Propachlor removal by Pseudomonas strain GCH1 in an immobilized-cell system. (1/292)

A bacterial strain capable of growing on propachlor (2-chloro-N-isopropylacetanilide) was isolated from soil by using enrichment and isolation techniques. The strain isolated, designated GCH1, was classified as a member of the genus Pseudomonas. Washed-cell suspensions of strain GCH1 accumulated N-isopropylacetanilide, acetanilide, acetamide, and catechol. Pseudomonas strain GCH1 grew on propachlor with a generation time of 4.2 h and a rate of substrate utilization of 1.75 +/- 0.15 micromol h(-1). Gene expression did not require induction but was subject to catabolite expression. Acetanilide was a growth substrate with a yield of 0.56 +/- 0.02 mg of protein micromol(-1). GCH1 strain cells were immobilized by adsorption onto a ceramic support and were used as biocatalysts in an immobilized cell system. Propachlor elimination reached 98%, with a retention time of 3 h and an initial organic load of 0.5 mM propachlor. The viability of immobilized cells increased 34-fold after 120 days of bioreactor operation.  (+info)

Acute metobromuron poisoning with severe associated methemoglobinemia. Identification of four metabolites in plasma and urine by LC-DAD, LC-ESI-MS, and LC-ESI-MS-MS. (2/292)

A case of self poisoning with metobromuron, a urea derivative used as a herbicide, is reported. Severe methemoglobinemia observed at the admission (80%) disappeared only at day 11, and hemolysis appeared at day 4 and decreased slowly to day 12. Metobromuron was analyzed by liquid chromatography with diode-array detection. Initial plasma concentration and elimination half-life were 4.9 mg/L and 5 h, respectively. Several metabolites were also detected, and four of those were identified by liquid chromatography-electrospray mass spectrometry. Normetobromuron, bromophenylurea, and bromoacetanilide were detected in plasma, but only N-methyl bromophenylurea was detected in urine. Bromoacetanilide probably results from acetylation of the intermediate bromoaniline. Methemoglobinemia could result from metabolization of metobromuron to bromoaniline and bromoacetanilide.  (+info)

Comparative metabolism of chloroacetamide herbicides and selected metabolites in human and rat liver microsomes. (3/292)

Acetochlor [2-chloro-N-(ethoxymethyl)-N-(2-ethyl-6-methyl-phenyl)-acetamide], alachlor [N-(methoxymethyl)-2-chloro-N-(2, 6-diethyl-phenyl)acetamide], butachlor [N-(butoxymethyl)-2-chloro-N-(2,6-diethyl-phenyl)acetamide], and metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl) acetamide] are pre-emergent herbicides used in the production of agricultural crops. These herbicides are carcinogenic in rats: acetochlor and alachlor cause tumors in the nasal turbinates, butachlor causes stomach tumors, and metolachlor causes liver tumors. It has been suggested that the carcinogenicity of these compounds involves a complex metabolic activation pathway leading to a DNA-reactive dialkylbenzoquinone imine. Important intermediates in this pathway are 2-chloro-N-(2,6-diethylphenyl)acetamide (CDEPA) produced from alachlor and butachlor and 2-chloro-N-(2-methyl-6-ethylphenyl)acetamide (CMEPA) produced from acetochlor and metolachlor. Subsequent metabolism of CDEPA and CMEPA produces 2,6-diethylaniline (DEA) and 2-methyl-6-ethylaniline (MEA), which are bioactivated through para-hydroxylation and subsequent oxidation to the proposed carcinogenic product dialkylbenzoquinone imine. The current study extends our earlier studies with alachlor and demonstrates that rat liver microsomes metabolize acetochlor and metolachlor to CMEPA (0.065 nmol/min/mg and 0.0133 nmol/min/mg, respectively), whereas human liver microsomes can metabolize only acetochlor to CMEPA (0.023 nmol/min/mg). Butachlor is metabolized to CDEPA to a much greater extent by rat liver microsomes (0.045 nmol/min/mg) than by human liver microsomes (< 0.001 nmol/min/mg). We have determined that both rat and human livers metabolize both CMEPA to MEA (0.308 nmol/min/mg and 0.541 nmol/min/mg, respectively) and CDEPA to DEA (0.350 nmol/min/mg and 0.841 nmol/min/mg, respectively). We have shown that both rat and human liver microsomes metabolize MEA (0.035 nmol/min/mg and 0.069 nmol/min/mg, respectively) and DEA (0.041 nmol/min/mg and 0.040 nmol/min/mg, respectively). We have also shown that the cytochrome P450 isoforms responsible for human metabolism of acetochlor, butachlor, and metolachlor are CYP3A4 and CYP2B6.  (+info)

