    Objective: Pollen calendars, which exposes by determinig airborne pollen, help the allergologists and the people that sensitive to allergenic pollen. The goal of this study to identify the airborne pollen grains to establish the pollen calendar of Gemlik (Bursa) in the year 2008.Materials and Methods: Airborne pollen grains in Gemlik (Bursa) were collected between 1st January and 31st December 2008 by using Durham sampler. Weekly pollen grains per cm2 were calculated.Results: During the period 6957 pollen grains/cm(2) belonging to 43 taxa (excluding unidentified pollen grains) were recorded. Eleven plant taxa take a place, which encountered up to 1% of the total and it can be reported that pollen season durations and total percentages for the dominaing pollen grains in Gemlik were; 5-32nd week for Pinus spp. (22.14%), 19-37th week for Olea europaea L. (18.19%), 9-43rd week for Gramineae (10.62%), 1224th week for Platanus spp. (10.58%), 4-27th week for Cupressaceae/Taxaceae (10.19%), 13-23rd week for Fagus spp. (6.09%), 9-21st week for Quercus spp. (5.33%), 5-19th week for Fraxinus spp. (2.41%), 423rd week for Betula spp. (1.81%), 27-44th week for Xanthium spp. (1.53%) and 14-22nd week for Jug-lans spp. (1.35%). 40.46% of total pollen grains were recorded during the month of april with a prevalence of arboreal pollen grains.Conclusion: This preliminary study performed to determine pollen calendar for Gemlik region (Bursa) may be useful for allergologists to establish an exact diagnosis of the people that has pollen allergy.

    Alternative and natural therapies are needed for malignant melanoma (MM), the most deadly skin cancer type due to chemotherapy's limited effect. In the present study, we evaluated the anticancer potentials of Inula viscosa methanol and water extracts (IVM and IVW) on MM cells, A2058 and MeWo, and normal fibroblasts. After the chromatographic and antioxidant activity analysis, their antiproliferative effects were determined with the increasing doses for 24-72 h. IVM induced more cell death in a dose and time-dependent manner in MM cells compared to IVW. This effect was probably due to the higher amount of phenolics in it. IVM significantly induced more apoptotic death in MM cells than fibroblasts (p < 0.01), which was also supported morphologically. IVM also caused cell cycle arrest at G0/G1 and G2/M phases in A2058 and MeWo, respectively, and suppressed the migration ability of MM cells (p < 0.01). Additionally, IVM was found to have significant potential in regulating MM-related miRNAs, upregulating miR-579 and miR-524, and downregulating miR-191 and miR-193, in MM cells (p < 0.05, p < 0.01). As a result, the anticancer effect of IVM via regulating miRNAs' expression has been demonstrated for the first time. Thus, IVM, with these potentials, may be a promising candidate for MM treatment.

    The stem-like cells of Glioblastoma multiforme (GBM) tumors (GSCs) are one of the important determinants of recurrence and drug resistance. The aims of the current study were to evaluate the anticancer effect of Olea europaea leaf extract (OLE) on GBM cell lines, the association between OLE and TMZ responses, and the effect of OLE and the OLE-TMZ combination in GSCs and to clarify the molecular mechanism of this effect on the expression of miRNAs related to cell death. The anti-proliferative activity of OLE and the effect of the OLE-TMZ combination were tested in the T98G, U-138MG and U-87MG GBM cell lines using WST-1 assay. The mechanism of cell death was analyzed with Annexin V/FITC and TUNEL assays. The effects of OLE on the expression levels of miR-181b, miR-153, miR-145 and miR-137 and potential mRNA targets were analyzed in GSCs using RT-qPCR. OLE exhibited anti-proliferative effects via apoptosis and necrosis in the GBM cell lines. In addition, OLE significantly induced the expression of miR-153, miR-145, and miR-137 and decreased the expression of the target genes of these miRNAs in GSCs (p < 0.05). OLE causes cell death in GBM cells with different TMZ responses, and this effect is synergistically increased when the cells are treated with a combination of OLE and TMZ. This is the first study to indicate that OLE may interfere with the pluripotency of GSCs by modulating miRNA expression. Further studies are required, but we suggest that OLE may have a potential for advanced therapeutic cancer drug studies in GBM.

    One of the most important allergens causing allergic diseases of the respiratory system is airborne tree, grass and weed pollen grains. Oleaceae family members are very important in tree pollen grains. In this study, airborne pollen studies were carried out in Turkey, and the monthly changes in Olea and Fraxinus pollens rates for 55 regions were evaluated. In the studies carried out, the highest Fraxinus pollen grains were recorded in spring, and Olea pollen grains were recorded in late spring and early summer. According to atmospheric pollen studies, although Fraxinus pollen grains were found in more regions than Olea, more Olea pollen grains were recorded than of Fraxinus.
