Often enzymatically digested plant extracts are used as supplements to improve the growth-promoting quality of serum-free media (131) buy isoptin 120 mg free shipping. These growth media are generally considered safe and are relatively inexpensive (approximately $1/L) when produced in large scale discount isoptin 40mg fast delivery. Compounding of media is usually done by specialized companies that also certify the quality. Once the cloned cells are adapted to a certain medium, an extensive program of sta- bility testing is necessary to ensure that the cells are expressing the antibody in con- sistent quality and quantity over a certain number of passages. The number of passages in stability testing depends on the final production scale envisaged. If we assume that X cell passages are needed to reach the final production harvest, extension of stability testing to approximately 1. It is therefore also recommended to perform the adaptation and stability test- ing of the cloned cells in a bioreactor that most closely simulates the physical environment of the bioreactor that will be used for the manufacturing process. The characterization includes a series of investigations that establish and define cell identity and safety in a clearly traceable and reproducible manner. These cells and the manufac- turing process define the final drug with respect to all its characteristics (132). In addi- tion, various quality control tests are conducted on each batch of the biologic drug before 88 Kunert and Katinger Fig. Manufacturing consistency must be proved in so-called consecutive lots, and changes in the established manufacturing process are only allowed under strict change control, validation, and approval by the licensing authority (depend- ing on the status of the drug and the nature of the change). Production in a Bioreactor A great variety of devices for in vitro cultivation of animal cells have been devel- oped. Some common characteristics of animal cells that determine the design of in vitro cultivation systems (i. However, if production units for manufacturing several hundred kilogram quantities per year are necessary, most of the currently used small-scale pro- duction devices are no longer useful. Only a few bioreactor configurations are applic- able to large-scale, mass cell propagation and biologic manufacture. If the suspension type of cell culture is used for production, both the stirred tank reactor, the air lift reac- tor, and the packed bed reactor (133) can be used for large scale. If the adherent type of cell culture is necessary, the fluidized bed reactor is a good choice (134). If the stirred tank reactor is used for animal cells, axial flow impellers with large blades are preferable, as they lead to good mixing with low mechanical shear forces. Both reactor types (the airlift and the stirred tank reactors) have been used for up to 10,000-L working volume in animal cell suspension culture. Although the airlift reactor performance is optimal, with a constant filling volume slight modifications of the inner draft tube also allow its use with variable filling for batch-fed culture (135). In batch culture the aver- 6 age cell densities are in the range of 14 10 cells/mL, whereas batch-fed culture allows a slight increase in cell density and maintenance in a productive state for longer time. The batch-fed culture is defined by the increase of osmolarity due to the feed of substrates and by the accumulation of metabolites such as lactate and ammonia (136,137). On the basis of ultrafiltration principles, devices have been developed that give the reac- tor a kind of kidney function to remove low-molecular-weight metabolites and ammonia, while the large biomolecules are retained. Thus cell viability and density are improved and the yield of product is increased. Other possibilities to increase productivity are found with devices that allow continous perfusion with fresh media and cell retention in the reactor. Various unit operations such as ultrasonic devices (138), special filters (139), cartrifuges, or backlooping of cells into the reactor can increase cell retention. Such high-density con- 8 tinuous perfused systems can accumulate cell densities beyond 10 cells/mL (140). Depending on the expression rate of the production cells and the cultivation methods applied, antibody titers above 1 g/L crude culture harvest can be accumulated. Downstream Processing and Purification Antibodies are applied therapeutically in high doses and at high concentrations. The process steps downstream from the bioreactor must therefore establish a product of the highest possible purity. Furthermore, the single process steps must allow safe sanitiza- tion procedures since downstream processing usually cannot be performed under ster- ile conditions. In addition to the purification of the antibody from impurities contained in the matrix of the culture supernatant, the downstream process steps have to be designed and validated to remove and inactivate potential viral contaminations. A typical downstream processing procedure usually starts with removal of the cells and cell debris from the crude culture supernatant. Cell sedimentation combined with filtration or centrifugation are generally applied. The following process steps usually 90 Kunert and Katinger include a series of chromatographic columns containing different matrices, each of which contribute complementary separation principles to the entire purification process.

Suggest that they write down when they take their medicines or that they use a pill box container labeled to show the days and the times of the day. This page left intentionally blank Heart Failure 4 Objectives By the end of this session, community health workers will be able to Explain the cause of heart failure. In fact, its one of the most common reasons people 65 and older go into the hospital. It does mean the heart is not working well, but a person can live for many years with this condition. You can help people in your community know the signs of heart failure and what to do about them. Talking Points: Remember that we talked about how the heart works in the last session? When a person has heart failure the heart does not pump blood as well as it should. Blood moves more slowly through the body and less oxygen and nutrients reach the body and the brain. Everyday activities such as walking, climbing stairs or carrying groceries can become harder. Also, when the heart pumps blood more slowly the blood can back up into the blood vessels around the lungs and leak into the lungs. People with heart failure can develop swelling in the feet, ankles, legs, or stomach and can suddenly gain weight. Talking Points: Heart failure can have many causes, but the most common causes are Narrowing or blockage of the vessels that supply blood to the heart muscle (coronary artery disease). Talking Points: If people have heart failure, chances are they have already made a trip to the emergency room, or at least spent some time in the hospital. They can decrease the chances of another hospital stay by calling their doctors right away if any of these warning signs appear Increased swelling of feet, ankles, legs, and abdomen (stomach). Talking Points: The doctor will ask about your medical history and does a physical exam (listen to your heart and lungs, weigh you, and take your blood pressure). The doctor may want to do some of the following tests Chest X-ray to see the condition of the heart (normal or enlarged) and lungs (congestion). Treatment can keep people feeling good and leading productive lives, often for many years. To treat heart failure, a doctor usually prescribes medicine and will recommend rest. Its important that people take medicines the way their doctor or nurse advises them. Also, people need to weigh themselves every day to see if they are holding onto extra fuid in their bodies. There are medicines that can treat mild or moderate heart failure, but in severe cases surgery might be needed, or even a heart transplant. Taking Medicine for Heart Failure Talking Points: Doctors usually prescribe one or more medicines to treat heart failure. Sometimes one medicine is given at frst and others may be added later on, or two or more medicines may be given at the start. Its easy to become confused about when to take medicines if a person needs to take several medicines at different times during the day. Fill the pillbox at the beginning of the week and open each days section to take your pills for that day. Or use a phone app to remind you Remember to get your prescriptions reflled on time! Diet, Fluids, and Weight Gain Talking Points: Diet High sodium intake is a major problem in the U. On average, American adults eat more than double the recommended limit for most adults. The Dietary Guidelines for Americans, 2010 recommends that Americans aged 2 and up reduce sodium intake to less than 2,300 mg per day (about 1 teaspoon total from all food).
