Farklı İBA konsantrasyonları ve bekletme sürelerinde bozkır otu çeliklerinin çoğaltılması

Forage kochia, a subshrub forage plant, grows naturally in the pastures of dry areas in Turkey. Their seeds grow slowly in nature, and being short duration of seed viability could be caused by limitations on the cultivation of forage kochia in Turkey. Forage kochia seedlings can be produced serially quickly with cutting propagation as vegetation propagation method. Therefore, forage kochia cuttings were exposed to 12 different IBA concentrations (250, 500, 1000, 1500, 2000, 2500, 3000, 4000, 5000, 6000, 10000, and 15000 mg kg-1 ) at four holding times (5, 30, 180, and 900 s) in this research carried out Completely Randomized Design in the greenhouse. We investigated the percentage of rooting, the number of the root, shoot and root length, shoot and root weight, dry root weight, and leave yellowing of these cutting. The best developments in the percentage of rooting (100%), number of roots (> 7), shoot length (> 20 cm), root length (>10 cm), root weight (>0.60 g), dry root weight (>0.1 g) and leave yellowing (score >1.60) were obtained from 500 mg kg-1 IBA at 900 s, 5000 mg kg-1 IBA at 180 s, and 10000 mg kg-1 IBA at 5 s interactions. As a result, we advised 500 mg kg-1 IBA at 900 s, 5000 mg kg-1 IBA at 180 s and 10000 mg kg-1 IBA at 5 s for the quick and economically cutting propagation of forage kochia.Yarı çalı bir yem bitkisi olan bozkır otu, Türkiye’nin kurak alanlarındaki meralarda doğal olarak yetişmektedir. Bozkır otunun doğada tohum ile büyümesi çok yavaş ve tohum canlılığı süresinin kısa olması ülkemizde bozkır otu tarımında kısıtlamaya neden olmaktadır. Vejetatif çoğaltma yöntemi olarak çelikle çoğaltma ile bozkır otu fidesi daha kısa sürede seri bir şekilde üretilebilir. Bu sebeple, Tesadüf Parselleri Deneme Desenine göre serada yürütülen bu çalışmada 4 adet sürede (5, 30, 180 ve 900 s) ve 12 farklı IBA konsantrasyonlarına (250, 500, 1000, 1500, 2000, 2500, 3000, 4000, 5000, 6000, 10000 ve 15000 mg kg-1 ) bozkır otu çelikleri maruz bırakıldı. Bu çeliklerin köklenme yüzdesi, kök sayısı, fide ve kök uzunluğu, yaş fide ve kök ağırlığı, kuru kök ağırlığı ve yaprak sararması incelenmiştir. Çeliklerde köklenme yüzdesi (%100), kök sayısı (>7 adet), fide uzunluğu (>20 cm), kök uzunluğu (>10 cm), kök ağırlığı (>0.60 g), kuru kök ağırlığı (>0.1 g) ve yaprak sararması (Skor >1.60) açısından en iyi gelişim 900 saniyede 500 mg kg-1 IBA, 180 saniyede 5.000 mg kg-1 IBA ve 5 saniyede 10.000 mg kg-1 IBA konsantrasyonlarından elde edilmiştir. Sonuç olarak bozkır otunun ekonomik ve hızlı bir şekilde çelikle çoğaltılması için 900 saniyede 500 mg kg-1 IBA, 180 saniyede 5.000 mg kg-1 IBA ve 5 saniyede 10.000 mg kg-1 IBA konsantrasyonları önerilmektedir

The Determination of Botanical Properties of Forage Kochia Population Grown in Konya Conditions

