Mapping quantitative trait loci regions associated with Marek's disease on chicken autosomes by means of selective DNA pooling.

Marek's Disease (MD), which can result in neurological damage and tumour formation, has large effects on the economy and animal welfare of the poultry industry worldwide. Previously, we mapped autosomal MD QTL regions (QTLRs) by individual genotyping of an F population from a full-sib advanced intercross line. We further mapped MD QTLRs on the chicken Z chromosome (GGZ) using the same F population, and by selective DNA pooling (SDP) of 8 elite egg production lines.

Learned phenotypes emerge during social stress modifying hippocampal orexin receptor gene expression.

Psychological distress, including anxiety or mood disorders, emanates from the onset of chronic/unpredictable stressful events. Symptoms in the form of maladaptive behaviors are learned and difficult to treat. While the origin of stress-induced disorders seems to be where learning and stress intersect, this relationship and molecular pathways involved remain largely unresolved.

Functional anatomy of zinc finger antiviral protein complexes.

ZAP is an antiviral protein that binds to and depletes viral RNA, which is often distinguished from vertebrate host RNA by its elevated CpG content. Two ZAP cofactors, TRIM25 and KHNYN, have activities that are poorly understood. Here, we show that functional interactions between ZAP, TRIM25 and KHNYN involve multiple domains of each protein, and that the ability of TRIM25 to multimerize via its RING domain augments ZAP activity and specificity.

Donor derived cell free DNA in lung transplant recipients rises in setting of allograft instability.

Purpose: The purpose of this study was to evaluate the correlation between longitudinal monitoring of donor-derived cell free DNA (dd-cfDNA) in lung transplant recipients and a "gold standard" of existing tools (pulmonary function testing, radiographic imaging, laboratory and bronchoscopy data, clinical judgment) to assess allograft function.

Methods: 24 consecutive transplant recipients were prospectively enrolled in this study measuring dd-cfDNA levels monthly in the first year after bilateral lung transplant. Blinded clinical adjudications were performed at the same timepoints to categorize allograft function as stable (FEV1 within 10% of prior value or when compared to best two averaged post-transplant values) or unstable.

The ADHD Assessment Quality Assurance Standard for Children and Teenagers (CAAQAS).

Around 5% of the children and teenagers worldwide are affected by Attention-Deficit/Hyperactivity Disorder [ADHD], making it a major public health concern. Recently, demand for assessments has substantially increased, putting strain on healthcare and waiting lists. There is concern that pressure to clear service bottlenecks is leading to variable quality and reliability of ADHD assessments in this population.
