Objective: Evaluate the diagnostic potential of plasma miR-200b-3p in oral squamous cell carcinoma (OSCC).
Materials and methods: miR-200b-3p was detected by qRT-PCR in paired pre-operative and post-operative plasmas from 80 OSCC patients and 80 healthy controls.
Results: Plasma miR-200b-3p was significantly upregulated in OSCC, and it was higher in WHO II/III grade than WHO I grade. The AUC of miR-200b-3p for OSCC was 0.9173. miR-200b-3p was significantly downregulated after surgery. High miR-200b-3p expression was associated with poor prognosis.
Discussion and conclusion: Plasma miR-200b-3p could be a potential diagnostic biomarker for OSCC. 相似文献
Objective: The objective of this study is to investigate the association between sleep-disordered breathing (SDB) – a source of oxidative stress – and CML.
Materials and methods: About 1002 participants in the Cardiovascular Health Study (CHS) were studied.
Results: Women with SDB had significantly higher CML concentration compared with those without SDB (OR?=?1.63, 95%CI?=?1.03–2.58, p?=?0.04). The association was not significant among men.
Discussion: SDB was associated with CML concentration among elderly women but not men in the Cardiovascular Health Study.
Conclusion: Accumulation of CML may be an adverse health consequence of SDB 相似文献

Aims: To explore which factors have more importance in determining the pre-fledging daily survival rates in a Yellow-legged Gull population from northern Iberia. Specifically, we tested for the effect of hatching date and order, body size and condition and meteorological conditions on pre-fledging survival.
Methods: Cormack–Jolly–Seber models with mixtures were used to model daily survival rates.
Results: Daily survival rates were mostly negatively affected by hatching date.
Conclusions: Hatching date was the most important factor affecting survival of chicks during the pre-fledging period in a Yellow-legged Gull colony from northern Iberia. 相似文献
Objective: To determine whether serum miR-1165-3p can serve as a potential diagnostic biomarker for allergic asthma.
Methods: Serum miR-1165-3p was quantified via quantitative real-time PCR (qRT-PCR) in asthmatic and control samples. Serum miR-1165-3p levels were compared between groups and the clinical diagnostic abilities of miR-1165-3p were evaluated. The analyses utilized included a student’s t test, one-way ANOVA, and the generation of receiver operating characteristic (ROC) curves.
Results: Serum miRNA-1165-3p levels were significantly elevated in asthmatics when compared to the healthy controls. Furthermore, the sensitivity and specificity of serum miR-1165-3p were found to be 83% and 68.2%. Additionally, serum miR-1165-3p levels were also found to be significantly elevated in patients with allergic rhinitis (AR) or allergic bronchopulmonary aspergillosis (ABPA).
Conclusions: This study showed that serum miR-1165-3p can potentially be utilized as a noninvasive biomarker that is able to aid in the diagnosis and characterization of allergic asthma. 相似文献

Materials and methods: A case–control study including 400 North Indians was performed using Polymerase Chain Reaction–Restriction Fragment Length Polymorphism (PCR-RFLP) approach to analyze genetic polymorphism.
Results: No significant difference was observed in genotype and allele frequencies of GNB3 gene on comparing cases with controls.
Discussion: Our study is in agreement with studies on Polish, Japanese, Hispanic-American and Danish populations who observed no significant association between GNB3 (C825T) polymorphism and T2DM.
Conclusion: GNB3 (C825T) polymorphism is not associated with T2DM. 相似文献
Objective: The aim of this study is to assess the prognostic value of leptin in patients with proven coronary artery disease (CAD) (N?=?1907).
Methods: AtheroGene is a contemporary CAD cohort study (N?=?3229). Median follow-up time was 3.8 (Quartile 1/3 with 2.8/4.9) years.
Results: Leptin concentration was associated with a hazard ratio (HR) for the fully adjusted model of HR?=?1.32 in women but was not significant in men. The endpoint cardiovascular death and non-fatal myocardial infarction was observed in 167 patients.
Conclusion: In women with known CAD, increased leptin concentration is useful for predicting cardiovascular death and non-fatal myocardial infarction. 相似文献
Objective: To analyse the relationships between serum leptin, vitamin D status, muscle strength and physical performance in OA patients.
Methods: A total of 208 knee OA patients were enrolled. Serum leptin, vitamin D, muscle strength and physical performance were evaluated.
Results: OA patients with sarcopenic obesity had significantly higher serum leptin levels than those with non-sarcopenic obesity. In addition, knee OA patients with sarcopenic obesity displayed low grip strength and poor physical performance. Furthermore, high serum leptin was negatively associated with vitamin D and physical performance.
Conclusions: Serum leptin levels were correlated with low vitamin D, reduced muscle strength and functional impairment, suggesting that serum leptin might serve as a biomarker reflecting physical performance in OA patients. 相似文献
Objective: The objective of this study is to identify the most recent advances in molecular biomarkers of diabetes and directions that warrant further research.
Methods: Using a systematic search strategy, the MEDLINE, CINAHL and OVID MEDLINE databases were canvassed for articles that investigated molecular biomarkers for diabetes. Initial selections were made based on article title, whilst final inclusion was informed by a critical appraisal of the full text of each article.
Results: The systematic search returned 246 records, of which 113 were unique. Following screening, 29 records were included in the final review. Three main research strategies (the development of novel technologies, broad biomarker panels, and targeted approaches) identified a number of potential biomarkers for diabetes including miR-126, C-reactive protein, 2-aminoadipic acid and betatrophin.
Conclusion: The most promising research avenue identified is the detection and quantification of micro RNA. Further, the utilisation of functionalised electrodes as a means to detect biomarker compounds also warrants attention. 相似文献

