Selling Mercury Cosmetics and Pharmaceuticals (W-Hw4-22)
www.pca.state.mn.us Selling mercury cosmetics and pharmaceuticals Mercury-containing skin lightening creams, lotions, soaps, ointments, lozenges, pharmaceuticals and antiseptics Mercury is a toxic element that was historically used in some cosmetic, pharmaceutical, and antiseptic products due to its unique properties and is now being phased out of most uses. The offer, sale, or distribution of mercury-containing products is regulated in Minnesota by the Minnesota Pollution Control Agency (MPCA). Anyone offering a mercury-containing product for sale or donation in Minnesota is subject to these requirements, whether a private citizen, collector, non-profit organization, or business. Offers and sales through any method are regulated, whether in a store or shop, classified advertisement, flea market, or online. If a mercury-containing product is located in Minnesota, it is regulated, regardless of where a purchaser is located. Note: This fact sheet discusses the requirements and restrictions of the MPCA. Cosmetics and pharmaceuticals may also be regulated for sale whether they contain mercury or not by other state or federal agencies, including the Minnesota Board of Pharmacy and the U.S. Food & Drug Administration. See More information on page 2. What are the risks of using mercury-containing products? Use of mercury-containing products can damage the brain, kidneys, and liver. Children and pregnant women are at increased risk. For more information about the risks of mercury exposure, visit the Minnesota Department of Health. See More information on the page 2. If you believe you have been exposed to a mercury-containing product, contact your health care provider or the Minnesota Poison Control Center at 1-800-222-1222. -
A Screening-Based Approach to Circumvent Tumor Microenvironment

Shelat3, Amandeep Singh4, Nidal Boulos1, Richard T. Williams1,2*, and R. Kiplin Guy2,3 Abstract Signaling by the BCR-ABL fusion kinase drives Philadelphia chromosome–positive acute lymphoblastic leukemia (Ph+ ALL) and chronic myelogenous leukemia (CML). Despite their clinical activity in many patients with CML, the BCR-ABL kinase inhibitors (BCR-ABL-KIs) imatinib, dasatinib, and nilotinib provide only transient leukemia reduction in patients with Ph+ ALL. While host-derived growth factors in the leukemia microenvironment have been invoked to explain this drug resistance, their relative contribution remains uncertain. Using genetically defined murine Ph+ ALL cells, we identified interleukin 7 (IL-7) as the dominant host factor that attenuates response to BCR-ABL-KIs. To identify potential combination drugs that could overcome this IL-7–dependent BCR-ABL-KI–resistant phenotype, we screened a small-molecule library including Food and Drug Administration–approved drugs. Among the validated hits, the well-tolerated antimalarial drug dihydroartemisinin (DHA) displayed potent activity in vitro and modest in vivo monotherapy activity against engineered murine BCR-ABL-KI–resistant Ph+ ALL. Strikingly, cotreatment with DHA and dasatinib in vivo strongly reduced primary leukemia burden and improved long-term survival in a murine model that faithfully captures the BCR-ABL-KI–resistant phenotype of human Ph+ ALL. -
Reproducibility of Silver-Silver Halide Electrodes
U. S. DEPARTMENT OF COMMERCE NATIONAL BUREAU OF STANDARDS RESEARCH PAPER RP1183 Part of Journal of Research of the National Bureau of Standards, Volume 22, March 1939 REPRODUCIBILITY OF SILVER.SILVER HALIDE ELECTRODES 1 By John Keenan Taylor and Edgar Reynolds Smith ABSTRACT Tests of the reproducibility in potential of the electrolytic, thermal-electrolytic, and thermal types of silver-silver chloride, silver-silver bromide, and silver-silver iodide electrodes, in both acid and neutral solutions, are reported. All of these silver-silver halide electrodes show an aging effect, such that freshly prepared electrodes behave as cathodes towards electrodes previously aged in the solution. They are not affected in potential by exposure to light, but the presence of oxygen disturbs the potentials of the silver-silver chloride and silver-silver bromide elec trodes in acid solutions, and of the silver-silver iodide electrodes in both acid and neutral solutions. Except in the case of the silver-silver iodide electrodes, of which the thermal-electrolytic type seems more reliable than the electrolytic or the thermal type, the equilibrium potential is independent of the type, within about 0.02 mv.

The requirement for the prolonged treatment is thought to be due to dormant persister bacteria which are not effectively killed by the current TB drugs, except rifampin and pyrazinamide (PZA) which have higher activity against persisters. -

Risk & Policy Analysts EXECUTIVE SUMMARY Overview Mercury and its compounds are hazardous materials which may pose risks to people and to the environment. This report presents an assessment of the risks associated with the use of mercury in a range of products. The key requirements of the study were: • to identify usage of mercury in dental amalgam, batteries, measuring instruments (such as thermometers and manometers), lighting, other electrical components and other lesser uses; • to review data used to evaluate the toxicity of mercury and mercury compounds to humans and to the environment; • to derive predicted environmental concentrations (PECs) associated with use of the products under consideration and compare with those associated with other sources of mercury; and • to characterise the associated risks. -
