The First Miniature, Small Foliose, Brown in the Northern Hemisphere.

The genus includes several subcrustose, squamulose, small foliose, and small subfruticose species, primarily in the Southern Hemisphere. Here, we report on the first small foliose species lacking usnic acid in the genus occurring in the Holarctic. The species has been previously known as Nyl.

Pea Seed Priming with Pluronic P85-Grafted Single-Walled Carbon Nanotubes Affects Photosynthetic Gas Exchange but Not Photosynthetic Light Reactions.

Nanotechnology is rapidly advancing towards the development of applications for sustainable plant growth and photosynthesis optimization. The nanomaterial/plant interaction has been intensively investigated; however, there is still a gap in knowledge regarding their effect on crop seed development and photosynthetic performance. In the present work, we apply a priming procedure with 10 and 50 mg/L Pluronic-P85-grafted single-walled carbon nanotubes (P85-SWCNT) on garden pea seeds and examine the germination, development, and photosynthetic activity of young seedlings grown on soil substrate.

Pancreatic steatosis and iron overload increases cardiovascular risk in non-alcoholic fatty liver disease.

Method: A prospective, multicenter study including NAFLD patients with biopsy and paired Magnetic Resonance Imaging (MRI) was performed. Liver biopsies were evaluated according to NASH Clinical Research Network, hepatic iron storages were scored, and digital pathology quantified the tissue proportionate areas of fat and iron.

Targeting shared molecular etiologies to accelerate drug development for rare diseases.

Rare diseases affect over 400 million people worldwide and less than 5% of rare diseases have an approved treatment. Fortunately, the number of underlying disease etiologies is far less than the number of diseases, because many rare diseases share a common molecular etiology. Moreover, many of these shared molecular etiologies are therapeutically actionable.

Physicochemical Modifications on Thin Films of Poly(Ethylene Terephthalate) and Its Nanocomposite with Expanded Graphite Nanostructured by Ultraviolet and Infrared Femtosecond Laser Irradiation.

In this work, the formation of laser-induced periodic surface structures (LIPSS) on the surfaces of thin films of poly(ethylene terephthalate) (PET) and PET reinforced with expanded graphite (EG) was studied. Laser irradiation was carried out by ultraviolet (265 nm) and near-infrared (795 nm) femtosecond laser pulses, and LIPSS were formed in both materials. In all cases, LIPSS had a period close to the irradiation wavelength and were formed parallel to the polarization of the laser beam, although, in the case of UV irradiation, differences in the formation range were observed due to the different thermal properties of the neat polymer in comparison to the composite.

Biodiversity Patterns and Ecological Preferences of the Photobionts Associated With the Lichen-Forming Genus .

The worldwide, ecologically relevant lichen-forming genus currently includes 41 accepted species, of which the group (PSULgp) and the group (PSAXgp) have received considerable attention over recent decades; however, phycobiont diversity is poorly known in s. lat. Here, we studied the diversity of microalgae associated with 159 thalli collected from 30 locations, including nine spp.

Pultruded FRP Beams with Embedded Fibre Bragg Grating Optical Sensors for Strain Measurement and Failure Detection.

Composites have added new dimensions to the design and construction of buildings and structures. One of the wider spread composite applications in the construction industry is composite beams or pillars, which can be manufactured through pultrusion processes. These types of construction elements are usually used to withstand the weight of large loads, so their integrity must be guaranteed.

First Report of Cucurbit chlorotic yellows virus infecting Cucumber Plants in Spain.

During the winter 2018, symptoms of leaf chlorotic spots (Figure 1) followed by symptoms of leaf interveinal chlorosis (Figure 2) and severe chlorosis in basal leaves were observed in cucumber cv Laredo (Cucumis sativus) plants in three separated greenhouses, sited in distinct locations in southern Spain. In all cases, Bemisia tabaci populations were observed on infected plants. The symptomology observed was similar to that caused by whitefly transmitted Cucurbit yellow stunting disorder virus (CYSDV, genus Crinivirus, family Closteroviridae), which is usually found infecting cucumber plants in this geographical area (1).

Thiopurine adherence: a high prevalence with low impact on UC outcomes.

