Nutritional Value of the Larvae of the Black Soldier Fly () and the House Fly () as a Food Alternative for Farm Animals-A Systematic Review.

Dietary alternatives using insect-based products as an alternative for farm animal nutrition have been the object of study due to the high nutritional value of these feeds and the costs related to both their production and consequently their commercialization. Thus, the use of flies, especially larvae, has a high content of proteins and lipids (fat), as well as minerals and essential nutrients for development and growth, directly impacting the production of these animals, whether meat or milk. Therefore, the objective of this study was to compile data from the literature on the nutritional value of adults and larvae of Black soldier () and housefly () as a dietary alternative for animal feed.

Neurocognitive Adverse Events Related to Lorlatinib in Non-Small Cell Lung Cancer: A Systematic Review and Meta-Analysis.

Lorlatinib has been FDA-approved as a systemic therapy for ALK/ROS1-positive non-small cell lung cancer (NSCLC) patients. However, it has been associated with an increased frequency of neurocognitive adverse events (NAEs). Therefore, we conducted a systematic review and meta-analysis to assess the NAEs related to lorlatinib therapy in NSCLC patients.

Nutritional composition, phenolic compounds and biological activities of selected unconventional food plants.

This review highlights the nutritional content, phytochemical compounds, and biological properties of three unconventional food plants consumed in the Amazon: ora-pro-nóbis (Pereskia aculeata Mill.), taioba (Xanthosoma sagittifolium), and vitória-régia (Victoria amazonica). These plants show significant nutritional, functional, and economic potential, which can enhance the intake of daily nutrients, energy, and bioactive compounds.

Genomic evidence reveals three W-autosome fusions in Heliconius butterflies.

Sex chromosomes are evolutionarily labile in many animals and sometimes fuse with autosomes, creating so-called neo-sex chromosomes. Fusions between sex chromosomes and autosomes have been proposed to reduce sexual conflict and to promote adaptation and reproductive isolation among species. Recently, advances in genomics have fuelled the discovery of such fusions across the tree of life.

Effect of Glycerol and Sisal Nanofiber Content on the Tensile Properties of Corn Starch/Sisal Nanofiber Films.

Currently, petroleum-derived plastics are widely used despite the disadvantage of their long degradation time. Natural polymers, however, can be used as alternatives to overcome this obstacle, particularly cornstarch. The tensile properties of cornstarch films can be improved by adding plant-derived nanofibers.
