In the kidney benicar 40mg line, it is mainly expressed in the basolateral membrane of the proximal tubules discount 40 mg benicar free shipping, and functional analysis elucidated that it accepts digoxin and T3 as substrates (111) cheap benicar 20 mg on line. Oct1 is localized to the sinusoidal membrane of the hepatocytes surrounding the central vein and basolateral mem- brane in the kidney (115 40mg benicar with amex,116) purchase 10mg benicar fast delivery. Com- parison of substrate recognition between Oct1 and Oct2 was performed using a þ gene expression system. There was no difference in the transport activities of cimetidine, ranitidine, and famotidine by Oct1, while Oct2 efficiently transports cimetidine rather than ranitidine and famotidine (120). Oct3 is ubiquitously expressed in normal tissue with low level, and, among them, gonads (testes and ovaries), placenta, and uterus exhibited relatively high expression (119). Oat1 is predom- inantly expressed in the kidney, where it is localized in basolateral membrane of the proximal tubules (130). The kidney expression is markedly higher in female rats than in male rats with similar hepatic expression (136,137), whereas the hepatic expression exhibits gender difference in mice, high in female and almost absent in male (138), although a controversial result was also obtained (139). Functional analyses of Oat2 elucidated that it exhibits substrate specificity similar to Oat1 (141), and accepts nonsteroidal anti-inflammatory drugs, such as salicylate, ketoprofen, and indomethacin as substrate (141–143). Oat2 has been suggested to be involved in the uptake of indomethacin and ketoprofen by rat hepatocytes (142,143). Rat Oat3 is expressed in the kidney, liver, eye, and brain (144), while its human counterpart is detected predominantly in the kidney (145,146). In rat brain, Oat3 is expressed in brain capillaries and choroid plexus, where it is localized on the abluminal and brush border membranes of the brain capillaries and choroid plexus epithelial cells, respectively, and accounts for the uptake of hydrophilic organic anions (81,147–150). In addition, it accepts some cationic compounds, cimetidine, ranitidine, and famoti- dine (144,150), which have been known as bisubstrate and recognized by both organic anion and cation transporters (153). Using rat kidney slices, it has been suggested that Oat3 is responsible for the uptake of amphipathic organic anions, such as pravastatin, and steroid conjugated with sulfate (24,53,151). Since the transport characteristics seem to be consistent with the previous observation using brush border membrane vesicles, it has been considered to be expressed on the brush border membrane of the kidney. Octn2 is hereditarily deficient in a mouse strain, jvs mice, which exhibits the similar symptoms of systemic carnitine deficiency (165). Valinyl esterification of the antiviral agent acyclovir showed a three- to fivefold increase in bioavailability (174–176). This uptake does not depend on Na and H , but on Cl (190), and increasing extracellular concentration of chloride reduced the uptake of benzyl- penicillin (190). The substrates include faropenem, foscarnet, and mevalonate, as well as benzylpenicillin (190). In contrast to the kidney, the expression is localized to the sinusoidal membrane of the liver (190). When the direction of the – concentration gradient of Cl is taken into consideration, the transport direction mediated by NaPi-1 is efflux from inside the cells to the blood and urine in the liver and kidney, respectively. P-gp P-gp was originally found as overexpressed protein on the plasma membrane of multidrug-resistant tumor cells, and confers multidrug resistance by actively extruding anticancer drugs to the outside (191,192). In normal tissue, P-gp is 164 Kusuhara and Sugiyama expressed in the clearance organs (liver and kidney), the site of absorption (small and large intestine), and tissue barriers (brain capillary endothelial cells), where it is localized to the luminal side, i. In the small intestine and brain capillaries, Mdr1a is the predominant isoform, while both isoforms are expressed in the liver and kidney (200). P-gp expression exhibits regional difference; it increases from the duodenum to the colon, both in rodent (201–203) and human (204–206). This expression pattern is associated with functional activity, namely, lowest activity in the duodenum and highest in the ileum (202) and colon (203). The substrate specificity of P-gp is quite broad, and a number of com- pounds have been identified as P-gp substrates, generally overall positive charge or neutral compounds (193–199,207). The tissue distribution and membrane localization suggest that P-gp limits oral absorption and penetration into the brain and mediates biliary and urinary excretion of drugs. This has been sup- ported by an in vivo finding using Mdr1a(–/–) and Mdr1a/1b(–/–) mice. The biliary excretion clearance and intestinal excretion clearance of tri-n-butylme- thylammonium, azidoprocainamide methoiodide and vecuronium was decreased in Mdr1a(–/–) mice, and the renal clearance of tri-n-butylmethylammonium and azidoprocainamide methoiodide was also decreased in Mdr1a(–/–)(208). For digoxin, the amount excreted into the intestine fell markedly, while that into the bile and urine was unchanged in Mdr1a(–/–) mice (209), but fell to half the normal value in the Mdr1a/1b(–/–) (210). Following oral administration, the plasma concentration of ivermectin (200), paclitaxel (211), and fexofenadine (212) was greater in Mdr1a(–/–) mice. In situ intestinal perfusion study elucidated that the outflow concentrations of quinidine, ritonavir, cyclosporin A, dauno- mycin, loperamide, and verapamil (for some time points) was decreased in Mdr1a/1b(–/–) mice, indicating that the intestinal absorption of these drugs is limited by P-gp.

