Flagellate EUKARYOTES, found mainly in the oceans. They are characterized by the presence of transverse and longitudinal flagella which propel the organisms in a rotating manner through the water. Dinoflagellida were formerly members of the class Phytomastigophorea under the old five kingdom paradigm.
An island in the Greater Antilles in the West Indies. Its capital is San Juan. It is a self-governing commonwealth in union with the United States. It was discovered by Columbus in 1493 but no colonization was attempted until 1508. It belonged to Spain until ceded to the United States in 1898. It became a commonwealth with autonomy in internal affairs in 1952. Columbus named the island San Juan for St. John's Day, the Monday he arrived, and the bay Puerto Rico, rich harbor. The island became Puerto Rico officially in 1932. (From Webster's New Geographical Dictionary, 1988, p987 & Room, Brewer's Dictionary of Names, 1992, p436)

Evaluation of the chronic toxicity and oncogenicity of N,N-diethyl-m-toluamide (DEET). (1/74)

Chronic toxicity and/or oncogenicity studies were conducted in rats, mice, and dogs with the insect repellent DEET. DEET was mixed in the diet and administered to CD rats for two years at concentrations that corresponded to dosage levels of 10, 30 or 100 mg/kg/day for males and 30, 100, or 400 mg/kg/day for females; to CD-1 mice for 18 months at dosage levels of 250, 500, or 1000 mg/kg/day; and to dogs for one year, via gelatin capsules, at dosage levels of 30, 100, or 400 mg/kg/day. In the rodent studies, each group consisted of 60 animals of each sex, and two concurrent independent control groups, each containing 60 animals/sex were included in each study. Each group in the dog study consisted of four male and four female dogs and one control group was included in the study. Treatment-related effects were observed at the highest dose level in all three studies. For rats, the effects included decreases in body weight and food consumption and an increase in serum cholesterol in females only. In mice, the effects observed were decreases in body weight and food consumption in both sexes. The effects observed in dogs included increased incidences of emesis and ptyalism, and levels of transient reduction in hemoglobin and hematocrit, increased alkaline phosphatase (males only), decreased cholesterol, and increased potassium. One male dog in the high-dose group also exhibited ataxia, tremors, abnormal head movements, and/or convulsions on several occasions during the study. The highest no-observed-effect levels (NO-ELs) for rats, mice and dogs were determined to be 100, 500, and 100 mg/kg/day, respectively. No specific target organ toxicity or oncogenicity was observed in any of the studies.  (+info)

Nuclear factor-kappaB plays an essential role in the late phase of ischemic preconditioning in conscious rabbits. (3/74)

Although it is recognized that late preconditioning (PC) results from upregulation of cardioprotective genes, the specific transcription factor(s) that govern this genetic adaptation remains unknown. The aim of this study was to test the hypothesis that the development of late PC is mediated by nuclear factor-kappaB (NF-kappaB) and to elucidate the mechanisms that control the activation of NF-kappaB after an ischemic stimulus in vivo. A total of 152 chronically instrumented, conscious rabbits were used. A sequence of six 4-minute coronary occlusion/4-minute reperfusion cycles, which elicits late PC, induced rapid activation of NF-kappaB, as evidenced by a marked increase in p65 content (+164%; Western immunoblotting) and NF-kappaB DNA binding activity (+306%; electrophoretic mobility shift assay) in nuclear extracts isolated 30 minutes after the last reperfusion. These changes were attenuated 2 hours after ischemic PC and resolved by 4 hours. Competition and supershift assays confirmed the specificity of the NF-kappaB DNA complex signals. The mobility of the NF-kappaB DNA complex was shifted by anti-p65 and anti-p50 antibodies but not by anti-c-Rel antibodies, indicating that the subunits of NF-kappaB involved in gene activation after ischemic PC consist of p65-p50 heterodimers. Pretreatment with the NF-kappaB inhibitor diethyldithiocarbamate (DDTC; 150 mg/kg IP 15 minutes before ischemic PC) completely blocked the nuclear translocation and increased DNA binding activity of NF-kappaB. The same dose of DDTC completely blocked the cardioprotective effects of late PC against both myocardial stunning and myocardial infarction, indicating that NF-kappaB activation is essential for the development of this phenomenon in vivo. The ischemic PC-induced activation of NF-kappaB was also blocked by pretreatment with Nomega-nitro-L-arginine (L-NA), a nitric oxide synthase (NOS) inhibitor, N-2-mercaptopropionyl glycine (MPG), a reactive oxygen species (ROS) scavenger, chelerythrine, a protein kinase C (PKC) inhibitor, and lavendustin A, a tyrosine kinase inhibitor (all given at doses previously shown to block late PC), indicating that ischemic PC activates NF-kappaB via formation of NO and ROS and activation of PKC- and tyrosine kinase-dependent signaling pathways. A subcellular redistribution and increased DNA binding activity of NF-kappaB quantitatively similar to those induced by ischemic PC could be reproduced pharmacologically by giving the NO donor diethylenetriamine/NO (DETA/NO) (at a dose previously shown to elicit late PC), demonstrating that NO in itself can activate NF-kappaB in the heart. Taken together, these results provide direct evidence that activation of NF-kappaB is a critical step in the signal transduction pathway that underlies the development of the late phase of ischemic PC in conscious rabbits. The finding that four different pharmacological manipulations (L-NA, MPG, chelerythrine, and lavendustin A) produced similar inhibition of NF-kappaB suggests that this transcription factor is a common downstream pathway through which multiple signals elicited by ischemic stress (NO, ROS, PKC, tyrosine kinases) act to induce gene expression. To our knowledge, this is the first demonstration that NO can promote NF-kappaB activation in the heart, a finding that identifies a new biological function of NO and may have important implications for various pathophysiological conditions in which NO is involved and for nitrate therapy.  (+info)

