Sleep Apnea May Cause Heart Disease in Kidney Transplant Patients

Sleep apnea is common in individuals who receive a kidney transplant and is associated with increased risk of high blood pressure, heart disease or stroke, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN).

Researchers found that kidney transplant patients are just as likely to have this sleep disorder as dialyzed kidney disease patients who are on the transplant waiting list. Therefore, both types of patients who have sleep apnea should be considered at high risk for developing serious heart-related complications.

Cardiovascular disease is the most common cause of death in individuals who receive kidney transplants, and doctors monitor transplant recipients for high blood pressure, or hypertension, and other signs of heart trouble. Obstructive sleep apnea occurs when an individual stops breathing momentarily during sleep due to obstruction of the airway and has been linked to hypertension. Miklos Zsolt Molnar, MD, PhD (Semmelweis University, Budapest, Hungary), and his colleagues studied the prevalence of sleep apnea in kidney transplant patients and the effects the condition had on their cardiovascular risk.

The Flu Epidemic: All Fatal Ukraine Cases at GISAID Have RBD D225G Mutation

The patient data associated with the 10 Ukraine isolates sequenced by Mill Hill and deposited at GISAID has been updated with demographic information, suggesting that the samples were from 10 individuals and four of the samples were from deceased patients. These are the same four samples that have D225G (see list below). This association suggests that swine H1N1 with D225G is more aggressive and is cause for concern.

As noted earlier, D225G has been appended onto multiple genetic backgrounds via recombination, and the data from Ukraine adds further support. Samples from Ternopil and Khmelnitsky (see updated map) have a regional marker that is found in swine but no other human isolates. This marker is on all 6 Termopil isolates, indicating it was an early acquisition, but only the two fatal cases have D225G indicating it was appended onto the Ternopil genetic background. However, it is also found in the two fatal cases from Lviv, which do not have the regional marker. Similarly, earlier isolates with D225G represent distinct genetic backgrounds with D225G.

Norwegian scientists report mutated form of swine flu

Scientists in Norway announced Friday they had detected a mutated form of the swine flu virus in two patients who died of the flu and a third who was severely ill.

In a statement, the Norwegian Institute of Public Health said the mutation "could possibly make the virus more prone to infect deeper in the airways and thus cause more severe disease," such as pneumonia.

The institute said there was no indication that the mutation would hinder the ability of the vaccine to protect people from becoming infected or impair the effectiveness of antiviral drugs in treating people who became infected.

Oxford University scientists are using brain-scanning technology to understand how we learn to recognize and 'read' faces as children.

The research will also investigate whether there are any differences in the way people with autism spectrum disorders respond to seeing faces.

'Faces are really very similar in their basic features, but we are very good at recognizing different faces instantly. The brain has to be very specialized to be able to do this quickly and accurately,' says Dr Jennifer Swettenham, who is leading the study.

The ability to recognize faces is very important for communication and socializing. We need to be able to recognize people's facial features, and also understand their emotions, respond to where they are looking, and many other signs and indications.

If you have read any of my articles at OpEdNews over the past two years, or any by the many physicians who have also written articles and letters to the FDA commissioner, you will recognize what a bunch of stupid gobbledegook appears below. These critics of aspartame include Neurosurgeon Russell Blaylock, Internist H.J. Roberts, Psychiatrist Ralph Walton, and Pediatrician Kenneth Stoller, all medical doctors.

This new press release is one of the dumbest things I have ever read, but no surprise: aspartame is at the heart of the many reasons that Americans have gotten dumber, after decades of the "dumbing down" processes....

Mathematical Abilities Examined in Children with Fetal Alcohol Spectrum Disorder

Children with fetal alcohol spectrum disorder (FASD) have a number of cognitive deficits, but mathematical ability seems particularly damaged. Little is known about the brain structures related to mathematical deficits in children with FASD. A new study that used diffusion tensor imaging (DTI) to investigate the relationship between mathematical skills and brain white matter structure in children with FASD supports the importance of the left parietal area for mathematical tasks.

Results will be published in the February 2010 issue of Alcoholism: Clinical & Experimental Research.

"Children with FASD have learning difficulties with reading, memory, executive functioning, attention, and mathematics," said Christian Beaulieu, associate professor in the department of biomedical engineering at the University of Alberta and senior author for the study.

"Specific deficits in mathematics exist even when their global deficits are taken into account," added Claire D. Coles, professor of psychiatry and behavioral sciences at the Emory University School of Medicine. "Children with FASD are similar in their presentation to children with nonverbal learning disabilities, which are sometimes associated with visual/spatial deficits and math deficits; one of the factors thought to produce these effects is deficits in white matter integrity."

