Introduction: Few data on the impact of specific interventions against Emergency Rooms 'or Hospitals overcrowding are available in France.
Methods: In the present report, we retrospectively investigated the impact of the implementation of a short-stay observation unit associated with the admitter-rounder model, especially onto the other in-patient internal medicine units in a French University Hospital.
Results: During the first 100 days, 242 patients were admitted into the short-stay observation unit.

Herein, a new metal-free, molecular chlorine-free, environmentally friendly, atom-economical, short time, inexpensive and simple operation method with mild reaction conditions for chlorination of alkenes, cyclic alkenes, ,-unsaturated carbonyl compounds, heteroaromatics, and natural products was reported with up to 96% yields using trichloroisocyanuric acid (TCCA) as the electrophilic chlorine source and TBACl as the nucleophilic chlorine source. It was demonstrated with bicyclic alkene benzonorbornadiene that regioselective chlorobromination and dibromination reactions can be carried out through TCCA/TBABr redox reactions, where TCCA acts as an oxidant in the presence of TBABr. The structures of the redox products were confirmed as a result of control experiments conducted with the newly presented DBI/TBACl and DBI/TBABr halogenation pairs.

Atomically precise metal nanoclusters (NCs) and metal-organic frameworks (MOFs) possess distinct properties that can present challenges in certain applications. However, integrating these materials to create new composite functional materials has gained significant interest due to their unique characteristics through a range of applications, particularly in catalysis. Considering MOFs as hosts and NCs as guests, several synergistic effects have been observed in composites, particularly in environmental catalytic reactions.

Asymmetric cell division (ACD) allows daughter cells of a polarized mother to acquire different developmental fates. In , the Wnt/β-catenin Asymmetry (WβA) pathway regulates many embryonic and larval ACDs; here, a Wnt gradient induces an asymmetric distribution of Wnt signaling components within the dividing mother cell. One terminal nuclear effector of the WβA pathway is the transcriptional activator SYS-1/β-catenin.

RNA interference (RNAi) has rapidly matured as a novel therapeutic approach. In this field, chemical modifications have been critical to the clinical success of short interfering RNAs (siRNAs). Notwithstanding the significant advances, achieving robust durability and gene silencing in extrahepatic tissues, as well as reducing off-target effects of siRNA, are areas where chemical modifications can still improve siRNA performance.
