slipped disc‚ they are often using a general term for back problems. Many people are unaware that the term ‘slipped disc’ can refer to a range of medical problems; all of which relate to the discs of soft tissue that separate the vertebrae in the spinal column. The spine is made up of 24 vertebrae‚ these vertebrae allow for a variety of movement. Flexion and extention [to bend forwards or backwards] and lateral flexion [side way movement and twisting.]. Constant combinations of the two movements can

Post-menopausal women are at risk for osteopenia because of the loss of estrogen. 6. rachischisis- fissure of the vertebral column. Rachischisis is also called spina bifida and is present at birth. 7. bunion- abnormal prominence of the joint at the base of the great toe. Having shoes that do not fit right may cause you to develop a bunion‚ especially in elderly people. 8. gout-

Lab #3: Ion Exchange Chromatography Objective The purpose of this experiment was to separate proteins on the basis of their net charge at a particular pH. In cation exchange chromatography positively charged molecules are attracted to a negatively charged column. Conversely‚ in anion exchange chromatography‚ negatively charged molecules are attracted to a positively charged column. Experimental results could be monitored in a predictable way by controlling running pH‚ salt concentration‚ and by

Chromatography: Separating Mixtures Introduction: Magic marker inks are often mixtures of several compounds. Paper chromatography is a common method of separating various components of a mixture. After separation‚ you can observe the different colors that make up a particular color of magic marker ink. You can also calculate a ratio Rf‚ which compares how far each compound traveled to how far each solvent (substance that dissolves another substance) traveled during the experiment.

compounds with lower Rf values‚ the compounds that are most polar tend to stay longer with the polar adsorbent‚ while the least polar compound travels with the eluent that is lower in polarity. 2.

Chromatography refers to a set of laboratory methods used in separating as well as purifying biomolecules. A variety of chromatography techniques exist‚ and all depend on the interaction between a stationary and a mobile state. Two types of chromatography methods were examined in this investigation. First‚ ion-exchange chromatography was used. This method separates ions and polar molecules based on their affinity to the ion exchanger [2]. Specifically‚ cation-exchange chromatography was performed