Introduction: thiopurines are used as maintenance therapy in patients with ulcerative colitis (UC). There are contradictory results regarding the relationship between adherence to treatment and risk of relapse.

Objectives: to quantify and evaluate the trends in thiopurine prescription rates, and to determine the impact and risk factors of non-adherence.

Genome-Wide Analysis of Biosynthetic Gene Cluster Reveals Correlated Gene Loss with Absence of Usnic Acid in Lichen-Forming Fungi.

Lichen-forming fungi are known to produce a large number of secondary metabolites. Some metabolites are deposited in the cortical layer of the lichen thallus where they exert important ecological functions, such as UV filtering. The fact that closely related lineages of lichen-forming fungi can differ in cortical chemistry suggests that natural product biosynthesis in lichens can evolve independent from phylogenetic constraints.

Chronic Venous Insufficiency as a Predisposing Factor for Basal Cell Carcinoma on Legs.

Background: The main risk factor associated with basal cell carcinomas (BCCs) is believed to be exposure to ultraviolet radiation (UVR). In the case of lower limb BCC, the frequency is higher in women, possibly because of greater exposure of the leg to UVR. Chronic venous insufficiency (CVI), also more common in women, may have some association with leg BCCs.

Whole-Genome Sequence Data Uncover Widespread Heterothallism in the Largest Group of Lichen-Forming Fungi.

Fungal reproduction is regulated by the mating-type (MAT1) locus, which typically comprises two idiomorphic genes. The presence of one or both allelic variants at the locus determines the reproductive strategy in fungi-homothallism versus heterothallism. It has been hypothesized that self-fertility via homothallism is widespread in lichen-forming fungi.

gen. nov. and (Lecanorales, Protoparmelioideae): species description and generic delimitation using DNA barcodes and phenotypical characters.

Multilocus phylogenetic studies revealed a high level of cryptic diversity within the lichen-forming fungal genus (Protoparmelioideae, Parmeliaceae). Coalescent-based species delimitation suggested that most of the cryptic molecular lineages warranted recognition as separate species. Here we study the morphology and chemistry of these taxa and formally describe eight new species based on phenotypical and molecular characters.

Environment and host identity structure communities of green algal symbionts in lichens.

An understanding of how biotic interactions shape species' distributions is central to predicting host-symbiont responses under climate change. Switches to locally adapted algae have been proposed to be an adaptive strategy of lichen-forming fungi to cope with environmental change. However, it is unclear how lichen photobionts respond to environmental gradients, and whether they play a role in determining the fungal host's upper and lower elevational limits.

Protective effects of lichen metabolites evernic and usnic acids against redox impairment-mediated cytotoxicity in central nervous system-like cells.

Lichens species produce unique secondary metabolites that attract increasing pharmacological interest, including their redox modulatory activities. Current work evaluated for the first time the in vitro cytoprotective properties, based on the antioxidant activities, of the Parmeliaceae lichens Evernia prunastri and Usnea ghattensis and the mechanism of action of their major phenolic constituents: the evernic and usnic acids, respectively. In two models of central nervous system-like cells (U373-MG and SH-SY5Y cell lines), exogenous HO induced oxidative stress-mediated cytotoxicity.

Panmixia and dispersal from the Mediterranean Basin to Macaronesian Islands of a macrolichen species.

The Mediterranean region, comprising the Mediterranean Basin and the Macaronesian Islands, represents a center of diversification for many organisms. The genetic structure and connectivity of mainland and island microbial populations has been poorly explored, in particular in the case of symbiotic fungi. Here we investigated genetic diversity and spatial structure of the obligate outcrossing lichen-forming fungus Parmelina carporrhizans in the Mediterranean region.

In vitro neuroprotective potential of lichen metabolite fumarprotocetraric acid via intracellular redox modulation.

The lichen-forming fungi Cetraria islandica has been largely used in folk medicines, and it has recently showed promising in vitro antioxidant effects in glial-like cells. Current work aimed at investigating the neuroprotective potential of its major isolated secondary metabolite: the depsidone fumarprotocetraric acid (FUM). HO was used herein to induce oxidative stress (OS)-mediated cytotoxicity in two models of neurons and astrocytes cells (SH-SY5Y and U373-MG cell lines).
