PTK7 Regulates Epididymal Duct Coiling Through Regulating Myosin II Activity in the Surrounding Mesenchyme Cells of the Epididymal Duct. By Angela Washington Research under the supervision of Dr. Barry T. Hinton of the Department of Cell Biology at the University of Virginia Health Systems Summer Session III 2012 Abstract It is very clear that the epididymis plays a crucial role in the maturation of spermatozoa and without a fully developed and functional epididymis male infertility will

become directly stained. In direct staining‚ the organisms must be fixed by a process such as heat. Fixing the slide prevents the organism form washing off the slide before visualization. This is accomplished by passing a smear of the bacteria through flame. The heat sets the proteins of the organism thus causing the bacteria to attach to the slide. The organism can become damaged from the setting process and the use of heat prior to staining. In indirect staining‚ the negatively charged colored portion

The specimens are manually evaluated on a 5-4-3-2-1 scale where class 5 means no shade change and class 1 means a very great shade change. An average of rating is taken as a result. Intermediate ratings like class like 3.5 or

Background: Lipid and protein composition varies in tissue types. Results: When comparing liver‚ muscle‚ and adipose tissue‚ adipose tissue had the highest percent lipid and liver tissue had the highest percent protein. Conclusion: Based on analysis of the gels‚ the liver appeared to have the most variety in proteins when comparing liver‚ muscle‚ and adipose tissue. Significance: In order to determine the composition of a tissue‚ specific macromolecules can be extracted‚ quantified‚ and analyzed

surface stains‚ where the staining substance is spilled out onto the surface or material and is trapped in the fibers‚ pores‚ indentations or other capillary structure of that surface. The material that is trapped coats the underlying material‚ and the stain reflects back light according to it’s own color. Applying paint‚ spilled food‚ and wood stains are of this nature. A secondary method of stain involves a chemical or molecular reaction between the material and the staining material. Many types

Raudah P. Mangbisa Grade VIII-Nilo VIRUS A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms‚ from animals and plants to bacteria and archaea. Characteristics: Like living organisms‚ viruses contain nucleic acids and proteins. Inside living cells‚ viruses can reproduce‚ but not by the process of mitosis like most living cells. Viruses lack some characteristics of living organisms. Outside of living cells‚ viruses are
