Ein Beitrag zum Bindevermögen des Natriumpolyphosphates (NaPO3)x · H2O für Ca‐ und Mg‐Ionen, I. Mitteilung
Authors: Vogel H. 
Published: November 2006

AbstractDas Bindevermögen des Natriumpolyphosphates (NaPO3)x · H2O für Kationen, insbesondere für diejenigen des Kalziums oder Magnesiums, ist in Lösungen starker und schwacher Elektrolyten wechselnder Konzentration weitgehend abhängig vom „stöchiometrischen”︁ Aktivitätskoeffizienten des Fremd‐Elektrolyten und seinem Hydratationszustand. Für das „relative”︁ Bindevermögen wurde ein funktioneller Zusammenhang gefunden, der dem Grenzgesetz der Debye‐Hückel‐Beziehung zwischen Aktivitätskoeffizienten und ionaler Konzentration des gelösten Elektrolyten ähnlich ist. Das Bindevermögen kann von den Lösungspartnern sowohl verstärkend als auch abschwächend beeinflußt werden.

Authors: Cilia Roberto , Landi Andrea , Vergani Francesco , Sganzerla Erik , Pezzoli Gianni , Antonini Angelo 
Published: November 2006

AbstractExtradural motor cortex stimulation (EMCS) is a surgical procedure proposed for patients with advanced Parkinson's disease (PD) who cannot undergo deep brain stimulation (DBS). Five PD patients with motor fluctuations and dyskinesia underwent EMCS of the left hemisphere. All fulfilled CAPSIT criteria for DBS, with the exception of age > 70 years. Patients were assessed preoperatively and 6 months after surgery on and off medications, with stimulator on, and 2 weeks later with stimulator off. Outcome measures included changes in mean medication dosage (levodopa and dopamine agonists), Unified Parkinson's Disease Rating Scale (UPDRS Parts II–III and Item 39), and dyskinesias (Abnormal Involuntary Movements Scale [AIMS]). We found no significant mean changes following EMCS. However, there was a trend for a reduction of mean daily medication intake (−30%) and AIMS (−19%). There were 3 patients who reported reduced OFF time (UPDRS Item 39) and 4 of 5 who felt a subjective benefit in stability and gait. In our PD cohort, EMCS induced no objective benefit, although some subjective improvement was reported mostly on axial symptoms. © 2006 Movement Disorder Society

Synthesis and polymerization of a new nitrogen‐containing bis‐ortho‐diynylarene monomer
Authors: Zengin Huseyin , Zengin Gulay , Smith Dennis W. 
Published: November 2006

AbstractThis study focuses on the preparation, characterization, and optical properties of new bis(3,4‐diphenylethynylphenyl)phenylamine. This is the first nitrogen‐containing bis‐ortho‐diynylarene (BODA) monomer having a nitrogen atom as the spacer group. BODA monomers are usually prepared from common bisphenols, thereby providing great synthetic versatility and the opportunity to develop a wide array of novel polyarylene thermosets by varying the aromatic spacer group. The new bis(3,4‐bisphenylethynylphenyl)phenylamine was synthesized in five steps. This compound emits an intense blue color (λ = 438 nm) upon irradiation by UV light and may be suitable for use as an emitting layer in electroluminescent devices. Bis‐(3,4‐bisphenylethynylphenyl)phenylamine and its polymer have photoluminescence quantum yields 34 and 38%, respectively, and long excited‐state lifetimes of 3.2 and 3.6 ns, respectively. The structure of the monomer and its polymer were characterized using spectroscopic techniques including Ultraviolet–visible Spectrophotometer, Photoluminescence Spectrophotometer, Fourier Transform infrared spectroscopy, and Gel Permeation Chromatography. The polymerizations were studied by Differential Scanning Calorimeter. The amount of weight loss and the thermostability of the nitrogen‐containing polymer were determined from thermogravimetric analysis. The electrical conductivity of neat HCl‐doped BODA‐derived polymer film was measured according to the standard four‐point probe technique. © 2006 Wiley Periodicals, Inc.

