Chicken turtles, Deirochelys reticularia (Latreille in Sonnini et Latreille) (Testudines: Emydidae) from Alabama, USA were infected by Spirorchis collinsi Roberts et Bullard sp. n. and Spirorchis cf. scripta. The new species is most easily differentiated from its congeners by the combination of having caeca that extend far beyond the genitalia, intercaecal genitalia positioned in the middle portion of the body, a testicular column that nearly abuts the caecal bifurcation, a cirrus sac positioned between the testes and ovary, a massive Mehlis' gland, an elongate, longitudinal metraterm that extends anteriad beyond the level of the ovary, a pre-ovarian genital pore, and a prominent, intercaecal Manter's organ. The specimens of S. cf. scripta differed from the holotype and published descriptions of Spirorchis scripta Stunkard, 1923 by several subtle morphological features, perhaps comprising intraspecific variation, but collectively warranted a detailed description herein. Based on examinations of the aforementioned specimens plus the holotype, paratypes and vouchers of morphologically-similar congeners, Spirorchis MacCallum, 1918 is emended to include the presence of oral sucker spines, a pharynx, lateral oesophageal diverticula ('plicate organ') and a median oesophageal diverticulum ('oeseophageal pouch'). Phylogenetic analysis of the nuclear large subunit rDNA (28S) recovered S. collinsi sister to Spirorchis picta Stunkard, 1923, > 99% similarity between S. cf. scripta and S. scripta, and a monophyletic Spirorchis MacCallum, 1918. No blood fluke infection has been reported previously from these drainages, Alabama, or this turtle species. This is the first new species of Spirorchis to be described from North America in 26 years., Jackson R. Roberts, Raphael Orélis-Ribeiro, Kenneth M. Halanych, Cova R. Arias, Stephen A.

As apex predators with a regulating effect on interspecific competitors and prey demographics, monitoring of spotted hyaena (Crocuta crocuta) population trends can provide a reliable indicator of ecosystem health. However, the ability of current survey techniques to monitor carnivore densities effectively are increasingly questioned. This has led recent studies to advocate increased application of spatial capture-recapture (SCR) methods to estimate population density for large carnivores. We reviewed the literature regarding methods used to estimate population density for spotted hyaena since 2000. Our review found that SCR methods are underutilised for estimating spotted hyaena density, with only eight published studies (13% of articles assessed) using an SCR approach. Call-in surveys were the most frequently used method, featuring in 47% of studies. However, 63% of studies that used call-in surveys could not estimate a site-specific calibration index. The calibration index estimates the distance and rate at which the focal species responds to audio lures and, as response rates are impacted by site-specific ecological and environmental factors, studies that could not calibrate this index are likely inaccurate. Further application of SCR techniques will allow more robust estimation of spotted hyaena density, reducing uncertainty and potential overestimation that limit inference from existing survey methods.
Mediální dialog ztrácí některé rysy přirozeného dialogu tváří v tvář, který leží v jeho půdorysu, a získává rysy další, neboť komunikace tu přestupuje přes hranice primární řečové situace. Televizní dialog je dialog veřejný, který se vede před diváckým publikem a pro toto publikum. Divák je nejen svědkem, ale pravým cílem, k němuž je dialog směrován. Stať analyzuje komunikační situaci, při níž jsou ve studiu přítomni redaktor a dva hosté, představitelé různých profesí a názorových proudů (ekonom a ekoložka) i různých stanovisek к určité otázce (globalizace). Redaktor se obrací s otázkami střídavě к oběma. aby je vzájemně konfrontoval a spor vyhrotil. Dotazovaní hosté se snaží nejen odpovídat na otázky redaktora (to je jejich základní role v interview), ale i zpochybňovat či přímo vyvracet odpovědi druhého z hostí (role často neméně důležitá). Hosté komunikují nejen s redaktorem, ale komunikují i mezi sebou navzájem, ať už skrytě, či zjevně, s cílem získat diváka na svou stranu.

Hlavným cieľom výskumnej štúdie bolo preskúmanie vzťahov medzi nerozhodnosťou, akademickou prokrastináciou a úzkosťou. Výskumu sa zúčastnilo 296 vysokoškolských študentov (M=21,06; SD=1,52). Údaje boli získané pomocou slovenskej verzie Škály nerozhodnosti, Layovej škály prokrastinácie pre študentov a Beckovho dotazníka úzkosti. Bol potvrdený stredne silný signifikantný vzťah medzi nerozhodnosťou a úzkosťou a silný signifikantný vzťah medzi nerozhodnosťou a akademickou prokrastináciou. Medzi akademickou prokrastináciou a úzkosťou bol zistený signifikantný, ale veľmi slabý vzťah. Na varianciu prokrastinácie pôsobí najmä nerozhodnosť, relatívny vplyv úzkosti je slabší. Nerozhodnosť je predikovaná v porovnateľnej miere prokrastináciou, ako i úzkosťou. Neboli preukázané štatisticky významné rodové rozdiely v miere nerozhodnosti a akademickej prokrastinácie. and The main aim of the research study was to explore the relationships between indecisiveness, academic procrastination and anxiety. The research sample consisted of 296 university students (mean age=21,06; SD=1,52), who completed the Slovak adaptations of the Indecisiveness Scale, the Lay's Procrastination Scale for Students and the Beck Anxiety Inventory. A significant moderate correlation was found between indecisiveness and anxiety, as well as a significant strong correlation between indecisiveness and academic procrastination. A significant but very weak relationship was found between academic procrastination and anxiety. Indecisiveness explained more variance in academic procrastination than anxiety. Indecisiveness was predicted by procrastination and anxiety to a similar degree. No gender differences were detected in the levels of indecisiveness or academic procrastination.
