Pholeuon comani
No full textRedescription of Pholeuon comani (see also Table 1) As the original description of Pholeuon comani (Ieniştea 1955) lacks several details, important in the tribe Leptodirini, such as the inner sac of the aedeagus, we propose here the redescription of this species. Very small species, with body and all its parts smaller than in Protopholeuon and in other species of Pholeuon. Total body length 3.18 mm (ɗ) and 3.47 mm (Ψ). Body shape elliptical, slightly more narrow anteriorly (Fig. 2), color light brownish, eyes absent. Antennae short (2.2 mm Ψ, 2.3 mm ɗ), slightly longer in males than in females: article 7 = 0.24 mm Ψ, 0.25 mm ɗ; article 8 = 0.15 mm Ψ and ɗ; article 9 = 0.21 mm Ψ, 0.22 mm ɗ; article 10 = 0.18 mm Ψ, 0.19 mm ɗ; article 11 = 0.22 mm Ψ, 0.24 mm ɗ. Length of articles 8, 9 and 11 twice their width, length of the articles 7 and the 10 is one and a half their width. Mouthparts very similar to examined species of Pholeuon (Figs. 4, a–d) (described for Pholeuon proserpinae Knirsch, 1913 by Moldovan et al. 2004): maxillary palpomeres thin and elongate; galea flattened and covered with dense pubescence like hair-brush; lacinea shorter than galea, and covered with strong and curved bristles; mandibles wide, with curved apex having two teeth and no denticle between them; masticator border has ramified hairs. Pronotum small, short (0.81 mm ɗ, 0.87 mm Ψ) and narrow (0.86 mm ɗ, 0.94 mm Ψ), but large relative to elytra; very narrow anteriorly (0.48 mm ɗ, 0.51 mm Ψ); posteriorly with almost parallel edges. Pronotum in lateral view as in Fig. 5. Elytra convex, length 2.17 mm ɗ and 2.40 mm Ψ, width 1.35 mm ɗ and 1.50 mm Ψ; anterior half slightly wider than posterior half; punctation scattered, not arranged in parallel lines. Elytral pubescence short and dense. Male tarsi 5 -segmented and female tarsi 4 -segmented. Protarsi length 0.31 mm (ɗ) and 0.24 mm (Ψ), width 0.10 mm (ɗ) and 0.06 mm (Ψ). In both sexes legs elongated, with long sensory setae and long claws; adhesive pads on tarsal setae present only in male (Figs. 4, e–f), as in all other species of Pholeuon. Aedeagus small (length 1.1 mm), dorsally with invagination less deep than in other species of Pholeuon; long apical and basal blades and very short body (median blade) (Fig. 6); median part of the invagination is completely reduced. Parameres apically thinner, slightly inflected, with three setae, as in all species of Pholeuon; inner sac with two tufts of sclerotized prickles (Fig. 6). Spermatheca (Fig. 7) similar to that of other species of Pholeuon. Mesopholeuon Moldovan, Racovi ţă & Dunay, new subgenus Type species: Pholeuon comani Ieniştea, 1955. Derivatio nominis: morphologically, the name Mesopholeuon refers to our view that this subgenus can be considered intermediate between Protopholeuon and Pholeuon. FIGURE 4.

Abbreviations: c—claw, e—empodium, g—galea, h—sensory setae, l—lacinea, lp—labial palp, mp—maxillar palp, t—teeth, u—unguitractor. Description and diagnosis. The adults have the attributes characteristic for all Pholeuon species and, additionally, the following combination of features: Body (Figs. 2, 3) very small (3.0– 3.5 mm in length), with typical pholeuonid form, elongated and slender; brown-reddish color. Head small with relatively short antennae. Pronotum relatively large, slightly wider than longer; extremely narrow anteriorly, almost half of the maximum width of the pronotum; posteriorly with parallel edges. Elytra elliptical, dorso-ventrally very convex with fine, short and dense punctation. Aedeagus (Fig. 6) small and robust, with less deep dorsal invagination, long apical and basal blades and very short body; median part of the invagination is completely reduced; parameres apically thinner, slightly inflected, with three setae; inner sac with two tufts of sclerotized prickles. The subgenus Mesopholeuon includes the smallest species of the genus. Body, pronotum, elytrae are the shortest and narrowest among the Pholeuon species. Some of the most distinct features of Mesopholeuon are the very reduced anterior part of pronotum (aPw on Fig. 3), and the short antennae. Other diagnostic characters of Mesopholeuon are in the aedeagus, particularly its small size due to the reduction of the median lobe, and dorsal invagination (Fig. 8) being less deep and completely reduced in its median part. The basal and apical blades are long, almost as long as in the other species of Pholeuon.Published as part of Moldovan, Oana Teodora, Racoviţă, Gheorghe & Dunay, Gejza, 2007, Reconsidering Pholeuon C.

