Now a new phase of research can explore the development of drugs that will stem the development of dementias such as Alzheimer's
Globally there are at least 44.4 million dementia sufferers with the numbers expected to soar. The key breakthrough by Dr Olajide and his co-researchers is to demonstrate that punicalagin which is a polyphenol--a form of chemical compound--found in pomegranate fruit can inhibit inflammation in specialised brain cells known as micrologia.
and regular consumption of pomegranate has a lot of health benefits--including prevention of neuro-inflammation related to dementia he says recommending juice products that are 100 per cent pomegranate meaning that approximately 3. 4 per cent will be punicalagin the compound

Dr. Schnell and his team have developed a vaccine that activates the immune system to produce large amounts of antibodies against three virus strains
It includes the Zaire strain of Ebola virus that is currently spreading across West Africa as well as the Sudan strain and the Marburg virus a virus in the same family as Ebola
Together with SAB Dr. Schnell is applying for a grant that would allow the team to vaccinate the cows with his vaccine in order to produce large quantities of antibodies specific for the three viral strains.

and more resistant to environmental stress in West african environments than Asian varieties Wing said. African rice already has been crossed with Asian rice to produce new varieties under a group known as NERICA which stands for New Rice for Africa.
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.

#How gardens could help dementia carea new study has revealed that gardens in care homes could provide promising therapeutic benefits for patients suffering from dementia.
) the systematic review also found that gardens could offer welcome spaces for interactions with visitors helping to stimulate memories for dementia patients
Dementia is a global public health priority with reports suggesting that 7. 7 million new cases are identified each year.
Almost half of the elderly people living in residential care have dementia or dementia symptoms a figure
The study's lead researcher Rebecca Whear said There is an increasing interest in improving dementia symptoms without the use of drugs.
We think that gardens could be benefitting dementia sufferers by providing them with sensory stimulation and an environment that triggers memories.
if gardens are to be useful in the future care of dementia patients. These include understanding possible hazards that a garden might represent to residents
We want to pursue these answers to ensure that care experiences can be maximised for sufferers of dementia their carers and families.
However once domestication by humans began plants grown as crops had to cope with a new set of artificial selection pressures such as delivering a high yield and greater stress tolerance.'
whether commercial honey bee strains are actually more productive all things considered. There is not much point in having a highly productive strain

#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.
The analysis also showed that low-income Kansans with mental illness are more likely to be smokers (40.1 percent.
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 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
Their discovery should help biologists better understand how the steadily increasing levels of CO2 in our atmosphere (which last spring for the first time in recorded history remained above 400 parts per million) are affecting the ability of plants and economically important crops to deal with heat stress and drought.

This study validates the results of earlier research that has reported associations between having a child with autism
and may pose threats to brain development during gestation potentially resulting in developmental delay or autism.
and linking the data to the residential addresses of approximately 1000 participants in the Northern California-based Childhood Risk of Autism from Genetics and the Environment (CHARGE) Study.
The study includes families with children between 2 and 5 diagnosed with autism or developmental delay or with typical development.

Organophosphates applied over the course of pregnancy were associated with an elevated risk of autism spectrum disorder particularly for chlorpyrifos applications in the second trimester.
Pyrethroids were associated moderately with autism spectrum disorder immediately prior to conception and in the third trimester.
Research from the CHARGE Study has emphasized the importance of maternal nutrition during pregnancy particularly the use of prenatal vitamins to reduce the risk of having a child with autism.