Etidocaine, bupivacaine, and lidocaine seizure thresholds in monkeys. (4/292)

The central nervous system toxicities of etidocaine, bupivacaine, and lidocaine were studied during constant-rate intravenous infusions in rhesus monkeys. Comparison of drug effects was achieved by determining the drug dosages and arterial plasma concentrations that induced electrical seizure activity. The central nervous system toxicity of etidocaine was similar to that of bupivacaine. The toxicity of each was four times greater than that of lidocaine. Since the drug infusion rates were proportional to anesthetic potencies in clinical usage, the therapeutic-toxic ratios of these three drugs are similar.  (+info)

Isolation of an inducible amidase from Pseudomonas acidovorans AE1. (5/292)

A bacterial strain, AEI, which hydrolysed acetanilide, was isolated from soil and identified as Pseudomonas acidovorans. Numerous amides, esters and enzyme inhibitors were tested as amidase inducers. Phenacetin was chosen as inducer for the large scale cultivation of these organisms because it was less toxic to the bacteria than acetanilide. The induction increased the enzymic activity 250-fold. In comparison, the type culture strain of P. acidovorans, ATTCCI5668, had no amidase activity which could be induced by phenacetin. Optimal growth conditions were established with respect to the concentration of carbon source and inducer so that about 10% of the extractable bacterial protein consisted of the amidase. The organisms were lysed with lysozyme in the presence of EDTA and the enzyme was isolated mainly by column chromatography procedures. A preparation form 60 g (wet wt) bacteria yielded about 100 mg highly purified amidase with a specific activity of 137 mugmol substrate hydrolysed/min/mg protien. In addition to acetanilide, the purified enzyme hydrolysed several other amides and esters. As standard substrate, p-nitroacetanilide was chosen.  (+info)

Application of the PKCYP-test in cases of altered CYP1A2 for multiple CYP systems in rat models of disease. (6/292)

Previously, we established a method to assess drug metabolism capacity based on a pharmacokinetic estimation of the quantity of cytochrome P450 (CYP) in vivo (PKCYP-test) by introducing an apparent liver-to-blood free concentration gradient in vivo (qg). The qg values were determined as the ratio of in vivo-in vitro clearance. In this study, we examined the application of the PKCYP-test to the clearance of acetanilide and caffeine mediated by CYP1A2 using rat models in which the levels of CYP enzymes were reduced. Rats fed a choline-deficient diet (CD-fed) and aged rats were used as models for a low level of CYP in the liver. In both rat models, the contribution (fCYP) of CYP1A2 to the in vivo intrinsic clearance values (CLint) of acetanilide and caffeine metabolism was less than unity, suggesting that other metabolic pathways are involved in the CLint. The in vivo clearance for CYP1A2 was estimated by multiplying fCYP by CLint, then the value of qg was determined as the ratio of in vivo-in vitro clearance. We predicted the level of CYP1A2 in CD-fed and aged rats, based on the clearance of acetanilide mediated by CYP1A2, using the qg value of control rats. The clearance of caffeine mediated by CYP1A2 in CD-fed and aged rats, as estimated from the predicted level of CYP1A2, correlated with the observed values. In conclusion, we have demonstrated that the PKCYP-test can be applied to CYP1A2 for drugs metabolized by multiple CYP isozymes, and/or to models involving reduced CYP.  (+info)

Acetaminophen induces apoptosis of C6 glioma cells by activating the c-Jun NH(2)-terminal protein kinase-related cell death pathway. (7/292)