a1_Coeuritrema Mehra, 1933, previously regarded as a junior subjective synonym of Hapalorhynchus Stunkard, 1922, herein is revised to include Coeuritrema lyssimus Mehra, 1933 (type species), Coeuritrema rugatus (Brooks et Sullivan, 1981) comb. n., and Coeuritrema platti Roberts et Bullard sp. n. These genera are morphologically similar by having a ventral sucker, non-fused caeca, two testes, a pre-testicular cirrus sac, an intertesticular ovary, and a common genital pore that opens dorsally and in the sinistral half of the body. Phylogenetic analysis of the D1-D3 domains of the nuclear large subunit ribosomal DNA (28S) suggested that Coeuritrema and Hapalorhynchus share a recent common ancestor. Coeuritrema is morphologically most easily differentiated from Hapalorhynchus by having ventrolateral tegumental papillae and a definitive metraterm that is approximately 3-7× longer than the uterus. Coeuritrema comprises species that reportedly infect Asiatic softshell turtles (Testudines: Trionychidae) only, whereas Hapalorhynchus (as currently defined) comprises blood flukes that reportedly infect those hosts plus North American musk turtles (Sternotherus Bell in Gray) and mud turtles (Kinosternon Spix), both Kinosternidae, North American snapping turtles (Chelydridae), Asiatic hard-shelled turtles (Geoemydidae) and African pleurodirans (Pelomedusidae). Coeuritrema platti sp. n. infects the blood of Chinese softshell turtles, Pelodiscus sinensis (Wiegmann), cultured in the Da Rang River Basin (Phu Yen Province, Vietnam). It differs from C. lyssimus by having a narrow hindbody (< 1.6× forebody width), ventrolateral tegumental papillae restricted to the hindbody, a short cirrus sac (< 10% of corresponding body length), a transverse ovary buttressing the caeca, a short, wholly pre-ovarian metraterm (~ 10% of corresponding body length), and a submarginal genital pore., a2_It differs from C. rugatus by having small ventrolateral tegumental papillae, testes without deep lobes, and a Laurer's canal pore that opens posterior to the vitelline reservoir and dorsal to the oviducal seminal receptacle. The new species is only the second turtle blood fluke reported from Vietnam., Jackson R. Roberts, Raphael Orélis-Ribeiro, Binh T. Dang, Kenneth M. Halanych, Stephen A.

Clear cell renal cell carcinoma (ccRCC) is very common and accounts for most kidney cancer deaths. While many studies are being conducted in finding the prognostic signatures of ccRCC, we believe that ferroptosis, which involves programmed cell death dependent on iron accumulation, has therapeutic potential in ccRCC. Recent research has shown that long noncoding RNAs (lncRNAs) are involved in ferroptosis-related tumour processes and are closely related to survival in patients with ccRCC. Hence, in this study we aim to further explore the role of ferroptosis-related lncRNAs (FRLs) in ccRCC, hoping to establish a signature to predict the survival outcome of ccRCC. We analysed transcriptome data from The Cancer Genome Atlas database (TCGA) and ferroptosis-related genes (FRGs) from FerrDb to identify FRLs using Pearson’s correlation. Lasso Cox regression analysis and multivariate Cox proportional hazards models screened seventeen optimal FRLs for developing prognostic signatures. Kaplan-Meier survival curves and ROC curves were then plotted for validating the sensitivity, specificity, and accuracy of the identified signatures. Gene Set Enrichment Analysis and CIBERSORT algorithm were deployed to explore the role of these FRLs in the tumour microenvironment. It was concluded that these models demonstrate excellent performance in predicting prognosis among patients with ccRCC, also indicating association with the clinicopathologic parameters such as tumour grade, tumour stage and tumour immune infiltration. In conclusion, our findings provide novel insights into ferroptosis-related lncRNAs in ccRCC, which are important targets for investigating the tumorigenesis of ccRCC.
