Interference of griseofulvin with the segregation of chromosomes at mitosis in diploid Aspergillus nidulans

Low concentrations of the antibioticgriseofulvin were found to cause increased frequencies of somatic segregation due to chromosome nondisjunction in a diploid strain ofAspergillus nidulans.

Meca Aflatoxins (AFs) are produced mainly by the molds Aspergillus flavus and Aspergillus parasiticus. Aflatoxin B1 (AFB1) is classified as carcinogenic to humans. The aim of this study was to evaluate the capacity of different strains of Lactobacilli (Lb.) and Bifidobacteria (Bf.) to reduce the bioaccessibility of AFB1 and aflatoxin B2 (AFB2), spiked in loaf bread, using a dynamic in vitro simulated gastrointestinal digestion system. ...

Infection of the skin by Aspergillus speciesmost commonly occurs through direct innoculation of damaged skin, in which case it is called primary cutaneous aspergillosis (PCA). PCA is often a devastating and life-threatening infection that has been described in all age groups. Premature neonates are at particular risk due to a smaller pool of monocytes and neutrophils, impaired T-cell activation and an immature skin barrier as well as considerably decreased cord blood TNF- α and IL-6. Skin maceration, moisture buildup and disruption of barrier integrity are believed to contribute to the pathophysiology of PCA, and occ...

AbstractChronic suppurative otitis media (CSOM) has a substantial worldwide prevalence and is a major cause of hearing impairment. In cases of CSOM unresponsive to local antibiotics, superimposed fungal infection should be suspected. The aim of the present study was to study the spectrum of cases with fungal otitis media. The study was conducted over a period of 12  years (2006–2017). Fifteen cases of CSOM clinically not suspected to be of fungal etiology that underwent surgery with identification of fungal organisms on histopathology were included in the study. Age of the patients ranged from 12 to 75 year...

Abstract The essential oil obtained from Wedelia urticifolia growing in Hunan Province, China, was analyzed for the first time by capillary GC and GC-MS. A total of 67 constituents, representing 98.68% in essential oil were identified. The major constituents of the oil were: α-pinene (8.85%), limonene (6.38%), carvacrol (6.15%), caryophyllene (6.08%), spathulenol (5.49%), sabinene (5.36%), camphor (4.34%). Antimicrobial potential of oil against bacterial strains (Pseudomonas aeruginosa, Escherichia coli and Bacillus subtilis, and Staphylococcus aureus), yeast strains (Hansenula anomala and Saccharomy cescere...

Two new isocoumarins, (3R)-methyl-8-hydroxy-6-(hydroxymethyl)-7-methoxydihydroisocoumarin (1) and (3R)-methyl-7,8-dimethoxy-6-(hydroxymethyl)dihydroisocoumarin (2), together with three known isocoumarins (3–5), were isolated from the fermentation products of an endophytic fungus Aspergillus versicolor. Their structures were elucidated by spectroscopic methods, including extensive 1D and 2D NMR techniques. The anti-tobacco mosaic virus (anti-TMV) activities of compounds1 and2 were evaluated. Compounds1 and2 showed anti-TMV activities with inhibition rates of 21.8 and 18.6% at the concentration of 20 μM, respectively.