Work with your health care team to keep your feet, eyes, heart, and teeth healthy. The former are proverbs used for medical purposes even though they may have no medical content. The perception of a proverb as medical in content is flexible, varying from collection to collection. In thematic proverb collections the items are usually taken out of the context but their very inclusion is in itself a context-specifying factor. A new definition of applied folklore is proposed, stressing the role of non-folklorists. The wish to use prov- erbs for concrete purposes inheres in the material itself as much as the wish to reveal its universal formulas. He informed his readers that he was publishing it after becoming disillusioned with the topic, which initially had been designed for his doctoral dissertation (Krikmann 2001: 11). This confession encourages me to open this article, which is intended for publication in this journal’s issue hon- ouring Prof. My interest in medical proverbs began in my early student years, when my father, a physi- cian, suggested this topic to me as a joint venture. For two years we searched for medical proverbs in various collections, discussing the criteria for the no- tion “medical” and for the classification of our material. Concurrently with our joint collecting activities I completed my seminar paper and even published a short paper, which I do not include in my list of publications. At that point I began to harbour misgivings as to the scientific value of the topic, and I took the opportunity to discuss them with two venerable literary scholars, Miron Petrovskii and Vadim Skuratovskii. Their verdict was unanimous: although the collection was interesting and the seminar work showed a student’s ability in research, the topic itself had no philological value. Both the collection and Folklore 46Folklore 46Folklore 46Folklore 46Folklore 46 http://www. Although presented to me very politely and amiably, this conclusion caused me a profound psychological trauma. For six months I could write nothing at all, and then I switched abruptly from folklore to literary studies. My emigra- tion in 1991 caused me to return to the path of folklore studies, but one angle of it, namely medical proverbs, remained previously sealed for me and thus my father must be again mentioned. He carried our collection in his immi- grant luggage; he even brought along my old seminar paper. For thirty years he tried to persuade me to publish our collection, occasionally encountering “explosions” from myself. He refused to publish it under his own name, al- though I ardently suggested that he do so and while I said “never”, he still waited patiently. Then, suddenly, the situation changed when two years ago, in one of our numerous fervent debates on medical proverbs it struck me that my father was growing old. This understanding changed the whole perspective of the issue so I was not about to deprive him of one of the few pleasures remain- ing to him.

order 40mg benicar visa

There is no curative therapy against rhinoviruses 20 mg benicar amex, but the symptoms can be relieved until the illness runs its course order benicar 10 mg visa. A variety of antihistamines are available and most are used in combination with a sym- pathomimetic amine order benicar 10mg fast delivery, such as pseudoephedrine with its decongestant activity benicar 10mg without prescription. Intranasal routes of administration are equally benicar 20mg low price, if not more, effective than oral administration. Importantly, the nasal route reduces dose delivered to the fetus while adequately treating the patient’s symptoms (Hornby and Abrahams, 1996). Pseudoephedrine Pseudoephedrine hydrochloride is the preferred agent for pregnant women who require a decongestant (Hornby and Abrahams, 1996). It is the most frequently used sympath- omimetic and is usually taken as a decongestant. It is also frequently combined with dif- ferent antihistamines in ‘common cold’ or ‘sinus’ medications. Epidemiological studies of more than 1000 first-trimester human pregnancies exposed to pseudoephedrine indi- cate no association with congenital anomalies (Aselton et al. Ephedrine (Ephedra, Ma Huang, over-the-counter weight loss/energy pill) used in large doses is associated with sudden cardiac death in adults, and based upon anecdotal information should be avoided during pregnancy because of potential adverse maternal and fetal effects, including tachycardia and serious adverse cardiovascular events, such as heart attack, stroke, and fetal vascular disruption. Phenylephrine and phenylpropranolamine Phenylephrine and phenylpropranolamine are decongestants in common use and are frequently combined with antihistamines in cold and flu remedies. According to their manufacturer, these agents may interfere with uterine blood flow and thus should be used with caution in women with conditions already associated with decreased uterine blood flow, such as hypertension. A weak, possible association of phenylephrine and phenylpropra- nolamine with congenital anomalies was found in the Collaborative Perinatal Project among 1249 and 726 pregnancies, respectively (Heinonen et al. It is unlikely that either agent is causally related to congenital malformations in first-trimester- exposed fetuses. In another study of more than 225 infants exposed during the first trimester, no such association was found (Aselton et al. No adverse effects were found among offspring in animal studies regarding the teratogenicity of these two agents. The fre- quency of congenital anomalies was not increased among more than 250 infants whose mothers took oxymetazoline during the first trimester (Aselton et al. Similarly, among 432 infants whose mothers took xylometazoline in the first trimester, the frequency of congenital anomalies was not increased (Aselton et al. Most of these studies were controlled and only the numbers of exposed are shown here for illustrative purposes without odds ratios and comparative data. These medications act primarily by competing with histamine for H -receptor binding. Other effects of some members of this group include sedation, antiemesis, antimotion sickness, and antidyskinesia. The primary difference between the first-generation and second-generation antihista- mines is the sedative effect. Second-generation antihistamines are also referred to as the nonsedating antihistamines. Adapted from a recent review, the percentage of congenital anomalies shows the generally accepted nonteratogenic nature of antihistamines in human exposure (Gilbert et al. Most authorities consider antihistamines to be safe for use during pregnancy, but it is prudent to rely on research for specific agents rather than blanket statements about drug classes. One report suggested that antihistamines as a group may be associated with an increased fre- quency of retrolental fibroplasia in premature infants (Zierler and Purohit, 1986). Propylamine derivatives Propylamine derivatives include brompheniramine, chlorpheniramine, dexchlorpheni- ramine, and triprolidine. Of all antihistamines analyzed in the Collaborative Perinatal 210 Antihistamines, decongestants, and expectorants during pregnancy Project, only brompheniramine was found to be weakly associated with congenital defects in 65 offspring, and it is unlikely that it was causative (Heinonen et al. In a larger study of 270 infants born following first-trimester exposure to brompheniramine, there was no increased frequency of congenital anomalies (Aselton et al. Meta-analysis of all available data on brompheniramine indicate it is not a human teratogen (Seto et al. Chlorpheniramine was not associated with an increased frequency of congenital anom- alies; neither was the closely related agent dexchlorpheniramine (Gilbert et al.

