BACKGROUND: Transposable elements (TEs) are interspersed DNA sequences that can move or copy to new positions within a genome. TEs are believed to promote speciation and their activities play a significant role in human disease. In the human genome, the 22 AluY and 6 AluS TE subfamilies have been the most recently active, and their transposition has been implicated in many inherited human diseases and in various forms of cancer. Therefore, understanding their transposition activity is very important and identifying the factors that affect their transpositional activity is of great interest...

Transposable elements (TEs) have shown a great significance in regulatory elements research, being responsible for different types of cancers. They are divided into three classes on the basis of their mode of transposition, structural properties, and their homology with DNA sequence. In evaluating their role in cancers and other pathologies, researchers have found extensive evidence of their involvement. TEs can also be used as genetic markers for cancers and help in identifying potential therapeutic targets...

In many parts of the world, mostly low- and middle-income countries, timely diagnosis and repair of congenital heart diseases (CHDs) is not feasible for a variety of reasons. In these regions, economic growth has enabled the development of cardiac units that manage patients with CHD presenting later than would be ideal, often after the window for early stabilisation - transposition of the great arteries, coarctation of the aorta - or for lower-risk surgery in infancy - left-to-right shunts or cyanotic conditions...

BACKGROUND: Junctional ectopic tachycardia (JET) after congenital heart disease (CHD) surgery is often self-limiting but is associated with increased risk of morbidity and mortality. Contributing factors and impact of time to achieve rate control of JET are poorly described. METHODS: From January 2010 to June 2015, a retrospective, single-center cohort study was performed of children who developed JET after CHD surgery . We classified the cohort into two groups: patients who achieved rate control of JET in ≤24 hours and in >24 hours...

Acute and chronic respiratory diseases account for major causes of illness and deaths worldwide. Recent developments of biotherapeutics opened a new era in the treatment and management of patients with respiratory diseases. When considering the delivery of therapeutics, the inhaled route offers great promises with a direct, non-invasive access to the diseased organ and has already proven efficient for several molecules. To assist in the future development of inhaled biotherapeutics, experimental models are crucial to assess lung deposition, pharmacokinetics, pharmacodynamics and safety...

Congenitally corrected transposition of great arteries (CCTGA) is a rare anomaly described by atrioventricular and ventriculoarterial discordance. On the other hand, mesocardia that is extremely rare includes two relatively well-defined apexes defined by each ventricle with the major axis of the heart lies in the midline. We describe a rare case of an asymptomatic 20-year-old woman with mesocardia, CCTGA, and severe subvalvular pulmonic stenosis due to a ball-shaped accessory tissue in left ventricular outflow tract...

BACKGROUND: Children with major congenital heart defects are risking impaired cerebral growth, delayed cerebral maturation, and neurodevelopmental disorders. We aimed to compare the cerebral tissue oxygenation of fetuses with major heart defects to that of fetuses without heart defects as estimated by the magnetic resonance imaging modality T2*. T2* is low in areas with high concentrations of deoxyhemoglobin. METHODS AND RESULTS: At gestational age mean 32 weeks (early) and mean 37 weeks (late), we compared the fetal cerebral T2* in 28 fetuses without heart defects to that of 15 fetuses with major heart defects: transposition of the great arteries (n=7), coarctation of the aorta/hypoplastic aortic arch (n=5), tetralogy of Fallot (n=1), hypoplastic right heart (n=1), and common arterial trunk (n=1)...

Purpose of this study was to investigate a potential correlation between the pattern of cerebral veins (CV) on susceptibility-weighted imaging (SWI) and blood oxygen saturation, as well as preoperative brain injury, in neonates with transposition of the great arteries (TGA). Eleven neonates with TGA underwent MRI preoperatively, including SWI, T1- and T2-weighted scans. Images were retrospectively evaluated and appearance of CV was graded from 0 (normal appearance) to 3 (severe prominent appearance). White matter injuries (WMI) and strokes were analysed...

We experienced an arterial switch operation in a patient with d-transposition of the great arteries associated with bilateral intramural coronary arteries from a single coronary ostium. In performing the coronary transfer, intramural course of bilateral coronary arteries was unroofed and coronary ostium was separated into two coronary buttons. The two coronary buttons were translocated to the neo-aorta using modified trap-door technique. The angiogram performed 6 years after the operation revealed well-developed coronary arteries without stenosis, and the patient is doing well 8 years after the operation...

The common heart diseases resulting in a brain abscess are associated with a right to left shunt and include tetralogy of Fallot and transposition of great vessels. Atrial septal defect (ASD) is almost always associated with the left to right shunt and therefore is not a commonly considered risk factor for brain abscess. We report the case of a 29-year-old male, with no symptoms of cardiac disease, who presented with the left posterior frontal pyogenic abscess which led to the detection of a silent ASD. Our case emphasizes the need for a careful evaluation of the source of infection in patients with a brain abscess...

Studies have highlighted the critical role of GATA6 in conotruncal heart defects (CTDs). Nevertheless, relationship between GATA6 variants and different CTDs remains largely unknown. Here GATA6 gene was screened in 542 patients with CTDs using targeted sequencing. Variant frequency was 2.0% (11/542). Three novel variants: c.86C>A (p.A29E), c.296T>A (p.V99D) and c.1254delC (p.S418fs) were identified in patients with transposition of the great arteries, double outlet right ventricle and persistent truncus arteriosus, respectively, but in none of the 400 controls...

Coronary complications in patients with transposition of the great arteries (TGA) after an arterial switch operation (ASO) are relatively rare, but of all the possible postoperative adverse events, they are potentially the most dangerous. The fate of the coronary arteries, which are transplanted during the neonatal ASO, remains uncertain. There is also no consensus regarding their postoperative evaluation, especially in asymptomatic patients. The aim of this study was to present the early results of routinely performed coronary computed tomography angiography (CCTA) in asymptomatic adolescents and young adults with TGA after an ASO...

Hong Jo Lee, Young Min Kim, Tamao Ono, Jae Yong Han
The rapid development of genome modification technology has provided many great benefits in diverse areas of research and industry. Genome modification technologies have also been actively used in a variety of research areas and fields of industry in avian species. Transgenic technologies such as lentiviral systems and piggyBac transposition have been used to produce transgenic birds for diverse purposes. In recent years, newly developed programmable genome editing tools such as transcription activator-like effector nuclease (TALEN) and clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (CRISPR/Cas9) have also been successfully adopted in avian systems with primordial germ cell (PGC)-mediated genome modification...
