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.
The study of nearly 6000 people in five provinces in China reveals that people exposed to passive smoking have increased a significantly risk of severe dementia syndromes.

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
and reduce the dementia epidemic worldwide.''He added:''The increased risk of severe dementia syndromes in those exposed to passive smoking is increased similar to risk of coronary heart disease--suggesting that urgent preventive measures should be taken not just in China but many other countries.'

Low mental wellbeing is linked strongly to mental illness and mental health problems but high mental wellbeing is more than the absence of symptoms or illness;
it is a state in which people feel good and function well. Optimism happiness self-esteem resilience and good relationships with others are all part of this state.
Mental wellbeing is important not just to protect people from mental illness but because it protects people against common and serious physical diseases.

Before this study we didn't know much about the persistence of livestock-associated strains among workers in the United states whose primary full-time jobs involve working inside large industrial hog-confinement facilities says study author Christopher D
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.
whether the strains were traditionally found in livestock or humans and whether the bacteria were drug resistant.
while 16 of them (73 percent) carried the livestock-associated strain at some point. In contrast only about one-third of the general population carry a strain of Staphylococcus aureus associated with humans.
But 10 of the 22 workers (46 percent) were what the researchers call persistent carriers of livestock-associated Staph meaning they had these strains in their noses all

because many of the genes code for traits that make African rice resistant to environmental stress such as long periods of drought high salinity in the soils and flooding.
After decades of promoting high-yielding Asian varieties the emphasis now is on developing types that combine the former's higher yields with glaberrima's tolerance of environmental stress Carney noted.

#Adults with mental illness twice as likely to use tobaccokansas adults with mental illness are twice as likely to use tobacco as adults without mental illness according to a new report by RTI International and funded by the Kansas Health Foundation.
The report found 37.8 percent of Kansas adults with mental illness smoke compared to 17.3 percent of adults without mental illness.
Nearly one-half of Kansas adults who experience mental illness reported smoking in the last 30 days.
Smoking rates are highest among those with serious mental illness multiple disorders and substance use disorders.
The smoking rate among adults with mental illness remains high despite progress made in tobacco control
As a result people with mental illness are increased at an risk of negative health financial and social outcomes associated with their tobacco use.
and health behaviors and include questions about tobacco use and mental health. The analysis also showed that low-income Kansans with mental illness are more likely to be smokers (40.1 percent.
Individuals below the poverty level make up 9. 8 percent of the adult population in the state
but account for 24 percent of the adult population with mental illness. While smoking rates are highest among Kansans with mental illness the report found that adults with mental illness are more likely to have tried to quit smoking than those without mental illness.
The research showed 64.7 percent of Kansas smokers with mental illness made an attempt to quit compared to 55.3 percent of those without mental illness.
Additional findings include: -In 2012 10.2 percent of Kansas adults reported experiencing mental illness and 3. 4 percent of adults reported experiencing serious mental illness.
-Mental illness is associated significantly with poor physical health including health problems exacerbated by smoking. -Youth who reported mental illness were more than twice as likely to be current smokers (26.8 percent) as youth without mental illness (10.9 percent.
Our findings emphasize the importance of collaboration between the mental health and tobacco control communities to provide cessation support to individuals with mental illness who use tobacco Brown said.
To address the issue of tobacco use among those with mental illness and the challenges associated with making progress toward a solution the Kansas Health Foundation has launched a new effort to address tobacco use among Kansans with serious mental illness through its Fellows leadership program.
Through the years we've seen significant decreases in the percentage of Americans who smoke
but we've done very little to make strides in decreasing those rates among people with mental illness said Dr. Jeff Willett vice president for programs at the Kansas Health Foundation.
People with mental illness smoke at nearly double the rate of the general population. We see this collaborative effort being a call to action to both the mental health
and tobacco control communities. The report can be found online at: http://kansashealth. org/sites/default/files/T%26mi--Final 2. pdfstory Source:

#Fungus in yogurt outbreak poses threat to consumersthe fungus responsible for an outbreak of contaminated Greek yogurt last year is not harmless after all
but a strain with the ability to cause disease according to research published in mbioâ the online open-access journal of the American Society for Microbiology.
In September 2013 customers of Chobani brand Greek yogurt complained of gastrointestinal (GI) problems after consuming products manufactured in the company's Idaho plant.
The company issued a recall and it was believed at the time that the fungal contaminant Murcor circinelloides was only a potential danger to immunocompromised individuals.
In the study the researchers isolated a strain of the fungus from a yogurt container that was subject to recall.
Using a technique known as multi-locus sequence typing (MLST) they identified the strain as Mucor circinelloides f. circinelloides (Mcc.
Unlike other strains of the fungus that particular subspecies is associated commonly with human infections. Whole-genome sequence analysis of the yogurt isolate confirmed it as being closely related to Mcc
and also revealed the possibility that this fungus could produce harmful metabolites that were previously unknown in this species. The researchers then tested the strain on mice where the fungus showed an ability to cause lethal infections
