ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Background Zika, dengue, and chikungunya are three mosquito-borne viruses having overlapping transmission vectors. They cause diseases having similar symptoms in human patients, but requiring different immediate management steps.

Experimental increase of worker diversity benefits brood production in ants
Background The reproductive division of labor of eusocial insects, whereby one or several queens monopolize reproduction, evolved in a context of high genetic relatedness.

Molecular Evolution of Glycoproteins
Glycopeptides have been systematically classified based on the carbohydrate-peptide linkages and on the structure of carbohydrate units, and the hypotheses have been proposed regarding the evolution of these glycopeptides. Of seven types of carbohydrate-peptide linkages so far established, only glucosaminylasparagine linkage evolved in the proto ...

ABSTRACT Cup‐like nuclei are a distinctive morphological feature observed in certain cases of acute lymphoblastic leukemia (ALL). We provide evidence that they characterize DUX4/ERG ALL independently of IKZF1 deletion and reveal marked mitochondrial accumulation in this ALL subset.

ABSTRACT Primary cutaneous anaplastic large cell lymphoma (pcALCL) is a rare pediatric CD30‐positive T‐cell lymphoproliferative disorder with an excellent prognosis, but its genomic drivers are poorly defined. We report three children with skin‐limited disease demonstrating striking molecular heterogeneity, including NPM::ALK, NUP214::FRK, and a novel ...

Bacterial N4-methylcytosine as an epigenetic mark in eukaryotic DNA
Eukaryotic DNA can be methylated as 5-methylcytosine and N6-methyladenine, but whether other forms of DNA methylation occur has been controversial. Here the authors show that a bacterial DNA methyltransferase was acquired >60 Mya in bdelloid rotifers ...

Molecular Evolution of Paramyxoviruses.
We reviewed immunological relationships between paramyxoviruses and molecular evolution of paramyxoviruses. (1) paramyxoviruses are divided into two groups by the basis of the immunological relationship, i.e., parainfluenza type 1 virus group and type 2 virus group; (2) according to the NP and M proteins sequences, paramyxoviruses are divided into ...

Sociality and the Rate of Molecular Evolution [PDF]
The molecular clock does not tick at a uniform rate in all taxa but may be influenced by species characteristics. Eusocial species (those with reproductive division of labor) have been predicted to have faster rates of molecular evolution than their nonsocial relatives because of greatly reduced effective population size; if most individuals in a ...
