For decades, welfare scientists have focused on investigating and mitigating the abnormal behaviors-including repetitive stereotypic behaviors and abnormal stances/postures-displayed by chimpanzees residing in professionally managed settings. In an effort to design feasible and practical welfare assessments, researchers often pool abnormal behaviors into subcategories. However, this approach can result in the creation of heterogeneous subcategories comprised of behaviors that do not statistically co-occur.

Article Synopsis
  • In early-stage triple-negative breast cancer (TNBC), high glucocorticoid receptor (GR) expression is linked to poor outcomes, potentially due to an immunosuppressed tumor microenvironment.
  • A study of 47 patients showed that high GR expression correlated with increased levels of immunosuppressive FOXP3+ regulatory T cells and BATF3+ immune cells, but not significantly with CD8+ T cell infiltration.
  • The findings suggest that high GR expression may contribute to a more immunosuppressed state in TNBC, which could explain worse prognoses for patients with GR-positive tumors.

Article Synopsis
  • The study focuses on a rare superficial variant of deep penetrating/plexiform melanocytomas/nevi (DPN) that includes a junctional component, complicating diagnosis.
  • It includes 11 cases from 10 patients (5 men and 5 women) aged 27 to 78, with lesions found in various locations, and most cases being associated with a conventional nevus.
  • Immunohistochemical analysis shows strong nuclear beta-catenin and LEF1 staining in all DPN cases, while conventional nevi displayed the opposite pattern, highlighting the need for careful differentiation to avoid misdiagnosis as melanoma.

Ovarian germ cell tumors (GCT) account for 2% to 3% of malignant ovarian neoplasms in Western countries and typically occur within the first 2 decades. When presenting later in life, GCTs may be associated with epithelial malignancies. In these circumstances, it has been theorized that these tumors may originate from a somatic, rather than germ cell origin, especially in the postmenopausal setting; however, the true derivation is not fully understood.

Among mammals, the order Primates is exceptional in having a high taxonomic richness in which the taxa are arboreal, semiterrestrial, or terrestrial. Although habitual terrestriality is pervasive among the apes and African and Asian monkeys (catarrhines), it is largely absent among monkeys of the Americas (platyrrhines), as well as galagos, lemurs, and lorises (strepsirrhines), which are mostly arboreal. Numerous ecological drivers and species-specific factors are suggested to set the conditions for an evolutionary shift from arboreality to terrestriality, and current environmental conditions may provide analogous scenarios to those transitional periods.

Seasonal windows of opportunity are intervals within a year that provide improved prospects for growth, survival, or reproduction. However, few studies have sufficient temporal resolution to examine how multiple factors combine to constrain the seasonal timing and extent of developmental opportunities. Here, we document seasonal changes in milkweed ()-monarch () interactions with high resolution throughout the last three breeding seasons prior to a precipitous single-year decline in the western monarch population.

Article Synopsis
  • - Metabolic and ionic changes during ischaemia make the heart vulnerable to damage from reperfusion, and these effects differ between immature and adult hearts; hence, adult cardioprotective strategies should be tested on immature hearts.
  • - Researchers found that activating protein kinase A (PKA) and exchange protein activated by cAMP (Epac) simultaneously provides significant protection against injury in adult hearts and aimed to see how effective this intervention is in immature hearts.
  • - The study showed that immature hearts are less prone to ischaemia/reperfusion (I/R) injury, likely due to reduced mitochondrial permeability transition pore (MPTP) opening, and that simultaneous PKA and Epac activation further enhances this protective effect. *

Foraging on flowers in low light at dusk and dawn comes at an additional cost for insect pollinators with diurnal vision. Nevertheless, some species are known to be frequently active at these times. To explore how early and under which light levels colonies of bumblebees, initiate their foraging activity, we tracked foragers of different body sizes using RFID over 5 consecutive days during warm periods of the flowering season.

Gene replacement approaches are leading to a revolution in the treatment of previously debilitating monogenic neurological conditions. However, the application of gene therapy to complex polygenic conditions has been limited. Down-regulation or dysfunction of receptor expression in the disease state or in the presence of excess ligand has been shown to compromise therapeutic efficacy.

Background: A wide range of therapeutic regimens, including single-inhaler triple therapies (SITTs), are now available for the maintenance treatment of chronic obstructive pulmonary disease (COPD). Thus, an improved understanding of patient preferences may be valuable to inform physician prescribing decisions. This study was performed to assess the factors considered by patients when making decisions about their COPD treatments using qualitative techniques.

Parkinson's disease (PD) is an α-synucleinopathy characterized by the progressive loss of specific neuronal populations. Here, we develop a novel approach to transvascularly deliver proteins of complex quaternary structures, including α-synuclein preformed fibrils (pff). We show that a single systemic administration of α-synuclein pff triggers pathological transformation of endogenous α-synuclein in non-transgenic rats, which leads to neurodegeneration in discrete brain regions.

Games derived from experimental economics can be used to directly compare decision-making behavior across primate species, including humans. For example, the use of coordination games, such as the Assurance game, has shown that a variety of primate species can coordinate; however, the mechanism by which they do so appears to differ across species. Recently, these games have been extended to explore anti-coordination and cooperation in monkeys, with evidence that they play the Nash equilibria in sequential games in these other contexts.
