How can one realistically extend the blood circulation time of this particulate carrier system keeping in mind that this system should be used in patients? Both polymeric micelles and liposomes are being used as carrier systems for drugs. Human monoclonal antibodies are on the market both for therapeutic and diagnostic purposes. A hypothetical anti-leishmanial drug is strongly hydrophilic and positively charged at physiological pH. What targeting system would you recommend to develop if a fast market introduction is desirable? What is a prerequisite to use the concept of “macrophage mediated release of drugs” for therapeutic purposes? Moreover, the cost of oral therapy is generally much lower than that of parenteral therapy. Nevertheless, the oral route is not without disadvantages, particularly with respect to labile drugs such as peptide- and oligonucleotide-based pharmaceuticals. During the past two decades, numerous novel oral drug delivery systems, such as mucoadhesives, matrix systems, reservoir systems, microparticulates, and colon- specific drug delivery systems have been developed to overcome some of these limitations. It is appropriate to consider gastrointestinal structure in relation to gastrointestinal function. The function of the digestive system is to break down complex molecules, derived from ingested food, into simple ones for absorption into the blood or the lymph. This process occurs in five main phases, within defined regions of the gastrointestinal system: • ingestion (mouth); • fragmentation (mouth and stomach); • digestion (stomach and small intestine); • absorption (small and large intestine); • elimination of waste products (large intestine). There has recently been considerable interest in this site for the systemic delivery of drug moieties. The possibility of transmucosal delivery via the mucous membranes of the oral cavity is discussed in Chapter 7. The stomach The stomach is a sack that serves as a reservoir for food, where fragmentation is completed and digestion initiated. Digestion is the process by which food is progressively broken down by enzymes into molecules small enough to be absorbed; for example, ingested proteins are initially broken down into polypeptides, then further degraded into oligopeptides and finally into di- and tri-peptides and amino acids, which can be absorbed. Although the stomach does not contribute as much as the small intestine to the extent of drug 133 Figure 6. The small intestine The small intestine, comprising the duodenum, jejunum and ileum, is the principal site for the absorption of digestive products from the gastrointestinal tract. The first 25 cm of the small intestine is the duodenum, the main functions of which are to neutralize gastric acid and pepsin and to initiate further digestive processes. Digestive enzymes from the pancreas (which include trypsin, chymotrypsin, amylase and lipases) together with bile from the liver, enter the duodenum via the common bile duct at the ampulla of Vater (or hepatopancreatic ampulla). Bile contains excretory products of liver metabolism, some of which act as emulsifying agents necessary for fat digestion. The next segment of the small intestine, the jejunum, is where the major part of food absorption occurs. In addition to the great length of the small intestine, the available surface area is further enhanced by the presence of (Figure 6. The large intestine has two main functions: • to absorb water and electrolytes; • to store and eliminate fecal matter. The submucosa This is a layer of loose connective tissue that supports the epithelium and also contains blood vessels, lymphatics and nerves. The muscularis propria This consists of both an inner circular layer and an outer longitudinal layer of smooth muscle and is responsible for peristaltic contraction. The serosa This is an outer layer of connective tissue containing the major vessels and nerves. Four main types of mucosa can be identified, which can be classified according to their main function: • Protective: this is found in the oral cavity, pharynx, esophagus and anal canal. The surface epithelium is stratified squamous and may be keratinized (see Section 1.
Rosie and Doug drive to the theater together on her last two items generic valtrex 1000 mg with visa antiviral gel for herpes, but he chooses a movie playing on a different screen. Rosie’s fear of the movies had not yet reached the level of severely interfer- ing with her life. Had Rosie not dealt with her fear in this early stage, it would likely have spread from fear of movies to fear of other crowded places. Most people with fears, obsessions, or compulsions need to develop a plan with the help of a therapist. However, the example of Rosie and Doug can serve as an illustration of how a simple plan can be carried out without a therapist. Teaming Up against Anxiety One way you can help your partner overcome anxiety is to collaborate on ways to decrease stress in both your lives. With a little ingenuity, you can explore a variety of solutions that are likely to feel good to you even if you per- sonally don’t suffer from anxiety at all. For example: ✓ Take a stress management class at a local center for adult continuing education. Many of the ideas make life more fun and interesting in addition to reducing stress. It’s a great way to reduce stress, but even if you don’t have much stress, strolling under the sky together is a wonderful time to talk and is great for your health. Chapter 18: When a Family Member or Friend Suffers from Anxiety 277 ✓ Take a yoga, Pilates, or tai chi class together. Again, even if you don’t have anxiety, these classes are terrific for balance, muscle strength, flex- ibility, and overall health. You may choose to attend a church, a synagogue, or a mosque, or scope out a less traditional method of com- muning with a higher power, such as immersing yourselves in nature. Thinking about things bigger than yourselves or the mundane events of the world provides a peaceful perspective. Many people feel that such work enhances the mean- ing and purpose of their lives. And if you don’t have the time for a long vacation, go