Acetaminophen (AAP), a widely used analgesic drug, can damage various organs when taken in large doses. In this study, we investigate whether AAP causes cell damage by altering the early signaling pathways associated with cell death and survival. AAP caused time- and concentration-dependent apoptosis and DNA fragmentation of C6 glioma cells used as a model. AAP activated c-Jun N-terminal protein kinase (JNK) by 5.3-fold within 15 min. The elevated JNK activity persisted for up to 4 h before it returned to the basal level at 8 h. In contrast, activities of other mitogen-activated protein (MAP) kinases and the level of Akt phosphorylation in the cell survival pathway remained unchanged throughout the treatment. Wortmannin, an inhibitor of phosphatidylinositol-3 kinase, or SB203580, an inhibitor of p38 MAP kinase, did not reduce AAP-induced toxicity, indicating that these enzymes do not play a major role in cell toxicity. AAP-induced apoptosis was preceded by the sequential elevation of the pro-apoptotic Bax protein, cytochrome c release, and caspase-3 activity. Treatment with caspase inhibitor benzyloxycarbonyl-Asp-Glu-Val-Asp-fluoromethyl ketone (Z-DEVD-FMK) significantly reduced AAP-induced caspase-3 activation and cytotoxicity. Transfection of cDNA for the dominant-negative mutant JNK-KR or stress-activated protein kinase kinase-1 Lys-->Arg mutant (SEK1-KR), an immediate upstream kinase of JNK, significantly reduced AAP-induced JNK activation and cell death rate. The noncytotoxic analog of AAP, 3-hydroxyacetanilide, neither increased JNK activity nor caused apoptosis. Pretreatment with YH439, an inhibitor of CYP2E1 gene transcription, markedly reduced CYP2E1 mRNA, protein content, and activity, as well as the rate of AAP-induced JNK activation and cell death. These data indicate that AAP can cause cell damage by activating the JNK-related cell death pathway, providing a new mechanism for AAP-induced cytotoxicity.  (+info)

Posttranslational modification of the umuD-encoded subunit of Escherichia coli DNA polymerase V regulates its interactions with the beta processivity clamp. (8/292)

The Escherichia coli umuDC (pol V) gene products participate in both a DNA damage checkpoint control and translesion DNA synthesis. Interactions of the two umuD gene products, the 139-aa UmuD and the 115-aa UmuD' proteins, with components of the replicative DNA polymerase (pol III), are important for determining which biological role the umuDC gene products will play. Here we report our biochemical characterizations of the interactions of UmuD and UmuD' with the pol III beta processivity clamp. These analyses demonstrate that UmuD possesses a higher affinity for beta than does UmuD' because of the N-terminal arm of UmuD (residues 1-39), much of which is missing in UmuD'. Furthermore, we have identified specific amino acid residues of UmuD that crosslink to beta with p-azidoiodoacetanilide, defining the domain of UmuD important for the interaction. We have recently proposed a model for the solution structure of UmuD(2) in which the N-terminal arm of each protomer makes extensive contacts with the C-terminal globular domain of its intradimer partner, masking part of each surface. Taken together, our findings suggest that UmuD(2) has a higher affinity for the beta-clamp than does UmuD'(2) because of the structures of its N-terminal arms. Viewed in this way, posttranslational modification of UmuD, which entails the removal of its N-terminal 24 residues to yield UmuD', acts in part to attenuate the affinity of the umuD gene product for the beta-clamp. Implications of these structure-function analyses for the checkpoint and translesion DNA synthesis functions of the umuDC gene products are discussed.  (+info)

The effects of ranolazine on cardiac ion currents at concentrations within the therapeutic range (ie, 2 to 6 μmol/L) include inhibition of IKr, late INa, and late ICa,L. Inhibition of IKr by ranolazine prolongs APD, and its effect to inhibit late INa and late ICa,L abbreviates APD. The net effect and clinical consequence of inhibition of these ion channel currents is a modest increase in the mean QTc interval over the therapeutic range. The drug differs significantly from other agents that block IKr and induce TdP. Ranolazine-induced prolongation of the APD is rate independent (ie, does not display reverse rate-dependent prolongation of APD) and is not associated with EADs, triggered activity, an increase in spatial dispersion of repolarization, or polymorphic ventricular tachycardia. Indeed, rather than displaying arrhythmogenic activity, ranolazine, via its actions to suppress EADs and reduce TDR, possesses significant antiarrhythmic activity, acting to suppress the arrhythmogenic effects ...

