Why is a drug’s plasma half-life important to health care providers? Half life is important in determining the frequency of a drug administered in order to maintain a continuous drug effect. Identify 2 diseases/conditions that can increase the plasma half-life of a drug. It can be prolonged when liver or kidney disease is present. What could happen if a medication with a long half-life continues to be given to a patient with one of the diseases/conditions identified in above? Patients with hepatic

Na’imat. Reg. No. : 0105514. Course: Immunology laboratory. Instructor: Dr. Muna Hassuneh. Report subject: Serum protein electrophoresis. Report No.: 1. Serum Protein Electrophoresis (SPEP) Introduction: The serum protein electrophoresis (SPEP) test measures specific proteins in the blood to help identify some diseases. And its uses an electrical field to separate the proteins in the blood serum into groups of similar size‚ shape‚ and charge. And here we’ll use gel electrophoresis which

At rest‚ a nerve cell maintains a difference in charge between the inside and the outside of the cell membrane. This difference in charge is continued by three factors. Firstly‚ in the cell membrane‚ there are sodium potassium ‘pumps’ crossing the membrane which are proteins that bring 2 potassium ions into the cell‚ for every 3 sodium ions it pumps out. As well as this‚ there are protein channels which allow potassium ions in the cell to flow out via facilitated diffusion. Potassium diffuses out

THE EFFECT OF CHEMICALS AND TEMPERATURE ON MEMBRANE DESTRUCTION AND PERMEABILITY IN BEETROOT (Beta vulgaris) Introduction The cell membrane is made up primarily of phospholipids and proteins which contribute to its selectively permeable nature. The function and permeability of the cell membrane depends on its intact structure. When destroyed‚ the permeability of the cell membrane is disrupted causing cellular contents to leak out. The cell membrane can be destroyed by physical damage‚ chemicals

It makes sense to think that quick‚ post-workout protein intake might boost recovery and promote higher performances on subsequent days of training. Indeed‚ some research has suggested that protein intake can help athletes adapt to their workouts more effectively. However‚ such studies have been flawed methodologically‚ and a new investigation reveals that combining protein with carbohydrate after workouts is not a superior strategy‚ compared with taking carbs alone. You’ve heard them: The "experts"

Darkness across Europe The Black Death‚ Crusades‚ and unequal rights were three reasons that support the idea that Europe was in a dark age from 500 to 1500 AD. The Black Death caused a lot of chaos across Eurasia‚ leaving towns empty and many died . According to Document B: Ibn al-Wardi (M)‚ "The plague began in the land of darkness.” The plague sent Europe into the shadows‚ and it took many years to recover. Another reason Europe was in a dark age was the Crusades. Stated in Document B - First

Although that I have learned the system of letting students moving across classrooms for class long before‚ I realized its problem only after attending school as an international student. As I have often heard‚ there is a prevalent that letting students moving across classrooms for different classes teaches the student to be organized and provides the students more chances to make their own course selections. However‚ in my opinion‚ due to its ineffectiveness and risks‚ the drawback of such system

nucleus and contain membrane-bounded organelles. Epithelial cells absorb and secrete‚ and the structures of a cells organelles can be viewed from an electron microscope. The nucleus – the nucleus of a cell contains most of the cell’s genetic material‚ organized as multiple long linear DNA molecules in complex with a large variety of proteins‚ such as histones‚ to form chromosomes. The nuclear envelope is a double membrane which surrounds the nucleus‚ with the outer membrane often having ribosomes

Tattoos Across Culture Derek Eades Cultural Anthropology Caitlyn Placek 07/22/2013 Tattoos Across Culture Body art and ornamentation have been a defining cultural representation for cultures since the beginning of time. In some cultures‚ such as South America‚ China and the United States‚ tattoos and piercing symbolize the physical and spiritual representation of many groups of people‚ ranging in meaning and authority. What some represent in one culture could mean the complete opposite it
