Cerebral hypoperfusion, brain structural integrity, and cognitive impairment in older APOE4 carriersNARA Subscribed
Cerebral blood flow (CBF) deficits, cognitive decline, and brain structural changes have been reported in older adults with and without apolipoprotein E-e4 ( APOE4 )-related risk for dementia. However, it remains unclear whether brain structural changes mediate the effects of hypoperfusion on cognitive impairment in APOE4 carriers and non-carriers. We studied 166 (60–89 years) APOE4 carriers (ε3/ε4 or ε4/ε4) and APOE3 homozygo...
Management of the Colorado potato beetle ( Leptinotarsa decemlineata ) is reliant on conventional insecticides that can negatively affect non-target arthropods. Calantha™ (active ingredient: ledprona) is a sprayable double-stranded RNA biopesticide specific for L decemlineata proteasome subunit beta 5 gene that triggers the RNA-interference pathway and is designed to have limited non-target effects. To test this hypothesis, we...
Earlier fall precipitation increases the competitive advantage of non-native plant communities in a desert ecosystemNARA Subscribed
Climate change is likely to influence competitive interactions between native and non-native plant species by altering soil resource availability. The objective of this study was to characterize how shifts in fall precipitation timing due to climate change affect plant community assembly of native and non-native plant communities. We selected common non-native annuals and native perennial species from the Great Basin Desert in...
Prolonging survival in good health is a fundamental societal goal. However, the leading determinants of disability-free survival in healthy older people have not been well established. Data from ASPREE, a bi-national placebo-controlled trial of aspirin with 4.7 years median follow-up, was analysed. At enrolment, participants were healthy and without prior cardiovascular events, dementia or persistent physical disability. Disab...
Aim To determine the taxonomic identity of zooarchaeological gadfly petrel ( Pterodroma ) specimens from northern Europe, in order to investigate whether an unknown, now‐extinct Pterodroma species formerly occurred in this region, or whether extant north‐east Atlantic gadfly petrel populations now restricted to the Macaronesian Islands formerly had a much wider Holocene distribution. Location Zooarchaeological Pterodroma mater...
Hispaniola is a geotectonically complex island consisting of two palaeo‐islands that docked c. 10 Ma, with a further geological boundary subdividing the southern palaeo‐island into eastern and western regions. All three regions have been isolated by marine barriers during the late Cenozoic and possess biogeographically distinct terrestrial biotas. However, there is currently little evidence to indicate whether Hispaniolan mamm...
