The high prevalence of allergic diseases reached over the last years is attributed to the complex interplay of genetic factors, lifestyle changes, and environmental exposome. Allergen-specific immunotherapy (AIT) is the single therapeutic strategy for allergic diseases with the potential capacity to modify the course of the disease. Our knowledge of the mechanisms involved in allergy and successful AIT has significantly improved.

The global impact of anticoagulant rodenticides (ARs) on non-target species is well-recognized. Birds of prey, as apex predators, are highly vulnerable to AR exposure and are widely used as biomonitors for priority pollutants in Europe. This study investigates differential SGAR exposure in raptors from insular versus continental regions, hypothesizing greater exposure in insular areas due to ecological factors like reduced prey diversity, intensive rodenticide use, and resistant rodent populations.

Trained immunity has emerged as a new concept in immunology that is associated with the memory of innate immune cells and linked to specific metabolic and epigenetic reprogramming of these cells. Trained immunity may confer nonspecific and sustained protection against a broad range of pathogens, and recent findings show that it might also be involved in allergy mechanisms. Some conventional vaccines have demonstrated trained immunity induction as the mechanism underlying their heterologous protection.

We construct new stabilizer quantum error-correcting codes from generalized monomial-Cartesian codes. Our construction uses an explicitly defined twist vector, and we present formulas for the minimum distance and dimension. Generalized monomial-Cartesian codes arise from polynomials in variables.

Background: Allergy represents a major health problem of increasing prevalence worldwide with a high socioeconomic impact. Our knowledge on the molecular mechanisms underlying allergic diseases and their treatments has significantly improved over the last years. The generation of allergen-specific regulatory T cells (Tregs) is crucial in the induction of healthy immune responses to allergens, preventing the development and worsening of allergic diseases.

It is well known that rodenticides are widely used, and there are multiple routes by which they can reach non-target wildlife species. Specifically, in the Canary Islands, a high and concerning incidence of these compounds has been reported. However, in this scenario, reptiles remain one of the least studied taxa, despite their potential suitability as indicators of the food chain and environmental pollution has been noted on several occasions.

Article Synopsis
  • * A study analyzed liver samples from 360 euthanized kingsnakes to detect 10 different ARs, finding that 90% tested positive, primarily for brodifacoum, and showed a correlation between the snakes' size and geographic location with AR concentration.
  • * The study suggests that California kingsnakes could serve as sentinel species for monitoring ARs in the ecosystem due to similarities in AR types and prevalence with local raptors, although more

Article Synopsis
  • - Functional T regulatory cells (Tregs) hinder anticancer immunity and play a significant role in tumor growth by developing in response to the tumor's environment.
  • - Researchers identified a tumor-derived carbohydrate called A10 (Ca10), which enhances glycolysis and promotes Treg development through various mechanisms involving metabolic changes and inflammatory signals.
  • - The study shows that higher levels of Ca10 in the serum correlate with tumor size and Treg counts in mice, and similar elevated levels of a human counterpart (Ca10H) are found in cancer patients, especially those with metastatic disease, suggesting new avenues for cancer therapies.

This study assesses the impact of second-generation anticoagulant rodenticides (SGARs) on the common kestrel (Falco tinnunculus canariensis) in Tenerife, Canary Islands. The analysis of 390 liver samples over 19 years using HPLC-MS/MS showed that 93.1 % of kestrels were exposed to SGARs in this island.

Introduction: Chronic or uncontrolled activation of myeloid cells including monocytes, macrophages and dendritic cells (DCs) is a hallmark of immune-mediated inflammatory disorders. There is an urgent need for the development of novel drugs with the capacity to impair innate immune cell overactivation under inflammatory conditions. Compelling evidence pointed out cannabinoids as potential therapeutic tools with anti-inflammatory and immunomodulatory capacity.

Purpose Of Review: Allergic diseases represent a major health problem of increasing prevalence worldwide. In allergy, dendritic cells (DCs) contribute to both the pathophysiology and the induction of healthy immune responses to the allergens. Different studies have reported that some common allergens contain glycans in their structure.

Introduction: Recurrent urinary tract infections (RUTIs) and recurrent vulvovaginal candidiasis (RVVCs) represent major healthcare problems all over the world. Antibiotics and antifungals are widely used for such infectious diseases, which is linked with microbial resistances and microbiota deleterious effects. The development of novel approaches for genitourinary tract infections (GUTIs) such as trained immunity-based vaccines (TIbV) is therefore highly required.

Article Synopsis
  • Innate immune cells undergo lasting metabolic and epigenetic changes after exposure to specific stimuli, enhancing their responses to pathogens in a process known as trained immunity.
  • Trained immunity-based vaccines (TIbV) can induce innate immune memory, potentially providing broader protection against various pathogens, yet their role in chronic allergic diseases remains unclear.
  • Recent studies indicate that environmental factors can cause innate immune cells to adopt pro-inflammatory roles in allergies, while certain vaccines may reprogram these cells to promote tolerance, suggesting new strategies for allergy prevention and treatment.

Implementation of the Global Sulphur Cap (GSC), in January 2020, boosted scrubber installation in vessels to fulfill the new air emission limitations. This increase in scrubbers' use has intensified concern about its environmental performance. Even though achievement of GSC requirements through this mitigation system has been widely proven, the impact of wash water discharge on the marine environment remains under discussion.

  • Animal poisoning poses a significant threat to wildlife, particularly in the Canary Islands, where the risk is higher than in other parts of Europe.
  • A study from 2014 to 2021 analyzed 961 animals and 84 baits, revealing that 251 animals and 61 baits were poisoned, with carbofuran being the most common poison used.
  • The introduction of canine patrols has improved the detection of poisoned animals, with higher rates of poison positivity found in rural areas and regions with intensive agricultural and livestock activities.

Recurrent urinary tract infections (RUTIs) and recurrent vulvovaginal candidiasis (RVVCs) represent major healthcare problems with high socio-economic impact worldwide. Antibiotic and antifungal prophylaxis remain the gold standard treatments for RUTIs and RVVCs, contributing to the massive rise of antimicrobial resistance, microbiota alterations and co-infections. Therefore, the development of novel vaccine strategies for these infections are sorely needed.

Although entrepreneurial intention has been widely studied using cognitive models, we still lack entrepreneurial vocation and, therefore, lack disruptive innovations. Entrepreneurship scholars have some understanding of the reasons underlying this weakness, although there is much room for improvement in our learning concerning how to promote entrepreneurship among university students, especially in the transformed context of digital technologies. This paper focuses on the early stages of start-up, and in particular seeks to evaluate what role social and psychological factors play in the development of entrepreneurial intentions.

β-phenylethylamine and tryptamine are biogenic amines (BA) often found in foods. In general, BA are assumed to be toxic and their accumulation in food is not recommended. However, present knowledge regarding the toxicity of β-phenylethylamine and tryptamine is limited; more information is needed if qualitative and quantitative risk assessments of foods are to be successfully conducted.