Ly6Chi Monocytes Provide a Link between Antibiotic-Induced Changes in Gut Microbiota and Adult Hippocampal Neurogenesis
No full textSummaryAntibiotics, though remarkably useful, can also cause certain adverse effects. We detected that treatment of adult mice with antibiotics decreases hippocampal neurogenesis and memory retention. Reconstitution with normal gut flora (SPF) did not completely reverse the deficits in neurogenesis unless the mice also had access to a running wheel or received probiotics. In parallel to an increase in neurogenesis and memory retention, both SPF-reconstituted mice that ran and mice supplemented with probiotics exhibited higher numbers of Ly6Chi monocytes in the brain than antibiotic-treated mice. Elimination of Ly6Chi monocytes by antibody depletion or the use of knockout mice resulted in decreased neurogenesis, whereas adoptive transfer of Ly6Chi monocytes rescued neurogenesis after antibiotic treatment. We propose that the rescue of neurogenesis and behavior deficits in antibiotic-treated mice by exercise and probiotics is partially mediated by Ly6Chi monocytes

Subregional co-operation in East-Central Europe: the Visegrad Group and the Central European Free Trade Agreement
No full text'Der Beitrag analysiert die Entwicklung, den gegenwärtigen Stand und die Zukunft der Visegrad-Gruppe, eines der erfolgreichsten Foren für subregionale Kooperation in Ostmitteleuropa. Das Fehlen formalisierter institutioneller Strukturen hat ein flexibles, für Änderungen offenes Arrangement hervorgebracht. Gleichzeitig war es damit anfällig für Störungen, die mit einer stärker institutionalisierten Struktur vermieden werden hätten können. Während das vorrangige Ziel in den 1990er Jahren darin bestanden hatte, das Erbe der Vergangenheit zu beseitigen, einen Beitrag zur Auflösung des Warschauer Paktes und zum Rückzug der sowjetischen Truppen aus der Region zu leisten sowie die 'Rückkehr' der Länder nach Europa zu koordinieren, stehen heute die Integration in die EU, Hilfe bei der demokratischen Konsolidierung der Post-Meciar-Slowakei und pragmatische Zusammenarbeit in verschiedenen Bereichen im Vordergrund. Offen bleibt, ob die Gruppe nach einem EU-Beitritt noch Zukunft hat. Der Autor ist der Ansicht, dass sich das Zentraleuropäische Freihandelsabkommen nach der EU-Erweiterung erübrigen wird, während die Visegrad-Gruppe auch danach noch Restaufgaben zu erfüllen haben wird.' (Autorenreferat)'The paper analysis the evolution, current state and prospects of the Visegrad group, one of the more successful sub-regional co-operation frameworks of East-central Europe. The absence of formalized institutional structures made the arrangement flexible and thus adaptable to changes. At the same time it has been prone to spoilers that could have been avoided in case more established institutional structure had been established. Whereas in the early 1990s its prime objective was to eliminate the remnants of the past, contribute to the termination of the Warsaw Treaty and the withdrawal of the Soviet troops from the region and co-ordinate the countries' 'return to Europe', nowadays it strives to foster EU integration, help the post-Meciar democratic consolidation and development of Slovakia and carry out pragmatic co-operation in different areas. It is open to question whether the group could have a new life after the participating countries' upcoming EU accession. The author is of the view that whereas the Central European Free Trade Agreement will have to wind up when EU enlargement occurs, there is hope to continue the Visegrad group with a residual political agenda beyond it.'