Of the 6, acetanilide and aniline will have the highest melting points as they are polar. Between the two, I reasoned that acetanilide will have a higher melting point because it has a polar carbonyl group in addition to the h-bonding provided by the nitrogen bonded to a hydrogen. This stands in contrast to the mere nitrogen bonded to two hydrogens in the aniline. I have to admit, my reasoning here is fuzzy. As it stands, Im comparing carbonyl & N-H (acetanilide) to N-H & N-H (aniline). How do we know that dipole + hydrogen bonding is better than hydrogen bonding + hydrogen bonding?

Recently, there has been interest in the antiarrhythmic potential of the novel antianginal agent, ranolazine, the first Food and Drug Administration-approved drug that specifically blocks the late component of the Na+ current. Like most antiarrhythmics that target cardiac ion channels (eg, flecainide and amiodarone), ranolazine blocks multiple channels, including the repolarizing hERG current IKr, with therapeutic concentrations. The result is a mild concentration-dependent QTc prolongation seen in patients with chronic stable angina.11 Because of this, ranolazine is contraindicated for patients using other QT-prolonging drugs, those with preexisting QT prolongation,12 and those with repolarization abnormalities.. In this study, we sought to use a computationally based approach to determine whether ranolazines unintended pathological block of promiscuous K+ channels would prevail over therapeutic drug effects in 2 specific patient populations: LQT3-ΔKPQ carriers and those with acquired ...

The ability of butachlor to induce cytotoxicity, clastogenicity and DNA damage was assessed using Chinese hamster ovary cells (CHO), Swiss mouse embryo fibroblasts (MEF) and human peripheral blood lymphocytes. A dose and time dependent loss of viability was evident upon treatment of CHO cells with butachlor. Cell killing to an extent of 50 % was observed when cells were treated with 16.2 μg/ml of butachlor for 24 hr or with 11.5 μg/ml for 48 hr. The herbicide induced micronuclei significantly in cultured lymphocytes at 24 and 48 hr of treatment suggesting that it is clastogenic. To understand the mechanism of cell death caused by butachlor, its effect on DNA strand breaks was studied in MEF. A concomitant decrease in cell viability was observed with increase in DNA strand breaks. Agarose gel electrophoresis of DNA from herbicide treated CHO cells and cytochemical staining indicate the induction of apoptosis by butachlor ...
Background:. Patients with ischemic heart disease often report multiple symptoms, including angina and palpitations.. Ranolazine is a novel antianginal and antiischemic drug that reduces intracellular sodium and calcium accumulation during ischemia thus limiting ischemic injury. Furthermore, ranolazine has antiarrhythmic effects which are largely a result of the drugs effect on multiple ion channels.. It has previously been shown that treatment with ranolazine can reduce the frequency of supraventricular and ventricular tachycardia in the short term. In a subgroup analysis of the MERLIN-TIMI 36 trial, the continuous ECGs of 6,351 patients were analyzed. The results showed that, in comparison with placebo, treatment with ranolazine resulted in fewer episodes of ventricular tachycardia that lasted 8 beats or longer (5.3% versus 8.3%; P ,0.001), and in fewer episodes of supraventricular tachycardia (44.7% versus 55%; P ,0.001) and new-onset atrial fibrillation (1.7% versus 2.4%; P=0.08)..

The primary objective is to assess whether the increased angina threshold on ranolazine and subsequent higher training intensity will result in improved exercise tolerance and oxygen consumption; and greater than that observed with exercise training on placebo. The study team anticipates the chronic exercise improvements with ranolazine will be incrementally higher than the acute effects provided by ranolazine alone and demonstrated in previous trials. Key secondary objectives include the acute ranolazine and chronic exercise plus ranolazine effects on total daily energy expenditure (TDEE) and angina-related quality of life ...

