Abstract

Mitigating human-caused mortality for large carnivores is a pressing global challenge for wildlife conservation. However, mortality is almost exclusively studied at local (within-population) scales creating a mismatch between our understanding of risk and the spatial extent most relevant to conservation and management of wide-ranging species. Here, we quantified mortality for 590 radio-collared mountain lions statewide across their distribution in California to identify drivers of human-caused mortality and investigate whether human-caused mortality is additive or compensatory. Human-caused mortality, primarily from conflict management and vehicles, exceeded natural mortality despite mountain lions being protected from hunting. Our data indicate that human-caused mortality is additive to natural mortality as population-level survival decreased as a function of increasing human-caused mortality and natural mortality did not decrease with increased human-caused mortality. Mortality risk increased for mountain lions closer to rural development and decreased in areas with higher proportions of citizens voting to support environmental initiatives. Thus, the presence of human infrastructure and variation in the mindset of humans sharing landscapes with mountain lions appear to be primary drivers of risk. We show that human-caused mortality can reduce population-level survival of large carnivores across large spatial scales, even when they are protected from hunting.

Abstract

BACKGROUND: The Alberta Stroke Program Early CT Score (ASPECTS) is used to quantify the extent of injury to the brain following acute ischemic stroke (AIS) and to inform treatment decisions. The e-ASPECTS software uses artificial intelligence methods to automatically process non-contrast CT (NCCT) brain scans from patients with AIS affecting the middle cerebral artery (MCA) territory and generate an ASPECTS. This study aimed to evaluate the impact of e-ASPECTS (Brainomix, Oxford, UK) on the performance of US physicians compared to a consensus ground truth. METHODS: The study used a multi-reader, multi-case design. A total of 10 US board-certified physicians (neurologists and neuroradiologists) scored 54 NCCT brain scans of patients with AIS affecting the MCA territory. Each reader scored each scan on two occasions: once with and once without reference to the e-ASPECTS software, in random order. Agreement with a reference standard (expert consensus read with reference to follow-up imaging) was evaluated with and without software support. RESULTS: A comparison of the area under the curve (AUC) for each reader showed a significant improvement from 0.81 to 0.83 (p = 0.028) with the support of the e-ASPECTS tool. The agreement of reader ASPECTS scoring with the reference standard was improved with e-ASPECTS compared to unassisted reading of scans: Cohens kappa improved from 0.60 to 0.65, and the case-based weighted Kappa improved from 0.70 to 0.81. CONCLUSION: Decision support with the e-ASPECTS software significantly improves the accuracy of ASPECTS scoring, even by expert US neurologists and neuroradiologists.

Abstract

The development of simple, versatile strategies for the synthesis of gold nanoparticles (AuNPs) on semiconducting transition metal dichalcogenides (TMDC) layers is of increasing scientific and technological interest in photocatalysis, optical sensing, and optoelectronics sectors, but challenges exist on the nucleation and hybridization of AuNPs with the TMDC basal plane. At present, the widely used aqueous solution approaches suffer from poor dispersion of produced hybrids as well as from limited growth and coverage of the AuNPs on the TMDC semiconducting plane, since Au nanoclusters nucleate preferentially at the electron rich defect edges, which act as reducing agents and not on the defect free basal plane. Here, we report for the first time, the controlled synthesis of AuNPs on the basal plane of semiconducting molybdenum disulfide nanosheets (2H-MoS2 NSs) via a N,N-dimethylformamide (DMF)-based hot-injection synthesis route. This organic solvent-based synthesis route eliminates problems of poor dispersion of AuNPs@2H-MoS2 NS hybrids, whereas at the same time maintains the semiconducting crystalline quality of the pristine 2H-MoS2 NSs. In addition, the study establishes the important role of trisodium citrate, on enhancing the nucleation and improving the hybridization of AuNPs on 2H-MoS2 NSs as evidenced by the induced p-type doping. This organic solvent synthesis approach can be adopted for other hybrid systems opening the way for controlled hybridization of semiconducting layers with metal nanoparticles., Comment: corresponding author e-mail: p.papakonstantinou@ulster.ac.uk accepted at The Journal of Physical Chemistry C

47. Sensitive Chronocoulometric Detection of miRNA at Screen-printed Electrodes modified by Gold decorated MoS2 Nanosheets

Abstract

Here a new chronocoulometric sensor, based on semiconducting 2H MoS2 nanosheets decorated with a controlled density of monodispersed small gold nanoparticles, was fabricated via electrodeposition, for the highly sensitive detection of miRNA-21. The size and interparticle spacing of AuNPs was optimized by controlling nucleation and growth rates through tuning of deposition-potential and Au-precursor concentration and by getting simultaneous feedback from morphological and electrochemical activity studies. The sensing strategy, involved the selective immobilization of thiolated capture probe DNA (CP) at AuNPs and hybridization of CP to a part of miRNA target, whereas the remaining part of the target was complementary to a signaling non-labelled DNA sequence. Chronocoulometry provided precise quantification of nucleic acids at each step of the sensor assay by interrogating [Ru(NH3)6]3+ electrostatically bound to phosphate backbones of oligonucleotides. A detailed and systematic optimization study demonstrated that the thinnest and smallest MoS2 NSs improved the sensitivity of the AuNP@MoS2 sensor achieving an impressive detection limit of 100 aM, which is 2 orders of magnitude lower than that of bare Au electrode and also enhanced the DNA-miRNA hybridization efficiency by 25%. Such improved performance can be attributed to the controlled packing density of CPs achieved by their self -assembly on AuNPs, large interparticle density, small size and the intimate coupling between AuNPs and MoS2. Alongside the outstanding sensitivity, the sensor exhibited excellent selectivity down to femtomolar concentrations, for discriminating complementary miRNA-21 target in a complex system composed of different foreign targets including mismatched and non-complementary miRNA-155. These advantages make our sensor a promising contender in the point of care miRNA sensor family for medical diagnostics., Comment: Pagona Papakonstantinou corresponding author (p.papakonstantinou@ulster.ac.uk)
