background : breast cancer is one of the most frequent malignancies among iranian women. these patients suffer from a wide range of physical and mental (depression, anxiety and stress) signs and symptoms during the diagnostic and therapeutic processes. despite the improvement in survival rates due to advances in medical care, different types of psychosocial interventions are still growingly nee...

Background and Aim: Post-Traumatic Stress Disorder is one of the anxiety disorders which occur in postpartum period. The prevalence of PTSD – induced by preeclampsia has been already reported as 28%, however no study was found to compare PTSD in primiparous and multiparous women. This study was therefore conducted to compare PTSD in primiparous and multiparous women. Methods: This comparative d...

The complex integrity of the cells and its sudden, but often predictable changes can be described and understood by the topology and dynamism of cellular networks. All these networks undergo both local and global rearrangements during stress and development of diseases. Here, we illustrate this by showing the stress-induced structural rearrangement of the yeast protein-protein interaction netwo...

Transcription factors play key roles in plant development and stress responses through their interaction with cis-elements and/or other transcription factors. Homeodomain associated leucine zipper proteins (HD-Zip) constitute a family of transcription factors that are characterized by the presence of a DNAbinding domain closely linked with leucine zipper motif functioning in dimer formation. Th...

Calorie restriction (CR) without malnutrition is the most robust intervention to slow aging and extend healthy lifespan in experimental model organisms. Several metabolic and molecular adaptations have been hypothesized to play a role in mediating the anti-aging effects of CR, including enhanced stress resistance, reduced oxidative stress and several neuroendocrine modifications. However, littl...

Stress can compromise an animal's ability to conserve metabolic stores and participate in energy-demanding activities that are critical for fitness. Understanding how wild animals, especially those already experiencing physiological extremes (e.g. fasting), regulate stress responses is critical for evaluating the impacts of anthropogenic disturbance on physiology and fitness, key challenges for...

HIGHLIGHTS The PRC2 interacting protein BLISTER likely acts downstream of PRC2 to silence Polycomb target genes and is a key regulator of specific stress responses in Arabidopsis. Polycomb group (PcG) proteins are key epigenetic regulators of development. The highly conserved Polycomb repressive complex 2 (PRC2) represses thousands of target genes by trimethylating H3K27 (H3K27me3). Plant speci...

vicia sativa l., an annual winter growing leguminous plant, is a valuable source of protein and minerals for cattle. drought is one of the key stress factors that influence plant growth and development. in order to investigate common vetch physiological and molecular responses under normal irrigation (n) and two levels of drought stress [s1= 30% and s2= 10% field capacity (fc)], a greenhouse exp...