Several series of ligands, designed to chelate silver(I) specifically in the presence of base metals, have been synthesised. The ligands include: - dithiodiamide compounds, prepared by the condensation of acetanilide derivatives with 1,2-dibromoethane; propanenitrile and propanoic ester derivatives prepared from pyridine-2-carbaldehyde via the Morita-Baylis-Hillman reaction; and novel malonamide ligands from the reaction of diethyl malonate with a range of primary amines. The malonamide derivatives were prepared under both conventional thermal and microwave-assisted conditions, the latter proving to be highly efficient. The ligands were all characterised using a combination of spectroscopic and, where appropriate, elemental analysis; in one case, the structural assignment was confirmed by single-crystal X-ray analysis. The fragmentation patterns in the electron-impact mass spectra of the malonamide derivatives have been explored using high-resolution and meta-stable peak scanning ...
Key value for chemical safety assessment Koc at 20 °C: , 18 Log Koc at 20 °C: , 1.26 The HPLC method at pH 2 and at pH 7 using soil-adsorption-reference data was applied for the determination of the adsorption coefficient (Koc) of the substance, in accordance with EC C.9 and OECD 121 and according to the principles of GLP. At pH 2, most of the substance will be in its non-ionised form. At pH 7, the test substance will be fully ionised. The HPLC chromatogram of the test substance showed one peak at 1.1 minutes at pH 2 and one peak at 0.5 minutes at pH 7. Under the same analytical conditions, the retention time of the reference substance Acetanilide (log Koc = 1.26) was higher at both pHs. Hence, it was concluded that the log Koc of the test substance at pH 2, as well as at pH 7, was , 1.26. ...
In the late 19th century, derivatives of aniline such as acetanilide and phenacetin emerged as analgesic drugs, with their cardiac-suppressive side effects often countered with caffeine.[26] During the first decade of the 20th century, while trying to modify synthetic dyes to treat African sleeping sickness, Paul Ehrlich - who had coined the term chemotherapy for his magic bullet approach to medicine - failed and switched to modifying Béchamps atoxyl, the first organic arsenical drug, and serendipitously obtained a treatment for syphilis - salvarsan - the first successful chemotherapy agent. Salvarsans targeted microorganism, not yet recognized as a bacterium, was still thought to be a parasite, and medical bacteriologists, believing that bacteria were not susceptible to the chemotherapeutic approach, overlooked Alexander Flemings report in 1928 on the effects of penicillin.[27]. In 1932, Bayer sought medical applications of its dyes. Gerhard Domagk identified as an antibacterial a red azo ...

Antitumor drugs may cause asymptomatic diastolic dysfunction that introduces a lifetime risk of heart failure or myocardial infarction. Cardio-oncology is the discipline committed to the cardiac surveillance and management of cancer patients and survivors; however, cardio-oncology teams do not always attempt to treat early diastolic dysfunction. Common cardiovascular drugs, such as β blockers or angiotensin converting enzyme inhibitors or others, would be of uncertain efficacy in diastolic dysfunction. This perspective describes the potential value of ranolazine, an antianginal drug that improves myocardial perfusion by relieving diastolic wall tension and dysfunction. Ranolazine acts by inhibiting the late inward sodium current, and pharmacological reasonings anticipate that antitumor anthracyclines and nonanthracycline chemotherapeutics might well induce anomalous activation of this current. These notions formed the rationale for a clinical study of the efficacy and safety of ranolazine in ...

Programmed electrical stimulation was performed in eight normal dogs using a stimulator and endocardiai electrode catheters identical to those used in human studies. The right and left ventricular apex were paced at a drive cycle length of 400 ms and, in some cases, 500 ms, with a pacing sequence of single (S1S2), double (S1S2S3) and triple (S1S2S3S4) premature impulses introduced after eight paced complexes. Pacing sequences were performed using combinations of pulse width (1, 2 and 4 ms) and current strengths of 2, 5 and 10 times diastolic threshold, and in three dogs, 15 times diastolic threshold.. Twenty-two episodes of ventricular fibrillation were initiated in five dogs in 170 pacing sequences using current strengths up to 10 times diastolic threshold, and six episodes of ventricular fibrillation in the two of three remaining dogs tested at 15 times diastolic threshold. Ventricular fibrillation was reproducible on seven of nine occasions. Ventrieular fibrillation was never induced by ...
The present study was undertaken to evaluate the influence of butachlor, a widely used herbicide, on antioxidant enzyme system and lipid peroxidation formation in African cat fish (Clarias gariepinus). Fish were exposed to sub-lethal concentrations of butachlor 1, 2, 2.5 ppm and sacrificed 24hrs after treatment. A significant increase in malondialdehyde formation was observed in the liver, kidney, gills and heart of the fish following exposure to different concentrations of butachlor. Superoxide dismutase and catalase activities increased in the liver and kidney but decreased in the gills and heart in a concentration-dependent pattern. Glutathione level and glutathione-Stransferase activities increased (P

