The Role of Stable Bicarbonate Formation on the Loss of Photocatalytic Activity of TiO2 in Grout Media

open access: yesJournal of the Turkish Chemical Society Section B: Chemical Engineering, 2022
In this study, we report the photocatalytic activity of TiO2 monitored by benzene oxidation in the grout medium. The results of the batch reaction tests indicated that the activity of TiO2 coated on grout was substantially less than TiO2 coated on a ...

DNA ligase LigE increases bacterial transformation with damaged extracellular DNA

open access: yesFEBS Letters, EarlyView.
The DNA ligase LigE from the naturally competent Gram‐negative bacterium Neisseria gonorrhoaea increases transformation with cut extracellular DNA. This process is ATP‐dependent and relies on the catalytic activity of LigE; it also requires that LigE contains an intact periplasmic localisation sequence, indicating that ligE functions in the periplasm ...

NAPRT loss promotes lung tumor initiation and growth through AKT signaling independently of NAD+ biosynthesis

open access: yesMolecular Oncology, EarlyView.
Loss of NAPRT promotes lung tumor initiation and growth through a noncanonical mechanism, independent of its role in NAD+ biosynthesis. Mechanistically, NAPRT depletion activates the mTORC2‐driven AKT/β‐catenin signaling axis to enhance clonogenic and invasive phenotypes. Furthermore, lung‐specific Naprt deletion significantly increases tumor burden in

Ménage-à-trois: The ratio of bicarbonate to CO2 and the pH regulate the capacity of neutrophils to form NETs

open access: yesFrontiers in Immunology, 2016
In this study we identified and characterized the potential of a high ratio of bicarbonate to CO2 and a moderately alkaline pH to render neutrophils prone to undergo neutrophil extracellular trap (NET) formation.

Optimization of seminal extracellular vesicle isolation protocols for cancer biomarker analysis using proteomic profiling

open access: yesMolecular Oncology, EarlyView.
This paper shows that size‐exclusion chromatography and sequential centrifugation applied to seminal plasma enrich for different populations of extracellular vesicles. This may significantly affect the detection and analysis of extracellular vesicle‐associated cancer biomarkers.

Land Use Impacts on Water Quality of Rivers draining from Mulanje Mountain: A Case of Ruo River in the Southern Malawi [PDF]

open access: yes, 2014
A research study was carried out to determine the effects of different land uses on the water quality of Ruo River. Water sampling was done both in the upper and the middle sections of the river.

BCG vaccination potentiates oxidative phosphorylation in neonatal myeloid‐derived suppressor cells

open access: yesFEBS Open Bio, EarlyView.
BCG vaccination enhances oxidative phosphorylation in neonatal MDSCs, impairing their immunosuppressive function. It upregulates electron transport chain genes and mitochondrial activity, increasing ATP and oxygen consumption. Pharmacological OXPHOS inhibition partially restores suppressive capacity, confirming causality.

Variability of the PH and of the content of iron assimilable from the soil in the context of the presence of bicarbonates

open access: yes, 2013
In order to study the effect of various species of bicarbonates on the pH and on the content of DTPA-extractable iron, an experiment was organized, showing the effect of 7 progressive concentrations (from 0 to 3%) of ammonium, sodium and potassium ...
