III.5 Tissue Processing for Paraffin Embedding: Each tissue was then dehydrated in ascending grades of ethyl alcohol for 15- 30 minutes each (depending on size and type of tissue) separately: 50% alcohol → 70% alcohol → 90% alcohol → absolute alcohol I & II→ Xylene I & II (clearing agent) → Xylene and Wax (1:1 ratio) ¬→ 100% wax for 1 hours at 580C (2 changes) → Embedding in wax‚ blocked‚ labeled and stored.

Germany. These men started using mammography for the diagnosis and evaluation of breast cancer. With this popularity of mammography came vast improvements with technology. Before 1969‚ many machines were not designed for imaging exclusively breast tissue. For example‚ imaging units from the past were comprised of tungsten targets‚ which were primarily used for imaging anatomy that required relatively higher doses of radiation. These units also worked off of a large focal spot which decreases the detail

CONNECTIVE TISSUE (SPECIALIZED) I. Abstract In this experiment‚ identification and classification of different types of connective tissue was performed. Also‚ cells and extracellular matrix was to be identified in them. For this‚ different already prepared slides were chosen and observed under the microscope to then identify the different parts. II. Introduction Apart from the bone and cartilage‚ the rest of the specialized connective tissues are divided into 4: Muscle tissue‚ Adipose

Effect of Temperature ( C ͦ) on Enzyme Catalase Activity in potato Aim: To investigate the Effect of temperature (10‚ 37‚ 60) Celsius (C ͦ) on enzyme catalase activity in potato using 2% of hydrogen peroxide (H202) as the substrate measuring the height (cm) of oxygen gas (bubbles) and calculating the volume of oxygen bubbles produced (cm3) Introduction: Enzymes are biological catalysts that speed up metabolic reactions without being affected. They lower the activation energy needed to start

Fetal Tissue Transplantation”‚ by Scott B. Rae. This article covers strong points such as science‚ laws‚ ethics‚ restrictions‚ and alternatives. With all the information presented in this article I find it extremely unethical to use fetuses from voluntary abortions to assist in medical care. In 1988 there was an experiment done on a 52-year-old man with Parkinson’s disease. They implanted fetal brain cells in his brain. He reported an improvement in his ability to walk and speak.