Sounds Can Penetrate Deep Sleep and Enhance Associated Memories Upon Waking

They were in a deep sleep, yet sounds, such as a teakettle whistle and a cat's meow, somehow penetrated their slumber.

The 25 sounds presented during the nap were reminders of earlier spatial learning, though the Northwestern University research participants were unaware of the sounds as they slept.

Yet, upon waking, memory tests showed that spatial memories had changed. The participants were more accurate in dragging an object to the correct location on a computer screen for the 25 images whose corresponding sounds were presented during sleep (such as a muffled explosion for a photo of dynamite) than for another 25 matched objects.

"The research strongly suggests that we don't shut down our minds during deep sleep," said John Rudoy, lead author of the study and a neuroscience Ph.D. student at Northwestern. "Rather this is an important time for consolidating memories."

New Cause of Osteoporosis: Mutation in a miroRNA

Many biological processes are controlled by small molecules known as microRNAs, which work by suppressing the expression of specific sets of genes. Xiang-Hang Luo and colleagues, at Second Xiangya Hospital of Central South University, People's Republic of China, have now identified a previously unknown microRNA (miR-2861) as crucial to bone maintenance in mice and humans.

Of clinical importance, expression of functional miR-2861 was absent in two related adolescents with primary osteoporosis.

Several lines of evidence determined the key role of miR-2861 in maintaining bone. First, miR-2861 promoted the in vitro development of a mouse stromal cell line into the cells responsible for bone formation. Second, in mice, in vivo silencing of miR-2861 inhibited bone formation and decreased bone mass. Last, analysis of ten patients with primary osteoporosis revealed two related adolescents in whom disease was caused by a mutation in the miR-2861 precursor (pre-miR-2861) that blocked expression of miR-2861.

These data led the authors to conclude that miR-2861 has an important role in controlling the generation of the cells responsible for bone formation and that defects in the processing of its precursor can cause osteoporosis.

Ancestry Attracts, but Love Is Blind

People preferentially marry those with similar ancestry, but their decisions are not necessarily based on hair, eye or skin colour. Research, published in BioMed Central's open access journal Genome Biology, shows that Mexicans mate according to proportions of Native American to European ancestry, while Puerto Ricans are more likely to settle down with someone carrying a similar mix of African and European genes.

Neil Risch, from the University of California, San Francisco, worked with a team of researchers to study the effects of ancestry on partner choice in Mexicans and Puerto Ricans living in their own countries or in the USA. The subjects came from The Genetics of Asthma in Latino Americans (GALA) study, conducted by Risch's UCSF colleague, Esteban Gonzalez Burchard. Risch said, "Latin America provides a unique opportunity to study population structure and non-random mating, due to the historical confluence of European, Native American and African racial groups over the past five centuries. We found that assortative mating, that is partner choice based on a shared ancestry, is very common in these populations."

Quite how our DNA influences our desires remains mysterious. Risch and his colleagues did not find that geography or socio-economic status could explain the ancestral influence on romance, and factors like hair, eye and skin colour individually only had a minor role. According to Burchard, "Certainly physical characteristics, such as skin pigment, hair texture, eye color, and other physical features are correlated with ancestry and are likely to be factors in mate selection. However, the spouse correlation for these traits and the correlation of these traits with ancestry were actually below what would be required to fully explain the phenomenon."

Aspirin Kills 400% More People than H1N1 Swine Flu

The CDC now reports that nearly 4,000 Americans have been killed by H1N1 swine flu. This number is supposed to sound big and scary, motivating millions of people to go out and pay good money to be injected with untested, unproven H1N1 vaccines. But let's put the number in perspective: Did you know that more than four times as many people are killed each year by common NSAID painkillers like aspirin?

The July 1998 issue of The American Journal of Medicine explains it as follows:
"Conservative calculations estimate that approximately 107,000 patients are hospitalized annually for nonsteroidal anti-inflammatory drug (NSAID)-related gastrointestinal (GI) complications and at least 16,500 NSAID-related deaths occur each year among arthritis patients alone." (Singh Gurkirpal, MD, "Recent Considerations in Nonsteroidal Anti-Inflammatory Drug Gastropathy", The American Journal of Medicine, July 27, 1998, p. 31S)
So for every person the CDC claims was killed by H1N1 swine flu this year, common painkillers like aspirin have killed four! Yet you don't see the CDC, FDA, WHO or mainstream media running around screaming about the extreme dangers of aspirin, do you? All those deaths apparently don't matter. Only swine flu deaths lead to hysteria.
