Amino acid residues in the transmembrane domain of the type 1 sigma receptor critical for ligand binding. (1/262)

The type 1 sigma receptor expressed in Xenopus oocytes showed binding abilities for the sigma-1 ligands, [3H](+)pentazocine and [3H]NE-100, with similar kinetic properties as observed in native tissue membranes. Amino acid substitutions (Ser99Ala, Tyr103Phe and di-Leu105,106di-Ala) in the transmembrane domain did not alter the expression levels of the type 1 sigma receptor as determined by immunoblot analysis using an anti-type 1 sigma receptor antiserum. By contrast, ligand binding was significantly suppressed by the substitutions. These findings provide evidence that the transmembrane domain of the type 1 sigma receptor plays a critical role in ligand binding of this receptor.  (+info)

A-Current down-modulated by sigma receptor in frog pituitary melanotrope cells through a G protein-dependent pathway. (2/262)

Gramicidin perforated patch-clamp recordings were used to study the effects of two sigma 1 receptor ligands, (+)-N-cyclopropylmethyl-N-methyl-1, 4-diphenyl-1-ethyl-but-3-en-1-ylamine hydrochloride (JO 1784) and (+)-pentazocine, on the transient outward potassium current (IA) in cultured frog melanotrope cells. (+)-Pentazocine reversibly decreased the current amplitude in a dose-dependent manner. The effects of (+)-pentazocine were mimicked by JO 1784 and were markedly reduced by the sigma 1 receptor antagonist, N, N-dipropyl-2-[4-methoxy-3-2(2-phenylethoxy)phenyl]-ethylamine monohydrochloride (NE 100). Inactivation rate of IA was best fitted with a double exponential function, yielding time constants of 23.7 and 112.5 ms. (+)-Pentazocine (20 microM) accelerated the current decay, decreasing the time constants to 10.7 and 59 ms, respectively. Current-voltage experiments revealed that (+)-pentazocine (20 microM) did neither modify the open-state I/V curves nor the voltage dependence of IA. However, (+)-pentazocine (20 microM) shifted the steady-state inactivation curve toward more negative potentials and increased the time constant of the time-dependent removal of inactivation. In whole-cell experiments, internal dialysis of guanosine-5'-O-(3-thiophosphate) (100 microM) irreversibly prolonged the response to (+)-pentazocine. In addition, cholera toxin pretreatment (1 microgram. ml-1; 12 h) suppressed the inhibition of IA by (+)-pentazocine (20 microM). It is concluded that in frog melanotrope cells, a cholera toxin-sensitive, G protein-dependent inhibition of IA through a sigma 1 receptor activation, at least partially, underlies the excitatory effect of sigma ligands.  (+info)

Sigma1 recognition sites in rabbit iris-ciliary body: topical sigma1-site agonists lower intraocular pressure. (3/262)

In this study, we examined the presence of sigma1 and sigma2 sites in the rabbit iris-ciliary body by receptor binding and investigated their effects on intraocular pressure (IOP) in albino rabbits. The iris-ciliary body has binding sites for the sigma1-site agonist [3H](+)-pentazocine (Kd = 4.6 nM; Bmax = 212 fmol/mg protein) and sigma2 sites labeled with [3H]1,3-di-o-tolylguanidine (DTG) (Kd = 8. 2 nM; Bmax = 1120 fmol/mg protein). In competition binding studies, (+)-pentazocine and the sigma antagonist NE-100 displayed high affinity for sigma1 sites (Ki = 2.1 and 2.4 nM, respectively), whereas (+)-N-allylnormetazocine (NANM) was less potent (Ki = 178 nM). Unilateral topical (+)-pentazocine (0.01-0.1%) caused a significant dose-related reduction of IOP in ocular normotensive rabbits and in the alpha-chymotrypsin model of ocular hypertension. (+)-NANM was less potent than (+)-pentazocine. Neither compound altered the IOP of the contralateral eye, and their hypotensive activity was blocked by NE-100 that, by itself, had no effect on IOP. (-)-Pentazocine, (-)-NANM, and DTG had no effect on IOP. DTG prevented the hypotensive effect of (+)-pentazocine, suggesting that it acts as a sigma1-site antagonist. sigma-Site ligands did not affect pupil diameter or cause ocular inflammation. Topical [3H](+)-pentazocine reaches the intraocular tissues within 30 min, and its uptake in the iris-ciliary body and retina was significantly reduced by topical pretreatment with NE-100, as expected for a receptor-specific agent. Reverse-phase HPLC confirmed the presence of intact (+)-pentazocine in iris-ciliary body homogenates. sigma1-Site agonists may offer a novel class of agents potentially effective in the control of ocular hypertension.  (+info)

