Catalytic Asymmetric α-Functionalization of α-Branched Aldehydes
(MDPI, 2023-03-16)
Aldehydes constitute a main class of organic compounds widely applied in synthesis. As such, catalyst-controlled enantioselective α-functionalization of aldehydes has attracted great interest over the years. In this context, ...
Reducing Negative Aging Stereotypes via Educational Intervention in Older People: A Randomized Controlled Study
(Sage, 2022-09-13)
Anti-ageism interventions traditionally target younger individuals. We analyzed the effect of an educational intervention that combined an infusion of aging content with videos to reduce negative stereotypes toward aging ...
Organocatalytic Michael Addition of Unactivated α-Branched Nitroalkanes to Afford Optically Active Tertiary Nitrocompounds
(ACS, 2023-11-27)
The direct, asymmetric conjugate addition of unactivated α-branched nitroalkanes is developed based on the combined use of chiral amine/ureidoaminal bifunctional catalysts and a tunable acrylate template to provide tertiary ...
Development of an α’-hydroxy enone for the aminocatalytic asymmetric formal conjugate addition of aldehydes to acrylates, vinyl ketones and acrolein
(Royal Society of Chemistry, 2023-05-24)
Aminocatalytic asymmetric conjugate addition of aldehydes to Michael acceptors is a well established C–C bond forming methodology. However, various acrylic-type acceptors, including acrylic acid derivatives and acrolein, ...
Progress in (Thio)urea‐ and Squaramide‐Based Brønsted Base Catalysts with Multiple H‐Bond Donors
(Wiley, 2023-02)
Nowadays chiral (thio)urea- and squaramide-based Brønsted base catalysts are widely applied to enantioselective carbon-carbon and carbon-heteroatom bond forming reactions. In recent years, variations of these catalysts ...
Characterization of the Antitumor Potential of Extracts of Cannabis sativa Strains with High CBD Content in Human Neuroblastoma
(MDPI, 2023-02-14)
Cannabis has been used for decades as a palliative therapy in the treatment of cancer. This is because of its beneficial effects on the pain and nausea that patients can experience as a result of chemo/radiotherapy. ...
Ionic Liquid-Laden Zn-MOF-74-Based Solid-State Electrolyte for Sodium Batteries
(MDPI, 2023-12-12)
Sodium batteries are receiving increasing interest as an alternative to reduce dependence on lithium-based systems. Furthermore, the development of solid-state electrolytes will lead to higher-performing and safer devices. ...
Joint association between education and polygenic risk score for incident coronary heart disease events: a longitudinal population-based study of 26 203 men and women
(BMJ Publishing Group, 2021-01-06)
Background Genetic vulnerability to coronary heart disease (CHD) is well established, but little is known whether these effects are mediated or modified by equally well- established social determinants of CHD. We estimate ...
Joint associations of depression, genetic susceptibility and the area of residence for coronary heart disease incidence
(BMJ Publishing Group, 2021-08-18)
Background Depression is a risk factor for coronary
heart disease (CHD), but less is known whether genetic
susceptibility to CHD or regional-level
social indicators
modify this association.
Methods Risk factors of CHD ...
Physical Activity and Academic Performance: Genetic and Environmental Associations
(Lippincott, Williams & Wilkins, 2020-02)
Introduction:
Physical activity and academic performance are believed to be associated. Though both traits are partially heritable, it remains unclear
whether these traits also share a genetic and/or environmental ...
