of variations in the organic and mineral fractions both in the core area and along successive otolith microstructures; (2) elucidation of significant differences between these fractions; (3) quantification of the effects of etching and staining protocols on otolith structures. The primordium appeared as a punctual area depicting...

Contemporary Staining of Arterial System with Cadaver Fixation: An Experimental Study
Provedor de dados: 77
Autores: Ghorbani,Rostam; Tavakol,Zahra; Ghanbari,Ali.
Although many methods are investigated, cadavers have unique role for education of gross anatomy. This study was performed to make cadaveric based gross anatomy more enjoyable and decrease the time needed for achievement of arterial system for teachers and learners. The adult rabbits in control (n=3) and experimental groups (n=9) sacrificed following deep anesthesia. The samples were fixed by injection of fixative solution to the left ventricle and the corps dropped to the traditional fixative liquid for at least 1 month. The injected fixative solution of experimental group contained stained human red blood cells. The red blood cells stained by eosin (0.25% in saline) for 30 minutes and injected between two injections of fixative. After passing the period...

A Study of the Staining Effect of Roselle (Hibiscus sabdariffa) on the Histologic Section of the Testis
Provedor de dados: 77
Autores: Egbujo,E. C.; Adisa,O. J; Yahaya,A. B.
This study describes the preparation and use of Roselle (Hibiscus sábddariffa) for the differential staining of testicular tissue sections to find out its staining effect on nuclear, cytoplasmic and other structures. Various treatments using modifications of the plant extract in water were carried out on sections of the rabbit testis. Various levéis of differentiation of nuclear and cytoplasmic structures as well as other structures of this organ was obtained especially when 1% eosin was applied as a counter stain. The best staining result was obtained when iron alum was used to mordant the extract and when the extract, mordanted with potassium alum was acidified using acetic acid and used to stain the sections. Modification of the aqueous extract to an...

On the need for independently estimating organic tripton carbon content
Provedor de dados: 27
Autores: Pissierssens, P.; Bergmans, M.; Polk, Ph.
A method is described by which the contribution of Non-Living Particulate Organic Matter (NLPOM) to Total Organic Matter can be determined. The dye Trypan Blue stains only dead organic matter. The surface of the stained particles is used as an indirect measure of the NLPOM-carbon content. Applying this method, it is shown that the bivariate linear regression of POM on chlorophyll &lt;i&gt;a&lt;/i&gt; may produce serious errors in the calculated NLPOM contribution when carbon which is neither tripton- nor chlorophyll-related is present in appreciable quantities.

ธาตุสังกะสีในเมล็ดข้าวพันธุ์พื้นเมืองภาคใต้
Provedor de dados: 106
Autores: Nantiya Panomjan; Chanakan Promuthai; Sansanee Jamjod; Benjavan Rerkasem.
Variation in zinc (Zn) concentration in the grain of 50 local rice varieties from Southern Thailand was examined by diphenyl thiocarbazone (DTZ) staining (intense, medium, low, and nil) and chemical analysis. Intense staining was found in the aleurone layer of 94% of the varieties, in the embryo 56% of the varieties and endosperm 12% of the varieties. Variation was found in the DTZ staining intensity of the embryo and endosperm of individual grains, with Shannon-weaver diversity index (H) of the DTZ staining at 0.15-1.00 for the embryo and 0.00-1.00 for the endosperm. Chemical analysis found the Zn concentration in brown rice grain ranging between 18-34 mg Zn/kg, 7 varieties were considered high grain Zn (29-34 mg Zn/kg). The Zn concentration in the husk...

Exudate - phenolphthalein pH test for evaluation of validity in seeds of Libidibia ferrea
Provedor de dados: 42
Autores: SOUTO,PRISCILA C.; GONÇALVES,EDILMA P.; VIANA,JEANDSON S.; SILVA,JÚLIO C.A.; FERREIRA,DÉBORA T.R.G.; RALPH,LIDIANA N.
Abstract: Seed companies are looking for promising, quick and effective alternatives to determine the physiological quality of seeds. The objective of the current work was to study the efficiency of the exudate - phenolphthalein pH test to evaluate the seeds of two lots of Libidibia ferrea (Mart. ex Tul.) L. P. Queiroz var. ferrea. The statistical design for the the exudate - phenolphthalein pH test was completely randomized with four replicates of 50 seeds in a factorial design (2 x 5), two seed lots and five soaking periods (30, 60, 90, 120, and 150 minutes), respectively, using two constant temperatures (25 and 30°C). The percentage of viability and germination of the seeds did not differ in the temperatures of 25 and 30°C and in the soaking periods by...
