The brains of all vertebrates display gender-related differences. In songbirds, for example, the size of the brain areas that control their singing behaviour could be linked to the size of their song repertoires. In many songbird species, only the males sing and indeed, they do have larger song control areas in the brain than females. However, even species where both sexes sing identically, display the same sex differences in their brain structure. Researchers at the Max Planck Institute for Ornithology in Seewiesen have now demonstrated for the first time in the white-browed ...

DARIEN, Ill. – According to new research that will be presented Saturday, June 11, at the 20th Anniversary Meeting of the American Academy of Dental Sleep Medicine (AADSM), children with enlarged tonsils and adenoids who wore an oral appliance for six months experienced more favorable craniofacial growth, enlargement of pharyngeal dimensions, and improved breathing and snoring during sleep. Enlarged tonsils and dental malocclusion have a strong relation with sleep disturbance in children. Its consequences can include abnormalities of craniofacial growth and facial morphology ...

DARIEN, Ill. – According to new research that will be presented Saturday, June 11, at the 20th Anniversary Meeting of the American Academy of Dental Sleep Medicine (AADSM), objective compliance measurements agree with subjective compliance estimates in patients with obstructive sleep apnea (OSA) undergoing oral appliance therapy (OAT) – a finding that is not apparent in patients using continuous positive airway pressure (CPAP) therapy. Results show that the objective mean wearing time in the whole group was 6.8 hours per night. Among 21 patients who filled out the subjective ...

DARIEN, Ill. – According to new research that will be presented Saturday, June 11, at the 20th Anniversary Meeting of the American Academy of Dental Sleep Medicine (AADSM), the apnea-hypopnea index (AHI) in patients with severe obstructive sleep apnea (OSA) was more improved by a combination treatment of a mandibular advancement splint (MAS) and positive airway pressure (PAP) therapy than by continuous positive airway pressure (CPAP) therapy alone. Results show that without lowering the pressure substantially, CPAP tolerance can be improved and severe OSA can be effectively ...

DARIEN, Ill. – New research that will be presented Saturday, June 11, at the 20th Anniversary Meeting of the American Academy of Dental Sleep Medicine (AADSM) in Minneapolis, Minn., quantified the efficacy of mandibular advancement splints (MAS) using a self-administered, at-home device to monitor snoring and sleep-disordered breathing. Clinical assessment of MAS efficacy in the treatment of snoring and obstructive sleep apnea (OSA) is based predominantly on subjective reports by the patient and partner, and less commonly, on the apnea hypopnea index (AHI), which is ...

The Aurora A kinase may contribute to polycystic kidney disease (PKD) by inactivating a key calcium channel in kidney cells, according to a study in the June 13 issue of The Journal of Cell Biology (www.jcb.org). Aurora A is an oncogene best known as a regulator of mitotic progression. But the kinase has important functions during interphase as well, when it can promote cilia disassembly and can be activated by elevated calcium levels. Because both calcium signaling and cilia are defective in PKD, researchers from the Fox Chase Cancer Center in Philadelphia wondered whether ...

PROVIDENCE, R.I. [Brown University] — A new Brown University computer analysis that predicts the effect of genetic mutations on how the body splices mRNA indicates as many as a third of disease-related mutations may be linked to splicing problems — more than double the proportion previously thought. "Something like 85 percent of the mutations in the Human Gene Mutation Database are presumed to affect how proteins are coded, but what this work shows is that 22 percent of those are affecting the splicing process," said William Fairbrother, assistant professor of biology ...

A paper published online on June 13 in the Journal of Experimental Medicine (www.jem.org) identifies new gene mutations in patients with chronic lymphocytic leukemia (CLL)—a disease often associated with lack of response to chemotherapy and poor overall survival. CLL is the most common leukemia in the Western world, but the disease varies greatly from patient to patient with regard to prognosis, survival, and disease course. In attempt to understand the genetic basis for this heterogeneity, a group led by Riccardo Dalla-Favera at Columbia University and Gianluca Gaidano ...

National Institutes of Health researchers have identified a new pathway that sets the clock for programmed aging in normal cells. The study provides insights about the interaction between a toxic protein called progerin and telomeres, which cap the ends of chromosomes like aglets, the plastic tips that bind the ends of shoelaces. The study by researchers from the National Human Genome Research Institute (NHGRI) appears in the June 13, 2011 early online edition of the Journal of Clinical Investigation. Telomeres wear away during cell division. When they degrade sufficiently, ...

A team of researchers, led by Emmanuel Nivet, now at the Salk Institute for Biological Studies, La Jolla, has generated data in mice that suggest that adult stem cells from immune system tissue in the smell-sensing region of the human nose (human olfactory ecto–mesenchymal stem cells [OE-MSCs]) could provide a source of cells to treat brain disorders in which nerve cells are lost or irreparably damaged. Stem cells are considered by many to be promising candidate sources of cells for the regeneration and repair of tissues damaged by various brain disorders (including traumatic ...

In one of the first studies of its kind, UCLA researchers used a unique brain scan to assess the levels of amyloid plaques and neurofibrillary tangles — the hallmarks of Alzheimer's disease — in adults with Down syndrome. Published in the June edition of the Archives of Neurology, the finding may offer an additional clinical tool to help diagnose dementia in adults with Down syndrome, a genetic disorder caused by the presence of a complete or partial extra copy of chromosome 21. Adults with this disorder develop Alzheimer's-like plaque and tangle deposits early, ...

Spring flowers are opening sooner and songbirds breeding earlier in the year, but scientists know little about how climate change is affecting phenology – the timing of key biological events – in UK mammals. Now, a new study on Northumberland's iconic Chillingham cattle published in the British Ecological Society's Journal of Animal Ecology shows climate change is altering when these animals breed, and fewer calves are surviving as a result. The team of ecologists lead by Dr Sarah Burthe of the Centre for Ecology & Hydrology were able to use the cattle to discover more ...
