Telomeric Repeats Of Immortal Hamster Cells, Nedi̇me Serakinci, Jorn Koch Jan 2000

Telomeric Repeats Of Immortal Hamster Cells, Nedi̇me Serakinci, Jorn Koch

Turkish Journal of Medical Sciences

We have analyzed telomeres in four hamster cell lines to investigate how telomeres look in cells grown past the Hayflick limit. In all four cell lines telomeric signals were seen after detection with two different sensitive in situ methods (FISH with PNA probes and PRINS). The telomeric signals were not very strong, suggesting that the repeats are very short, but were nevertheless clearly visible. With the PRINS technique, it was further possible to probe also for the presence of variant telomeric repeats at the chromosome ends. With some of the variant repeat probes, a difference was seen between probes for …

Turkish Journal of Medical Sciences

The success rate of a repaired torn meniscus is not more than 70%. Gene transfer to healing soft tissues appears to be a feasible method for manipulating the healing process. In an attempt to evaluate the feasibility of gene transfer to meniscal tissue we tried to transfer a reporter gene ( Echerichia coli, b-galactosidase gene) by using HVJ-liposome mediated gene transfer. After performing complete radial tear on the medial meniscus of fifty 14-week-old male Wistar rats, HVJ-liposomes with DNA were injected into the femoral artery of 15 rats and into the knee joint of the other 15 rats. HVJ- liposomes …

Contralateral White Noise-Induced Enhancement In The Guinea Pigõs Mlr: A Possible Link To Direc- Tional Hearing, Cüneyt Göksoy, Rezzan Utkuçal

Turkish Journal of Medical Sciences

The evoked potential components in a time window of 10-50 ms following an acoustic stimulus are called middle latency responses (MLRs). It is known that an amplitude enlargement occurs in guinea pig MLRs to monaural clicks when continuous white noise is applied to the other ear. This study was undertaken to see whether this enlargement is due simply to an overall, generalised effect of contralateral white noise (WN), or whether it may have some connection to directional hearing. Recordings were made from chronic guinea pig preparations with epidural electrodes in the temporal regions. Parallel to the results in the literature, …

A Detour In De Sitter Space While Calculating Vacuum Fluctuatins, M. Hortaçsu

Turkish Journal of Physics

{We study vacuum fluctuations of different gravitational waves by taking a detour in de Sitter space in the intermediate steps. We find finite contributions when the coupling constant is dimensionless, whereas null result persists in the cases with dimensional coupling constants. We also test our method for exactly solvable cases, and show that no spurious perturbative effects are introduced through our method.

Chaos In Closed Isotropic Cosmological Models With Steep Scalar Field Potential, A. V. Toporensky Jan 2000

Chaos In Closed Isotropic Cosmological Models With Steep Scalar Field Potential, A. V. Toporensky

Turkish Journal of Physics

The dynamics of closed scalar field FRW cosmological models is studied for several types of exponentially and more than exponentially steep potentials. The parameters of scalar field potentials which allow a chaotic behaviour are found from numerical investigations. It is argued that analytical studies of equation of motion at the Euclidean boundary can provide an important information about the properties of chaotic dynamics. Several types of transition from chaotic to regular dynamics are described.

Internal Photoemission Spectroscopy For A Ptsi/P-Si Schottky Junction, Bülent Aslan, Raşi̇t Turan Jan 2000

Internal Photoemission Spectroscopy For A Ptsi/P-Si Schottky Junction, Bülent Aslan, Raşi̇t Turan

Turkish Journal of Physics

Properties of internal photoemission in a PtSi-Si Schottky junction have been studied. The traditional Fowler plot of a detector's photoyield is found to be nonlinear for values close to the barrier height of the junction. It is shown that the model that takes all scattering mechanisms into account provides a successful description for the experimental results. It is also shown that the photoemission spectrum is independent of temperature in agreement with this model. The properties of detector's ambient influence the photoemission spectrum for wavelength of 3 $\mu$m or less. A strong loss in the detector's response is observed at around …

Late Devonian Conodont Fauna Of The Gümüşali Formation, The Eastern Taurides, Turke, Şenol Çapkinoğlu, İsmet Gedi̇k Jan 2000

Late Devonian Conodont Fauna Of The Gümüşali Formation, The Eastern Taurides, Turke, Şenol Çapkinoğlu, İsmet Gedi̇k

Turkish Journal of Earth Sciences

The Late Devonian Gümüşali formation of the eastern Taurides is a terrigenous-carbonate rock sequence about 600 m thick, consisting mainly of quartz sandstone, quartz siltstone, shale, and carbonate rocks. Palaeontologic and sedimentologic data mainly indicate a shallow subtidal depositional environment. This sequence generally represents the shallow-water polygnathid-icriodid biofacies, and contains conodont faunas that range from the Upper falsiovalis Zone into the Upper praesulcata Zone. However, they do not correlate well to the Late Devonian standard conodont zonation because of the lack of zonally diagnostic species and the irregular vertical distributions of the present taxa. Herein, 54 taxa belonging to nine …

Calcium And Phosphate Excretion In Preeclampsia, Pervi̇n Vural, Cemi̇l Akgül, Mukaddes Canbaz Jan 2000

Calcium And Phosphate Excretion In Preeclampsia, Pervi̇n Vural, Cemi̇l Akgül, Mukaddes Canbaz

Turkish Journal of Medical Sciences

In preeclampsia, alterations in renal function, electrolyte and water metabolism are common findings. Recent studies have suggested that preeclampsia is associated with hypocalciuria. A total of 59 women were included in the present study, 15 of whom were nonpregnant (NP) healthy women, 20 normotensive pregnant women (NTP), and 24 pregnant women with severe preeclampsia (PEP). We compared the three groups in terms of calcium and phosphate excretion, and some parameters of renal function such as serum urea, creatinine and creatinine clearance. Urinary calcium and phosphate levels in the PEP group were significantly lower than in the NP group (p< 0.001 and p< 0.01, respectively) and NTP group (p< 0.001 and p< 0.01, respectively). The serum urea levels were higher in the PEP group than in the NP and NTP (p< 0.001) groups. The same pattern of increase in the PEP group was valid for serum creatinine concentrations as compared with the NP (p< 0.01) and NTP (p< 0.001) levels. The glomerular filtration rate measured by creatinine clearance was lower in preeclamptic women than in normotensive pregnant women (p< 0.01). Patients with preeclampsia had significantly lower (p< 0.001) excretion of calcium than the NP and NTP groups (p< 0.001). Likewise, the phosphate levels were lower in women with preeclampsia than in the NP and NTP groups (p< 0.01). There was no correlation between parameters of renal function and calcium or phosphate excretion. Hypocalciuria and hypophosphateuria were found to be important features of severe preeclampsia and probably indirectly are related to the altered renal function seen in toxemia of pregnancy.
