Background: The low glyphosate uptake capacity, possibly due to the lipophilic character of epicuticular wax on leaves, may contribute to the natural tolerance of some weed species. The use of pre-emergence herbicides like S-metolachlor, which inhibits very-long-chain fatty acid synthesis, might enhance glyphosate's post-emergent efficacy against hard-to-control weeds, such as Euphorbia heterophylla L. (milkweed) and Ipomoea triloba L.

The application of exogenous RNA for gene-silencing strategies has gained significant traction in agriculture, offering a highly efficient and eco-friendly alternative to conventional plant protection methods. This success has been driven by advances in biotechnology, from the design of long double-stranded RNA (dsRNA) and small interfering RNA (siRNA) molecules to the development of nanocarrier systems that address the challenge of RNA delivery into plant cells. In particular, polymer-based nanocarriers have emerged as a promising solution for enhancing the stability and delivery efficiency of RNA molecules.

The South American fruit fly (Wiedmann) has a vast range extending from northern Mexico, through Central America, to South America where it is an extremely polyphagous pest of wild and cultivated fruits. It is a complex of cryptic species currently composed of eight recognised morphotypes: "Mexican", "Venezuelan", "Andean", "Peruvian", "Ecuadorian", and the three Brazilian morphotypes "Brazilian-1", "Brazilian-2", and "Brazilian-3". Molecular markers that can identify the member species of the complex are crucial for the implementation of effective pest control measures, such as the sterile insect technique.

Background: Congenital heart disease (CHD) is a leading cause of childhood morbidity, with an estimated prevalence of 0.8-1%. However, advances in diagnosis and treatment now allow 90% of childhood CHD patients to survive to adulthood, leading to increased interest in their quality of life (QoL).

Article Synopsis
  • Chikungunya virus (CHIKV) can lead to severe diseases, including chronic arthritis and, in rare cases, neurological issues and death, primarily transmitted by mosquitoes.
  • A comprehensive study revealed that deaths from CHIKV are linked to multi-organ infections, serious brain damage, and higher levels of inflammation in the body compared to survivors.
  • The research also found that CHIKV infection disrupts the blood-brain barrier, leading to increased permeability and changes in protein expression, enhancing our understanding of CHIK pathophysiology and fatal outcomes.