Methods: Big-ET-1 and NT-proBNP were determined in 2829 participants referred for coronary angiography (follow-up 9.9 years).
Results: Big-ET-1 is an independent predictor of total, CV mortality and death due to CHF.
Discussion: The conjunct use of Big-ET-1 and NT-proBNP improves the risk stratification of patients with intermediate to high risk of CV death and CHF.
Conclusions: Big-ET-1improves risk stratification in patients referred for coronary angiography. 相似文献
Methods: Secondary analyses of an observational clinical pilot study, including 60 patients with septic shock, 30 postoperative controls and 30 healthy volunteers.
Results: Plasma levels of sTREM-1 were found to identify patients with septic shock more effectively than procalcitonin and C-reactive protein. Moreover, sTREM-1 was identified to be an early predictor for survival in patients with septic shock.
Conclusion: Due to its diagnostic as well as prognostic value in sepsis syndrome, implementation of sTREM-1 measurements in routine diagnostics should be taken into account. 相似文献
Objectives: To investigate the prognostic value of IGF-I in patients admitted for acute decompensation of cirrhosis.
Materials and methods: Cohort study that included 103 patients. IGF-I was measured by enzyme-linked immunosorbent assay (ELISA).
Results: Ninety-day mortality was 26.2% and it was independently associated with MELD, age and IGF-I. The Kaplan–Meier survival probability at 90 days was 94.3% in patients with IGF-I?≥13?ng/mL and 63.2% for patients with IGF-I?<13?ng/mL (p?=?.001).
Discussion and conclusion: IGF-I levels are independently associated with mortality in acute decompensation of cirrhosis. 相似文献
Aims and objectives: To determine the expression of circulating miRNAs (miR-126, miR-92, miR-33, miR-145 and miR-155) in CAD patients of Indian origin.
Material and methods: miRNA profiling analysis in blood plasma was performed by quantitative real-time-PCR (qRT-PCR) in 60 angiographically verified subjects including 30 CAD patients and 30 age- and gender-matched controls. Association between the expression of all five circulating miRNAs and clinical characteristics of patients with CAD were analysed using Medcalc statistics. The severity of CAD was assessed using SYNTAX score (SS).
Results: Expression of plasma miR-33 increased by 2.9 folds in CAD patients than in control group (p value ≥0.002) also it was found that miR-33 expression levels in mild cases (SS: ≤22) were significantly higher than CAD controls. There was a modest negative correlation between miR-33 and total cholesterol/high density lipoprotein ratio, triglycerides and very low density lipoprotein.
Conclusion: The study reports a significant association between increased levels of plasma miR-33 and CAD. Thus, plasma miR-33 appears to be a promising non-invasive biomarker, but requires further validation in a large cohort. 相似文献
Objective: To build on previous work within the field, we examined biomarker kinetics in a rat model of acetaminophen (APAP)-induced liver injury to confirm the sensitivity, and specificity of miR-122 and glutamate dehydrogenase (GLDH).
Materials and methods: qRT-PCR and a standard enzymatic assay were used for biomarker analysis.
Results: Both miR-122 and GLDH were demonstrated to be more readily-detectable biomarkers of APAP-DILI than alanine aminotransferase (ALT). Peak levels for all biomarkers were detected at 2 days after APAP. At day 3, miR-122 had returned to baseline; however, other biomarkers remained elevated between 3 and 4 days. We were also able to demonstrate that, although miR-122 is present in greater quantities in exosome-free form, both exosome-bound and non-vesicle bound miR-122 are released in a similar profile throughout the course of DILI.
Discussion and conclusions: Together, this study demonstrates that both GLDH and miR-122 could be used during preclinical drug-development as complementary biomarkers to ALT to increase the chance of early detection of hepatotoxicity. 相似文献
