Farklı partenogenetik aktivasyon sürelerinin fare embriyo gelişimi ve kalitesi üzerine etkileri

In the present study we investigate the effects of parthenogenetic activation on in vitro embryo development and quality in different activation periods. oocytes were obtained 14 hours after human chorionic gonadotropin (hCG) injection from superovulated B6D2F1 female mice then parthenogenetic activation started 18 hours after hCG injection. The oocytes were activated at different activation periods for 3, 4, 5 or 6 hours in 10 mM strontium chloride (SrCl2)+ 5 μg/mL-1 Cytohalasine B (CB) + 5 nM Trichostatin A (TSA) containing a Ca 2+ free Chatot Ziomek Brinster (CZB) activation medium, followed by further incubation for two hours at 37°C and 5% CO2 in embryo culturing medium + TSA. The results in the present study suggested that the parthenogenetic activation of the 6 hour activation period was found to be higher than at 3, 4 and 5 hours.Çalışmamızın amacı, partenogenetik aktivasyonda farklı aktivasyon sürelerinin in vitro embriyo gelişimi ve kalitesi üzerindeki etkilerinin araştırılmasıdır. Superovule B6D2F1 ırkı dişi farelere uygulanan insan koryonik gonadotropin (hCG) enjeksiyonundan 14 saat sonra oositler elde edildi ve 18 saat sonra partenogenetik aktivasyona başlandı. Oositler, 10 mM stronsiyum klorür (SrCl2) + 5 μg/mL-1 sitokalazin B (CB) + 5 nM trikostatin A (TSA) Ca 2+ içermeyen Chatot Ziomek Brinster (CZB) medyumu içerisinde 3, 4, 5 ve 6 saat bekletildi.

Analyzing Exchange Market Pressure Dynamics with Markov Regime Switching: The Case of Turkey

This study analyzes the dynamics of exchange market pressure in Turkey by employing the Markov regime switching model for the period from January 2006 to December 2019. Our findings show that there are two regimes in the foreign exchange market, characterized as low- and high-pressure periods. The domination of the high-pressure regime in the sample period indicates that depreciation pressure prevails in the Turkish foreign exchange market. During this regime, the pressure is aggravated by the rising inflation, credit growth, and VIX, and the falling of short-term external debt. Thus, in the presence of capital flows, the preferences of policy authorities regarding price stability and growth determine the course of the pressure. When these policy choices favor credit-driven growth, depreciation pressure in the foreign exchange market is exacerbated through the current account deficit

Relations of Religion Science and Philosophy

DergiPark: 326038trakyasobedIn this article we deal with religion, philosophy and science together almost first time. In religion philosophy relations theology and philosophy relations deserves attention and philosophy of religion or philosophical theology unites these two areas. Strict rasionalizm, critical rasionalism and fideism are main approaches for this reletionships. In relations of religion and science there are five approaches: conflict, dialog, differentiation, integration and islamization of science. Religion focuses why of events and the other areas how of eventsBu makalede din, bilim ve felsefe ilişkileri nerdeyse ilk defa üçü bir arada ele alınmaktadır. Din ve felsefe ilişkilerinde teoloji ile felsefe ilişkileri dikkat çekerken, bu iki alanı din felsefesi veya felsefi teoloji birleştirmektedir. Bu ilişkiye üçlü bir yaklaşım söz konusudur: katı akılcılık, fideizm ve eleştirel akılcılık. Din ve bilim ilişkilerinde dörtlü bir tasnif söz konusudur. Bunlar; çatışma, diyalog, farklılaşma ve entegrasyondur. Buna bir de bilginin İslamileştirilmesi eklenebilir. Dinin bilgi kaynağı vahiy, felsefenin bilgi kaynağı akıl ve bilimin bilgi kaynağı ise deney ve gözlemdir. Din olayların niçini üzerinde dururken, felsefe ve bilim nasılı üzerinde durmaktadı

A simple heart valve replacement technique which improves surgical time

Aim of the study: Different heart valve replacement techniques have been described in the literature. In the present study, a simple and very fast heart valve replacement technique is presented. Material and methods: In a two-year period, 87 patients with the diagnosis of mitral valve disease, aortic valve disease or combined valve disease underwent valve replacement performed by the same surgeon. In this technique, the valve was implanted with the valve clamped to the surgical dressing without the assistant holding it. Patients with coexisting surgical pathologies were excluded from the study. A control group was created among the patients who were operated on during the same time period by different surgeons with the assistant holding the prosthesis. Control group operations were done by conventional valve holding and suturing techniques. Results: Mean age of the patients was 61.6 ± 3.2 years. Mitral valve replacement (MVR) was done to 51 patients, aortic valve replacement (AVR) to 12 patients and both aortic and MVR to 24 patients. Aortic cross clamp duration was 30.7 ± 3.3 min for MVR, 34.8 ± 6.2 min for AVR and 69.1 ± 6.1 min for both valve replacements. Aortic clamping durations were significantly higher in the conventional implantation technique. Discussion: The described technique has many advantages such as short myocardial ischemia duration, better exposure of the surgical field and facilitation of assistance. © 2014 Termedia Sp. z o.o.

A Novel Blind Adaptive Beamformer with Robustness against Mutual Coupling and Miscalibration Effects

Beamforming techniques utilized either at the transmitter or the receiver terminals have achieved superior quality-of-service performances from both the multi-antenna wireless communications systems, communications intelligence and radar target detection perspectives. Despite the overwhelming advantages in ideal operating conditions, beamforming approaches have been shown to face substantial performance degradations due to unknown mutual coupling effects and miscalibrated array elements. As a promising solution, blind beamformers have been proposed as a class of receiver beamformers that do not require a reference signal to operate. In this paper, a novel gradient-based blind beamformer is introduced with the aim of mitigating the deteriorating effects of unknown mutual coupling or miscalibration effects. The proposed approach is shown to find the optimal weights in different antenna array configurations in the presence of several unknown imperfections (e.g., mutual coupling effects, miscalibration effects due to gain and phase variations, inaccurate antenna positions). By providing numerical results related to the proposed algorithm for different array configurations, and bench-marking with the other existing approaches, the proposed scheme has been shown to achieve superior performance in many aspects. Additionally, a measurement-based analysis has been included with validation purposes.Comment: Presented in EuCAP 2023, Copyright IEE
