Dropping out of higher education: Analysis of variables that characterise students who interrupt their studies.

One of the persistent problems faced by the university education system is the dropout rate. The main aim of this research was to identify the profile characteristics of those students who drop out of their studies, seeking in-depth knowledge of the reality behind the issue. The responses to a questionnaire of 149,837 students from three Spanish universities (La Laguna, Zaragoza and Huelva) who had dropped out of their undergraduate studies were analysed.

: a training program to increase evidence-based science communication and literacy for Hispanic high school and undergraduate students.

Science misinformation represents a significant challenge for the scientific community. Hispanic communities are particularly vulnerable due to language barriers and the lack of accessible information in Spanish. We identified that a key step toward enhancing the accessibility of information for non-native English-speaking communities involves imparting science communication education and training to Hispanic youth.

Pharmacokinetics of fluralaner as a systemic drug to control infestations of the common bed bug, Cimex lectularius, in poultry facilities.

Background: Bed bug infestations are re-emerging in the poultry industry throughout the USA. Although the impacts of bed bugs on birds' health and welfare are poorly understood, adverse outcomes are expected, including stress, anemia, infections and lower production rates. Worker welfare is also an important consideration in commercial poultry farms.

Spatial distribution of histamine in bed bug-infested homes.

Histamine is a component of the bed bug aggregation pheromone. It was recently identified as an environmental contaminant in homes with active bed bug infestations, posing a potential health risk to humans via skin contact or inhalation. It remains unclear how histamine is distributed in homes and if histamine can become airborne.

Status of Ecosystem Services in Abandoned Mining Areas in the Iberian Peninsula: Management Proposal.

An abandoned sphalerite mining area in the southwest (SW) of the Iberian Peninsula was studied to evaluate the impact that the presence of metal(loid)s has on soil and ecosystem health. Five zones were delimited: sludge, dump, scrubland, riparian zone, and dehesa. Critical total levels of lead (Pb), zinc (Zn), thallium (Tl), and chromium (Cr), well above the limit indicative of toxicity problems, were found in the areas close to the sources of contamination.

Threats of metal mining on ecosystem services. Conservation proposals.

We have studied, in a protected area with intense hunting activity, the consequences of the abandonment of facilities and tailings of a metal mine. The area studied has the peculiarity of having a steep slope and containing a water reservoir for irrigation and human consumption. Soil, sludge, vegetation, and water samples were analyzed, in which many metal(loid)s exceeded the generic reference levels (NGR) established for the health of the ecosystem.

Multiple Mechanisms Confer Fipronil Resistance in the German Cockroach: Enhanced Detoxification and Rdl Mutation.

Populations of Blattella germanica (L.) (German cockroach) have been documented worldwide to be resistant to a wide variety of insecticides with multiple modes of action. The phenylpyrazole insecticide fipronil has been used extensively to control German cockroach populations, exclusively in baits, yet the highest reported fipronil resistance is 38-fold in a single population.

Analysis of the Effects of Melanin Depigmentation on Immunohistochemical Staining.

Heavily pigmented lesions are difficult to evaluate histologically, as melanin obscures cellular details. Several classic laboratory techniques aim to clear melanin and allow evaluation. Most of them are old and appeared before immunohistochemistry (IHC) use.

Resistance to Fipronil in the Common Bed Bug (Hemiptera: Cimicidae).

Cimex lectularius L. populations have been documented worldwide to be resistant to pyrethroids and neonicotinoids, insecticides that have been widely used to control bed bugs. There is an urgent need to discover new active ingredients with different modes of action to control bed bug populations.

Behavioral Responses of the Common Bed Bug to Essential Oil Constituents.

Botanical-derived pesticides have arisen as an attractive alternative to synthetic insecticides to effectively manage infestations of bed bugs ( L.). While information on contact, residual, and fumigant toxicity of plant-essential oils against bed bugs have been recently published, there is a gap of information regarding the repellent activity of these products and their constituents.

, a Gene Potentially Implicated in Familial Colorectal Cancer Type X.

Familial colorectal cancer Type X (FCCTX) comprises a heterogeneous group of families with an increased risk of developing colorectal cancer and other related tumors, but with mismatch repair-proficient, microsatellite-stable (MSS) tumors. Unfortunately, the genetic basis underlying their cancer predisposition remains unknown. Although pathogenic germline variants in increase the risk of developing hereditary ovarian cancer, the involvement of in hereditary colorectal cancer is still not well known.

Cytoplasmic Increase in Hsp70 Protein: A Potential New Biomarker of Early Infiltration of Cutaneous Squamous Cell Carcinoma Arising from Actinic Keratosis.

Background: Cutaneous squamous skin cell carcinoma (SCC) is the second most frequent type of non-melanoma skin cancer and is the second leading cause of death by skin cancer in Caucasian populations. However, at present it is difficult to predict patients with poor SCC prognosis.

Objective: To identify proteins with expression levels that could predict SCC infiltration in SCC arising from actinic keratosis (SCC-AK).

Effect of Synergists on Deltamethrin Resistance in the Common Bed Bug (Hemiptera: Cimicidae).

The common bed bug, Cimex lectularius L. (Hemiptera: Cimicidae), is an obligate hematophagous insect that has resurged worldwide since the early 2000s. Bed bug control is largely based on the widespread, intensive application of pyrethroid-based insecticide formulations, resulting in the emergence of insecticide-resistant bed bug populations.

Low-level light-assisted photodynamic therapy using a wearable cap-like device for the treatment of actinic keratosis of the scalp.

Background: Daylight photodynamic therapy (dlPDT) is a painless and increasingly cost-effective treatment for actinic keratosis (AK). New protocols avoid incubation, minimizing pain and adverse events. However, it is time-consuming and dependent on specific weather conditions.
