First records of Anacaena lutescens (Stephens, 1829) and Cercyon littoralis (Gyllenhal, 1808) from Turkey (Coleoptera, Hydrophilidae)

Ümit Incekara; Abdullah Mart; Orhan Erman

Abstract Two Hydrophilid species (water beetles) are described as new to the Turkish fauna: Anacaena lutescens (Stephens, 1829) and Cercyon littoralis (Gyllenhal, 1808). Both were found at high altitiudes in the Black Sea region. The descriptions are supported by scanning electron microscope photographs.

Abdullah Mart; Ümit Incekara; Orhan Erman

A new species, Laccobius (Dimorpholaccobius) hopaensis sp. n. is described and Laccobius (Dimorpholaccobius) hoberlandti Gentili, 1982 is recorded from Turkey for the first time. In addition, a list of Laccobius Erichson, 1837 species known from Turkey is presented.

New water mites of the family Hygrobatidae (Acari, Hydrachnidia) from Turkey.

Yunus Esen; Vladimir Pešić; Orhan Erman; Yücel Kaya

Abstract In this study, the findings of three water mite species of the family Hygrobatidae collected from different streams in Turkey were evaluated. Hygrobates (s. str.) anatolicus Esen & Pešić, sp. n. is described as new for science. Hygrobates (Rivobates) diversiporus Sokolow, 1927 and Atractides (s. str.) nikooae Pešić, 2004, which were illustrated and thoroughly discussed, are new records for the Turkish fauna.

Ümit Incekara; Abdullah Mart; Orhan Erman

A new species of Helophorus Fabricius, 1775 is described from Erzurum, northeastern Turkey: Helophorus erzurumicus. In addition, distributional and morphological notes on H. ponticus Angus, 1988 are presented.

Two new water mite species of the genus Lebertia (Acari: Hydrachnidia: Lebertiidae) from Turkey

Yunus Esen; Sibel Dilkaraoğlu; Orhan Erman; Reinhard Gerecke

Two water mite species new to science are described of the genus Lebertia, collected from running waters and springs in Eastern Anatolia, Turkey. Lebertia (Brentalebertia) anatolica Esen and Dilkaraoglu, sp.nov. as the fourth known species of the subgenus Brentalebertia Gerecke, 2008 and Lebertia (s. str.) erzurumensis Esen and Erman, sp. nov. as a sister species of L. pusilla. Lebertia (s. str.) subtilis Koenike, 1902 is recorded for the first time after the original description from Switzerland. It was found in a high-altitude spring, rich in gravel substrata and moss vegetation. http://www.zoobank.org/urn:lsid:zoobank.org:pub:6D5992C0-CB77-4651-B93C-17AA5015F027


ZooKeys | 2018

First record of larvae of the water mite Hydrachna processifera Piersig, 1895 from Turkey (Acari, Hydrachnidia, Hydrachnidae)

Medeni Aykut; Andrzej Zawal; Yunus Esen; Orhan Erman

Abstract Larvae of water mite Hydrachna processifera Piersig, 1895 (Acari, Hydrachnidiae) were reported on diving beetles Dytiscus marginalis Linnaeus, 1758 (Coleoptera, Dytiscidae) from Turkey. The redescription of the larva was made. Earlier, the larva H. processifera was described as H. inermis, but it was subsequently synonymized with H. processifera. The larva of H. processifera is a new record for the Turkish fauna. All larvae of H. processifera were found on the mesosternum of the one specimens (prevalence = 16.7%).

Ellagic acid impedes carbontetrachloride-induced liver damage in rats through suppression of NF-kB, Bcl-2 and regulating Nrf-2 and caspase pathway

Abdullah Aslan; Ozlem Gok; Orhan Erman; Tuncay Kuloglu

The use of natural antioxidants instead of conventional treatments is considered effective and safe alternative therapy for hepatotoxicity. Ellagic acid (EA) is a strong antioxidant matter having protecting effect particularly on the liver. Hepatotoxic compounds can cause very heavy damage. Among these chemical hepatotoxins, CCl4 are responsible for the trichloromethyl radical resulting from biotransformation of the liver. The aim of this study was to examine whether EA plays a protective role against to liver damage induced with carbon tetrachloride (CCl4) in rats. In this study, 36 male wistar albino (n = 36, 8 weeks old) rats were used. The rats were distributed into 4 groups, and 9 rats involved in each group. The groups were: (i) Control Group: Fed with standard diet; (ii) EA Group: Fed with standard diet + EA; (iii) CCl4 Group: Fed with standard diet + CCl4; (iv) CCl4 + EA Group: Fed with standard diet + CCl4 + EA. After 8 weeks, the rats were decapitated and the liver tissue were examined. As a result; EA application created a significant difference (p < 0.05) on caspase-3, bcl-2, NF-kB and Nrf-2 expression in the CCl4 + EA group in comparison to CCl4 group. Caspase-3 and Nrf-2 expression levels were increased in the CCl4 + EA group in comparison to CCl4 group, but bcl-2 and NF-kB expression levels were decreased. In TUNEL assay examinations, apoptotic index ratio was decreased in the CCl4 + EA group in comparison to CCl4 group. These results show that EA reduce liver damage ratio at wistar albino rats and also these results suggest that ellagic acid may be a potentially protective drug against to liver damage in future.
