Association of the ADRB2 rs1042714 variant with retinopathy of prematurity highlights the importance of the renin-angiotensin-aldosterone system

Abstract Retinopathy of prematurity (ROP) remains a leading cause of childhood blindness globally. The clinical progression of ROP exhibits notable similarities to infantile hemangioma (IH), suggesting shared risk factors and underlying mechanisms. This study aimed to investigate the influence of variants in genes postulated for IH—specifically, anthrax toxin receptor 1 ( ANTXR1 ), beta-2-adrenergic receptor ( ADRB2 ), Fms-related tyrosine kinase 4 receptor ( FLT4 ), kinase insert domain receptor ( KDR ), and insulin-like growth factor 1 receptor ( IGF1R )—on the development and severity of ROP. In our analysis of 210 infants born at a gestational age of less than 33 weeks, we identified the ADRB2 rs1042714G variant allele as a significant risk factor for ROP, particularly its proliferative form. This risk was exacerbated by interactions with factors associated with neonatal respiratory failure, such as surfactant therapy, postnatal resuscitation, and mechanical ventilation, as well as the angiotensin II type 1 receptor variant ( AGTR1 rs5186A > C), previously linked to ROP risk in meta-analyses. Moreover, STRING protein-protein interaction analysis revealed that the ADRB2 protein interacts directly with a component of the vascular endothelial growth factor signaling pathway. These findings highlight potential pharmacological targets for ROP interventions, emphasizing the importance of understanding genetic contributions to this complex condition.

Assessing geometric microliths as cultural markers through an analysis of shape variation and projectile performance

Abstract European geometric microlith shape variation is often used as a marker of cultural differences between groups of Mesolithic hunter gatherers and/or Neolithic farmers. Indeed, the 2D plan-view shape of these lithics is known to vary in spatially and temporally systematic ways between archaeological sites. Such differences are well evidenced in the Iberian Peninsula between the 9th and 8th millennia BP. Here we test an alternative hypothesis for the structured variation observed in geometric microliths: whether their plan-view shape significantly impacts the force, energy and displacement experienced when they are used as projectile tips. If functional differences between groups help to explain the shape variation observed in the archaeological record, then any role for cultural (non-functional social) explanations is potentially reduced. We undertook controlled static penetration tests using an Instron materials tester and an assemblage of replicated Iberian geometric microliths hafted to standardised wooden shafts. Results indicate that the maximum force required, energy used, and displacement at maximum force experienced by these hafted geometric microliths when used as projectile armatures is not significantly influenced by their 2D plan-view shape. Rather, gross form attributes such as maximum thickness, distance from the tip of the microlith to the start of the shaft, and the maximum width of the hafting substrate/adhesive are the greatest determinants of penetration ease, along with the positioning of the microlith when hafted. Our data therefore supports past research that proposes a cultural role for geometric microlithic shape variation in the European Mesolithic and Early Neolithic. Moreover, it highlights the functional importance of maintaining relatively thin microblades during microlith production, along with taking care to minimise the size of hafting components and the necessity to haft them in the most efficient way.

Dopamine fast determination in pharmaceutical products using disposable printed electrodes modified with bimetal oxides carbon nanotubes nanocomposite

Abstract Dopamine is an essential neurotransmitter involved in the regulation of our pleasure, motivation, and other biological functions. Thus, tracking and monitoring the biological dopamine level is crucial for the rapid and effective treatment as well as for the diagnosis of the neurodegenerative and neurological disorders. Nanostructured electrochemical systems are tested and validated as promising methods for dopamine detection. In this study, carbon nanotube-anchored bimetallic manganese/copper bi-oxides nanocomposite-modified screen-printed carbon electrodes (Mn/Cu oxides @CNTs-SPCEs) were exploited for the electrocatalytic oxidation and direct determination of dopamine. From the morphological analysis, the particle size of the bimetallic oxides spherical nanoparticles was ranged from 9.0 to 45 nm, while the electrocatalytic activity of nanocomposite towards dopamine oxidation was examined by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) to demonstrate the acquired high sensitivity and selectivity. The optimized DPV assay provided a wide linear dynamic range of dopamine concentrations (from 0.001 to 140 µM), and a low detection limit of 0.3 nM. Eventually, the newly modified electrochemical method was applied for dopamine detection in pharmaceutical products with high accuracy.
