The term 'posttraumatic embitterment disorder' (PTED) was recently introduced to describe a subtype of adjustment disorders, characterized by prolonged embitterment, severe additional psychopathological symptoms and great impairment in most areas of life in reaction to a severe negative but not life threatening life event. The aim of this study is an empirical description and validation of the clinical concept of PTED, by comparing clinically defined PTED patients with patients suffering from other mental disorders on measures of posttraumatic stress and psychopathological distress.

A survey of some of the top hospitals in the country has found that protocols followed to determine brain death differ significantly among those institutions and often do not follow the standards established by the American Academy of Neurology.

Researchers have discovered for the first time a pathway that makes cancerous leukemia cells resistant to treatment. The discovery is the first stage in the development of new drugs that could significantly improve survival rates for leukemia sufferers.

Diet and lifestyle may play a much more significant role in a person's ability to respond favorably to certain drugs, including some cancer therapies, than previously understood, say scientists.

A series of recent scientific publications have exaggerated the benefits and underplayed the harms of drugs to treat pre-osteoporosis or "osteopenia" potentially encouraging treatment in millions of low risk women, warn experts.

Researchers have developed a novel method for producing dark-field x-ray images at wavelengths used in typical medical and industrial imaging equipment. Dark-field images provide more detail than ordinary x-ray radiographs and could be used to diagnose the onset of osteoporosis, breast cancer or Alzheimer's disease, to identify explosives in hand luggage, or to pinpoint hairline cracks or corrosion in functional structures.

Using embryonic stem cells from mice, researchers have prompted the growth of healthy -- and more importantly, functioning -- muscle cells in mice afflicted with a human model of Duchenne muscular dystrophy.

Matters of the mind can affect matters of the heart. A new study has found that major anxiety and/or depression, can double a coronary artery disease patient's chances of repeated heart ailments. This is one of the first studies to focus on patients with stable coronary artery disease -- not those who were hospitalized for events such as a heart attack.

The first genetic dissection of the population structure of European Americans, focusing on identifying the contributions from different genetic ancestries that are important for disease gene mapping has been completed.

Researchers have identified a novel cyclic signaling in the dermis that coordinates stem cell activity and regulates regeneration in large populations of hairs in animal models. The 'dermal clock' signaling coordinates stem cell activity in a population of hair follicles.
