The situation is similar for virtually every other biophar- maceutical discount 4mg singulair visa asthma control step 0, particularly since these molecules occur in animals in vanishingly small amounts or purchase 10mg singulair fast delivery asthma treatment ventilator,as in the case of therapeutic an- tibodies buy singulair online asthmatic bronchitis deaths, do not occur naturally in animals at all. Most biopharmaceuticals are therefore produced in cultures of microorganisms or mammalian cells. Simple proteins can be 30 Little helpers: the biological production of drugs The bacterium Escherichia coli is relatively easy to cultivate. For complicated substances consisting of several proteins or for substances that have to be modified by the addition of non-protein groups such as sugar chains, mam- malian cells are used. To obtain products that are identical to their human equivalents, the appropriate human genes must be inserted into the cultured cells. These genetically manipulated cells then contain the enzymes needed to ensure correct folding and processing of the proteins (especially in the case of mam- malian cells) as well as the genetic instructions for synthesising the desired product. In this way a genetically modified cell is obtained which produces large quan- tities of the desired product in its active form. Biotech production: each But multiplying these cells poses a technological facility is unique challenge, particularly when mammalian cells are used to produce a therapeutic protein. Cells are living organisms, and they react sensitively to even tiny changes in their environment. From the nutrient solution to the equip- ment, virtually every object and substance the cells touch on their way from, say, the refrigerator to the centrifuge can affect them. Drugs from the fermenter 31 High-tech cell cultivation: biotechnological production facility in Penzberg Large-scale industrial production facilities for biopharma- smallest impurity can render a batch useless. These factors determine not only the yield of useful product but also the quantity of interfering or undesired byproducts and the structure of the product itself. As a result, each biopharmaceu- tical production plant is essentially unique: Changing just one of hundreds of components can affect the result. Focus on Chinese Laboratories and manufacturers around the hamster cells world work with standard cell lines to produce biopharmaceuticals, enzymes and antibodies. These cell lines are used because they are well researched and, as far as is possible with living organisms, are amenable to stan- dardisation. Biotech researchers insert structural and control genes into the cells of these and similar lines to produce the desired pharma- ceutical. This establishes a new cell line, which is usually treated as a closely guarded company secret. After all, these cells are the actual factories of the biopharmaceutical concerned. They are allowed to reproduce and are then safely stored at low tempera- tures in what is known as a master cell bank. If the cells need to 32 be stored for long periods, they can be kept almost indefinitely in liquid nitrogen at 196C. Cells are then drawn from the cell banks and used in biophar- maceutical production. Broadly speaking, the production pro- cess is divided into the following steps: Cultivation: The cells are transferred from the cryogenic cell bank to a liquid nutrient medium, where they are allowed to reproduce. The cells secrete the desired product, ent solution is inoculated with cells from a cell bank. These which is then isolated from the solution, purified and trans- are allowed to reproduce in stages up to a scale of several ferred to containers. During the growth phase the cell culture is transferred to progressively larger culture vessels. Fermentation: The actual production of the biopharmaceutical occurs during this phase. The culture medium contains sub- stances needed for the synthesis of the desired therapeutic protein. In total, the medium contains around 80 different constituents at this stage, although manufacturers never dis- close the exact composition. The industrial-scale steel vessels in which fermentation takes place have capacities of 10,000 liters or more. There are not only technological but also bio- logical constraints on the size of the reactor vessel: The big- ger a fermenter is, the more difficult it becomes to create uni- form conditions around all the cells within it. Purification: In technical terms, the production of biopharma- ceuticals in cells is a one-step process and the product can be purified immediately after fermentation. In the simplest case the cultured cells will have secreted the product into the am- bient solution. If, on the other hand, the product remains in the cells follow- ing biosynthesis, the cells are first isolated and digested (i. Theyield frombioproduction processes isusually much lower than from chemical synthesis. For example, a 10,000-liter fermenter yields only a few kilograms of a therapeutic anti- body such as MabThera/Rituxan (rituximab) or Herceptin (trastuzumab). Several more weeks are then needed to test the product: Each product batch is tested for