In this trial of patients with T2DM, established CAD, and stable angina, ranolazine was more effective than placebo in reducing the primary outcome of average weekly angina episodes, as well as average weekly sublingual nitroglycerin use. These results were consistent across the subgroups of baseline average weekly angina episodes, number of concomitant antianginal medications, age, and sex. The therapeutic benefit of ranolazine versus placebo was greater among patients enrolled outside of Russia, Ukraine, and Belarus, and among those with higher baseline HbA1c. In addition, ranolazine was safe and well tolerated in this patient population.. While patients with T2DM and CAD have more extensive disease (7,8) and worse outcomes (20,21) than those without DM, the data on whether they experience more angina are conflicting. Several older studies suggested that patients with DM have less angina than their non-DM counterparts due to an increased likelihood of "silent" ischemia related to diabetic ...
Accordingly, the Metabolic Efficiency with Ranolazine for Less Ischemia in Non-ST Elevation Acute Coronary Syndromes (MERLIN TIMI-36) study, presented today at the American College of Cardiologys 56th Annual Scientific Session, had the dual objectives to provide new long-term safety data on ranolazine in a high-risk population of patients with acute coronary syndromes (ACS) and to study the drugs efficacy in a broad population of people with unstable angina due to ACS. ACC.07 is the premier cardiovascular medical meeting, bringing together cardiologists and cardiovascular specialists from around the world to further breakthroughs in cardiovascular medicine. The efficacy data showed that ranolazine did not produce a statistically significant reduction in the composite endpoint of cardiovascular death, heart attack and recurrent ischemia (the primary efficacy endpoint of the study), but did show a statistically significant reduction in recurrent ischemia alone. The data showed no adverse trend ...

Arrhythmias arise from breakdown of orderly action potential (AP) activation, propagation and recovery driven by interactive opening and closing of successive voltage-gated ion channels, in which one or more Na+ current components play critical parts. Early peak, Na+ currents (I Na) reflecting channel activation drive the AP upstroke central to cellular activation and its propagation. Sustained late Na+ currents (I Na-L) include contributions from a component with a delayed inactivation timecourse influencing AP duration (APD) and refractoriness, potentially causing pro-arrhythmic phenotypes. The magnitude of I Na-L can be analysed through overlaps or otherwise in the overall voltage dependences of the steady-state properties and kinetics of activation and inactivation of the Na+ conductance. This was useful in analysing repetitive firing associated with paramyotonia congenita in skeletal muscle. Similarly, genetic cardiac Na+ channel abnormalities increasing I Na-L are implicated in triggering
Background: Patients with coronary microvascular dysfunction (CMD) often have diastolic dysfunction, representing an important therapeutic target. Ranolazine-a late sodium current inhibitor-improves diastolic function in animal models and subjects with obstructive coronary artery disease (CAD). Hypothesis: We hypothesized that ranolazine would beneficially alter diastolic function in CMD. Methods: To test this hypothesis, we performed retrospective tissue tracking analysis to evaluate systolic/diastolic strain, using cardiac magnetic resonance imaging cine images acquired in a recently completed, randomized, double-blind, placebo-controlled, crossover trial of short-term ranolazine in subjects with CMD and from 43 healthy reference controls. Results: Diastolic strain rate was impaired in CMD vs controls (circumferential diastolic strain rate: 99.9% ± 2.5%/s vs 120.1% ± 4.0%/s, P = 0.0003; radial diastolic strain rate: −199.5% ± 5.5%/s vs −243.1% ± 9.6%/s, P = 0.0008, case vs control). ...

