The carboxylation of sp 3 -hybridized C–H bonds with CO 2 is a challenging transformation.
Herein, we report a visible-light-mediated carboxylation of benzylic C–H bonds with CO 2 …

Autophagy has been recently demonstrated to control cell and tissue homeostasis, including
the functions of various metabolic tissues. However, it remains unclear whether autophagy …

Despite the great potential of radical chemistry in organic synthesis, N‐heterocyclic carbene
(NHC)‐catalyzed reactions involving radical intermediates are not well explored. This …

An external oxidant-free oxidative coupling for aromatic C–H thiolation by visible-light
photoredox cobalt-catalysis has been developed. Various substrates could afford benzothiazoles …

Cross-dehydrogenative-coupling reaction has long been recognized as a powerful tool to
form a C–C bond directly from two different C–H bonds. Most current processes are performed …

The authors examined the hypothesis that perinatal factors influence the onset of puberty.
Children born as singletons in Uppsala, Sweden, in 1973–1977 were followed for height …

Hypothalamic neuropeptides play essential roles in regulating energy and body weight
balance. Energy imbalance and obesity have been linked to hypothalamic signaling defects in …

Three-dimensional (3D) bioprinting combines biomaterials, cells and functional components
into complex living tissues. Herein, we assembled function-control modules into cell-laden …

An alkyne−azide addition, ie, click, reaction in conjunction with an electrostatic self-assembly
and covalent fixation (ESA-CF) process has been demonstrated to effectively construct a …

Three-dimensional (3D) bioprinting technology offers the possibility to deliver, in a defined
and organized manner, scaffolding materials and living cells, and therefore holds much …
