Synergistic effects of methyl-β-cyclodextrin and coronatine on biomass accumulation and taxane secretion in Corylus avellana L. cell suspension cultures

Doğan, Ahmet

Taxanes are effective, natural-derived medicines widely utilized against various cancer types. Hazelnut (Corylus avellana L.) cell suspension culture systems offer a promising alternative platform for taxane production. The intracellular yields of taxanes in hazelnut cells can be elevated through elicitors such as coronatine. However, coronatine exhibits toxic effects on cell viability. Recently, methyl-β-cyclodextrins have been used to facilitate the secretion of taxanes into the extracellular medium, thereby preserving culture biomass. Herein, this study investigated for the first time the effects of 1 µM coronatine, alone or in combination with 50 mM methyl-β- cyclodextrin, on biomass accumulation and taxane production in cell suspension cultures of the Turkish hazelnut Kalınkara cultiv...

ABD Enerji ve Çevre Politikasında Trump Etkisi

Telli, Azime

Dünyanın en büyük enerji üreticisi ve tüketicilerinden biri olan ABD’nin enerji ve çevre politikası uluslararası sistemi önemli derecede etkilemektedir. ABD aynı zamanda en fazla karbon emisyonu üreten ülkeler listesinde Çin’den sonra ikinci sırada yer almakta olup küresel ısınmayla mücadele konusunda izleyeceği politikalar 2050 yılında sıfır emisyon hedefine ulaşılması açısından da kritik öneme sahiptir. Küresel ısınmayla mücadele ve enerji dönüşümünde uluslararası çabaların bir parçası olmakta genel olarak tutuk hareket eden ABD ucuz enerjiye dayalı ekonomik büyüme politikasını uzun yıllar sürdürmüştür. Bununla birlikte Demokrat Obama’nın başkanlığı döneminde Çin ile bu alanda uzlaşı sağlayarak Paris Şartı’na taraf olan ABD, enerji dönüşümü ve çevrenin korunması konusunda önemli a...

Avrupa’nın Enerji Arz Güvenliğinde Yeni Bağımlılık Sorunsalı: LNG’nin Yükselişi

Telli, Azime

Avrupa’nın enerjide dışa bağımlılığı hem 20. yüzyıl hem de 21. yüzyılda jeopolitik krizlerle sınanmıştır. Bir yandan kaynak çeşitlendirme bir yandan da enerji dönüşümü politikaları izleyen Avrupa ülkelerinin enerji arz güvenlikleri açısından Ukrayna Savaşı bir mihenk noktası olmuştur. Rusya’nın Ukrayna işgali öncesinde taraflar arasında mevcut bulunan enerjide karşılıklı bağımlılık durumu ciddi derecede sarsılmıştır. Rusya’nın enerji silahını kullanma girişimine AB öncülüğünde gösterilen sert tepkinin en büyük destekçisi ABD olmuştur. AB’nin Rus enerji kaynaklarına aşırı bağımlı olmasını tehdit olarak gören ABD, Ukrayna Savaşı’nın başlamasının ardından Avrupa pazarındaki en büyük LNG tedarikçisi konumuna gelmiştir. Avrupa ülkelerinin Rus boru gazı yerine LNG’ye yönelmesiyle başlayan b...

Özçimen Ahmet Ata | Ünal Selma | Yılmaz Melis | Aksu, Seçkin | Karahan Feryal

This study’s objective was to assess the relationship between serum cytokine levels and the occurrence of pulp necrosis (PN) and apical periodontitis (AP) in adolescents with Sickle Cell Disease (SCD). A total of 52 adolescents, including 29 individuals diagnosed with SCD, participated in the study. Serum cytokine levels including IL-1, IL-2, IL-4, IL-6, IL-1β, IL-8, IL-10, IL-17, and TNF-α were analyzed. Radiological and intraoral dental examinations were conducted on the same day. Electric pulp testing and cold tests were conducted on all intact crowned teeth to assess the presence of PN. Periapical index scores were derived from panoramic and periapical radiographs to identify teeth exhibiting AP. Statistical analyses were carried out using Student’s t-test, Chi-square test, Spea...

AB’nin Enerji Diplomasisinde Hazar Havzası Kaynaklarının Rolü

Telli, Azime

Avrupa Birliği’nin 21. yüzyıl enerji arz güvenliğinde dışa bağımlılık oranı en önemli sorun olarak karşımıza çıkmaktadır. AB ülkelerinin taleplerinin artmasından öte enerji arzlarının düşmesine bağlı olarak ortaya çıkan bu durum kaynak çeşitlendirme arayışına neden olmuştur. AB’nin Rus doğalgazına aşırı bağımlılığın yarattığı tehdide karşı alternatif rotalardan biri de Hazar Havzası’dır. AB’nin Hazar’ın rezervlerine Rusya’yı by-pass ederek ulaşma çabaları 20. yüzyılın sonuna kadar dayanmaktadır. AB enerji diplomasisinde öne çıkan bölgelerden biri olan Hazar doğal gazının Avrupa pazarına ulaştırılmasını hedefleyen boru hattı projeleri arasında ciddi bir rekabet yaşanmıştır. Rusya’nın Avrupa pazarındaki payını korumaya yönelik izlediği enerji diplomasisi gündeme Trans-Hazar ve NABUC...
