Laboratório de Extração, Termodinâmica Aplicada e Equilíbrio - EXTRAE, Faculdade de Engenharia de Alimentos, Universidade Estadual de Campinas, Rua Monteiro Lobato,80, 13083-062 Campinas, SP, Brazil. Electronic address:

Soy extract waste, okara, is a rich source of bioactive compounds such as isoflavones, which are phytoestrogens with potential health benefits. To develop a green approach to recovering these compounds and valorizing okara, a study was developed to screen variables for the extraction of isoflavones from okara and soybean (for comparison) using Deep Eutectic Solvents (DES) composed with choline chloride ([Ch]Cl) and acetic acid (AA) ([Ch]Cl: AA, 1:2). A fractional design (2) was used to evaluate variables in the extraction of isoflavones, followed by a Central Composite Rotatable Design (CCRD).

There has been a rising call to decolonize global health so that it more fully includes the concerns, knowledge, and research from people all over the world. This endeavor can only succeed, we argue, if we also recognize that much of established global health doctrine is rooted in Euro-American beliefs, values, and practice rather than being culturally neutral. This paper examines the cultural biases of child feeding recommendations as a case in point.

Identification of candidate genes involved in Zika virus-induced reversible paralysis of mice.

Sci Rep

January 2025

Institute for Antiviral Research, Department of Animal, Dairy, and Veterinary Sciences, Utah State University, Logan, UT, 84321-5600, USA.

Zika virus (ZIKV) causes a variety of peripheral and central nervous system complications leading to neurological symptoms such as limb weakness. We used a mouse model to identify candidate genes potentially involved in causation or recovery from ZIKV-induced acute flaccid paralysis. Using Zikv and Chat chromogenic and fluorescence in situ RNA hybridization, electron microscopy, immunohistochemistry, and ZIKV RT-qPCR, we determined that some paralyzed mice had infected motor neurons, but motor neurons are not reduced in number and the infection was not present in all paralyzed mice; hence infection of motor neurons were not strongly correlated with paralysis.
