When people experience stress, the adrenal glands that sit on top of the kidneys release a steroid hormone called cortisol. However, our latest study shows that people who have experienced high levels of trauma in childhood, and who have attempted suicide, tend to release less cortisol when put under stress. These findings build on our earlier work that showed that the stress response system may be "faulty" or "damaged" in people who have recently tried to take their own life.

Mitochondria are microscopic power stations found inside our cells. They convert foodstuffs (nutrients) into fuel, providing our bodies with the energy they need. A new study, published in the journal Acta Neuropathologica, shows that impairment in mitochondria may actually protect the brain in Parkinson's disease.
Regenerative medicine is a broad term used to describe approaches to repair or replace damaged or diseased human cells or tissues. This can be achieved through a variety of approaches, including the use of stem cells and stimulating the body's own repair mechanisms. Due to its wide implications in science, technology, and ethics, regenerative medicine has attracted the attention of a multitude of 'stakeholders' from scientists and physicians to those involved in ethical, legal and social implications (ELSI).
Nonsmoking adolescents who use e-cigarettes, smokeless tobacco or tobacco water pipes are more likely to start smoking conventional cigarettes within a year, according to new research by UC San Francisco.
One of the many difficult things about pancreatic cancer is that tumors are resistant to most treatments because of their unique density and cell composition. However, a new study published in journal Gut found that a three-drug combination can simultaneously target the cancer cells as well as the other harmful, inflammatory cells within the tumor, to improve survival.
According to a new study published in the Journal of Thoracic Oncology, senior patients with stage III non-small cell lung cancer (NSCLC) showed improved overall survival (OS) when treated with chemoradiation (CRT) compared to definitive radiation (RT) alone.
Acute respiratory tract infections (ARTI) are the leading global cause of death in early childhood, according to the Centers for Disease Control and Prevention (CDC). Lower respiratory tract infections, including bronchiolitis and viral and bacterial pneumonia, take a toll on children's health, too, causing the majority of pediatric hospital admissions for infectious diseases.
Regular surfers and bodyboarders are three times more likely to have antibiotic-resistant Escherichia coli in their guts than non-surfers, according to a study published in the journal Environment International.
A new study identifies from a computer model, where the ability to quantify the extent of kidney damage and predict the life remaining in the kidney, using an image obtained at the time when a patient visits the hospital for a kidney biopsy, now is possible using a computer model based on artificial intelligence (AI). These findings appear in the journal Kidney International Reports, can help make predictions at the point-of-care and assist clinical decision-making.
Blood donation is a vital life-saving process but low awareness about the importance of blood donation can impact the safe and adequate supply of blood in hospitals. A research article published in the Update Dental College Journal (UpDCJ) found a positive attitude to blood donation among the donors in Bangladesh but a big disparity between male and female, as well as some knowledge gaps about blood donation.
The study shows Appetite control depends on signaling at the 'primary cilium,' mouse. UC San Francisco researchers have discovered that Primary cilia are distinct from motile cilia, the finger-like projections that act as a sort of cellular conveyer belt, with functions such as removing debris from the lungs and windpipe. This study has published in Nature Genetics.
According to a new study from Weill Cornell Medicine scientists, they identified that Immune cells that process food and bacterial antigens in the intestines control the intestinal population of fungi. Defects in the fungus-fighting abilities of these cells may contribute to some cases of Crohn's disease and other forms of inflammatory bowel disease (IBD). This study has been published in Science.
