Sarcoidosis is a systemic granulomatous disease including heart (cardiac sarcoidosis, CS). It has recently been reported that isolated CS, which presenting primarily cardiac symptoms without clinical evidence of sarcoid involvement in other organs. Diagnostic and prognostic biomarkers of CS, especially in isolated CS, have not yet been established.We studied plasma levels of angiotensin-converting enzyme (ACE), soluble interleukin-2 receptor (sIL-2R), B-type natriuretic peptide (BNP) and cardiac troponin I (cTnI) in consecutive 172 patients with diagnosed sarcoidosis...

BACKGROUND: Biomarker candidates are often ranked using P-values. Standard P-value calculations use normal or logit-normal approximations, which may not be correct for small P-values and small sample sizes common in discovery research. METHODS: We compared exact P-values, correct by definition, with logit-normal approximations in a simulated study of 40 cases and 160 controls. The key measure of biomarker performance was sensitivity at 90% specificity. Data for 3000 uninformative false markers and 30 informative true markers were generated randomly...

The use of blood biomarkers for stroke has been long considered an excellent method to determine the occurrence, timing, subtype, and severity of stroke. In this study, venous blood was obtained from ischemic stroke patients after stroke onset and compared with age and sex-matched controls. We used a multiplex panel of 37 inflammatory molecules, analyzed using Luminex MagPix technology, to identify the changes in plasma proteins after ischemic stroke. We identified eight key molecules that were altered within the blood of stroke patients as compared to controls...

BACKGROUND: MicroRNAs (miRNAs) hold promise as diagnostic cancer biomarkers. Here we aimed to define the miRNome in oral squamous cell carcinoma (OSCC) and normal oral mucosa (NOM), and to identify and validate new diagnostic miRNAs and miRNA combinations in formalin-fixed paraffin-embedded (FFPE) tissue samples and plasma samples. METHODS: We performed next-generation miRNA sequencing in FFPE tissue samples of OSCC (n = 80) and NOM (n = 8). Our findings were validated by quantitative polymerase chain reaction (qPCR) analysis of OSCC (n = 195) and NOM (n = 103) FFPE tissue samples, and plasma samples from OSCC patients (n = 55) and healthy persons (n = 18)...

The early detection of lung cancer is a major clinical challenge. Long noncoding RNAs (lncRNAs) have important functions in tumorigenesis. Plasma lncRNAs directly released from primary tumors or the circulating cancer cells might provide cell-free cancer biomarkers. The objective of this study was to investigate whether the lncRNAs could be used as plasma biomarkers for early-stage lung cancer. By using droplet digital polymerase chain reaction, we determined the diagnostic performance of 26 lung cancer-associated lncRNAs in plasma of a development cohort of 63 lung cancer patients and 33 cancer-free individuals, and a validation cohort of 39 lung cancer patients and 28 controls...

The αvβ3 integrin has been shown to promote aggressive phenotypes in many types of cancers, including prostate cancer. We show that GFP-labeled αvβ3 derived from cancer cells circulates in the blood and is detected in distant lesions in NOD scid gamma (NSG) mice. We therefore hypothesized that αvβ3 travels through exosomes and we tested its levels in pools of vesicles, which we designate extracellular vesicles highly enriched in exosomes (ExVs), and in exosomes isolated from the plasma of prostate cancer patients...

C-reactive protein (CRP) is an acute-phase plasma protein that can be used as a biomarker for activation of the immune system. A spectral analysis of CRP level over time for patients with gynaecological tumours has been reported by Madondo et al., using a periodogram method, suggesting that there is no significant periodicity in the data. In our study, we investigate the impact of low sample number on periodogram analysis, for non-uniform sampling intervals-we conclude that data of Madondo et al. cannot rule out periodic behaviour...

BACKGROUND AND PURPOSE: Radiochemotherapy is a standard treatment option for patients with head and neck cancer (HNSCC). During radiation, local toxicities are common and need to be differentiated from infections. As levels of circulating cell-free DNA (cfDNA) are known to be elevated during infections, cfDNA might complement clinical parameters. The aim of the study was to investigate the dynamics of cfDNA during radiochemotherapy. MATERIAL AND METHODS: In total, 78 blood samples of 20 patients with HNSCC were analysed in this prospective biomarker study...

The embryonic mortality in cows is a growing concern for an ever-expanding dairy industry. The current study was an attempt to shorten the open period of dairy cows having suffered embryonic loss by diagnosing them at an earlier stage. The blood samples were collected from the Karan Fries (KF) cows on days 0 (day of AI/estrus), 4, 8, 12, 14, 16, 18, 21, 24, 28, 35 and 42 post insemination. The experimental animals were then categorized into pregnant (P), conception failure/early embryonic mortality (EEM) and late embryonic mortality cows (LEM), based on progesterone assay, ultrasonography and per-rectal palpation...
