SP and NK1R are highly expressed in brain areas involved in stress responses and drug reward. Studies have also shown that anxiety and stress responses can be reduced in both animals and humans by inactivating NK1R.

Los Angeles, CA (July 1, 2005) -- Cancer cells may be able to avoid destruction by anti-vascular and anti-angiogenesis agents through a cellular stress response that activates a pro-survival protein called GRP78, according to researchers from the Keck School of Medicine of the University of Southern California.See also:Health & MedicineCancerLung CancerBrain TumorColon CancerBreast CancerProstate CancerReferenceHeat shock proteinMetastasisTumor suppressor geneTumorThis provides a novel explanation to address the failure of these drugs to meet initial expectations in the battle against the growth and spread of malignant tumors

he performance pressures from end-of-semester exams and papers can take a toll on students, even leading them to turn to potentially harmful substances to keep them awake and alert.Recent studies show that a growing number of high school and college students are turning to stimulants like ADHD (Attention Deficit Hyperactivity Disorder) drugs and energy drinks to help them through their stress — particularly during exam time, says Jennifer Christner, M.

In a five-year laboratory study, UC surgeon-scientist Karyn Butler, MD, found that when the heart experiences short periods of stress, either from reduced blood flow or high blood pressure, it activates a protective molecular pathway--known as JAK-STAT--that protects the heart muscle. The pathway, which is normally dormant in the heart, was originally identified in disease-fighting white blood cells as a mediator of infection and has recently been targeted for its role in heart health

Both papers explore the role of the stress tests in detecting heart disease.Dobutamine stress echocardiography tests are ultrasound heart scans in which patients are injected with a drug that makes the heart beat faster to determine if they have abnormalities of the heart wall.

When antibody levels were measured four weeks and again 20 weeks later, women in the physical and mental stress groups had more antibodies to the A/Panama flu strain than women in the control group. The exact mechanism of the immunological boost remains unclear, say the authors

Researchers at the School of Sport and Exercise Sciences and the School of Medicine at the University of Birmingham in England asked 60 first-year undergraduate students to answer a battery of questions about their life events, perceived stress, psychological well-being, coping styles, social support and health behaviors. The researchers also took blood samples to measure the concentration of protective meningitis C antibodies in the students.

The findings suggest that there may be persistent differences in the stress response in some trauma-exposed people, even if they do not exhibit PTSD or depression or both, and even if their trauma was years in the past," said Barbara Ganzel, a lecturer in human development in Cornell's College of Human Ecology.Ganzel led a team of Cornell researchers, whose study is published in a the Journal of Traumatic Stress on the biology of trauma.

Scientists at Mount Sinai School of Medicine and the University of Edinburgh studied the relationship between maternal posttraumatic stress syndrome disorder (PTSD) symptoms and salivary cortisol levels in 38 women and their infants. Mothers who experienced symptoms of PTSD in response to 9/11 had lower cortisol levels compared to mothers who did not develop this condition.

ride said that social workers themselves can reduce the likelihood of secondary traumatic stress by finding time for themselves and activities they enjoy. He also recommends that social workers understand which cases are most distressing to them and to schedule those clients so they are not a disproportionate share of their workload

They found that stress-inducing agents, such as oxidative stress, recruit a protein called SENP1 that cuts a regulator called SUMO1 away from the enzyme SIRT1 so its activity level drops, says Dr. Yonghua Yang, postdoctoral fellow in the laboratory of Dr.

The current study is the first to identify the warning signals in humans.For the study, they recruited 22 participants who were suffering from repetitive-stress injuries, including carpal tunnel syndrome, tendonitis, and other wrist and shoulder injuries, and nine healthy subjects.

However, Peter Elias and colleagues at UCSF, have now characterized a mechanistic link in mice between psychological stress and increased susceptibility to skin infections.Mice subjected to conditions of psychological stress were found to be more susceptible to group A Streptococcus pyogenes skin infections than mice housed under normal conditions.
