fruits (, , and ) were used as food and medicine by Chilean indigenous people. This study aimed to evaluate the bioactive properties of these berry-type fruits. The antioxidant capacity determined by the FRAP assay varied between 10.4 and 646.9 mmol Fe/g, while the antibacterial activity against and was 0 - 33 mm and 0 - 7.33 mm, respectively. All the extracts were rich in polyphenols and showed low cytotoxicity. Overall, presented dissimilar results compared to those of and , encouraging the use of these native fruits as food, nutraceutical, or pharmacological ingredients.

Enhancing crops productivity to ensure food security is one of the major challenges encountering agriculture today. A promising solution is the use of biostimulants, which encompass molecules that enhance plant fitness, growth, and productivity. The regulatory metabolite zaxinone and its mimics (MiZax3 and MiZax5) showed promising results in improving the growth and yield of several crops.

Stingless bees (tribe Meliponini), comprising over 600 known species within the largest group of eusocial bees, play a critical role in ecosystem functioning through their pollination services. They contribute to the reproduction of numerous plant species, including many economically important crops such as cacao, coffee, and various fruits. Beyond their ecological significance, stingless bees hold cultural and economic importance for many native and rural communities, where they are managed for their honey, pollen, and propolis for nutritional and health purposes.

This study presents a feasible, one-pot synthesis approach for the preparation of a composite biopolymer material derived from tamarind seed xyloglucan (XG) by utilizing isocyanate chemistry. Through a facile reaction process, urethane bonds are formed in XG, resulting in the formation of a crosslinked network. FTIR spectra confirm the successful urethane link formation in XG via the OH-NCO reaction, and CHN analysis provides insights into the elemental composition.

The black puçá (Mouriri pusa) is an unconventional fruit from the Cerrado region of Brazil, commonly known as the jabuticaba of the forest. However, data on its nutritional and phytochemical composition are limited. This study investigated the nutritional composition, physicochemical characteristics, profile of carbohydrates and organic acids, phenolics and flavonoids individual, amino acids composition, bioactive substances, and antioxidant potential in the pulp, peel, and seed fractions of puçá-preto.

Uncouplers of mitochondrial electron transport chain, such as 2,4-dinitrophehol (DNP), can mimic calorie restriction by decreasing efficiency of adenosine triphosphate (ATP) synthesis. However, DNP is also a toxic substance, whose overdosage can be lethal. In the fruit fly, Drosophila melanogaster model, we have found that DNP in concentrations of 0.