The widespread use of antibiotics in livestock for preventive or curative purposes or as growth promoters directly contributes to the increasing prevalence of resistant strains of bacteria to antibiotics both at local and global levels.
since the completion of the first high-quality rice genome sequence in 2005 there has been limited change in breeding practices that are important for producing improved and better adapted rice strains.
which take advantage of the natural variation between different plant strains and information on the genetic mechanisms that underlie these traits to select strains for breeding that will be more successful in producing hybrid strains with characteristics that are suited highly for growing successfully in different environments.
Dr. Zhikang Li the Project Director at CAAS stated that the 3000 Rice Genomes Project is part of an ongoing effort to provide resources specifically for poverty-stricken farmers in Africa
not only 13.4 terabytes of data they have collected also seeds from each strain (available in the International Rice Genebank Collection housed at IRRI).
Having banked seeds is essential to make full use of these now genetically defined strains to develop
and sustain the most appropriate hybrid strains for different environments. There remains however one additional component to achieve this goal:
and breeders to directly link the genetic information (genotype) to the physical traits (phenotype) of these different strains.
since the development of agriculture typically use apparent physical traits to guide strain selection for crossbreeding with the hope that the offspring will manifest a combination and improvement of the desired traits such as drought pest and disease resistance
when two strains are bred. Thus trial and error and multiple successive breeding stages are required often. Having full knowledge of the genetic makeup of a plant allows researchers to identify genetic markers related to specific physical traits
This information allows a breeder to make more intelligent choices in strain selection resulting in more accurate and rapid development of rice strains that are suited better to different agricultural environments in poor and environmentally stressed economies.
As traditional methods of controlling crop disease become less effective the need to breed new strains of crops with an inbuilt resistance to the disease pathogens increases.
which will help us to be more successful in breeding new strains of crops for resistance.
help dairy producersconsumers may have more palatable low-fat products and milk producers a solution to an industry-wide problem through use of a unique strain of lactic acid bacteria according to Ashraf Hassan
After examining bacteria from the dairy environment for more than 15 years Hassan found a strain that mimics fat.
The strain Hassan discovered produces polysaccharides with high water binding capacity that then improve the quality of low-fat dairy products.
The polysaccharide produced by this strain also improves the functionality of proteins recovered from the cheese by product whey Hassan explained.
Furthermore the polysaccharide produced by this strain minimizes the negative impact of heat on milk protein during pasteurization according to Hassan.

The current study describes how crossbreeding the fat-1 mouse with another strain transgenic for the c. elegans gene fat-2
Called the Omega mouse this strain produces both omega-6 and omega-3 fatty acids in its tissue.
The crossbreeding protocol produces four different strains within the same litter--Omega mice that express both fat-1 and fat-2 strains that express only one of the c. elegans genes
Even when fed a high-carbohydrate fat-free diet both the Omega and fat-2 strains produced significant levels of both essential fatty acids.
Industrial manufacturers seek to diversify their products by adding selected strains to milk from which the native microflora have been removed.

Concerned hunters and foresters sent the carcasses to the University of Veterinary medicine Vienna for analysis. Extensive investigations have revealed now that the animals died of bacterial pneumonia caused by two strains of bacteria that are highly unusual in chamois.
However each stress resulted in very different expression patterns. Traditionally weeds have been thought to reduce crop growth and yield due to competition for water nutrients and light.
Next the researchers look at the effect of water stress on gene expression using corn planted on high and low ground.

It has favorable effects on body mass index waist circumference cholesterol inflammation and oxidative stress.
Climate change will add to both stress and costs. Rising temperatures lead to increased demand for water and energy and impacts on agricultural practices.
Now the changing climate is imposing additional stresses...Coastal lifelines such as water supply infrastructure and evacuation routes are increasingly vulnerable to higher sea levels
or so others will increasingly suffer from stresses due to extreme heat drought disease and heavy downpours.

After screening many hundreds of potential biocontrol strains of bacteria that were isolated from farms and natural environments in the Mid-atlantic region we found about 10 isolates of bacteria representing very different genera
The resistant strains multiply in the fly and can be left behind on food by fly regurgitation or spitting and defecation.
The resistant strains then survive and are selected by antibiotic treatments. Currently we have situations where people get infections they die from
We just know there are multiple venues where wildlife can acquire resistant strains and move them around in the environment.

According to the National institutes of health cirrhosis is the 12th leading cause of death by disease in the U s as with many other human pathologic conditions end-stage liver disease goes hand in hand with oxidative stress
Cells keep oxidative stress under control through various mechanisms said Donna Zhang a professor in the UA Department of Pharmacology
Under normal healthy conditions when no oxidative stress response is needed an enzyme called Keap1 constantly chews up Nrf2 keeping its level low.
Then under stress from reactive oxygen molecules or when you eat antioxidants from certain plants like broccoli sprouts it prevents Keap1 from eating up Nrf2 allowing it to accumulate in the cell explained Zhang who is also a member of the UA BIO5 Institute.
when subjected to high oxidative stress to limit the damage from the destructive oxygen compounds. During liver cirrhosis Nrf2 should be induced by oxidative stress
but for reasons unclear until this study this does not happen. This was a puzzle before we did our study she said.
When Zhang and her colleagues studied tissue samples from a human cirrhotic liver they discovered the reason behind the inexplicably low Nrf2 levels in the face of rampant oxidative stress.
As liver cirrhosis progresses excessive inflammation triggers the garbage-mediated stress response and Hrd1 becomes very abundant
