Strategies in skeletal regeneration research have been primarily focused on optimization of three components: cellular progenitors, biomaterials, and growth factors. With the increased understanding that circulating progenitor cells exist in peripheral blood, the question arises whether such cell types would allow for adequate osteogenesis and mineralization. In this review, we discuss the curr...

objectives: to critically evaluate the effect of red clover on hot flash, endometrial thickness, and hormones status in postmenopausal and peri- and post-menopausal women. materials and methods: medline (1966 to july 2014), scopus (1990 to july 2014), and the cochrane central register of controlled trials (the cochrane library issue 1, 2014) were searched for published randomized controlled tri...

MicroRNAs (miRNAs) are small noncoding RNAs that regulate gene expression at the post-transcriptional level. Current studies have shown that miRNAs are also present in extracellular spaces, packaged into various membrane-bound vesicles, or associated with RNA-binding proteins. Circulating miRNAs are highly stable and can act as intercellular messengers to affect many physiological processes. Mi...

Both renin and its biosynthetic precursor, prorenin, are secreted into the circulation of mammals. Although the circulating levels of prorenin can exceed those of renin by as much as 100-fold in certain conditions, there is no evidence that prorenin contributes to the synthesis of circulating angiotensin peptide synthesis or increased blood pressure (BP). In the current study, we have generated...

Relapse remains the major cause of mortality for patients with Acute Myeloid Leukemia (AML). Improved tracking of minimal residual disease (MRD) holds the promise of timely treatment adjustments to preempt relapse. Current surveillance techniques detect circulating blasts that coincide with advanced disease and poorly reflect MRD during early relapse. Here, we investigate exosomes as a minimall...

MicroRNAs (miRs) are small, noncoding RNAs that posttranscriptionally control gene expression by inhibiting protein translation or inducing target mRNA destabilization. Besides their intracellular function, recent studies demonstrate that miRs can be exported or released by cells and circulate with the blood in a remarkably stable form. The discovery of circulating miRs opens up intriguing poss...

To identify novel non-invasive biomarkers for improved detection, risk assessment and prognostic evaluation of cancer, expression profiles of circulating microRNAs are currently under evaluation. Circulating microRNAs are highly promising candidates in this context, as they present some key characteristics for cancer biomarkers: they are tissue-specific with reproducible expression and consiste...

Chronic heart failure (CHF) remains a leading cause of morbidity and mortality. In the current study, we aimed to evaluate the predictive value of circulating thrombospondin-2 (TSP-2) for cumulative survival in patients with ischemic CHF due to coronary artery disease (CAD). The results showed that during a median follow-up of 2.18 years, 21 participants died and 106 subjects were hospitalized ...

INTRODUCTION Monitoring of circulating blood volume is important in the management of critically ill patients. Current methods of circulating blood volume measurements such as indicator dilution using radioisotopes or Evans blue dye are unsuitable for clinical application as these tests do not allow for frequent repeated measurements to be done. A direct bedside measurement of circulating blood...

PURPOSE Current lung cancer staging and prognosis methods are based on imaging methods, which may not be sensitive enough for early and accurate detection of metastasis. This study aims to validate the use of a panel of markers for circulating cancer cell detection to improve the accuracy of cancer staging, prognosis, and as a rapid assessment of therapeutic response. EXPERIMENTAL DESIGN We a...
