First barcode-assisted annotated checklist of owlflies (Neuroptera, Myrmeleontidae, Ascalaphidae) of Georgia with the first record of genus Deleproctophylla Lefèbvre, 1842

The present study aims to provide an updated checklist of the owlfly subfamily Ascalaphidae Lefèbvre, 1842, with the first records of the genus Deleproctophylla Lefèbvre, 1842, from the country. The new records give an improved understanding of owlfly distribution within the country. The record of the genus Deleproctophylla in Georgia is based on a single female specimen of D. australis (Fabricius, 1787)

Sleep-wake patterns and sleep quality in urban Georgia

Sleep problems represent a worldwide health concern but their prevalence and impacts are unknown in most non-European/North American countries. This study aimed to evaluate sleep-wake patterns, sleep quality and potential correlates of poor sleep in a sample of the urban Georgian population

Picking pearls from the Silk Road: Insights into the spider (Arachnida, Araneae) diversity in Georgia from the Caucasus Barcode of life project. Part II

Abstract Spiders collected during field trips and by spontaneous hand collection throughout Georgia between the years 2006 and 2023 were determined to species and partially assisted by genetic barcoding of the COI gene. Among the resulting 297 species, 100 species, 25 genera, and 1 family were recorded from Georgia for the first time, of which 18 species and 5 genera were recorded for the first time from the entire Caucasus. Of the 283 barcoded specimens representing 150 species, 26 were barcoded for the first time. 140 diagnostic drawings of 76 preserved specimens, along with photos of 15 preserved (Supplementary File) and one alive species, are provided. Baryphyma proclive (Simon, 1884), Pritha pallida (Kulczyński, 1897), and Zelotes khostensis Kovblyuk & Ponomarev, 2008 are indicated as the species with an Italo-Caucasian disjunctive distribution

Sleep-wake patterns and sleep quality in urban Georgia

OBJECTIVES: Sleep problems represent a worldwide health concern but their prevalence and impacts are unknown in most non-European/North American countries. This study aimed to evaluate sleep-wake patterns, sleep quality and potential correlates of poor sleep in a sample of the urban Georgian population. METHODS: Analyses are based on 395 volunteers (267 females, 128 males, aged 20-60 years) of the Georgia Somnus Study. Subjects completed the Pittsburgh Sleep Quality Index (PSQI) and the Beck Depression Inventory-Short Form. Sociodemographic information and self-reported height and weight were collected. RESULTS: 43% of subjects had poor sleep quality (PSQI > 5). Further, 41% had low sleep efficiency, 27.6% slept 6 hours or less, 32.4% went to bed after midnight, 27.6% snored, 10.6% were taking sleep medication, and 26.8% had sleep maintenance problems as occurring three or more times a week. The latest bedtime, rise time, and gender effect on these variables were found in the age group 20-29 years. PSQI global score showed a significant age but not gender difference. The economic status and the depression score were two significant predictors of sleep quality. CONCLUSIONS: Poor sleep quality has a high prevalence and is strongly linked to the economic status. Study findings call for a global assessment of sleep problems in countries where sleep disturbances represent an insufficiently recognized public health issue

Picking pearls from the Silk Road: Insights into the spider (Arachnida, Araneae) diversity in Georgia from the Caucasus Barcode of Life (CaBOL) project. Part III