Surveys of sheep dipping in Britain
Authors: Leech F. B. , Macrae W. D. 
Published: November 2006

AbstractSurveys of sheep dipping and spraying during 1965–66 showed that, after the end of 1965, the use of organochlorine formulations decreased greatly, and the use of organophosphorus formulations and formulations containing both organochlorine and organophosphorus compounds increased. The ways in which toxic residues were disposed of, and the hazards, are summarised.
Pesticide residues in fat of cattle treated with backrubbers impregnated with coumaphos, methoxychlor or DDT
Authors: Burnett Ellen M. 
Published: November 2006

AbstractCattle were treated thrice weekly for 12 weeks with simulated backrubbers impregnated with 1% solutions of pesticides in mineral oils.Both coumaphos and methoxychlor applied in S.A.E. 50 oil induced maximum residues of 0–21 ppm in omental fat after 12 weeks treatment. Application of DDT in S.A.E. 50 oil or in used crankcase oil induced residues of 0·5–7 ppm DDT in omental fat after 12 weeks treatment. Where diesel fuel oil was the vehicle, DDT residues in omental fat were in the range 17–26ppm.
Polarography of demeton, disulfoton and phorate
Authors: Graham‐Bryce I. J. 
Published: November 2006

AbstractThe polarographic response obtained when demeton‐S, disulfoton and phorate, in 2% tetraethyl ammonium hydroxide, were investigated using a cathode ray oscilloscope polarograph depended considerably on the interval between making up solutions and measurement. Direct evidence to confirm previous suggestions that this type of behaviour is due to hydrolysis of the original insecticides to polarographically active SH‐containing compounds was obtained by measuring the disappearance of the original insecticides from the solutions by gas‐liquid chromatography and by investigating the behaviour of the hydrolysis product for demeton‐S and disulfoton synthesised by an independent route. Measurements of electrocapillary curves and other lines of evidence indicate that the electrode process involves adsorption/desorption at the mercury drop. The results emphasise that conditions must be carefully standardised if polarography is used for estimating these insecticides.

Effect of MCPA and MCPB on 32P accumulation and its incorporation into ATP in Vicia faba L.
Authors: Matlib M. A. , Kirkwood R. C. 
Published: November 2006

AbstractTreatment of excised bean root tissue with MCPA and MCPB resulted in a reduced uptake and incorporation of 32P into ATP accompanied by enhanced or reduced respiration. In all cases MCPB was found to be more toxic than MCPA. These results are explained on the basis that ATP is the energy source for phosphate uptake and that a reduction in ATP synthesis with MCPA and MCPB results in lowered phosphate uptake.
Effectiveness of the (+)‐trans‐chrysanthemic acid ester of (±)‐allethrolone (bioallethrin) against four insect species
Authors: Davies Mary S. , Chadwick P. R. , Holborn J. M. , Stewart D. C. , Wickham J. C. 
Published: November 2006

AbstractThe activity of the (+)‐trans‐chrysanthemic acid ester of (±)‐allethrolone (Bio‐allethrin) is shown to be superior to that of the (±)‐cis, trans‐isomers (allethrin), against houseflies, two species of grain beetle and larvae of the yellow fever mosquito. The efficiency of the (+)‐trans‐isomer compares favourably with that of pyrethrins when each is used alone or with piperonyl butoxide.
Residues of tetrachlorvinphos and its breakdown products on treated crops. III.—Residues on a range of field crops
Authors: Beynon K. I. , Edwards M. J. 
Published: November 2006

AbstractA wide range of crops including top fruit, cereals, brassicas, root vegetables and cotton from field trials in several countries in 1965, 1966, 1967 and 1968 have been analysed for residues of tetrachlorvinphos (Gardona, trans‐homer of dimethyl 1‐(2′,4′,5′‐trichlorophenyl)‐2‐chlorovinyl phosphate) foliar insecticide, its isomer and its potential breakdown products.The residues under field conditions were mainly of tetrachlorvinphos, its isomer and 1‐(2′,4′,5′‐trichlorophenyl)ethan‐1‐ol in free and sugar‐conjugated forms. Tetrachlorvinphos was not unduly persistent on the crops and its initial half‐life varied from 2 days on cabbage, to 7 days on potato foliage and to 12 days on pears (after the last of five applications). From one week after the final application onwards the highest residues of tetrachlorvinphos observed were on olives (1 ppm after 18 days after a single application of 0·1 % active material), maize leaf (2·8 ppm at 9·5 weeks after the last of two applications at 3 kg/ha), and cabbage (1·9 ppm at 12 days after the last of three applications at 0·5 kg/ha). The maximum residues of the alcohol in the free form were 3·2 ppm on maize leaf at 8 weeks from the second application at 1·5 kg/ha and in the conjugated form were 1·0 ppm on cauliflowers at 6 days after the last of four applications at 0·5 kg/ha.
Determination of aminozide residues in chrysanthemum tissues
Authors: Dicks J. W. 
Published: November 2006

AbstractA method initially developed for aminozide [succinic acid mono (2,2 dimethylhydrazide)] determination in apple fruit, involving hydrolysis to unsymmetrical dimethylhydrazine and oxidation of the latter to form aldehyde, has been adapted for use with chrysanthemum tissues. Modifications include preparation of the standard curve from aminozide samples taken through the entire procedure, use of a smaller sample size routine concentration of distillates containing unsymmetrical dimethylhydrazine on a rotary evaporator to remove interfering volatile material and correction for low levels of ‘apparent aminozide’ found in untreated tissue.
Determination of trichlorfon and fenthion residues in animals of different species
Authors: Möllhoff E. 
Published: November 2006

