JB-4 Kit AGR1130
Unit 7, M11 Business Link Parsonage Lane, Stansted Essex, UK CM24 8GF t: +44 (0)1279 813519 f: +44 (0)1279 815106 e: [email protected] w: www.agarscientific.com JB-4 Kit AGR1130 Introduction: JB-4 Embedding Kit is a unique polymer embedding material that gives a higher level of morphological detail than paraffin processed tissues. A water-soluble media, JB-4 does not require dehydration to absolute alcohol except for dense, bloody, or fatty tissue specimens. JB-4 is excellent for non-decalcified bone specimens, routine stains, special stains, and histochemical staining. Clearing agents such as xylene and chloroform are not required. The polymerization of JB-4 is exothermic, which is easily controlled by polymerizing on ice or by using refrigeration at 4°C. JB-4 Embedding Kits must be used under a chemical fume hood. Sections of JB-4 embedded material can be cut at 0.5 to 3.0 microns or thicker. Microtomes designed for plastic sectioning are required as are glass, Ralph, or tungsten carbide knives. Polysciences, Inc. has tungsten carbide knives available for most sectioning requirements. Sections can be stained for routine histological or histochemical procedures. Immunohistochemical procedures are not recommended for JB-4 as the glycol methacrylate cannot be removed from the section and may block antigen sites for most antibody reactions. As an alternative we recommend the Polysciences, Inc. Osteo-Bed Bone Embedding Kit. The Osteo-Bed formulation is a methyl methacrylate that is well suited for bone or for immunohistochemistry on routine histological specimens. NOTE: It is recommended that the Embedding Kit be used under a fume hood with appropriate gloves. -
I. the Preparation and Morphology of a Quantified Urine Sediment
Upsala J Med Sci 84: 67-74, 1979 The Effect of Short-term High-dose Treatment with Methenamine Hippurate of Urinary Infection in Geriatric Patients with Indwelling Catheters I. The preparation and morphology of a quantified urine sediment Bo Norberg, Astrid Norberg, Ulf Parkhede, Hans Gippert and MBns Akerman Departments of Internal Medicine, Pathology and Education, Univer.tity of Lund and the School of Nursing, Lund, Sweden. 3 A4 Riker Laboratories, Skurholmen, Swyden ABSTRACT A quantified sediment of the urine from patients with indwelling catheters was prepared by fixation of 0.1 ml urine in 0.9 ml 2% glutaraldehyde immediately after sampling. Slide preparations were then made from 0.2 ml of the glutaral- dehyde suspension by means of a cytocentrifuge. Bacteria and epithelial cells were properly contrasted by the May-Grunwald-Giemsa stain but haematoxylin- eosin and the Papanicolaou stain were superior as regards leukocyte morphology. It is suggested that glutaraldehyde-cytocentrifuge preparations of the urine cytology may be useful in the evaluation of urinary infection and in the evaluation of the therapy of urinary infection. INTRODUCTION The microscopic examination of urine sediments is a rapid and simple proce- dure which provides essential information in many cases of kidney disease or infections in the urinary tract. The conventional urinary sediment has, how- ever, serious pitfalls, e.g. low reproducibility, low precision and high vul- nerability to delay in transport and preparation (1-10). It nevertheless seemed desirable to make a quantified urine sediment from patients with indwelling catheters in order to evaluate urinary infection and the effects of therapy. -

The apical epithelial surfaces of mammalian respiratory, gastrointestinal, and reproductive tracts are coated by mucus, a mixture of water, ions, glycoproteins, proteins, and lipids. The purpose of this study was to confirm the presence of mucin production using Haematoxylin and Eosin (H&E) stain as the gold standard and to describe the types of mucins produced in tumors of lung, colon and ovaries using various types of histochemical techniques. Methods: The resection specimens and biopsies from tumours of colon (n=16), ovaries (n=13) and lung (n=5) were included and stained with H&E to determin the histological diagnosis for selecting tissues with mucin production. Slides were stained with PAS, Alcian blue, High iron diamine-Alcian blue, Meyer’s mucicarmine and Alcian blue-PAS to demonstrate the mucin production and to identify types of mucins. Results: In the present study we observed predominance of acid mucins over neutral mucins. In addition in these cases we observed sulphomucin predominating over sialomucin. Conclusion: Mucin histochemistry can effectively determine the types of mucins. Keywords: Haematoxylin and Eosin; Periodic acid schiff; High iron Materials and Methods diamine; Alcian blue Paraffin embedded sections were prepared using automatic tissue Introduction processor, followed by preparation of paraffin block using our embedding station. -

