Photoluminescence imaging of single photon emitters within nanoscale strain profiles in monolayer WSe.

Local deformation of atomically thin van der Waals materials provides a powerful approach to create site-controlled chip-compatible single-photon emitters (SPEs). However, the microscopic mechanisms underlying the formation of such strain-induced SPEs are still not fully clear, which hinders further efforts in their deterministic integration with nanophotonic structures for developing practical on-chip sources of quantum light. Here we investigate SPEs with single-photon purity up to 98% created in monolayer WSe via nanoindentation.

[New possibilities in antibacterial treatment of intra-abdominal infections caused by multiresistant microflora].

Aim: To determine the place of new drugs with activity against multidrug resistant strains of microorganisms in the treatment of complicated intraabdominal infections.

Material And Methods: The incidence and distribution of pathogens isolated from intra-abdominal specimens in patients with intra-abdominal infections are analyzed.

Results: The current situation on the growth of resistant strains among pathogens causing intra-abdominal infections is rewied.

Partial clinical response to anakinra in severe palmoplantar pustular psoriasis.

Background: Palmoplantar pustular psoriasis is a clinical psoriasis variant characterised by a high impact on quality of life and poor response to biologics approved for plaque type psoriasis.The recombinant interleukin-1 (IL-1) receptor antagonist anakinra has been recently used for the treatment of isolated refractory cases of generalised pustular psoriasis with contrasted results.

Objectives: To report the clinical response in two patients treated with anakinra as salvage therapy in two patients with severe palmoplantar pustular psoriasis refractory to currently available antipsoriatic systemic therapies.
