Enhanced bioavailability of polyaromatic hydrocarbons in the form of mucin complexes.

Increasing exposure of biological systems to large amounts of polycyclic aromatic hydrocarbons is of great public concern. Organisms have an array of biological defense mechanisms, and it is believed that mucosal gel (which covers the respiratory system, the gastrointestinal tract, etc.) provides an effective chemical shield against a range of toxic materials.

[Prognostic, diagnostic, and therapeutic prospects of using adiponectine as a biomarker in cardiobascular diseases].

The role of adipose tissue as an important endocrine organ is today beyond doubt. The adipose tissue is known to be a source of many biologically active substances, adipocitokines, one of them being the adiponectine possessing anti-inflammatory, antiatherogenic and cardioprotective properties; it is believed to be one of prospective biomarkers for risk assessment, for diagnostics and, possibly, for therapy of cardiovascular diseases.

Xanthopterin in the Oriental hornet (Vespa orientalis): light absorbance is increased with maturation of yellow pigment granules.

The Oriental hornet bears both brown and yellow colors on its cuticle. The brown component is contributed by the pigment melanin, which is dispersed in the brown cuticle and provides protection against insolation, while the yellow-colored part contains within pockets in the cuticle granules possessing a yellow pigment. These yellow granules (YG) are formed about 2 days prior to eclosion of the imago, and their production continues for about 3 days posteclosion.

Ontogenesis of the thermogenic center in hornets.

In the Oriental hornet, a thermogenic center is located in its prothorax. The present study attempted to elucidate the development of this organ with age, that is, by following the development of the thermogenic center in the hornet from its pupal stage until several days after eclosion of the imago. To this end, use was made of an infrared camera, with which pictures were taken of the prothorax in hornets at various ages, i.

MRI of oriental hornet head.

The head of the Oriental hornet in situ, detached from a live sample was imaged using Magnetic Resonance Imaging (MRI). This non-invasive method enabled us to visualize the three-dimensional structure of the hornet's brain and intracerebral organs, as based on cubic voxels of 23 microm3. From these images, we could identify various cephalic structures in both supra-esophageal and sub-esophageal locations.

Diazepam inhibits reproduction and reproductive behavior of oriental hornet. A possible role for the peripheral-type benzodiazepine receptor.

Feeding of diazepam to young hornets completely inhibits or delays development of their ovaries for a relatively long period. In control hornets, the ovaries usually develop within a day or two post eclosion and comb building commences on the second day of life. The hornets then oviposit into the comb cells and the deposited ova give rise to larvae.

Prevention of hyperthermia with silk of the oriental hornet, Vespa orientalis: a hypothesis.

Wasps apparently develop normally even under extreme thermal conditions, including deserts. We deemed it worthwhile to set up an experiment wherein wasp brood combs containing a full gamut of brood ranging from eggs up to pupae and a few adults were kept in an incubator whose temperature was gradually raised to 45 degrees C, and the response of the disparate brood to such warming was photographed via Infra Red camera. The finding of this experiment showed that for open brood (i.

Thermovoltaic properties of hornet silk.

In silk from the larval silk caps of the Oriental hornet Vespa orientalis (Hymenoptera, Vespinae), temperature-dependent changes in the electric voltage have been recorded, with rise in the voltage occurring mainly upon rise in the temperature between 10-36 degrees C. The peak voltage was measured between 32-38 degrees C and attained 240-360 mV, but with further increase in temperature, the voltage decreased, dropping to 0 mV at about 45-50 degrees C. Upon second measurement (of same silk specimen), the voltage peak usually occurred later (by 8-9 degrees C) and at higher temperature than in the first measurement.

Presence of a thermoregulatory hot spot in the prothorax of the large carpenter bee and the bumble bee.

In both the large carpenter bee (Xylocopa pubescens) and the bumblebee (Bombus terrestris), a hot spot was detected in the center of the prothorax on its dorsal-external aspect. In both cases, the temperature in this hot spot was found to be greater than the ambient temperature and that at the tip of the gaster. In B.

[Transillumination phlebectomy in minimally-invasive surgical treatment of varicose disease].

Transillumination phlebectomy with TriVex was used in 72 patients for the surgical treatment of lower extremities varicose veins. Diagnostic protocol, indications and surgical technique are described in detail. Short- and long-term results are assessed.

The thermogenic center in social wasps.

In the social wasps Vespa orientalis and Paravespula germanica (Hymenoptera, Vespinae), a thermogenic center has been found in the dorsal part of the first thoracic segment. The temperature in this region of the prothorax is higher by 6-9 degrees C than that at the tip of the abdomen, and this in actively flying hornets outside the nest (workers, males or queens) as well as in hornets inside the nest that attend to the brood in the combs. On viewing the region from the outside, one discerns a canal or rather a fissure in the cuticle, which commences at the center of the dorsal surface of the prothorax and extends till the mesothorax.

Electrical properties of hornet silk: temperature dependence.

Hornet silk is a polymer of amino acids. One of the known properties of polymers is their electrical activity. The present study describes the results of electrical measurements carried out vertically on the silk cap of pupae of the Oriental hornet Vespa orientalis (Hymenoptera, Vespinae).

Antennal and cephalic organelles in the social wasp Paravespula germanica (Hymenoptera, Vespinae): form and possible function.

This paper deals with hairs and organelles present on the head and antennae of the German wasp, Paravespula germanica, and their possible role in sensing the physical and chemical ambience, as well as in intercommunicating both while in flight outside or in the nest. Via scanning electron microscope photography, we detected on the frons plate of the wasp's head, hairs that were about 300 microm long and comprised the longest hairs on the body of the wasps. Additionally, the two antennae bore along their entire length photoreceptors, placoids, campaniforms, trichoids, and agmons.

A thermoregulatory center in hornets: IR photography.

In the Oriental hornet Vespa orientalis (Hymenoptera, Vespinae), there is on the dorsal side of the thorax, beneath the mesoscutum plate of the prothorax and around the median notal suture, a lump that, in the course of hornet activity, is warmer by 9 degrees C from the surrounding milieu and by up to 6 degrees C from other body parts of the hornet. This lump is about 1 mm in diameter, butterfly-shaped, and its upper, posterior border abuts the base of the forewings. During hornet activity and via Infra Red photography one can observe heat extensions stemming from the center of the lump and proceeding forward in the direction of the head, downward toward the legs and backwards toward the bases of the wings.

Communication by electrical means in social insects.

Social insects, belonging to the order Hymenoptera, maintain a fixed, optimal temperature in their nest. Thus, in social wasps and hornets, the optimal nest temperature is 29 degrees C, despite the fact that they are distributed in regions of varying climates both in the northern and southern hemispheres of the globe. Since hornets and bees are relatively small insects, determination of their own body temperature as well as that of their nest and the brood was made via thermometers or by the use of infrared (IR) rays.

Temperature distribution and electrical properties along the Oriental hornet body.

The hornet is an endothermic insect. Daily variations in hornet surface temperature were measured. Three peaks were found between 9:30 and 10: 30 a.
