Long-term effects of N-2-chlorethyl-N-ethyl-2-bromobenzylamine hydrochloride on noradrenergic neurones in the rat brain and heart. (1/2065)

1 N-2-Chlorethyl-N-ethyl-2-bromobenzylamine hydrochloride (DSP 4) 50 mg/kg intraperitoneally, produced a long-term decrease in the capacity of brain homogenates to accumulate noradrenaline with significant effect 8 months after the injection. It had no effect on the noradrenaline uptake in homogenates from the striatum (dopamine neurones) and on the uptake of 5-hydroxytryptamine (5-HT) in various brain regions. 2 In vitro DSP 4 inhibited the noradrenaline uptake in a cortical homogenate with an IC50 value of 2 muM but was more than ten times less active on the dopamine uptake in a striatal homogenate and the 5-HT uptake in a cortical homogenate. 3 DSP 4 (50 mg/kg i.p.) inhibited the uptake of noradrenaline in the rat heart atrium in vitro but this action was terminated within 2 weeks. 4 DSP 4 (50 mg/kg i.p.) cuased a decrease in the dopamine-beta-hydroxylase (DBH) activity in the rat brain and heart. The onset of this effect was slow; in heart a lag period of 2-4 days was noted. In brain the DBH-activity in cerebral cortex was much more decreased than that in hypothalamus which was only slightly affected. A significant effect was still found 8 months after the injection. The noradrenaline concentration in the brain was greatly decreased for at least two weeks, whereas noradrenaline in heart was only temporarily reduced. 5 The long-term effects of DSP 4 on the noradrenaline accumulation, the DBH activity and noradrenaline concentration in the rat brain were antagonized by desipramine (10 mg/kg i.p.). 6 It is suggested that DSP 4 primarily attacks the membranal noradrenaline uptake sites forming a covalent bond and that the nerve terminals, as a result of this binding, degenerate.  (+info)

Analysis of gabapentin in serum and plasma by solid-phase extraction and gas chromatography-mass spectrometry for therapeutic drug monitoring. (2/2065)

A simple method for the determination of gabapentin (Neurontin) is described. The method uses solid-phase extraction by disk column and derivatization followed by gas chromatographic-mass spectrometric analysis. The single-step derivatization with MTBSTFA produces a t-BDMS derivative of both the carboxylic and amine moieties of the molecule. Each step of the procedure was optimized to assure reliable performance of the method. The assay limit of detection was 0.1 microg/mL with a linear range from 1.0 to 35 microg/mL. Within-run (n = 3) and between-run (n = 40) coefficients of variation were less than 8.2 and 15.9%, respectively. The method has proven reliable in routine production for more than a year, producing clean chromatography with unique ion fragments, consistent ion mass ratios, and no interferences. Statistical analysis of the gabapentin concentrations measured in 1020 random specimens over a 2-month period showed a mean concentration of 6.07 microg/mL with a standard deviation of 5.28.  (+info)

Gabapentin suppresses ectopic nerve discharges and reverses allodynia in neuropathic rats. (3/2065)

Repetitive ectopic discharges from injured afferent nerves play an important role in initiation and maintenance of neuropathic pain. Gabapentin is effective for treatment of neuropathic pain but the sites and mechanisms of its antinociceptive actions remain uncertain. In the present study, we tested a hypothesis that therapeutic doses of gabapentin suppress ectopic afferent discharge activity generated from injured peripheral nerves. Mechanical allodynia, induced by partial ligation of the sciatic nerve in rats, was determined by application of von Frey filaments to the hindpaw. Single-unit afferent nerve activity was recorded proximal to the ligated sciatic nerve site. Intravenous gabapentin, in a range of 30 to 90 mg/kg, significantly attenuated allodynia in nerve-injured rats. Furthermore, gabapentin, in the same therapeutic dose range, dose-dependently inhibited the ectopic discharge activity of 15 injured sciatic afferent nerve fibers through an action on impulse generation. However, the conduction velocity and responses of 12 normal afferent fibers to mechanical stimulation were not affected by gabapentin. Therefore, this study provides electrophysiological evidence that gabapentin is capable of suppressing the ectopic discharge activity from injured peripheral nerves. This action may contribute, at least in part, to the antiallodynic effect of gabapentin on neuropathic pain.  (+info)

