Subtelomeric plasticity contributes to gene family expansion in the human parasitic flatworm Schistosoma mansoni.

Background: The genomic region that lies between the telomere and chromosome body, termed the subtelomere, is heterochromatic, repeat-rich, and frequently undergoes rearrangement. Within this region, large-scale structural changes enable gene diversification, and, as such, large multicopy gene families are often found at the subtelomere. In some parasites, genes associated with proliferation, invasion, and survival are often found in these regions, where they benefit from the subtelomere's highly plastic, rapidly changing nature.

Benefits of a ketogenic diet on repetitive motor behavior in mice.

Repetitive motor behaviors are repetitive and invariant movements with no apparent function, and are common in several neurological and neurodevelopmental disorders, including autism spectrum disorders (ASD). However, the neuropathology associated with the expression of these abnormal stereotypic movements is not well understood, and effective treatments are lacking. The ketogenic diet (KD) has been used for almost a century to treat intractable epilepsy and, more recently, disorders associated with inflexibility of behavioral routines.

Esmolol Compared with Amiodarone in the Treatment of Recent-Onset Atrial Fibrillation (RAF): An Emergency Medicine External Validity Study.

Background: Recent-onset atrial fibrillation (RAF) is the most frequent supraventricular dysrhythmia in emergency medicine. Severely compromised patients require acute treatment with injectable drugs OBJECTIVE: The main purpose of this external validity study was to compare the short-term efficacy of esmolol with that of amiodarone to treat severe RAF in an emergency setting.

Methods: This retrospective survey was conducted in mobile intensive care units by analyzing patient records between 2002 and 2013.

Pain Assessment in Newborns, Infants, and Children.

Pain in children is underestimated and undertreated because of lack of pain assessment tools. Pain assessment depends on the cognitive development of the child being tested, clinical context, and pain typology. For children older than age 6 years, pain assessment is based on a self-report.

Pain Assessment in Children Younger Than 8 Years in Out-of-Hospital Emergency Medicine: Reliability and Validity of EVENDOL Score.

Objective: Pain in children is underestimated and undertreated in out-of-hospital emergency medicine. In this setting, caregivers need a reliable pain scale, but none has been validated. A single observational pain scale for all children younger than 8 years, EVENDOL, has been validated in emergency pediatric units.
