Researchers test bioartificial liver device to treat acute liver failure Posted: 17 Jul 2015 11:24 AM PDT Researchers have developed and are testing an alternative to liver transplantation called the Spheroid Reservoir Bioartificial Liver that can support healing and regeneration of the injured liver, and improve outcomes and reduce mortality rates for patients with acute liver failure.

Dairy products boost effectiveness of probiotics Posted: 17 Jul 2015 11:24 AM PDT The success of probiotics for boosting human health may depend partly upon the food, beverage, or other material carrying the probiotics, according to research.

Cholesterol metabolism in immune cells linked to HIV progression Posted: 17 Jul 2015 11:24 AM PDT Lower levels of cholesterol in certain immune cells -- a result of enhanced cholesterol metabolism within those cells -- may help explain why some HIV-infected people are able to naturally control disease progression, according to research. The findings provide a basis for potential development of new approaches to control HIV infection by regulating cellular cholesterol metabolism.

Lymphomas tied to metabolic disruption Posted: 17 Jul 2015 11:24 AM PDT Direct links between disrupted metabolism and an often fatal type of lymphoma have been uncovered by researchers.

Researchers, clients turn to video to treat stuttering Posted: 17 Jul 2015 10:10 AM PDT Researchers investigate using self-modelling videos to help clients maintain fluency after treatment. For the study, participant videos were recorded post-treatment when their fluency skills--breathing techniques, how to start their voice, or move forward in speech--were at their peak. Participants were required to watch their videos at least twice a week. And the more they viewed, the better the results were, with a decrease in syllables stuttered and participants reporting their own perceptions that VSM helps in personal and professional situations.

Study in mice may identify new ways to treat immune thrombocytopenia Posted: 17 Jul 2015 09:03 AM PDT A study in mice may identify new ways to treat immune thrombocytopenia. Immune thrombocytopenia, or ITP, is an autoimmune disease whereby the immune system sends antibodies to attack and destroy the body's platelets--blood cells responsible for controlling bleeding.

What are the causes and effects of increased gaming in adolescent girls and boys? Posted: 17 Jul 2015 07:14 AM PDT Technological innovations, multiple genres, online gaming and mobile apps have led gaming to become big business. Call of Duty Black Ops sold 1.4 million copies and registered 2.6 million Xbox Live players on launch day. Adolescents increasingly use gaming for a significant part of their leisure time. New research examines World Health Organization data on adolescent well-being collected from over 4,000 children aged 11-15 to determine why some adolescents gaming habits are escalating. The author reflects on gender, age, policy, parental influences and outcomes for adolescents.

Can cholesterol-lowering drugs help treat acute Ebola cases? Posted: 17 Jul 2015 07:14 AM PDT In the course of basic research in membrane biochemistry scientists have gained new insight into the cytotoxic effect of the Ebola virus. Employing biochemical and cell biological methods they have shed light on the molecular relationships between the Ebola glycoprotein and its role in mediating cytotoxicity. Researchers discovered that the virus glycoprotein interacts with cellular cholesterol, thus prompting the use of certain cholesterol-lowering agents in their investigations. The researchers report they succeeded in suppressing cellular damage in cell cultures.

Moderate hormone suppression may be enough in thyroid cancer, 30-year study shows Posted: 17 Jul 2015 07:14 AM PDT Moderate suppression of thyroid-stimulating hormone, which drives thyroid cancer, may be as beneficial as more extreme hormone suppression, a study of long-term thyroid cancer outcomes shows. Extreme TSH suppression is associated with increased side effects including osteoporosis and heart rhythm irregularities.

Intestinal parasites are common cause of diarrhea in cats: Giardia may be transmitted to humans Posted: 17 Jul 2015 06:21 AM PDT Diarrhea in cats can have several causes, with infections from single-cell intestinal parasites being a common explanation. Researchers studied nearly 300 cats in order to assess the presence and prevalence of parasitic species in Austria. The most common causative agents were Giardia. One species of Giardia that was found may also be transmissible to humans.

Grandparents' affection piling on the pounds in Chinese children Posted: 17 Jul 2015 06:19 AM PDT Affection from grandparents towards their grandchildren may play a major role in contributing to the childhood obesity pandemic in China, new research reveals. Chinese children who are mainly cared for by their grandparents are more than twice as likely to be overweight or obese, compared with those who are mainly looked after by their parents or other adults. Children who are mainly cared for by a grandparent also consume unhealthy snacks and drinks more frequently.

Physicians testified for tobacco companies against plaintiffs with head, neck cancers, study finds Posted: 17 Jul 2015 06:19 AM PDT Despite scientific evidence to the contrary, a small group of otolaryngologists have repeatedly testified, on behalf of the tobacco industry, that heavy smoking did not cause the cancer in cases of dying patients suing for damages, according to a study by a Stanford University School of Medicine researcher.

Toddlers who chill in front of TV are at later risk of being victimized by classmates Posted: 17 Jul 2015 06:19 AM PDT For young children, the number of hours spent watching TV at the age of 29 months correlates to the likelihood he'll be bullied in sixth grade.

Emissions have declined, but sulfur dioxide air pollutant still a concern for asthmatics Posted: 16 Jul 2015 03:09 PM PDT Emissions of the air pollutant sulfur dioxide have been dramatically decreased during the past 30 years but for some people even a little inhaled sulfur dioxide may still be too much.

Drug-encapsulating nanoparticle with bright bio-labels measures how anticancer chemotherapy formulations enter cells Posted: 16 Jul 2015 01:11 PM PDT Polymer nanoparticles that release medicine at controlled rates inside cells have the potential to enhance the efficacy of many clinical drugs. Researchers have now developed an eye-catching way to evaluate the performance of different polymer drug-delivery formulations using luminescent quantum dots as imaging labels.

Repeat infection with malaria parasites might make mosquitoes more dangerous Posted: 16 Jul 2015 01:03 PM PDT In malaria-endemic regions, humans are often infected repeatedly with the Plasmodium parasite. Little is known about possible co-infection and its consequences in the Anopheles mosquitoes that transmit the disease. A new study reports that not only can individual mosquitoes accumulate infections from multiple blood feeds, but also that an existing malaria infection makes mosquitoes more susceptible to a second infection, and that infections reach higher densities when another strain is already present.

Cure for flesh-eating skin disease one step closer Posted: 16 Jul 2015 01:03 PM PDT Scientists have made an important breakthrough in the fight against the flesh-eating tropical skin disease Buruli ulcer, by their discovery that the bacteria causes a blood clot in patients' skin, similar to those that cause deep vein thrombosis (DVT). The new findings mean that, like DVT, the clots may respond to anticoagulant medicines, heal more quickly and with fewer side effects than with antibiotics alone.

New finding on the formation of fat tissue in humans Posted: 16 Jul 2015 09:41 AM PDT Bone marrow contains stem cells that normally give rise to new red and white blood cells. A team of researchers from Sweden and France has now shown that bone marrow cells can also form fat.

Common mental health drug could be used to treat arthritis Posted: 16 Jul 2015 06:17 AM PDT Lithium chloride which is used as a mood stabiliser in the treatment of mental health problems, mainly bipolar disorder, could be used to treat arthritis according to a new study.

Human activities are jeopardizing Earth's natural systems, health of future generations Posted: 15 Jul 2015 06:22 PM PDT A new report calls for immediate, global action to protect the health of human civilization and the natural systems on which it depends. The report provides the first ever comprehensive examination of evidence showing how the health and well-being of future generations is being jeopardized by the unprecedented degradation of the planet's natural resources and ecological systems.