Removal of non-specific serum inhibitors of haemagglutination of rubella virus by treatment with dodecylamine-gel. (4/2065)

The suitability of using dodecylamine-gel for removing the serum non-antibody-like inhibitors of haemagglutination by rubella was studied. Compared with kaolin and MnCl2/heparin treatment this new procedure appears to have a higher specificity since it removes the non-antibody-like inhibitors from serum without affecting the immunoglobulin level significantly. The potential application of this procedure in routine serological analysis for rubella virus infection is discussed.  (+info)

N-acetyltransferase 1 genetic polymorphism, cigarette smoking, well-done meat intake, and breast cancer risk. (5/2065)

N-Acetyltransferase 1 (NAT1), encoded by the polymorphic NAT1 gene, has been shown to be one of the major enzymes in human breast tissue that activates aromatic and heterocyclic amines. Humans are mainly exposed to these carcinogens through cigarette smoking and consumption of well-done meat. To test the hypothesis that variations in the NAT1 gene are related to breast cancer risk, particularly among women who smoke or consume high levels of well-done meat, a nested case-control study was conducted in a prospective cohort study of 41,837 postmenopausal Iowa women. Information on cigarette smoking and other breast cancer risk factors was obtained at the baseline survey conducted in 1986. DNA samples and information on the consumption of well-done meat were obtained, in the case-control study, from breast cancer cases diagnosed from 1992 to 1994 and a random sample of cancer-free cohort members. Genomic DNA samples obtained from 154 cases and 330 controls were assayed for 11 NAT1 alleles (NAT1*3, *4, *5, *10, *11, *14, *15, *16, *17, *19, and *22). The NAT1*4 allele was the predominant allele observed in this study population, accounting for 73.2% (72.4% in cases versus 73.8% in controls) of the total alleles analyzed. Compared to controls, breast cancer cases had a slightly higher frequency of the NAT1*10 allele (18.8% in cases versus 17.3% in controls) and a substantially higher frequency of the NAT1*11 allele (3.6% versus 1.2%). In multivariate analyses, we found a 30% [95% confidence interval (CI) = 0.8-1.9] elevated risk of breast cancer associated with the NAT1*10 allele and a nearly 4-fold (95% CI = 1.5-10.5) elevated risk associated with the NAT1*11 allele. The positive association of breast cancer with the NAT1*11 allele was more evident among smokers [odds ratio (OR) = 13.2, 95% CI = 1.5-116.0] and those who consumed a high level of red meat (OR = 6.1, 95% CI = 1.1-33.2) or consistently consumed their red meat well done (OR = 5.6, 95% CI = 0.5-62.7). The association of the NAT1*10 allele with breast cancer was mainly confined to former smokers (OR = 3.3, 95% CI = 1.2-9.5). These findings are consistent with a role for the NAT1 gene in the etiology of human breast cancer.  (+info)

An in vitro electrophysiological study on the effects of phenytoin, lamotrigine and gabapentin on striatal neurons. (6/2065)

We performed intracellular recordings from a rat corticostriatal slice preparation in order to compare the electrophysiological effects of the classical antiepileptic drug (AED) phenytoin (PHT) and the new AEDs lamotrigine (LTG) and gabapentin (GBP) on striatal neurons. PHT, LTG and GBP affected neither the resting membrane potential nor the input resistance/membrane conductance of the recorded cells. In contrast, these agents depressed in a dose-dependent and reversible manner the current-evoked repetitive firing discharge. These AEDs also reduced the amplitude of glutamatergic excitatory postsynaptic potentials (EPSPs) evoked by cortical stimulation. However, substantial pharmacological differences between these drugs were found. PHT was the most effective and potent agent in reducing sustained repetitive firing of action potentials, whereas LTG and GBP preferentially inhibited corticostriatal excitatory transmission. Concentrations of LTG and GBP effective in reducing EPSPs, in fact, produced only a slight inhibition of the firing activity of these cells. LTG, but not PHT and GBP, depressed cortically-evoked EPSPs increasing paired-pulse facilitation (PPF) of synaptic transmission, suggesting that a presynaptic site of action was implicated in the effect of this drug. Accordingly, PHT and GBP, but not LTG reduced the membrane depolarizations induced by exogenously-applied glutamate, suggesting that these drugs preferentially reduce postsynaptic sensitivity to glutamate released from corticostriatal terminals. These data indicate that in the striatum PHT, LTG and GBP decrease neuronal excitability by modulating multiple sites of action. The preferential modulation of excitatory synaptic transmission may represent the cellular substrate for the therapeutic effects of new AEDs whose use may be potentially extended to the therapy of neurodegenerative diseases involving the basal ganglia.  (+info)

