#Adults with mental illness or substance use disorder more likely to smokeadults aged 18 or older who experienced any mental illness
or who have had a substance use disorder in the past year are more likely to smoke and to smoke more heavily than others according to a new report by the Substance abuse and Mental health Services Administration (SAMHSA).
According to the report adults experiencing any mental illness or a substance use disorder in the past year represent 24.8 percent of the adult population
In terms of rates of cigarette smoking 38.3 percent of adults experiencing mental illness or substance use disorders were current smokers as opposed to 19.7 percent of those adults without these conditions.
That means that the rate of current cigarette smoking among adults experiencing mental illness or substance use disorders is 94 percent higher than among adults without these disorders.
although people with substance use disorders and no mental disorder constitute only 4. 9 percent of adults over age 18 they smoked 8. 7 percent of all cigarettes.
Similarly although those who had experienced both mental illness and a substance use disorder represented only 3. 8 percent of the population in the past year they smoked 9. 5 percent of all cigarettes.
The report defines any mental illness as any diagnosable mental behavioral or emotional disorder other than a substance use disorder.
It shows that people dealing with mental illness or substance abuse issues smoke more and are less likely to quit.
The report Adults with Mental illness or Substance Use Disorder Account for 40 Percent of All Cigarettes Smoked is based on the findings of SAMHSA's 2009-2011 National Survey on Drug Use and Health (NSDUH.

Moake whose research group was the first to describe how high shear stress could cause platelets to stick to VWF said I had thought that the condition might last for such a short time that it would be unmeasurable.
However previous research had shown that a type of physical stress called shear --which can arise in partially occluded arterial blood vessels with high flow rates--could cause PVWF to become sticky to platelets.
Moake's and Dong's groups prepared samples of PVWF subjecting some to the shear stresses known to induce clot formation.
which portion of PVWF changed its conformation during shear stress. They also determined how long the protein remained partially unfurled before relaxing into its natural shape.

#How plant communities endure stressthe Stress Gradient Hypothesis holds that as stress increases in an ecosystem mutually supportive interactions become more significant and negative interactions such as competition become less so.
and according to the Stress Gradient Hypothesis their positive interactions become measurably more influential when ecosystems become threatened by conditions such as drought.
of stress on six continents. Examining the data from each paper and contacting original authors when necessary He determined the overall trends across the many experiments.
Our results show that plant interactions generally change with increased environmental stress and always in the direction of an outright shift to facilitation (typical for survival responses) or a reduction in competition (typical from growth responses) the authors wrote in the paper published online.
We never observed an increase in competition at higher stress. These findings were consistent across fitness measures stress types growth forms life histories origins climatic zones ecosystems and methodologies.
or neutral effects at high stress whereas less competitive species e g. trees have strong facilitative effects at high stress the authors wrote.
Overall the researchers found studies with observations of greater degrees of stress increase--longer stress gradients--also observed greater degrees of shift toward positive interactions.
They could only persist in groups suggesting that with stress organisms were better off together--despite their competition--than apart.
Bertness published the Stress Gradient Hypothesis in Trends in Ecological Evolution with Ray Callaway then a graduate student at the University of California-Santa barbara. Callaway is now a professor at the University of Montana.
Hundreds of studies over two decades from sites around the world suggest that the Stress Gradient Hypothesis can be employed as a rule of thumb.

and leading to increased'stress'levels as detected through hormone analysis. The research published January 22 in the International Journal of Primatology took place in the tropical rainforests of the Mexican state of Veracruz
It shows that increases in howler monkey'travel time'--the amount of time needed to find requisite nourishment--are leading to increases in levels of stress hormones called glucocorticoids.
This leads to the increased'travel time'and consequent high levels of stress we are seeing in these primates as their habitats disintegrate.
As trying to catch the howlers to examine them would in itself be highly stressful for the animal the best way of evaluating stress levels in wild primates is by analysing their faeces for glucocorticoid stress hormones which are general to all vertebrates.
Through statistical modelling the researchers were able to determine that it is the'travel time'--rather than the increased foliage intake--causing high levels of stress.
Monkeys in disturbed habitats suffering high levels of stress is in itself unsurprising perhaps but now we think we know why the root cause from the primates perspective.
The authors say that further studies are required to fully understand the significance of increases in stress in howler monkeys living in disturbed habitats.
Determining the full relevance of our results for the conservation of primates living in forest fragments will require long-term studies of stress hormones

#Passive smoking increases risk of severe dementia, according to study in Chinaan international study by scientists in China the UK and USA has found a link between passive smoking and syndromes of dementia.

whether ETS increases the risk of dementia mainly due to lack of research. Previous studies have shown an association between ETS

They found that 10 percent of the group had severe dementia syndromes. This was significantly related to exposure level and duration of passive smoking.
The data from the Anhui cohort which were collected at baseline in 2001-03 for dementia syndromes
and in the follow up in 2007-08 for ETS exposure and dementia further excluded the possibility that dementia syndromes caused people to be exposed more to environmental tobacco smoke.
'Passive smoking should be considered an important risk factor for severe dementia syndromes as this study in China shows.
Avoiding exposure to ETS may reduce the risk of severe dementia syndromes.''China along with many other countries now has a significantly aging population
so dementia has a significant impact not only on the patients but on their families and carers.
& Dementia on the links between passive smoking and Alzheimer's disease strengthen the case for public health measures to protect people from exposure to environmental tobacco smoke.'
More campaigns against tobacco exposure in the general population will help decrease the risk of severe dementia syndromes

In Europe the children of livestock workers have been treated for infections caused by a new livestock-associated strain of MRSA (methicillin-resistant Staphylococcus aureus) that doesn't match the more widely found community-or hospital-associated strains.
This suggests the children may have been exposed to MRSA strains through their family members who worked on livestock farms.
Evidence of persistent carriage of this new livestock-associated strain and its drug resistance has led to restrictions on the non-therapeutic use of antibiotics in livestock overseas.
