Nitrification, the oxidation of ammonia via nitrite to nitrate, has always been considered to
be a two-step process catalysed by chemolithoautotrophic microorganisms oxidizing either …

Migraine is a neurovascular disorder that affects over 1 billion people worldwide. Its widespread
prevalence, and associated disability, have a range of negative and substantial effects …

The recent discovery of ammonia-oxidizing archaea (AOA) dramatically changed our perception
of the diversity and evolutionary history of microbes involved in nitrification. In this study, …

Nitrification, the oxidation of ammonia (NH 3 ) via nitrite (NO 2 − ) to nitrate (NO 3 − ), is a key
process of the biogeochemical nitrogen cycle. For decades, ammonia and nitrite oxidation …

A gram-negative, non-motile, non-marine, nitrite-oxidizing bacterium was isolated from an
enrichment culture initiated with a sample from a partially corroded area of an iron pipe of a …

N itrospira are the most widespread and diverse known nitrite‐oxidizing bacteria and key
nitrifiers in natural and engineered ecosystems. Nevertheless, their ecophysiology and …

The cohort of the ammonia‐oxidizing archaea ( AOA ) of the phylum Thaumarchaeota is a
diverse, widespread and functionally important group of microorganisms in many ecosystems. …

Geothermal environments are a suitable habitat for nitrifying microorganisms. Conventional
and molecular techniques indicated that chemolithoautotrophic nitrite-oxidizing bacteria …

Background Direct comparisons of the tolerability and safety of migraine preventive treatments
targeting the calcitonin gene-related peptide pathway are lacking. This study aimed to …

Objective: For 3,670 stroke patients from the United Kingdom, United States, Australia,
Belgium, and Italy, we performed a genome-wide meta-analysis of white matter hyperintensity …
