How Habitat Simplification Shapes the Morphological Characteristics of Ant Assemblages (Hymenoptera: Formicidae) in Different Biogeographical Contexts.

Human-driven changes in land cover and use can significantly impact species ants community structures, often leading to a decline in taxonomic diversity or species homogenization. Ant morphology, used as a proxy for ecological function, offers a valuable framework for understanding the effects of anthropogenic disturbances on ant diversity. This study explored the morphological diversity of ant assemblages in agricultural ecosystems and secondary forests in Italy and the Brazilian Amazon, analyzing how these communities are structured and adapted to different environments.

Predictors of study dropout in cognitive-behavioural therapy with a trauma focus for post-traumatic stress disorder in adults: An individual participant data meta-analysis.

Background: Available empirical evidence on participant-level factors associated with dropout from psychotherapies for post-traumatic stress disorder (PTSD) is both limited and inconclusive. More comprehensive understanding of the various factors that contribute to study dropout from cognitive-behavioural therapy with a trauma focus (CBT-TF) is crucial for enhancing treatment outcomes.

Objective: Using an individual participant data meta-analysis (IPD-MA) design, we examined participant-level predictors of study dropout from CBT-TF interventions for PTSD.

Fight or flight alternative mating tactics may explain the iconic male polymorphism of the European stag beetle.

The existence of different male morphologies within a single species is associated with alternative mating tactics across different animal groups, offering textbook examples of evolutionary biology. The European stag beetle Lucanus cervus is a flagship species which has long fascinated naturalists for its charismatic appearance and behavior, with males possessing large mandibles used in ritualized ground fights for females. Males are polymorphic, with larger males possessing disproportionately larger mandibles and being better fighters, while smaller males require less food to develop and may have better chances to escape predation.

Neighbors sharing pathogens: the intricate relationship between Apis mellifera and ants (Hymenoptera: Formicidae) nesting in hives.

Ants are ubiquitous and eusocial insects that exhibit frequent physical contact among colony members, thereby increasing their susceptibility to diseases. Some species are often found in beehives and in their surroundings, where they exploit the food resources of honey bees. This intricate relationship may facilitate the interspecific transmission of honey bee pathogens to ants, although ants themselves may contribute to spillback phenomena.

The therapeutic potential of plant extracts is garnering increasing interest, and this study aimed to demonstrate promising outcomes from an extract obtained from an underutilized plant waste. , an invasive macroalga found in the Orbetello Lagoon, thrives in eutrophic conditions, forming persistent mats covering approximately 400 hectares since 2005.

Associations between trauma exposure and irritability within the family unit: a network approach.

Background: Pediatric irritability is a pervasive psychiatric symptom, yet its etiology remains elusive. While trauma exposure may contribute to the development of irritability, empirical research is limited. This study examined the prevalence of irritability among trauma-exposed children, identified factors that differentiate trauma-exposed children with and without irritability, and employed a network analysis to uncover associations between irritability and trauma exposure in the family unit.

Caregiver Report of Children's Exposure to Adverse Life Events: Concordance Between Questionnaire and Interview Approaches.

Assessment practices for measuring adverse life events (ALEs) are often characterized by considerable variability, which is associated with inconsistency and reproducibility issues when conducting research on children with ALE exposure. One aspect of assessment variability for caregiver report of children's ALE history that has received minimal attention is assessment format. To address this issue, the current study evaluated concordance between two main ALE assessment formats: interviews and questionnaires.

Coxa pedis: can calcaneal pronation angle be considered a predictive sign of medial plantar arch overload?

Purpose: To assess whether a correlation between the calcaneal pronation angle and the presence of internal plantar arch overload signs (such as upper-medial spring ligament lesion, posterior tibial tendon tenosynovitis, etc.) could lead to a better understanding of coxa pedis pathology.

Material And Methods: One hundred ankle MRIs of consecutive patients were retrospectively reviewed measuring the calcaneal pronation angle and either the presence or absence of internal plantar arch overload signs.

Trail pheromone identification in the ant Crematogaster scutellaris.

In this work, we identified the trail pheromone of the ant Crematogaster scutellaris. We combined gas chromatography-mass spectrometry analysis of extracts from the hind tibia, the location of the respective glands, with automated trail following assays. The study found tridecan-2-ol to be the strongest discriminator between hind tibia and other body part extracts.

Harms and Benefits Inventory (HBI): initial validation of a novel assessment of perceived harms and benefits of firearm policies and practices.

Introduction: Understanding gun owners' perceptions of potential firearm policies' harms and benefits is critical to successful policy development and implementation. We used national survey data to develop and validate a novel instrument, the Harms and Benefits Inventory (HBI), for policy-makers and advocates to better consider the citizen perspective.

Method: We conducted a nationally representative survey of American gun owners and non-owners (N=2007) using the Social Science Research Solutions probability panel.

