Cephalosporins are one of the most commonly prescribed classes of antibiotics. Immediate IgE-mediated hypersensitivity reactions have been reported with use of a specific cephalosporin, as a cross-reaction between different cephalosporins or as a cross-reaction to other β-lactam antibiotics, namely, penicillin. Historically, frequent reports of anaphylaxis following administration of first- and ...

Virus-induced gene silencing is based on the sequence-specific degradation of RNA. Here, a gene silencing vector derived from EuMV-YP, named pEuMV-YP:ΔAV1, was used to silence ChlI and NPR1 genes in Nicotiana benthamiana. The silencing of the ChlI transcripts was efficient in the stems, petioles and leaves as reflected in tissue ...

Interactions between individuals of different cetacean species are often observed in the wild. Killer whales (Orcinus orca) can be potential predators of many other cetaceans, and the interception of their vocalizations by unintended cetacean receivers may trigger anti-predator behavior that could mediate predator-prey interactions. We explored the anti-predator behaviour of ...

Background: Current tissue-engineered cartilage constructs contain insufficient amounts of collagen, whose function is to resist tension. We postulate that dynamic tension is necessary to stimulate collagen formation. Another shortcoming is that TE cartilage does not possess native zonal variations. We hypothesize that applying depth-varying mechanical cues would stimulate ECM synthesis ...