Mechanism-based inactivation of rat liver cytochrome P-450 2B1 by 2-methoxy-5-nitrobenzyl bromide. (4/262)

Mechanism-based inactivators serve as probes of enzyme mechanism, function, and structure. Koshland's Reagent II (2-methoxy-5-nitrobenzyl bromide, KR-II) is a potential mechanism-based inactivator of enzymes that perform O-dealkylations. The major phenobarbital-inducible form of cytochrome P-450 in male rat liver microsomes, CYP2B1, is capable of catalyzing O-dealkylations. The interactions of KR-II with purified CYP2B1 in the reconstituted system containing P-450, NADPH:P-450 oxidoreductase, and sonicated dilaurylphosphatidyl choline were studied. The benzphetamine N-demethylase activity of CYP2B1 was inactivated by KR-II in a time- and NADPH-dependent manner, and the loss of activity followed pseudo-first-order kinetics. The inactivation also required KR-II, and the rate of activity loss was dependent on the concentration of KR-II in a saturable fashion. The inactivator concentration required for the half-maximal rate of inactivation (KI) was approximately 0.1 mM. The inactivation was not prevented by the addition of the nucleophiles dithiothreitol and glutathione, nor was it reversed by gel filtration. The present results demonstrate that KR-II is a mechanism-based inactivator of rat CYP2B1.  (+info)

Odor response properties of rat olfactory receptor neurons. (5/262)

Molecular biology studies of olfaction have identified a multigene family of molecular receptors that are likely to be involved in odor transduction mechanisms. However, because previous functional data on peripheral coding were mainly collected from inferior vertebrates, it has been difficult to document the degree of specificity of odor interaction mechanisms. As a matter of fact, studies of the functional expression of olfactory receptors have not demonstrated the low or high specificity of olfactory receptors. In this study, the selectivity of olfactory receptor neurons was investigated in the rat at the cellular level under physiological conditions by unitary extracellular recordings. Individual olfactory receptor neurons were broadly responsive to qualitatively distinct odor compounds. We conclude that peripheral coding is based on activated arrays of olfactory receptor cells with overlapping tuning profiles.  (+info)

New studies on trans-anethole oxide and trans-asarone oxide. (6/262)

The widespread use of naturally occurring alkenylbenzenes as flavoring and fragrance agents has led to a long-standing interest in their toxicity and carcinogenicity. Among them several allyl- and propenylbenzenes have been found to be mutagenic and carcinogenic. It has been shown that the carcinogenicity of several allylbenzenes can be related to the formation of electrophilic sulfuric acid esters following 1'-hydroxylation. Unlike the allylbenzenes, the mechanisms of carcinogenesis of propenylbenzenes such as anethole and asarone are not clear. It has been reported that one of the main metabolic pathways of trans-anethole is the epoxidation of the side chain 1,2-double bond, which was responsible for cytotoxicity but not for genotoxicity. However, we report here that synthetic trans-anethole oxide prepared from trans-anethole and dimethyldioxirane is not only mutagenic for Salmonella tester strains but is also carcinogenic in the induction of hepatomas in B6C3F1 mice and skin papillomas in CD-1 mice. Synthetic trans-asarone oxide was also carcinogenic in the induction of hepatomas as well as mutagenic for Salmonella strains. Further studies are needed on these side chain oxides of trans-anethole and trans-asarone as possible metabolites in the toxicity, mutagenicity and carcinogenicity of these and other propenylbenzenes.  (+info)

Dose-response trend tests for tumorigenesis, adjusted for body weight. (7/262)

