Iron Physiology and Its Impact on Atopic Diseases: An EAACI Taskforce Report

open access: yesAllergy, EarlyView.
ABSTRACT Iron is essential for oxygen transport, energy metabolism, and immune regulation. Yet iron deficiency is the most common micronutrient disorder across all age groups, affecting nearly one quarter of the global population. Iron deficiency triggers nutritional immunity, a host defense mechanism that withholds and redistributes iron, contributing

Phosphorus adsorption and release dynamics in calcareous soil as affected by humic and fulvic acids

open access: yesJournal of Degraded and Mining Lands Management
Humic and fulvic acids play a crucial role in enhancing phosphorus retention in calcareous soils. These organic acids increase phosphorus fixation on soil surfaces, thereby strengthening its binding and modifying its availability in the soil solution ...

Humic Substances from sediments of Lobos Pond (Argentina). Isolation, Characterization and Limnological Implications

open access: yesEclética Química, 2018
Humic substances (HS) were isolated from the sediments of Lobos Pond (Argentina) using mild conditions to preserve their native structure. The HS (humic and fulvic acids) were characterized by means of elemental analysis and FTIR spectroscopy.

The influence of pre-sowing seed treatment by biologically active compounds on soybean seed quality and yield

open access: yesPlant, Soil and Environment, 2016
The aim of the experiment was to improve seed quality of harvested soybean seed by pre-sowing seed treatment with biologically active compounds Lignohumate B (mixture of humic and fulvic acids), Lexin (mixture of humic and fulvic acids enriched by auxins)

Fulvic Acids and Viral Infections

open access: yesThe Open Conference Proceedings Journal, 2012
Fulvic acids are active principles in humic substances allowing big absorption of mineral ions from soil through vegetables. They are formed by large organic molecules having several reactive sites. Tested in mice and rats with radio- active labeled ions ( 45 Ca 2+ , 32 PO4 3- , 59 Fe 3+ and 131 I - ) in drinking water, it has been found that for even ...

Species‐specific processing of fluorescent dissolved organic matter by Caribbean sponges

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Coral reefs are biodiverse and productive ecosystems that are found in typically oligotrophic environments. Many studies have attempted to explain this paradox by demonstrating that microbial symbionts expand metabolic capabilities of host animals.

Direct and indirect photolysis of triclocarban in the presence of dissolved organic matter

open access: yesElementa: Science of the Anthropocene, 2015
Photolysis is an important attenuation pathway for the removal of wastewater effluent organic micropollutants from surface waters. In this work, direct and indirect processes leading to the degradation of the disinfectant, triclocarban were studied ...