The present study contains information about a small number of spiders collected between 2018 and 2023. The spiders were determined to species level and partially assisted by genetic barcoding of the COI gene. Among the resulting 33 species, 23 species and three genera, are recorded from Georgia for the first time, of which 11 are new records for the entire Caucasus. Of the 26 barcoded specimens representing 18 species, six species (Agroeca maculata L. Koch, 1879; Aituaria eriashvilii (Marusik, 1987); Evippa sjostedti Schenkel, 1936; Lathys cf. lehtineni Kovblyuk, Kastrygina & Omelko, 2014; Zelotes segrex (Simon, 1878); Lathys lehtineni Kovblyuk, Kastrygina & Omelko, 2014; Maculoncus obscurus Tanasevitch, Ponomarev & Chumachenko, 2016) are barcoded for the first time. In addition, 12 new regional records for 10 species are provided. The collecting information for each record is provided in detail, together with a discussion of the barcoding results and remarks, supported by 48 diagnostic drawings of 22 first-recorded species. A potential synonymy of Pelecopsis odontophora (Kulczyński, 1895) with P. parallela (Wider, 1834) and Bassaniodes loeffleri (Roewer, 1955) with B. pseudorectilineus (Wunderlich, 1995) is discussed

Modulation of Hyperpolarization-Activated Inward Current and Thalamic Activity Modes by Different Cyclic Nucleotides

The hyperpolarization-activated inward current, Ih, plays a key role in the generation of rhythmic activities in thalamocortical (TC) relay neurons. Cyclic nucleotides, like 3′,5′-cyclic adenosine monophosphate (cAMP), facilitate voltage-dependent activation of hyperpolarization-activated cyclic nucleotide-gated (HCN) channels by shifting the activation curve of Ih to more positive values and thereby terminating the rhythmic burst activity. The role of 3′,5′-cyclic guanosine monophosphate (cGMP) in modulation of Ih is not well understood. To determine the possible role of the nitric oxide (NO)-sensitive cGMP-forming guanylyl cyclase 2 (NO-GC2) in controlling the thalamic Ih, the voltage-dependency and cGMP/cAMP-sensitivity of Ih was analyzed in TC neurons of the dorsal part of the lateral geniculate nucleus (dLGN) in wild type (WT) and NO-GC2-deficit (NO-GC2−/−) mice. Whole cell voltage clamp recordings in brain slices revealed a more hyperpolarized half maximal activation (V1/2) of Ih in NO-GC2−/− TC neurons compared to WT. Different concentrations of 8-Br-cAMP/8-Br-cGMP induced dose-dependent positive shifts of V1/2 in both strains. Treatment of WT slices with lyase enzyme (adenylyl and guanylyl cyclases) inhibitors (SQ22536 and ODQ) resulted in further hyperpolarized V1/2. Under current clamp conditions NO-GC2−/− neurons exhibited a reduction in the Ih-dependent voltage sag and reduced action potential firing with hyperpolarizing and depolarizing current steps, respectively. Intrathalamic rhythmic bursting activity in brain slices and in a simplified mathematical model of the thalamic network was reduced in the absence of NO-GC2. In freely behaving NO-GC2−/− mice, delta and theta band activity was enhanced during active wakefulness (AW) as well as rapid eye movement (REM) sleep in cortical local field potential (LFP) in comparison to WT. These findings indicate that cGMP facilitates Ih activation and contributes to a tonic activity in TC neurons. On the network level basal cGMP production supports fast rhythmic activity in the cortex

National Identity for Breakfast : Food Consumption and the Everyday Construction of National Narratives in Estonia

Political debates on the Baltics, and in particular Estonia, have often pointed to "nationalisting" and exclusive narratives constructed at the institutional level. Accordingly, emphasis has been put on the lack of opportunities for Russians to integrate into an Estonian context. While acknowledging the shortfalls of the Estonian political project, this article contrasts these views in two ways. By emphasizing people's agency and their capacity to question, contrast, or even reject the identity markers proposed by Estonian official narratives, we maintain that the integration of Russians might be more advanced than insofar claimed by other studies. We then look at the way identities are lived in an everyday context by inhabitants of Estonia to counterpose national narratives proposed by the state and its political institutions, with the way people live and whether they accept these narratives. By doing this, we explore the role of the everyday in the reconstruction of national identity narratives, in which citizens actively participate in their individual capacity. We suggest that, from a James Scott "infrapolitics" perspective, these micro-actions have a fundamental role in the reshaping of a national identity and its acceptance among citizens.Peer reviewe
