XbaI polymorphism in the APOB gene and its association with increased cholesterol in children and adolescents: Ouro Preto study.

Atherosclerotic vascular changes can begin during childhood, providing risk for cardiovascular disease (CVD) in adulthood. Identifiable risk factors such as dyslipidemia accelerate this process for some children. The apolipoprotein B (APOB) gene could help explain the inter-individual variability in lipid levels among young individuals and identify groups that require greater attention to prevent CVD.

Immunization and challenge trials in a murine model using different inactivated recombinant vaccines against H1N1 swine influenza virus circulating in Brazil.

In Brazil, at least four lineages of influenza A virus circulate pig population: 2009 H1N1 flu pandemic (pH1N1), human-seasonal origin H3N2, H1N1 and H1N2 (huH1 lineages) viruses. Studies related to the occurrence of swine influenza A virus (SIAV) in Brazilian herds have been detecting an increase of occurrence of huH1 lineages. This study aimed to construct recombinant vaccines against the huH1N1 virus and test the immunogens in a murine model.

Hidden target, hidden effects: chlorantraniliprole on the coffee leaf miner (Leucoptera coffeella).

Agricultural insecticide usage presents a complex challenge, particularly when addressing hidden targets such as concealed pest species. Typically, insecticide spraying targets either the host plant or the soil substrate, reaching the target when the pests move or feed, yet their vulnerability when concealed remains low. This study delves into the often-obscure effects of insecticides on hidden herbivore species, focusing specifically on the diamide insecticide chlorantraniliprole and its impact on the concealed insect herbivore, the coffee leaf miner Leucoptera coffeella (Guérin-Mèneville & Perrottet) (Lepidoptera: Lyonetidae).

Diversity and role of volatile terpene and terpenoid pheromones in insects.

Insect pheromones are critical chemical signals that regulate intraspecific behavior and play a key role in the dynamic monitoring and control of pest populations. Historically, research on insect pheromones has primarily focused on lipid-based compounds. However, terpenes and terpenoids, which are widely occurring classes of bioactive compounds, also play significant roles in insect pheromone blends.

Resistance monitoring of diamide insecticides and characterization of field-evolved chlorantraniliprole resistance among Chinese populations of the tomato pinworm Phthorimaea (=Tuta) absoluta (Lepidoptera: Gelechiidae).

The tomato pinworm, Phthorimaea (=Tuta) absoluta, is considered one of the most destructive and invasive insect pests worldwide, having developed significant resistance to many popular insecticides. In this study, we monitored the field resistance of P. absoluta populations from China to three diamide insecticides: flubendiamide, chlorantraniliprole, and cyantraniliprole.
