How mouth cells resist Candida infection

Posted: 02 Sep 2013 07:31 PM PDT

Candida albicans is a common fungus found living in, and on, many parts of the human body. Usually this species causes no harm to humans unless it can breach the body's immune defenses, where can lead to serious illness or death. It is known as an opportunistic pathogen that can colonize and infect individuals with a compromised immune system. New research gives us a greater understanding of how mucosal surfaces in the body respond to C. albicans to prevent damage being done during infection.

Primate calls, like human speech, can help infants form categories

Posted: 02 Sep 2013 01:27 PM PDT

Human infants' responses to the vocalizations of non-human primates shed light on the developmental origin of a crucial link between human language and core cognitive capacities, a new study reports. Previous studies have shown that even in infants too young to speak, listening to human speech supports core cognitive processes, including the formation of object categories. Researchers documented that this link is initially broad enough to include the vocalizations of non-human primates.

Peru: Liver cancer like no other

Posted: 02 Sep 2013 09:39 AM PDT

Liver cancer is the sixth most common cancer worldwide and the third most deadly. It mainly affects men over the age of 40, most often with cirrhosis or hepatitis B or C. But in Peru, it also uncharacteristically affects young people, even children, who do not have the identified related risk factors. Scientists have highlighted a disturbing fact: these patients, with an average age of 25, come from the same geographical area in the Andes.

Health of older women in developed countries continues to improve: Gap with developing countries grows

Posted: 02 Sep 2013 07:20 AM PDT

Measures taken in developed countries to reduce noncommunicable diseases -- the leading causes of death globally -- have improved the life expectancy of women aged 50 years and older over the last 20 to 30 years. But, according to a study the gap in life expectancy between such women in rich and poor countries is growing.

Stomach bacteria switch off human immune defenses to cause disease

Posted: 02 Sep 2013 07:17 AM PDT

Helicobacter pylori is a bacterium that establishes a life-long stomach infection in humans, which in some cases can lead to duodenal ulcers or stomach cancer. New research gives us a clearer understanding of how these bacteria can manipulate the human immune system to survive in the mucosal lining of the stomach.

Robotic IV insertion device means less pain for kids

New test to predict women at risk of pregnancy complications?

Posted: 02 Sep 2013 07:17 AM PDT

Researchers have identified proteins in the blood that could be used to predict whether a woman in her first pregnancy is at increased risk of developing pre-eclampsia. Pre-eclampsia is a complication of pregnancy where the mother develops high blood pressure and protein is present in the urine. In some cases, this can develop into a serious condition for both mother and baby and the only cure is delivery of the baby, often prematurely.

HIV: Predicting treatment response more accurately

Posted: 02 Sep 2013 07:15 AM PDT

HIV is feared, not least, because of its great adaptability. If the virus mutates at precisely the point targeted by a drug, it is able to neutralize the attack and the treatment fails. To minimize these viral defense mechanisms, doctors treat patients with modern combination therapies involving the simultaneous administration of several drugs. This approach forces the virus to run through a series of mutations before it becomes immune to the drugs.

Surprising result: Risk factors for cardiovascular problems found to be inverse to disease and deaths

Posted: 02 Sep 2013 06:56 AM PDT

However, the incidence of serious cardiovascular disease such as heart attacks, strokes, heart failure and deaths followed the opposite pattern: highest in the low income countries, intermediate in middle income countries and lowest in high income countries. Hospitalizations for less severe cardiovascular diseases were highest in the high income countries.