Cancer chemopreventive mechanisms of tea against heterocyclic amine mutagens from cooked meat. (7/2065)

Cooking meat and fish under normal conditions produces heterocyclic amine mutagens, several of which have been shown to induce colon tumors in experimental animals. In our search for natural dietary components that might protect against these mutagens, it was found that green tea and black tea inhibit the formation of heterocyclic amine-induced colonic aberrant crypt foci (ACF) in the rat. Since ACF are considered to be putative preneoplastic lesions, we examined the inhibitory mechanisms of tea against the heterocyclic amines. In the initial studies using the Salmonella mutagenicity assay, green tea and black tea inhibited according to the concentration of tea leaves during brewing and the time of brewing; a 2-3-min brew of 5% green tea (w/v) was sufficient for >90% antimutagenic activity. N-hydroxylated heterocyclic amines, which are direct-acting mutagens in Salmonella, were inhibited by complete tea beverage and by individual components of tea, such as epigallocatechin-3-gallate (EGCG). Inhibition did not involve enhanced mutagen degradation, and EGCG and other catechins complexed only weakly with the mutagens, suggesting electrophile scavenging as an alternative mechanism. Enzymes that contribute to the metabolic activation of heterocyclic amines, namely microsomal NADPH-cytochrome P450 reductase and N, O-acetyltransferase, were inhibited by tea in vitro. Studies in vivo established that tea also induces cytochromes P450 and Phase II enzymes in a manner consistent with the rapid metabolism and excretion of heterocyclic amines. Collectively, the results indicate that tea possesses anticarcinogenic activity in the colon, and this most likely involves multiple inhibitory mechanisms.  (+info)

Phospholipid-assisted refolding of an integral membrane protein. Minimum structural features for phosphatidylethanolamine to act as a molecular chaperone. (8/2065)

Escherichia coli-derived phosphatidylethanolamine (PE) or PE with fully saturated fatty acids was able to correct in vitro a defect in folding in the lipid-dependent epitope 4B1 of lactose permease (LacY) resulting from in vivo assembly in the absence of PE. PE plasmalogen, PE with two unsaturated fatty acids, and lyso-PE, which all do not favor bilayer organization, did not support proper refolding. Proper refolding occurred when these latter lipids were mixed with a bilayer-forming lipid (phosphatidylglycerol), which alone could not support refolding. L-Phosphatidylserine (PS; natural diastereomer) did support proper refolding. PE derivatives of increasing degrees of methylation were progressively less effective in supporting refolding, with phosphatidylcholine being completely ineffective. Therefore, the properties of nonmethylated aminophospholipids capable of organization into a bilayer configuration are essential for the recovery of the native state of epitope 4B1 after misassembly in vivo in the absence of PE. Neither D-PS (sn-glycero-1-phosphate backbone) nor P-D-S (D-serine in the head group) is competent in supporting proper refolding unless used in binary mixtures with phosphatidylglycerol. The detailed characterization of phospholipid-assisted refolding reported here further supports a specific rather than nonspecific role for PE in structural maturation of lactose permease in vivo (Bogdanov, M., and Dowhan, W. (1998) EMBO J. 17, 5255-5264).  (+info)

Compounds having two reactive functional groups are described that can be used as a tethering compound to immobilize an amine-containing material to a substrate. The first reactive functional group can be used to provide attachment to a surface of a substrate. The second reactive functional group is a N-sulfonyldicarboximide group that can be reacted with an amine-containing material, particularly a primary aliphatic amine, to form a connector group between the substrate and the amine-containing material. The invention also provides articles and methods for immobilizing amine-containing materials to a substrate.
Comparative scavenging of amines (0.2-0.05 M) of varying reactivity was tested as a function of time and temperature (Table 1). Typical aliphatic amines are completely sequestered by three equivalents of PS-Isocyanate within 1 h. Three equivalents of PS-Isocyanate sequestered 100% aniline at room temperature over 16 h. A less reactive aromatic amine, 2-aminobenzophenone, was not completely sequestered even at elevated temperatures. The use of DIEA as a catalyst did not improve the scavenging efficiency of PS-Isocyanate towards aromatic amines. Alcohols were not reactive towards PS-Isocyanate at room temperature, suggesting that aliphatic amines can be selectively sequestered in the presence of alcohol functionality.

