What predicts who will do well in treatment for post-traumatic stress disorder?

Post-traumatic stress disorder (PTSD) is a common psychological response following a traumatic event and affects about 8% of the population. Effective psychological treatments do exist and should be made available to anyone who is diagnosed with PTSD.

With a little help from friends: how plastids aid the ER to deal with misfolded proteins

Almost a third of all proteins in eukaryotic cells are synthesized and folded in the endoplasmic reticulum (ER) before being secreted and redistributed to other organelles, such as the Golgi apparatus, lysosomes, and the plasma membrane. To

Do Bucentaur family proteins represent true monsters in the fight against stress?

The BCNT (Bucentaur) protein family, which is conserved from fungi to humans, is classified by the presence of an ~80 amino acid sequence at the C-terminus called BCNT-C. Family members in fungi, flies, fish, and chicken play

“Chemobrain” prior to cancer treatment? The cause is probably cancer-related post-traumatic stress

Mothers of children with autism report worse immunity

Increased stress hormone exposure can be beneficial

Under challenging circumstances, such as predator exposure or lack of food, animals naturally secrete stress hormones. Production, secretion and release into the bloodstream of these hormones is tightly regulated by the Hypothalamic-Pituitary-Adrenal axis (the stress axis), a

ER stress: a new molecular target to treat hyperglycemia-induced vascular damage

Endothelium is a thin layer of cells, which covers the inner surface of blood vessels and has a key role in the maintenance of vascular and metabolic homeostasis. Its functions include regulation of vascular tone, inhibition of

A variant RNA polymerase controls bacterial pathogenicity and stress responses

In order for cells to carry out normal functions, the genetic information stored in DNA needs to be first converted to RNA. This conversion – known as transcription – is carried out by a class of enzymes

A gentle look at the heart

Coronary artery disease is one of the major causes of death in the Western population, mainly because of the potential risk of a heart attack. The latter often occurs out of the blue and the only chance

The role of light and hormones in seed germination under environmental stress

Environmental factors such as light, temperature, water and gravity have major effects on plant development. In addition, hormones within the plant bring about developmental changes during the plant life cycle. Extensive crosstalk exists between environmental and hormone
