Related EHP Article A Method for Identifying Prevalent Chemical Combinations in the U.S. Population Dustin F. Kapraun, John F. Wambaugh, Caroline L. Ring, Rogelio Tornero-Velez, and R. Woodrow Setzer  Modern industry and manufacturing rely on a roster of more than 84,000 chemicals,1 many of which have received minimal study.2 Through programs such as ToxCast™ and Tox21, researchers are working hard to create safety profiles for as many of these compounds as possible. But while the primary paradigm in toxicology remains studying exposures to individual agents, few chemical exposures occur in isolation, and it can be difficult to predict how chemical mixtures might affect health. In a new report in Environmental Health Perspectives, researchers describe a new tool called frequent itemset mining (FIM) to identify the mixtures to which people are most commonly exposed.3 There is a “pretty big data gap” betw...

We aimed to evaluate the periodontal status in RA with and without baricitinib, a Jan...

Publication date: Available online 18 January 2020Source: Tribology InternationalAuthor(s): Xiao Kang, Alan Palazzolo, Wan ZhongAbstractAuxiliary bearings (AB) support the rotor and protect the magnetic bearing (AMB) system when the AMB is disabled due to power loss or excessive loads. The paper demonstrates that installing a damping device along with the AB can yield extended AB fatigue life, protect the AMB, and reduce vibration, contact force and AB heating. A squeeze film damper (SFD) is an energy dissipation device that has been widely used in the turbo-machinery industry, and as demonstrated in the paper can also wor...

Conclusions: Treatment of highly active RRMS with cladribine tablets was less costly and more effective than treatment with fingolimod. Hence, it is a dominant strategy in the Portuguese setting. No conclusions can be drawn from the present study regarding other treatment options, in particular natalizumab and alemtuzumab. PMID: 31951777 [PubMed - as supplied by publisher]