purity to avoid quality fluctuations, and a 99. Formulation: The final steps in the production of biopharma- ceuticals are also demanding. The sensitive proteins are con- verted to a stable pharmaceutical form and must be safely packaged, stored, transported and finally administered. Throughout all these steps the structural integrity of the molecule has to be safeguarded to maintain efficacy. At pres- 34 ent this is only possible in special solutions in which the product can be cryogenically frozen and preserved, though the need for low temperatures does not exactly facilitate transport and delivery. Biopharmaceuticals are therefore produced strictly on the basis of demand even more so than traditional drugs. Because of the sensitive nature of most biopharmaceuticals, their dosage forms are limited to injectable solutions. Thera- peutic proteins cannot pass the acidic milieu of the stomach undamaged, nor are they absorbed intact through the in- testinal wall. Though work on alternatives such as inhalers is in progress (especially for the relatively stable insulin mol- ecule), injection remains the only option for introducing biopharmaceuticals into the body. Nowadays all the steps in the production of biopharmaceuticals are fully automated. Because cell cultures react so sensitively to fluctuations in ambient conditions, the window for high-yield production is quite narrow: If the physical and chemical properties of the nu- trient medium deviate ever so slightly from the norm, the pro- duction staff must take action to restore optimum conditions. Even trace amounts of impurities can spell considerable economic loss, as the entire production batch then has to be dis- carded and the production process has to be restarted from scratch with the cultivation of new cells. Advantages in terms of Despite their elaborate production process, bio- efficacy and safety pharmaceuticals offer a number of advantages, two of which are uppermost in patients minds: efficacy and safety. Thanks to their structure, proteins have a strong affinity for a specific target molecule. Unlike traditional, low-molecular- weight drugs, biopharmaceuticals therefore rarely enter into nonspecific reactions. The result is that interference and danger- ous interactions with other drugs as well as side effects are rare.
Physical activity has been shown to be associated with decreased symptoms of depression and anxiety buy singulair 10 mg fast delivery asthma treatment mask. Physical activity has been consistently shown to be associated with improved physical health generic singulair 5 mg visa asthma treatment drug types, life satisfaction order singulair 4 mg mastercard asthmatic bronchitis complications, cognitive functioning, and psychological well-being. Conversely, physical inactivity appears to be associated with the develop- ment of psychological disorders. Exercise compares favorably to antidepressant medications as a first-line treatment for mild to moderate depression and has also been shown to improve depressive symptoms when used as an adjunct to medications. While not as extensively studied, exercise has been shown to be an effective and cost-efficient treatment alternative for a variety of anxiety disorders. While effective, exercise has not been shown to reduce anxiety to the level achieved by psychopharmaceuticals. Depression is the leading cause of disability worldwide and is predicted to be the second largest contributor to the global burden of disease by the year 2020 . More than 30 million Americans have a lifetime history of anxiety, and anxiety disorders cost an estimated $42 billion per year in the United States [9, 10]. The most common types of anxiety disorders are generalized anxiety disorder, panic disorder, social anxiety disorder, and posttraumatic stress disorder [11-15]. Although options for pharmacologic treatment have expanded significantly in the past 20 years, between one- and two-thirds of patients will not respond to the first antidepressant prescribed, and 15 to 33% will not respond to multiple interventions [16-18]. Additionally, anxiolytic and antidepressant medications are expensive and associated with a number of serious and quality of life altering side effects. Physical activity and exercise have been recommended for the prevention and treatment of numerous diseases and medical conditions (see Table 1). Most notably, habitual physical activity prevents the development of coronary artery disease and reduces symptoms in patients with established cardiovascular disease . Evidence also supports the role of exercise in reducing the risk of other chronic diseases such as type 2 diabetes mellitus, osteoporosis, obesity, and cancer of the breast and colon. In addition, exercise and physical activity have been recommended for the treatment of depression and anxiety. Definition of Physical Activity and Exercise Physical Activity Bodily movement produced by skeletal muscles that results in energy expenditure beyond resting level. Exercise Subset of physical activity that is planned, structured, repetitive, and purposeful. Subsequently, physical activity has been shown to be associated with decreased symptoms of depression