Feeder is one of the airships of the Multibody Advanced Airship for Transport (MAAT) system, under development within the EU FP7 project. MAAT is based on a modular concept composed of two different parts that have the possibility to join; respectively they are the so-called Cruiser and Feeder, designed on the lighter than air principle. Feeder, also named ATEN (Airship Transport Elevator Netwo...

Chromomycin A3 binds to DNA and Protamine -deficient spermatozoa look bright yellow,whereas normal spermatozoa appear dull yellow.

A machine is described which can perform the Gram stain. Comparison of slides stained by machine versus hand revealed no difference in reproducibility or accuracy. In addition to providing clean, dry, uniformly stained slides, the machine saves 24 sec per slide when compared with a hand staining technique.

A wet-mount technique for staining bacterial flagella is highly successful when a stable stain and regular slides and cover slips are used. Although not producing a permanent mount, the technique is simple for routine use when the number and arrangement of flagella are critical in identifying species of motile bacteria.

This article summarized immunohistochemistry methods generally used in research laboratories and clinic including direct immune staining, indirect immune staining, enzyme method, fluorescence method, APC method and PAP method.

The Golgi staining technique, also called the black reaction after the stain's color, was developed in the 1870s and 1880s in Italy to make brain cells (neurons) visible under the microscope [3]. Camillo Golgi developed the technique while working with nervous tissue, which required Golgi to examine cell structure under the microscope [3]. Golgi improved upon existing methods of staining, enabl...

dental plaque is a well known etiologic factor for gingivitis. recently, herbal extracts are a matter of scientific interest to inhibit plaque accumulation on teeth. the purpose of this study was to evaluate the effects of german chamomile (gc) mouth wash on plaque and gingival indices. twenty five gingivitis patients (15 female and 10 male, mean age 27±7.76 years) participated in this controll...

Background and Objective: Tuberculosis is still a major health problem, involving about 1/3 of the world´s population. Diagnosis is difficult when we only use Ziehl-Neelson staining. Many cases may be missed. A more rapid and sensitive diagnostic method is necessary. PCR may be helpful. The aim of this study was to compare PCR, Zieh-Neelsen staining and histopathologic findings in diagnosis of ...

mens from patients with Hodgkin's disease and five specimens from patients with reactive follicular hyperplasia. The use of chlorazol fast pink BK, a little known stain for eosinophil polymorphs, combined with image analysis facilitated rapid and reliable counting. Significant differences were found between the mean percentages of eosinophil polymorphs in the Rye subtypes of Hodgkin's disease. ...
