A healthier start to a pig's life

...tners in Poland. Gramineer International in Sweden produced and purified the lectin, and Lund University tested it in laboratory studies. The Institute of Physiology and Nutrition from the Polish Academy of Science and the Agricultural University of Lublin carried out field studies. Collaborators at the Agric...

Scientists re-grow dental enamel from cultured cells

Dental enamel is the hardest tissue produced by the body. It cannot regenerate itself, because it is formed by a layer of cells that is lost by the time the tooth appears in the mouth. The enamel spends the remainder of its lifetime vulnerable to wear, damage, and decay. For this reason, it is ...

In presence of fragrant cleaning products, air purifiers that emit ozone can dirty the air

Research to spotlight carbon monoxide benefits

...ects. Carbon monoxide causes vasorelaxation and is produced naturally as a result of the breakdown of haemoglobin. This can be seen in the healing process of a bruise, where various colour changes indicate the degradation of haemoglobin and release of carbon monoxide. The slow release of carbon monoxide reduc...

Honeydew honeys are better antioxidants than nectar honeys

...dew have greater antioxidant properties than those produced by bees feeding on nectar. The study is published in this month’s edition of the Journal of the Science of Food and Agriculture. Naturally occurring antioxidants are important ingredients of many foods, and keenly sought in many ‘health foods? They ...

New culture method for hepatitis C virus uses primary hepatocytes and patient serum

...eleased in a cyclical manner, with bursts of virus produced every 10-14 days. This is similar to what has been reported during clinical HCV infection, possibly due to the host's natural defenses. Interestingly, cultured hepatocytes responded to viral replication by displaying signs of distress and cell death...

Killing the messenger RNA -- But which one?

A revolution in the monitoring of unborn babies

...e high risk. The monitor lets doctors read signals produced naturally by the unborn baby’s heart. They can then intervene if necessary and potentially save their lives. The fetal monitor is the result of years of collaborative work between engineers and doctors at the University. The original research was...

Turning a cellular sentinel into a cancer killer

...nd sarcomas. In their experiments, the researchers produced mice whose cells did not have p53 activity. These mice were genetically engineered so that the drug tamoxifen could be used to switch on p53 activity. "When we reactivated p53 in these mice, we saw two distinct tumor phenotypes," said Jacks. "In ly...

Fruit fly gene research may shed light on human disease processes

...s of the proteins encoded on the X chromosomes are produced in each sex. Failure to properly count X chromosomes is lethal to embryos of mammals and flies. That's why biologists want to understand the process of "chromosome counting." Early in his career, Erickson was part of the research team that ident...

A first glimpse of the influenza replication machine

... Interactions (UVHCI)*, both in Grenoble, have now produced the first 3-dimensional image of part of this key protein. The study, which is published in the current issue of Nature Structural and Molecular Biology, investigates the structure and function of the protein and sheds light on how polymerase mutatio...

To solve the mystery, Prof. Benjamin Geiger, Dean of Biology, and Prof. Lia Addadi of the Structural Biology Department, together with doctoral students Chen ...

Widely used iron nanoparticles exhibit toxic effects on neuronal cells

... only one neurite per cell. Additionally, neurites produced in response to the growth factor in the presence of iron oxide nanoparticles were less well formed and also showed abnormal morphology and neurobiological characteristics. The researchers also studied long protein polymers inside the PC12 cells th...

Does a peptide affect the heart's response to social isolation?

...s investigating the effects of oxytocin, a peptide produced by the brain that regulates social behavior, has found that it can prevent detrimental cardiac responses in adult female animals exposed to social isolation. The findings may provide further insight into how these mechanisms affect humans. The stud...
