Optimizing feather hydrolysate via machine learning for microbial recycling of waste concrete fines

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The concrete industry faces significant challenges from CO2 emissions and the disposal of waste concrete fines (WCF). Microbially induced calcite precipitation (MICP) can bind WCF into bioconcrete, but the high cost of commercial culture media hinders its application.

Application of current enteral nutrition support recommendations to infants born less than 750 grams or less than 25 weeks' gestation: A critical review

Journal of Parenteral and Enteral Nutrition, EarlyView.
Abstract Clinicians face a paucity of evidence‐based recommendations for provision of enteral nutrition in infants born <750 g or <25 weeks’ gestation, termed “nano‐preterm.” Current enteral nutrition recommendations for extremely low birth weight infants may not be broadly applicable to nano‐preterm infants due to physiological and developmental ...

Food Security Versus Environmental Health: The Nitrogen Dilemma

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

Biochemical testing and pathology reveal rare cause of pediatric acute liver failure: Hyperornithinemia‐hyperammonemia‐homocitrullinuria syndrome

JPGN Reports, EarlyView.
Abstract Hyperornithinemia‐hyperammonemia‐homocitrullinuria (HHH) syndrome is a rare metabolic condition that can cause lethargy, ataxia, tachypnea, nausea, vomiting, seizures, coma, and acute liver failure. We present a 26‐month‐old female with acute liver failure who was diagnosed with HHH 1 week after admission. Histology revealed an acute hepatitic
