Psycho-social stress has been suggested to influence the development of cancer, but it remains poorly defined with regard to pancreatic cancer, a lethal malignancy with few effective treatment modalities. In this study, we sought to investigate the impacts of enriched environment (EE) housing, a rodent model of "eustress", on the growth of mouse pancreatic cancer, and to explore the potential u...

OBJECTIVE The purpose of this article is to explore learners' perceptions of using virtual patients in a behavioral medicine Massive Open Online Course (MOOCs) and thereby describe innovative ways of disseminating knowledge in health-related areas. METHODS A 5-week MOOC on behavioral medicine was hosted on the edX platform. The authors developed two branched virtual patients consisting of vid...

Using dill (Anethum graveolens L.) as a model herb, we reveal novel associations between metabolite profile and sensory quality, by integrating non-target metabolomics with data. Low night temperatures exposure to UV-enriched light was used modulate plant metabolism, thereby improving quality. Plant age is crucial factor associated accumulation of ether ?-phellandrene, volatile compounds flavou...

Few would challenge the assertion that the inability to breathe is stressful. In fact, inhaling carbon dioxide to simulate asphyxia is a time-honoured research protocol to unmask panic disorder [1]. Sleep loss is also stressful, as evidenced by increased cortisol and sympathetic tone in insomnia [2] or sleep deprivation [3, 4]. In the case of obstructive sleep apnoea (OSA), impaired breathing e...

Research interest into the exposure of plants to magnetic fields (MF), including electromagnetic (EMF), has increased recently but results often vary depending on factors such as plant species and treatment dose. In this study, we exposed young (one year) old (four years) field bean (Vicia faba L. (partim)) seeds EMF (50 Hz, 7 mT) observed seed germination seedling growth under different condit...

SIGNIFICANCE Plant biologists and microbiologists have long discussed and debated the physiological roles of so-called "redox-active metabolites." These are natural products with unusually high redox activity that are not directly required for active growth. Generally, the biological roles of these compounds have been ascribed to interspecies competition and virulence, and they have been consid...

This paper examines the experience of eustress, using Selye’s (1964, 1987) concept of “good stress”.Usually stress is considered and researched as a negative experience, but we suggest that learning to respond to negative stress and demands with positive emotions and behaviours is likely to increase positive drive, creativity and courage (Le Fevre, Matheny &Kolt, 2003; Selye 1964; 1987). Howeve...

Stress is often described as the result of demands exceeding resources. This is particularly evident in professional careers where women managers balance work, family, and significant travel in addition to their existing repertoire. Women Executives today have to deal with various types of Role Stress which in turn has a negative impact on their Role Efficacy. This paper has explored the types ...

The responses of plants to recurrent stress may differ from their a single event. In this study, we investigated whether clonal can remember past environments. Parental ramets Glechoma longituba (Nakai) Kuprian were exposed UV-B treatments either once or repeatedly (20 and 40 repetitions). Differences in DNA methylation levels growth parameters among parents, offspring genets analysed. Our resu...
