    Paratiroit Nakli İmmünolojisi
    (2019-04-01T00:00:00Z) Ayşan, Mustafa Erhan; Göncü, Beyza Servet; Yücesan, Emrah; GÖNCÜ, BEYZA SERVET; YÜCESAN, EMRAH
    Paratiroit nakli, kalıcı hipoparatiroidinin tek tedavi seçeneğidir. Diğer organ nakillerinde olduğu gibi greft fonksiyonunun artırılması için alıcı-verici uyumu paratiroit nakli için de çok önemlidir. Paratiroit nakli (bazı özel vakalar dışında) doğası gereği immünsupresyonsuz olarak gerçekleştirilmek zorunda olduğu için başarılı nakiller yapmak oldukça güçtür. Bu güçlüğü aşabilmek için elimizde güvenilir parametreler olmalıdır. İlk paratiroit naklinin yapılmasından günümüze kadar geçen yaklaşık 100 yıl içinde ne yazık ki A, B, 0 uyumu dışında üzerinde konsensus sağlanan bir kriter yoktur. Literatürde bu konudaki bilgi miktarı yetersiz olduğu gibi üstelik var olan bilgilerin doğruluğu da şüphelidir. Konu üzerinde daha fazla çalışma yapılmalıdır. Bu gerçekleşene kadar paratiroitte immünsüpresyon yapılmaksızın yüksek başarı oranıyla ve uzun greft fonksiyonu gösteren allo-nakiller yapmak zor görünmektedir.

    Achieving the balance: Biphasic effects of genistein on PC-3 cells
    (2019-08-01T00:00:00Z) Goncu, BEYZA; Yildiz, Mehmet Taha; Ozten-Kandas, Nur; GÖNCÜ, BEYZA SERVET; ÖZTEN KANDAŞ, NUR
    This study examined the response of PC-3 cells to physiological (0.5, 2.5, 5, 10 mu M) and pharmacological (50 mu M) concentrations of genistein which is a main bioactive compound in soy. Following 48 hr genistein treatment, cell-based assays and genome-wide microarray were performed. It was evidenced that maximal physiologically achievable concentrations of genistein (0.5-10 mu M) lead to significant increase in cell viability (p 10 mu M) appeared to have a novel mechanism of action, specifically down-regulating TGF-beta by decreasing specifically SMAD 2/3,4 which are in the downstream TGF-beta signaling cascade. Practical applications This study highlights for the first time that maximal physiologically achievable concentrations of genistein (0.5-10 mu M) have proliferative effects evidenced by alterations in global gene expression patterns of PC-3 cells. Our results particularly represent a closer examination of dietary genistein consumption for the prevention and/or treatment of cancer that maximal physiologically achievable concentrations of genistein could have detrimental effects on individuals with prostate cancer. Further studies as in vivo would be necessary to remove shadows on the effect of genistein on prostate cancer progression.

    Fresh tissue parathyroid allotransplantation with short-term immunosuppression: 1-year follow-up

    Background: Permanent hypoparathyroidism is a serious problem and requires medications indefinitely. Parathyroid allotransplantation (PA) with short-term immunosuppression is definitive choice but long-term results are not clear.

    Hipotiroidi Tedavisine Deneysel Alternatif Yöntem: Tiroid Dokusunun Kapsüle Edilmesi. Experimental Alternative Method for the Treatment of Hypothyroidism: Capsulation of the Thyroid Tissue.
    (2018-10-01T00:00:00Z) Yücesan, Emrah; Başoğlu, Harun; Özten Kandaş, Nur; Kanımdan, Ebru; Akbaş, Fahri; Ersoy, Yeliz Emine; Ayşan, Erhan; GÖNCÜ, BEYZA SERVET; AKBAŞ, FAHRİ; ERSOY, YELIZ EMINE
    Objective: Hypothyroidism is a clinical condition that affects all age groups. Generally, lifelong medication is required for the treatment. Despite treatment, symptoms that are related to hormone insufficiency and side effects due to long-term medication can be seen. As an alternative approach, thyroid tissue transplantation may be useful, because of its potential to elevate the thyroid hormone levels and thus increase daily quality of life for the patients. Our aim in this study was to detect the in vitro optimal microencapsulation conditions for thyroid tissues with a biocompatible polymer to avoid immune rejection following transplantation. Material and Methods: Thyroid tissues were isolated mechanically, and followed-up in two groups; tissue and capsulated tissue culture. In-vitro capsule formation and morphology were screened using brightfield microscopy and T3 and T4 levels were evaluated biochemically throughout 60 days. Results: T3 and T4 levels were screened from collected medium samples at day 3., 9., 12., 15., 30., 45., 60.. In capsuled tissues T3 level was detected higher than the non-capsuled and negative control tissues from day 15. However, T4 level was stable for 60 days.
