The Rivalry Strategies of Political Parties in Elections to the Assembly of Citizens of the Free and Hanseatic City of Hamburg

2013

The author undertakes to discuss the problem of rivalry strategies of political parties in elections to the Citizens’ Assembly of the Free and Hanseatic City of Hamburg. The broadness and multidimensional character of the subject area requires moving beyond the limits of political science and entering other related domains, like broadly-conceived historical sciences, also reaching for a number of establishments within legal-historical domains. Firmly grounded historical, legal, polity-related and political aspects of the unification of Germany in the context of German federalism, encouraged and obligated the author, to attempt to bring the above problem up to date. I think that thanks to a …

mGluR control of interneuron output regulates feedforward tonic GABAA inhibition in the visual thalamus

2011

Metabotropic glutamate receptors (mGluRs) play a crucial role in regulation of phasic inhibition within the visual thalamus. Here we demonstrate that mGluR-dependent modulation of interneuron GABA release results in dynamic changes in extrasynaptic GABAA receptor (eGABAAR)-dependent tonic inhibition in thalamocortical (TC) neurons of the rat dorsal lateral geniculate nucleus (dLGN). Application of the group I selective mGluR agonist dihydroxyphenylglycine produces a concentration-dependent enhancement of both IPSC frequency and tonic GABAA current (IGABAtonic) that is due to activation of both mGluR1a and mGluR5 subtypes. In contrast, group II/III mGluR activation decreases both IPSC freque…

Modifications in Evoked Activity in the Visual Cortex Induced by the Caudate Nucleus

1971

The visual system, like the other sensorial systems, is subjected to intrinsic, complex control, originating both in the retina (CHANG et al., 1959; ARDUINI and HIRAO, 1960; STERIADE, 1967) and in the visual cortex (BUSER et a/., 1963; JASSIK-GERSCHENFELD and ASCHER, 1963; MEULDERS, 1965), which regulates its input at various levels of the specific pathways. However, the visual system is also influenced by subcortical structures which, though not exerting on it a strictly selective control, determine notable modifications in the level of excitability of the cortical sensorial neurons. It is in fact we11 known that activation of the mesencephalic reticular formation, by increasing the level …

Data from: Not only for egg yolk - functional and evolutionary insights from expression, selection and structural analyses of Formica ant vitellogeni…

2015

Vitellogenin, a storage protein, has been extensively studied for its egg-yolk precursor role, and it has been suggested to be fundamentally involved in caste differences in social insects. More than one vitellogenin copy has been reported in several oviparous species, including ants. However, the number and function of different vitellogenins, their phylogenetic relatedness and their role in reproductive queens and non-reproductive workers has been studied in few species only. We studied caste biased expression of vitellogenins in seven Formica ant species. Only one copy of conventional vitellogenin was identified in Formica species, and three vitellogenin homologues, derived from ancient …

Anti-inflammatory effects of cinnamon extract and identification of active compounds influencing the TLR2 and TLR4 signaling pathways

2018

Purpose: Inflammatory processes are involved in many diseases. The bark of Cinnamomum verum and its extracts are well known for anti-inflammatory effects, but the underlying active compounds and chemical mechanisms are not yet fully identified. The objective of this study was to elucidate how cinnamon extract, specifically active compounds, and their combinations influence the signaling pathways of inflammation, especially through toll-like receptors TLR2 and TLR4. Methods: Bioassay-guided fractionation was performed for standard ethanolic cinnamon extract using high performance liquid chromatography followed by compound identification in the determined active fractions by high-resolution m…

Anterograde tracing of retinal afferents to the tree shrew hypothalamus and raphe

2000

The anterograde neuronal transport of Cholera toxin B subunit (CTB) was used in this study to label the termination of retinal afferents in the hypothalamus of the tree shrew Tupaia belangeri. Upon pressure-injection of the substance into the vitreous body of one eye, a major projection of the retinohypothalamic tract (RHT) was found to the hypothalamic suprachiasmatic nuclei (SCN). Although the innervation pattern was bilateral, the ipsilateral SCN received a somewhat stronger projection. Labeling was also found in the supraoptic nucleus and its perinuclear zone, respectively, mainly ipsilaterally as well as in the bilateral para- and periventricular hypothalamic regions without lateral pr…

Proportion of odorants impacts the configural versus elemental perception of a binary blending mixture in newborn rabbits.

2011

WOS: 000295167200002; International audience; Processing of odor mixtures by neonates is weakly understood. Previous studies showed that a binary mixture of ethyl isobutyrate/ethyl maltol (odorants A/B) blends in newborn rabbits at the 30/70 ratio: Pups would perceive a configural odor in addition to the components' odors. Here, we investigated whether the emergence of this additional odor in AB is determined by specific ratio(s) of A and B. To that goal, we tested whether pups discriminated between AB mixtures with lower (A(-)B, 8/92 ratio) or higher (A(+)B, 68/32) proportion of A. In Experiment 1, pups conditioned to A (or B) responded to A(-)B and A(+)B but not to AB. In Experiment 2, pu…

Neonatal sepsis caused by Ralstonia pickettii

2008

e describe the clinical case of apremature newborn, born at 26weeks by cesarean delivery, followed inthe neonatal intensive care unit. Themother was diabetic with adequate con-trol during pregnancy.Neonatal weight was 930 g;APGAR score 3 at 1 minute and 8 at 5minutes. She received forced ventilationby endotracheal tube and parenteralnutrition by a central venous catheter.She was treated with ampicillin for thefirst 20 days of life. At 25 days, apneaand bradychardia episodes occurredwith a progressive increment in sever-ity and frequency. Leukocytes, C-re-active protein, cerebral echography,and echocardiogram were normal.Oralfeeding was transiently stopped and rani-tidine treatment was starte…

Prevalence and risk factors for sensorineural hearing loss: Western Sicily overview.

2013

The objective of this work was to evaluate the prevalence of sensorineural hearing loss (SNHL) and distribution of the main risk factors associated to it focusing on their role in the development of deafness and their interaction. We performed a global audiological assessment (through TEOAE, tympanometry and ABR) in 508 infants at risk studying the main risk factors reported by Joint Committee on Infant Hearing (2007). Fifty-one infants (10.03 %) were diagnosed with SNHL (45 bilateral and 6 unilateral) with a mean hearing threshold of 87.39 ± 28.25 dB HL; family history of hearing impairment (HI) and TORCH infections indicated independent significant risk factors (P < 0.00001 and P = 0.0…