Adverse soil and environmental factors cause a decrease in pasture yield in our country. Shrub species are given importance in breeding studies carried out in order to increase the yield in marginal pastures in the world. Forage kochia (Kochia prostrata), which is a naturally growing and semi-shrub in Turkey%252339%253Bs flora, shows tolerance to adverse soil and climatic conditions. This research was established in Konya in October 2017 according to the Randomized Complete Block Design with 4 replications. In the research, the morphological and yield values of the forage kochia populations collected from 5 different locations in Konya (i.e., Karapınar Kartal Kayaları, Bahri Dağdaş I.A.R.I, Campus Beltway-Selçuklu, Ardıçlı Rural- Selçuklu, and S.U.F.A. Forage Kochia Demonstration Garden) were examined during 2018-2019. We investigated the blooming time (Scoring), plant height (cm), canopy diameter (cm), number of branch, stem diameter (mm), shape of habitus (Scoring), leaf length (mm), leaf width (mm), color of anther and stigma (Scoring), fodder yield per plant (g) and hay yield per plant (g). In this study, the Campus Beltway- Selçuklu Population (3P) bloomed the earliest in this area between the end of August and early September (Score 5,36). Among the forage kochia populations showing semi-decumbent habitus (Score 7,05-7,63) the Karapınar Kartal Kayaları Population (1P) had the highest yield potential regarding plant height (i.e., 46,63 cm), canopy diameter (i.e., 50,50 cm), fodder yield per plant (i.e., 112 g), and hay yield per plant (i.e., 45,28 g). In line with the findings obtained in the study, while the Karapınar Kartal Kayaları Population (1P) and the Campus Beltway- Selçuklu Population (3P) stand out in terms of yield and yield components. These results show us that each population is a valuable gene resource in plant breeding for pasture improvement

Effects of excess vitamin B6 intake on cerebral cortex neurons in rat: an ultrastructural study

The aim of this study was to investigate whether excess of vitamin B6 leads to ultrastructural changes in cerebral cortex of forty-eight healthy albino rats which were included in the study. Saline solution was injected to to the control groups (CG-10, n=12 for 10 days; CG-15, n=12 for 15 days; CG-20, n=12 for 20 days). The three experimental groups (EG-10, n=12; EG-15, n=12; EG-20, n=12) were treated with 5 mg/kg vitamin B6 daily for 10 days (EG-10), 15 days (EG-15) and 20 days (EG-20). Brain tissues were prepared by glutaraldehyde-osmium tetroxide double fixation for ultrastructural analysis. No significant changes were observed in the control groups. The ultrastructural analysis revealed that the numbers of damaged mitochondria, lipofuscin granules and vacuoles were significantly higher in all the experimental groups than in the control groups (

Changes in Serum Natriuretic Peptide Levels after Percutaneous Closure of Small to Moderate Ventricular Septal Defects

Background. B-type natriuretic peptide has been shown to be a very sensitive and specific marker of heart failure. In this study, we aimed to investigate the effect of percutaneous closure of ventricular septal defects with Amplatzer septal occluders on brain natriuretic peptide levels. Methods. Between 2008 and 2011, 23 patients underwent successfully percutaneous ventricular septal defect closure in 4 cardiology centers. Brain natriuretic peptide levels were measured in nine patients (4 male, mean ages were 25.3 ± 14.3) who underwent percutaneous closure with Amplatzer occluders for membranous or muscular ventricular septal defects were enrolled in the study. Brain natriuretic peptide levels were measured one day before and one month after the closure. Patients were evaluated clinically and by echocardiography one month after the procedure. Results. Percutaneous closures of ventricular septal defects were successfully performed in all patients. There was not any significant adverse event in patients group during followup. Decrease in brain natriuretic peptide levels after closure were statistically significant (97.3 ± 78.6 versus 26.8 ± 15.6, P = 0.013). Conclusion. Brain Natriuretic Peptide levels are elevated in patients with ventricular septal defects as compared to controls. Percutaneous closure of Ventricular Septal Defect with Amplatzer occluders decreases the BNP levels