Several studies have demonstrated a relationship between rodent body weight and tumor incidence for some tissue/organ sites. It is not uncommon for a chemical tested for carcinogenicity to also affect body weight. In such cases, comparisons of tumor incidence may be biased by body-weight differences across dose groups. A simple procedure was investigated for reducing this bias. This procedure divides the animals into a few groups based on body weight. Body weight at 12 months was used, before the appearance of a tumor was likely to affect body weight. Statistics for dose-response trend tests are calculated within body weight strata and pooled to obtain an overall dose-response trend test. This procedure is analogous to that currently used, of stratifying animals, based on their age at the time of removal from a study. Age stratification is used to account for differences in animal age across dose groups, which can affect comparisons of tumor incidence. Several examples were investigated where the high-dose group had reduced body weights and associated reductions in tumor incidence. When the data were analyzed by body-weight strata, some positive dose-response trends for tumor incidence were demonstrated. In one case, the weight-adjusted analysis indicated that a negative dose-response trend in tumor incidence was a real effect, in addition to a body weight reduction. These examples indicate that it is important to consider the effects of body weight changes as low as 10%, and perhaps below, that were caused by chemicals in 2-year bioassays for carcinogenesis. The simple procedure of analyzing tumor incidence within body-weight strata can reduce the bias introduced by weight differences across dose groups.  (+info)

Induction of apoptosis in leukemic cells by the reversible microtubule-disrupting agent 2-methoxy-5-(2',3',4'-trimethoxyphenyl)-2,4,6-cycloheptatrien-1 -one: protection by Bcl-2 and Bcl-X(L) and cell cycle arrest. (8/262)

We have found that the bicyclic colchicine analogue 2-methoxy-5-(2',3',4'-trimethoxyphenyl)-2,4,6-cycloheptatrien-1-on e (MTC) induced a dose- and time-dependent apoptotic response in human leukemic cells. MTC and colchicine rapidly disrupted the microtubule integrity and arrested cells at the G2-M phase before the onset of apoptosis. These responses were mediated by microtubule inhibition because 2-methoxy-5-[[3-(3,4,5-trimethoxyphenyl)propionyl]amino]-2,4,6-cycloh eptatrien-1-one and lumicolchicine, inactive analogues of MTC and colchicine, respectively, were unable to promote microtubule disassembly, cell cycle arrest, and apoptosis. Although 1 microM MTC induced a complete microtubule disruption after 1 h of incubation in human leukemic HL-60 cells that led to an accumulation of cells at the G2-M phase, MTC-induced apoptosis occurred after 9 h of treatment. This indicates the existence of a rather long lag between microtubule disruption and the onset of apoptosis. Unlike colchicine, the removal of MTC during this lag resulted in rapid microtubule repolymerization, followed by restoration of normal cell cycle and cell growth. MTC, but not 2-methoxy-5-[[3-(3,4,5-trimethoxyphenyl)-propionyl]amino]-2,4,6-cyclo heptatrien-1-one, induced c-jun expression as well as c-Jun NH2-terminal kinase and caspase activation, indicating that these signaling pathways are triggered by the specific action of MTC on microtubules. Caspase inhibition prevented MTC-induced apoptosis. Overexpression of bcl-2 or bcl-xL by gene transfer in human erythroleukemic HEL cells abrogated MTC-induced apoptosis, but cells remained arrested in G2-M, suggesting that bcl-2 and bcl-xL block the signaling pathway between G2-M arrest and triggering of apoptosis. MTC-treated bcl-2 and bcl-xL-transfected HEL cells recovered their capacity to proliferate after MTC removal. These results indicate that microtubule inhibition induces G2-M arrest and apoptosis in leukemic cells, showing a lag phase between G2-M arrest and the onset of apoptosis, regulated by bcl-2 and bcl-xL, during which MTC displays a reversible action on microtubule depolymerization and G2-M cell cycle arrest. Thus, MTC is a potent apoptotic inducer on human leukemic cells and shows a remarkable reversible action on microtubule network and cell cycle before commitment for apoptosis is reached.  (+info)