Heterocyclic amines are a group of chemical compounds, many of which can be formed during cooking. They are found in meats that are cooked to the "well done" stage, in pan drippings and in meat surfaces that show a brown or black crust. Epidemiological studies show associations between intakes of heterocyclic amines and cancers of the colon, rectum, breast, prostate, pancreas, lung, stomach/esophagus and animal feeding experiments support a causal relationship. The U.S. Department of Health and Human Services Public Health Service labeled several heterocyclic amines as likely carcinogens in its 13th Report on Carcinogens. Changes in cooking techniques reduce the level of heterocyclic amines. More than 20 compounds fall into the category of heterocyclic amines, often abbreviated HCAs[1]. Table 1 shows the chemical name and abbreviation of those most commonly studied. All four of these compounds are included in the 13th Report on Carcinogens. The compounds found in food are formed when creatine (a ...

Aromatic amines are a widespread class of environmental contaminants present in various occupational settings and tobacco smoke. Exposure to aromatic amines is a major risk factor for bladder cancer development. The etiologic involvement of aromatic amines in the genesis of bladder cancer is attributable to their ability to form DNA-adducts, which upon eluding repair and causing mispairing during replication, may initiate mutagenesis. We have investigated the induction of DNA-adducts in relation to mutagenesis in bladder and various non-target organs of transgenic Big Blue® mice treated weekly (i.p.) with a representative aromatic-amine compound, 4-aminobiphenyl (4-ABP), for six weeks, followed by a six-week recovery period. We demonstrate an organ-specificity of 4-ABP in inducing repair-resistant DNA-adducts in bladder, kidney and liver of carcinogen-treated animals, which accords with the bioactivation pathway of this chemical in the respective organs. In confirmation, we show a predominant ...
This invention relates to certain cyclic amine derivatives of Formula (I) that are CCR-3 receptor antagonists, pharmaceutical compositions containing them, methods for their use and methods for preparing these compounds.
Amine dehydrogenase (AmDH) possesses tremendous potential for the synthesis of chiral amines because AmDH catalyzes the asymmetric reductive amination of ketone with high enatioselectivity. Although a reductive application of AmDH is favored in practice, the oxidative route is interesting as well for the preparation of chiral amines. Here, the kinetic resolution of racemic amines using AmDH was first extensively studied, and the AmDH reaction was combined with an NADH oxidase (Nox) to regenerate NAD+ and to drive the reaction forward. When the kinetic resolution was carried out with 10 mM rac-2-aminoheptane and 5 mM rac-α-methylbenzylamine (α-MBA) using purified enzymes, the enantiomeric excess (ee) values were less than 26% due to the product inhibition of AmDH by ketone and the inhibition of Nox by the substrate amine. The use of a whole-cell biocatalyst co-expressing AmDH and Nox apparently reduces the substrate and product inhibition, and/or it increases the stability of the enzymes. Fifty
Since the publication of Guggenheims book "Die Biogenen Amine" in 1951, knowledge about the endogenous amines has steadily been increasing. Research on the cellular a subcellular distribution of the amines, as well as the mechanisms involved in the release and uptake of these amines has been proceeding apace (Davis et a!., 1978). Certain of these amines in addition to their function as neurotransmitters also serve the function of hormones. Abnormalities in the synthesis, release or metabolism of these amines are associated with a number of diseases including pheochromocytoma, neuroblastoma, schizophrenia, depressive disorders and Parkinsons disease (Keller et al., 1976). A prerequisite to the determination of the roles which these amines play in the pathogenesis of diseases is a sensitive method for the determination of their concentration in biological fluids and tissues. Various methods including fluorescence, gaschromatography and mass spectrometry have been developed for amine ...