Gender-related efficacy difference to an extended duration formulation of topical N,N-diethyl-m-toluamide (DEET). (4/74)

A clinical trial (n = 120, 60 males and 60 females) was conducted to assess the efficacy of an extended duration tropical insect/arthropod repellent (EDTIAR) topical formulation of N,N-diethyl-m-toluamide (DEET). The amount of EDTIAR (mean +/- confidence interval), applied by participants in accordance with label directions, was not significantly different between females (3.66 +/- 0.32 mg/cm2) and males (3.45 +/- 0.33 mg/cm2). There also was no significant difference in the number of Anopheles stephensi mosquitoes biting the control arm of females or males at 0, 3, 6, 9, and 12 hr. While gender had no effect on feeding, the time of day did effect mosquito feeding with fewer mosquitoes feeding in the afternoon than in the morning or evening. The percent protective efficacy at 0, 3, 6, 9, and 12 hr was 100.0, 99.3, 92.8, 79.7 and 66.3 for females, and 100.0, 100.0, 97.6, 91.9, and 77.5 for males. These data are inconsistent with the EDTIAR label claim that the repellent provides 95% or greater protection against mosquitoes for 12 hr or more under normal use conditions. The results of a multivariate regression analysis indicated that 1) protection decreased linearly as time after application of repellent increased (P < 0.001), 2) individuals who applied higher doses of repellent were better protected against mosquito bites (P < 0.001), 3) females experienced significantly less protection over time than did males (P = 0.005), and 4) the estradiol concentration in the blood had no effect on efficacy of the repellent (P = 0.110).  (+info)

Short report: prevention of Schistosoma mansoni infections in mice by the insect repellents AI3-37220 and N,N-diethyl-3-methylbenzamide. (5/74)

N,N-diethyl-3-methylbenzamide (DEET) has recently been reported to kill cercariae of Schistosoma mansoni in vitro. In addition, it blocked cercarial entry into mouse tail skin. We confirmed these results and compared the efficacy of DEET to a second insect repellent, 1-(3-Cyclohexen-1-yl-carbonyl)-2-methylpiperidine (AI3-37220), in preventing S. mansoni infections in mice. Both AI3-37220 and DEET conferred 100% protection against S. mansoni infection via percutaneous exposure to cercariae.  (+info)

Anticonvulsant-resistant seizures following pyridostigmine bromide (PB) and N,N-diethyl-m-toluamide (DEET). (6/74)

An acute toxic interaction has been described, in which sublethal doses of pyridostigmine bromide (PB) and the insect repellent N,N-diethyl-m-toluamide (DEET), when administered concomitantly, resulted in seizures and lethality. To investigate the possible relationships between seizures and lethality and the role of the cholinergic system in this interaction, PB (5 mg/kg), DEET (200 mg/kg) or PB (3 mg/kg) + DEET (200 mg/kg) were administered i.p. to male ICR mice, alone or following i.p. pretreatment, with one of several anticonvulsant agents: diazepam, 10 mg/kg; fosphenytoin, 40 mg/kg; phenobarbital, 45 mg/kg; or dextrophan, 25 mg/kg), or the anticholinergic agents, atropine (5 mg/kg), atropine methyl nitrate (2.7 mg/kg), or mecamylamine (2.5 mg/kg). The anticonvulsants selected for this study act through different mechanisms to reduce seizures. None of the anticonvulsants was able to reduce the incidence of seizures following treatment with PB, DEET or PB + DEET. Only diazepam delayed the onset of seizures. Fosphenytoin or diazepam significantly prolonged the time to lethality following PB, but only fosphenytoin reduced the incidence of PB-induced lethality. Diazepam or phenobarbital significantly prolonged the time to lethality following PB + DEET. Both atropine and atropine methyl nitrate protected against PB and PB + DEET-induced lethality and PB-induced seizures. Neither agent blocked seizures resulting from DEET or PB + DEET. Mecamylamine reduced seizures and lethality in PB-treated mice, but not in mice treated with DEET or PB + DEET. The results indicate that seizure activity is not a causative factor in the toxic interaction between PB and DEET. Furthermore, PB, DEET and PB + DEET induce seizures that are resistant to standard anticonvulsants, and each appears to operate through different mechanisms to produce seizures. Peripheral muscarinic receptors may play a specific role in lethality caused by PB + DEET.  (+info)

