Ramial chipped wood amendment drives shifts in soil microbial carbon and phosphorus cycling networks across a depth gradient
Soil regeneration depends on microbial processes driving nutrient cycling and organic matter retention. Ramial chipped wood (RCW), a carbon-rich organic amendment, stimulates microbial activity and may promote shortterm ...
Differential impact of impaired steryl ester biosynthesis on the metabolome of tomato fruits and seeds
Steryl esters (SE) are a storage pool of sterols that accumulates in cytoplasmic lipid droplets and helps to maintaining plasma membrane sterol homeostasis throughout plant growth and development. Ester formation of plant ...
Genetic diversity of <em>Phlebotomus perniciosus</em>populations between insular and mainland regionsin the leishmaniasis-endemic westernMediterranean area
Phlebotomus perniciosus</em> is the primary vector of <em>Leishmania infantum</em> in Spain, occurring in both continental and insular regions. This study investigates the genetic structure of <em>P. perniciosus</em> ...
Green cities and the risk for vector-borne disease transmission for humans and animals: a scoping review
Greening cities is a nature-based strategy for sustainable urban development that integrates natural elements</p><p>like plants or water bodies, to mitigate climate change impacts and enhance human well-being. However, ...
Is leishmaniosis widespread in Spain?. First data on canine leishmaniosis in the province of Lleida, Catalonia, norheast Spain
Canine leishmaniasis (CanL) is a widespread disease present in 42 countries. It is considered of epidemiological importance because of its role as a reservoir of human leishmaniasis. Knowledge of the real distribution of ...
Wild mammals as potential silent reservoirs of Leishmania infantum in a Mediterranean area
A molecular survey of wild mammals was performed to assess their potential as reservoirs of L. infantum. A total of 156 specimens of wild mammalian fauna were obtained for analysis from areas in Catalonia with a reported ...
Quality assurance of serologic testing for Chagas disease in a primary care setting of rural Paraguay
The diagnosis of Chagas disease mostly relies on the use of multiple serologic tests that are often unavailable in many of the remote settings where the disease is highly prevalent. In the Teniente Irala Fernández Municipality, ...
Detection of <em>Ichthyophthirius multifiliis </em>(Ichthyophthiriidae) in two wildamphibian species.
Emerging infectious diseases are one of the main threats to global amphibian populations. Frogs and salamanders are already affected by various pathogens, including ranaviruses, <em>Batrachochytrium dendrobatidis</em>, ...
Holobiont-based genetic analysis reveals new plant and microbial markers for resistance against a root rot pathogen complex in pea
Background The pea root rot complex is caused by various soil-borne pathogens that likely reinforce each other, influencing the composition of the root microbiome and leading to significant yield reductions. Previous studies ...
Crop genotype modulates root rot resistance-associated microbial community composition and abundance of key taxa
Background: Plants are constantly challenged by pathogens, which can cause substantial yield losses. The aggressiveness of and damage by pathogens depends on the host-associated microbiome, which might be shaped by plant ...
Inflammatory responses associated with acute coronary syndrome up-regulate IRAK-M and induce endotoxin tolerance in circulating monocytes
Acute coronary syndrome (ACS) groups different cardiac diseases whose development is associated with inflammation. Here we have analyzed the levels of inflammatory cytokines and of members of the TLR/IRAK pathway including ...
The Pentacyclic Triterpenes α, β-amyrins: A Review of Sources and Biological Activities
Pentacyclic triterpenes are ubiquitously distributed throughout the plant kingdom, in a free form as aglycones or in combined forms, and have long been known to have a number of biological effects. The compounds alpha-amyrin ...
Influència de la giberelina i la quinetina sobre la germinació i metabolisme nitrogenat de Nicotiana rustica
The seeds treated with. gibberellin 10-6 M have RNA and protein levels higher than those of control seeds and have a greater germinative capacity. The kinetin 10-6 M increases the RNA levels mainly of the poly A+RNA fraction ...
Green Catanionic Gemini Surfactant-Lichenysin Mixture: Improved Surface, Antimicrobial, and Physiological Properties
Catanionic surfactant mixtures form a wide variety of organized assemblies and aggregates with improved physicochemical and biological properties. The green catanionic mixture (NN omega)-N-alpha-Bis(N(alpha)caproylarginine) ...

Karyological study of some E Iberian threatened plants
In the framework of cytogenetic studies of rare and threatened plant species of the Catalan Countries and surrounding territories, a karyological study of some taxa - three populations of Delphinium bolosii and the only ...
Nitric oxide induces SOCS-1 expression in human monocytes in a TNFalpha-dependent manner
In contrast to the thoroughly characterized mechanisms of positive regulation within cytokine signaling pathways, our knowledge of negative feedback loops is comparatively sparse. We and others have previously reported ...
Intraindividual Variation in Nuclear DNA Content in Durvillaea Antarctica (Chamisso) Hariot, Macrocystis pyrifera (Linnaeus) C. Agardh and Lessonia spicata (Suhr) Santelices (Phaeophyceae)
Macrocystis C. Agardh, Durvillaea Bory and Lessonia Bory are three brown seaweeds genera of commercial importance for Chilean fishermen. Macrocystis pyrifera (Linnaeus) C. Agardh (Laminariales, Laminariaceae) is one of the ...
Tailoring tobacco hairy root metabolism for the production of stilbenes
Tobacco hairy root (HR) cultures, which have been widely used for the heterologous production of target compounds, have an innate capacity to bioconvert exogenous t-resveratrol (t-R) into t-piceatannol (t-Pn) and t-pterostilbene ...
Genetic structure and seed germination in Portuguese populations of Cheirolophus uliginosus (Asteraceae): Implications for conservation strategies
Cheirolophus uliginosus is a threatened species, endemic to the Atlantic coast of the Iberian Peninsula, where it occupies a few restricted localities. In our study we analysed the patterns of cpDNA haplotypes variation ...
