We conducted a systematic review to address limited evidence suggesting that opioids may induce or aggravate obstructive sleep apnea (OSA). All clinical trials or observational studies on adults from 1946 to 2018 found through MEDLINE, EMBASE, CINAHL, PsycINFO, Cochrane Databases were eligible. We assessed the quality of the studies using published guidelines.

- - This study introduces a new method for creating molecularly imprinted polymers around gold nanorods using diazonium salt chemistry combined with the iniferter technique.
- - The approach allows for precise control over the imprinting process on a nanoscale, enhancing the effectiveness of the polymers.
- - The resulting product is water-soluble plasmonic nanosensors, which could have various applications in sensing technologies.
The water stability of iron oxide nanoparticles (NPs) is a major issue for biomedical and biological applications. This paper presents a versatile approach for preparing water-soluble iron oxide nanoparticles coated by bifunctional oligo(ethylene oxide) (OEO) chains, carrying on the one side a diazonium end group for covalent grafting at the NP surface and on the other side an iniferter group (diethyl dithiocarbamate) for initiating the growing of poly(methacrylic acid). The nanoparticles were synthesized by coprecipitation in basic media and functionalized in situ by adding the diazonium salt directly in the synthesis medium.

Methods: Forty-five patients with AMI admitted to the Coronary Care Unit, Jordan University Hospital and Queen Alia Heart Institute at King Hussein Medical Center, Amman, Jordan during the period November 1999 through to April 2000 were included in the study. Forty-five patients with non cardiac conditions were selected as a control group.
