The effects of different nitrogen doses on yield, quality and leaf nitrogen content of some early grape cultivars (V. vinifera L.) grown in greenhouse

Nitrogen deficiency is a worldwide problem, causing restrictions in productivity of many horticultural produces. Particularly, the issue is compounded when the greenhouse production is employed. Therefore, reliable knowledge on proper application of nitrogen ensures not only satisfactory yield but also balanced vegetative and reproductive growth in plants. This study was thus conducted to investigate the effects of different nitrogen doses (10, 20 and 30 kg N da-1) on some quality properties with petiole nitrogen content of grape cultivars ‘Early Cardinal’ (EC), ‘Yalova Incisi’ (YI) and ‘Ergin Cekirdeksizi’ (ER) grown in plastic greenhouse for two years. Overall results indicated that cluster weight, cluster length and yield values increased depending on the nitrogen doses. On the other hand, increasing nitrogen applications generally resulted in higher petiole nitrogen content. The highest petiole nitrogen values were obtained from the treatment of 30 kg N da-1 for two phenologycal periods (1.29 and 1.59% for full bloom and veraison, respectively). Considering the general investigations, 20 kg N da-1 application could be recommended in terms of nitrogen supply under such conditions.Key words: Grapevine, nitrogen fertilizing, yield, petiole analysis

EML4-ALK variants: biological and molecular properties, and the implications for patients

Since the discovery of the fusion between EML4 (echinoderm microtubule associated protein-like 4) and ALK (anaplastic lymphoma kinase), EML4-ALK, in lung adenocarcinomas in 2007, and the subsequent identification of at least 15 different variants in lung cancers, there has been a revolution in molecular-targeted therapy that has transformed the outlook for these patients. Our recent focus has been on understanding how and why the expression of particular variants can affect biological and molecular properties of cancer cells, as well as identifying the key signalling pathways triggered, as a result. In the clinical setting, this understanding led to the discovery that the type of variant influences the response of patients to ALK therapy. Here, we discuss what we know so far about the EML4-ALK variants in molecular signalling pathways and what questions remain to be answered. In the longer term, this analysis may uncover ways to specifically treat patients for a better outcome

Some notes on commutators of the fractional maximal and Riesz potential operators on Orlicz spaces

The main focus of this paper is commutators and maximal commutators on Orlicz spaces for fractional maximal functions and Riesz potential. The main advance in comparison with the existing results is that we manage to obtain conditions for the boundedness in less restrictive terms

Fractional maximal function and its commutators on Orlicz spaces

In this paper, we find necessary and sufficient conditions for the boundedness of fractional maximal operator $M_{\alpha}$ on Orlicz spaces. As an application of this results we consider the boundedness of fractional maximal commutator $M_{b,\alpha}$ and nonlinear commutator of fractional maximal operator $[b,M_{\alpha}]$ on Orlicz spaces, when $b$ belongs to the Lipschitz space, by which some new characterizations of the Lipschitz spaces are given.Comment: 15 pages, Anal.
