In Spain 62 Percent Of Men And 37 Percent Of Women Over The Age Of 65 Are Sexually Active
A study based on the National Health and Sexuality Survey, involving nearly 2000 people, describes the sexual practices of senior citizens in Spain. The most common are kisses, caresses and vaginal penetration. The main causes of sexual inactivity are physical illness and widowerhood. A new study published in one of the world's biggest sexuality journals the Journal of Sexual Medicine analyses the factors that influence sexual activity amongst elderly people in Spain. "This research lets us know the reality of a social phenomenon which is not tackled enough in Spain: sexuality and the elderly", Domingo Palacios, a researcher at the Rey Juan Carlos University in Madrid and main author of this study, explained to SINC.
A Link Between Atherosclerosis And Autoimmunity
Individuals who suffer from autoimmune diseases also display a tendency to develop atherosclerosis - the condition popularly known as hardening of the arteries. Clinical researchers at LMU, in collaboration with colleagues in WГ rzburg, have now discovered a mechanism which helps to explain the connection between the two types of disorder. The link is provided by a specific class of immune cells called plasmacytoid dendritic cells (pDCs). pDCs respond to DNA released from damaged and dying cells by secreting interferon proteins which stimulate the immune reactions that underlie autoimmune diseases.
Antibody Shrinks Tumors Of Seven Cancers
A single antibody caused tumors from seven different human cancers transplanted into mice to shrink or disappear, according to a new study led by Stanford University School of Medicine in the US. The researchers hope to repeat this dramatic finding with tests in humans within the next two years. Senior author Dr Irving Weissman, professor of pathology at Stanford, and colleagues, write about their success in treating bladder, brain, breast, colon, liver, ovarian, and prostate cancer tumors in this week's online ahead of print issue of the Proceedings of the National Academy of Sciences.
