Physicochemical characteristics, mycoflora and aflatoxins in corn grown and stored in Northern Tamaulipas, Mexico.

In northern Tamaulipas, México, the contamination of corn by toxigenic fungi reduces grain production and quality. Corn contaminated by mycotoxins puts humans and livestock at risk. Continuous monitoring of the sanitary quality of grain at harvest and in storage will define preventive and corrective strategies for contamination by mycotoxigenic fungi.

Risk factors associated with intraventricular hemorrhage in very-low-birth-weight premature infants.

Purpose: To analyze the association between risk factors and severe intraventricular hemorrhage (grade II-IV) in PNB under 1500 g.

Methods: Multicenter, retrospective, analytical, case-control study in PNB under 34 weeks and under 1500 g admitted to the NICU.

Case: PNB with severe intraventricular hemorrhage (grade II-IV).

evaluation of the antagonistic activity of native strains of spp. against spp.

Advances in Control Strategies against . A Review.

The strategies for controlling the insect pest have been developing over the past four decades; however, the insecticide resistance and the remarkable adaptability of this insect have hindered its success. This review first analyzes the different chemical compounds currently available and the most promising options to control . Then, we analyze the metabolites obtained from plant extracts with antifeedant, repellent, insecticide, or ovicide effects that could be environmentally friendly options for developing botanical insecticides.
