Importance Of Calcium, Beri̇van Tandoğan, N. Nuray Ulusu
Importance Of Calcium, Beri̇van Tandoğan, N. Nuray Ulusu
Turkish Journal of Medical Sciences
Calcium is the most abundant mineral in the body. Calcium regulates many cellular processes and has important structural roles in living organisms. Skeletal muscle structure and function, polymerisation of fibrin and the conduction of impulses in the nervous system are regulated by calcium. Calcium is an important intracellular messenger in protozoa, plants, and animals. Calcium-transporting systems which are located in the plasma membrane and in the organelles, regulate the ionic concentration of calcium in various compartments according to the different demands of the physiological cycle and these systems upregulate calcium entry by the action of several hormones and calcium binding …

Turkish Journal of Medical Sciences
Bioluminescent imaging (BLI) is particularly well suited for imaging small animals, and it can be readily used by scientists who are already routinely using the luciferase gene as a reporter in cell-based assays. This strategy relies on ATP and an O_2 dependent photochemical reaction between luciferin and luciferase, resulting in the release of photons from only live cells. In BLI, the intensity of the light detected by the device is proportional to the intensity of light emitted and the relationship is quantitative. This study was performed to determine the sensitivity of BLI for the imaging of lung metastasis and breast …

Turkish Journal of Zoology
Seasonal activities of wolf spiders (Lycosidae) and ground spiders (Gnaphosidae) were studied in a meadow in Van between 30.11.1993 and 27.11.1994. Nineteen species belonging to 4 genera in Lycosidae and 11 species belonging to 6 genera in Gnaphosidae were identified by using pitfall traps. It was observed that male and female lycosids were active from February to July, subadult lycosids were active from May to July, female gnaphosids were active from March to October, male gnaphosids were active from February to October and subadult gnaphosids were active from February to November. In Lycosidae, adults comprised 31% of the population, the …
Morphometric, Karyotypic And Electrophoretic Analysis Of The Genus Apodemus Kaup, 1826 (Mammalia: Rodentia) In Thrace, Reyhan Çolak, Ercüment Çolak, Nuri̇ Yi̇ği̇t
Morphometric, Karyotypic And Electrophoretic Analysis Of The Genus Apodemus Kaup, 1826 (Mammalia: Rodentia) In Thrace, Reyhan Çolak, Ercüment Çolak, Nuri̇ Yi̇ği̇t
Turkish Journal of Zoology
Thirty-two specimens of Apodemus in Thrace were evaluated. Ten specimens of A. flavicollis and A. sylvaticus were karyotyped. Eighteen specimens were electrophoresed to determine patterns of the esterase enzyme system. Morphometric analysis showed that A. flavicollis and A. sylvaticus were the closest species in a comparison between A. agrarius. A. flavicollis and A. sylvaticus with the same karyotypic values of 2n = 48, Nfa = 46, and NF = 48. Patterns of the esterase enzyme system clearly separated A. flavicollis, A. sylvaticus and A. agrarius.

Turkish Journal of Veterinary & Animal Sciences
In this study, 30 geriatric dogs of different breeds, ages, and sex (15 females, 15 males) with suspected heart diseases were evaluated. All dogs were examined clinically, radiographically, and ultrasonographically. Thoracic radiography revealed cardiomegaly in 5 cases, right atrial dilatation in 7 cases, right ventricular dilatation in 5 cases, left atrial dilatation in 1 case, and left ventricular dilatation in 2 cases. 2-D echocardiography permitted direct visualization of pericardial effusion in 4 cases, cardiac hypertrophy in 1 case, right atrial dilatation in 1 case, vegetative mass lesion in 1 case, and cardiomegaly in 2 cases. Color Doppler Imaging were revealed …
Birds Of Nallıhan Bird Paradise (Central Anatolia, Turkey), Utku Perktaş, Zafer Ayaş
Birds Of Nallıhan Bird Paradise (Central Anatolia, Turkey), Utku Perktaş, Zafer Ayaş
Turkish Journal of Zoology
This study was conducted in Nallıhan Bird Paradise (Nallıhan, Ankara), which displays seasonal wetland characteristics. Within the scope of this study, a 12 month field study between August 2000 and July 2001 was carried out in order to determine the avifauna of Nallıhan Bird Paradise. One hundred and thirty bird species belonging to 14 orders and 41 families were recorded in the study area. It was concluded that this area was probably used by a total of 41 actual and/or possible bird species for breeding purposes.

Turkish Journal of Zoology
A total of 105 specimens of the genus Mus collected from Ankara, Bartın, Bolu, Düzce and Zonguldak in Turkey were biometrically evaluated. The isocitrate dehydrogenase enzyme system along with karyotypes of 37 specimens were analysed. The zygomatic index and the index of head plus body length/tail length were diagnostic characters for Mus domesticus and Mus macedonicus. Starch gel electrophoresis gave 2 loci (Idh-1 and Idh-2) for the isocitrate dehydrogenase enzyme system. Two alleles (Idh-1^{100} and Idh-1^{105}) of the Idh-1 locus were determined in M. domesticus and M. macedonicus. M. domesticus and M. macedonicus have the same karyological values 2n = …

A First Record (Knipowitschia Longicaudata (Kessler, 1877)) For The Fish Fauna Of Lake Manyas, Davut Turan, Selçuk Berber, E. Tarik Topkara, Bülent Verep
Turkish Journal of Zoology
Knipowitschia longicaudata is recorded for the first time from Lake Manyas. K. caucasica is known to live in Lake Manyas. Therefore, In order to determine whether the specimens of Knipowitchia collected from Lake Manyas were K. caucasica species or not, they were compared with K. caucasıca from Lake Eğirdir. The comparission of K. caucasica specimens from Lake Eğirdir with the specimens from Lake Manyas showed that those species were 2 distinct species of Knipowitchia. Statistical analyses revealed that our specimens were K. longicaudata. The systematic characteristics of this species were examined and then compared with the data of those reported …

Sexual Dimorphism In Podarcis Sicula Campestris, Milan Vogrin
Sexual Dimorphism In Podarcis Sicula Campestris, Milan Vogrin
Turkish Journal of Zoology
Morphometric characters (snout-vent length, tail length, head length, head width, and number of ventrals and gulars) were analysed in 58 male and 44 female Italian Wall Lizards, Podarcis sicula campestris, from the Adriatic coast of Slovenia. The Italian Wall Lizard is significantly dimorphic in most characters analysed. Males were significantly larger than females. No differences between sexes were found in the number of gulars, whereas the number of transversal rows of ventrals was significantly higher in females (27-30) than in males (24-27).
