    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.

    Paratiroit allotransplantasyonu (PA-t) kalıcı hipoparatiroidili (KH) olgularda önemli ve görece yeni bir tedavi yöntemidir. Ancak donanımlı laboratuvar alt yapısı ile birlikte deneyimli ve multidisipliner bir ekip gerektirdiği için uygulanması güç bir süreçtir. Bu makalede Türkiye-de Sağlık Bakanlığından ruhsatlı ilk PA-t merkezinde yapılan, literatürdeki en geniş ikinci olgu serisini sunduk. Nakil için, bilgilendirilmiş onamı alınan, segonder hiperparatiroidisi olan kronik böbrek yetmezliği tanılı hastalardan alınan dokular kullanıldı. Bu dokulardan paratiroit hücreleri izole edildi, süspansiyon haline getirildi, 3-4 günlük kültür işleminden sonra KH tanısı olan 44 hastaya (12 erkek, 32 kadın, ortalama yaş: 44,5) transplante edildi. On gün süreyle, aşamalı olarak azalan dozlarda prednizolon uygulaması dışında kalıcı immunsupresyon yapılmadı. Ortalama 16 (1-26) aylık takipte, 32 (%72,7) hastada allograft fonksiyonu görüldü. Bu hastalarda oral ve/veya intravenöz kalsyum ve D vitamini desteği kesildi. Hiçbir hastada komplikasyon gözlenmedi. KH tanılı olguların tedavisinde kalıcı immunsupresyon yapılmaksızın PA-t, komplikasyon riski olmayan, etkin bir tedavi yöntemidir.
