1. Introduction Microscopy is an essential technique not only in cell biology but natural science as a whole. We compared different types of microscopic techniques ‚ according to the specimen used and the scope of the experiment. Two specimens‚ stained and unstained‚ containing CHO cells‚ were prepared‚ examined and analyzed under the microscope using bright field (HF)‚ dark field (DF) and phase contrast (PH) settings. In addition‚ the four phases of cell division cycle were estimated.. Bright

indistinguishable from Gram-positive bacteria. Within prokaryotes‚ only these two groups of organisms are bounded by a single unit lipid membrane‚ and they generally contain a thick sacculus of varying chemical composition. Some Archaea also show positive Gram staining and a few of them‚ similar to certain Gram-positive bacteria‚ do not contain any cell wall (Bacterial‚ 2006). The similarity between Archaea and Bacteria extends to numerous other characteristics including‚ their cellular size which is much smaller

Corrosion Let metal sit surrounded by oxygen for a while and the metal will corrode. Corrosion is the chemical reaction that takes place when a metal is in contact with oxygen. The metal reacts with the oxygen to form a compound called an oxide on the surface of the metal. The metal becomes tarnished and loses its shine. Metals high in the reactivity series (an observable series of metals‚ in order of reactivity from highest to lowest) corrode more quickly than less reactive metals

You Will Need to Limit Certain Foods Another thing you should know is that you will need to limit your intake of certain foods. Items that are staining‚ such as coffee and wine should be limited. Additionally‚ keep sugary foods and drinks to a minimum. Why? Because these items can stain your teeth and your trays. 4.

identification of serous-type acinar differentiation and the absence of epidermoid and mucinous cells distinguishes acinic cell carcinoma from these other neoplasms. For diagnostically difficult cases‚ periodic acid Schiff (PAS) plus diastase‚ a special staining technology‚ can be used as an ancillary histochemical marker to highlight the cytoplasmic zymogen granules characteristic of acinar cells.

To help describe normal and abnormal white blood cells in detail‚ Paul Ehrlich‚ an American biologist‚ developed a technique of staining blood films in 1877 (The Hematologist). His contribution to the world of leukemia allowed doctors to more easily and accurately analyze the white blood cells of
