Article Abstract
Objective assessment of coagulation in birds is difficult, and traditional methods of measuring prothrombin time (PT) and activated partial thromboplastin time (aPTT) with the use of mammalian reagents have not been validated in birds. Avian-specific reagents must be prepared from brain extract and are not practical for clinical use. The objective of this investigation was to determine whether the InSight qLabs point-of-care analyzer (Micropoint Biotechnologies Inc, Guangdong, China) could measure PT and aPTT in Hispaniolan Amazon parrots () in native and citrated whole blood, and whether the values obtained correlated with clinical appearance and basic hematologic and biochemical parameters from the bird. The qLabs analyzer was able to measure aPTT reliably, but not PT. Activated partial thromboplastin time of citrated blood was significantly different from the aPTT measured from native whole blood ( < 0.001). On the basis of this study, the qLabs machine may be used to measure aPTT, but clinical application between avian species requires further research.

Ni-Fe (oxy)hydroxides are among the most active oxygen evolution reaction (OER) catalysts in alkaline media. However, achieving precise control over local asymmetric Fe-O-Ni active sites in Ni-Fe oxyhydroxides for key oxygenated intermediates' adsorption steric configuration regulation of the OER is still challenging. Herein, we report a two-step dealloying strategy to fabricate asymmetric Fe-O-Ni pair sites in the shell of NiOOH@FeOOH/NiOOH heterostructures from NiFe Prussian blue analogue (PBA) nanocubes, involving anion exchange and structure reconstruction.

Language learning and use relies on domain-specific, domain-general cognitive and sensory-motor functions. Using fMRI during story listening and behavioral tests, we investigated brain-behavior associations between linguistic and non-linguistic measures in individuals with varied multilingual experience and reading skills, including typical reading participants (TRs) and dyslexic readers (DRs). Partial Least Square Correlation revealed a main component linking cognitive, linguistic, and phonological measures to amodal/associative brain areas.

Purpose: Crohn's disease (CD) is characterized by enteric inflammation, often resulting in strictures and penetrating complications, which may alter patient management prior to the initiation of biologic therapy. Our aim is to assess the frequency of missed stricturing and internal penetrating complications in CD patients on computed tomography enterography (CTE) and magnetic resonance enterography (MRE) performed prior to anti-TNF therapy.
Methods: We retrospectively reviewed patients from two tertiary centers who underwent CTE\MRE within six months before starting anti-TNF therapy.

The Atlantification of the Arctic is driving a northward habitat shift of many cetaceans, including sperm whales (Physeter macrocephalus). As Arctic warming continues to decrease sea ice extent and contributes to the change in species distributions, it is crucial to study how the distribution patterns, habitat, and the demographic structure of sperm whale populations may continue to change. In this study, we assess the temporal presence of echolocating sperm whales on the continental slope southwest of the Svalbard archipelago and compare it with acoustic backscatter and temperature as a proxy for biomass.

Feline infectious peritonitis virus (FIPV) can cause an immune-mediated disease that is fatal to felines, but there is a lack of clinically effective protection conferred by vaccines. The methyltransferase (MTase) activity of the coronavirus nonstructural proteins nsp14 and nsp16 affects virulence, but there are no studies on the effect of nsp14 and nsp16 mutations affecting enzyme activity on the virulence of FIPV. In this study, we successfully rescued two mutant strains based on the previous infectious clone QS-79, named FIPV QS-79 dnsp14 and dnsp16, by mutating the MTase active sites of nsp14 (N415) and nsp16 (D129).