Naiv hepatit C enfeksiyonlu hastaların on-altı yıllık prognozu

Objectives: In this study, we aimed to evaluate the clinical course of treatment-naive patients infected with hepatitis C virus (HCV) who were followed up in various centers in Turkey. Materials and Methods: This was a retrospective study performed with the participation of 15 centers. Patients aged 18 years and older with HCV infection were included. Results: A total of 391 treatment-naive patients infected with HCV were included in this study. During the follow-up period, the final values of alanine aminotransferase, aspartate transaminase, and total protein were significantly decreased when compared to the initial values (p<0.001, p<0.001, and p=0.005, respectively). In the study group, 19.2% of the patients underwent liver biopsy and 4.1% underwent transient elastography (FibroScan). An increased histological activity index (HAI) score and fibrosis in the second biopsy were observed in one patient, only increased HAI in two patients and increased fibrosis in one patient, as shown on the FibroScan. In the 16 years of the study period, cirrhosis was radiologically detected in only one patient. Conclusion: Even if rapid progression is not observed, close monitoring of the clinical findings related to liver failure and fibrosis with invasive or non-invasive methods may be useful.Amaç: Bu çalışmada ülkemizin çeşitli merkezlerinde takip edilen naiv hepatit C virüs (HCV) ile enfekte hastaların klinik seyrini değerlendirmeyi amaçladık. Gereç ve Yöntemler: Bu çalışma retrospektif olarak 15 merkezin katılımıyla gerçekleştirilmiştir. Çalışmaya 18 yaş üstü, HCV enfeksiyonu olan hastalar dahil edilmiştir. Bulgular: Çalışmada 391 tedavi-naiv HCV enfeksiyonlu hasta yer almıştır. Hastaların takip süresinde son alanine aminotransferase, aspartate transaminase ve total protein değerleri ilk düzeyine göre önemli düzeyde azalmıştır (sırasıyla p<0,001, p<0,001, p=0,005). Çalışma grubunda hastaların %19,2’sine karaciğer biyopsisi, %4,1’ine elastografi (FibroScan) uygulanmıştır. Takip esnasında bir hastada ikinci biyopside histolojik aktivite indeksi (HAI) ve fibroziste artma, iki hastada sadece HAI’da artma, birinde FibroScan ile fibrozis değerinde artma olduğu gözlenmiştir. Bir hastada 16 yıl içinde radyolojik olarak siroz saptanmıştır. Sonuç: Hızlı progresyon gözlenmemekle birlikte hastaların izleminde karaciğer yetmezliği ile ilgili klinik bulguların ve invaziv veya noninvaziv yöntemlerle fibrozisin yakın takibi yararlı olabilir

Volumetric evaluation of fat in the renal sinus in normal subjects using stereological method on computed tomography images and its relationship with body composition

Background: The aim of the study was: to describe a simple, accurate and practical technique for estimating the volume of adipose tissue within the renal sinus (RS) using stereological method on computed tomography (CT) images; to establish a population database for volume of fat within the RS from 21 to 80 years of age; to investigate the effect of age, gender, body mass index (BMI) and abdominal diameters on RS fat volume in normal subjects. Materials and methods: We retrospectively reviewed abdominal CT examinations of 240 patients without renal pathology between the ages of 21 and 80 years. There were 6 groups of patients, with 40 patients for each decade. Results: RS fat volumes in the left and right kidney were 5.70 +/- 2.87 cm(3) and 4.15 +/- 2.39 cm(3), respectively, in males and 3.51 +/- 2.67 cm(3) and 2.49 +/- 2.16 cm(3), respectively, in females. RS fat volume and age were positively correlated for both kidneys (left: r = 0.46; right: r = 0.44; p < 0.001, both), though it appeared to decline after age 70. Conclusions: Quantitative data may allow clinicians to better estimate the age- related RS fat volume changes and help them in decision making

Partial root zone drying irrigation and different nitrogen levels affect on nitrogen recovery efficiency for drip irrigated sugar beet crop

This study was conducted to determine different nitrogen levels affect on nitrogen recovery efficiency, NRE, by use of drip irrigation under partial root zone drying irrigation and fertigation techniques for sugar beet plant. Research was performed in 2012 and 2013 at Konya - Çumra Plain of Turkey and Stine sugar beet cultivar was used. In study, application of 100% irrigation water requirement of plant, FI (Full Irrigation) and 50% application of FI by using fixed (FPRD50) and alternative partial root drying (APRD50) irrigation techniques, and application of 100% nitrogen requirement of sugar beet, FN (Full Nitrogen) with two deficit nitrogen treatments of 75% (DN75) and 50% (DN50) of FN levels were applied by drip irrigation. Different deficit nitrogen applications affect on crop nitrogen use was researched comparatively under different irrigation techniques and fertigation method. The results showed that among the irrigation treatments, differences in NRE from nitrogen fertilizer were found not significant. DN50 was found the highest NRE of crop from nitrogen fertilizer. The greatest performances combinations in NRE of crop from fertilizer nitrogen were, FIDN50 as 52.6%, APRD50DN50 as 48.5% and FPRD50DN50 as 41.0% interactions. Those results showed that nitrogen requirement of crop can be reduced for drip irrigated sugar beet farming
