Enhanced adsorption of ammonia and total nitrogen by activated carbon fibres dual-modified with HNO3 and NaOH [PDF]

open access: yesRoyal Society Open Science
Nitrogen serves as an important driver of eutrophication in water bodies, with its excessive inputs posing considerable threats to aquatic ecosystems. In order to remove nitrogen pollutants efficiently, activated carbon fibres (ACFs) were dual-modified ...

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

open access: yesMolecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Dissolved organic nitrogen in the river test and estuary

open access: yes, 2005
Studies of nutrients in rivers and estuaries have generally focused on dissolved inorganic nitrogen (DIN), although this accounts for only a part of the total nitrogen (TN) in these systems.

Patient therapy outcome modeling in cancer organoids is improved by cancer‐associated fibroblasts and organoid assembly convolution

open access: yesMolecular Oncology, EarlyView.
Patient‐derived organoids (PDOs) from pancreatic, colorectal, and gastric cancers were used to evaluate standard and experimental therapies. Incorporating cancer‐associated fibroblasts (CAFs) into organoid cultures improved patient therapy outcome prediction.

Chemiluminescent measurement of total urinary nitrogen for accurate calculation of nitrogen balance

open access: yesClinical Chemistry, 1990
Abstract This instrumental method for total urinary nitrogen (TUN) is based on the principle of gas-phase chemiluminescence. Results correlate well with measurements of TUN by the Kjeldahl method, which has long provided the means to calculate nitrogen balances for nutritional management. In recent years, because of speed and convenience

ZW4864‐mediated inhibition of the β‐catenin/BCL9/BCL9L complex reveals therapeutic potential in bladder cancer

open access: yesMolecular Oncology, EarlyView.
BCL9 and BCL9L drive bladder cancer progression by enhancing β‐catenin signaling, promoting proliferation, migration, invasion, and organoid growth. Genetic depletion of BCL9(L) suppresses malignant phenotypes, while pharmacological disruption of the β‐catenin/BCL9(L) complex with ZW4864 inhibits canonical Wnt signaling and tumor‐associated cellular ...

Predicting Stream Nitrogen Concentration From Watershed Features Using Neural Networks [PDF]

open access: yes, 1999
The present work describes the development and validation of an artificial neural network (ANN) for the purpose of estimating inorganic and total nitrogen concentrations. The ANN approach has been developed and tested using 927 nonpoint source watersheds

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Leaching and uptake of nitrogen, and pasture production, associated with irrigation of treated wastewater, Taupō, New Zealand

open access: yes, 2013
Secondary-treated wastewater from Taupō Township is irrigated onto perennial ryegrass (Lolium perenne) which is harvested and removed from the View Road wastewater treatment site.

Nitrogen fixation by a Bangladesh deepwater rice-field calothrix [PDF]

open access: yes, 1990
In order to study the influence on blue-green algal nitrogenase activity of environmental variables in deepwater rice-fields (DWR), a laboratory study was planned on a DWR isolate of Calothrix (D764).
