Accumulating data indicates that certain microRNAs (miRNAs or miRs) are differently expressed in samples of tumors and paired non-tumorous samples taken from the same patients with colorectal tumors. We previously reported to clarify the relationship between the expression of the miRNAs and the endoscopic morphological appearance of the colorectal tumors. In this report, we focused on colorectal adenoma (tubular or tubulovillous adenoma), or tubular early carcinoma or type 2 adenocarcinoma, familial adenomatous polyposis (FAP), ulcerative colitis-associated tumor (UCAT), and sessile serrated adenoma/polyp (SSA/P)...

BACKGROUND: Plasma pro-BNP (brain natriuretic peptide) levels are often elevated in response to right ventricular (RV) volume and pressure overload, parameters potentially affected by exercise. Plasma pro-BNP levels change in association with long-term changes in pulmonary hemodynamics, thereby serving as a potential biomarker in pulmonary arterial hypertension (PAH). The 6-min Walk Test (6MWT) and pro-BNP level are often checked in a single office visit. There is no universal standard for measuring Pro-BNP levels relative to the timing of the 6MWT...

Clinical isolates of Pseudomonas aeruginosa from patients with cystic fibrosis (CF) are known to differ from those associated with non-CF hosts by colony morphology, drug susceptibility patterns, and genomic hypermutability. Pseudomonas aeruginosa isolates from CF patients have long been recognized for their overall reduced rate of antimicrobial susceptibility, but their intraclonal MIC heterogeneity has long been overlooked. Using two distinct cohorts of clinical strains ( n = 224 from 56 CF patients, n = 130 from 68 non-CF patients) isolated in 2013, we demonstrated profound Etest MIC heterogeneity in CF P...

Multiple myeloma (MM) is a disease of copy number variants (CNVs), chromosomal translocations, and single-nucleotide variants (SNVs). To enable integrative studies across these diverse mutation types, we developed a capture-based sequencing platform to detect their occurrence in 465 genes altered in MM and used it to sequence 95 primary tumor-normal pairs to a mean depth of 104×. We detected cases of hyperdiploidy (23%), deletions of 1p (8%), 6q (21%), 8p (17%), 14q (16%), 16q (22%), and 17p (4%), and amplification of 1q (19%)...

Although most animal behaviors are associated with some form of heritable genetic variation, we do not yet understand how genes sculpt behavior across evolution, either directly or indirectly. To address this, I here compile a dataset comprised of over 1,000 genomic loci representing a spectrum of behavioral variation across animal taxa. Comparative analyses reveal that courtship and feeding behaviors are associated with genomic regions of significantly greater effect than other traits, on average three fold greater than other behaviors...

BACKGROUND: Understanding the diversity of repair outcomes after introducing a genomic cut is essential for realizing the therapeutic potential of genomic editing technologies. Targeted PCR amplification combined with Next Generation Sequencing (NGS) or enzymatic digestion, while broadly used in the genome editing field, has critical limitations for detecting and quantifying structural variants such as large deletions (greater than approximately 100 base pairs), inversions, and translocations...

A thorough understanding of the governing concepts of polarity behavior within electroencephalograph (EEG) promotes analytical and thus technical proficiency of the technologist by providing a skill set to logically resolve the myriad of waveform presentations that are expected across all montage derivations. In addition to avoiding a reliance on cursory conceptualization techniques, a solid grasp of the underlying theory of EEG polarity permits a fundamental realization of the cause-effect relationships between the various directions of eye movement and the resulting multitude of wave deflection presentations observed across all montages...

Tree peony ( Paeonia suffruticosa Andrews) is a perennial woody shrub bearing large and colorful flowers. However, the flowering period is short and relatively uniform, which to an important extent hinders the cultivation and exploitation of ornamental peonies. In this study, the segregation of an F₁ population derived from P. ostti 'Feng Dan' (an early-flowering cultivar) × P. suffruticosa 'Xin Riyuejin' (a late-flowering cultivar) was used to screen and analyze candidate genes associated with flowering period of the two parents...

OBJECTIVE: Observational studies suggest that obesity might have a Mendelian origin, but it is not clear if gene expression patterns observed in obese subjects are secondary to genetic traits or not. 
 Approach: Here we test a transcriptomic signature of obesity previously identified by our group
 on a large cohort of twin subjects (TwinsUK). 
 Main results: The results show that the signature correlates strongly both with the body mass index (BMI) and fat mass...

BACKGROUND: With the rapid advancement of array-based genotyping techniques, genome-wide association studies (GWAS) have successfully identified common genetic variants associated with common complex diseases. However, it has been shown that only a small proportion of the genetic etiology of complex diseases could be explained by the genetic factors identified from GWAS. This missing heritability could possibly be explained by gene-gene interaction (epistasis) and rare variants. There has been an exponential growth of gene-gene interaction analysis for common variants in terms of methodological developments and practical applications...

INTRODUCTION: Many patients are discharged from hospital with a peripherally inserted central catheter in place. Monitoring the peripherally inserted central catheter insertion site for clinical and research purposes is important for identifying complications, but the extent to which patients can reliably report the condition of their catheter insertion site is uncertain. The aim of this study was to assess the inter-observer agreement between nurses and patients when assessing a peripherally inserted central catheter site...
