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.

Maternal cigarette smoking reduces reading accuracy in children

Yale School of Medicine researchers have found that children born to mothers who smoked more than one pack per day during pregnancy struggled on tests designed to measure how accurately a child reads aloud and comprehends what they read.

Aradigm’s Lipoquin provides full protection in murine models of pneumonic plague

Scientists from the UK Defence Science and Technology Laboratory (Dstl) report, in a preliminary study, that they have demonstrated that a single dose of Aradigm Corporation's liposomal ciprofloxacin formulation Lipoquin administered 24 hours after exposure to a lethal dose of the bacterium Yersinia pestis provided full protection in a murine model of pneumonic plague.

Scientists identify two genetic risk factors for sagittal craniosynostosis

Seattle Children's Research Institute, together with an international team of scientists and clinicians from 22 other institutions, have identified two genetic risk factors for the most common form of non-syndromic craniosynostosis, a birth defect in which the bony plates of an infant's skull prematurely fuse. The condition is known as sagittal craniosynostosis and often results in an abnormal head shape and facial features.

IL-13 receptor system could play a major role in Parkinson's

Deciphering what causes the brain cell degeneration of Parkinson's disease has remained a perplexing challenge for scientists. But a team led by scientists from The Scripps Research Institute (TSRI) has pinpointed a key factor controlling damage to brain cells in a mouse model of Parkinson's disease.

Researchers discover new cause of hydrocephalus

Researchers at the University of Iowa have discovered a new cause of hydrocephalus, a devastating neurological disorder that affects between one and three of every 1,000 babies born. Working in mice, the researchers identified a cell signaling defect, which disrupts immature brain cells involved in normal brain development.

Researchers discover new gene for susceptibility to Alzheimer's disease

A large-scale international study involving French researchers from the Inserm-Institut Pasteur Lille-Universit- Lille Nord de France "Public health and molecular epidemiology of ageing-related diseases" joint research unit led by Philippe Amouyel, has just discovered a gene for susceptibility to a rare disease that causes susceptibility to a common one, Alzheimer's disease, providing evidence of the heterogeneous aetiology of Alzheimer's disease.

CFFT announces major expansion of research collaboration with Pfizer

Cystic Fibrosis Foundation Therapeutics Inc. (CFFT), the nonprofit drug discovery and development affiliate of the Cystic Fibrosis Foundation, today announced a major expansion of its research collaboration with Pfizer Inc. designed to discover new drugs to treat people with the most common mutation of CF, Delta F508.

New fiber-optic device can deliver light to the brain in 3D

A new tool for neuroscientists delivers a thousand pinpricks of light to a chunk of gray matter smaller than a sugar cube. The new fiber-optic device, created by biologists and engineers at the Massachusetts Institute of Technology (MIT) in Cambridge, is the first tool that can deliver precise points of light to a 3-D section of living brain tissue. The work is a step forward for a relatively new but promising technique that uses gene therapy to turn individual brain cells on and off with light.

Overexpression of BCL6 results in transformation of neural stem cells into cortical neurons

The cerebral cortex is the most complex structure in our brain and the seat of consciousness, emotion, motor control and language. In order to fulfill these functions, it is composed of a diverse array of nerve cells, called cortical neurons, which are affected by many neurological and neuropsychiatric diseases.

Four New York students named National Finalists in Siemens Competition

Months of dedication and hard work in science, technology, engineering and mathematics (STEM) paid off tonight for four students named National Finalists in the Siemens Competition in Math, Science & Technology, the nation's premier research competition.

ReFIT algorithm improves speed and accuracy of neural prosthetics

When a paralyzed person imagines moving a limb, cells in the part of the brain that controls movement still activate as if trying to make the immobile limb work again. Despite neurological injury or disease that has severed the pathway between brain and muscle, the region where the signals originate remains intact and functional.

New nanoparticle halts relapsing remitting multiple sclerosis in mouse model

In a breakthrough for nanotechnology and multiple sclerosis, a biodegradable nanoparticle turns out to be the perfect vehicle to stealthily deliver an antigen that tricks the immune system into stopping its attack on myelin and halt a model of relapsing remitting multiple sclerosis (MS) in mice, according to new Northwestern Medicine research.