Nitric oxide selectively decreases interferon-gamma expression by activated human T lymphocytes via a cGMP-independent mechanism. (7/74)

The role of exogenous nitric oxide (NO) on the expression of interleukin (IL)-2, IL-4, IL-5 and interferon-gamma (IFN-gamma) by freshly isolated human T lymphocytes was investigated. The presence of NO, generated from any of the NO-donor compounds, S-nitroso-N-acetyl-D,L-penicillamine (SNAP), DPTA-nonoate (DPTA) or DETA-nonoate (DETA), added 15 min prior to T-cell stimulation (for 24 hr) with anti-CD3/anti-CD28 monoclonal antibodies (mAbs), resulted in up to 50% inhibition of IL-4, IL-5 and IFN-gamma secretion. In contrast, IL-2 secretion was not inhibited. Using the guanylate cyclase inhibitor, LY83583, it was shown that the inhibition of IL-4 and IL-5 was cGMP dependent, whereas additional mechanisms mediated the inhibition of IFN-gamma. Exposure of T cells to the NO-donor compounds for 24 hr prior to stimulation resulted in a more pronounced inhibition of IFN-gamma secretion by DPTA and DETA (P < 0.01), despite the fact that NO generation could no longer be detected. Under these conditions, IL-4 secretion was not inhibited and IL-5 secretion was inhibited to a lesser extent (P < 0.01 for SNAP and DPTA, P > 0.05 for DETA). IL-2 secretion was inhibited after 24 hr of preincubation with the NO-donor compounds, whereas it was not directly affected by NO. The increased inhibitory effects on IFN-gamma and IL-2 secretion could not be accounted for by the antiproliferative effects of the NO-donor compounds, which were diminished after 24 hr of preincubation relative to 15 min of preincubation. For IFN-gamma, the inhibition was at least partially effected at the transcriptional level as shown by decreased mRNA accumulation. These data show that NO can modulate the balance between the expression, by human T-lymphocytes, of T helper 1- and T helper 2-type cytokines, through selective and persistent inhibition of the expression of IFN-gamma via a cGMP-independent mechanism.  (+info)

Development and evaluation of LIPODEET, a new long-acting formulation of N, N-diethyl-m-toluamide (DEET) for the prevention of schistosomiasis. (8/74)

N, N-diethyl-m-toluamide (DEET) is a common and fairly safe active ingredient in many insect repellents. Our recent studies showed that when applied to the skin, DEET has a potent anti-parasitic effect against Schistosoma mansoni. However, the beneficial effects of DEET lasted only for a few minutes, presumably due to its rapid absorption through the skin. In this study, we evaluated different carrier formulations that prolong the activity of DEET in the skin. Among the various formulations analyzed, DEET incorporated into liposomes (LIPODEET) appeared to prolong the activity of DEET for more than 48 hr after a single application. Furthermore, LIPODEET was found to be minimally absorbed through the skin and loss due to washing off was limited. These findings thus suggest LIPODEET is a safe and long-acting formulation of DEET that is quite effective against schistosomiasis.  (+info)

