Desert Bugs (Hemiptera: Heteroptera: Thaumastellidae): New records and review of the distribution and habitat of this relict group.

The known distribution and habitat information of the three described species of the genus Thaumastella Horváth, 1896 (Hemiptera: Heteroptera: Pentatomomorpha: Pentatomoidea: Thaumastellidae) are reviewed. In addition a fourth, undescribed species is reported from South Africa (Western Cape). Thaumastella aradoides Horváth, 1896, is recorded for the first time from Egypt, Oman, Saudi Arabia, United Arab Emirates, and the states of Khartoum and Sennar in Sudan.

Past, present and future of the two-spotted stink bug (Perillus bioculatus) in Europe revealed by citizen science.

The introduction of the Nearctic predaceous stink bug species, (Perillus bioculatus) was attempted multiple times in various countries throughout Europe to mitigate the damage caused by the invasive and harmful pest species, the Colorado potato beetle (Leptinotarsa decemlineata). Though these attempts were thought to be unsuccessful for decades, more recent data elucidated that the species have established small self-sustaining populations in the Balkans Peninsula, Southern Russia, and Türkiye and recently began to expand. In the past years, the European range of the species reached Eastern Europe.

TRPM4 regulates hilar mossy cell loss in temporal lobe epilepsy.

Background: Mossy cells comprise a large fraction of excitatory neurons in the hippocampal dentate gyrus, and their loss is one of the major hallmarks of temporal lobe epilepsy (TLE). The vulnerability of mossy cells in TLE is well known in animal models as well as in patients; however, the mechanisms leading to cellular death is unclear.

Results: Transient receptor potential melastatin 4 (TRPM4) is a Ca-activated non-selective cation channel regulating diverse physiological functions of excitable cells.

Regional Variation of Gap Junctional Connections in the Mammalian Inner Retina.

The retinas of many species show regional specialisations that are evident in the differences in the processing of visual input from different parts of the visual field. Regional specialisation is thought to reflect an adaptation to the natural visual environment, optical constraints, and lifestyle of the species. Yet, little is known about regional differences in synaptic circuitry.

In the list of the type material of Germalus ashlocki new species (page 362) the depository of the holotype was omitted by error. As a consequence, the name of the species is unavailable (International Code of Zoological Nomenclature, Fourth edition, Art. 16.

Apennocoris pilosulus: rediscovery of a forgotten big-eyed bug taxon from New Caledonia (Heteroptera: Lygaeoidea: Geocoridae).

Apennocoris pilosulus Montandon, 1907 (Hemiptera: Heteroptera: Lygaeoidea: Geocoridae), a peculiar representative of Geocorinae endemic to New Caledonia unreported since its original description is redescribed and illustrated based on its lectotype (designated in the present paper) and an additional non-type specimen. The placement of this monotypic genus within the subfamily Geocorinae is discussed.

An overview of the big-eyed bug fauna of French Polynesia (Heteroptera: Lygaeoidea: Geocoridae).

The representatives of the subfamily Geocorinae (Heteroptera: Lygaeoidea) distributed in French Polynesia are reviewed. Germalus ashlocki sp. nov.

Contributions to the knowledge of Umbrageocoris (Heteroptera: Lygaeoidea: Geocoridae).

Additions and corrections to original description of Umbrageocoris Kóbor, 2019 are provided along with the description of a new species and its two subspecies: Umbrageocoris maai maai ssp.n. from Borneo and the Malay Peninsula and Umbrageocoris maai timorensis ssp.

Connexin-36 distribution and layer-specific topography in the cat retina.

Connexin-36 (Cx36) is the major constituent of mammalian retinal gap junctions positioned in key signal pathways. Here, we examined the laminar and large-scale topographical distribution of Cx36 punctate immunolabels in the retina of the cat, a classical model of the mammalian visual system. Calretinin-immunoreactive (CaR-IR) cell populations served to outline the nuclear and plexiform layers and to stain specific neuronal populations.

Temporal properties of colour opponent receptive fields in the cat lateral geniculate nucleus.

The primordial form of mammalian colour vision relies on opponent interactions between inputs from just two cone types, 'blue' (S-) and 'green' (ML-) cones. We recently described the spatial receptive field structure of colour opponent blue-ON cells from the lateral geniculate nucleus of cats. Functional inputs from the opponent cone types were spatially coextensive and equally weighted, supporting their high chromatic and low achromatic sensitivity.

Receptive field properties of color opponent neurons in the cat lateral geniculate nucleus.

Most nonprimate mammals possess dichromatic ("red-green color blind") color vision based on short-wavelength-sensitive (S) and medium/long-wavelength-sensitive (ML) cone photoreceptor classes. However, the neural pathways carrying signals underlying the primitive "blue-yellow" axis of color vision in nonprimate mammals are largely unexplored. Here, we have characterized a population of color opponent (blue-ON) cells in recordings from the dorsal lateral geniculate nucleus of anesthetized cats.

Comparative immunohistochemical study of tissue integration of macroporous and laminar surgical meshes.

Intraperitoneal surgical mesh implantation is required for laparoscopic ventral hernia repair. Composite meshes are well known in animal models and human practice. The aim of our study is to compare the biological behaviour of two different textured silicone-covered polypropylene meshes.
