A light- and electron microscopic study of primordial germ cells in the zebra fish (Danio rerio)

Yön Ertuğ, Nazan Deniz (SOC BIOLGIA CHILE, 2012)

In sexually reproducing organisms, primordial germ cells (PGCs) give rise to the cells of the germ line, the gametes. In many animals, PGCs are set apart from somatic cells early during embryogenesis. This study explores ...
Alkaline protease production of Bacillus cohnii APT5

Tunç, Kenan (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2012)

An obligate alkaliphilic Bacillus strain was isolated from a soil sample and identified as Bacillus cohnii APT5 based upon phylogenetic and phenotypic analyses. The optimum growth pH of B. cohnii APT5 was 10.0. B. cohnii ...
Copper bioremoval by novel bacterial isolates and their identification by 16S rRNA gene sequence analysis

Tunç, Kenan (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2012)

Copper-tolerant bacteria were isolated from soil samples taken from a region where metal industries are located. After selecting 2 isolates with relatively higher bioremoval efficiency, the effects of increasing copper ...
Developmental Toxicity of (4S)-2-(4-hydroxy-3-methoxyphenyl)thiazolidine-4-carboxylic acid in Zebrafish (Danio rerio)

Akbulut, Cansu; Burcu Ozturk; Genç Bilgiçli, Hayriye; Zengin, Mustafa; Yön Ertuğ, Nazan Deniz (INST TECNOLOGIA PARANA, 2017)

(4S)-2-(4-hydroxy-3-methoxyphenyl)thiazolidine-4-carboxylic acid is new synthesized substance obtained from cysteine and valine. Thiazolidine derivates have important biological responses so scientists work intensively on ...
Identification of Primordial Germ Cells: Cytological, Histological and Immunohistochemical Aspects

Yön Ertuğ, Nazan Deniz; Akbulut, Cansu (INST TECNOLOGIA PARANA, 2015)

Primordial germ cells (PGCs) constitute an embryonic cell type that migrate to gonadal precursors and form the gametes. In many animals, PGCs are set apart from somatic cells early during embryogenesis. These cells migrate ...
Micromorphological study of Centaurea L. (Asteraceae); some taxa of eight sections analysed with scanning electron microscopy and light microscopy

Birol Baser; Sukru Hayta; Gulden Dogan; Sezgin Celik; Aksoy, Hüseyin (SPRINGER, 2019)

This study deals with the pollen morphological characterization of 36 taxa (Sections; Cheirolepis 3, Cynaroides 14, Rhizocalathium 5, Grossheimia 3, Chartolepis 3, Pseudophaeopappus 1, Plumosipappus 1 and Phaeopappus 6) ...
New and firstly recorded oribatid mites from Turkey

Baran, Şule (WALTER DE GRUYTER GMBH, 2015)

A new species belonging to genus Ctenobelba (Caucasiobelba) by Subias & Shtanchaeva, 2010 is described and a firstly recorded species of genus Papillacarus Kunst, 1959 is redescribed using SEM micrographs.
Ovarian follicle structure of Zebrafish (Danio rerio Hamilton) after poly(2-ethyl-2-oxazoline) exposure

Yön Ertuğ, Nazan Deniz; Olgun, Uğursoy; Akbulut, Cansu (NATL INST SCIENCE COMMUNICATION-NISCAIR, 2016)

Poly(2-oxazoline)s have been widely known for their biomedical applications. They mimic natural systems and are generally used as liposomes, drug and gene delivery modules and also as pseudopeptides. In this study, effects ...
Phylogenetic and Taxonomic Relationship of Turkish Wild and Cultivated Emmer (Triticum turgidum ssp. dicoccoides) Revealed by iPBS-Retrotransposons Markers

Memim Arystanbekkyzy; Muhammad Azhar Nadeem; Husnu Aktas; Mehmet Zahit Yeken; Nusret Zencirci; Muhammad Amjad Nawaz; Fawad Ali; Muhammad Sajjad Haider; Tunç, Kenan; Gyuhwa Chung; Faheem Shehzad Baloch (FRIENDS SCIENCE PUBL, 2019)

Wild emmer (Triticum turgidum ssp. dicoccoides) is the progenitor of cultivated wheat. Turkey is the main center of wheat and plays a vital role in the spread of various crops among the continents. Karacadag region is ...
Quadroppia (Coronoquadroppia) sezeki sp n. (Acari: Oribatida), a new soil mite from Turkey

Baran, Şule (VERSITA, 2009)

A new soil mite species, Quadroppia (Coronoquadroppia) sezeki sp. n., is described. Adult mites were recorded from moss under a pine tree from a pine forest. The new species differs from the other species of the subgenus ...
Review of the family Perlohmanniidae (Acari: Oribatida) with description of a new species from Turkey

Nusret Ayyildiz; Luis S. Subias; Baran, Şule (WALTER DE GRUYTER GMBH, 2016)

A review of the family Perlohmanniidae Grandjean, 1954 (Acari: Oribatida) is provided with description of a new species: Perlohmannia (Perlohmannia) turcica from Turkey. Identification key to known species of the family ...
Ultrastructural evaluation of oocyte envelopes of zebrafish (Danio rerio) (Hamilton, 1822) after TiO2 nanoparticle exposure

Akbulut, Cansu; Tugba Kotil; Yön Ertuğ, Nazan Deniz (INST BIOLOSKA ISTRAZIVANJA SINISA STANKOVIC, 2018)

Titanium dioxide (TiO2) is one of the most widely used nanoparticles, and aquatic organisms are especially exposed to it. To examine reproductive toxicology, zebrafish were exposed to different concentrations (1, 2 and 4 ...