The effect of skin application of N,N-diethyl-m-toluamide (DEET) on the penetration and migration behavior of cercariae of Schistosoma mansoni was evaluated in vitro and in vivo in a mouse model. These studies showed that DEET at concentrations of 7.5% or higher was 100% effective in immobilizing and killing cercariae of S. mansoni in vitro. Ultrastructural studies on such DEET-exposed cercariae showed transformative and degenerative changes involving both tegument and deeper parenchymal structures. Fatal tissue lesions were evident as early as 5 min postexposure to DEET, and became more extensive with increasing exposure time. Cutaneous application of DEET (as a pure chemical in isopropanol or as a commercial insect repellent preparation) was more than 99% effective in preventing entry of S. mansoni cercariae into the mouse tail skin. Radiolabeling and tracer studies confirmed that 7.5% DEET applied to the skin prior to infection was highly effective in preventing schistosomular migration to the lungs.
Evolution of insecticide resistance in Anopheles gambiae complex necessitates evaluation of alternative chemical classes to complement existing insecticides for long lasting insecticidal nets (LLIN) and indoor residual spraying (IRS). Microencapsulated (MC) DEET (N, N-diethyl-m-toluamide) is a formulation of the popular repellent, which gives long lasting activity when applied to nets. Its suitability for IRS use has not been evaluated before. This study assessed the efficacy of DEET MC, for IRS in experimental huts. DEET MC was tested alongside standard repellent and non-repellent residual insecticides: lambdacyhalothrin, permethrin, pirimiphos methyl and DDT. Residual formulations of these compounds were sprayed on plywood panels attached to walls of experimental huts to assess efficacy against pyrethroid resistant, wild free-flying Anopheles arabiensis and Culex quinquefasciatus. The panel treatments were rotated weekly between huts. The overall mortalities of An. arabiensis induced by the various
Every year, approximately one-third of the U.S. population uses mosquito repellants containing DEET to ward off mosquitoes and other pests.. At present, DEET is used in more than 230 products with concentrations up to 100 percent.. Duke University Medical Center pharmacologist Mohamed Abou-Donia has spent 30 years researching the effects of pesticides. He has found that prolonged exposure to DEET can impair functioning in parts of the brain.. Damage to these areas could result in problems with muscle coordination, muscle weakness, walking or even memory and cognition. Abou-Donia says rats given even small doses of DEET for 60 days had a harder time accomplishing even the easiest tasks. Abou-Donia says short-term exposure to DEET does not appear to be harmful, but warns against using any product with more than a 30 percent concentration. Use as little of the product as you can, and dont use a product containing DEET if youre taking any medication.. We found that the combined exposure to DEET ...
Oxidative metabolism of the insect repellentN,N-diethyl-m-toluamide (DEET) by pooled human liver microsomes (HLM), rat liver microsomes (RLM), and mouse liver microsomes (MLM) was investigated. DEET is metabolized by cytochromes P450 (P450s) leading to the production of a ring methyl oxidation product,N,N-diethyl-m-hydroxymethylbenzamide (BALC), and an N-deethylated product,N-ethyl-m-toluamide (ET). Both the affinities and intrinsic clearance of HLM for ring hydroxylation are greater than those for N-deethylation. Pooled HLM show significantly lower affinities (Km) than RLM for metabolism of DEET to either of the primary metabolites (BALC and ET). Among 15 cDNA-expressed P450 enzymes examined, CYP1A2, 2B6, 2D6*1 (Val374), and 2E1 metabolized DEET to the BALC metabolite, whereas CYP3A4, 3A5, 2A6, and 2C19 produced the ET metabolite. CYP2B6 is the principal cytochrome P450 involved in the metabolism of DEET to its major BALC metabolite, whereas CYP2C19 had the greatest activity for the formation ...
For children, repellents with DEET may be used. Repellent used on clothing use an ingredient called permethrin to repel insects. DEET repels mosquitos, ticks and other bugs.. For children and teenagers 30% DEET should be used. 30% DEET protects for 6 hours. For smaller babies 10% DEET preparations may be used. 10% DEET is only effective for 2 hours. DEET should not be used in babies below 2 months. Breast-feeding women may use DEET. DEET should not be put into eyes or mouth. If the child sucks his or her fingers or thumb the cream must be removed. DEET should be avoided over rashes, sunburns or open sores. Once the child is indoors DEET should be washed off with soap and water. Other insect repellents include Picaridin and Oil of lemon eucalyptus. The latter may be used for children over 3 years. Insect repellent for clothing is Permethrin. These repel mosquitoes and ticks. These have advantage of not being directly applied over the skin. When put on skin Permethrin loses its ...

A. It has long been known that the most effective repellents are those which contain DEET. DEET is the abbreviation for the chemical N,N-diethyl-meta-toluarnide. DEET has been sold in the United States since 1956 and is used by 50-100 million people each year. It repels mosquitoes, no-see-ums, fleas, ticks, gnats, horse flies, deer flies, yellow flies and chiggers. Repellents containing DEET are available as pump sprays,aerosols, lotions, creams, soaps and sticks. In general, the inexpensive products contain less than 10% DEET, while the more expensive ones are at least 20%DEET. There are over 40 products containing from 5% to 95% DEET which can be purchased. Products with more than 35% DEET are available, most often, through camping and outdoor supply stores. If a little DEET is good, is a lot of DEET better? Not necessarily. In tests done by the army, repellents with 30-40%DEET worked twice as well as repellents with 75% DEET. Read the label and check to see what percentage of the product is ...

Symptoms of DEET poisoning in exposed people include vomiting, rashes, drowsiness, headache, and seizures.. Children appear to be particularly susceptible, and some pediatricians recommend that DEET not be used on children.. In both laboratory animals and human cells, DEET has damaged DNA, the genetic material in living cells.. DEET can cross the placenta and move from a mother to her unborn child. When pregnant laboratory animals are exposed to DEET, the exposure has caused fetal loss and abnormal skeletons in the offspring.. Male laboratory animals exposed to DEET produced abnormal sperm.. Exposure to DEET in amounts equivalent to what people typically apply to their skin has affected the behavior and nervous system of laboratory animals. Effects include reduced sensory and motor skills, a reduction in the ability of the blood-brain barrier to pass molecules through to the brain, changes in the activity of an enzyme that helps transmit nerve impulses, and death of nerve cells in the ...

