Free radical generation during the activation of hemolymph prepared from the homopteran Dactylopius coccus
Authors: García‐Gil De Muñoz F. , Lanz‐Mendoza H. , Hernández‐Hernández F.C. 
Published: April 2007

AbstractSuperoxide anion (O–2) and nitric oxide (NO) generation in Dactylopius coccus hemolymph obtained by perfusion and activated with zymosan was studied. Activated hemolymph reduced 3‐[4,5 dimethylthiazolil‐2]‐2,5‐diphenyl tetrazolium bromide. This reduction was prevented by superoxide dismutase (SOD) indicating O–2 generation. This activity was dependent on temperature, and hemolymph incubated at 75°C lost its activity. Chromatocytes incubated with zymosan released their content and produced O–2. Activated hemolymph also produced NO and this activity was prevented in the presence of NG‐nitro‐L‐arginine methyl ester, suggesting that nitric oxide synthase (NOS) might be present in D. coccus hemolymph. The probable source of O–2 in the D. coccus hemolymph is the anthraquinone oxidation, since commercial carminic dye produced O–2 during its oxidation by Agaricus bisporus tyrosinase. Gram+ Micrococcus luteus exposed to activated hemolymph were killed in vitro, and addition of NG‐nitro‐L‐arginine methyl ester and D‐Mannitol (a hydroxyl radical scavenger) prevented their killing. The cytotoxic effect produced by the activated hemolymph was not observed with the Gram– bacteria Serratia marcescens. These results suggest that D. coccus activated hemolymph generates reactive oxygen intermediates (ROI) and reactive nitrogen intermediates (RNI) that may limit M. luteus growth. Arch. Insect Biochem.

Regulation of pheromone biosynthesis in the “Z strain” of the European corn borer, Ostrinia nubilalis
Authors: Eltahlawy H.S. , Buckner J.S. , Foster S.P. 
Published: April 2007

AbstractThe regulation of pheromone biosynthesis by the neuropeptide PBAN in the Z strain of the European corn borer, Ostrinia nubilalis, was investigated using labeled intermediates. Injection of radiolabeled acetate showed PBAN did not influence the de novo synthesis of saturated fatty acids in the gland. When deuterium‐labeled myristic acid was topically applied to the gland, females injected with PBAN produced more labeled pheromone than did control females, indicating that PBAN controls one of the later steps of pheromone biosynthesis. Although more myristic acid was Δ11‐desaturated in the gland in the presence of PBAN, this was counterbalanced by less Δ11‐desaturation of palmitic acid, indicating that desaturase activity did not change overall. This change in flux of myristic acid through to pheromone was shown to be caused by increased reduction of fatty acid pheromone precursors occurring in the presence of PBAN. Arch. Insect Biochem.

New isoforms of odorant‐binding proteins and potential semiochemicals of locusts

Published: April 2007

AbstractTo obtain more information on the elements of chemical communication in the migratory locust (Locusta migratoria) (Orthoptera: Acrididae), we have searched for additional odorant‐binding proteins (OBPs) and for volatiles in the feces that could represent potential semiochemicals for this species. A two‐dimensional electrophoretic (2DE) analysis of an antennal extract showed only three closely positioned spots that were recognized by the antiserum against locust OBP. Three genes were also identified using PCR and 5′RACE‐PCR approaches, encoding isoforms differing from each other for a single amino acid substitution. The gas‐chromatographic‐electroantennogram (GC‐EAD) headspace analysis of a feces sample revealed the presence of several compounds that elicited dose‐dependent electrophysiological responses in the antennae of both sexes. Most of these compounds are different from those identified in the feces of the desert locust (Schistocerca gregaria) and reported to be behaviorally active. Ligand‐binding experiments performed with such volatiles and recombinant OBP did not show affinity, thus indicating that the binding pocket of OBP requires larger molecules than those so far identified.

Human skin permittivity determined by millimeter wave reflection measurements
Authors: Alekseev S.I. , Ziskin M.C. 
Published: April 2007

AbstractMillimeter wave reflection from the human skin was studied in the frequency range of 37–74 GHz in steps of 1 GHz. The forearm and palm data were used to model the skin with thin and thick stratum corneum (SC), respectively. To fit the reflection data, a homogeneous unilayer and three multilayer skin models were tested. Skin permittivity in the mm‐wave frequency range resulted from the permittivity of cutaneous free water which was described by the Debye equation. The permittivity increment found from fitting to the experimental data was used for determination of the complex permittivity and water content of skin layers. Our approach, first tested in pure water and gelatin gels with different water contents, gave good agreement with literature data. The homogeneous skin model fitted the forearm data well. Permittivity of the forearm skin obtained with this model was close to the skin permittivity reported by others. To fit reflection from the palmar skin with a thick SC, a skin model containing at least two layers was required. Multilayer models provided better fitting to both the forearm and palmar skin reflection data. The fitting parameters obtained with different models were consistent with each other.

A few remarks on ‘combined action of DC and AC magnetic fields on ion motion in a macromolecule’
Authors: Binhi V. N. 
Published: April 2007

AbstractZhadin and Barnes [2005:26:323–330] concluded that they solved the differential equation describing combined action of DC and AC magnetic fields on thermal motion of ions in a biological macromolecule and, as a result, a diversity of biological phenomena could be explained. It is shown here that biological phenomena cannot be explained based on this model. Adair [2006:27:332–334] gave several arguments for the statement that the interaction of weak magnetic fields with ions trapped in protein cavities cannot produce detectable biological effects through changing the character of the ion orbits. The arguments are analyzed here and some are shown to be questionable or unjustified. We stress the difference between the conclusion made by Adair and that stated in this article.

AbstractBeim Flussbarsch (Perca fluviatilis) ist der Kratzer (Pomphorhynchus laevis) als parasitischer Wurm bekannt. Der Flussbarsch ist der Endwirt, die Larve lebt im Bachflohkrebs (Rivulogammarus pulex) als Zwischenwirt und beeinflusst sein Verhalten: Statt vor seinem Fressfeind zu fliehen, schwimmt ein infizierter Bachflohkrebs dem Flussbarsch entgegen.

Identification of Protein Fold Topology Shared between Different Folds Inhibited by Natural Products
Authors: McArdle Bernadette M. , Quinn Ronald J. 
Published: April 2007

AbstractNatural products have withstood the test of time as therapeutics, but new lead‐generation strategies have focussed away from natural products. A new approach that uses natural‐product recognition to drive an understanding of biological space might provide an impetus for renewed focus on natural‐product starting points. Protein fold topology (PFT) has been shown to be an underlying factor for natural‐product recognition. An investigation of natural product inhibitors of the Zincin‐like fold has demonstrated their capacity also to inhibit targets of different fold types. Analysis of crystal structure complexes for natural products cocrystallised within different fold types has shown similarity at the PFT level. Two new PFTT (where subscript T denotes PFT shared between therapeutic targets) relationships have been established: the Zincin‐like– metallohydrolase/oxidoreductase PFTT and the Zincin‐like–phosphorylase/hydrolase PFTT. The PFT relationship between a natural product's biosynthetic enzyme and therapeutic target, and now between different fold targets of the same natural product, suggests that PFT is the simplest descriptor of biological space. This fundamental factor for recognition could facilitate a rational approach to drug development guided by natural products.