AbstractOriginal results of analyses of residues of trichlorfon and fenthion and its metabolites following application of commercial products to cattle, sheep and pigs, together with results taken from the literature are compared. Despite the use of higher dose rates of trichlorfon, residues are lower than those of fenthion after dermal application. On the other hand, the residues of trichlorfon that occur in the animals following oral application briefly approach the theoretical maximum level in the tissues. The results are discussed in relation to the physical and chemical properties of the pesticides and their metabolites.
Control of wireworms with organophosphorus and carbamate insecticides
Authors: Edwards C. A. , Thompson A. R. 
Published: November 2006

AbstractCarbaryl, chlorfenvinphos, diazinon, disulfoton, parathion, phorate, fenitrothion, thionazin and trichlorphon were tested for their effectiveness in killing wireworms by broadcast treatments. Each insecticide was tested once or more in two field trials cropped with wheat and two cropped with potatoes. Phorate and parathion were very lethal to wireworms at 4 Ib active ingredient per acre (4–48 kg/ha). Thionazin and diazinon were intermediate in effectiveness and the other insecticides ineffective.
Some studies on the systemic activity of the thiophanate fungicides in plants
Authors: Mercer R. T. 
Published: November 2006

AbstractThree closely related fungicides, thiophanate (NF 35), thiophanate methyl (NF 44) and NF 48 have been found to be active against a wide range of diseases including the powdery mildews of apple, cucumber and barley; apple and pear scab and grey mould of soft fruit. This paper deals with the preliminary experiments to compare their relative mobilities and biological persistence in crop plants, using the powdery mildews as indicator infections.NF 44 and NF 48 in particular showed a high degree of systemic activity by root uptake and persistence of action against barley and cucumber mildew but very little systemic activity against apple mildew on potted rootstocks. They have also displayed trans‐laminar and localised movement towards the leaf apex in sprayed cucumber and barley leaves but movement was not so marked in sprayed apple leaves.NF 48 was also active as a seed dressing against loose smut of barley.
Selective herbicidal activity of iodide in relation to iodide accumulation and foliar peroxidase activity
Authors: Mynett A. , Wain R. L. 
Published: November 2006

AbstractThe response of several plant species (dwarf bean, tomato, pea, cabbage, nettle and buttercup) to treatment with iodide has been investigated. Selective toxicity of iodide has been confirmed, sensitive species exhibiting severe desiccation of the leaves.Iodination of cellular components following treatment of bean leaves with iodide has been demonstrated, indicating that the iodide undergoes intracellular oxidation to iodine. This is thought to be brought about by peroxidase enzymes. Peroxidase activities (in relation to iodide oxidation) in the leaves of the plants studied have been determined. Although very low peroxidase activities are correlated with iodide tolerance, the results obtained indicate that the extent to which iodide accumulates in the leaves is also an important contributory factor in iodide selective toxicity.

Persistence of some organophosphorus insecticides in hen‐house litter
Authors: Galley D. J. 
Published: November 2006

AbstractThin‐layer chromatography was used to assess semi‐quantitively the persistence of six organophosphorus insecticides in hen‐house litter. Malathion disappeared within 4 h of application. Carbofenthion was the most persistent. Four weeks after treatment the proportions of the applied doses extracted from the litter were: carbofenthion 46%, phorate 21%, diazinon 13%, coumaphos 7% and fenitrothion 3%.
Mode of entry of oxime carbamates into insects
Authors: Gerolt Ph. 
Published: November 2006

AbstractThe outcome of our earlier work suggested that the transport of contact insecticides into insects does not involve the haemolymph, but that the chemical probably reaches the internal organs by migrating in and/or over integumental tissue. This applies to various insects having quite different integumental organisation, and to various groups of insecticides differing widely in physical and chemical characteristics.The present work has shown that carbamates (1‐alkylthioacetaldoxime carbamates) with high water solubility are no exception. The permeability of the body wall of the housefly for the methyl homologue (methomyl) which is the most water‐soluble of the series, although relatively high, is not high enough to account for the toxicity of the compound if it followed the haemolymph route. Methomyl when injected with water instead of an organic solvent was also found to be less toxic than the equivalent amount topically applied.Lateral migration in the integument could be demonstrated with all the carbamates tested and dissimilarities in rates were apparent. Methomyl migrated the most rapidly and the cyanomethylene homologue the most slowly. Differences in mobility may be partly responsible for inequality in toxic effect, but it is thought that metabolic detoxication is of over‐riding importance.