Program abstracts for 32nd annual North American meeting of the Society of Environmental Toxicology and Chemistry,November 13-17, 2011 Boston MA.. The use of herbicides to combat weeds is an important practice in modern agriculture. During the 1990s, crops which were genetically-modified (GM) to tolerate the effects of a specific herbicide, most commonly glyphosate, were introduced and widely accepted. In 2007, glyphosate-tolerant GM-soybeans, cotton and corn comprised 95, 80 and 59 percent of these crops, respectively. The widespread adoption of herbicide-tolerant GM crops has caused a major shift away from the use of conventional pre-emergent herbicides (triazines, acetanilides, etc.) towards glyphosate. During the 2007 growing season, the air and rain at agricultural sites in Iowa and Mississippi were monitored for 23 ...
An existing method of oxidation involving oxodiperoxo(hexamethylphosphoramide)molybdenum(VI) has been adapted for the direct conversion of phenacetin and related amides to their respective hydroxamic acids. The hydroxamic acids are initially isolated as their stable dioxomolybdenum(VI) salts, in which form they can conveniently be stored and from which they are readily liberated by ligand displacement. The hydroxamic acids are of interest as the suspected toxic metabolites of several related drugs. The Mo(VI) derivatives of two analgesics, phenacetin and acetanilide, have been characterized by single-crystal X-ray diffraction. The ligand environment about the Mo atom is a markedly distorted octahedron in each case, with the dioxo O atoms bonded cis to each other, while trans to these bonds the hydroxamate Mo-O bonds are elongated. There is no conjugation between the phenyl rings and the hydroxamic acid group. Crystal data: MoO2L2, space group P21/c, Z = 4, a = 12.350 (6) Å, b = 17.477 (3) Å, c = 10
Based on the structural similarity of viral fusion proteins within the family Paramyxoviridae, we tested recently described and newly synthesized acetanilide derivatives for their capacity to inhibit measles virus (MV)-, canine distemper virus (CDV)- and Nipah virus (NiV)-induced membrane fusion. We found that N-(3-cyanophenyl)-2-phenylacetamide (compound 1) has a high capacity to inhibit MV- and CDV-induced (IC50=3 μM), but not NiV-induced, membrane fusion. This compound is of outstanding interest because it can be easily synthesized and its cytotoxicity is low [50 % cytotoxic concentration (CC50)≥300 μM], leading to a CC50/IC50 ratio of approximately 100. In addition, primary human peripheral blood lymphocytes and primary dog brain cell cultures (DBC) also tolerate high concentrations of compound 1. Infection of human PBMC with recombinant wild-type MV is inhibited by an IC50 of approximately 20 μM. The cell-to-cell spread of recombinant wild-type CDV in persistently infected DBC can be nearly
Vanadyl nitrate, also called vanadium oxytrinitrate or vanadium oxynitrate is a compound of vanadium in the +5 oxidation state with nitrate groups and oxygen. The formula is VO(NO3)3. It is made from dinitrogen pentoxide and vanadium pentoxide. It is a nitrating agent, adding nitro groups to aromatic compounds such as benzene, phenol, chlorobenzene, anisole, acetanilide, benzoic acid, ethyl benzoate, and toluene. Vanadyl nitrate can be made by soaking vanadium pentoxide in liquid dinitrogen pentoxide for durations around two days at room temperature. The yield for this method is about 85%. V2O5 + 3N2O5 → 2VO(NO3)3. Purification can be done by vacuum distillation. Vanadyl nitrate can also be made from vanadyl trichloride VOCl3 and dinitrogen pentoxide. Vanadyl nitrate is a pale yellow liquid. It is viscous but can be poured. VO(NO3)3 molecules have a distorted pentagonal bipyramid shape. The whole molecule has a Cs mirror symmetry. The vanadium oxygen double bond is in the same plane as a ...
Such exposes helped to promote the first federal Food and Drug Act, signed into law by President Theodore Roosevelt on June 30, 1906. The act was amended in 1912, and an even stronger Food, Drug and Cosmetic Act passed in 1938. These laws required drug labeling to include a list of ingredients and prohibited manufacturers from making false and misleading claims.. From 1906 to 1918 manufacturers could label their products with a "guaranty" that their medicine complied with the new food and drug law. The 1906 law required manufacturers to label their products if any of the following ingredients were present: alcohol, morphine, opium, cocaine, heroin, eucaine, chloroform, cannabis indica, chloral hydrate, or acetanilide. A complete listing of all ingredients was not required until 1938.. Federal food and drug regulation continues to evolve. Amendments to the laws in 1951 established clear distinctions between prescription and over-the-counter drugs. More recently, new regulations have introduced ...

