the severe epidemics of fusarium head blight (fhb) as a devastating disease of cereal crops has occurred on wheat in north and northwest iran in recent years. the in vitro production of deoxynivalenol (don) was qualitatively evaluated in 41 fusarium isolates collected from wheat heads associated with the scab disease, in moghan area/northwest iran. infected wheat heads were collected during 200...

From a notice in the British and Foreign Medico-Clururgical Review, we learn that Don R. H. Poggio has lately published, at Madrid, a work on " Red Fever" or dengue. The book is "regarded as a valuable addition t) the history of this strange exotic. It-contains ample references, and the tone is thoughtful and philosophical throughout." Don Poggio informs us that dengue broke out as an epidemic ...

Immunoaffinity columns (IACs) are a well-established tool in the determination of regulated mycotoxins in food and feed commodities. However, they also have the potential to become attractive pre-concentration and clean-up materials for the determination of masked (also called modified) mycotoxins, which have been recognised as important contributors to the toxicological hazard deriving from fun...

leprosy is an ancient disease, known from south asia since at least 2000 bce. while there is no physical evidence of this disease in the region before about 50 ce, five different words are translated as “leprosy” in mesopotamian texts and some of them occur frequently. based on the texts, one word (garāṣu) is rarely used and there is evidence that the other four words relate to diseases that we...

Numerous reports indicate that learning and memory of conditioned responses are accompanied by genesis of dendritic spines in the hippocampus, although there is a conspicuous lack of information regarding spine modifications after behavioral extinction. There is ample evidence that treatments that typically produce amnesia become innocuous when animals are submitted to a procedure of enhanced t...

Research on animal metacognition has typically used choice discriminations whose difficulty can be varied. Animals are given some opportunity to escape the discrimination task by emitting a so-called uncertain response. The usual claim is that an animal possesses metacognition if (a) the probability of picking the uncertain response increases with task difficulty, and (b) animals are more accur...

Since deoxynivalenol (DON), the main representative of Fusarium toxic secondary metabolites, is a relatively common natural contaminant in barley, its traces can be detected in many commercial beers. Our previous study reporting for the first time the occurrence of relatively high levels of DON-3-glucoside (DON-3-Glc) in malt and beer prepared from relatively "clean" barley (semiscale experimen...