T-Cell Brain Infiltration and Immature Antigen-Presenting Cells in Transgenic Models of Alzheimerв€™S Disease-Like Cerebral
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2016 T-cell brain infiltration and immature antigen-presenting cells in transgenic models of Alzheimer’s disease-like cerebral amyloidosis Ferretti, M T ; Merlini, M ; Späni, C ; Gericke, C ; Schweizer, N ; Enzmann, G ; Engelhardt, B ; Kulic, L ; Suter, T ; Nitsch, R M Abstract: Cerebral beta-amyloidosis, one of the pathological hallmarks of Alzheimer’s disease (AD), elicits a well-characterised, microglia-mediated local innate immune response. In contrast, it is not clear whether cells of the adaptive immune system, in particular T-cells, react to cerebral amyloidosis in AD. Even though parenchymal T-cells have been described in post-mortem brains of AD patients, it is not known whether infiltrating T-cells are specifically recruited to the extracellular deposits of beta-amyloid, and whether they are locally activated into proliferating, effector cells upon interaction with antigen- presenting cells (APCs). To address these issues we have analysed by confocal microscopy and flow- cytometry the localisation and activation status of both T-cells and APCs in transgenic (tg) mice models of AD-like cerebral amyloidosis. Increased numbers of infiltrating T-cells were found in amyloid-burdened brain regions of tg mice, with concomitant up-regulation of endothelial adhesion molecules ICAM-1 and VCAM-1, compared to non-tg littermates. The infiltrating T-cells in tg brains did not co-localise with amyloid plaques, produced less interferon-gamma than those in controls and did not proliferate locally. Bona-fide dendritic cells were virtually absent from the brain parenchyma of both non-tg andtgmice, and APCs from tg brains showed an immature phenotype, with accumulation of MHC-II in intracellular compartments. -

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. -

It is a pH indicator as well, changing color from red to yellow over the pH range 6.8-8.0. It is also incorporated into bacteriological growth media. This product is often used for supravital staining of fresh peripheral blood. It can also be used for staining Nissl granules of neuroglial cells. However, this stain is not as permanent as another dye, Cresyl Violet acetate, for this application. Buffered 0.5% Neutral Red solutions are used as a counterstain for Naphthol AS acetate esterase, peroxidase and iron stains. Solutions can also be used to stain plankton for viability. Using 1 part Neutral Red to 10,000 parts sea water, dead cells were stained red and live cells remained unchanged. In addition, aqueous solutions of Neutral Red (0.1% in saline, pH 6.5) can be used as a fluorescent stain for lipids. Lipids will fluoresce blue-geen or yellow, depending on their composition. It has been used also as a Twort's stain for parasites in combination with Light Green SF, as a general histological stain for embryonic tissue in combination with Janus green,and for demostrating hydrolysis of fats. -

Susumu Hibino) Because of potent activities of respiratory enzymes found in isolated mito- chondria, morphological changes in mitochondria have again attracted attention as indicative of cell's functional potentialities. Mitochondria in the cell can be visualized by employing, 1) Altmann's stain- ing method or Heidenhain's iron hematoxylin stain on fixed preparations, 2) the supravital staining method using Janus green, and recently 3) the supravital observation by means of the phase contrast microscope. Among these, the supravital method with Janus green is widely employed because of its simplicity and high specificity. But this Janus green method is not free from faults : namely difficulty in differentiating the types of cells and quick fading of the stained mitochondria. In 1936 Hetheringtonl) introduced a dyestuff named pinacyanole into the su- pravital staining method of mitochondria, and this method has been investigated by J. L. Schwind,2) showing that nuclei are stained supravitally and the types of cells are easily differentiated, stainability of neutral red vacuoleg is not dis- turbed and the colored mitochondria do not fade away for several hours. This pinacyanole (Consolidated Midland Corporation) and vital neutral red have been obtained lately, and we are discussing the usefulness of the former dyestuff in the study of mitochondria, comparing it with the above-mentioned various mitochondrial methods, and the nature of its staining mechanism. -
Commercial Fisheries Review
May 1957 - Supplement COMMERCIAL FISHERIES REVIEW DYE-BINDING CHARACTERISTICS OF FISH-MEAL PROTEIN Part 1 - Some Preliminary Findings as to Suitable Dyes By Claude Thurston A: ABSTRACT THERE ARE REPORTS IN THE SCIENTIFIC LITERATURE THAT THE QUALITY OF A VEGETABLE PROTEIN CAN BE DETERMINED BY ITS DYE-BINDING CHARACTERIS- TICS. IN AN INVESTIGATION TO FIND IF A SIMILAR RELATIONSHIP EXISTS BE- TWEEN DYES AND THE PROTEIN IN FISH MEAL, MORE THAN 100 DYES WERE SCREENED AS TO THEIR SUITABILITY. EIGHT DYES WERE FOUND TO HAVE GOOD BINDING PROPERTIES. SIX OF THEM--AC1D FUCHSIN, ANILINE BLUE, BROMO- CRESOL GREEN, ALIZARIN RED S, ORANGE II, AND ORANGE G--WERE ACID DYES; AND TWO OF THEM--CONGO RED AND T ETRABROMOPHENOLBLUE--WERE BASIC DYES. IN THE USE OF THESE, FISH MEALS EXHIBITED A WIDE VARIATION IN THE EX- TENT OF DYE BINDING. SUFFICIENT DATA, HOWEVER, ARE NOT AVAILABLE AS YET TO DETERMINE THE RELATIONSHIP OF THE DYE-BINDING CHARACTERISTICS TO THE NUTRITIVE VALUE OF FISH-MEAL PROTEIN. INTRODUCTION Several of the investigations reported in the scientific literature indicate that the quality of a vegetable protein can be determined by its dye-binding characteris- tic. Loeb (1922), studyingthe process of digestion, stated that pepsin is an anion and that it combines with cations. Chap- man, Greenberg, and Schmidt (1927) show- ed, by reactions of several acid dyes with various protein solutions, that the amount of dye that was bound was proportional to thenumber of basic groups in the protein. Rawlins and Schmidt (1929) extended the investigation to include basic dyes and obtained similar results; they later (1930) used acid dyes with gelatin granules and gelatin solutions and verified their pre- vious conclusions.
