Direct red 81 and amido black stain proteins in polyacrylamide electrophoresis gels within 10 min.
Anal. Biochem. 400(1) , 139-41, (2010) Proteins separated by SDS-polyacrylamide gel electrophoresis can be stained with organic dyes, the most popular being Coomassie brilliant blue R-250. Coomassie R-250 staining of ovalbumin in an SDS-PAGE gel increased linearly from 2.5 to 60 min. Direct red 81... |

Rapid detection of proteins in polyacrylamide electrophoresis gels with Direct Red 81 and Amido Black.
Methods Mol. Biol. 869 , 585-9, (2012) Proteins separated by SDS-polyacrylamide gel electrophoresis need to be stained with organic dyes to be visualized and to enable comparisons to be made between the intensity of protein bands to observe and determine differences in protein concentration. The s... |

The structure of the bilaminar zone in the human temporomandibular joint: a light and scanning electron microscopy study in young and elderly subjects.
J. Oral Rehabil. 28(2) , 113-9, (2001) The bilaminar zone (BZ) in the human temporomandibular joint (TMJ) of toothed adults (GI) and toothless, elderly humans (GII) were analysed using light and scanning electron microscopy (SEM). In both groups the BZ consists of an upper and a lower stratum of c... |

Characterization of a novel model of pancreatic fibrosis and acinar atrophy.
J. Gastrointest. Surg. 3(4) , 418-25, (1999) Significant fibrosis and acinar atrophy are characteristics of chronic pancreatitis; however, because of the lack of a reproducible model, early phases of these changes are poorly understood. We have developed a model of severe hyperstimulation and obstructio... |

Image segmentation of liver fibrosis.
J. Microsc. 231(Pt 1) , 70-80, (2008) Quantitation of connective tissue versus parenchymal tissue compartments is important in assessment of fibrosis (scarring) and its progression in liver disease. This paper presents a two-step algorithm for quantifying fibrosis in liver biopsies stained with S... |

Comparison of photocatalytic degradation of dyes in relation to their structure.
Environ. Sci. Pollut. Res. Int. 20(6) , 3570-81, (2013) The photocatalytic degradation of a series of six acid dyes (Direct Red 80, Direct Red 81, Direct Red 23, Direct Violet 51, Direct Yellow 27, and Direct Yellow 50) has been tested compared in terms of color removal, mineralization, and toxicity (Lactuca sativ... |

[Connective tissue of the human fallopian tube mucosa--polarization microscopic detection of collagen using Solaminrot 4B].
Acta Histochem. 86(2) , 159-66, (1989) The Picrosirius-polarization method was applied to the selective morphological collagen detection in the human uterine tube. Solaminrot 4B (VEB Chemiekombinat Bitterfeld) was used as dyestuff which enhances the normal birefringency of collagen fibrous materia... |

[Analytical dye studies on the polarization microscopic detection of collagen with Solaminrot 4B. I].
Acta Histochem. 89(2) , 237-44, (1990) It is known that the birefringency of the collagen fibres is selectively enhanced by staining with Sirius Red. According to experiences, the most authors usually take Sirius Red F3BA as dye. We use the disazo dyestuff Solaminrot 4B produced by VEB Chemiekombi... |

[Dye analytical investigations on the polarization microscopy detection of collagen with Sominrot 4B (Part II)].
Acta Histochem. 90(1) , 75-85, (1991) We use the disazo dyestuff Solaminrot 4B for the visualization of collagen fibres in the morphological substratum investigated. The dye selectively enhance the birefringency of the fibres. Therefore, the parts of this paper are dealing with the dye properties... |

Histopathological changes of the heart after neonatal dexamethasone treatment: studies in 4-, 8-, and 50-week-old rats.
Pediatr. Res. 66(1) , 74-9, (2009) Dexamethasone (Dex), for prevention of chronic lung disease in preterm infants, showed potential negative long-term effects. Studies regarding long-term cardiovascular effects are lacking. We investigated possible histopathological myocardial changes after ne... |