Powerful bug repellant DEET may do more than keep mosquitoes and other biting critters at bay-it might cause neurological damage in mammals, according to a study published in BioMed Central Biology.. Developed in 1946 by the U.S. Army, DEET has been used by the public for more than half a century to repel bugs like mosquitoes, along with the diseases they can carry. The new study, however, shows that DEET-aka N,N-diethyl-meta-toluamide-may be harmful for a variety of animal cells. In lab tests, it caused damage to mosquitoes, cockroach nerves, mouse muscles, and enzymes purified from fruit flies and humans. Applications of DEET slowed or halted the actions of the enzyme acetylcholinesterase. This enzyme hangs out between nerve and muscle cells, breaking down a messenger molecule after it has passed information from one cell to another. If this messenger isnt properly recycled, it can build up and lead to paralysis [Science News].. Although the findings certainly raise questions about the safety ...

As with all things baby related, there appears to be more paranoia around the issue than need be.. General consensus though is to try and avoid mozzie repellents and electric burners / mats that arent approved for use on babies / kids.. When it comes to repellents, the main chemical youre trying to avoid is DEET, which is the most common active ingredient in insect repellents (when reading product labels, look out for N-Diethyl-meta-toluamide or diethyltoluamide).. But even so, the American Academy of Paediatrics has still given Deet the green light for infants over 2 months of age! So its really not a train smash to use if nothing else seems to be working.

These bays are huge tourist attractions, and swimming in them, when permitted, is popular. Often the visitors have sprayed themselves with insect repellants containing the active ingredient DEET. The purpose of this paper is to examine the effects of DEET on the ability of the dinoflagellates to emit light.

The chemical I want to talk about today is a widely used and very useful chemical called N,N-diethyl-3-methylbenzamide. Most people know it by its acronym, DEET.. I was recently wondering just how DEET does its thing of making mosquitoes not bite people. (Why yes, the recent gap in my posts means I was on vacation. There may have been mosquitoes involved.) Obviously, I started by searching Google Scholar.. To my interest, it seems to be one of those (many) chemicals where science doesnt know exactly how it works, at least not well enough (yet) to synthesize a better fit based on that knowledge. There was some talk of specific chemical receptor targets in a few of the papers, but I didnt see anything in my searches about success in making a new repellent. From what I read, however, there is a pretty good understanding of the mechanism in general:. It seems mosquitoes think that humans smell tasty, and DEET smells bad.. Personally, I also think DEET spray smells bad, but it goes below my ...
A. There is no scientific evidence indicating that people can be chronically infected with West Nile virus. What remain in a person s body for long periods of time are antibodies and memory white blood cells (T-lymphocytes) that the body produces to the virus. These antibodies last for years, and may last for the rest of a person s life. Antibodies are what many diagnostic tests look for when testing blood. Both antibodies and memory T-lymphocytes provide future protection from the virus.. Q. If a person contracts West Nile virus, does that person develop a natural immunity to future infection by the virus? ...
DEET is the mother of all mosquito repellants. Its strong stench keeps bugs at bay by affronting their olfactory systems with an intensely offensive odor. But scientists are now running into a problem with DEETs effectiveness: after three hours the stuff no longer deters buzzing biters.. N,N-Diethyl-3-methylbenzamide, a.k.a. DEET, first emerged as a pesticide for crops, but the U.S. military then developed the chemical for use against biting insects in jungle environments during World War II. Available as a spray or a lotion, DEET is still used today to repel flies, ticks and mosquitoes, and to protect against the diseases these bugs can transmit.. But now, researchers in London have shown that three hours after Aedes aegypti mosquitoes were exposed to DEET, they seemed to become immune to the smell and were no longer repulsed by it. This species, also known as the yellow fever mosquito, is notorious for spreading tropical diseases.. Read More. ...
Protect yourself from mosquito bites. Apply a mosquito repellent to exposed skin when outdoors. The most effective repellents contain DEET (N, N-diethyl-metatoulamide). Follow all label directions carefully.. Non-DEET products provide some protection from mosquito bites but may not last as long as DEET products. Persons who are concerned about using products containing DEET may wish to consult their health care provider for advice..

