Length-Weight Relationships For 21 Fish Species Caught In The Argolikos Gulf (Central Aegean Sea, Eastern Mediterranean), Kostas Kapiris, Dimitris Klaoudatos

Turkish Journal of Zoology

The length-weight relationship for both sexes of 21 fish species caught in Argolikos Gulf (central Aegean Sea, eastern Mediterranean), using a variety of fishing gear, was estimated for the first time. Fishing took place between August 2007 and August 2008, and the fishing gear used included gill and trammel nets, long lines, and beach seines from 58 inshore fishing vessels. Individuals caught by trammel nets were usually longer and heavier than those collected by other fishing gear. The allometric coefficient (b) for the majority of species (59%) was statistically significantly higher than 3.0, indicating positive allometry between length and weight …

Alterations In Ion Levels Of Freshwater Fish Oreochromis Niloticus Following Acute And Chronic Exposures To Five Heavy Metals, Gülüzar Atli, Mustafa Canli

Turkish Journal of Zoology

Freshwater fish, Oreochromis niloticus, were individually exposed to 0, 0.1, 0.5, 1.0, and 1.5 µg/mL of Cu^{2+}, Cd^{2+}, Cr^{6+}, Ag^+, and Zn^{2+} for 96 h (acute) and 0.05 µg/mL concentrations of the same metals for 0, 5, 10, 20, and 30 days (chronic). Following each period, metal accumulation and ion levels (Na^+, K^+, Ca^{+2}, and Mg^{+2}) were measured in the gills, kidneys, and muscles. Except for Ag^+, none of the metals killed the fish within 30 days. Silver killed all the fish within 16 days. With the exceptions of Ag^+ and Cr^{6+}, as their levels were below detection limits, metal …

Turkish Journal of Botany

The distribution and population size of 5 orchid species (Cephalanthera longifolia, Orchis simia, Platanthera bifolia, Dactylorhiza romana, and Ophrys scolopax) were studied in the southern Caucasus based on the individual numbers in a given area. The fruit set was recorded for the latter 3 species and compared in natural and control groups (pollinators prevented) for D. romana and O. scolopax. We compared the obtained fruit set values with those reported from other regions. The distributions of the 5 species were completely fragmented and the population sizes were extremely small. This is the first report of O. scolopax from the region, …

Double-Layer Mesh Hernioplasty For Repairing Umbilical Hernias In 10 Goats*, Jose M. Vilar, Juan A. Corbera, Giuseppe Spinella Jan 2011

Double-Layer Mesh Hernioplasty For Repairing Umbilical Hernias In 10 Goats*, Jose M. Vilar, Juan A. Corbera, Giuseppe Spinella

Turkish Journal of Veterinary & Animal Sciences

Umbilical hernias in goats are uncommon and can vary in their etiology and management. Hernioplasty can be done by closing the abdominal wall with a horizontal mattress pattern using absorbable sutures. However, larger defects (hernial ring size >3 cm) generally require the use of prosthetic materials that allow for a tension-free repair. In this study, 10 young female goats with umbilical hernias and hernial ring sizes ranging from 7-10 cm in width were treated using a double-layer polypropylene mesh. An ultrasonographic examination was performed to assess healing and connective tissue production.

Cicer Uludereensis Dönmez: A New Species Of Cicer (Chickpea) (Fabaceae) From Around The Fertile Crescent, Se Turkey, Ali̇ Aslan Dönmez

Turkish Journal of Botany

The genus Cicer L. includes an important crop plant, chickpea, which has been used as a protein source since prehistoric times. Specimens of a native Cicer have been collected and described from south-east Turkey. This new species, Cicer uludereensis Dönmez sp. nova, is distinct from a closely allied species, Cicer isauricum P.H.Davis, by its fine and more numerous teeth per leaflet, larger stipules, and narrower fruit with almost smooth seed surface. An illustration and a distribution map of the new species are provided and observations on the population are discussed.

Pollen Morphology Of The Genus Seseli L. (Umbelliferae) In Turkey, Ebru Doğan Güner, Hayri̇ Duman, Nur Münevver Pinar

Turkish Journal of Botany

Morphological features of pollen of 11 Turkish taxa belonging to the complex genus Seseli L. were examined using light and scanning electron microscopy. On the basis of exine sculpturing, 3 main types were recognised in Seseli: Type 1, rugulate at equator, psilate-perforate at pole; Type 2, striate-reticulate at equator, rugulate at pole; and Type 3, rugulate at equator, striate at pole. The study revealed that palynological characters display taxonomic significance in the genus.


Rare And Endemic Species: Why Are They Prone To Extinction?, Kani̇ Işik Jan 2011

Rare And Endemic Species: Why Are They Prone To Extinction?, Kani̇ Işik

Turkish Journal of Botany

A species is considered to be "rare" if it exhibits any one of the following attributes: (1) naturally occurs in a narrow geographical area, (2) occupies only one or a few specialised habitats, (3) forms only small population(s) in its range. An "endemic" species, however, grows naturally in a single geographical area, the size of which could be either narrow or relatively large. Not all endemic species are rare, just as not all rare species must necessarily be endemic. Many rare and/or endemic species exhibit one or more of the following attributes which make them especially prone to extinction: (1) …


Şerefeddin Sabuncuoğlu’S Drawings Of Gyneco-Obstetric Instruments, Nuri̇ Seli̇m Kadioğlu, Oya Ögenler, İlter Uzel Jan 2011

Şerefeddin Sabuncuoğlu’S Drawings Of Gyneco-Obstetric Instruments, Nuri̇ Seli̇m Kadioğlu, Oya Ögenler, İlter Uzel

Turkish Journal of Medical Sciences

The purpose of our study was to determine the contribution of Şerefeddin Sabuncuoğlu's achievement to bring gynecology to the modern knowledge level. The gynecological tools in the achievement of Serefeddin Sabuncuoğlu, who is the late period representative of classical medical paradigm, are examined in connection with the achievement of Zahravi, which belongs to the classical medical literature. It was determined that in the long time interval from Zahravi to Sabuncuoğlu a limited advancement occurred in medical knowledge, and that the differences between the achievements of the 2 doctors are important for reflecting the development between the 2 periods.

Turkish Journal of Medical Sciences

Urginea maritima (Um) is a plant native to especially Turkey and the Mediterranean area. In this study, we investigated whether Um extract exerted cytotoxicity on cancer cells. Materials and methods: We made various extracts of Um. These extracts in varying concentrations were added to an A549 NSCLC cell culture, alone or with gemcitabine and/or cisplatin. Growth inhibition was tested by the MTT assay and an Annexin V-FITC apoptosis detection kit Results: The onion Um extract (1 µg/mL) was more cytotoxic than cisplatin (1 µg/mL), gemcitabine (1 nm/mL), and leaf Um extract (1 µg/mL) with P < 0.001, P = 0.097, and P < 0.001, respectively. The efficacy of Um extract was further improved by the addition of an antioxidant cocktail to an IC_{50} value of 0.02 µg/mL. Conclusion: Um extract has been shown for the first time to be a strong candidate for drug development in solid tumors. Our studies continue to further define the specific antitumor compound(s) in this extract.