TY - JOUR. T1 - Alkali-metal-mediated zincation of anisole: synthesis and structures of three instructive ortho-zincated complexes. AU - Clegg, W AU - Dale, S H AU - Drummond, A M AU - Hevia, E AU - Honeyman, G W AU - Mulvey, R E PY - 2006/6/14. Y1 - 2006/6/14. N2 - The new concept of alkali-metal-mediated zincation (AMMZ), formally a zinc−hydrogen exchange reaction but one that requires the participation of an alkali metal, is applied here to the alkyl aryl ether anisole, an important molecule for studying directed ortho-metalation (DoM) chemistry. Treating one molar equivalent of anisole with the lithium dialkyl-TMP zincate reagent [THF·Li(μ-TMP)(μ-tBu)Zn(tBu)] (1) in hexane solution affords the mono-ortho-zincated complex [THF·Li(μ-TMP)(μ-o-C6H4OMe)Zn(tBu)] (2), which establishes that 1 functions as an alkyl base although previously it was regarded as an amido (TMP) base in other DoM applications. Treating two molar equivalents of anisole with 1, and increasing the reaction time, ...
Abstract : The objective of the present study was to evaluate the impact of biofield energy treatment on the thermal,spectroscopic, and chemical properties of anisole by various analytical methods such as gas chromatography-massspectrometry (GC-MS), high performance liquid chromatography (HPLC), differential scanning calorimetry (DSC),Fourier transform infrared (FT-IR) spectroscopy, and ultraviolet-visible (UV-Vis) spectroscopy. The anisole sample wasdivided into two parts, control and treated. The control part was remained same while the other part was treated withMr. Trivedis unique biofield energy treatment. Mass spectra showed the molecular ion peak with five fragmented peaksin control and all treated samples. The isotopic abundance ratio of 2H/1H, and 13C/12C [(PM+1)/PM] in treated samplewas increased by 154.47% (T1) as compared to the control [where, PM- primary molecule, (PM+1)-isotopic moleculeeither for 13C or 2H]. The HPLC chromatogram showed retention time of treated anisole was ...

I dont think polarization is the issue. Adding $\ce{FeBr3}$ is just to reduce the $\ce{Br-Br}$ bond strength, speeding up the reaction (attack of the aromatic ring on the bromine is part of the rate determining step, which is slow in the bromination of benzene). It functions as a catalyst being recycled when the $\ce{Br-}$ grabs a $\ce{H+}$ to restore aromaticity in the ring. Im pretty sure - at least I see no reason to doubt - that the catalyst requirements for the bromination of anisole and the bromination of phenol do not differ much, if at all. That is, no catalyst is required for the bromination of anisole.. ...

Estragole is suspected to be carcinogenic and genotoxic, as is indicated by a report of the European Union, Committee on Herbal Medicinal Products.[3] Several studies have clearly established that the profiles of metabolism, metabolic activation, and covalent binding are dose dependent and that the relative importance diminishes markedly at low levels of exposure (i.e. these events are not linear with respect to dose). In particular, rodent studies show that these events are minimal probably in the dose range of 1-10 mg/kg body weight, which is approximately 100-1000 times the anticipated human exposure to this substance. For these reasons it is concluded that the present exposure to estragole resulting from consumption of herbal medicinal products (short time use in adults at recommended posology) does not pose a significant cancer risk. In the meantime exposure of estragole to sensitive groups such as young children, pregnant and breastfeeding women should be minimized. The Scientific ...
First order-like plots, due to the large excess of methoxide, are obtained in each case, except with methyl benzoate (Plot 3) where metallic copper appeared after 1 hour (decomposition of catalyst). Slope ratio between the blank experiment (Plot 1) and the ethyl acetate one (Plot 6) is superior to 20, demonstrating the effectiveness of this co-catalyst (completion is reached within 45 min., with a quasi-quantitative yield).. Use of ethyl rather than methyl esters leads sometimes to traces of 2-ethoxy phenol (0.5 to 1%), due to releasing of ethoxide ion through transesterification of the co-catalyst by methoxide; methyl esters may therefore be preferred if highest purity of final product is required.. Anisole is also quasi-quantitatively obtained from bromobenzene in presence of ethyl acetate (10 mmole PhBr, 4 mmol EtOAc, 1,4 mmol CuBr in 6 ml 5M MeONa/MeOH, 98% conversion after 1h reflux, 100% after 2h, yield of isolated anisole >95% without detected phenetole)..

This compound tends to aggregate into one-dimensional direction, resulting in an organogel phase in anisole and diphenyl ether solvents. The gel can be formed even at 0.125 wt/vol% in anisole and the sol-gel phase transition temperatures (Tgel) are as high as 120-140°C, indicating that 1b acts as an excellent gelator for these specific solvents. The spectroscopic studies and electron-micrographic observations support the view that the π-π stacking interaction among porphyrin moieties and the hydrogen-bonding interaction among urea moieties operate synergistically to give rise to a stable one-dimensional ...

