Effects of different greenhouse media and hormones on Propagation by Cutting of Weigela floribunda and Spiraea x vanhouttei

In the present study, the effects on rooting success of different greenhouse media (Greenhouse-1 media with air temperature at 20±2°C, rooting table temperature at 20±2°C and humidity at 70%±2, Greenhouse-2 media with air temperature at 20±2°C, rooting table temperature at 25±2°C and humidity at 70%±2) and different doses (1000 and 5000 ppm) of hormones (IBA and NAA) on propagation by cutting of Weigela floribunda (Sieb. and Zucc.) K. Koch and Spiraea x vanhouttei (Briot) Zabel which are widely used in landscape studies were investigated. First callus and root formation, root length (RL), the number of root (RN) and rooting percentage (RP) were determined in the scope of this study. For both species, the highest rooting success was determined as 100%. For Weigela floribunda, the highest rooting percentage was determined in Control, IBA 5000 ppm, NAA 1000 ppm and NAA 5000 ppm treatments in Greenhouse-1 media, and also in NAA 1000 ppm and NAA 5000 ppm treatments in Greenhouse-2 media. For Spiraea x vanhouttei, the highest rooting percentage was determined in Control and IBA 5000 ppm treatments in Greenhouse-1 media. In terms of root length and the number of roots, the highest results were obtained in Greenhouse-1 media for Weigela floribunda, in Greenhouse-2 media for Spiraea x vanhouttei. Also, the effects of greenhouse media and hormones on other measured characteristics were statistically evaluated

Thyroid volumes and serum VEGF levels in dyslipidemic patients

Background/aim Defective vascularization may be important in thyroid nodular disease. In this study, we aimed to investigate serum vascular endothelial growth factor (VEGF) levels in dyslipidemic patients with thyroid nodules, as well as the effects of statin therapy. Materials and methods The study included 37 dyslipidemic patients with thyroid nodules and 32 dyslipidemic patients without thyroid nodules. Anthropometry, serum VEGF levels, biochemical parameters, thyroid-stimulating hormone (TSH), free triiodothyronine (fT3) and free thyroxine (fT4) levels, and thyroid sonography were determined before and after 6 months of statin therapy. Results Patients with and without thyroid nodules had similar metabolic parameters. Serum VEGF levels did not differ between the groups. In patients with nodules, VEGF levels remained unchanged (P = 0.931) after statin therapy. However, serum VEGF levels were lowered by statin treatment in patients without nodules (P = 0.030). Statin therapy resulted in a decrease in the dominant thyroid nodule volume. The changes in thyroid volume and dominant thyroid nodule volume were not correlated with changes in VEGF, body mass index, total cholesterol, low-density lipoprotein cholesterol, or homeostatic model assessment of insulin resistance (HOMA-IR). Conclusion Although statin treatment decreases serum VEGF levels in dyslipidemic patients without thyroid nodules, it has no lowering effect on serum VEGF levels in patients with thyroid nodules. The decrease in thyroid nodule volume with statin treatment was associated with neither metabolic parameters nor serum VEGF levels.PubMedWoSScopu
