Associations among rearing environment and the infant gut microbiome with early-life neurodevelopment and cognitive development in a nonhuman primate model ().

Early gut microbiome development may impact brain and behavioral development. Using a nonhuman primate model (), we investigated the association between social environments and the gut microbiome on infant neurodevelopment and cognitive function. Infant rhesus monkeys ( = 33) were either mother-peer-reared (MPR) or nursery-reared (NR).

No Effect of Infant Nursery Rearing on Laboratory Rhesus Monkey Dams' Social Behavior or Long-Term Cortisol Profiles.

While the behavioral and physiological impacts of nursery rearing in laboratory-housed infant monkeys have been well characterized, to date no studies have examined the impact on nonhuman primate dams of their infants being removed for rearing in the nursery. Despite the lack of evidence on the topic, anti-animal research groups often cite mother-infant separation and infant nursery rearing (NR) as a welfare concern for laboratory monkey mothers. As such, important policy decisions regarding research activities may result without adequate evidence.

Extraction and improvement of protein functionality using steam explosion pretreatment: advances, challenges, and perspectives.

Protein has become an increasingly valuable food component with high global demand. Consequently, unconventional sources, such as industrial and agroindustrial wastes and by-products, emerge as interesting alternatives to meet this demand, considering the UN Sustainable Development Goals and the transition to a circular economy. In this context, this work presents a review of the use of Steam Explosion (SE), a green technique that can be employed as a pretreatment for various waste materials, including bones, hide/leather, feathers, and wool, aimming the extraction of protein compounds, such as low molecular weight biopeptides, gelatin, and keratin, as well as to enhance the protein functionality of grains and meals.

Whey filtration: a review of products, application, and pretreatment with transglutaminase enzyme.

In the cheese industry, whey, which is rich in lactose and proteins, is underutilized, causing adverse environmental impacts. The fractionation of its components, typically carried out through filtration membranes, faces operational challenges such as membrane fouling, significant protein loss during the process, and extended operating times. These challenges require attention and specific methods for optimization and to increase efficiency.

Techniques and mechanisms of bacteria immobilization on biochar for further environmental and agricultural applications.

Bacteria immobilization on biochar is a promising approach to achieve high concentration and stability of microbial cells for several applications. The present review addressed the techniques utilized for bacteria immobilization on biochar, discussing the mechanisms involved in this process, as well as the further utilization in bioremediation and agriculture. This article presents three immobilization techniques, which vary according to their procedures and conditions, including cell growth, adsorption, and adaptation.
