Cracking the Nut [PDF]

open access: yesToxicological Sciences, 2004
Phthalate esters impart flexibility to hard plastics, are used as inert ingredients in cosmetics and personal hygiene products, and are ubiquitous environmental contaminants. Finding the underlying molecular mechanism of phthalate-induced testicular injury has been a vision quest of male reproductive toxicologists for many decades.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Cracking the system [PDF]

open access: yesBritish Journal of General Practice, 2008
I took a moment to listen to his breathing. My heart sank. Even without the aid of a stethoscope, it sounded like stridor and, given his age and past smoking, a bronchial carcinoma until proven otherwise. It had not been an easy trip for my Dad who, accompanied by Mum, had fallen through the system when their first connecting flight from Glasgow had ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Investigating diverse photogrammetric techniques in the hazard assessment of historical sites of the Museum of the Coal Basin Area in Będzin, Poland

open access: yesReports on Geodesy and Geoinformatics
Assessing the condition of historical sites at risk requires an interdisciplinary approach based on combining multiple measurement technologies. Due to the dynamic development of technology, non-invasive remote sensing methods are gaining significant ...

Discourses and Cracks [PDF]

open access: yes, 2000
This paper discusses information technology as political and practical discourse. This repetitive discursive model can be distinguished in global, regional and local contexts and contains an optimistic belief in technology as an independent power that automatically furthers democratic development.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

open access: yesFEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...
