Eggshell calcification after intrathyroidal hemorrhage of retrosternal thyroid

We report a rare event of old hemorrhage into a thyroid causing respiratory distress. A 67-year-old man with chronic cough and recent dysphagia was found to have a retrosternal mass extending into the visceral mediastinum on chest roentgenogram. A computed tomographic (CT) scan confirmed eggshell callcification, which was 53 × 53 × 80 mm in size a retrosternal thyroid mass and revealed significant tracheal deviation to the right due to an extensive mass surrounded by a calcificated capsule in the left lobe of the thyroid gland with extension to the upper mediastinum. He successfully underwent left lobectomy of the thyroid gland with sternotomy. The pathological examination revealed intrathyroidal hemorrhage of the thyroid gland with massive intracystic old bleeding

Association Between Vitamin D Receptor Polymorphism and Familial Mediterranean Fever Disease in Turkish Children

Familial Mediterranean fever (FMF) is an autosomal recessive, inherited autoinflammatory disease characterized by recurrent, self-limited attacks of fever, and inflammation of serosal surfaces. The aim of our study was to determine a possible relationship between Vitamin D receptor (VDR) gene polymorphisms and the risk of children with FMF. We investigated VDR FokI (rs10735810), TaqI (rs731236), BsmI (rs1544410), and ApaI (rs7975232) polymorphisms in 50 children with FMF and 150 age-matched healthy control subjects. This study was performed by polymerase chain reaction-based restriction fragment length polymorphism. There was no significant difference between patients and controls for VDR FokI, TaqI, BsmI, and ApaI genotypes and alleles (p > 0.05). Results need to be supported by further investigations that define haplotype patterns for VDR gene polymorphisms in a larger group and different ethnic groups of FMF patients

Darden Restaurants, Inc. Is the turnaround happening?

This case study discusses the recent strategic turnaround of the largest casual U.S. restaurant corporation, Darden Restaurants Inc. (NYSE:DRI). It explores the various reasons for a sharp decline in Darden\u27s growth and disappointing operational performance in recent years. It also examines the strategic measures taken by newly formed executive board for the company\u27s operational rebound. This case further details the implementation of the revival plan by performing a critical longitudinal financial assessment. Lastly, the company\u27s turnaround efforts and future prospects to re-energize its brands in the market are discussed

Career decision-making self-efficacy of young adolescent students in Turkey

Multiple regression was used to investigate whether the perfectionism perceptions, automatic thoughts, and the grade point average (GPA) of young adolescent students predict their career decision-making self-efficacy levels. The final sample included 383 students in their eighth year of school. Results indicate that positive perfectionism, automatic thoughts, and GPA predict students’ levels of career decision-making self-efficacy. Furthermore, exploratory analyses indicated that female students had higher levels of career decision-making self-efficacy than did male students, as did students whose mothers were graduates of two and four-year postsecondary educational institutions versus high school. Practical recommendations and research suggestions are proposed. © 2018, © 2018 International School Psychology Association

Soil organic matter mineralization under different temperatures and moisture conditions in Kizildag plateau, Turkey

Drought by climate change in East Mediterranean Region will change soil temperature and moisture that lead to alter the cycling of biological elements like carbon and nitrogen. However, there are few studies that show how sensitivity of soil organic matter mineralization to temperature and/or moisture can be modified by changes in these parameters. In order to study how these changes in temperature and moisture affect soil carbon and nitrogen mineralization, a laboratory experiment was carried out in two depths (0-5 and 5-15 cm) of soils of Onobrychis beata and Trifolium speciosum being common annual plants in Turkey that was taken from Kizildag Plataeu (Adana city). Some soil physical and chemical properties and as well as rate of carbon and nitrogen mineralizations were determined for both depths of soils. These soils were incubated for 42 days under different field capacities (FC 60, 80 and 100%) and temperatures (24, 28 and 32°C). Cumulative carbon mineralization (Cm), potential mineralizable carbon (C0) and rate of carbon mineralization of all soils were increased with rising temperatures. Rate of carbon mineralization in O. beata soil were lower than T. speciosum soil. NH4-N and NO3-N contents at 42nd day were higher than initial levels of soils and also increased with temperatures and field capacities. In summary, sensitivity of soil organic matter mineralization to temperature was higher at 32°C in upper layer and lower at 24°C in deeper layer of both soils

How titanium dioxide and zinc oxide nanoparticles do affect soil microorganism activity?

The increasing use of nanoparticles (NPs) in recent years has posed a potential threat to the natural ecosystem. The aim of this study was to determine the C and N mineralizations of different textured (clay and sandy) soils at increasing doses of (25, 50 and 100 mg kg -1 ) TiO 2 NPs and ZnO NPs that are biological synthesized from Peganum harmala L. plant extract, and to reveal their potential effects on the soil ecosystem. The carbon (C) and nitrogen (N) mineralizations were respectively determined by the CO 2 respiration method and the Parnas-Wagner method under the controlled laboratory conditions for 42 days (28 °C, 80% of field capacity). The highest carbon mineralization among all applications was in clay soils mixed with 100 mg kg -1 TiO 2 NPs. In clay soils treated with ZnO NPs, the treatment of 50 mg kg -1 ZnO NPs increased microorganism activity (P < 0.001). Carbon mineralization rates were found to be higher in sandy soils compared to clay soils (P < 0.05). It was observed that these rates were higher in the TiO 2 NPs treated soils compared to the ZnO NPs treated soils. The nitrogen mineralization ratios were found to be higher in clay soils compared to sandy soils. All of these results indicate that the microorganisms affected from both the presence of TiO 2 NPs and ZnO NPs and differences of texture in these two soils. © 2019 Elsevier Masson SA

Carbon and nitrogen mineralization in Arachis hypogaea L. soil treated with domestic and industrial activated sludges

Organic wastes, such as activated sludge, obtained from solid waste purification plants of city municipalities are used for organic carbon and nutrient sources to the soil. Moreover, the origin, amount and nutrient contents of activated sludge are important for soil microorganisms. Activated sludge collected from domestic and industrial waste plants of Adana, Osmaniye and Gaziantep were added to peanut soil at three doses of sludge (2, 3 and 4 g/100 g oven dried soil) to compare carbon and nitrogen mineralization. Experiments were run at 28°C over 45 days. Carbon (C) and nitrogen (N) mineralization was measured in vitro. The highest microbial activity and carbon mineralization ratio was observed in soil mixed with 4 g industrial activated sludge of Gaziantep. Increasing doses of industrial activated sludges of Osmaniye and Gaziantep decreased nitrogen mineralization. These results might be explained by the origin and composition of industrial activated sludge of especially Gaziantep city and organic carbon and nitrogen in it. © by PSP
