neurogenic changes. Many myofibers with multiple clusters of blue red rod-like structures and cytoplasmic inclusions were noted. Immunohistochemistry showed a focal positive reaction in sarcoplasm to desmin and myotilin antibodies. An electron microscope study revealed variable abnormalities of myofibrillar structures. To the best of our knowledge‚ this is the first reported case of MFM with pathology findings in Korea. Key Words : Myofibrillar myopathies; Desmin; Pathology CASE REPORT

Unit II Test Review Chapter 4 BB Notes Cells Under the Microscope Cells are microscopic in size. Although a light microscope allows you to see cells‚ it cannot make out the detail that an electron microscope can. The overall size of a cell is regulated by the surface-area-to-volume ratio. 4.2 The Plasma Membrane The plasma membrane of both prokaryotes and eukaryotes is a phospholipid bilayer. The phospholipid bilayer regulates the passage of molecules and ions into and out of the cell. The

Electron Microscopy The electron microscope is a very powerful microscope which can see things that normal microscopes cannot. There are 2 types of electron microscope: the transmission electron microscope and the scanning electron microscope. The sample must be in a vacuum so that no air bubbles are on the produced image and also because the electrons are absorbed by the molecules in the air‚ this means that the electron microscope cannot be used to look at living cells. The tissue is soaked

It wasn’t until 1962‚ Rosenburg incorporated the business as Tyco Laboratories. The company’s focus was on energy conservation products and tech materials science for commercial use. In September 1964 Tyco went public and began its acquisition of other companies to enlarge

Microscope Microscopes are instruments that produce a magnified image of a small object. They are used in many scientific and industrial applications. Some common applications for microscopes include manufacturing inspection and high-technology quality control. Specific quality control applications for microscopes include semiconductor processing‚ medical imaging‚ cell research‚ and metallurgical analysis. Microscopes are supplied in one of three common configurations‚ student‚ benchtop‚ and research

administration. There are several methods that can be used to investigate the size and shape of particles. These range from basic (generally older) techniques such as sieving and use of optical microscopes through to more advanced techniques‚ such as using a coulter counter‚ a scanning electron microscope or photon cross correlation spectroscopy. You will cover a range of techniques in the lectures that accompany this section of the module and you should refer to your lecture notes for further details

Review Questions What is a comparison microscope? What are the advantages of this microscope? A comparison microscope combines two microscopes into one. It allows the viewer to see what is under each of the lenses at the same time. This is helpful when examining a known sample in forensic scinece.

Review Questions 1. What is a comparison microscope? What are the advantages of this microscope? A comparison microscope is a type of microscopes that is commonly used in a forensic laboratory. This microscope combines two microscopes into one unit‚ allowing the viewer to see what is under each of the lenses at the same time. This is a huge advantage because it allows you to compare evidence with a known sample because the two samples can be examined side by side. 2. What are the three substances