and anxiety in numerous studies [22-25]. For example, in a nationally representative sample of adults ages 1554 in the United States (n = 8,098), regular physical activity was associated with a significantly decreased prevalence of current major depression and anxiety disorders . Physical activity was not found to be significantly associated with other affective, sub- stance use, or psychotic disorders. Habitual exercise correlates to a heightened level of mental health and well- being and reduced feelings of anxiety regardless of the gender of the indi- vidual. In a group of men (n = 5,451) and women (n = 1,277), relative increases in maximal cardiorespiratory fitness and habitual physical activity are associated with lower depressive symptoms and greater emotional well-being . Ohta  noted that 30 minutes or more of walking or cycling while commuting to work may be associated with an increased perception of mental health in men. In contrast to gender, the age of the individual may affect the relationship between physical activity and mental health. Exercise has a very small but statistically insignificant effect on reducing anxiety in adolescents [31, 32]. In contrast, Fox  found that a population of European adults over the age of 70 had perceived levels of health and quality of life that were positively correlated to higher levels of physical activity. While regular physical activity appears to be related to mental well-being, physical inactivity appears to be associated with the development of psycho- logical disorders. Some cross-sectional and prospective-longitudinal clinical and epidemiological studies have shown a direct relationship between physical inactivity and symptoms of depression and anxiety . Most con- sistently associated with depression are the findings of volume loss in the hippo- campal formation [36-38]. As noted above, imaging studies have shown that depressed patients have decreased hippocampal volume . Ernst and colleagues  hypothesize that exercise similarly decreases depressive symptoms by increasing brain neurogenesis. Other possible mechanisms for exercises ability to improve mood include the association with exercise and increased levels of endocannabinoids, which are associated with analgesia, anxiolysis, and a sense of well-being . Finally, exercise improves self-concept in depressed patients, possibly leading to decreased depressive symptoms . The National Guideline Clearinghouse states in a consensus-based recommendation that exercise is recommended as an adjunctive treatment to antidepressants or psychotherapy . Multiple studies exist that suggest that exercise is an effective treatment for depression. A Cochrane meta-analysis of 25 randomized controlled trials com- paring exercise and placebo or a control intervention found that the exercise groups had a significant improvement in depressive symptoms when compared to the placebo or control group . Only three trials with sufficient allocation concealment, intention to treat analysis, and blinded outcome assessment were found (see Table 2). When these three trials were analyzed together, the effect size was not significant. Blumenthal  conducted a randomized controlled trial in which they assigned 156 adults over age 50 to either aerobic exercise, sertraline, or both. After 4 months, all three groups had a statistically significant improvement in their depressive symptoms with no statistically sig- nificant difference between the groups. The medication group did have a faster response to treatment in the first 4 weeks. The differences between the intervention and placebo groups were not statistically different. Exercise has also been shown to improve depressive symptoms when used as an adjunct to medications. Exercise significantly improved symptoms when added to an antidepressant in a group of older patients with depression that had not responded to 6 weeks of antidepressant medication alone . Unlike its benefit as an adjunct to antidepressive medications, exercise in addition to cog- nitive therapy was found to be no better than either alone . A dose-response effect with exercise in the treatment for depression has been noted. In one study, high intensity weight training was more effective than low intensity weight training in treating depression . Low intensity weight training and general practitioner care were found to have nearly the same improvement in depression that is consistent with the widely accepted number of the 30% placebo effect in depression treatment. With aerobic exercise, intensity equaling the energy expenditure in public health recommendations was more effective than a program of guided movements of low intensity that had a reduction in depressive symptoms equal to the placebo group . While more research is needed on the type of exercise needed for depression treatment, available research indicates that the type of exercise is not as impor- tant as having the physical activity reach a sufficient intensity. For example, both running and weight lifting were found to significantly decrease depressive symptoms with no significant difference found between these two forms of physical activity and the decrease in symptoms .
