New technique overcomes genetic cause of infertility

Scientists have created healthy offspring from genetically infertile male mice, offering a potential new approach to tackling a common genetic cause of human infertility. Our sex is determined by the X and Y chromosomes. Usually, girls have two X chromosomes (XX) and boys have one X and one Y (XY), but approximately 1 in 500 [...]

Heart failure patients, clinicians have differing perceptions of risk level

Physicians identified a majority of patients with advanced heart failure as at high risk for transplant, left ventricular assist device (LVAD) or death while few of those patients considered themselves to be at high risk, according to a study published today in JACC: Heart Failure. Physicians rated 161 patients for perceived risk for transplant, LVAD or [...]

Are stem cells the link between bacteria and cancer?

Gastric carcinoma is one of the most common causes of cancer-related deaths, primarily because most patients present at an advanced stage of the disease. The main cause of this cancer is the bacterium Helicobacter pylori, which chronically infects around half of all humans. However, unlike tumour viruses, bacteria do not deposit transforming genes in their host [...]

Reduced kidney function linked to an increased risk of community-acquired infections

Individuals with reduced kidney function may be at increased risk of developing infections acquired in the community, according to a study appearing in an issue of the Clinical Journal of the American Society of Nephrology (CJASN). The findings indicate that people with kidney disease would benefit from an increased focus on preventing infections. Infections contracted outside [...]

Pioneering research reveals how altered brain networks can lead to seizures

An international team of scientists, led by mathematicians from the University of Exeter’s Living Systems Institute, have developed a ground-breaking new method that can identify regions of brain tissue most likely to generate seizures in people with epilepsy. The innovative new method, which utilizes mathematical modelling, offers the potential to complement existing clinical approaches and [...]
