Researchers discover how to fight iron disorders with a drug against hypertension

We all know that iron deficiencies are dangerous, but also too much iron is bad for our health. Our body stores excess iron in various tissues, where it can lead to organ failure and even death if not treated before irreversible damage has occurred.

Targeting bladder tumor cells in vivo and in the urine with a peptide identified by phage display

Efforts to create nanoparticles that deliver anticancer drugs or imaging agents to tumors while avoiding healthy cells are often stymied by a lack of known tumor targets, that is, molecules found on the surface of malignant cells but not healthy cells.

Nanotechnology and the public: Effectively communicating nanoscale science and engineering concepts

If you could paint a gallon's worth of paint one nanometer thick, how much area could you cover?

New, rapid-detection system for Salmonella

The food and drink we consume have to pass strict quality controls. Nevertheless, these measures are not always sufficient, given that sometimes certain foodstuffs can still give rise to food poisoning, most often caused by micro-organisms. The Salmonella bacterium is undoubtedly one of the best known of these.

Loss of a universal tRNA feature

Scientists at the Virginia Bioinformatics Institute (VBI) report in the Journal of Bacteriology that two alphaproteobacteria lack the universal extra guanylate nucleotide typically found in the transfer RNA molecule tRNAHis.

Research helps explain origin of self-reactive B cells

Doctors have long wondered why, in some people, the immune system turns against parts of the body it is designed to protect, leading to autoimmune disease.

New understanding of blood pressure gene could lead to new treatments

Research by scientists at UCL (University College London) has clearly demonstrated for the first time the structure and function of a gene crucial to the regulation of blood pressure. The discovery could be important in the search for new treatments for illnesses such as heart disease, the UK's biggest killer.

Bright quantum dots help basic cancer biology studies

Though there is little doubt that nanoscale devices are going to play a critical role in improving cancer detection and treatment over the next five to ten years, nanoparticles are already having a major impact on the way that cancer biologists study the processes that go awry within malignant and metastatic cells.

Potential new cancer fighting drug found by mistake

Researchers in the United States appear to have almost inadvertently stumbled across what could be a new cancer treatment.

Corn, oats, cherries and red wine's high melatonin content can help delay ageing

The Spanish Ageing Research Network (Red Nacional de Investigación del Envejecimiento), funded by Carlos III Health Institute and headed by professor Darío Acuna Castroviejo, from the University of Granada, is very near to achieving one of today's Science greatest goals: allowing humans to age in the best possible health conditions.

Probing proteins can lead to better understanding of anti-tumor agents

There are a number of naturally occurring chemicals that are used in phototherapy of skin diseases. Hypocrellin A (HA), which can be extracted from a parasitic fungus, has been taken orally as a folk medicine for several centuries in China.

Scientists tackle huntingtin protein

McMaster scientists are very close to defining small molecule drugs that should be able to redirect the huntingtin protein from accumulating in the wrong place within brain cells, which could potentially translate to a therapy for Huntington's Disease (HD).

Design of gold nanoparticles for magnetic resonance imaging

Molecular complexes containing the element gadolinium are proven agents for increasing the diagnostic utility of magnetic resonance imaging (MRI), but their use in detecting small tumors is limited by the relatively weak signal these agents produce.

SH2B1 protein plays a key role in controlling body weight, response to insulin and leptin

A single protein in brain cells may act as a linchpin in the body's weight-regulating system, playing a key role in the flurry of signals that govern fat storage, sugar use, energy balance and weight, University of Michigan Medical School researchers report.

Cellular mechanism linked to inflammation and cancer

A team led by biochemists at the University of California, San Diego has found what could be a long-elusive mechanism through which inflammation can promote cancer. The findings may provide a new approach for developing cancer therapies.

RNA used to turn on genes to alleviate disease

A new technique that employs RNA, a tiny chemical cousin of DNA, to turn on genes could lead to therapeutics for conditions in which nudging a gene awake would help alleviate disease, researchers at UT Southwestern Medical Center say.

Small molecule targets weak mRNA

A new strategy for fighting cancer aims to make its genes get lost in translation, according to a report in the January 26, 2007, issue of the journal Cell.

Disorderly protein brings order to cell division

The secret to the ability of a molecule critical for cell division to throw off the protein yoke that restrains its activity is the yoke itself a disorderly molecule that seems to have a mind of its own, say investigators at St. Jude Children's Research Hospital, Innsbruck Medical University and Max Planck Institute.

Possible reason for severe side-effects of Northwick Park clinical trial

A possible reason why the Northwick Park clinical trial of the drug TGN1412 caused multiple organ failure in human volunteers is revealed in research presented at a conference near Paris.