How, really, can one differentiate ventricular fibrillation from "sustained" torsades? It is a minor point, but an important one nonetheless. The safety data collected were all performed in relatively healthy population (ambulatory - able to walk on a treadmill). Ranexa is metabolized in the liver almost exclusively and several common drugs (diltiazem, some macrolide antibiotics) increase its drug levels since they compete for the same metabolic pathway in the liver. To my knowledge, no data regarding this drugs metabolism in congestive heart failure (CHF) patients exists. As you know, liver function is greatly diminished in heart failure patients. It would seem logical to this cardiologist that knowledge of this fact is critical to our understanding of the safety of Ranexa, particularly in such a high-risk population for the development of CHF. Unfortunately, even TIMI-36 will not test this population, but at least its results will be the first look at survival differences in one ...

I worked really hard last several years. It was so nervous time for me, I was tired always - even I just got out of the bed. I felt depression. My thoughts was constantly negative. And my psychologist advised me to try Prozac.

I want to say, that just one month later I became another person! I become again friendly, polite and happy! My family, friends and colleagues - everybody, noticed my recovery.

i agree, if you can afford the extre money, get it done. you never know what they might find. I actually lost a puppy of mine like that. I got it from the local humane society when i was 18. Now thats going back a few years. The required that you get them spayed/neutered. I wasnt for the idea back then, i figured i didnt want mine removed so why would my dog. But i took him in to have the "simple" procedure done. Four hours later i get a phone call from the humane society and they tell me they "lost" my dog. I said how the hell do you loose a dog? They said there were complications during the surgery and he didnt make it. I was completely devistated, and it still hurts to this day. Who knows how things would have gone if i didnt take him in to get neutered. He might still be around today. So i will NEVER take any of my dogs in to get unecessary surgery ever again. I am just vigilant about their relations between boys and girls. I havent had a pregnancy yet ...

And these notes were not official write ups about behavior--if they had been we would have had to talk to the principal and take action. No, these notes were all about how Turbo did not meet the teachers standard for behavior. They really did not get along. And as I was picking up something for Turbo at the end of the year, I ran into his first grade teacher--she asked what we had planned for the summer and I told her he would be home and we would be doing normal summer things--she said to me, "I wish you luck with him" meaning Turbo. I really didnt know how to respond to that. Although later I got all kinds of offended. I can deal with my son just fine, and I dont need your wishes for luck ...
Later I suggested we go check out the other pool. It is 13 ft deep and most areas are for lap swimming but they have 2 small sections for rec swimming. The areas are next to a high dive. Boogie saw the high dive and begged me to let her try it. Again...this is my timid child! So she stood in line with a bunch of teenage boys and waited for her turn. I could tell she was getting nervous as she got closer but she climbed right up. I stopped myself from yelling "jump way out!" (being forever traumatized by the Greg Louganis incident) and just watched her. She walked right to the end and jumped off like a pro ...

BACKGROUND: The long-term outcome of an interventional strategy in patients with non-ST-elevation acute coronary syndrome is unknown. We tested whether an interventional strategy (routine angiography followed by revascularisation) was better than a conservative strategy (ischaemia-driven or symptom-driven angiography) over 5 years follow-up. METHODS: In a multicentre randomised trial, 1810 patients (from 45 hospitals in England and Scotland, UK) with non-ST-elevation acute coronary syndrome were randomly assigned to receive an early intervention (n=895) or a conservative strategy (n=915) within 48 h of the index episode of cardiac pain. In each group, the aim was to provide the best medical treatment, and also to undertake coronary arteriography within 72 h in the interventional strategy with subsequent management guided by the angiographic findings. Analysis was by intention to treat and the primary outcome (composite of death or non-fatal myocardial infarction) had masked independent ...
