Location and chemical composition of microbially induced phosphorus precipitates in anaerobic and aerobic granular sludge [PDF]

open access: yes, 2012
This work focuses on combined scanning electron microscopy and energy dispersive X-ray analysis (SEM-EDX) applied to granular sludge used for biological treatment of high-strength wastewater effluents. Mineral precipitation is shown to occur in the core

Microbial Indicators for the Efficiency of Disinfection Processes

open access: yesWater Science and Technology, 1986
Fundamental studies have been conducted to find new microbial indicators for the effective inactivation of micro-organisms resistant to disinfectants and UV irradiation. Escherichiacoli, Salmonella typhimurium, Staphylococcusaureus, Candidatropicalis and spore-forming bacteria (isolated from sewage) were exposed to free chlorine or free ozone at ...

Emerging insights into CC and CXC chemokines and their receptors in Mycobacterium tuberculosis infection

open access: yesFEBS Open Bio, EarlyView.
The dual roles of CC and CXC chemokines in distinguishing active, latent, and subclinical tuberculosis were reviewed, along with an evaluation of their potential as diagnostic biomarkers and therapeutic targets to advance precision medicine in tuberculosis management. The graphical abstract was generated with AI assistance (Gemini 3.0).

A case for biotic morphogenesis of coniform stromatolites

open access: yes, 2004
Mathematical models have recently been used to cast doubt on the biotic origin of stromatolites. Here by contrast we propose a biotic model for stromatolite morphogenesis which considers the relationship between upward growth of a phototropic or ...

Assessing the ecological relevance of organic discharge limits for constructed wetlands by means of a model-based analysis [PDF]

open access: yes, 2018
Polder watercourses within agricultural areas are affected by high chemical oxygen demand (COD) and biological oxygen demand (BOD5) concentrations, due to intensive farming activities and runoff. Practical cases have shown that constructed wetlands (CWs)

Natural Products as Geroprotective Modulators in Diabetic Nephropathy: A Mechanistic Framework Integrating Aging Hallmarks and the AMPK–SIRT1–Nrf2 Axis

open access: yesAging and Cancer, EarlyView.
Natural products target the aging kidney in diabetic nephropathy by restoring the AMPK–SIRT1–Nrf2 axis, reducing oxidative stress, inflammation, fibrosis, and cellular senescence while enhancing mitochondrial biogenesis and antioxidant defenses.

Developmental and Epileptic Encephalopathy due to Biallelic Pathogenic Variants in PIGM

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective PIGM encodes a critical enzyme in the glycosylphosphatidylinositol (GPI)‐anchor biosynthesis pathway. While promoter‐region mutations in PIGM have been associated with a relatively mild phenotype characterized by portal vein thrombosis and absence seizures, recent evidence suggests that coding‐region mutations result in a more severe

Antimicrobial use in pigs, broilers and veal calves in Belgium [PDF]

open access: yes, 2014
Given the risks associated with antimicrobial resistance and its link with antimicrobial use, available data on antimicrobial use in the Belgian pig, broiler and veal calf production were compared. Allowing for comparison of the data available from three