Touhara and Vosshall developed their ion channel hypothesis in parallel with Vosshalls work on DEET, a widely used chemical in bug spray that jams the receptor complex. This research, which was published in Science last month, also showed that DEET jams other proteins that have nothing to do with smell, including several different types of ion channels that play important roles in the human nervous system. What these radically different proteins have in common, though, is that they all specifically inhibit the influx of positively charged ions into the cell. Now the curious result in the DEET paper showing that this insect repellent blocks insect olfactory receptors and unrelated ion channels makes sense, says Vosshall. I am optimistic that we can come up with blockers specific for this very strange family of insect olfactory ion channels ...
Apply permethrin-containi ng mosquito repellent to your clothing, shoes, and camping gear and bed netting. You can also buy clothing made with permethrin already in it. Use repellent with a 10 percent to 30 percent concentration of DEET to your skin. Choose the concentration based on the hours of protection you need - a 10 percent concentration of DEET is effective for about two hours, whereas higher concentrations last longer. Keep in mind that chemical repellants can be toxic, and use only the amount needed for the time youll be outdoors. Dont use DEET on the hands of young children or on infants under 2 months of age. Instead, cover your infants stroller or playpen with mosquito netting when outside. According to the Centers for Disease Control and Prevention, oil of lemon eucalyptus, a more natural product, offers the same protection as DEET when used in similar concentrations.. This entry was posted on Tuesday, October 18th, 2011 at 8:13 am and is filed under Dengue. You can follow any ...
Wear long-sleeved shirts, long pants, socks and shoes when outdoors in the evening or early morning.. * Whenever you use mosquito repellent, apply a product containing DEET, and carefully read and follow the manufacturers directions.. * The concentration of DEET should be no more than 30 percent for adults, and no more than 10 percent for children.. * Repellent containing DEET should not be used on children under six months of age. It should be applied to children between six months and two years of age only in situations where there is a high risk of complications from insect bites, and then only once per day. Children two to 12 years of age should not apply DEET more than three times per day. Additionally, residents are reminded to drain areas of standing or stagnant water on their property on a regular basis, including bird baths, old tires, pails, toys and wheelbarrows. Make sure all windows and doors in your home have screens that are in good condition.. ...

Pesticide properties for 3,5-dichloro-N-(2-carboxy-1-ethyl-1-methyl-2-oxoethyl)-4-methylbenzamide, including approvals, environmental fate, eco-toxicity and human health issues
I hope youre paying close attention to what Im explaining here, because what the study mentioned above reveals is that DEET is part of a binary chemical weapon system that goes ballistic against your nerve cells when combined with certain classes of insecticides (such as carbamates and OPs).. What are carbamate insecticides? They are a class of pesticide chemicals that are right now being sprayed on food crops all across America. Even worse, theyre often used in aerial spraying campaigns in combination with DEET. In effect, this is a chemical binary weapon now being deployed against the American people.. Deet is commonly used in combination with insecticides and we show that deet has the capacity to strengthen the toxicity of carbamates, a class of insecticides known to block acetylcholinesterase, says the BioMedCentral science paper linked above.. Adding to the concern, this warning from MDguidelines.com explains, Over 80% of the pesticide poisonings in the US are caused by ...

A Polymer is a long thread-like chain formed by attachment of similar molecules. Poly(methyl methacrylate) (PMMA) is one of the most widely produced polymer in the world today. It is formed by polymerizing or attaching methylmethacrylate (MMA) and is used in household items, in paints and as a substitute for glass. PMMA is compatible with the human body so it has several biomedical applications also which includes dental bases, bone filler and intraocular lens.. Glycerol is a highly hydrophilic or water-loving species, a byproduct obtained from the soap making process and from the biofuel industry. It is also generated by hydrolysis of coconut oil. It mainly finds its application as a sweetening agent, stabilizer in food industries and humectants in cosmetic formulations.. As part of our project we cross-linked or tied up PMMA chains while synthesizing it using glycerol to form a 3D polymer network to encapsulate N,N-diethyl-m-toluamide (DEET), a mosquito repellant. The networks were ...

Check with your doctor before visiting a region that is at high risk for malaria to discuss the use of antimalarial medications. Antimalarial medications decrease your risk of developing symptomatic malaria; however they do not provide 100% protection against the disease. To be effective you will have to begin taking these medications prior to your trip and continue to take them after your trip is over. It is recommended that travelers to areas where malaria occurs protect themselves from mosquito bites. Wear clothing that reduces the amount of exposed skin; wear light-coloured, long-sleeved, tucked-in shirts, long pants, shoes (not sandals), and a hat. Use insect repellant on exposed skin (of the insect repellants registered in Canada, those containing DEET are the most effective). Use as directed by the manufacturer paying attention to concentration of DEET, frequency and age of end user. Most repellents containing natural products are effective for shorter durations than DEET and for this ...
Personally I have not found DEET under socks and long pants to be effective at keeping those ankle-biters from enjoying a meal. Maybe it wasnt strong enough. Some preparations say 10% in tiny print. Some preparations have 30% or more. I dont care to take a bath in it every 8 hours, and pregnant women who are taking the precaution of using a 6% preparation need to apply it every two hours. An EPA official proclaimed DEET to be safe at any stage of pregnancy, but there is a paucity of research, especially in the first trimester.. DEET does have hazards. It is flammable and potentially explosive. It can cause skin corrosion and serious eye damage. It is an acute and long-term hazard to aquatic animals. (But at least it doesnt cause global warming.). For troops anticipating heavy mosquito exposure, the military has uniforms pre-treated with permethrin. You can treat clothing yourself, but be careful: permethrin is highly toxic to cats.. CDC and Florida are applying insecticides, but though they ...
When you use any products, always read its labels mentioned on the product carefully because protection varies from product to product.. Repellency Awareness Graphic will show you which of the bug spray is effective against which product, and it will work for how long?. Products have graphic awareness on its label if they are adequate to prove to the United States Environmental Agency about its effectiveness.. So take a look on it, that the bug spray has it or not.. The second important thing to remember, never thing if the product has a lower concentration of active ingredients it means that it is less effective than other products.. It means that this product will not keep the bugs away for an extended period; you have to reapply it after some time.. Such as if the product has 10 % DEET quantity that it will remain active till two hours, while the products which have 24% concentration it will keep the bug away from your kids for five hours.. DEET ingredients have the maximum duration to keep ...

