The Role of Dendritic Spines in Water Exchange Measurements With Diffusion MRI: Double Diffusion Encoding and Free‐Waveform MRI

NMR in Biomedicine, Volume 39, Issue 7, July 2026.
Geometric water exchange in dendritic spines imparts a similar signature on diffusion‐MRI signals as permeative, transmembrane water exchange. Current diffusion MRI methods are non‐specific to geometric and permeative exchange. This work proposes a method to disentangle these two modes of exchange, yielding both more accurate estimates of permeative ...

p,p′-DDE fails to reduce the competitive reproductive fitness in Nigerian male guppies

Ecotoxicology and Environmental Safety, 2006
The ecologically highly important effect of intermale competition is assessed here in a new approach to evaluating endocrine disruption at the population level. A guppy (Poecilia reticulata) male exposed to the antiandrogenic DDT metabolite p,p'-DDE competed against an unexposed male for the opportunity to fertilize a female.

Proposed diagram of p,p′-DDE-induced colorectal adenocarcinoma cell proliferation.

, 2014
At low concentrations, p,p′-DDE promotes colorectal adenocarcinoma cell proliferation through c-Myc and cyclin D1 overexpression resulted from the stimulation of Wnt/β-catenin and Hedgehog/Gli1 signalings, which were mediated by oxidative stress.

Assessment of tissue-specific accumulation, elimination and toxic effects of dichlorodiphenyltrichloroethanes (DDTs) in carp through aquatic food web

Scientific Reports, 2017
Microcosms containing DDT spiked-sediment, Tubifex tubifex and carp (Cyprinus carpio) were constructed to simulate a freshwater system. The accumulation, elimination and toxic effects of DDT (p,p’-DDT, o,p’-DDT), and its metabolites DDD (p,p’-DDD, o,p ...

Advanced control of non‐isothermal axial dispersion tubular reactors with recycle‐induced state delay

The Canadian Journal of Chemical Engineering, Volume 104, Issue 6, Page 3018-3037, June 2026.
Abstract We develop a delay‐aware estimation and control framework for a non‐isothermal axial dispersion tubular reactor modelled as a coupled parabolic‐hyperbolic PDE system with recycle‐induced state delay. The infinite‐dimensional dynamics are preserved without spatial discretization by representing the delay as a transport PDE and adopting a late ...

Alterations in oxidative responses and post-translational modification caused by p,p´-DDE in Mus spretus testes reveal Cys oxidation status in proteins related to cell-redox homeostasis and male fertility [PDF]

, 2018
The major derivate of DDT, 1,1-dichloro-2,2-bis (p-chlorophenyl) ethylene (p,p´-DDE), is a persistent pollutant previously associated with oxidative stress.
