New polymer nanoparticles can generate heat and kill colorectal cancer cells

Researchers at Wake Forest Baptist Medical Center have modified electrically-conductive polymers, commonly used in solar energy applications, to develop revolutionary polymer nanoparticles (PNs) for a medical application. When the nanoparticles are exposed to infrared light, they generate heat that can be used to kill colorectal cancer cells.

BRIGHTs bind to biomarkers of disease and light up to reveal their location

Called BRIGHTs, the tiny probes described in the online issue of Advanced Materials on Nov. 15, bind to biomarkers of disease and, when swept by an infrared laser, light up to reveal their location.

Sweat glands play a key role in providing cells for skin wound recovery

Turns out the same glands that make you sweat are responsible for another job vital to your health: they help heal wounds. Human skin is rich with millions of eccrine sweat glands that help your body cool down after a trip to the gym or on a warm day. These same glands, new University of Michigan Health System research shows, also happen to play a key role in providing cells for recovering skin wounds - such as scrapes, burns and ulcers.

Scientists uncover new role for TLR4 in development of tissue fibrosis or scarring

An international multi-disciplinary research team led by Northwestern Medicine scientists has uncovered a new role for the protein toll-like receptor 4 (TLR4) in the development of tissue fibrosis, or scarring.

Meningiomas likely results from hemodynamic changes associated with pregnancy

Meningiomas are a common type of benign brain tumor that sometimes grows dramatically in pregnant women. A new study suggests that this sudden tumor growth likely results from "hemodynamic changes" associated with pregnancy, reports the November issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Acetylon's ective histone deacetylase inhibitors to be showcased at 54th ASH annual meeting

Acetylon Pharmaceuticals Inc., a leader in targeted epigenetic drug discovery and development for enhanced therapeutic outcomes, today announced that its selective histone deacetylase (HDAC) inhibitors will be featured in five posters and one oral presentation at the 54th Annual Meeting of the American Society of Hematology (ASH), taking place December 8-11, 2012, in Atlanta, Georgia.

Musical tones can reset the brain and effectively reduce insomnia

If you are among the 50 percent of Americans who suffer from insomnia, then you have probably tried everything – from warm milk to melatonin pills or prescription medications to induce sleep – with varying degrees of success and side effects. But what if sleep could be achieved not by a substance, but through 'balancing' brain activity?

MRI reveals changes in brains of people with post-concussion syndrome

MRI shows changes in the brains of people with post-concussion syndrome (PCS), according to a new study published online in the journal Radiology. Researchers hope the results point the way to improved detection and treatment for the disorder.

Certain mutated cells continue DNA replication process even after drug treatment

Certain mutated cells keep trying to replicate their DNA - with disastrous results - even after medications rob them of the raw materials to do so, according to new research from USC.

Novel test reveals rate of progression of amyotrophic lateral sclerosis in patients

A novel test that measures proteins from nerve damage that are deposited in blood and spinal fluid reveals the rate of progression of amyotrophic lateral sclerosis (ALS) in patients, according to researchers from Mayo Clinic's campus in Florida, Emory University and the University of Florida.

Study: 2-PMPA improves cognition in mice with MS

Johns Hopkins researchers report the successful use of a form of MRI to identify what appears to be a key biochemical marker for cognitive impairment in the brains of people with multiple sclerosis (MS). In follow-up experiments on mice with a rodent form of MS, researchers were able to use an experimental compound to manipulate that same marker and dramatically improve learning and memory.

Novel technology can lead to more efficient and cheaper therapy for Pompe disease

VIB researchers from UGent and Vrije Universiteit Brussel , together with a team of the firm Oxyrane have developed a new technology that can lead to a more efficient and possibly also cheaper therapy for diseases such as Pompe disease. Oxyrane will now start developing a clinical program for this therapy in Pompe disease.

New insights into what causes uncontrollable bleeding in hemophilia patients

New insights into what causes uncontrollable bleeding in hemophilia patients are provided in a study published by Cell Press on November 20th in the Biophysical Journal. By revealing that blood clots spread in traveling waves through vessels, the study offers new strategies that could lead to the development of more effective treatments for hemophilia as well as common cardiovascular disorders.

Hsp104 protein switches mechanism to break up amyloid versus disordered clumps

Several fatal brain disorders, including Parkinson's disease, are connected by the misfolding of specific proteins into disordered clumps and stable, insoluble fibrils called amyloid. Amyloid fibrils are hard to break up due to their stable, ordered structure. For example, α-synuclein forms amyloid fibrils that accumulate in Lewy Bodies in Parkinson's disease. By contrast, protein clumps that accumulate in response to environmental stress, such as heat shock, possess a less stable, disordered architecture.