TEXT ATTACHMENT -------- SENT 12-31-97 FROM ROBINSON_BRIAN @SNAX == I have a few more trivial questions that are pestering my brain late a == night. Heres a few more trivial answers. :-) == Boots and swollen feet I wore Raicle Montagnes for the first 1200 miles. These are perhaps the biggest, heaviest leather boots around. These were well broken in before the trip. (A MUST for boots) After a couple days I had to reduce from 2 to 1 pair of socks and still I lost a toenail to the tight fit. The swelling reduced after a couple weeks, but was never entirely gone, especially after a rest day. My impression is that lighter boots and shoes cause at least as much swelling because theres less foot protection, but they stretch more. Heavy boots keep your feet a little drier in wet conditions, but take much longer to dry out, so theres no advantage there. I also found that swelling, which occurs mostly at night, can be reduced by sleeping with your feet slightly uphill. Try it when your feet are sore ...

DEET (N,N-diethyl-meta-toluamide) is the worlds most widely used topical insect repellent, with broad effectiveness against most insects. Its mechanism of action and molecular target remain unknown. Here, we show that DEET blocks electrophysiological responses of olfactory sensory neurons to attractive odors in Anopheles gambiae and Drosophila melanogaster. DEET inhibits behavioral attraction to food odors in Drosophila, and this inhibition requires the highly conserved olfactory co-receptor OR83b. DEET inhibits odor-evoked currents mediated by the insect odorant receptor complex, comprising a ligand-binding subunit and OR83b. We conclude that DEET masks host odor by inhibiting subsets of heteromeric insect odorant receptors that require the OR83b co-receptor. The identification of candidate molecular targets for the action of DEET may aid in the design of safer and more effective insect repellents. |P /|

An insect repellent (also commonly called bug spray) is a substance applied to skin, clothing, or other surfaces which discourages insects (and arthropods in general) from landing or climbing on that surface. Insect repellents help prevent and control the outbreak of insect-borne (and other arthropod-bourne) diseases such as malaria, Lyme disease, dengue fever, bubonic plague, river blindness and West Nile fever. Pest animals commonly serving as vectors for disease include insects such as flea, fly, and mosquito; and the arachnid tick[citation needed]. Some insect repellents are insecticides (bug killers), but most simply discourage insects and send them flying or crawling away. Almost any might kill at a massive dose without reprieve, but classification as an insecticide implies death even at lower doses[citation needed].

DEET is a chemical used in insect repellents. The amount of DEET in insect repellents varies from product to product, so its important to read the label of any product you use. The amount of DEET may range from less than 10% to more than 30%. DEET greater than 30% doesnt offer any additional protection.. Studies show that products with higher amounts of DEET protect people longer. For example, products with amounts around 10% may repel pests for about 2 hours, while products with amounts of about 24% last an average of 5 hours. But studies also show that products with amounts of DEET greater than 30% dont offer any extra protection. The AAP recommends that repellents should contain no more than 30% DEET when used on children. Insect repellents also are not recommended for children younger th​an 2 months. ...

Washington, August 5 (ANI): Scientists are calling for more research into the toxicity of deet, an active ingredient in many insect repellents, after it has been found to be harmful to the central nervous system.. Vincent Corbel from the Institut de Recherche pour le Développement in Montpellier, and Bruno Lapied from the University of Angers, France, led a team of researchers who investigated the mode of action and toxicity of deet.. Corbel said: Weve found that deet is not simply a behavior-modifying chemical but also inhibits the activity of a key central nervous system enzyme, acetycholinesterase, in both insects and mammals.. In a series of experiments, his research team found that deet inhibits the acetylcholinesterase enzyme - the same mode of action used by organophosphate and carbamate insecticides.. The researchers also found that deet interacts with carbamate insecticides to increase their toxicity.. Corbel concludes: These findings question the safety of deet, particularly in ...

