Climacteric and Non-Climacteric Ripening Patterns of Melons with Focus on Carbohydrate Metabolism and Osmotic Potential

This study investigated the differences between ripening patterns of two homozygous lineages of melons, yellow A5, a non-climacteric inodorus, and Charentais C1, a climacteric cantalupensis, regarding the physiological processes related to postharvest quality with a focus on carb...

Integrated COSMO-RS modeling and experimental approach for solvent selection, bioactive recovery and anthocyanin stability from Ilex paraguariensis A.St.-Hil. fruits

Abstract Yerba mate ( Ilex paraguariensis A.St.-Hil.) fruits are underutilized despite their high valorization potential. To address this, the fruits were characterized, phenolic and anthocyanin extraction was optimized, and pigment thermal stability was evaluated. The fruits exh...

Experimental design-based optimization of progesterone-loaded lecithin–chitosan hybrid nanoparticles: ionic self-assembly, colloidal properties, and pH-dependent release

This study reports the experimental design-based optimization of ionic self-assembled lecithin (LC)–chitosan (CS) hybrid nanoparticles using progesterone (PG), a poorly water-soluble lipophilic model drug, to investigate the design-driven development of these nanoparticles. Nanop...

Effects of optimized wheat conditioning on extraction efficiency and milling performance under industrial conditions

Abstract This study aimed to optimize key operational parameters in a commercial flour milling process using U.S. soft white wheat to improve flour yield, moisture, and ash index. A factorial design was employed to evaluate the effects of wheat humidification, conditioning time,...

Climate and dengue synchronization in southern Brazil: a municipal analysis with cross-state validation

Dengue transmission is rapidly expanding beyond its historical tropical range, raising concerns about how climate change may alter the collective dynamics of epidemics. While most studies focus on transmission risk, much less is known about how climate affects the synchronization...
