Consumption of ammonia-nitrogen by aob in immobilized batch culture

Journal of Fundamental and Applied Sciences, 2018
This study investigated the performance of bio-filters immobilized nitrifying bacteria, ammonia oxidizing bacteria (AOB) and nitrite oxidizing bacteria (NOB). In particular, it wasto assess the consumption of ammonia-nitrogen (NH3-N) by the AOB. The experiment wasconducted in a one litre reactor.The reactor consisted of bio-filters with NH3-N as ...

But how does it smell? An investigation of olfactory bulb size among living and fossil primates and other euarchontoglirans

The Anatomical Record, Volume 309, Issue 4, Page 1037-1060, April 2026.
Analysis of cranial endocast data of 181 extant and 41 fossil species from Euarchontoglires shows that there was a reduction in olfactory bulb size in Crown Primates, but that there were also subsequent reductions in various other primate clades (Anthropoidea, Catarrhini, Platyrrhini, crown Cercopithecoidea, Hominoidea).

Impact of Fire and Heat Stress on Soil Microorganisms: A Review of Community Changes, Molecular Responses and Plant‐Beneficial Roles

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This work reviewed the direct and indirect effects of fires on microbial communities and the resilience strategies microbes use to withstand high temperatures . ABSTRACT Fire, whether occurring on the surface or underground, significantly influences soil microbial dynamics by reshaping community composition, functional diversity and overall soil and ...

Rhizobial motility preference in root colonization of Medicago truncatula

New Phytologist, Volume 250, Issue 1, Page 547-562, April 2026.
Summary Tunnel‐like infection thread (IT) structures support root colonization by symbiotic nitrogen‐fixing rhizobia bacteria in most legume species. These tip‐grown structures are key to directing rhizobia from root hairs to developing nodules, where they are hosted to fix nitrogen.

Transposition and Intermingling of Galphai2 and Galphao afferences into single vomeronasal glomeruli in the Madagascan lesser Tenrec Echinops telfairi.

PLoS ONE, 2009
The vomeronasal system (VNS) mediates pheromonal communication in mammals. From the vomeronasal organ, two populations of sensory neurons, expressing either Galphai2 or Galphao proteins, send projections that end in glomeruli distributed either at the ...

Core Epithelial‐to‐Mesenchymal Transition Gene Signature Predicts Metastasis and Poor Survival in Synovial Sarcoma

Cancer Medicine, Volume 15, Issue 3, March 2026.
ABSTRACT Background Synovial sarcoma (SS) is a rare soft tissue malignancy comprising 5%–10% of all sarcomas, typically affecting young adults. It is characterized by a pathognomonic SS18–SSX gene fusion, with variable histologic subtypes demonstrating epithelial and mesenchymal features.
