Stereoselective vicinal C(sp³)–C bond formation via metallaphotoredox 1,2-difunctionalization of internal alkenes

Nature Communications
Achieving precise stereocontrol when forging two vicinal C(sp³)–C bonds on unsymmetrical internal alkenes remains a formidable challenge. The comparable reactivity of alkyl radicals often compromises chemo- and regioselectivity, while the concurrent ...

Assessment and Evaluation of Anatomic Variations of Retromolar Pad: A Cross Sectional Study [PDF]

Journal of Clinical and Diagnostic Research, 2016
Introduction: The retromolar pad also called piriformis papilla is a mucosal elevation located in the retromolar area covering the retromolar triangle. After molar loss, the bony alveolar process and surrounding soft periodontal tissue remodel, mainly

G-Dimension.

MATHEMATICA SCANDINAVICA, 1995
The \(G\)-dimension of complexes with finitely generated cohomology is defined. The finite \(G\)-dimension extends the corresponding notion for modules, hence extends the finite projective dimension. Among other applications, a version of the Auslander-Buchsbaum equality (for complexes with finite \(G\)-dimension) is proved.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Re-Mapping Russia from the Viewpoint of Foreign Investors - Applying a Self-Organizing Map in the Context of Russian Regions

Ekonomika, 2005
When a foreign company enters Russia, it has plenty of choices for choosing a favourable location. A country with 17 million square kilometres, 33 cities with more than 0,5 million inhabitants and 89 different administrative regions contains a wide ...

Bioinspired learning and memory in ionogels through fast response and slow relaxation dynamics of ions

Nature Communications
Mimicking biological systems’ sensing, learning, and memory capabilities in synthetic soft materials remains challenging. While significant progress has been made in sensory functions in ionogels, their learning and memory capabilities still lag behind ...

Distinct Associations of Motor Domains in Relatives of Schizophrenia Patients—Different Pathways to Motor Abnormalities in Schizophrenia?

Frontiers in Psychiatry, 2018
IntroductionAberrant motor function is an integral part of schizophrenia. In fact, abnormalities are frequently found in patients, in populations at risk, and in unaffected relatives.

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions

FEBS Letters, EarlyView.
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

Chemoselective synthesis of fluoroacetonitrile-containing terminal groups for stable non-fullerene acceptors

Nature Communications
The intrinsic instability of non-fullerene acceptors (NFAs), primarily caused by vulnerable exocyclic vinyl linkages, significantly undermines the operational lifetime of organic solar cells (OSCs).
