By sampling a known source of wastewater, such as a sewage influent to a wastewater treatment plant, scientists can estimate the quantity of drugs used in a community from the measured levels of illicit drugs and their metabolites excreted in urine.</p> Wed, 23 Oct 2019 13:36:20 +0000 webfull 154683 at /channels /channels/news/canadian-doctor-averted-disaster-keeping-thalidomide-out-us-240385 <p> Tue, 25 Nov 2014 16:18:04 +0000 webfull 106739 at /channels /channels/news/5m-malaria-tuberculosis-drug-discovery-research-257396 <p>University of Toronto and 苹果淫院 scientists are leading an international partnership to discover new and improved drug treatments for tuberculosis, malaria and neglected tropical diseases聽 -- thanks to a contribution from Merck Canada Inc., as well as an additional $5 million supplement to a grant from the Bill & Melinda Gates Foundation.

Unwanted symptoms are often the result of medicine going where it鈥檚 not needed and harming healthy cells. To minimize this risk, researchers in Quebec have developed nanoparticles that only release a drug when exposed to near-infrared light, which doctors could beam onto a specific site. Their report appears in the <em>Journal of the American Chemical Society</em>.</p> Wed, 20 Jan 2016 15:35:58 +0000 webfull 115366 at /channels /channels/news/palldiumii-dithiocarbamates-anticancer-metallodrugs-future-264335 <p>Most chemistry students are well aware of the anticancer properties of cisplatin, cis-Pt(NH<sub>3</sub>)<sub>2</sub>Cl<sub>2</sub>,聽 as a result of the pioneering work of Professor Barnett Rosenberg and his colleagues at the Michigan State University in the late 1960s. Over the years, this simple Pt(II) coordination complex and some structurally closely related ones have become the FDA-approved drugs of choice for cancer treatment, especially ovarian and testicular cancers.</p> Wed, 23 Nov 2016 21:04:14 +0000 webfull 123218 at /channels /channels/news/why-bar-needs-be-raised-human-clinical-trials-265437 <p>Standards for authorizing first-time trials of drugs in humans are lax, and should be strengthened in several ways, 苹果淫院 researchers argue in a paper published today in <em>Nature</em>.</p> Mon, 30 Jan 2017 15:02:51 +0000 webfull 124501 at /channels
