The effects in the chicken embryo assay of four Alternaria metabolites (alternariol [AOH], alternariol methyl ether [AME], altenuene [ALT], and tenuazonic acid [TA]) were investigated. Administered to 7-day-old chicken embryos by yolk sac injection, AOH, AME, and ALT caused no mortality or teratogenic effect at doses up to 1,000, 500, and 1,000 micrograms per egg, respectively. TA exhibited a c...

Objective(s): In the present study, we investigated the effect of ischemic preconditioning (IPC) on c-myb immunoreactivity as well as neuronal damage/death after a subsequent lethal transient ischemia in gerbils. Materials and Methods: IPC was subjected to a 2 min sublethal ischemia and a lethal transient ischemia was given 5 min transient ischemia. The animals in all of the groups were given ...

BACKGROUND Asian citrus psyllid (ACP), Diaphorina citri Kuwayama, transmits the causal bacteria of the devastating citrus disease huanglongbing (HLB). Because of the variation in spatial and temporal uptake and systemic distribution of imidacloprid applied to citrus trees and its degradation over time in citrus trees, ACP adults and nymphs are exposed to concentrations that may not cause immedi...

Mice inoculated either subcutaneously (s.c.) or intradermally (i.d.) with a sublethal dose of Francisella tularensis LVS are immune to a lethal intraperitoneal (i.p.) or intravenous (i.v.) challenge of LVS. Here, we show that this immunity developed quite rapidly: mice given a sublethal dose of live LVS s.c. or i.d. (but not i.v.) withstood lethal i.p., i.v., or i.d. challenge as early as 2 day...

The flounder, Platichthys flesus, is the most abundant flatfish species in the northern Baltic Sea. Juvenile P. flesus are important epibenthic predators on shallow sandy bottoms in this area, and play an important role in structuring benthic infaunal communities by both lethal and sublethal predation. These areas are affected by periodic oxygen deficiency during summer and autumn when drifting...
