Heterotrophic Bacteria Isolated from a Chloraminated System Accelerate Chloramine Decay

SSRN Electronic Journal
This work comprehensively demonstrates the ability of heterotrophic bacteria, isolated from a chloraminated system, to decay chloramine. This study non-selectively isolated 62 cultures of heterotrophic bacteria from a water sample (0.002 mg-N/L nitrite and 1.42 mg/L total chlorine) collected from a laboratory-scale reactor system; most of the isolates (

Occurrence of regulated and emerging iodinated DBPs in the Shanghai drinking water.

PLoS ONE, 2013
Drinking water chlorination plays a pivotal role in preventing pathogen contamination against water-borne disease. However, chemical disinfection leads to the formation of halogenated disinfection by products (DBPs). Many DBPs are highly toxic and are of

Evidence of Reactivity in the Membrane for the Unstable Monochloramine during MIMS Analysis

Sensors, 2018
Membrane Inlet Mass Spectrometry (MIMS) was used to analyze monochloramine solutions (NH2Cl) and ammonia solutions in a compact FTICR. Chemical ionization enables identification and quantification of the products present in the permeate. The responses of

Influence of Air Polishing and Ultrasonics on Veneer Margins in Vitro: An Optical Coherence Tomography Pilot Study

Clinical and Experimental Dental Research, Volume 12, Issue 4, August 2026.
ABSTRACT Objective In vitro evaluation of substance loss at the restoration margin of veneers was conducted as a function of prophylaxis procedures, air polishing, or ultrasonic instrumentation. Materials and Methods Forty‐eight extracted premolars were restored with CAD/CAM materials after veneer preparation (t0): lithium disilicate, zirconia ...

A Solvent‐Free Synthesis of Imidazo[1,5‐a]pyridines Using CCl4 as an Oxidant

Journal of Heterocyclic Chemistry, Volume 63, Issue 8, Page 1288-1299, August 2026.
A solvent‐free synthesis of imidazo[1,5‐a]pyridines (Impys) using CCl4 as an oxidant reagent and DBU as the base is informed. An array of Impys derived from different benzylic, heteroaryl aldehydes and others was synthesized in moderate to good yields.

The impact of physiological oxidants on triggering amyloid formation of the cell cycle regulator protein p16INK4A

Protein Science, Volume 35, Issue 8, August 2026.
Abstract The tumor suppressor protein p16INK4a plays a key role in cell cycle control and is frequently inactivated in human cancers. We previously discovered that oxidation of its single cysteine residue induces a structural transition from the functional monomeric form into inactive amyloid fibrils.

Characterisation of the Mesial Root and Middle Mesial Canal Morphology in Mandibular First Molars: An Ex Vivo Micro‐CT Study

Australian Endodontic Journal, Volume 52, Issue 2, Page 364-380, August 2026.
ABSTRACT This ex vivo study characterised the mesial root morphology of mandibular first molars with a middle mesial canal (MMC) using micro‐CT. Among 469 scanned molars, 42 (8.96%) presented an MMC. Morphological parameters analysed included canal configuration, chamber orifice features, dentine thickness, isthmus type, and aspect ratio.