We have studied the pyrolysis of aromatic combustion intermediates using an array of detection techniques. The molecules investigated include cyclic aromatic molecules with hydrocarbon substituents (ethylbenzene, n-propylbenzene, isopropylbenzene, and styrene), oxygen-containing substituents (anisole and phenol), triply substituted systems (vanillin), resonance stabilized radicals (benzyl radical and tropyl radical) and phenyl radical. At the exit of a resistively heated micro-reactor (1 mm inner diameter, 3 cm long), the pyrolysis fragments are detected using photoionization mass spectrometry (PIMS), matrix isolation vibrational spectroscopy, microwave spectroscopy, tunable VUV synchrotron-based PIMS, and table-top VUV PIMS with photoelectron photoion coincidence spectroscopy (PEPICO). This array of detection methods allows for the identification of all possible fragments including metastables, radicals, and atoms. The findings allow for detailed mechanistic information regarding which pathways ...
Lawessons reagent (full name 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane 2,4-disulfide (or -disulphide) is a chemical compound with the formula C14H14O2P2S4, used in organic synthesis as a thiation (also called thionation or sulfuration) agent. This light yellow to beige powder has a strong and unpleasant odour.. Lawessons reagent was first produced in 1956 during a systematic study of the reactions of arenes with the comparable reagent P4S10. However it was Swedish chemist Sven-Olov Lawesson who popularized Lawessons reagent within the chemical community.. Being commercially available, Lawessons reagent can also be conveniently made in the laboratory by heating a mixture of anisole with phosphorus pentasulfide until the mixture is clear and no more hydrogen sulfide is formed, and then recrystallized from toluene or xylene.. The main application of Lawessons reagent is the thionation of carbonyl compounds - the carbonyl group is converted into thiocarbonyl group, carbon-oxygen ...

The cell wall protein peptidoglycan complex (CW-PPC) ofMycobacterium tuberculosis H37Ra was isolated through sequential extraction of lipids, carbohydrates and soluble proteins. CW-PPC emulsified in FIA was found to induce significant protection in mice against challenge with LD50 dose ofM. tuberculosis H37Rv. To identify the immunoprotective components of CW-PPC, the proteins in avid association with peptidogican were dissociated by chemical treatment with trifluoromethanesulthonic acid (CF3CO3H): anisole (2:1). Immunoreactivity of total (CW-Pr) as well as its component proteins i.e., 71, 60 and 45 kDa proteins of cell wall was studied in animals immunized with CW-Pr-FIA. The 71 kDa protein was found to be most immunoreactive giving higher T-cell sensitization and humoral responses. Further, immunization of mice with 71 kDa-FIA demonstrated enhanced T- and B- cell responses. Mice immunized with 71 kDa-FIA gave significantly higher protection (P ≤ 0.05) against intravenous challenge with LD50 ...

A metabolite of beta-asarone is the reason Acurus calamus is known in some cultures as a psychedelic. However, not all Acorus calamus contains sufficient quantities of beta-asarone to be effective. Acorus calamus from Nepal typically contains a large amount of beta-asarone. Acorus calamus from India usually contains very little beta-asarone, and will cause extreme nausea before doses high enough to get some minor effects from beta-asarone are ingested.. Its important to note that beta-asarone itself is not active. One of its metabolites can produce psychedelic effects in man. Not everyones body metabolizes beta-asarone the same way, leading to different results for different individuals. Some people are not able to experience psychedelic effects from ingesting beta-asarone. This is because their bodies do not produce enough of the active metabolite to experience effects.. The active metabolite of beta-asarone is currently unidentified. There has been speculation of it being an amphetamine, ...
Therapeutic properties:. Below are a few therapeutic properties that research studies have shown regarding Trans-anethole ((E)-anethole). Please keep in mind these are for the specific chemical component and may not be representative of the entire essential oil it is found in depending on the percentages shown in gas chromatography and mass spectronomy analysis..

