Experiments with the Ammonium Amalgam
Experiments with the Ammonium Amalgam. [from THE AM. JOURNAL OF SCIENCE, VOL. XL, SEPT., 1865.] EXPERIMENTS WITH THE AMMONIUM AMALGAM, BY CHARLES M. WETHERILL, Ph.D., M.D. The existence of the hypothetical radical NH 4 depends less upon the characteristics of its so-called amalgam than! upon the parallelism of its salts with those of the alkalies. If, from these analogies, we accept the metallic nature of ammonium, it will be difficult to avoid assigning a similar character to the rad- icals of all of the organic bases; and especially to those which, like the compound /ammonias, have an alkaline reaction and possess physical and chemical properties so like ammonia. If such be the inference, we must admit numerous compound metals exists only in certain of , which states of combination their elements. The assumption of the elementary nature of a metal is destroyed and the ideas of the alchemists are re- ; a may vived for if NH 4 be metal and NH 3 be not one, why not other metals, esteemed elements, be also compounds. In examining the so-called ammonium amalgam one is inter- ested at the great resemblance which it bears to the amalgams proper in its physical properties. The mercury has lost its flu- idity or mobility, and, at the same time, its relations of cohesion and adhesion are very sensibly altered. It no longer coheres powerfully; but adheres to, or Wets, platinum, iron and other metals, like the potassium or sodium amalgam. When left to C. M. Wetherill—Experiments with Ammonium Amalgam. 3 itself, the swollen mass shrinks, and gradually resolves itself into NH 3(NH 0) H and Hg, because (as it is usually explained) NH 4 has 4 a great tendency to fall apart into NH 3 and H. -

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. -

Emea Public Statement on Thiomersal in Vaccines for Human Use – Recent Evidence Supports Safety of Thiomersal-Containing Vaccines
The European Agency for the Evaluation of Medicinal Products Pre-authorisation evaluation of medicines for human use London, 24 March 2004 Doc. Ref: EMEA/CPMP/VEG/1194/04/Adopted EMEA PUBLIC STATEMENT ON THIOMERSAL IN VACCINES FOR HUMAN USE – RECENT EVIDENCE SUPPORTS SAFETY OF THIOMERSAL-CONTAINING VACCINES The EMEA issued statements on the use of thiomersal in vaccines in 1999 and 2000 (EMEA/20962/99, EMEA/CPMP/1578/00). In light of recent reassuring data on the safety of thiomersal-containing vaccines, this new statement updates previous recommendations. Thiomersal, is an antimicrobial organic mercury compound that continues to be used either in the early stages of manufacturing, or as a preservative, in some vaccines. The antimicrobial action of thiomersal relates to ethylmercury, which is released after breakdown of thiomersal into ethylmercury and thiosalicylate. The Committee for Proprietary Medicinal Products (CPMP) previously advised that although there was no evidence of harm from thiomersal in vaccines other than hypersensitivity (allergic) reactions, it would be prudent to promote the general use of vaccines without thiomersal and other mercury containing preservatives, particularly for single dose vaccines. Since then, several vaccines licensed in the European Union have had thiomersal removed or levels reduced and new vaccines without thiomersal have been licensed. CPMP advice was in line with the global goal of reducing environmental exposure to mercury. The previous assessment of risks associated with ethylmercury had been based on data on methylmercury, as the toxicity profile of the two compounds was assumed to be similar. In March 2004, the CPMP reviewed the latest evidence relating to the safety of thiomersal-containing vaccines. -

Mercury in Fish – Background to the Mercury in Fish Advisory Statement
Mercury in fish – Background to the mercury in fish advisory statement (March 2004) Food regulators regularly assess the potential risks associated with the presence of contaminants in the food supply to ensure that, for all sections of the population, these risks are minimised. Food Standards Australia New Zealand (FSANZ) has recently reviewed its risk assessment for mercury in food. The results from this assessment indicate that certain groups, particularly pregnant women, women intending to become pregnant and young children (up to and including 6 years), should limit their consumption of some types of fish in order to control their exposure to mercury. The risk assessment conducted by FSANZ that was published in 2004 used the most recent data and knowledge available at the time. FSANZ intends toreview the advisory statement in the future and will take any new data and scientific evidence into consideration at that time. BENEFITS OF FISH Even though certain types of fish can accumulate higher levels of mercury than others, it is widely recognised that there are considerable nutritional benefits to be derived from the regular consumption of fish. Fish is an excellent source of high biological value protein, is low in saturated fat and contains polyunsaturated fatty acids such as essential omega-3 polyunsaturates. It is also a good source of some vitamins, particularly vitamin D where a 150 g serve of fish will supply around 3 micrograms of vitamin D – about three times the amount of vitamin D in a 10 g serve of margarine. Fish forms a significant component of the Australian diet with approximately 25% of the population consuming fish at least once a week (1995 Australian National Nutrition Survey; McLennan & Podger 1999). -

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. -
1 Submission from the EU on Mercury-Added Products And
Submission from the EU on mercury-added products and manufacturing processes using mercury or mercury compounds In accordance with Decision MC-3/16: Review of Annexes A and B, the Secretariat called in a letter dated 13 December (MC/COP3/2019/15) for submissions from Parties by 31 March 2020, including: a) Information on mercury-added products and on the availability, technical and economic feasibility, and environmental and health risks and benefits of non-mercury alternatives to mercury-added products, pursuant to paragraph 4 of article 4 of the Convention b) Information on processes that use mercury or mercury compounds and on the availability, technical and economic feasibility and environmental and health risks and benefits of mercury-free alternatives to manufacturing processes in which mercury or mercury compounds are used, pursuant to paragraph 4 of article 5 of the Convention The EU would like to share the information on a number of products and processes listed in table 1 below, where EU law is stricter than the provisions of the Convention. Each product/process is covered in an individual fiche, including data sources and references. The submission also includes a fiche on re-emerging use of mercury used as propellant in ion engines. New information has surfaced regarding this specific use which is likely to cause a significant dispersion of mercury to the environment. Note that the EU submission is based on the European Commission study on the "Collection of information on mercury-added products and their alternatives". The final report has a wider scope than the EU submission as it also covers a number of other existing or emerging uses and has been published and made available on CIRCABC. -
