    Composition of essential oil of Cuminum cyminum L. according to harvesting times
    (2007) Kan Y.; Kartal M.; Özek T.; Aslan S.; Başer K.H.C.
    The cumin (Cuminum cyminum L.) is an annual plant of Apiaceae. It is generally used as a food additive for increasing the flavour of different food preparations. The fruits (often called seed )are rich in essential oil with the main constituents at different harvesting time being cumin aldehyde (19.9-23.6%), p-mentha-1,3-dien-7-al (11.4-17.5 %) and p-mentha-1,4-dien-7-al (13.9-16.9). The results of GC and GC/MS analysis showed that the fruits should be harvested at the ripe stage for ideal volatile oil yield and composition. The effect of different harvesting times on the yield and ratio of main components of the essential oil are evaluated.

    Composition of essential oil of fennel fruits cultivated at different conditions [Farkli koşullarda yeti?sti?ri?len rezene meyveleri?ni?n uçucu ya? bi?lesenleri?]
    (2006) Kan Y.; Kartal M.; Aslan S.; Yildirim N.
    The fennel (Foenicilum vulgare Miller subsp. vulgare var. dulce (Miller) is an annual plant of Apiaceae. It is widely used as flavouring agent in foodstuffs. It also is used commonly a as stimulation of gastrointestinal in folk medicine. The fruits are rich in essential oil and the main constituents at different cultivated conditions were found to be trans-anethole 60.6-87.0 %, anisaldehyde 6.1-21.3 %, estragole 3.2-11.7%, ?-fenchone 0.7-3.2 %, limonene 0.3-2.5 %, carvone 0.3-1.0 % and cis-anetol 0.2-0.9 %. The results of GC and GC/MS analysis showed that the fruits should be cultivated at nitrogenous conditions for volatile oil yield and composition. The effect of different fertilizers and doses on the yield and ratio of main components of the volatile oil are evaluated.

    Expression of epidermal growth factor (egf) and heparin-binding egf (hb-egf) mrna in mare endometrium
    (Veteriner Fakultesi Dergisi, 2012) Atli M.O.; Güzeloğlu A.; Kurar E.; Kayiş S.A.; Aslan S.; Semacan A.; Çelik S.
    EGF and HB-EGF play crucial roles in embryonic development and peri-implantation. In this study, aim was to characterize expression profiles of EGF and HB-EGF in mare endometrium during estrous cycle and early pregnancy. Endometrium biopsies were obtained from mares on day of ovulation (d0), late diestrus (LD) and after luteolysis (AL) in the estrus phase. In pregnant groups, biopsies were taken on days 14 (P14), 18 (P18), 22 (P22) and 60 (P60). Relative expression levels of genes were quantified using real-time RT-PCR. A mixed model was fitted on the normalized data and Least Significant Difference (LSD) test was employed to determine significantly different group(s). EGF mRNA expression was up-regulated at LD compared to d0 while HB-EGF expression was not changed throughout the cycle. EGF expression was also increased during early pregnancy with the highest expression level observed on P60. Similarly, HB-EGF mRNA level was increased on P60. Pregnancy induced EGF expression on P14 and P18 compared to LD and AL whereas expression of HB-EGF was only significantly higher on P18 than that of AL. These results indicate that EGF expression is up-regulated during the cycle at late diestrus when P4 is high and is increased by pregnancy. HB-EGF expression is induced later in the pregnancy. In conclusion, EGF and HB-EGF appear to involve in the events that happen in the mare endometrium during peri-implantation period.