By combining leucine (Leu) and tetraphenylethene (TPE), a pH-sensitive aggregation induced emission (AIE) probe TPE-Leu was developed. The aliphatic amine in TPE-Leu was more easily protonated under acidic conditions, which made TPE-Leu more water soluble. Therefore, the protonated AIE probe showed weak fluorescenc
Im guessing you are referring to scromboid poisoning. This is caused by the ingestion of foods that contain high levels of histamine and possibly other vasoactive amines and compounds. Histamine and other amines are formed by the growth of certain bacteria and the subsequent action of their decarboxylase enzymes on histidine and other amino acids in food, either during the production of a product such as Swiss cheese or by spoilage of foods such as fishery products, particularly tuna or mahi mahi. However, any food that contains the appropriate amino acids and is subjected to certain bacterial contamination and growth may lead to scombroid poisoning when ingested. Scombroid poisoning remains one of the most common forms of fish poisoning in the United States. Even so, incidents of poisoning often go unreported because of the lack of required reporting, a lack of information by some medical personnel, and confusion with the symptoms of other illnesses. Difficulties with underreporting are a ...
3-(p-Trifluoromethylphenoxy)-N-methyl-3-phenylpropylamine (Lilly 110140), when injected into rats at i.p. doses of 1 to 10 mg/kg, prevented the lowering of brain serotonin by 4-chloroamphetamine. The duration of 110140 action was very long, significant antagonism of 4-chloroamphetamine action being apparent still at 48 hours after a single dose of 10 mg/kg of 110140. The N,N-dimethyl tertiary amine derivative was as effective as 110140 itself in antagonizing serotonin depletion by 4-chloroamphetamine, but other structurally related compounds had less activity or were inactive. Likewise, six tricyclic antidepressant drugs injected at 10 mg/kg i.p. did not antagonize the action of 4-chloroamphetamine. When injected into rats whose brain serotonin levels had already been depleted by 3-hour pretreatment with 4-chloroamphetamine, 110140 terminated the action of 4-chloroamphetamine and permitted serotonin levels to return to normal. Lilly 110140 did not antagonize the depletion of brain serotonin or ...

An improved method for amine regeneration wherein a rich amine out of a first heat exchanger is temperature controlled prior to transfer to a second heat exchanger. At least a portion of the hot overhead gasses exiting from a stripping still are transferred to the second heat exchanger. Temperature controlled heated rich amine liquid passes through the second exchanger and contacts the hot overhead gasses. The rich amine liquid is increased in higher temperature thereby and then is transferred to yet a third exchanger and finally to the stripping still for regeneration of lean amine. The reduced temperature overhead gasses are transferred to the reflux condensor for final cooling.

Many of the molecules contain more than one ionizable group. Only the pKa values of the amine indicated in Eckert and Klamts Table 3 are computed and the protonation states are prepared according standard pKa values. For example, for phenylalanine the carboxyl group is deprotonated because the "standard" pKa values of a carboxyl group (e.g. in acetic acid) is lower than the standard pKa values of a primary amine (e.g. ethylamine). Notice that the cyanoguanidine group in cimetidine has a pKa value of about 0 and is therefore deprotonated when the imidazole group titrates. Eckert and Klamt characterised the histamine pKa value of 9.7 as an amidine pKa and the thenyldiamine pKa as a pyridine pKa. This is corrected to a primary amine and tertiary amine, respectively. Also, the experimental pKa values of morphine and niacin are changed to 8.2 and 4.2, respectively, while the remaining experimental pKa values are taken from Eckert and Klamt ...

