Characteristics of H7N9 avian influenza pneumonia: a retrospective analysis of 17 cases.

Background: H7N9 avian influenza is an infection of public health concern, in part because of its high mortality rate and pandemic potential.

Aims: To describe the clinical features of H7N9 avian influenza and the response to treatment.

Methods: Clinical, radiological and histopathological data, and treatment-related of H7N9-infected patients hospitalised during 2014-2017 were extracted and analysed.

Preparation of Stabilizer-Free Silver Nanoparticle-Coated Micropipettes as Surface-Enhanced Raman Scattering Substrate for Single Cell Detection.

In this work, we established a convenient while reproduceable method for stabilizer-free silver nanoparticle (AgNP)-coated micropipettes by the combination of magnetron sputtering and surface coupling agent. The clear surfaces of the AgNPs are beneficial for absorbing biological or functional molecules on their surfaces. By optimizing the operating parameters, such as sputtering current and sputtering time, the tip of micropipettes coated with AgNPs exhibits excellent surface-enhanced Raman scattering (SERS) performance.