Four new species of Acanthobothrium van Beneden, 1850 are described from guitarfish, Rhynchobatus cf. djiddensis (Forsskål), collected from the Gulf of Oman and Persian Gulf. Acanthobothrium janineae sp. n., a category 1 species, differs from all congeners in category 1 by having a long vagina extending into the vas deferens and different, proglottid and testis number except Acanthobothrium hypermekkolpos Fyler et Caira, 2010. Acanthobothrium fylerae sp. n., a category 1 species, can be differentiated by a combination of characters including the total length, proglottid and testis number, cirrus sac shape, and the length of the vagina and ovarian lobes. Both new species are similar to A. hypermekkolpos reported from Rhynchobatus laevis (Bloch et Schneider) from Australia in their scolex proper length, hook size and muscular pad, respectively. Acanthobothrium asrinae sp. n., a category 1 species, differs from other category 1 species by the shape of its hooks and the position of the tubercle at the mid-length of the axial prongs; in this respect it resembles A. bartonae Campbell et Beveridge, 2002 reported from Australia. Acanthobothrium jamesi sp. n. is among six category 1 species with post-ovarian testes. It differs from these species by total length, proglottid and testis number and the extension of the ovarian lobes. Although it is thought that R. djiddensis occurs in the region, the identities of the hosts of the newly described Acanthobothrium species await verification. There are two forms of host in the region and were designated as R. cf. djiddensis 1 and R. cf. djiddensis 2. More taxonomic work and the use of molecular techniques are needed to resolve the true identity of the host species., Loghman Maleki, Masoumeh Malek, Harry W. Palm., and Obsahuje bibliografii
This review updates the information on the actual status and distribution of freshwater gobies in Bosnia and Herzegovina. The available literature has been critically reviewed to provide more complete and up-to-date information. Consequently four species are proposed for removal from the national checklist, given the lack of any data to support their presence: Knipowitschia panizzae, Pomatoschistus microps, Proterorhinus marmoratus and Zosterisessor ophiocephalus. Therefore, the freshwater gobiid fauna is confirmed to include seven species from six genera. The Adriatic Sea basin (Neretva River catchment) is inhabited by three endemic species: Knipowitschia radovici, Orsinigobius croaticus and Ninnigobius canestrinii, while the Black Sea basin (Danube River catchment) is inhabited by the invasive species: Babka gymnotrachelus, Neogobius fluviatilis, Neogobius melanostomus and Ponticola kessleri. However, due to the possibility of misidentify the finding of B. gymnotrachelus is questionable and needs confirmation. Distribution of both endemic Knipowitschia and Orsinogobius species is restricted to small areas in the lower Neretva River catchment on both sides of the Croatia-Bosnia and Herzegovina border. The vulnerability of these species is discussed, and the IUCN conservation and units meriting conservation attention were identified. The invasive character of other species is highlighted. This review indicates that the knowledge on the Bosnia-Herzegovinian freshwater gobiid fauna is still far from complete, hence this up-to-date checklist can serve as a basis for further ecological and zoogeographical studies. For better species inventory, finer scale distribution surveys are needed, followed by detailed morphological, molecular phylogenetic and ecological studies.
Text v několika ohledech pojednává vypravěčské gesto v díle Milana Kundery. Vypravěčským gestem lze sjednotit a tematizovat jinak žánrově odlišné texty (poezie, divadelní hry, eseje, romány), takto lze číst texty Milana Kundery jako určitý rukopis, jako jistou reflexi řeči. Nejprve bylo poukázáno na Kunderovo pojetí básnické řeči, kterou Kundera představuje na básních Vítězslava Nezvala. Zde si Kundera všímá zejména antropomorfního tahu, neboť básně mají v jeho tehdejším pohledu proměnit odcizený svět fantómů na svět věcí, které nepostrádají lidský rozměr. Ozvuk demiurgického rázu básnického slova lze sledovat na Kunderově pojetí vyprávění, na jeho základním rozlišením mezi vypravěče a postavy. Z této perspektivy se zdá, že vypravěč okupuje nedobytný mocenský post. Ve studii o Vančurovi vyzdvihuje Kundera pojem zlyrizované prózy. Kunderovu představu o próze kontrastuji s tradicí nového románu (Robbe-Grillet) a francouzského strukturalismu (Barthes). Poté vyznačuji Kunderovu poetiku v napětí metaforického a metonymického období. V závěru je předložena teze, podle níž je Kunderova opozice mezi románem a lyrikou do značné míry nedržitelná, neboť románový svět Milana Kundery je lyrizován. and This article considers several aspects of the geste du narrateur in the works of Milan Kundera(b. 1929). With the geste du narrateur it is possible to unite and thematize texts of different genres(verse, drama, novels, and essays), and it is possible to read Kundera’s works as a definitevoice, as a certain reflexion of speech. First, Kundera’s conception of poetic language is consideredby looking at his analysis of poems by Vítězslav Nezval (1900–1958). Kundera considersanthropomorphic devices in particular, because the poems are, in his view, meant to transformthe alienated world of phantoms into a world of objects that have a human dimension. An echoof the demiurge nature of the poetic word is audible in Kundera’s conception of the narrative, inhis fundamental distinction between narrator and character. From this perspective it seems thatthe narrator occupies an invincible position of authority. Interpreting Kundera’s 1960 book onVladislav Vančura (1891–1942) the article pays special attention to the concept of lyrical prose.It contrasts Kundera’s idea of fiction with the tradition of the nouveau roman (Robbe‑Grillet)andNew Criticism. It then characterizes Kundera’s style by the tension between his metaphoricaland metonymous periods, and concludes that Kundera’s decision to set prose and the lyrical inopposition to each other is largely untenable, because his fictional world is in fact lyricized.