Antifungal: anethole has been shown to exhibit synergistic antifungal activity against a budding yeast3 and candida6. Anti-inflammatory: (E)-Anethole blocks cellular responses induced by Tumor Necrosis Factor indicating an anti-inflammatory action4 (TNF is a chemical messenger that induces cell death. TNF is directed at abnormal cells to assist in preventing the formation of tumors.). There was a study also that showed anethole to be a potential candidate in supporting the restoration of functional dyspepsia.5. Balanced use:. It is important to ...
We have shown previously that low doses of selective sigma (sigma)- receptor ligands potentiate the excitatory response of pyramidal neurons to NMDA in the CA3 region of the dorsal hippocampus in the rat. Because progesterone competitively displaces the binding of the ligand N-[3H]allyl-normetazocine (SKF-10,047), the present studies were undertaken to determine in vivo the effect of neuroactive steroids on NMDA-induced excitation of rat CA3 pyramidal neurons. Low doses of dehydroepiandrosterone (DHEA) potentiated the NMDA response selectively and dose-dependently. The effect of DHEA was reversed by the selective sigma antagonist N-dipropyl-2-(4-methoxy-3- (2-phenylethoxy)phenyl)- ethylamine monohydrochloride (NE-100) and by haloperidol, but not by spiperone. Progesterone had no effect by itself but reversed, at low doses, the potentiation of the NMDA response induced by DHEA as well as those induced by nonsteroidal sigma ligands. Neither pregnenolone nor pregnenolone sulfate had any effect on ...

1-Methoxy-4-(2-propenyl)benzene, also known as methylchavicol or estragol, belongs to the class of organic compounds known as anisoles. These are organic compounds containing a methoxybenzene or a derivative thereof. 1-Methoxy-4-(2-propenyl)benzene is an extremely weak basic (essentially neutral) compound (based on its pKa). 1-Methoxy-4-(2-propenyl)benzene is a sweet, alcohol, and anise tasting compound. Outside of the human body, 1-Methoxy-4-(2-propenyl)benzene is found, on average, in the highest concentration within a few different foods, such as anises, fennels, and sweet basils and in a lower concentration in cumins, tarragons, and parsley. 1-Methoxy-4-(2-propenyl)benzene has also been detected, but not quantified in, several different foods, such as citrus, chinese cinnamons, caraway, fats and oils, and cloves. This could make 1-methoxy-4-(2-propenyl)benzene a potential biomarker for the consumption of these foods. 1-Methoxy-4-(2-propenyl)benzene, with regard to humans, has been linked to ...

Ischemic hypoxic brain injury often causes irreversible brain damage. The lack of effective and widely applicable pharmacological treatments for ischemic stroke patients may explain a growing interest in traditional medicines. β-Asarone, which has significant pharmacological effects on the central nervous system (CNS), was used in the prevention of cerebral ischemia in this paper. The right middle cerebral artery occlusion model was used in the study. The effects of β-Asarone on mortality rate, neurobehavior, grip strength, lactate dehydrogenase, glutathione content, Lipid peroxidation, glutathione peroxidase activity, glutathione reductase activity, catalase activity, Na+-K+-ATPase activity and glutathione S transferase activity in a rat model were studied respectively. β-Asarone significantly improved the neurological outcome after cerebral ischemia and reperfusion in terms of neurobehavioral function in rats. Meanwhile, supplementation of β-Asarone significantly boosted the defense mechanism

Most of the ADCs currently in the market and in clinical development carry tubulin polymerization inhibitors such as T-DM1 and SGN-35 (Brentuximab vedotin; ref. 13). We synthesized a novel ADC with a topoisomerase I inhibitor, which has a different mechanism of action from tubulin polymerization inhibitors, and a novel self-immolative linker system using an aminomethylene (AM) moiety. Although other cleavable linker systems applied to SGN-35 (Brentuximab vedotin) and several ADCs release amino group-containing payloads, this AM self-immolative linker system is able to release DXd containing the hydroxyl group from DS-8201a. Moreover, this novel linker-payload system enables a reduction in the hydrophobicity of the ADC and helps increase its DAR. In the case of T-DM1, lysine conjugation and noncleavable systems are used, and it is quite a different system from DS-8201a. DS-8201a showed potent HER2-specific efficacy both in vitro and in vivo, and by drug conjugation maintained the functional ...

