Integrated one‐pot CRISPR‐Cas detection: Addressing strategies and future prospects

Interdisciplinary Medicine, EarlyView.
Integrated one‐pot CRISPR‐Cas detection significantly simplifies workflows, reduces cross‐contamination risks, and shortens turnaround times, making it highly suitable for point‐of‐care testing (POCT) and resource‐limited settings. Key challenges include system compatibility issues between Cas proteins and isothermal amplification, limited multiplexing

Aflatoxin-Guanine DNA Adducts and Oxidatively Induced DNA Damage in Aflatoxin-Treated Mice in Vivo as Measured by Liquid Chromatography-Tandem Mass Spectrometry with Isotope Dilution [PDF]

, 2018
Dietary exposure to aflatoxin B1 (AFB1) is a significant contributor to the incidence of hepatocellular carcinomas globally. AFB1 exposure leads to the formation of AFB1-N7-guanine (AFB1-N7-Gua) and two diastereomers of the imidazole ring-opened 8,9 ...

Intraspecific aflatoxin inhibition in Aspergillus flavus is thigmoregulated, independent of vegetative compatibility group and is strain dependent. [PDF]

PLoS ONE, 2011
Biological control of preharvest aflatoxin contamination by atoxigenic stains of Aspergillus flavus has been demonstrated in several crops. The assumption is that some form of competition suppresses the fungus's ability to infect or produce aflatoxin ...

Immunomodulatory and Cytotoxic Properties of Enniatin B1 in Porcine Alveolar Macrophages

Journal of Applied Toxicology, EarlyView.
ABSTRACT This study investigates the immunomodulatory effects of Enniatin B1 (ENNB1), an emerging mycotoxin, on porcine alveolar macrophages (PAMs), a species‐specific model relevant to human innate immunity. PAMs were exposed to increasing ENNB1 concentrations (0.5–6 μM) over 6, 24, and 48 h.

Case–Control Study of an Acute Aflatoxicosis Outbreak, Kenya, 2004 [PDF]

, 2005
OBJECTIVES: During January-June 2004, an aflatoxicosis outbreak in eastern Kenya resulted in 317 cases and 125 deaths. We conducted a case-control study to identify risk factors for contamination of implicated maize and, for the first time, quantitated ...

Evaluation of Maize Germplasm for Resistance to Aflatoxin Accumulation

Agronomy, 2012
Aflatoxin contamination of maize grain threatens human food and animal feed safety. Breeding for reduced grain aflatoxin accumulation is one of the best strategies presently available to lower grain aflatoxin accumulation.
