Deep breathing and Stress


Mar 30, 2017

,,,,,
When people are anxious before getting surgery, doctors
and nurses often tell them to take slow, deep breaths with
long exhalations. It may seem 
like an inadequate way to quell
anxiety, but in many cases, it actually works.
Now scientists describe why deep breathing, including the
breath-focus of meditation, can induce such calm and
tranquility. In a paper published in Science, researchers
led by Mark Krasnow, a professor of biochemistry at Stanford
University, found that in mice, a group of nerves in the brain

that regulates breathing has a direct connection to the arousal
center of the brain. In other words, breathing can have a direct
effect on the overall activity level of the brain./.../

Tau protein

Tau protein—not amyloid—may be key driver of Alzheimer’s symptoms

One of the telltale signs of Alzheimers disease (AD) is sticky plaques of ß-amyloid protein, which form around neurons and are thought by a large number of scientists to bog down information processing and kill cells. For more than a decade, however, other researchers have fingered a second protein called tau, found inside brain cells, as a possible culprit. Now, a new imaging study of 10 people with mild AD suggests that tau deposits—not amyloid—are closely linked to symptoms such as memory loss and dementia. Although this evidence won’t itself resolve the amyloid-tau debate, the finding could spur more research into new, tau-targeting treatments and lead to better diagnostic tools, researchers say.;...;

Unsaturated fatty acids and AD

Alzheimer's linked to unsaturated fatty acids in the brain

Published: 
[illustration of brain regions]


While it is not yet clear what causes Alzheimer's disease, researchers are examining a variety of genetic, environmental, and lifestyle causes. New research examines some of the key brain regions involved in the development of Alzheimer's and finds several fatty acids to be associated with this form of dementia.

The Alzheimer's Association estimate that every 66 seconds, an adult in the United States develops Alzheimer's disease (AD). Alzheimer's-related mortality has increased by as much as 89 percent since the year 2000./.../

oxybutynin and dementia

Concern over high US prescribing levels of common drug linked to dementia

MNT homePublished: 
A new analysis raises concern over high prescription rates in the USA of a common
drug used to treat overactive bladder. The drug, oxybutynin, when taken orally, is
consistently linked with cognitive impairment and dementia in the elderly. The analysis
shows that oxybutynin, is prescribed in more than a quarter of cases of overactive
bladder (27.3%), even though other more suitable drugs are available. This work is
presented at the European Association of Urology conference in London, where
concerns are also being expressed about the lack of funded alternatives to oxybutynin
in Europe.
Overactive bladder (OAB) is extremely common in persons over 65. Initial treatment
is normally via behavioural modifications, which can then be followed by first-line
medical treatment such as antimuscarinic medications, including oxybutynin. Antimuscarinic
drugs are synthetic compounds, originally derived from mushrooms, which block the
activity of the muscarinic acetylcholine receptor. They have several uses, including
control of OAB. Oxybutynin is the least expensive antimuscarinic used for OAB, and
so tends to be the drug of choice for health care plans such as Medicare. However,
a body of evidence has shown that oxybutynin is linked to greater cognitive decline
in the elderly1./...

Rheumatoid Arthritis and oral care

To Prevent Rheumatoid Arthritis, Look Past the Joints to the Gums

JAMA. 2017;317(12):1201-1202. doi:10.1001/jama.2017.0764
The mouth may seem like a strange place to search for a culprit in a disease that primarily affects the joints. But a recent collaboration by a group of multidisciplinary researchers suggests that one type of oral bacteria may be an important trigger in about half of rheumatoid arthritis (RA) cases.
Image description not available.
The findings, published in Science Translational Medicine late last year, appear to confirm something that’s been suspected for at least a century: In some cases, gum-disease causing oral bacteria may set off a cascade of events that leads to the autoimmune form of arthritis./.../

Pulmões fabricando plaquetas



O Amigo Gruswzynski em enviou:
São Paulo – Cientistas da Universidade da Califórnia, em São Francisco, descobriram que os pulmões desempenham um papel que vai além da respiração. Em uma série de experimentos feita com ratos, os pesquisadores notaram que os órgãos do animal produziram mais da metade das plaquetas – componentes do sangue necessários para a coagulação – envolvidas na circulação sanguínea.

Segundo Mark Looney, autor principal do estudo, isso significa que os pulmões humanos podem realizar uma função totalmente inesperada: a produção de sangue. “Esse achado definitivamente sugere uma visão mais sofisticada dos pulmões – que eles não são apenas para a respiração, mas também um parceiro fundamental na formação de aspectos cruciais do sangue”, disse o cientista em um comunicado./.../