N2 - The development of new antiarrhythmic agents for the treatment of atrial fibrillation is advancing simultaneously on several fronts. The molecular structure of existing agents such as amiodarone is being modified in an attempt to improve safety and reduce adverse effects. Similarly, atrial-selective antiarrhythmic drugs are being developed to minimize the occurrence of ventricular proarrhythmia. One of these atrial-selective compounds is vernakalant, which has demonstrated efficacy in terminating atrial fibrillation when given intravenously. In addition, preliminary data suggest that it could also suppress recurrences when used orally. This paper reviews the pharmacology, electrophysiology, efficacy ...
The authors of the AVRO study also assert that, while both treatments were found to be safe and well tolerated, vernakalant had low proarrhythmic potential and provides a rapidly acting therapeutic alternative.. The research team, led by Professor John Camm from St. Georges University of London, conducted a randomized, double-blind, multicenter superiority trial in 254 adult patients with underlying cardiovascular disease, making certain antiarrhythmic drugs inappropriate for use. 116 patients in each group received at least one dose of the study drug. Approximately 30% of patients in both treatment arms had no AF episodes prior to the initial diagnosis, whereas one-third had at least three.. Those in the vernakalant study arm received a 10-minute infusion of 3 mg/kg followed by an additional 10-minute infusion of 2 mg/kg if needed after a 15-minute observation period. Amiodarone patients received a 60-minute infusion of 5 mg/kg followed by an additional 60-minute maintenance infusion of 50 ...

The first indication in determining the quality of wine is if there is presence of any faults. The more common ones include cork taint (TCA) and oxidation and can be detected when an aroma or flavor in the wine appears off or just wrong. Cork taint occurs when 2,4,6 - Tricloranisole or TCA, generated by naturally-occurring fungi that often exist in the crevices of wood or cork, comes into contact with chlorine compounds present in pesticides, cleaning agents, wood treatments, etc. When cork taint occurs, the wine will have a musty, moldy aroma. Controlling the source of TCA has proven extremely difficult and currently there are no solutions.. Another wine fault is the oxidation or reduction of the wine - which happens when wines are either exposed to too much or too little oxygen respectively. When oxidation occurs, this usually results in a breakdown of its attractive color. Whites go a dull brown/straw, rosés go brown/orange, reds become paler with an orange/brown rim. Chilling grapes and ...
The present study reports densities (ρ), viscosities (η) and ultrasonic speeds (U) of pure dioxane (DOX), anisole (ANS), toluene (TOL) and ethylbenzene (ETB) and their binary liquid mixtures over the entire composition range at 293, 298, 303, 308 and 313 K. From the experimental data excess molar volume (VmE), excess intermolecular free length (LfE), excess adiabatic compressibility (βE) and excess acoustic impedance (ZE) have been computed. The excess values were correlated using Redlitch-Kister polynomial equation to obtain their coefficients and standard deviations (σ). With increase in temperature, the binary mixture of DOX+ANS shows larger deviations in βE, LfE and smaller deviations in ZE, VmE. These results suggest that ANS has strong molecular interactions with DOX than ETB and TOL.

Many would argue that the sense of smell is our far most important sense when it comes to evaluating wine. This is because the olfactory sense plays a fundamental role both in the perception of aroma and also flavour. Without it all wines,3 rather than just a few, would appear to be uninteresting alcoholic solutions of acid and sugar. The sense of smell is by far the most powerful of our senses. It can discriminate between tens of thousands of different aromas, and is capable of detecting some compounds found in wine at levels around a single part per trillion. An example of this is the compound 2,4,6 Trichloroanisole, the primary compound responsible for cork taint. Some people can detect it at around 1 part per trillion which is analogous to a single second in thirty two years. Not bad I suppose, but when you think that an Alsatian or Beagle probably sees a three dimensional colliedescope like scent world, our olfactory efforts seem pretty pathetic in comparison. The olfactory system ...

The test item consisted of non-transparent particles which had a very strong tendency for agglomeration. The particles had a sticky behaviour and were electrostatically charged after sieving. A large part of the test item was present in form of agglomerates with a diameter above 1 mm. The aforementioned effects opposed a measurement via sieve analysis and influenced the results of the study using laser diffraction. Hence, the test item was sieved with a mesh size of 1000 µm. Only 43% (w/w) of the test item passed the sieve and only this fraction was measured with laser diffraction.
