STAT3 expression is reduced in cardiac pericytes in HFpEF and its loss reduces cellular adhesion and induces pericyte senescence

open access: yesFEBS Letters, EarlyView.
Heart failure with preserved ejection fraction (HFpEF) accounts for half of the heart failure cases. It is characterised by microvascular dysfunction, associated with reduced pericyte coverage and diminished STAT3 expression in pericytes. Loss of STAT3 impairs pericyte adhesion, promotes senescence, and activates a pro‐fibrotic gene program.

Interstellar Extinction in the Direction of The Barnard 1 Dark Cloud in Perseus

open access: yesOpen Astronomy, 2003
Spectral and luminosity classes, absolute magnitudes, color excesses, interstellar extinctions and distances are determined for 98 stars down to 18 mag in the Barnard 1 dark cloud belonging to the Per OB2 association. The classification of stars is based

The Vector Equivalence Technique [PDF]

open access: yesarXiv, 1992
We present the Vector Equivalence technique. This technique allows a simple and systematic calculating of Feynman diagrams involving massive fermions at the matrix element level. As its name suggests, the technique allows two Lorentz four-vectors to serve as an equivalent of two external fermions. In further calculations, traces involving these vectors

THE TECHNIQUE OF RETINOSCOPY. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1898
It is only within the past ten years that the value of retinoscopy as an objective test in the estimation of errors of refraction, has been fully recognized. The fact that, after a little practice, the kind and amount of refractive error can be ascertained quickly, accurately and independently of the patient, has made it deservedly popular.

Protonophore activity of short‐chain fatty acids induces their intracellular accumulation and acidification

open access: yesFEBS Letters, EarlyView.
The protonated form of butyrate, as well as other short‐chain fatty acids (SCFAs), is membrane permeable. In acidic extracellular environments, this can lead to intracellular accumulation of SCFAs and cytosolic acidification. This phenomenon will be particularly relevant in acidic environments such as the large intestine or tumor microenvironments ...

OGM ET DEBAT PUBLIC OGM : avancée ou recul de la sécurité alimentaire ?

open access: yesOléagineux, Corps gras, Lipides, 2001
Les nouvelles technologies de manipulation génétique ont été présentées par certaines entreprises comme une opportunité pour l’humanité d’en finir avec la malnutrition, grâce au développement de la production agricole que cela pouvait entraîner. Le débat

Three Holy Men Get Haircuts: The Semiotic Analysis of a Joke

open access: yesEurope's Journal of Psychology, 2016
This article deals with a typology of 45 techniques of humor that I found when doing research on the mechanisms that generate humor in texts, lists the techniques and applies them to a Jewish joke. It references the work of Vladimir Propp on folktales as

Smooth, Efficient, and Interruptible Zooming and Panning [PDF]

open access: yesarXiv, 2018
This paper introduces a novel technique for smooth and efficient zooming and panning based on dynamical systems in hyperbolic space. Unlike the technique of van Wijk and Nuij, the animations produced by our technique are smooth at the endpoints and when interrupted by a change of target.

Unlocking the potential of tumor‐derived DNA in urine for cancer detection: methodological challenges and opportunities

open access: yesMolecular Oncology, EarlyView.
Urine is a rich source of biomarkers for cancer detection. Tumor‐derived material is released into the bloodstream and transported to the urine. Urine can easily be collected from individuals, allowing non‐invasive cancer detection. This review discusses the rationale behind urine‐based cancer detection and its potential for cancer diagnostics ...