Effectiveness of bismuth subgallate for preventing bleeding following adenotonsillectomy: A multicentre study.

Background: Tonsillectomy and adenotonsillectomy are surgical procedures routinely performed worldwide, with various complications, including postoperative bleeding (PTH). Among haemostatic agents, bismuth subgallate (BS) has been employed in the past decades, but its use is controversial in children.

Objective: This retrospective, multicentre study aims to evaluate the effectiveness and safety of BS in preventing PTH following tonsillectomy and adenotonsillectomy.

Innovative Experimental Ultrasound and US-Related Techniques Using the Murine Model in Pancreatic Ductal Adenocarcinoma: A Systematic Review.

Pancreatic ductal adenocarcinoma (PDAC) is a cancer with one of the highest mortality rates in the world. Several studies have been conductedusing preclinical experiments in mice to find new therapeutic strategies. Experimental ultrasound, in expert hands, is a safe, multifaceted, and relatively not-expensive device that helps researchers in several ways.

The Epidemic-Pandemic Impacts Inventory (EPII): A multisample study examining pandemic-related experiences and their relation to mental health.

The Epidemic-Pandemic Impacts Inventory (EPII) was developed to assess pandemic-related adverse and positive experiences across several key domains, including work/employment, home life, isolation, and quarantine. Several studies have associated EPII-assessed pandemic-related experiences with a wide range of psychosocial factors, most commonly depressive and anxiety symptoms. The present study investigated the degree to which specific types of COVID-19 pandemic-related experiences may be associated with anxiety and depression risk, capitalizing on two large, independent samples with marked differences in sociodemographic characteristics.

Fight and rescue or give up and flee? Behavioural responses of different ant species tending the mutualist walnut aphid to native and exotic lady beetles.

Mutualism between ants and honeydew-producing hemipterans is a highly successful evolutionary innovation that attains the status of ecological keystone across many terrestrial ecosystems, involving a multitude of actors through direct or cascading effects. In these relationships, ants often protect their hemipteran partners against their arthropod natural enemies, sometimes interfering with the biological control of pest species. However, the dynamics of these interactions are highly variable based on the specific identity of all the actors involved, and baseline data remain scarce.

SUFU promotes GLI activity in a Hedgehog-independent manner in pancreatic cancer.

Aberrant activation of the Hedgehog (Hh) signaling pathway, through which the GLI family of transcription factors (TF) is stimulated, is commonly observed in cancer cells. One well-established mechanism of this increased activity is through the inactivation of Suppressor of Fused (SUFU), a negative regulator of the Hh pathway. Relief from negative regulation by SUFU facilitates GLI activity and induction of target gene expression.

Reducing Family Violence Through Child Welfare Intervention: A Propensity Score-Matched Study of Fathers for Change.

Intimate partner violence (IPV) is prevalent, costly, and detrimental to children's health and development. It often co-occurs with child abuse and neglect. Most children referred to child protective services (CPS) have witnessed IPV and are at increased risk for subsequent exposure, as well as repeat maltreatment.

Cumulative stress, PTSD, and emotion dysregulation during pregnancy and epigenetic age acceleration in Hispanic mothers and their newborn infants.

Pregnancy can exacerbate or prompt the onset of stress-related disorders, such as post-traumatic stress disorder (PTSD). PTSD is associated with heightened stress responsivity and emotional dysregulation, as well as increased risk of chronic disorders and mortality. Further, maternal PTSD is associated with gestational epigenetic age acceleration in newborns, implicating the prenatal period as a developmental time period for the transmission of effects across generations.

Missouri Citizen Perceptions: Giving Second Amendment Preservation Legislation a Second Look.

In June 2021, Missouri passed the "Second Amendment Preservation Act" (SAPA). Though SAPA passed easily and had gubernatorial support, many Missouri law enforcement agencies, including the Missouri Sheriff's Association, oppose it. Missing from this policy conversation, and deserving of analysis, is the voice of Missouri citizens.

A Comparison of Small Rodent Assemblages after a 20 Year Interval in the Alps.

Human-induced environmental alterations in the Alps may importantly affect small mammal species, but evidence in this sense is limited. We live-trapped small rodents in the Central-Eastern Italian Alps in three close-by habitat types (rocky scree, alpine grassland, and heath) at 2100 m a.s.

Pharmacological Chaperones and Protein Conformational Diseases: Approaches of Computational Structural Biology.

Whenever a protein fails to fold into its native structure, a profound detrimental effect is likely to occur, and a disease is often developed. Protein conformational disorders arise when proteins adopt abnormal conformations due to a pathological gene variant that turns into gain/loss of function or improper localization/degradation. Pharmacological chaperones are small molecules restoring the correct folding of a protein suitable for treating conformational diseases.
