Alternative therapies such as aerobic exercise, resistance or strength training and isometric hand grip exercises could help people reduce blood pressure. Biofeedback and device-guided slow breathing reduced blood pressure a small amount. Due to their modest effects, alternative therapies can be...

Brazil is in the midst of an explosion of agricultural production, but who is profiting from that production -- wealthy land owners and investors or average Brazilians is the subject of debate. New research suggests that at least one type of agricultural intensification -- double cropping -- is...

Long-term use of highly active antiretroviral therapies (HAART) does not appear to be associated with impaired heart function in children and adolescents in a study that sought to determine the cardiac effects of prolonged exposure to HAART on children infected with the human immunodeficiency virus...

El patógeno alimentario Listeria monocytogenes es uno de los más virulentos, con una mortalidad que alcanza el 30 %. Ahora, cepas atenuadas de Listeria marcadas con un radioisótopo han logrado eliminar en un 90 % las metástasis del cáncer de páncreas en ratones. Fuente :...

Desde hace años los investigadores trabajan en el desarrollo de terapias eficaces contra la lumbalgia, una dolencia que solo en España supone una media de seis millones de jornadas laborales perdidas cada año. Ahora, expertos de FIK y Tecnalia han creado Lumbia, un dispositivo que podrá utilizarse...

Researchers have tested the effects of partial sleep deprivation on blood vessels and breathing control and found that reducing sleep length over two consecutive nights leads to less healthy vascular function and impaired breathing control. The findings could help explain why sleep deprivation is associated with cardiovascular...

Children can get five to 10 colds each year, so it’s not surprising that adults often turn to over-the-counter cough and cold medicines to relieve their little ones’ symptoms. But a new poll shows that many are giving young kids medicines that they should not use. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/J...
