UCLA researchers identify chemical changes in brains of patients with early-onset Alzheimer's

With a lack of effective treatments for Alzheimer's, most of us would think long and hard about whether we wanted to know years in advance if we were genetically predisposed to develop the disease. For researchers, however, such knowledge is a window into Alzheimer's disease's evolution.

Infectious disease-fighting drugs could be designed to block pathogen's entry into cells

New research shows that infectious disease-fighting drugs could be designed to block a pathogen's entry into cells rather than to kill the bug itself.

Arthrex to market ThermoGenesis Res-Q 60 System technology for PRP and BMC preparation

ThermoGenesis Corp., a leading supplier of innovative products and services that process and store human cell concentrates, said today it has entered into a five year collaboration with Arthrex, Inc., under which Arthrex will market ThermoGenesis' Res-Q 60 (Res-Q) System technology for use in the preparation of autologous Platelet Rich Plasma (PRP) and Bone Marrow Concentrate (BMC).

Study finds no support for primary pathogenic role of LBs in PD

The pathology of Parkinson's disease is characterized by a loss of dopamine-producing neurons in the pars compacta of the substantia nigra (SN), an area of the brain associated with motor control, along with the development of α-synuclein (αS) protein in the form of Lewy bodies (LB) in the neurons that survive. The spread of LB pathology is thought to progress along with the clinical course of Parkinson's disease, although recent studies suggest that they are not the toxic cause of cell death.

Personalized medicine could offer a valuable tool to help combat the diabetic epidemic

With the trend in healthcare moving toward an era of personalized medicine, there is much anticipation and hope that customized approaches to prevention and treatment based on a person's genetic make-up will result in better health outcomes. Some advances, most notably with prevention and treatment of breast and colon cancer, have been widely heralded, raising questions about the potential for personalized medicine for other common diseases, such as diabetes.

Researchers use 3-D imaging to identify proteins involved in arterial stiffness

Human arteries - some smaller than a strand of hair - stiffen as a person ages. This stiffening is a factor in cardiovascular disease, the leading cause of death in the United States, because it contributes to the circulatory complications in disorders such as high blood pressure and diabetes. University of Missouri researchers have now used advanced 3-D microscopic imaging technology to identify and monitor the proteins involved in this stiffening process.

ORMOSIL nanoparticles show promise as potential drug delivery vehicle

In the images of fruit flies, clusters of neurons are all lit up, forming a brightly glowing network of highways within the brain. It's exactly what University at Buffalo researcher Shermali Gunawardena was hoping to see: It meant that ORMOSIL, a novel class of nanoparticles, had successfully penetrated the insects' brains. And even after long-term exposure, the cells and the flies themselves remained unharmed.

Scientists help explain how brain locates images that look like faces

Objects that resemble faces are everywhere. Whether it's New Hampshire's erstwhile granite "Old Man of the Mountain," or Jesus' face on a tortilla, our brains are adept at locating images that look like faces. However, the normal human brain is almost never fooled into thinking such objects actually are human faces.

MAL3-101 appears to have potent anti-tumor effects on multiple myeloma

A new study from SUNY Downstate Medical Center in Brooklyn, New York, shows that MAL3-101, a recently developed inhibitor of the heat shock protein 70 (Hsp70), appears to have potent anti-tumor effects on multiple myeloma, a bone marrow cancer.

Scientists can now observe enhancer activity in real embryo

As an embryo develops, different genes are turned on in different cells, to form muscles, neurons and other bodily parts. Inside each cell's nucleus, genetic sequences known as enhancers act like remote controls, switching genes on and off. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, can now see - and predict - exactly when each remote control is itself activated, in a real embryo.

QIAGEN's therascreen EGFR Mutation Detection Kit receives Japanese regulatory approval

QIAGEN today announced the regulatory approval of its therascreen EGFR Mutation Detection Kit RGQ in Japan. EGFR, the epidermal growth factor receptor, has been shown to play an important role in certain cancers and is the target of many new anticancer drugs.

Females can manipulate sex of their offspring

Females influence the gender of their offspring so they inherit either their mother's or grandfather's qualities. 'High-quality' females - those which produce more offspring - are more likely to have daughters. Weaker females, whose own fathers were stronger and more successful, produce more sons.

Urinary biomarkers can diagnose AKI in high-risk patients

Acute kidney injury (AKI) has severe consequences, with a 25 to 80 percent risk of in-hospital death. Researchers have found a way to diagnose AKI using a urine test, enabling emergency departments to identify these high-risk patients when they first arrive at the hospital.

Personalized therapies may improve survival and QoL of patients with glioblastoma

Personalized prognostic tools and gene-based therapies may improve the survival and quality of life of patients suffering from glioblastoma, an aggressive and deadly form of brain cancer, reports a new University of Illinois study funded by the NIH National Cancer Institute.

Modified probiotics could one day decrease risk of Listeria infection

Modified probiotics, the beneficial bacteria touted for their role in digestive health, could one day decrease the risk of Listeria infection in people with susceptible immune systems, according to Purdue University research.

DHA plays an essential role in creating healthy sperm

Who knew that male fertility depends on sperm-cell architecture? A University of Illinois study reports that a certain omega-3 fatty acid is necessary to construct the arch that turns a round, immature sperm cell into a pointy-headed super swimmer with an extra long tail.

Insulin induces formation of new elastin in cultures of human aortic smooth muscle cells

New research reveals that insulin applied in therapeutic doses selectively stimulates the formation of new elastic fibers in cultures of human aortic smooth muscle cells.

Life Technologies takes orders for new benchtop Ion Proton Sequencer

Life Technologies Corporation today announced it is taking orders for the new benchtop Ion Proton Sequencer that is designed to sequence the entire human genome in a day for $1,000.

Researchers uncover exact function of LARGE enzyme linked with MD

Researchers at the University of Iowa have worked out the exact function of an enzyme that is critical for normal muscle structure and is involved in several muscular dystrophies. The findings, which were published Jan. 6 in the journal Science,, could be used to develop rapid, large-scale testing of potential muscular dystrophy therapies.

Study identifies netrin-1 as novel target for atherosclerosis

A new study by NYU Langone Medical Center researchers identified a new culprit that leads to atherosclerosis, the accumulation of fat and cholesterol that hardens into plaque and narrows arteries. The research, published online by Nature Immunology on January 8, 2012, explains why cholesterol-laden, coronary artery disease-causing cells called macrophages, accumulate in artery plaques.
