#Why you need olive oil on your salada diet that combines unsaturated fats with nitrite-rich vegetables such as olive oil
The Mediterranean diet typically includes unsaturated fats found in olive oil nuts and avocados along with vegetables like spinach celery and carrots that are rich in nitrites and nitrates.
Thus the study concludes that the protective effect of the Mediterranean diet combining unsaturated fats
fatty acids within its tissues on a diet of carbohydrates or saturated fats. Called essential because they are necessary to maintain important bodily functions omega fatty acids cannot naturally be synthesized by mammals
Introducing into mammals the capacity to convert nonessential nutrients into essential fats could lead to new sustainable
and cost-effective resources of beneficial omega-3 fatty acids says Jing X. Kang MD Phd of the Laboratory for Lipid Medicine and Technology in the MGH Department of Medicine senior author of the report
along with saturated fats--has led to a omega-6 to omega-3 ratio as high as 20 to 1. It is known that molecules produced by omega-6 metabolism can promote inflammation
The current study describes how crossbreeding the fat-1 mouse with another strain transgenic for the c. elegans gene fat-2
which converts monosaturated fats into omega-6s can produce mice expressing both c. elegans genes.
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
Littermates fed a identical diet high in saturated fats and carbohydrates and low in omega-6s had these differences in their muscle tissues:
Even when fed a high-carbohydrate fat-free diet both the Omega and fat-2 strains produced significant levels of both essential fatty acids.
Since our 2004 report on the fat-1 mouse our lab and many others have been working towards the generation of larger omega-3-producing animals--including pigs sheep
and volatile organic compounds (VOC) in their urine and this may increase their risk for cancer
This new study uncovers an indispensable ingredient to the long sought-after cloud formation recipe--highly oxidized organic compounds.
The air we breathe is chock-full of organic compounds tiny liquid or solid particles that come from hundreds of sources including trees volcanoes cars trucks and wood fires.
and these oxidized organic compounds are attracted unusually to each other. This remarkably strong association may be a big part of why organics are drawn really to sulfuric acid under modern polluted conditions Donahue said.
Grains of corn could be engineered to produce proteins that could be extracted and processed into medicine pharmaceuticals

#Soy-dairy protein blend increases muscle mass, study showsa new study published online in the Journal of Applied Physiology shows additional benefits of consuming a blend of soy
and dairy proteins after resistance exercise for building muscle mass. Researchers from the University of Texas Medical Branch found that using a protein blend of soy casein
and whey post-workout prolongs the delivery of select amino acids to the muscle for an hour longer than using whey alone.
This study sheds new light on how unique combinations of proteins as opposed to single protein sources are important for muscle recovery following exercise
when compared to whey alone as only the blended protein kept synthesis rates elevated three to five hours after exercise.
Because of the increased demand for high-quality protein this study provides critical insight for the food industry as a whole
With more and more consumers recognizing the importance of protein for their overall health and well-being the results of this study have particular relevance to a large segment of the population from the serious sports and fitness enthusiast to the mainstream consumer.
if consumption of a blend of proteins with different digestion rates would prolong amino acid availability and lead to increases in muscle protein synthesis after exercise.
The protein beverages provided to study subjects consisted of a soy-dairy blend 25 percent isolated Dupont Danisco SUPRO soy protein 50 percent caseinate 25 percent whey protein isolate)
or a single protein source (whey protein isolate). Muscle biopsies were taken at baseline and up to five hours after resistance exercise.
The protein sources were ingested one hour after exercise in both groups. The study demonstrates that consuming a soy-dairy blend leads to a steady rise in amino acids the building blocks of muscle.
The data showed that the soy-dairy blend yields an increase in select amino acid delivery for about an hour longer than the use of whey protein alone.
The blend also sustained a greater positive net amino acid balance than whey suggesting there is less muscle protein breakdown during the time period shortly after consumption of a blended protein product.

#Synthetic gene circuits pump up cell signals in study of neurodegenerative diseasessynthetic genetic circuitry created by researchers at Rice university is helping them see for the first time how to regulate cell mechanisms that degrade the misfolded proteins implicated in Parkinson's Huntington
The Rice lab of chemical and biomolecular engineer Laura Segatori has designed a sophisticated circuit that signals increases in the degradation of proteins by the cell's ubiquitin proteasome system (UPS). The research appears online today in Nature Communications.
The UPS is essential to a variety of fundamental cellular processes including the cell cycle DNA repair immune response cell death and the degradation of misfolded and damaged proteins.
ubiquitin molecules that tag misfolded proteins for degradation and proteasomes that latch onto the tagged proteins and break them down into harmless peptides.
or they don't function properly misfolded proteins that remain floating in the cytoplasm can aggregate.
and chops up misfolded proteins. We know how to inhibit degradation but we want to find ways to activate it
because we think that will be useful to help prevent accumulation of misfolded proteins and aggregation
it essentially mimics a misfolded protein. Normally enhanced degradation would dampen the output signal but this genetic circuit makes it possible to link enhanced degradation to an increase in output.
They are the bottleneck in the high-yield production of recombinant proteins for example in cells engineered to crank up expression of a protein of interest Segatori said.

