Cancer concerns over chromium diet pills

Concerns have been raised over the long-term use of nutritional supplements containing chromium, after an Australian research team found the supplement is partially converted into a carcinogenic form when it enters cells.

Researchers describe three cleaning procedures that effectively remove, disassemble α-Syn fibrils

Lewy bodies and Lewy neurites are found in the brains of Parkinson's disease (PD) patients. They consist primarily of fibrils of the protein alpha-synuclein (α-Syn), which self-assembles into fibrils in vitro. If introduced into the human body, these seeds can act as prions and trigger the formation of toxic protein deposits. Because α-Syn fibrils are often used in research, it is important that they are not accidentally transferred to humans or cell cultures.

DNA-binding protein acts like genetic traffic signal to orchestrate early stage embryonic development

New research by UC San Francisco stem cell biologists has revealed that a DNA-binding protein called Foxd3 acts like a genetic traffic signal, holding that ball of undifferentiated cells in a state of readiness for its great transformation in the third week of development.

Experts develop technologies for protecting drinking water

We place high demands on the quality of our drinking water. If pathogens or toxic substances found their way into the piping system, many people could become infected or injured very quickly. That's why this risk must be kept low. To do this, experts have developed technologies for a comprehensive monitoring, early warning and emergency management system.

New injectable agent can potentially increase surgeon's ability to remove cancerous tumor during surgery

Doctors at the Duke University School of Medicine have tested a new injectable agent that causes cancer cells in a tumor to fluoresce, potentially increasing a surgeon's ability to locate and remove all of a cancerous tumor on the first attempt. The imaging technology was developed through collaboration with scientists at Duke, the Massachusetts Institute of Technology and Lumicell Inc.

Researchers identify mechanism that allows cancer cells to grow rapidly when blood sugar levels rise

Researchers have identified a mechanism that allows cancer cells to respond and grow rapidly when levels of sugar in the blood rise. This may help to explain why people who develop conditions in which they have chronically high sugar levels in their blood, such as obesity, also have an increased risk of developing certain types of cancer.

Lipoprotein nanoplatelets important for imaging biological molecules and cells

An interdisciplinary research team from the University of Illinois at Urbana-Champaign has developed a new material composite derived from quantum dots. These lipoprotein nanoplatelets are rapidly taken up by cells and retain their fluorescence, making them particularly well-suited for imaging cells and understanding disease mechanisms.

New report raises questions about potential risks of chromium therapies

Chromium supplements are widely consumed for their antidiabetic activity as chromium(III) enhances the insulin sensitivity of cells. In particular, orthomolecular practitioners believe in the beneficial effects of providing the body with extra amounts of essential trace elements.

Fraunhofer scientists use antibodies to detect cancer cells in tissue samples

Antibodies combat viruses and bacteria. They also attach themselves to cancer cells - in a typical, characteristic way. Fraunhofer scientists are using this property to detect cancer cells in tissue samples. Such rapid tests can already be applied by surgeons during operations - within a few minutes and without expensive equipment.

3-D recordings of nematode brains may help understand how neurons coordinate action and perception

Princeton University researchers have captured among the first recordings of neural activity in nearly the entire brain of a free-moving animal. The three-dimensional recordings could provide scientists with a better understanding of how neurons coordinate action and perception in animals.

Researchers use dynamic time-series data to help improve accuracy of genome mapping

If you already have the sequenced map of an organism's genome but want to look for structural oddities in a sample, you can check the genomic barcode -- a series of distances between known, targeted sites -- by cutting a DNA sequence at those sites and examining the distance between the cuts.

New model provides images of single cell with micrometer resolution

Thermal properties of cells regulate their ability to store, transport or exchange heat with their environment. So gaining control of these properties is of great interest for optimizing cryopreservation -- the process of freezing and storing blood or tissues, which is also used when transporting organs for transplants.

Microencapsulation method can help overcome challenges in pancreatic islet transplantation

A microencapsulation method, developed by OIST researchers, can help to overcome major challenges in pancreatic islet transplantation.

Father-daughter duo co-author research paper on new grapefruit cybrids

When Jude Grosser's daughter, Melinda, was in elementary school, he would often take her to his laboratory at the University of Florida's Citrus Research and Education Center, where he works as a researcher on citrus diseases and creating new varieties.