The American Academy of Pediatrics and the Centers for Disease Control and Prevention both agree that for children older than two months of age repellents containing 10 percent to 30 percent DEET should be used. DEET should not be used on children younger than two months of age. Repellents should never be applied to childrens hands, around the eyes or to cuts.. The effectiveness is similar for 10 percent to 30 percent DEET, but the duration of effect varies. Ten percent DEET provides protection for about two hours, whereas 30 percent protects for about five hours. Parents should choose the lowest concentration that covers the required amount of time. Never use insect repellent meant for pets on people and never use repellents meant for people on pets.. The U.S. Food and Drug Administration does not recommend the use of combination sunscreen/insect repellent. Sunscreen needs to be reapplied every two hours, and insect repellent should not be reapplied. Parents can apply both an insect repellent ...

As warm weather arrives in the US, the number of insect bites and stings reported to poison control centers increases dramatically. More than just an annoyance, insect bites can spread disease. The growing concern about the mosquito-borne Zika virus emphasizes this danger.. An insect repellent (IR) is defined as a chemical that makes the air within about 1.5 inch above human skin obnoxious enough to insects that they are less likely to land and bite. Current guidelines require IRs to provide at least a 50% repellency rate to make a reliable claim that they repel mosquitoes. IRs are divided into two chemical classes: synthetic chemicals such as DEET (N,N-diethyl-3-methylbenzamide), picaridin and IR3535; and plant-derived oils such as oil of lemon eucalyptus and oil of citronella. Picaridin is a relatively new IR. Compared with DEET, its advantages include lack of chemical odor, non-greasy consistency, and non-damaging to clothing and plastics. Its vapor is noxious to mosquitoes, flies, chiggers, ...
DEET is a reliable and highly effective insect repellent. The chemical has been in public use since 1957. The repellent is sold under numerous brand names and comes in lotion, spray and many other forms. Concentrations of DEET range from about 5% all the way up to 100%. Products with 10% to 35% DEET will provide adequate protection under most circumstances. Products with concentrations higher than about 50% do not offer significantly greater protection. For example, 50% DEET provides about 4 hours of protection against mosquitoes, but increasing the concentration to 100% gives only about one extra hour of protection. DEET should be used with proper precautions, especially in children, who can experience irritation or other reactions after swallowing or prolonged skin application. However, if DEET products in moderate concentrations are used according to directions, they are considered safe. The American Academy of Pediatrics recommends that repellents used on children contain no more than 30% ...
Background Insect repellents are prophylactic tools against a number of vector-borne diseases. There is growing demand for repellents outperforming DEET in cost and safety, but with the current technologies R&D of a new product takes almost 10 years, with a prohibitive cost of $30 million dollar in part due to the demand for large-scale synthesis of thousands of test compounds of which only 1 may reach the market. R&D could be expedited and cost dramatically reduced with a molecular/physiological target to streamline putative repellents for final efficacy and toxicological tests. Methodology Using olfactory-based choice assay we show here that the fruit fly is repelled by not only DEET, but also IR3535 and picaridin thus suggesting they might have
USA Today has published an article asking this question. They point out that there is no 100% failsafe protection against bug bites. They cite 4 compounds that are effective: 3 chemicals, including DEET, and oil of lemon eucalyptus, an essential oil. PubMed has studies showing catnip essential oil is as effective as DEET. (If you want links to the full articles, just email me!) Oil of lemon eucalyptus was recognized by the Centre for Disease Control as being both effective, and safe to use. That is not true here in Canada, though. In Canada, Health Canada does not allow the use of citronella, or, anything containing citronellol to be used as an insect repellent. Oil of lemon eucalyptus does have citronnellol as a component. ...

The most common of these are based on DEET (diethyl-meta-toluamide) which is a very effective insect repellent developed in America some years ago but which can cause irritation to eyes, lips and other sensitive areas.

Abstract: Dengue hemorrhagic fever has been one of the major health problems in Indonesia. As the disease spreads out by Aedes aegypti, a variety of ways has been conducted to disconnect host, agent, and the environment chain including prevention of human contact with the vector using by various repellents. The present test compared the complete protection time of N,N-diethyl- 3-metatoluamide (DEET) and citronella oil impregnated in wet tissue against Aedes aegypti. For this test, an ethanol-based 12.5% DEET and 20% citronella oil were prepared, into which dry tissue papers were immersed, drain in open air, and then stored in aluminum foil packs for one day and one week. Meanwhile, a number of disease-free adult female Aedes aegypti were placed in mosquito cages. The prepared one-day and oneweek stored wet tissues were used to swab volunteer adult human hands (from elbow to wrist) which were then inserted into the mosquito cage in three replicates (25 mosquitoes each cage).
