The 26S proteasome operates at the executive end of the ubiquitin-proteasome pathway. Here, we present a cryo-EM single particle structure of the Saccharomyces cerevisiae 26S proteasome at a resolution of 7.4 Å or 6.7 Å (Fourier-Shell Correlation of 0.5 or 0.3, respectively).

Immune surveillance by macrophages and monocytes is important for removing foreign invaders from the body, eliminating dead or damaged cells, and tissue homeostasis. Functional plasticity of macrophages enables them to respond to different stimuli, performing a variety of immune modulatory roles. During tumor development, macrophages are among the first immune cells to migrate into the tumor. Stimuli, including molecules secreted by cancer cells, polarize macrophages into various tumor-associated macrophage subpopulations. Factors secreted by macrophages include immunosuppressive cytokines, inflammatory chemokines, and phagocytosis molecules. Shown here are multiple macrophages (white) associating with a breast cancer cell (red). At the University of New Mexico, we are using nanotechnology to deliver agents that influence immune cells to actively participate in destroying tumor cells.

Aerators should be regularly kept cleaned or replaced. The mesh in the aerator can collect lead debris, and then leach this toxic metal into the water passing through it. Aerators cap the ends of most drinking-water faucets. In some cases, they’re used to conserve water by reducing a faucet’s maximum flow rate; in others their primary function is to concentrate the flow of water so that it delivers more pressure and cleaning power. But these little metal cages also collect debris. Including lead. And unless you’re regularly cleaning out those aerators, you might be developing a toxic mini gravel field through which your drinking water must pass before reaching your glass or coffee pot. Indeed, one lead poisoning case in North Carolina involved a child (see link below): www.dcwater.com/waterquality/faqs.cfm
