    Background/aim: MicroRNAs (miRNAs) are known up-to-date candidate biomarkers for several diseases. In addition, obtaining miRNA from different body fluids such as serum, plasma, saliva, and urine is relatively easy to handle. Herein we aimed to detect miRNAs as biomarkers for early stage prostate cancer (PC). For this purpose, we used urine and serum samples to detect any significant differences in miRNA profiles between patients and healthy controls. Materials and methods: Total ribonucleic acid (RNA) in urine and serum samples were isolated from eight untreated PC patients, thirty healthy individuals were screened for miRNA profile, and candidate miRNAs were validated. Whole urinary and serum miRNA profile was analyzed using Affymetrix GeneChip miRNA 4.0 Arrays. Candidate miRNAs were investigated by stem-loop reverse transcription- polymerase chain reaction. Results: When we analyzed the urinary samples of PC patients, 49 miRNAs were detected to be upregulated and 14 miRNAs were found to be downregulated when compared with healthy controls. According to the serum samples, 19 miRNAs were found to be upregulated, and 21 miRNAs were found to be downregulated when compared with healthy individuals as well. Interestingly, we detected only four overlapping miRNAs (MIR320A, MIR4535, MIR4706, MIR6750) that commonly increase or decrease in both serum and urine samples. Among them, MIR320A was found to be downregulated, and MIR4535, MIR4706, and MIR6750 were found to be upregulated for urine samples. However, only MIR6750 was upregulated and the other three miRNAs were downregulated for serum samples. Conclusion: Notably, the expression profile of MIR320A was significantly altered in urine specimens of prostate cancer patients. We considered that MIR320A has been evaluated as a valuable biomarker that can be used in the early diagnosis of PC.

    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.
