Screening the mutagenic activities of coomonly used antiparasite drugs by the Simultest, a simplified Salmonella/microsome plate incorporation assay Rastreamento de atividade mutagênica de drogas anti-parasitárias de uso comum pelo Simultest, uma versão simplificada do teste Salmonella/fração microssomal

open access: yesRevista do Instituto de Medicina Tropical de São Paulo, 1990
The mutagenic activities of 16 anti-parasite drugs were screened by the Simultest in both qualitative (spot test) and quantitative (plate incorporation) assays with a Salmonella typhimurium pool composed by the indicator strains TA97, TA 98, TA100 and ...

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry

open access: yesAdvanced Functional Materials, EarlyView.
In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...

Potential hazard of simultaneous occurrence of aflatoxin B-1 and ochratoxin A

open access: yesVeterinární Medicína, 2001
Contents of aflatoxin B1 (AFB1) and ochratoxin A (OA) in the samples of wheat and barley were detected by RIA method. Average contents of AFB1 in the samples of wheat and barley were 2.4 µg/kg and 2.2 µg/kg, respectively.

Role of Histidine‐Containing Peptoids in Accelerating the Kinetics of Calcite Growth

open access: yesAdvanced Functional Materials, EarlyView.
Amphiphilic histidine‐containing peptoids mimic carbonic anhydrase (CA) to accelerate calcite step growth. In the presence of Zn2+, they promote the deprotonation of HCO3−, the desolvation of Ca2+, and the reorganization of interfacial hydration layers, thereby reducing the activation barrier for calcite growth.

Possible Genotoxic Effects of Post-Harvest Fungicides Applied on Citrus Peels: Imazalil, Pyrimethanil, Thiabendazole and Their Mixtures

open access: yesFoods
Post-harvest fungicides are frequently used on citrus peels to reduce post-harvest fungal contamination during the storage and transport of products. Despite these positive effects, fungicides can pose health risks to consumers.

Universal Electronic‐Structure Relationship Governing Intrinsic Magnetic Properties in Permanent Magnets

open access: yesAdvanced Functional Materials, EarlyView.
Permanent magnets derive their extraordinary strength from deep, universal electronic‐structure principles that control magnetization, anisotropy, and intrinsic performance. This work uncovers those governing rules, examines modern modeling and AI‐driven discovery methods, identifies critical bottlenecks, and reveals electronic fingerprints shared ...
