Canonical Wnt/β-catenin signaling has been suggested to promote self-renewal of pluripotent mouse and human embryonic stem cells. Here, we show that SB-216763, a glycogen synthase kinase-3 (GSK3) inhibitor, can maintain mouse embryonic stem cells (mESCs) in a pluripotent state in the absence of exogenous leukemia inhibitory factor (LIF) when cultured on(More)
Chemical trail marking and following by gregarious caterpillars,Malacosoma neustria L. (Lepidoptera: Lasiocampidae), was studied in the laboratory. As in other species ofMalacosoma, larvae deposit a trail pheromone from a sternal secretory site when searching the host for food. Larvae in the vanguard of foraging columns establish chemical trails as they(More)
A patient admitted to this hospital with Parathion poisoning had a marked reduction in serum cholinesterase activity and concentration of low density lipoprotein. The enzyme and the lipoprotein levels returned to normal with clinical recovery. Guinea pigs treated with phospholine iodide showed depressed levels of serum cholinesterase and beta-lipoprotein.(More)
