A joint Argentinian-French study suggests that elastic stresses may play a crucial role in determining leaf venation patterns. By developing a numerical model, the researchers found simulated patterns with statistical properties similar to natural ones, challenging the existing view of auxin's role in vein formation.
A Review in The Lancet emphasizes the importance of a healthy lifestyle in reducing stress to manage risk factors associated with adverse cardiovascular outcomes. Studies have shown that both acute and chronic stressors can increase the risk of cardiac events, with major life changes and emotional stressors being key contributors.
A study of 279 torture survivors found that psychological manipulation, deprivation, and humiliation caused as much distress as physical torture. The researchers concluded that the distinction between torture and other forms of maltreatment is not only useless but also dangerous.
Humans and primates are highly intelligent, social creatures prone to stress-related diseases due to chronically psychosocially stressed situations. Chronic stress compromises health by suppressing immune function, reproduction, and brain function.
Researchers found that cortisol can lessen emotional impact of stress in women, with a high dose providing protective effects. The study suggests potential for cortisol as a clinical tool to treat and prevent anxiety disorders.
A study of 562 young students found that girls experienced more depressive symptoms and stressors than boys, particularly in their interpersonal world. The researchers discovered that exposure to stressors and the way girls reacted to these events contributed to their higher levels of depression.
Researchers found that experiencing control over a stressor immunizes a rat from developing depression-like syndrome when it later encounters uncontrollable stressors. The prefrontal cortex plays a crucial role in processing information about controllability and regulating responses to subsequent stressors.
Researchers studied 100 patients and found symptoms recurred in 11% of patients, with physical stressors linked to worse survival rates. Abnormalities in small blood vessels may contribute to the condition.
Rugby players from the UK and Ireland reported stressors such as injury, mental errors, and physical mistakes as a major concern. They found effective coping strategies like increased concentration, blocking negative thoughts, and positive self-talk to manage these stressors.
Researchers found that isolated female rats subjected to a 30-minute stressor recover more quickly and mount a stronger immune response than male counterparts. This difference may be related to the demands of motherhood, which has evolved to provide females with protection against trauma.
Researchers investigated how parents influence adolescents' coping mechanisms for stress. Secure parent-child relationships are associated with the development of adaptive coping styles, which can lead to long-term positive outcomes. In contrast, insecure relationships may result in maladaptive coping strategies that increase distress.
Chronic exposure to discrimination may increase the risk of cardiovascular disease in African-American women, according to a study. The research found that higher levels of perceived discrimination were associated with greater calcium buildup in the arteries, highlighting the importance of addressing this stressor for heart health.
A study by Texas A&M University psychologist David H. Rosen found that watching a comedy video significantly increased participants' scores for hopefulness. The finding suggests humor can be a legitimate strategy for relieving stress and maintaining well-being while increasing hope.
The University of Ulster team found significantly increased levels of stress on two fault zones in Indonesia, including the Sunda trench and Sumatra fault. The analysis suggests a high risk of another earthquake, potentially triggering another tsunami.
A study by University of Colorado researchers found that rats with controlled stress exhibit reduced brainstem activation and behaviors similar to depression and anxiety. The prefrontal cortex sends inhibitory signals to the brainstem when stress is controllable, quelling alarm center activity.
A meta-analysis of 293 studies found that stress affects immunity in distinct ways, with short-term stress boosting natural immunity but chronic stress weakening it. Chronic stress is particularly damaging, especially for older or sick individuals, while acute time-limited stressors enhance quick energy-efficient responses.
A study found that less educated individuals face higher daily stress levels, which have more significant negative impacts on their health. The researchers discovered that daily stressors vary by socio-economic status, with those in disadvantaged positions experiencing greater health downturns.
A new study by Dr Stephen Joseph finds that emergency personnel in Northern Ireland experience high levels of psychological distress due to lack of control over their lives. Effective coping skills like anger management, emotional disclosure, and relaxation training can aid recovery from traumatic incidents.
Researchers found that individuals with two copies of the met form of the COMT gene had a more pronounced response to pain, while those with two copies of the val form reported less pain and fewer negative emotions. The study used PET brain imaging and controlled jaw pain to investigate the role of genetic variation in pain tolerance.
A new study suggests that Alzheimer caregivers' chronic stress may trigger excessive blood clotting, increasing the risk of coronary events such as heart attacks. The research found that high levels of stress were associated with higher fibrin D-dimer levels, even within normal ranges.
Researchers are studying 200 families in Baltimore to understand how children aged 9-14 are impacted when a parent loses their job. The study aims to identify coping mechanisms that can help prevent negative behavior and emotional problems, and will inform prevention programs to reduce stress.
Researchers found that recalling stressful events can lead to delayed blood pressure recovery and increased cardiovascular disease risk. Chronic stress is also associated with an elevated risk of later heart disease, likely due to prolonged strain on the cardiovascular system.
Research found that alcoholics exhibit blunted heart-rate responses to public speaking despite similar anxiety levels, indicating a disconnection between perception and physiological response. This impairment may contribute to social functioning and emotional experiences in individuals recovering from severe alcohol dependence.
Researchers at Ohio State University found a link between major stressors during pregnancy and the development of autism in children. The study, which included over 200 mothers, showed that stress levels for mothers of autistic children were nearly twice those of other mothers.
A study found that socially stressed mice were twice as likely to die after infection with a compound than physically stressed mice. The researchers believe social stress intensified the immune response, leading to toxic shock and organ damage.
New research reveals that uncontrollable stresses can severely affect the immune system by disrupting cytokine function and producing high levels of cortisol. In contrast, controlled stress responses result in brief, insignificant changes to immune activity.
