Rapidly progressive femoral head necrosis due to post-traumatic hip infection: a case report.

Brucellosis is a common zoonotic infectious disease worldwide that can affect almost all organs in the human body. Osteonecrosis of the femoral head has numerous possible causes. Patients usually experience movement disorders, severe pain, and an extremely high disability rate.

[Meta-analysis of clinical effects between non-metallic materials and metallic materials by internal fixation for patellar fracture].

Objective: To systematically evaluate clinical effects of metal and non-metallic materials in internal fixation for patellar fracture.

Methods: The reports concerning about controlled trial of metallic and non-metallic materials for patellar fracture from create database to June 2018 were searched from PubMed, EMBASE, Web of science, CNKI and Wanfang data. Information was screened and taken out according to inclusion and exclusion criteria by 2 researchers, and risk of bias in non-andomised studies of interventions (ROBINS-I) was used to evaluate literature quality.

A novel colorimetric and fluorescent iminocoumarin-based chemosensor for acetate ion and its application to living cell imaging.

A novel colorimetric and fluorescent iminocoumarin-based turn-off chemosensor for acetate ion was designed and synthesized. The chemosensor could fast detect acetate ion in a 1:1 ratio within 150 ms, which could not be affected by various coexisting anions, even F(-). Futher studies showed that the detect limit was as low as 2.

A New Fluorescence Turn-On Probe for Aluminum(III) with High Selectivity and Sensitivity, and its Application to Bioimaging.

The development of novel selective probes with high sensitivity for the detection of Al(3+) is widely considered an important research goal due to the importance of such probes in medicine, living systems and the environment. Here, we describe a new fluorescent probe, N'-(4-diethylamino-2-hydroxybenzylidene)-2-hydroxybenzohydrazide (1), for Al(3+). Probe 1 was evaluated in a solution of acetonitrile/water (1:1 v/v).
