How do chaperones save protein folding?
Protein folding both in vitro and in vivo goes via formation of intermediate states. These “molten globule”-like states fluctuate, expose their hydrophobic sites and therefore easily aggregate. This retards or even inhibits formation of protein native structures,
Medieval chainmail motif stabilizes DNA nanostructures
The field of nanotechnology refers to all objects in the size range between 1 and 100 nanometers, which correspond to one billionth of a meter. This dimension is hard to imagine and it can be defined as
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.
The antibacterials that have yet to be found
Science has contributed greatly to prolong the lifespan and health conditions of humans. However, close to the coming of age of the XXI Century, humankind is confronting the global war against infectious diseases. Leaving aside other microorganisms-associated
Low salt intake during pregnancy
All cells of an organism share the same DNA sequence from the time they are stem cells until they are fully differentiated, differing greatly in relation to the profile of expressed genes. Changes in gene expression which
Stag beetles restrain bite force to prevent breaking their own jaws
Males have evolved such strong bite muscles, that they risk breaking their own jaws while pinching. They prevent damage by modulating their bite force with a network of tiny sensors in their jaws. The distribution of these
A photothermal optical sensor enables measurement of hemoglobin concentration in unprocessed, nanoliter blood sample
Examining blood sample is like looking over the index of a book on the health of humans. For example, measuring cholesterol concentration in blood enables detection of hyperlipidemia, which is related to pancreatitis and cardiovascular disease, and
Risk modifier(s) of susceptibility to pediatric acute lymphoblastic leukemia
Acute Lymphoblastic Leukemia (ALL) is an acute form of cancer of the white blood cells, characterized by the overproduction and accumulation of immature precursors known as lymphoblasts. ALL is the most common type of leukemia in children
Removal of small tonsils helps children with obstructive sleep apnea
Approximately 2% to 4% of children are affected by obstructive sleep apnea (OSA), a condition that can result in decreased memory, bad grades and behavioral problems in school when it is not treated. Large tonsils and adenoids
How antioxidants may have a pro-oxidant effect?
The main function of the consumption of antioxidants is to strengthen the activity of enzymatic antioxidant systems of our cells and this is intended to prevent or delay oxidative stress caused by the increase of reactive oxygen
