Chromosomal breaks at the origin of small tandem DNA duplications

open access: yesBioEssays, Volume 45, Issue 1, January 2023., 2023
Small tandem DNA duplications form a specific mutational signature frequently found in human disease alleles and cancer genes. Here we hypothesize that these duplications mainly arise at chromosomal DNA breaks that result from two closely located single‐stranded nicks, through error‐prone repair by the non‐homologous end‐joining pathway. Abstract Small

Older patients with COVID‐19 and neuropsychiatric conditions: A study of risk factors for mortality

open access: yesBrain and Behavior, Volume 12, Issue 12, December 2022., 2022
Abstract Background Little is known about risk factors for mortality in older patients with COVID‐19 and neuropsychiatric conditions. Methods We conducted a multicentric retrospective observational study at Assistance Publique‐Hôpitaux de Paris. We selected inpatients aged 70 years or older, with COVID‐19 and preexisting neuropsychiatric comorbidities

A Transcriptome‐Wide Mendelian Randomization Study in Isolated Human Immune Cells Highlights Risk Genes Involved in Viral Infections and Potential Drug Repurposing Opportunities for Schizophrenia

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Schizophrenia is a neurodevelopmental psychiatric disorder characterized by symptoms of psychosis, thought disorder, and flattened affect. Immune mechanisms are associated with schizophrenia, though the precise nature of this relationship (causal, correlated, consequential) and the mechanisms involved are not fully understood.

Manipulation of Chemistry and Biology with Visible Light Using Tetra‐ortho‐Substituted Azobenzenes and Azonium Ions

open access: yesAngewandte Chemie, EarlyView.
Tetra‐ortho‐Azobenzenes (TOABs) in broad daylight: in recent years, TOAB photoswitches became indispensable tools for all‐visible‐light manipulation of chemistry, biology and materials. This review explores their unique photochemical properties, design and synthetic approaches, offering support in choosing a TOAB for a given application.

Copper‐Catalyzed Synthesis of C‐2 Substituted Indolin‐3‐Ones and Indolin‐3‐One [4+2] Cycloadducts Through Azide‐Tethered Iodonium Ylides

open access: yesAsian Journal of Organic Chemistry, EarlyView.
Azide‐tethered iodonium ylides under copper catalysis generate metallocarbenes that undergo intramolecular trapping by the azide moiety and generate a reactive C‐acylimine, effectively coupling two nucleophilic centers. This intermediate can be trapped by a wide range of nucleophiles or 1,3‐dienes producing complex indolin‐3‐ones and ...

Lipid metabolism in pancreatic cancer: emerging roles and potential targets

open access: yesCancer Communications, Volume 42, Issue 12, Page 1234-1256, December 2022., 2022
Abstract Pancreatic cancer is one of the most serious health issues in developed and developing countries, with a 5‐year overall survival rate currently <9%. Patients typically present with advanced disease due to vague symptoms or lack of screening for early cancer detection.

Total Synthesis of the Marine Diterpenoids Caucanolide E and F by Alkyne gem‐Hydrogenation: Rigorous Reassignment of Two Almost Indistinguishable Diastereomers

open access: yesAngewandte Chemie, EarlyView.
The application of gem‐hydrogenation, which exploits the electrophilic character of the ruthenium carbene intermediates transiently formed, to natural product total synthesis allowed the stereostructure of a pair of diastereomeric seco‐cembranoids that are almost indistinguishable by NMR to be rigorously assigned.
