A previous study had confirmed good selective features of a biofungicide based on Bacillus subtilis Ch-13 regarding green mould disease control and increase in white button mushroom (Agaricus bisporus) production. The recommended application rate the three split doses (30 + 15 ml m-2) enhanced yield by 8.41% (Trichoderma aggressivum) 53.57%. different procedure B. was then further investigated,...
Outbreaks of leaf spot disease occurred in Rehmannia glutinosa fields Henan Province, China, 2019, with the incidence ranging from 20% to 40%. R. plants diseased leaves were collected, and 25 isolates obtained. Pathogenicity tests, morphological observations, phylogenetic analyses conducted identify pathogens, biological characteristics control agents pathogens studied. Five pathogenic fungi is...
Azole resistance in human fungal pathogens has increased over the past twenty years, especially in immunocompromised patients. Similarities between medical and agricultural azoles, and extensive azole (14α-demethylase inhibitor, DMI) use in crop protection, prompted speculation that resistance in patients with aspergillosis originated in the environment. Aspergillus species, and especially Aspe...
The Leydig cells of the testis have the capacity to biosynthesize testosterone from cholesterol. Testosterone and its metabolically activated product dihydrotestosterone are critical for the development of male reproductive system and spermatogenesis. At least four steroidogenic enzymes are involved in testosterone biosynthesis: Cholesterol side chain cleavage enzyme (CYP11A1) for the conversio...
This paper presents the results from two ring-tests addressing the feasibility, robustness and reproducibility of a reproduction toxicity test with the freshwater gastropod Lymnaea stagnalis (RENILYS strain). Sixteen laboratories (from inexperienced to expert laboratories in mollusc testing) from nine countries participated in these ring-tests. Survival and reproduction were evaluated in L. sta...
BACKGROUND By disrupting the action of androgens during gestation, certain chemicals present in food, consumer products, and the environment can induce irreversible demasculinization and malformations of sex organs among male offspring. However, the consequences of simultaneous exposure to such chemicals are not well described, especially when they exert their actions by differing molecular mec...
Using a conditioned proboscis extension response (PER) assay, honeybees (Apis mellifera L.) can be trained to associate an odor stimulus with a sucrose reward. Previous studies have shown that observations of conditioned PER were of interest for assessing the behavioral effects of pesticides on the honeybee. In the present study, the effects of sublethal concentrations of nine pesticides on lea...
