The 1948 report of the British Medical Research Council's randomized trial of streptomycin for pulmonary tuberculosis is widely regarded as marking the beginning of the modern history of controlled clinical trials. Four years earlier, however, a methodologically sophisticated multicentre trial conducted under the aegis of the Medical Research Council was reported, which assessed the effects of ...
Subgenera and sections have traditionally been used in Penicillium classifications. In the past, this sectional classification was based on macro- and microscopic characters, and occasionally supplemented with physiological and/or extrolite data. Currently, 25 sections are accepted, largely based on phylogenetic data. Certain sections of subgenus Penicillium were never studied in detail using a...
Kinetic analyses of the mechanisms of patulin- and gossypol-induced cellular toxicity in an immortalized rat hepatocyte cell line were examined using a battery of vital fluorescence bioassays. Intracellular glutathione (GSH) content and intracellular Ca2+ ([Ca2+])i were monitored simultaneously using fluorescent probes requiring uv excitation (351-363 nm); reactive oxygen species (ROS) producti...
Penicillium expansum is among the most ubiquitous fungi disseminated worldwide, that could threaten the fruit sector by secreting patulin, a toxic secondary metabolite. Nevertheless, we lack sufficient data regarding the growth and the toxigenesis conditions of this species. This work enables a clear differentiation between the favorable conditions to the P. expansum growth and those promising ...
Patulin is a mycotoxin produced by several Penicillium, Aspergillus, and Byssachlamys species growing on food products. In this study, we investigated the effects of patulin on the thymus of growing male rats aged five to six weeks. The rats were receiving it orally at a dose of 0.1 mg kg-1 bw a day for either 60 or 90 days. At the end of the experiment, the thymus was examined for histopatholo...
Amaç: Patulin, başta Aspergillus ve Penicilium olmak üzere bazı küf mantarları tarafından üretilen bir mikotoksin olup, hayvanlarda insanlarda mikotoksikozdan sorumludur. Patulinin antitümör aktivitesi hakkında hala çok ayrıntılı veriler bulunmamakla birlikte raporlar hücresel apoptozu toksisiteyi indüklediğini göstermektedir. Bizim bu çalışmadaki amacımız patulinin insan karaciğer akciğer kans...
The presence of mycotoxins in grains is well documented. Workers in grain handling occupations are commonly exposed to grain dust aerosols. Work in our laboratory has shown that T-2 toxin is highly toxic to rat alveolar macrophages in vitro, causing loss of viability, release of radiolabeled chromium, inhibition of macromolecular synthesis, inhibition of phagocytosis, and inhibition of macropha...
Mycotoxins are toxic secondary metabolites produced under special conditions of moisture and temperature by aerobic, microscopic fungi that can colonize a variety of foods from before harvest up to consumer use. Contamination of beverages, including that of apple juice by patulin and coffee, beer and wine by ochratoxin A has gained worldwide interest in recent years with the revelation of the e...
