Bilateral injection of naloxone (3.0-30.0 nmol) into the substantia nigra of morphine-dependent rats produced a withdrawal syndrome consisting of wet-dog shakes, teeth chattering, irritability to touch, diarrhea and hypothermia. Intense wet-dog shakes and grooming were observed after intranigral injection of the mu selective antagonist(More)
Invasive infection often begins with asymptomatic colonization of mucosal surfaces. A murine model of bacterial colonization with Streptococcus pneumoniae was used to study the mechanism for mucosal protection by immunoglobulin. In previously colonized immune mice, bacteria were rapidly sequestered within large aggregates in the nasal lumen. To further(More)
Tb 3+ -Yb 3+ co-doped SiNx down-conversion layers compatible with silicon Photovoltaic Technology were prepared by reactive magnetron co-sputtering. Efficient sensitization of Tb 3+ ions through a SiNx host matrix and cooperative energy transfer between Tb 3+ and Yb 3+ ions were evidenced as driving mechanisms of the down-conversion process.
