NITRATE AND PHOSPHATE CONTENTS IN CATFISH SEED REARING PONDS WITH VARIOUS FREQUENCIES OF WATER HYACINTH REPLACEMENT (EICHHORNIA CRASSIPES) [PDF]

Russian Journal of Agricultural and Socio-Economic Sciences, 2020
Nitrate (NO3) and phosphate (PO4) are the main inorganic nutrients required for water hyacinth or eceng gondok (E. crassipes) to grow. Administration of water hyacinth in fish farming activities can intensively improve water quality because water ...

Study on Preparation and Performance of Phosphate Modified Urea Formaldehyde Slow-controlled Release Fertilizer

Guangdong nongye kexue, 2022
【Objective】The nutrient release cycle of urea-formaldehyde (UF) slow-release fertilizer is too long, usually up to 1-2 years, which is not conducive to the full absorption of nutrients by crops.

Non-Linear Prediction Model for the Strength of Medium-to-Low-Grade Phosphate Tailings Cemented Backfill

Applied Sciences
Developing green mining technology for medium-to low-grade mines requires achieving minimal or no damage to the mining area’s ecological environment. A medium-to low-grade phosphate mine in Hubei Province was taken as the research object in this study ...

Co-Doping Effect of Mn²⁺ and Eu³⁺ on Luminescence in Strontiowhitlockite Phosphors

Molecules, 2023
A new series of Sr-based phosphates, Sr9−xMnxEu(PO4)7, were synthesized using the high-temperature solid-state method in air. It was found that these compounds have the same structure as strontiowhitlockite, which is a β-Ca3(PO4)2 (or β-TCP) structure ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Assessment of inorganic nitrogen and phosphorus compounds removal efficiency from different types of wastewater using microalgae cultures

Oceanological and Hydrobiological Studies, 2022
The efficiency of ammonium nitrogen (N-NH4+) and phosphate (P-PO43−) removal from wastewater with different loads of these nutrients was evaluated using Chlamydomonas reinhardtii (Chlorophyta) and Oscillatoria neglecta (Cyanophyta/Cyanoprokaryota).

Hyperphosphatemia and Cardiovascular Disease

Frontiers in Cell and Developmental Biology, 2021
Hyperphosphatemia or even serum phosphate levels within the “normal laboratory range” are highly associated with increased cardiovascular disease risk and mortality in the general population and patients suffering from chronic kidney disease (CKD).

4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase in malaria parasites and enhances atovaquone efficacy

FEBS Letters, EarlyView.
Atovaquone is an antimalarial requiring potentiation for sufficient efficacy. We pursued strategies to enhance its activity, showing that 4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase, decreasing ubiquinone biosynthesis. Since atovaquone competes with ubiquinol in mitochondria, 4‐nitrobenzoate facilitates its action, potentiating ...
