A study on Reseda lutea L. distributed naturally in West Anatolia in Turkey

Morphology and seed germination of Reseda lutea L. (Resedaceae), which is distributed naturally in Turkey, were investigated. Germination trial was observed at 10, 15, 20, 25, 30, 35 and 40 °C. In laboratory conditions at 25 °C, 87% of the seeds of R. lutea germinated, while in soil conditions, the best germination rate was only 23%, achieved with seeds sowed at 10 mm depth. The results of germination under different light conditions showed that the germination rate at 25 °C in continuous darkness was 87%, 76% with 6 hours of light, 67% with 12 hours of light, 52% with 18 hours of light and 42% with continuous light. Measurements of samples collected from different localities showed that the length of the plant is inversely proportional to the altitude

A study of the soil-plant interactions of Pistacia lentiscus L. distributed in the western Anatolian part of Turkey

This study was undertaken with the aim of illuminating the soil-plant interactions of Pistacia lentiscus L., which is a Mediterranean sclerophylleous coastal zone plant in the Western Anatolian part of Turkey. The soil analysis data showed that this plant grows on different kinds of soils such as sandy-clayey-loam, clayey-loam, sandy-loam and loamy texture. Soils are not saline, with pH moderately and slightly alkaline. This species prefers soils with low phosphorus and potassium contents, but with different calcium carbonate and nitrogen contents. Three negative linear correlations were observed between plant calcium and soil pH, plant nitrogen and soil calcium carbonate, plant potassium and soil calcium carbonate

Determination of trace elements in the plants of Mt. Bozdag, Izmir, Turkey

The aim of this study was to determine the current level of atmospheric heavy metal content on the Bozdag Mountain of the Aegean Region, Turkey. Twenty nine different plants were selected to study their potential as biomonitors of trace elements such as Ni, Zn, Fe, Pb, Mn and Cd (μg g-1, dry weight). The samples were collected from two different altitudes of Mt. Bozdag. The concentrations of trace elements were determined by atomic absorption spectrometry. The mean concentrations determined at 1000 m altitude ranged from 0.025 to 1.609, 0.232 to 0.731, 0.578 to 5.983, 0.287 to 0.565 and 0.176 to 2.659 (μg g-1, dry weight), for Ni, Zn, Fe, Pb and Mn, respectively. At the altitude of 1600 m, the values ranged from 0.023 to 0.939, 0.258 to 1.254, 0.839 to 5.176, 0.301 to 1.341 and 0.405 to 3.351 (μg g-1, dry weight) for Ni, Zn, Fe, Pb and Mn, respectively. No Cd was detected at either altitude. Statistical significance was determined by the independent sample t-test and comparisons were made in order to determine if there were any differences between the averages of herbaceous and woody plants.

Studija o biljkama uz rub cesta (Zapadna Anatolija, Turska)

In this study, roadside plants distributed throughout the link roads of all the cities in West Anatolia in Turkey were investigated. The length of the selected 17 roads is around 2700 km. The total number of samples collected from the study area is 271 taxa belonging to 57 families. Among them, Asteraceae, Fabaceae, Poaceae are the families that have the largest number of taxa, and Bromus L., Rumex L. and Silene L. are the genera that have the largest number of taxa. The most frequently found taxon throughout the selected roads is Valerianella coronata (L.) DC. and therophytes are the most frequently found life form.Istraživane su biljke uz rub svih cesta koje povezuju gradove u Zapadnoj Anatoliji u Turskoj. Duljina 17 izabranih cesta je iznosila oko 2700 km. Prikupljeni uzorci pripadali su 271 svojti, odnosno 57 biljnih porodica. Među njima su najzastupljenije bile porodice Asteraceae, Fabaceae i Poaceae, a među rodovima to su bili Bromus L., Rumex L. i Silene L. Najčešće nađena svojta uz istraživane ceste bila je Valerianella coronata (L.) DC., a najčešći biljni oblik su bili terofiti

Synchronous Detection of Hairy Cell Leukemia and HIV-Negative Kaposi's Sarcoma of the Lymph Node: A Diagnostic Challenge and a Rare Coincidence

Hairy cell leukemia (HCL) is an uncommon chronic lymphoproliferative disorder and accounts for around 2% of all forms of leukemias. The association of HCL with other neoplasms, mainly non-Hodgkin's lymphomas, is well known. However, the simultaneous diagnosis of HCL and Kaposi's sarcoma is rare, with only few cases of such an association having been reported. We describe a 42-year-old male patient with a well characterized HCL and in whom HIV-negative Kaposi's sarcoma of the lymph node was detected

Minimal residual disease (MRD) detection with translocations and T-cell receptor and immunoglobulin gene rearrangements in adult acute lymphoblastic leukemia patients: a pilot study

Objective: Monitoring minimal residual disease has become increasingly important in clinical practice of ALL management. Break-point fusion regions of leukaemia related chromosomal aberrations and rearranged immunoglobulin (Ig) and T cell-receptor (TCR) genes are used as leukaemia specific markers in genetic studies of MRD.Material and Methods: A total of 31 consecutive patients with newly diagnosed ALL were screened for eligibility criteria. Of those 26 were included in the study. One patient with partial response following induction therapy and four patients who were lost to follow-up after induction were excluded from the study; thus 21 patients were evaluated for MRD by using polymerase chain reaction (PCR), heteroduplex analysis, sequencing and quantitative real time PCR techniques. Results: Chromosomal aberrations were detected in 5 (24%) of the patients and were used for MRD monitoring. Three patients had t(9;22) translocation, the other 2 had t(4;11) and t(1;19). MRD-based risk stratification of the16 patients analysed for Ig/TCR rearrangements revealed 3 low-risk, 11 intermediate-risk and 2 high-risk patients.Conclusion: MRD monitoring is progressively getting to be a more important predictive factor in adult ALL patients. As reported by others confirmed by our limited data there is a good correlation between MRD status and clinical outcome in patients receiving chemotherapy. The pilot-study presented here is the first that systematically and consecutively performs a molecular MRD monitoring of ALL patients in Turkey