away for an occasional evening at a local hotel. Getting away from texting, telephones, e-mails, doorbells, and other endless tasks and demands, even for a night, can help rejuvenate both of you. Accepting Anxiety with Love It may seem rather counterintuitive, but accepting your loved one’s battle with anxiety is one of the most useful attitudes that you can take. In other words, whenever you discuss your loved one’s anxiety or engage in any effort to help, you need to appreciate and love all your partner’s strengths and weaknesses. If perfect people even existed, we can only imagine that they would be quite boring. Besides, studies show that people who try to be perfect more often become depressed, anxious, and distressed. You need to accept and embrace both the possibility of productive change as well as the chance that your partner may remain stuck. Accepting your partner is especially important when your efforts to help ✓ Result in an argument ✓ Seem ineffective 278 Part V: Helping Others with Anxiety ✓ Aren’t well-received by your partner ✓ Seem merely to increase your partner’s anxiety even after multiple expo- sure trials What does acceptance do? Acceptance allows you and your loved one to join together and grow closer, because acceptance avoids putting pressure on the one you care about. This message frees your loved one to ✓ Take risks ✓ Make mistakes ✓ Feel vulnerable ✓ Feel loved Change requires risk-taking, vulnerability, and mistakes. When people feel that they can safely goof up, look silly, cry, or fail miserably, they can take those risks. Giving up anxiety and fear takes tremendous courage in order to face the risks involved. Letting go of your need to see your partner change helps bol- ster the courage needed. When you take on the role of a helper, it doesn’t mean that your worth is at stake. Chapter 19 Recognizing Anxiety in Kids In This Chapter ▶ Seeing what’s making kids so scared ▶ Knowing when to worry about your kids’ anxiety ▶ Recognizing the usual anxieties of childhood ▶ Looking at the most common anxiety disorders among kids any adults can recall childhood as being a time of freedom, explora- Mtion, and fun. Not too many years ago, kids rode bikes in the street and played outside until dark. Now, anxious parents wait with their children at bus stops until they’re safely loaded.
She was switched to milk (3 glasses 2% a day) as her primary beverage besides water 500mg valtrex amex hiv infection rates victoria. She was toxic with nickel (dental metal) which would invite hordes of urinary tract bacteria, dangerously close to the ovaries. She broke out in hives from a new hair spray polluted with praseodymium which got into her ovaries. Then she called to cancel her next appointment because she was pregnant (four months from first visit). Lindy Maloy and her husband had been trying for eight years to have their second child. They wormed the dog monthly and did not want to part with it since they did not believe it mattered. They used the pet parasite program, but five months later she had higher Ascaris loads than ever. She also could not rid her uterus of intestinal fluke stages in spite of killing them with a frequency generator and using the parasite herbs. She had seven laparoscopies for endometriosis and very hard cramps with her period. The solvents in her uterus were methyl butyl ketone, acetone, carbon tetrachloride (from drinking store bought water), styrene (from drinking out of styrofoam cups), xylene (from carbonated beverages) and decane (from cholesterol-reduced foods). Her ovaries and uterus were toxic with mercury and thallium from polluted dental alloy. Christopher Gravely, a young man of 26 and Frederica, 22, promised faithfully not to get pregnant until their cleanup was complete. He was robust and healthy looking but suffered a lot from low back pain—a clue to swarms of bacteria in the lower abdomen. An electronic search of his testicles and prostate (which had been infected once) revealed iridium, platinum and yttrium. Eight months later he had completed all his tasks, his low back and pain with urination had stopped, and this encouraged him to continue with his fertility program. She, too, was started on the kidney herbs and instructed to get metal tooth fillings replaced. She was started on thioctic acid (one a day) plus zinc, (one a day), until her first missed period. After an 11 endometrial biopsy, a D&C, and laparoscopy she was diagnosed with “inadequate corpus luteum. A toxic element test showed her ovaries and uterus were full of beryllium (gasoline and coal oil), gadolinium and gallium. To reduce fossil fuel fumes in the house she removed all gas cans and the lawn mower from the attached garage. She was started on kidney herbs and promised to use con- traception until she was done. She was to drink three glasses of 2% milk a day and take a magnesium tablet and stop drinking other beverages. Three weeks later her husband canceled her appointment because she was too embarrassed and delighted to call herself. Prostate Problems If urination is not complete, so you must soon go again, es- pecially in the night, it is suggestive of pressure on the urethra from an enlarged prostate gland. Keeping a little urine from being voided is conducive to bladder and kidney infection, too, because bacteria soon find this “free food. Any supply of nickel will attract bacteria 11 A surgical procedure, called dilation and curettage, meaning di- late the bladder with air and scrape away the inner lining. To digest it, they first break the urea molecule apart into two ammonia molecules. Nickel is plentiful in the soil which is undoubtedly where these bacteria belong, breaking up and utilizing the urine and droppings left there by animals. They perform an essential task in our environment, destroying animal excrement and thereby cleaning-up the soil around us. What folly it is to load ourselves up with nickel so that in one short hop from the earth they are residing in us! If we did not supply them with nickel, as if we were just another patch of earth, they could not gain a foothold in our urinary tract and then to the prostate.
