Ivy nanoparticles protect skin from UV radiation better than metal-based sunblocks: Study

When Mingjun Zhang was watching his son play in the yard, he was hit with a burning question: "What makes the ivy in his backyard cling to the fence so tightly?" That simple question has led to a pioneering discovery that the tiny particles secreted from ivy rootlets can be used in many breakthrough applications in items such as military technologies, medical adhesives and drug delivery, and, most recently, sun-block.

Researchers reveal findings on restricted lineage of iPS cells

Adult cells that have been reprogrammed into induced pluripotent stem cells (iPS cells) do not completely let go of their past, perhaps limiting their ability to function as a less controversial alternative to embryonic stem cells for basic research and cell replacement therapies, according to researchers at Children's Hospital Boston, John Hopkins University and their colleagues

Scientists develop new way to increase effectiveness of antiviral drugs

Scientists have developed a new way to target viruses which could increase the effectiveness of antiviral drugs.Instead of attacking the virus itself, the method developed at the University of Edinburgh alters the conditions which viruses need to survive and multiply.

Researchers identify a substance that protects farm children from allergies, allergic asthma

Researchers from Bochum have isolated the substance in cowshed dust that possibly protects farm children from developing allergies and allergic asthma, namely the plant sugar molecule arabinogalactan. If high concentrations thereof are inhaled during the first year of life it inhibits the immune system from excessive defense reactions.

Abbott presents 48-week PROGRESS study results at 28th International AIDS Conference

Abbott today presented 48-week findings comparing an HIV regimen of its protease inhibitor (PI), Kaletra® (lopinavir/ritonavir), and Merck's integrase inhibitor, Isentress® (raltegravir), to a traditional HIV regimen of Kaletra and the nucleotide/nucleoside reverse transcriptase inhibitors (NRTIs) in Truvada® (tenofovir and emtricitabine) in antiretroviral-naive adult patients. Efficacy data were collected over the first 48 weeks of the 96-week PROGRESS (PROtease/InteGRasE Simplification Study) study.

Researchers discover new gene regulation, DNA behavior of breast cancer cells

Cancer researchers have discovered a previously unknown type of gene regulation and DNA behavior in breast cancer cells that may lead to better insight about environmental exposure to estrogen-like compounds. A new study, published in the journal Genome Research by researchers at The Ohio State University Comprehensive Cancer Center-Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC-James), provides the first evidence that cells can regulate many genes at once by looping their DNA, contributing to cancer when it goes awry. In this study, the gene regulation was discovered in breast cancer cells as a response to the hormone estrogen and resulted in the silencing of 14 genes at one time.

Researchers discover genetic explanation for non-diabetic kidney disease in African-Americans

Kidney disease is a growing public health problem, with approximately half a million individuals in the United States requiring dialysis treatments to replace the function of their failed kidneys. The problem is particularly acute among African-Americans, whose rates of kidney disease are four times higher than those of European Americans.
