Upstream Rheotaxis of Catalytic Janus Spheres.
Sharan P, Xiao Z, Mancuso V, Uspal WE, Simmchen J. Sharan P, et al. ACS Nano. 2022 Mar 22;16(3):4599-4608. doi: 10.1021/acsnano.1c11204. Epub 2022 Mar 1. ACS Nano. 2022. PMID: 35230094 Free article.
Early theoretical studies predicted a positive rheotactic response for puller-type spherical Janus micromotors. However, recent experimental studies have focused on pusher-type Janus particles, finding that they exhibit cross-stream migration in externally applied flows. . …

A Pusher and a Clip Applied to Hind Paws Under Isoflurane Sedation to Evaluate Neuropathic Pain in a CCI Model.
Nobuhara R, Ito A, Nakagawa M, Ikemoto T, Narita K, Nishihara M, Kinoshita Y, Arai YC. Nobuhara R, et al. Anesth Pain Med. 2021 Dec 21;11(6):e118299. doi: 10.5812/aapm.118299. eCollection 2021 Dec. Anesth Pain Med. 2021. PMID: 35291401 Free PMC article.
Each animal was assessed for nociceptive behavior. Pressure and mechanical threshold tests were conducted by the application of three different pushers to the center of hind paws and arterial clips to the toes while sedated with isoflurane. ...The pressure and me …

Death by heroin intoxication in a body pusher with an innovative packaging technique: case report and review of the literature.
Visentin S, Bevilacqua G, Giraudo C, Dengo C, Nalesso A, Montisci M. Visentin S, et al. Forensic Sci Int. 2017 Nov;280:8-14. doi: 10.1016/j.forsciint.2017.08.030. Epub 2017 Sep 8. Forensic Sci Int. 2017. PMID: 28942079 Review.
Death due to mechanical or chemical intoxication of heroin body packers, thanks to the continuous improvement in packaging techniques, are increasingly rare, and almost all the cases reported in the literature refer to drug swallowers. A case of fatal acute heroin intoxica …
