Vesicular Trafficking, a Mechanism Controlled by Cascade Activation of Rab Proteins: Focus on Rab27
Biology, 2023 Vesicular trafficking is essential for the cell to internalize useful proteins and soluble substances, for cell signaling or for the degradation of pathogenic elements such as bacteria or viruses.

A SHARP view of H0LiCOW: H0 from three time-delay gravitational lens systems with adaptive optics imaging [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present the measurement of the Hubble constant, H0, with three strong gravitational lens systems. We describe a blind analysis of both PG 1115+080 and HE 0435−1223 as well as an extension of our previous analysis of RXJ 1131−1231.

Assessing brain state and anesthesia level with two-photon calcium signals
Scientific Reports, 2023 Brain states, such as wake, sleep, or different depths of anesthesia are usually assessed using electrophysiological techniques, such as the local field potential (LFP) or the electroencephalogram (EEG), which are ideal signals for detecting activity ...

Cells, 2023 Within the neurovascular unit, brain pericytes (BPs) are of major importance for the induction and maintenance of the properties of the blood-brain barrier (BBB) carried by the brain microvessel endothelial cells (ECs).

Negative refraction makes a perfect lens
Physical Review Letters, 2000 With a conventional lens sharpness of the image is always limited by the wavelength of light. An unconventional alternative to a lens, a slab of negative refractive index material, has the power to focus all Fourier components of a 2D image, even those ...

Cells, 2021 The construction of the blood–brain barrier (BBB), which is a natural barrier for maintaining brain homeostasis, is the result of a meticulous organisation in space and time of cell–cell communication processes between the endothelial cells that carry ...

Extremely low-income households, housing affordability and the Great Recession. [PDF]
, 2017 The effects of the Great Recession on housing equity and homeownership have been well-documented. However, we know little about how rental households fared and the efficacy of housing subsidies in addressing affordability gaps.

Measuring the geography of opportunity [PDF]
, 2016 Quantitative segregation research focuses almost exclusively on the spatial sorting of demographic groups. This research largely ignores the structural characteristics of neighborhoods – such as crime, job accessibility, and school quality – that likely ...

Primary bladder amyloidosis: About a case of incidental discovery
Urology Case Reports, 2021 Primary bladder amyloidosis is rare. Hematuria is the most common form of it's revelation. There are no specific clinical and paraclinical signs to differentiate it from urothelial tumors.

Optics Express, 2018 We propose a single phase-only optical element that transforms different orbital angular momentum (OAM) modes into localized spots at separated angular positions on a transverse plane. We refer to this element as an angular lens since it separates out OAM modes in a manner analogous to how a converging lens separates out transverse wave-vector modes at
