The role of circulating cell-free DNA and its integrity as a biomarker for diagnosis of breast cancer using ALU (247/115) bP sequences.

Diagnosis of breast cancer by using sensitive and specific biomarkers is necessary. Cell- free DNA (cf-DNA) is a candidate biomarker in various cancers. Contrasting, shorted uniformed DNA released from apoptotic non-diseased cells, DNA released from malignant cells varies in size.

Integrated microRNA and mRNA Expression Profiling Identifies Novel Targets and Networks Associated with Ebstein's Anomaly.

Little is known about abundance level changes of circulating microRNAs (miRNAs) and messenger RNAs (mRNA) in patients with Ebstein's anomaly (EA). Here, we performed an integrated analysis to identify the differentially abundant miRNAs and mRNA targets and to identify the potential therapeutic targets that might be involved in the mechanisms underlying EA. A large panel of human miRNA and mRNA microarrays were conducted to determine the genome-wide expression profiles in the blood of 16 EA patients and 16 age and gender-matched healthy control volunteers (HVs).

Insights from circulating microRNAs in cardiovascular entities in turner syndrome patients.

Background: Turner syndrome (TS) is a chromosomal disorder, in which a female is partially or entirely missing one of the two X chromosomes, with a prevalence of 1:2500 live female births. The present study aims to identify a circulating microRNA (miRNA) signature for TS patients with and without congenital heart disease (CHD).

Methods: Microarray platform interrogating 2549 miRNAs were used to detect the miRNA abundance levels in the blood of 33 TS patients and 14 age-matched healthy volunteer controls (HVs).

Th17/Treg cells imbalance and their related cytokines (IL-17, IL-10 and TGF-β) in children with autism spectrum disorder.

We aimed in this study to investigate a possible involvement of Th17/Treg cells imbalance in autism spectrum disorders (ASD). Using flowcytometry to determine circulating Th17 and Treg cells percentages, RT- PCR and ELISA for cytokine expression, we demonstrated that Th17/Treg balance in ASD children was significantly skewed toward a Th17 response compared to their control. Th17 cells and the ratio of Th17/Treg cells had a significantly positive correlation with disease severity whereas Treg cells had a negative correlation.

Characterization of micro-RNA Profile in the Blood of Patients with Marfan's Syndrome.

Background: Marfan's syndrome (MFS) is an autosomal dominant inheritance disorder with a 1/5,000 live-birth prevalence. It is characterized by a wide range of clinical manifestations with more than 3,000 mutations identified in the gene. In this study, we aimed to determine if specific patterns of circulating micro-RNAs (miRNAs) are associated with MFS-associated with cardiovascular diseases.

Assessment of regional atrial function in patients with hypertrophic cardiomyopathies using tissue Doppler imaging.

Background: This study applied tissue Doppler imaging and color tissue Doppler imaging to study atrial function changes in patients with hypertrophic cardiomyopathy (HCM). The profile of the segmental atrial velocities and the strain rate were determined and compared with those of normal matched control subjects.

Methods: This study investigated 20 patients with HCM and 20 age-matched healthy control subjects.

Transesophageal Three-Dimensional Echocardiographic Assessment of Normal and Stenosed Coronary Arteries.

We describe our preliminary experience in assessing normal and stenosed coronary arteries using transesophageal three-dimensional echocardiography (3-D echo) in 27 adult patients. Multiplane transesophageal two-dimensional images of the coronary arteries (20 left, 3 right, 3 both left and right, and 1 posterior descending) were first acquired in the TomTec computer in 3 degrees sequential increments, from 0 degrees to 180 degrees, and then 3-D reconstruction was performed. The entire left main (LMC, measuring 0.
