Morphological diversity (disparity) is a key component of biodiversity and increasingly a focus of botanical research. Despite the wide range of morphologies represented by pollen grains, to date there are few studies focused on the controls on pollen disparity and morphospace occupation, and fewer still considering these parameters in a phylogenetic framework. Here, we analyse morphospace occupation, disparity and rates of morphological evolution in Asterales pollen, in a phylogenetic context.

Fungal taxa described and illustrated in the present study include three new genera, 69 new species, one new combination, one reference specimen and 51 new records on new hosts and new geographical distributions. Three new genera, (), ( genus ) and () are introduced based on distinct phylogenetic lineages and unique morphologies.

Methods: Retrospective registry in 20 centers including patients over 75 years with AF treated with DES. A primary endpoint of MACCE and a co-primary endpoint of major bleeding by ISTH criteria were considered at 12 months.
A major climate shift took place about 40 Myr ago-the Middle Eocene Climatic Optimum or MECO-triggered by a significant rise of atmospheric CO concentrations. The biotic response to this MECO is well documented in the marine realm, but poorly explored in adjacent landmasses. Here, we quantify the response of the floras from America's southernmost latitudes based on the analysis of terrestrially derived spores and pollen grains from the mid-late Eocene (~46-34 Myr) of southern Patagonia.

In this study, we use a maximum likelihood framework to combine morphological and molecular traits to study the case of Xylodon australis (Hymenochaetales, Basidiomycota) using the locate.yeti function from the phytools R package.

Objectives: We sought to evaluate clinical outcomes in patients treated with the drug-eluting stent ihtDEStiny BD.
Background: The ihtDEStiny BD stent is a metallic sirolimus eluting stent with a biodegradable polymer with both drug and polymer coating the abluminal surface of the stent and balloon.
Methods: In this study, the clinical outcomes of a multicenter prospective registry of patients treated with this stent (DEStiny group) were analyzed and compared with those of a control group of patients treated with durable polymer everolimus or zotarolimus eluting stents (CONTROL group) paired by propensity score matching.
In this study, the taxonomic diversity of the species complex (, ) is examined. Specimens were studied using an integrative taxonomic approach that includes molecular phylogenetic and morphological analyses, and environmental niche comparisons. Four different species were found inside the complex, with a biogeographic distribution pattern bound by geographic regions: Europe, North America, Patagonia, and Australia-New Zealand.

The sensing system relies on coils of wire wrapped around the minor diameters of each bellows on the joint. As the bellows extend, these coils of wire become more distant, decreasing their mutual inductance.

The following loci were examined: the internal transcribed spacers of nuclear ribosomal DNA (ITS nrDNA), the intergenic spacers of nuclear ribosomal DNA (IGS nrDNA), two fragments of the protein-coding RNA polymerase II subunit 2 (2), and two fragments of the translation elongation factor 1-α (). Our results indicate that the name includes at least two separate species, one of which is newly described as .

The representative genome of strain KUC8140 was published in 2015 as part of the 1000 Fungal Genomes Project. Multilocus phylogenetic analyses, based on three nuclear regions (ITS, LSU and 2), confirmed a misidentification of strain KUC8140 which should be identified as .

Introduction: Pericallosal lipomas (PCL) are congenital soft masses of adipose cells encapsulated by a thin layer of fibrous tissue, appearing adjacent to the corpus callosum (CC). The lipomas are usually diagnosed prenatally during the third trimester. The purpose of this study was to identify 2nd trimester ultrasound findings that may hint to a later diagnosis of PCL and to evaluate their MRI evolution.

The aims were to recognize sculpturing patterns, under LM and SEM, within large and small pollen of both basal and derived species and to explore the features that could have taxonomic value to apply in palynological disciplines. The detailed examination of the exine surface showed both the relevance and limits of sculptural patterns for taxonomy.

Species of the genus Rhizopogon can be distinguished easily from the other hypogeous basidiomycetes by their lacunose gleba without columella and their smooth elliptical spores; however, the limit between species is not always easy to establish. Rhizopogon luteolus, the type species of the genus, has been considered one of the species that are more abundant in Europe, as well as it has been cited in pine plantation of North and South America, different parts of Africa, Australia, and New Zealand.

The Asteraceae (sunflowers and daisies) are the most diverse family of flowering plants. Despite their prominent role in extant terrestrial ecosystems, the early evolutionary history of this family remains poorly understood. Here we report the discovery of a number of fossil pollen grains preserved in dinosaur-bearing deposits from the Late Cretaceous of Antarctica that drastically pushes back the timing of assumed origin of the family.
