RVLM C1 Neurons Innervate Sacral as well as Thoracolumbar Autonomic Preganglionic Neurons in the Rat

open access: yesJournal of Comparative Neurology, Volume 534, Issue 2, February 2026.
Axons expressing the adrenaline‐synthesizing enzyme, phenylethanolamine N‐methyltransferase (PNMT), project widely throughout the spinal cord. Many of these axons are from C1 neurons of the rostral ventrolateral medulla. We confirm that dense arrays of PNMT‐expressing, C1‐derived axons surround thoracolumbar sympathetic preganglionic neurons, many of ...

Effect of rice koji levels on the physicochemical and sensory aroma profiles of doenjang

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 3, Page 1734-1743, February 2026.
Abstract BACKGROUND Doenjang, a traditional Korean fermented soybean paste, is often made with rice koji, which provides enzymes and fermentable sugars. However, little is known about how different amounts of rice koji influence fermentation and sensory traits. The present study examined the effects of rice koji levels on the physicochemical, enzymatic

Agricultural System Resilience of Industrial Hemp: An Exploratory Value Web Analysis in the Swabian Alb

open access: yesGCB Bioenergy, Volume 18, Issue 2, February 2026.
This study assessed the industrial hemp value web resilience in the Swabian Alb, Southern Germany, where regional implementation remains limited despite hemp's bioeconomy potential. Using an indicator framework and stakeholder interviews, the research found the small, fluctuating cultivation area (e.g., 25 ha in 2024) focuses on hemp seed valorisation;
