Gold nanoparticles for detecting melamine in milk

University of Miami assistant professor in the College of Engineering, Na Li and her collaborators have developed a fast, economical and easy method to detect melamine in milk. Melamine is the compound found in contaminated pet food and in tainted dairy products from China in 2007 and 2008 respectively.

Ancient hunter-gatherers were lactose intolerant, says study

The hunter-gatherers who inhabited the southern coast of Scandinavia 4,000 years ago were lactose intolerant. This has been shown by a new study carried out by researchers at Uppsala University and Stockholm University.

Invalidation of gene patents: ACMG celebrates US District Court ruling

The American College of Medical Genetics (ACMG), one of the original plaintiffs in the anti-gene-patenting lawsuit filed in 2009, celebrated the US District Court ruling yesterday that genes are "unpatentable."

Gene linked to kidney cancer in children discovered

Cancer Research UK-funded scientists have identified two genes linked to Wilms' tumour - a type of childhood kidney cancer - according to research published in Clinical Cancer Research.

Study finds potential role of NGF in islet transplantation

Islet transplantation is a promising treatment for type 1 diabetes mellitus. The promotion of angiogenesis is an important endeavor to prevent islet graft failure. Endothelial precursor cells (EPCs), a heterogeneous group originating in the hematopoietic compartment of bone marrow, have an important role in the angiogenesis of adult tissues.

Scientists create genetic map to identify mechanism behind heart abnormalities

Though heart disease is a major cause of disability and death, very little is understood about its genetic underpinnings. Recently, an international team of investigators at the Institute of Molecular Biotechnology of the Austrian Academy of Sciences (IMBA), Sanford-Burnham Medical Research Institute (Sanford-Burnham) and other organizations shed new light on the subject.

Brain stem cells in subventricular zone characterized by transcription factor Protein Tlx

The "cradle" of new neurons in the adult brain is well known. It is what is called the subventricular zone, a tissue structure lining the lateral ventricles. This is where neural or brain stem cells reside, which are responsible for generating new neurons if needed. For many years now, the subventricular zone has been suspected to be the origin of specific malignant brain tumors called gliomas, the most deadly type of which is glioblastoma.

New clues into genomic complexity of Mimivirus

A study published online today in the journal Genome Research offers surprising new clues into the genomic complexity of the giant Mimivirus, the largest known virus in the world. Previous studies have shown that unlike most viruses, the Mimivirus has more genes than many bacteria and performs functions that normally occur only in cellular organisms.

Researchers identify link between genetic mutation and schizophrenia

In what may provide the most compelling evidence to date, researchers at Columbia University Medical Center have illuminated how a genetic variant may lead to schizophrenia by causing a disruption in communication between the hippocampus and prefrontal cortex regions of the brain, areas believed to be responsible for carrying out working memory.

Mouse study indicates rapamycin drug prevents Alzheimer's disease, extends lifespan

If research results continue to be repeated and are turned into clinical trials, a drug already approved for some uses could be marshaled - sooner than we expect - to prevent Alzheimer's disease in humans and improve health to the end of life.

Genetic risk factor for schizophrenia can disrupt connectivity at level of single neurons

The strongest known recurrent genetic cause of schizophrenia impairs communications between the brain's decision-making and memory hubs, resulting in working memory deficits, according to a study in mice.

Mtb fine-tunes behaviour to escape detection and causes TB

Mycobacterium tuberculosis (Mtb) possesses extraordinary survival ability by masking itself from the host immune system and persisting for decades inside the host. Speaking at the Society for General Microbiology's spring meeting in Edinburgh today, Dr Kristine Arnvig provides further insight into how the bacterium causes tuberculosis (TB) by fine-tuning its behaviour in response to its surroundings to escape detection.

Scientists use non-viral, synthetic nanoparticle carrier to restores vision

Take a look at this: Scientists from Buffalo, Cleveland, and Oklahoma City made a huge step toward making the blind see, and they did it by using a form of gene therapy that does not involve the use of modified viruses.

Insight into how mutations in LRRK2 gene may cause familial Parkinson's disease

Using new one-of-a-kind "mouse models" that promise to have a significant impact on future Parkinson's disease research, Mount Sinai School of Medicine researchers are among the first to discover how mutations in a gene called LRRK2 may cause inherited (or "familial") Parkinson's disease, the most common form of the disease. The study, published in The Journal of Neuroscience, is the first in vivo evidence that LRRK2 regulates dopamine transmission and controls motor performance, and that the mutation of LRRK2 eliminates the normal function of LRRK2, leading to Parkinson's disease.

Combating immune suppressive cells in liver may prevent the spread of cancer: Study

Scientists have uncovered what could be a very important clue in answering one of the most perplexing questions about cancer: why does it spread to the liver more than any other organ? In a new research report published in the April 2010 issue of Journal of Leukocyte Biology, scientists from New York University describe experimental results suggesting that the immune system may be the reason.

Metabolon awarded U.S. patents for metabolomics methods

Metabolon, Inc., the leader in global metabolism through biomarker discovery and analysis, announced today the grant of US Patent 7,682,783 and US Patent 7,682,784 entitled "Methods for Drug Discovery, Disease Treatment and Diagnosis Using Metabolomics". The USPTO awarded the patents to Metabolon on March 23, 2010. The issued claims in the new patents are for uses of metabolomics to identify diagnostic biomarkers for depression and schizophrenia by profiling classes of metabolites in a sample.

Researchers develop experimental protocol to detect age-related memory disorders

By studying the aging of memory in the mouse, researchers in the Laboratoire Neurobiologie des Processus Adaptatifs have developed an experimental protocol that can detect age-related memory deficits at an early stage. They have shown that even at 10 months, which corresponds to a third of their life expectancy, some mice present with age-related memory disorders.
