Nutrient solution and substrates for ‘cedro doce’ (Pochota fendleri) seedling production

Revista Brasileira de Engenharia Agrícola e Ambiental
This study assessed the effect of different substrates and addition of nutrient solution on the production of Pochota fendleri seedlings, leaf contents of macro and micronutrients and chlorophyll a and b. The experimental design was completely randomized,

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Potassium Fertigation to Enhance the Performance of Hypoxis hemerocallidea

HortScience, 2021
Potassium (K) is an essential nutrient in plant metabolism, ionic balance, and stress resistance. In this study, the effects of K on agronomic attributes and on mineral and primary metabolite content in African potato were determined.

Uptake of nutrients by lettuce on NFT with controlled composition of the nutrient solution.

Netherlands Journal of Agricultural Science, 1991
An automatically-controlled recirculating NFT system was developed, consisting of a growth unit and a measuring and control unit. It is described together with some basic growth and uptake models. Results are presented of a preliminary experiment with the lettuce cultivar Sitonia (using manual control and nutrient dosage).

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Do NH4:NO3 ratio and harvest time affect celery (Apium graveolens) productivity and product quality?

Folia Horticulturae, 2019
Due to the remarkable health benefits of celery (Apium graveolens), its consumption has increased over time. A partial substitution of NO3− with NH4+ is recommended to limit the accumulation of NO3− in leafy vegetables. Hence, a factorial experiment with
