Reaction time and intelligence:Comparing associations based on two response modes [PDF]

, 2013
People who score highly on intelligence tests also tend to have faster and less variable reaction times. Effect size estimates for the reaction time-intelligence association are larger in samples that are more representative of the population.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

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

Efficiency of a stirred chemical reaction in a closed vessel

, 2002
We perform a numerical study of the reaction efficiency in a closed vessel. Starting with a little spot of product, we compute the time needed to complete the reaction in the container following an advection-reaction-diffusion process.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Persistent developmental stuttering as a cortical-subcortical dysfunction: evidence from muscle activation Gagueira persistente do desenvolvimento como disfunção córtico-subcortical: evidências pela ativação muscular

Arquivos de Neuro-Psiquiatria, 2008
BACKGROUND: One contemporary view of stuttering posits that speech disfluencies arise from anomalous speech motor control. PURPOSE: To verify the rest muscle tension and speech reaction time of fluent and stuttering adults.
