FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

On the Slow-Time k-Space and its Augmentation in Doppler Radar Tomography
Sensors, 2020 Doppler Radar Tomography (DRT) relies on spatial diversity from rotational motion of a target rather than spectral diversity from wide bandwidth signals.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Psicologia: Reflexão e Crítica, 2006 O objetivo deste trabalho foi investigar a função de sensibilidade ao contraste (FSC) de adultos e idosos (20-23, 30-39, 40-49, 50-59, 60-69 anos) para grades senoidais de 0,25 a 2 cpg em luminância baixa.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Psicologia: Reflexão e Crítica, 2006 The aim of this work was to investigate the contrast sensitivity function for sine-wave gratings in the range between 0.25-2 cpd in young and older adults (20-23, 30-39, 40-49, 50-59, 60-69 years old) using low luminance.

Frontiers in Psychology, 2019 Interpreting another’s true emotion is important for social communication, even in the face of deceptive facial cues. Because spatial frequency components provide important clues for recognizing facial expressions, we investigated how we use spatial ...

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

On spatial-frequency channels [PDF]
Perception & Psychophysics, 1984 Inan effort to explain the role ofspatial frequency channels in vision, there have been many suggestions, notably by Julesz (1975, 1980; Julesz & Schumer, 1981),Levinson and Frome (Frome, Levinson, Danielson, C Levinson & Frome, 1979), andBraddickand Atkinson (1982), linking them to attention.This idea seems very reasonable in view ofthe fact thatthe