For docking, we followed the original proposal of Ragsdale et al. (1994) that the alkylamine group is located higher, near Phe-1579 and close to the selectivity filter, and the aromatic ring is lower and close to Tyr-1586, near the activation gate in the open state. A number of experimental observations support this orientation. For example, the permanent charge on QX-314 is located deep in the membrane field, 70% of the transmembrane voltage from the inner mouth (Gingrich et al., 1993). Sunami et al. (1997) showed that lidocaine was electrostatically affected by the positively charged lysine in the selectivity filter, but neutral analogs were not affected, placing the amine end of lidocaine within approximately 10 Å of the domain III lysine of the selectivity ring. Substitution of lysine for Tyr-1586 and Asn-434 of Nav1.4 at the bottom of the proposed binding site produced rather small reductions in affinity (Wang et al., 1998b; Wright et al., 1998; Nau et al., 1999), whereas substitution by ...
Disclosed are methods of producing super-absorbing polymeric networks of polyaspartates from crosslinked polysuccinimide. In one preferred aspect, polysuccinimide is first reacted with an organic crosslinking agent, preferably an organic base containing at least two primary amine groups, to form a gelled crosslinked polysuccinimide. The gelled crosslinked polysuccinimide is then base hydrolyzed to a gelled polymeric network of polyaspartate and deswollen with at least one liquid alcohol to a polymeric network of polyaspartate which demonstrates super-absorbing capability in water and in electrolyte solution. Super-absorbing polymeric networks of polyaspartates can also be produced in a single reaction vessel by sequentially crosslinking a polysuccinimide with an organic crosslinking agent in an aqueous reaction medium, optionally containing a mineral acid, and then hydrolyzing the crosslinked polysuccinimide to produce a polymeric network of polyaspartate.
Take a look at the above two reactions. Because the first one uses two different types of monomers, one which has two amine groups and one with two acid group, we call this an AA-BB system. Think of the amine groups as As and the acid groups as Bs, and you can figure out why. Likewise, the second reaction, the one using the amino acid, is called an AB system. This is obviously because the monomer contains both an amine group (A) and an acid group (B) in the same molecule. AB systems have an advantage over AA-BB systems. The advantage is that in an AB system, one always has the same amount amine groups and acid groups. As we all know, stoichiometric balance of amine and acid groups is absolutely critical when making nylons. With AA-BB systems, the amounts of the two monomers must be measured very carefully to ensure perfect stoichiometric balance. Interfacial Polymerizations Making nylon 6,6 is even easier if you use a diamine and a diacid chloride instead of a diacid. This is because acid ...

Viscosities of dilute solutions of n-propylamine, n-butylamine, di-n-propylamine, di-n-butylamine, tri-n-propylamine and tri-n-butylamine in toluene, and of tri-n-butylamine in benzene, have been measured at 303.15 K. The values of viscosity deviations are negative for all the amine solutions and their magnitude increases with the increase in concentration of alkylamine. The specific viscosities and excess Gibbs energy of activation of viscous flow, based on Eyrings theory of absolute reaction rates, are of varying magnitude and sign depending upon the viscosities and type and nature of solute and solvent molecules. The specific viscosities have been analyzed in terms of Herskovits and Kelly equation and Nakagawa equation. The change in Gibbs activation energy and the heat of solution per mole of solute (alkylamine) at infinite dilution in cyclohexane, benzene and toluene solutions have been calculated in terms of the transition state theory ...

Article first published online: 8 SEP 2015. LINK. "The CI1 Orgueil meteorite is a highly aqueously altered carbonaceous chondrite. It has been extensively studied, and despite its extensive degree of aqueous alteration and some documented instances of contamination, several indigenous organic compounds including amino acids, carboxylic acids, and nucleobases have been detected in its carbon-rich matrix. We recently developed a novel gas chromatographic method for the enantiomeric and compound-specific isotopic analyses of meteoritic aliphatic monoamines in extracts and have now applied this method to investigate the monoamine content in Orgueil. We detected 12 amines in Orgueil, with concentrations ranging from 1.1 to 332 nmol g−1 of meteorite and compared this amine content in Orgueil with that of the CM2 Murchison meteorite, which experienced less parent-body aqueous alteration. Methylamine is four times more abundant in Orgueil than in Murchison. As with other species, the amine content in ...
A promising architecture for ion-channel mimetics is a composite membrane structure containing vertically aligned carbon nanotubes, with inner core diameters of 7 nm, passing across a polystyrene matrix film. Plasma oxidation during the fabrication process introduces carboxylic acid groups on the CNT tips that are modified using carbodiimide mediated coupling between carboxylic acid on the CNTs and accessible amine groups of the functional molecule. The entrances to CNTs cores were thus functionalized with aliphatic amines of different lengths, charged dye molecule and an aliphatic amine elongated by spacers containing poly-peptides.

