Use of translational fusions to express functional Klebsiella oxytoca dinitrogenase reductase in plant mitochondriaNARA Subscribed
Engineering crop plants with the biological nitrogen fixation pathway is a longstanding goal of modern agriculture. Dinitrogenase reductase (NifH) is a critical component of the biological nitrogen fixation pathway, with multiple roles in metal cofactor assembly and catalysis. This enzyme must be folded correctly as a soluble homodimer and loaded with the [4Fe-4S] metallocluster for function. Previous studies have found that K...
Local drug delivery systems (LDDS) are a promising method to overcome challenges associated with chemotherapeutic treatment of brain tumours, namely poor blood-brain barrier penetration. Here we report a poly(ethyleneglycol)-poly(lactide)-poly(caprolactone)-poly(lactide)-poly(ethyleneglycol) based injectable hydrogel, PELCLE, loaded with Doxorubicin (Dox) and Olaparib (Ola) as an LDDS against glioblastoma (GBM), a primary mali...
Introduction Dietary exposure to melamine (MELA) adversely affects growth performance and intestinal health in Nile tilapia. This study evaluated the protective effects of Crataegus sinaica leaf extract (CSL) against MELA-induced toxicity. Methods In this study, a total of 240 fish (26.39 ± 0.22) were randomly assigned to four groups (60 fish/group; four replicates of 15 fish each). The control group received a basal diet, the...
Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...
Virulence arsenal of Acinetobacter baumannii: mechanisms driving persistence and resistanceNARA Subscribed
Acinetobacter baumannii is a Gram-negative opportunistic pathogen and a major cause of healthcare-associated infections, including ventilator-associated pneumonia, bacteraemia, meningitis, and urinary tract infections. Its persistence in hospital environments is due to its ability to survive desiccation, resist disinfectants, and colonize both biotic and abiotic surfaces. Virulence in A. baumannii is largely associated with st...
Diagnosing scaling bottlenecks in 10 community conservation initiatives in southern and eastern AfricaNARA Subscribed
Scaling area‐based conservation, including initiatives led or comanaged by Indigenous Peoples and local communities, is a flagship goal of the Kunming‐Montreal Global Biodiversity Framework. Conservationists often aspire to scale initiatives, but this is rarely achieved in practice. Identifying and addressing factors that limit initiative adoption (i.e., bottlenecks) could improve scaling strategies. We used insightsfrom 84 ex...
Bakanae disease of rice has emerged as a major threat in the rice‐growingregions of Eastern and Northeastern India. Under field conditions, Fusarium species associated with bakanae disease of rice exhibit a significant degree of variability. Characterizing the pathogen and its isolates is crucial for understanding this variability. This study aimed to assess the genetic diversity and virulence patterns among 88 Fusarium isolat...
Alzheimer’s disease (AD) disproportionately affects women and carriers of the apolipoprotein E ε4 allele (APOE4), yet little is known about how sex and APOE interact to influence white matter (WM) integrity during disease progression. We integrated diffusion MRI and matched blood transcriptomic data to investigate these interactions and their underlying biological mechanisms. WM microstructure was quantified using diffusion te...
