Near-infrared system's efficiency for peripheral intravenous cannulation in a level III neonatal intensive care unit: a cross-sectional study.

Venipuncture is a painful and invasive procedure for hospitalised newborns and represents a challenge for neonatal healthcare professionals. This study evaluated the most efficient cannulation method based on the proportion of success at the first attempt, standard care or near-infrared (NIR) device use, and pain assessment. An observational study with two arms was conducted in the neonatal intensive care unit (NICU) of a tertiary-care university hospital in Italy.

Population genomic analyses of RAD sequences resolves the phylogenetic relationship of the lichen-forming fungal species and .

Neuropogonoid species in the lichen-forming fungal genus exhibit great morphological variation that can be misleading for delimitation of species. We specifically focused on the species delimitation of two closely-related, predominantly Antarctic species differing in the reproductive mode and representing a so-called species pair: the asexual and the sexual . Previous studies have revealed contradicting results.

The use of microsatellite markers for species delimitation in Antarctic Usnea subgenus Neuropogon.

Lichens are symbiotic associations consisting of a fungal (mycobiont) and one or more photosynthetic (photobionts) partners and are the dominant component, and most important primary producers, of Antarctic terrestrial ecosystems. The most common lichens in the maritime Antarctic are Usnea antarctica and U. aurantiacoatra, a so-called "species pair" in which U.

Fungus-specific SSR markers in the Antarctic lichens and (Parmeliaceae, Ascomycota).

Premise Of The Study: and (Parmeliaceae) are common lichens in the maritime Antarctic. These species share the same habitats on King George Island (South Shetland Islands, Antarctica) and are distinguishable based on reproductive strategies.

Methods And Results: We developed 23 fungus-specific simple sequence repeat (SSR) markers that cross-amplify between the two species.

Selection processes in simple sequence repeats suggest a correlation with their genomic location: insights from a fungal model system.

Background: Adaptive processes shape the evolution of genomes and the diverse functions of different genomic regions are likely to have an impact on the trajectory and outcome of this evolution. The main underlying hypothesis of this study is that the evolution of Simple Sequence Repeats (SSRs) is correlated with the evolution of the genomic region in which they are located, resulting in differences of motif size, number of repeats, and levels of polymorphisms. These differences should be clearly detectable when analyzing the frequency and type of SSRs within the genome of a species, when studying populations within a species, and when comparing closely related sister taxa.
