MEMS is an acronym for Microelectro Mechanical Systems, it defines mechanical structures fabricated with IC processing on (most often) silicon wafers. In Europe, MEMS is labeled Microsystems and in Japan it is labeled Micromachines. The term MEMS evolved in the United States in the 1990s. Prior to that period the technology was labeled silicon micromachining . MEMS defines the technology; not s...

The directional flow of information in neurons depends on compartmentalization: dendrites receive inputs whereas axons transmit them. Axons and dendrites likewise contain structurally and functionally distinct subcompartments. Axon/dendrite compartmentalization can be attributed to neuronal polarization, but the developmental origin of subcompartments in axons and dendrites is less well underst...

Idiosyncratic hepatotoxicity has been associated with the oral tyrosine kinase inhibitor lapatinib, which is used in metastatic breast cancer therapy. Lapatinib is extensively metabolized by cytochrome P450 3A4/5 to yield an O-debenzylated metabolite, which can undergo further oxidation to a reactive quinone imine. A recent clinical study reported that concomitant use of lapatinib with dexameth...

teria are not always clear, particularly in settings where chlamydia prevalence is low—as is the case for some family planning providers. The increasing integration of STD services into family planning settings requires the development and evaluation of risk-assessment tools that are appropriate for these populations.7 When resources allocated for the prevention and control of chlamydial diseas...

The use of botanical dietary supplements has grown steadily over the last 20 years despite incomplete information regarding active constituents, mechanisms of action, efficacy, and safety. An important but underinvestigated safety concern is the potential for popular botanical dietary supplements to interfere with the absorption, transport, and/or metabolism of pharmaceutical agents. Clinical t...

The literature on labor politics explains cooperation among unions, employers and state representatives in new democracies as a function of alliances between politically infl uential unions and left governments. This article introduces an original dataset of labor agreements in new democracies (1994–2004). Using Boolean analysis, it shows that while left governments are typically associated wit...