purchase 40 mg benicar visa

There will be many chemical reactions between the substance and the water to produce a number of test substances all contained in one bottle benicar 40mg otc. Within the body discount benicar 40mg with visa, where salt and water are abundant cheap benicar 40 mg fast delivery, similar reactions may occur between elements and water buy 40 mg benicar mastercard. Since the electronic properties of elemental copper are not the same as for copper compounds cheap 20mg benicar with mastercard, we would miss many test results if we used only dry elemental copper as a test substance. For instance, a tire balancer made of lead can be easily obtained at an auto service station. If you have searched your kidneys for leaded gasoline, fishing weights and tire balancers and all 3 are resonant with your kidneys, you may infer that you have lead in your kidneys since the common element in all 3 items is lead. The biggest repository of all toxic substances is the grocery store and your own home. You can make test substances out of your hand soap, water softener salt, and laundry detergent by putting a small amount (1/16 tsp. Check the items in Toxic Elements (see The Tests) to see where they are commonly found. For instance, arsenic is in car- pets, stuffed furniture and wallpaper, originating in the pesti- cide put there. Here are some suggestions for finding sources of toxic products to make your own toxic element test. If the product is a solid, place a small amount in a plastic bag and add a tablespoon of filtered water to get a temporary test product. If the product is a liquid, pour a few drops into a glass bottle and add about 2 tsp. Small amber glass dropper bottles can be purchased by the dozen at drug stores (also see Sources). Copper: ask your hardware clerk to cut a small fragment off a copper pipe of the purest variety or a ¼ inch of pure copper wire. Gold: ask a jeweler for a crumb of the purest gold available or use a wedding ring. Mercury: a mercury thermometer (there is no need to break it), piece of amalgam tooth filling. Patulin (apple mold): cut a sliver of bruised apple that has turned brown, wash and peel first to avoid the benzene in the spray that may be on the peel. Propyl alcohol: (actually, isopropyl alcohol, not n-propyl alcohol) rubbing alcohol from pharmacy. Radon: leave a glass jar with an inch of filtered water in it standing open in a basement that tested positive to radon using a kit. Zearalenone: combine leftover crumbs of three kinds of corn chips and three kinds of popcorn. Since few of these specimens are pure, there is a degree of logic that you must ap- ply in most cases. If you are testing for barium in your breast, a positive result would mean that a barium-containing lip stick tests positive and a barium-free lip stick is negative. A chemistry set for hobbyists is a wonderful addition to your collection of test specimens. This does not mean there is no silver present in your body; it only means there is no silver chloride present in the tissue you tested. The most fruitful kind of testing is, probably, the use of household products themselves as test substances. The soaps, colognes, mouthwash, toothpaste, shampoo, cosmetics, breads, dairy products, juices and cereals can all be made into test specimens. Also prepare samples of the soap, shampoo, shaving cream and other products you last put on your body. Method: Listen for resonance between your white blood cells and the daily foods and products you use. Making Organ Specimens To test for toxic elements or parasites in a particular organ such as the liver or skin, you will need either a fresh or frozen sample of the organ or a prepared microscope slide of this or- gan. Meat purchased from a grocery store, fresh or frozen, pro- vides you with a variety of organ specimens. To make a du- rable unfrozen sample, cut a small piece, the size of a pea, and place it in an amber glass bottle (½ oz. Pork brains from the grocery store may be dissected to give you the different parts of the brain.
