Partial replacement by ammonium nutrition enhances Brassica napus growth by promoting root development, photosynthesis, and nitrogen metabolism.

Nitrogen (N) is crucial for plant growth, available primarily as nitrate (NO) and ammonium (NH). However, its presence in soil is often limited, necessitating strategies to augment N availability. This study delves into the enigmatic interplay between NO and NH in fostering the growth of Brassica napus, an important oil crop worldwide.

Accelerating the Crystallization of Zeolite SSZ-13 with Polyamines.

Tailoring processes of nucleation and growth to achieve desired material properties is a pervasive challenge in synthetic crystallization. In systems where crystals form via nonclassical pathways, engineering materials often requires the controlled assembly and structural evolution of colloidal precursors. In this study, we examine zeolite SSZ-13 crystallization and show that several polyquaternary amines function as efficient accelerants of nucleation, and, in selected cases, tune crystal size by orders of magnitude.

Sodium houttuynia alleviates airway inflammation in asthmatic mice by regulating FoxP3/RORγT expression and reversing Treg/Th17 cell imbalance.

Synthetized from a natural oil of Houttuynia cordata, sodium houttuynia was reported to have anti-inflammatory effects. The present study aimed to investigate whether sodium houttuynia could alleviate the characteristic airway inflammation and Treg/Th17 cell imbalance of asthma in vivo. Experimental mice with neutrophilic asthma were injected with sodium houttuynia or dexamethasone (alone or in combination) intraperitoneally.
