Palladium-Catalyzed Asymmetric Allylic Alkylation of 4-Substituted Isoxazolidin-5-ones: Straightforward Access to β2,2 -Amino Acids.
(2018-04-03)We report here an unprecedented and highly enantioselective palladium-catalyzed allylic alkylation applied to 4-substituted isoxazolidin-5-ones. Ultimately, the process provides a straightforward access to β2,2 -amino acids ... -
A pangenome graph reference of 30 chicken genomes allows genotyping of large and complex structural variants.
(2023-11-22)BACKGROUND: The red junglefowl, the wild outgroup of domestic chickens, has historically served as a reference for genomic studies of domestic chickens. These studies have provided insight into the etiology of traits of ... -
Parallel Evolution in the Integration of a Co-obligate Aphid Symbiosis
(Elsevier BV, 2020-04)Dependence on multiple nutrient- provisioning symbionts has evolved numerous times in insects. Monnin et al. provide evidence from the symbionts of aphids that these dependencies evolve in a predictable manner. The repeated ... -
Parallel independent losses of g-type lysozyme genes in hairless aquatic mammals.
(Oxford University Press, 2021-08-27)Lysozyme enzymes provide classic examples of molecular adaptation and parallel evolution, however, nearly all insights to date come from c-type lysozymes. G-type lysozymes occur in diverse vertebrates, with multiple ... -

Parasite-mediated predation determines infection in a complex predator-prey-parasite system.
(The Royal Society, 2024-04-24)The interplay of host-parasite and predator-prey interactions is critical in ecological dynamics because both predators and parasites can regulate communities. But what is the prevalence of infected prey and predators when ... -
Parental transposable element loads influence their dynamics in young Nicotiana hybrids and allotetraploids.
(Wiley on behalf of New Phytologist Trust, 2019-02)The genomic shock hypothesis suggests that allopolyploidy is associated with genome changes driven by transposable elements, as a response to imbalances between parental insertion loads. To explore this hypothesis, we ... -
Patagonian partnerships: the extinct Dusicyon avus and its interaction with prehistoric human communities.
(2024-04)The southern Mendoza province, located in the northern region of Patagonia, was inhabited by hunter-gatherer groups until historic times. Previous archaeological studies have reported canid remains among faunal assemblages, ... -
Pathfinder: A gamified measure to integrate general cognitive ability into the biological, medical, and behavioural sciences
(Springer Nature [academic journals on nature.com], 2021-10-01)Genome-wide association (GWA) studies have uncovered DNA variants associated with individual differences in general cognitive ability ( g ), but these are far from capturing heritability estimates obtained from twin studies. ... -
Patient navigation to improve breast cancer screening in Bosnian refugees and immigrants.
(Springer, 2011-10-19)Refugee women have low breast cancer screening rates. This study highlights the culturally competent implementation and reports the outcomes of a breast cancer screening patient navigation program for refuge/immigrant women ...
