A synopsis of the numbers of testicular follicles and ovarioles in true bugs (Heteroptera, Hemiptera) - sixty-five years of progress after J. Pendergrast's review.

The structure of testes and ovaries can be described in its simplest form by the number of follicles and ovarioles they contain. Sixty-five years after the last review of the internal reproductive systems in true bugs (Heteroptera), the data accumulated today on the number of testicular follicles and ovarioles in their gonads are summarized. In addition, data on the number and type (mesadenia/ectadenia) of accessory glands are given.

(Gesneriaceae), a new species from limestone areas of northern Vietnam.

, a new species of Gesneriaceae from Ha Giang Province, northern Vietnam, is here described and illustrated. It has many branched stems, diamond-shaped involucre with two cirrose opposite apices, a pink corolla, red spotted inside, and a flowering time in January-February. Among congeners with an externally hairy corolla, this new species is morphologically close to and .

Chromosomal and DNA barcode analysis of the Staudinger, 1881 species complex (Lepidoptera, Nymphalidae).

The species of the Staudinger, 1881 complex are distributed in Central Asia. Here we show that this complex is a monophyletic group including the species, , Sheljuzhko, 1929 and Fruhstorfer, 1917. The haploid chromosome number n=29 is found in and and is, most likely, a symplesiomorphy of the complex.

Comparative analysis of wild and cultivated Lathyrus L. species to assess their content of sugars, polyols, free fatty acids, and phytosterols.

Under the condition of climate change, the need for crops resistant to abiotic and biotic stresses is increasing. Lathyrus spp. are characterized by a high nutritional value of their green biomass.

The role of polymorphic variants of arginase genes (ARG1, ARG2) involved in beta-2-agonist metabolism in the development and course of asthma.

Asthma is a common severe disease of the respiratory tract, it leads to a significant impairment in the quality of a patient's life unless effectively treated. Uncontrolled asthma symptoms are a cause of disease progression and development, they lead to an increase in the patient's disability. The sensitivity to asthma therapy largely depends on the interaction of genetic and epigenetic factors, which account for about 50-60 % of variability of therapeutic response.

Five new genera of the subfamily Cylapinae (Insecta, Heteroptera, Miridae) from Australia.

Cylapinae is one of the poorly studied groups within the megadiverse family Miridae (Insecta: Heteroptera). In this paper, five monotypic genera from Australia are described as new to science. Two of those taxa, and , and and are assigned to the tribe Cylapini.

Karyotype reinvestigation does not confirm the presence of two cryptic species and interspecific hybridization in the () complex in the Crimea (Lepidoptera, Lycaenidae).

The karyotype of the blue butterflies from the Angarskiy Pass (Crimea), previously attributed to Polyommatus (Agrodiaetus) poseidon (Herrich-Schäffer, 1851), was re-examined. In all 19 studied individuals, we found the haploid chromosome number n = 26, including 7 pairs of relatively large and 19 pairs of relatively small chromosomes. According to the chromosome number and karyotype structure, the studied population does not differ from P.

Thermal decomposition of GaAs nanowires.

The realization of GaAs nanowire (NW) high-performance quantum devices operated at room temperatures requires that their diameters have to be less than 10 nm. It is shown, that the GaAs NWs with sub 10 nanometers diameters can be fabricated using the thermal decomposition technique. It is demonstrated, that depending on annealing conditions, the NW lengths, as well as shapes, can be modified significantly.

Rove beetles of the genus (Coleoptera, Staphylinidae) of Russia: a key to species and annotated catalogue.

This paper is the first inventory of the fauna of the rove beetle genus in the Russian Federation. It provides an annotated catalogue of 88 species of currently recorded from Russia, based on several collections and a critical evaluation of all earlier published records. All species are listed with a summary of their overall distribution and bionomics.

Two types of highly ordered micro- and macrochromosome arrangement in metaphase plates of butterflies (Lepidoptera).

In karyotype of many organisms, chromosomes form two distinct size groups: macrochromosomes and microchromosomes. During cell divisions, the position of the macro- and microchromosomes is often ordered within metaphase plate. In many reptiles, amphibians, birds, insects of the orthopteran family Tettigoniidae and in some plants, a so called "reptilian" type organization is found, with microchromosomes situated in the center of metaphase plate and with macrochromosomes situated at the periphery.

Review of the subgenus Plumiger of , with description of a new species (Heteroptera, Miridae, Halticini).

The Caucasian subgenus Plumiger Horváth, 1927 of the halticine genus Fieber, 1870 is revised. A key, updated diagnoses, and data on distribution are given for the subgenus and its four species, including (Georgia and Dagestan), and the previously unknown male of Drapolyuk, 1989. Illustrations of the male and female genitalia, photographs of the dorsal habitus, and SEM micrographs of selected structures are provided for all species of the subgenus.

23 International Colloquium on Animal Cytogenetics and Genomics (23 ICACG) June 9-12, 2018, Saint-Petersburg, Russia.

In memory of Ingemar Gustavsson 23 International Colloquium on Animal Cytogenetics and Genomics (23 ICACG) took place in June 9-12, 2018 in Saint-Petersburg, Russia. Organized biennially, the Colloquium runs from 1970. From its very start this meeting is associated with the name of Ingemar Gustavsson to whom we dedicated the Colloquium 2018.

Electronic structure of (In,Mn)As quantum dots buried in GaAs investigated by soft-x-ray ARPES.

Electronic structure of a molecular beam epitaxy-grown system of (In,Mn)As quantum dots (QDs) buried in GaAs is explored with soft-x-ray angle-resolved photoelectron spectroscopy (ARPES) using photon energies around 1 keV. This technique, ideally suited for buried systems, extends the momentum-resolving capabilities of conventional ARPES with enhanced probing depth as well as elemental and chemical state specificity achieved with resonant photoexcitation. The experimental results resolve the dispersive energy bands of the GaAs substrate buried in ∼2 nm below the surface, and the impurity states (ISs) derived from the substitutional Mn atoms in the (In,Mn)As QDs and oxidized Mn atoms distributed near the surface.

Geology and environments of subglacial Lake Vostok.

The reconstruction of the geological (tectonic) structure and environments of subglacial Lake Vostok is based on geophysical surveys and the study of mineral particles found in cores of accreted ice and frozen lake water (sampled after the lake was unsealed). Seismic reflection and refraction investigations conducted in the southern part of Lake Vostok show very thin (200-300 m) sedimentary cover overlying a crystalline basement. Most of this thin veneer is thought to have been deposited during temperate-glacial conditions in Oligocene to Middle Miocene time (ca 34-14 Ma).