Abstract : Aromatic amines and their derivatives are widely used in the production of dyes, cosmetics, medicines and polymers. However, they pose a threat to the environment due to their hazardous wastes as well as their carcinogenic properties. The objective of the study was to use an alternate strategy i.e. biofield energy treatment and analyse its impact on physicochemical properties of aromatic amine derivatives viz. p-phenylenediamine (PPD) and p-toluidine. For this study, both the samples were taken and divided into two parts. One part was considered as control and another part was subjected to Mr. Trivedis biofield treatment. After treatment, both samples were analysed for their physical, thermal and spectral properties as compared to their respective control samples. The analysis was done by using X-ray diffraction (XRD), surface area analyser, thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR), and ultraviolet-visible (UV-Vis) spectroscopy. The XRD studies and surface ...
Researchers at the Georgia Tech Center for Organic Photonics and Electronics (COPE) were presented the Academic R&D Award at IDTechEx Printed Electronics USA, an industry event held in Santa Clara, Calif. on December 10.. COPE won this award after having discovered a universal technique to reduce the work function of a conductor for organic electronics. Using a polymer modifier containing simple aliphatic amine function groups to reduce the work function in a wide range of conductors, including noble metals such as gold (Au) and silver (Ag), conducting polymers, metal oxides, or graphene, air-stable low-work function electrodes were created. These polymers are inexpensive, environmentally friendly, and compatible with existing roll-to-roll mass production techniques. The method is applicable to organic electronic devices including organic solar cells, organic thin-film transistors, and organic light-emitting diodes.. Established in 2003, COPE is a premier national research and educational ...
OBJECTIVE: This study set out to assess the cost effectiveness of using a 5% lidocaine (lignocaine) medicated plaster for the treatment of postherpetic neuralgia (PHN) compared with gabapentin, pregabalin 300 mg/day or 600 mg/day in German primary care. The analysis took the perspective of the Statutory Health Insurance scheme (GKV). METHODS: A Markov model was used to calculate the costs (2007) and benefits of the lidocaine plaster, gabapentin 1800 mg/day and pregabalin 300 or 600 mg/day over a 6-month time horizon in elderly patients with PHN who experienced insufficient pain relief with standard analgesics and could not tolerate or had contraindications to tricyclic antidepressants. The model calculated the cost per quality-adjusted life-year (QALY) gained and the cost per additional month without symptoms or intolerable adverse effects. The majority of transition probabilities were obtained from randomized controlled trials identified from a systematic literature review. Further model inputs,
Low molecular amine names are formed by adding -amine as a suffix to the name of the parent compound. In substitutive nomenclature, the prefix amino- is placed before the name of the parent compound to denote the functional group in high molecular amines. Synthetic amines are made mostly by reaction of alcohols with ammonia, catalyzed by metals( nickel or copper) or metal oxide at high temperature. Many methods have been devised for the synthesis of the amines; reacting ammonia with an alkyl halide and neutralizing the resulting alkyl ammonium salt with an alkali, e.g., sodium hydroxide. This procedure yields a mixture of primary, secondary, and tertiary amines that is easily separated into its three components by fractional distillation; boiling methyl isocyanate with caustic potash, heating the alkyl iodides with ammonia; reduction of nitriles with alcohol and sodium; heating the esters of nitric acid with alcoholic ammonia; reducing on nitro-paraffms; action of zinc and hydrochloric acid ...
Desipramine hydrochloride is a dibenzazepine-derivative tricyclic antidepressant (TCA). TCAs are structurally similar to phenothiazines. They contain a tricyclic ring system with an alkyl amine substituent on the central ring. In non-depressed individuals, desipramine does not affect mood or arousal, but may cause sedation. In depressed individuals, desipramine exerts a positive effect on mood. TCAs are potent inhibitors of serotonin and norepinephrine reuptake. Secondary amine TCAs, such as desipramine and nortriptyline, are more potent inhibitors of norepinephrine reuptake than tertiary amine TCAs, such as amitriptyline and doxepine. TCAs also down-regulate cerebral cortical β-adrenergic receptors and sensitize post-synaptic serotonergic receptors with chronic use. The antidepressant effects of TCAs are thought to be due to an overall increase in serotonergic neurotransmission. TCAs also block histamine-H1 receptors, α1-adrenergic receptors and muscarinic receptors, which accounts for their ...
