Homocysteine May Involve in the Pathogenesis of Behcet's Disease by Inducing Inflammation

Objective. Our aim was to evaluate the significance of homocysteine (Hcy) in Behcet's disease (BD) and the association of elevated Hcy levels associated with the indices of inflammation in BD. Methods. Untreated 70 patients with BD and 33 healthy individuals were included into the study. Hcy, tumor necrosis alpha (TNF-α), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) were evaluated with respect to activity and specific individual clinical manifestations of the disease. Results. Hcy levels were found significantly elevated in active BD when compared to inactive BD and healthy controls. Hcy levels were found to have high correlation with the number of active clinical manifestations increased. A significant positive correlation was found between serum Hcy and TNF-α levels, CRP, and ESR. Hcy was found to be the best predictor of TNF-α among other parameters. Conclusion. Hcy may involve in the pathogenesis of BD by inducing inflammation

Estimation of using Modifications of Ranked Set Sampling for Weibull Distribution

In statistical literature, estimation of R=P(X<Y) is a commonly-investigated problem, and consequently, there have been considerable number of studies dealing with its estimation of it under simple random sampling (SRS). However, in recent years, the ranked set sampling (RSS) method have been widely-used in the estimation of R. In this study, we consider the estimation of R when the distribution of the both stress and strength are Weibull under the modification of RSS, which are extreme ranked set sampling (ERSS), median ranked set sampling (MRSS) and percentile ranked set sampling (PRSS). We obtain the estimators of R using the maximum likelihood (ML) and the modified maximum likelihood (MML) methodologies under these modifications. Then the performances of proposed estimators are compared with the corresponding ML and MML estimators of R using SRS via a Monte-Carlo simulation study

Wastewater use in irrigation - Ankara case study

Demand for water is increasing in the world parallel to increase in population and industrialization. Thus, efforts are geared toward finding ways of utilizing the previously unused sources of water and/or recycling wastewater. Sustainability and effective use are the vital issues for these new sources of water as well as the existing ones. This study examined the possible use of treated wastewater of Ankara Wastewater Treatment Plant over agricultural areas for irrigation purposes. It focused on effective ways in which cleaned water can be used for agricultural purposes and on the economic advantages of such use. Implications for sustainable water management were also discussed

Large-cell lung cancer originating from tracheal bronchus - A rare case

WOS: 000372911100025PubMed ID: 27122281Tracheal bronchus is a rarely seen congenital anomaly generally originating from the right lateral wall of the trachea and approximately 2 cm above the carina. It was firstly defined by Sandifort in 1785 and its frequency of incidence in normal population changes between 0.1% and 2%. There are two types called ''Supernumerary'' and ''Displaced''. It is a rarely seen kind of tracheal anomaly although fairly well defined. The cases accompanied by lung cancer are seen more rarely. Nine cases of this association were reported in literature and tracheal bronchus-lung cancer association whose pathological result is undifferentiated large-cell carcinoma has not been stated so far. We present a 75 years old male patient as possibly the first case having tracheal bronchus and large-cell carcinoma association in literature