field study showsfor the first time a field test has demonstrated that elevated levels of carbon dioxide inhibit plants'assimilation of nitrate into proteins indicating that the nutritional quality of food crops is at risk as climate change intensifies.
but this is the first study to demonstrate that elevated carbon dioxide inhibits the conversion of nitrate into protein in a field-grown crop he said.
because plants use nitrogen to produce the proteins that are vital for human nutrition. Wheat in particular provides nearly one-fourth of all protein in the global human diet.
Many previous laboratory studies had demonstrated that elevated levels of atmospheric carbon dioxide inhibited nitrate assimilation in the leaves of grain and non-legume plants;
In the recent study the researchers documented that three different measures of nitrate assimilation affirmed that the elevated level of atmospheric carbon dioxide had inhibited nitrate assimilation into protein in the field-grown wheat.
which showed that there are several physiological mechanisms responsible for carbon dioxide's inhibition of nitrate assimilation in leaves Bloom said. 3 percent protein decline expectedbloom noted that other studies also have shown that protein concentrations in the grain
When this decline is factored into the respective portion of dietary protein that humans derive from these various crops it becomes clear that the overall amount of protein available for human consumption may drop by about 3 percent as atmospheric carbon dioxide reaches the levels anticipated to occur during the next few
Likewise when cows were fed protein contaminated with bovine prions many of them developed mad cow disease. On the other hand transmission of prions between species for example from cows sheep or deer to humans is--fortunately--inefficient and only a small proportion of exposed recipients become sick within their lifetimes.
Prions are misfolded toxic versions of a protein called Prp which in its normal form is present in all mammalian species that have been examined.
they can induce existing properly folded Prp proteins to convert into the disease-associated prion form.
The scientists introduced into mice the gene that codes for the normal bank vole prion protein thereby generating mice that express bank vole Prp but not mouse Prp.

Surprisingly they found that even large molecules such as proteins can be transported through these openings making a wide range of medications deliverable.
#UV exposure found to lower folate levels in young womenwomen who are pregnant or trying to fall pregnant and taking a folic acid supplement may be at risk of reducing their folate benefit through sun exposure a new QUT study has warned.
In a paper titled Exposure to solar ultraviolet radiation is associated with decreased folate status in women of childbearing age published in the Journal of Photochemistry and Photobiology B:
Biology QUT researchers found UV exposure significantly depleted folate levels. Professor Michael Kimlin and Dr David Borradale from QUT's Aussun Research Lab said the study of 45 young healthy women in Brisbane aged 18 to 47 showed high rates
of sun exposure accounted up to a 20 per cent reduction in folate levels. This is concerning as the benefits of folic acid are well-known with health professionals urging young women to take a folic acid supplement prior to
and during pregnancy Professor Kimlin said. Folate has been found to reduce miscarriage and neural tube defects such as spina bifida in unborn babies.
The NHMRC recommends pregnant women or those planning a pregnancy take 500 micrograms a day.
Professor Kimlin said the study which was the first to investigate the effects of sun exposure on folate levels in women of childbearing age found women who had high levels of sun exposure had folate levels below those recommended for women considering pregnancy.
The women at risk were those who were outside during the most UV intense time of the day between 10am
and the lowest levels of folate whilst not deficient in folate they were on the lower side of normal.
and folate depletion further research including a controlled clinical trial was needed. We are not telling women to stop taking folate supplements
but rather urging women to talk to their doctor about their folate levels and the importance of folate in their diet especially those who are planning a pregnancy Dr Borradale said.
The results of this study reinforce the need for adequate folate levels prior to and during pregnancy.
What is folate and how can I get it? Folic acid is A b vitamin that is very important for pregnant women and those planning a baby.
Folate is found in foods such as green leafy vegetables like spinach citrus fruits legumes whole grains and vegemite.
Folic acid is added also to many foods such as breads flours and pastas. Folic acid can also be taken as a pill.

and excretes damaged proteins and turns them into harmless peptides for disposal. The why is obvious:
how proteins perform the regulatory mechanisms in cells upon which life depends. The Rice team of biological physicist Josã Onuchic and postdoctoral researchers Biman Jana and Faruck Morcos published a new paper on the work this month for a special issue of the Royal Society
The paper describes the Onuchic group's first successful attempt to feed data through their computational technique to describe the complex activity of a large molecular machine formed by proteins.
Structural techniques like X-ray crystallography and nuclear magnetic resonance have worked quite well to help us understand how smaller proteins function Onuchic said.
X-rays only take snapshots of constantly moving proteins he said but functional proteins big protein complexes and molecular machines have multiple conformations.
Computational models are also useful but to understand the full dynamics of these large proteins where a lot of the interesting biology takes place we have to supplement them with more information he said.
That information comes from direct coupling analysis (DCA) a statistical tool developed by Morcos and Onuchic with colleagues at the University of California San diego and the Pierre and Marie Curie University.
DCA looks at the genetic roots of proteins to see how amino acids--the beads in the unfolded protein strands--co-evolved to influence the way a protein folds.
Even after they fold proteins are in perpetual motion acting as catalysts for countless bodily functions.
One such biomachine is Ftsh a membrane-bound molecule in E coli made of six protein copies that form two connected hexagonal rings.
and degrades misfolded proteins and other cellular detritus pulling them in through one ring which closes like the shutter of a camera and traps the proteins.
They are cut apart as they exit through the other ring. Through molecular simulations using structure-based models
and the discovery via DCA of likely couplings in the genetic source of the proteins the Rice team found evidence to support the hypothesis of a paddling mechanism in the molecule that Morcos described as a collapse of the two rings once trash found its way inside.
First the ring pore closes to grab the protein; then the molecule flattens he said.
We can look at the evolutionary tree of these proteins and see which pairs of amino acids changed together.
and we had crystallographic data for this motor protein in the 1990s there weren't enough sequences available until the 2000s Morcos said.
He said understanding essential motor proteins in bacteria will be important as researchers begin to apply DCA to advance human health.
