Nuclear pore links Fob1‐dependent rDNA damage relocation to lifespan control

open access: yesFEBS Open Bio, EarlyView.
Damaged rDNA accumulates at a specific perinuclear interface that couples nucleolar escape with nuclear envelope association. Nuclear pores at this site help inhibit Fob1‐induced rDNA instability. This spatial organization of damage handling supports a functional link between nuclear architecture, rDNA stability, and replicative lifespan in yeast.

Stress hídrico e recuperação em Eucalyptus: perfis fisiológicos

open access: yes, 2012
Mestrado em Biologia AplicadaEm Portugal, cerca de 700,000 ha foram já plantados com clones de Eucalyptus globulus, selecionados pelas suas elevadas taxas de crescimento, alta produção de polpa e adaptabilidade ambiental.

Loneliness, social support and cardiovascular reactivity to laboratory stress [PDF]

open access: yes, 2007
Self-reported or explicit loneliness and social support have been inconsistently associated with cardiovascular reactivity (CVR) to stress. The present study aimed to adapt an implicit measure of loneliness, and use it alongside the measures of explicit ...

Biophysical and biochemical constraints imposed by salt stress:Learning from halophyte

open access: yesFrontiers in Plant Science, 2014
Soil salinization is one of the most important factors impacting plant productivity. About 3.6 billion of the world’s 5.2 billion ha of agricultural dryland have already suffered erosion, degradation and salinization.

PARP inhibitors induce a senescence phenotype in non‐small cell lung carcinoma cell lines

open access: yesFEBS Open Bio, EarlyView.
Talazoparib is the most potent inducer of senescence among different PARP1 inhibitors in human NSCLC cells. In the absence of PARP, no senescence phenotype was observed, demonstrating that PARP1 is necessary for the induction of senescence by this inhibitor.

Nonlinear heart rate variability features for real-life stress detection. Case study : students under stress due to university examination [PDF]

open access: yes, 2011
Background: This study investigates the variations of Heart Rate Variability (HRV) due to a real-life stressor and proposes a classifier based on nonlinear features of HRV for automatic stress detection.

Dynamics in physiological acute stress response trajectories: uncovering latent variability

open access: yesBMC Psychiatry
Background Acute stressors trigger an immediate physiological response, involving multiple intricating pathways. These adaptive physiological responses include, among other processes, an increase in heart rate (HR) and a decrease in heart rate ...

Proteasomal degradation of intracellularly expressed Amblyomin‐X limits suicide gene therapy potential in melanoma cells

open access: yesFEBS Open Bio, EarlyView.
This study explores the feasibility of expressing the antitumoral protein Amblyomin‐X through a suicide gene therapy approach and investigates its intracellular fate after gene delivery. Although the gene is efficiently expressed, melanoma cells rapidly degrade the Amblyomin‐X protein via proteasome activity.
