The transition from germinating seeds to emerging seedlings is one of the most vulnerable plant life cycle stages. Heteromorphic diaspores (seed and fruit dispersal units) are an adaptive bet-hedging strategy to cope with spatiotemporally variable environments. While the roles and mechanisms of seedling traits have been studied in monomorphic species, which produce one type of diaspore, very little is known about seedlings in heteromorphic species. Using the dimorphic diaspore model Aethionema arabicum (Brassicaceae), we identified contrasting mechanisms in the germination responses to different temperatures of the mucilaginous seeds (M+ seed morphs), the dispersed indehiscent fruits (IND fruit morphs), and the bare non-mucilaginous M- seeds obtained from IND fruits by pericarp (fruit coat) removal...

BACKGROUND AND OBJECTIVES: Suicidal ideation (SI) during the postpartum phase is linked with suicide, a leading cause of death during this period. Antenatal depression and anxiety symptoms have both been linked with increased risk for postpartum SI. However, research aimed at examining the relative contributions of antenatal anxiety and depression symptoms towards postpartum SI remains nascent. In this study, we investigated the relative contribution of antenatal anxiety symptoms, depression symptoms, and SI towards postpartum SI...

High rates of nonresponse to evidence-based treatment for posttraumatic stress disorder (PTSD) have fueled the search for improved intervention. Evidence suggests that improvements in dispositional mindfulness (i.e., tendency to attend to the present with nonjudgment and nonreactivity) may help reduce PTSD symptoms. While some research suggests that transdiagnostic mindfulness-based interventions particularly target avoidance symptoms, the association between dispositional mindfulness and avoidance has yet to be systematically examined...

Salinity stress in estuarine environments poses a significant challenge for microalgal survival and proliferation. The interaction between microalgae and bacteria shows promise in alleviating the detrimental impacts of salinity stress on microalgae. Our study investigates this interaction by co-cultivating Chlorella sorokiniana, a freshwater microalga, with a marine growth-promoting bacterium Pseudomonas gessardii, both of which were isolated from estuary. In this study, bacteria were encapsulated using sodium alginate microspheres to establish an isolated co-culture system, preventing direct exposure between microalgae and bacteria...

Traumatic exposure can result in acute stress symptoms in the immediate aftermath and post-traumatic stress disorder (PTSD) symptoms that persist beyond the initial weeks. Both short-term and long-term reactions require research and clinical attention. There is considerable evidence for age differences in PTSD, and older adults frequently present lower rates of PTSD compared to young adults. Much less is known concerning age differences in acute reaction or the extent to which age differences in PTSD are affected by age differences in acute stress...

An ever-growing body of literature evidences the protective role of polyhydroxyalkanoates (PHAs) against a plethora of mostly physical stressors in prokaryotic cells. To date, most of the research done involved bacterial strains isolated from habitats not considered to be life-challenging or extremely impacted by abiotic environmental factors. Polar region microorganisms experience a multitude of damaging factors in combinations rarely seen in other of Earth's environments. Therefore, the main objective of this investigation was to examine the role of PHAs in the adaptation of psychrophilic, Arctic-derived bacteria to stress conditions...

Utilizing RNAi, miRNA, siRNA, lncRNA and exploiting genotyping traits can help safeguard the food supply from illnesses and pest damage to Brassicas, as well as reduce yield losses caused by plant pathogens and insect pests. In the natural environment, plants face significant challenges in the form of biotic stress, due to various living organisms, leading to biological stress and a sharp decline in crop yields. To cope with these effects, plants have evolved specialized mechanisms to mitigate these challenges...

Takotsubo cardiomyopathy (TTC) is a rare condition associated with transient akinesia of apical segments and hyperkinesia of basal segments of the heart. Although several mechanisms have been proposed to cause direct and indirect myocardial damage owing to catecholamine excess, the underlying pathophysiology remains unknown. An 18-year-old female was referred to our otorhinolaryngology outpatient clinic for a septorhinoplasty. Apart from the fear of surgery, the patient had no other health issues. After the administration of local anesthesia (lidocaine and epinephrine mix), tachycardia storms occurred and soon ended with cardiac collapse...

Cells can be reprogrammed into senescence to adapt to a variety of stresses, most often affecting the genome integrity. Senescent cells accumulate with age or upon various insults in almost all tissues, and contribute to the development of several age-associated pathologies. Studying the molecular pathways involved in senescence induction, maintenance, or escape is challenged by the heterogeneity in the level of commitment to senescence, and by the pollution of senescent cell populations by proliferating pre- or post-senescent cells...

Astrocytes have been implicated in stress responses and produce ciliary neurotrophic factor (CNTF), which we have shown in the mouse medial amygdala (MeA) to promote passive stress coping response only in females. Pharmacological inhibition of focal adhesion kinase (FAK) upregulates CNTF expression. Here, we found that inducible knockout of FAK in astrocytes or systemic treatment with an FAK inhibitor increased passive coping behavior, i.e., immobility, in an acute forced swim stress test in female, but not male, mice...

When it comes to coping with stress, positive emotion upregulation is of utmost importance. Positive emotions have been suggested to be an important resource during stressful times since people try to create and upregulate pleasant emotional states when feeling stressed. Accordingly, individual differences in the ability to generate and savor positive emotional states could also affect one's skills in dealing with stress. In this regard, an important factor might be depression, which is associated with impaired positive emotion regulation...

The cssR gene ( ncgl1578 ) of Corynebacterium glutamicum encodes a repressor of the TetR (tetracycline regulator) family. Its role in the stress response to antibiotics/heavy metals has been investigated, but how CssR functions in response to phenolic compounds in C. glutamicum has been rarely studied. In this study, we applied transcriptomic analysis, β-galactosidase analysis, qRT-PCR, and EMSAs to analyze the target genes and functions of CssR in response to phenolic compounds. Consistent with the upregulation of genes involved in the degradation of phenolic compounds, the Δ cssR mutant was more resistant to various phenolic compounds than was the wild-type strain...
