Since diet can influence insulin activation the researchers wondered whether diet could impact breast cancer prognosis based on expression of the IGF1 receptor in the primary breast tumor tissue.
This is the first study to suggest that it might be possible to personalize recommended diets for breast cancer survivors based on the molecular characteristics of their primary tumor.

When crops are pollinated adequately on the other hand the plants bear more fruit and their nutrient content changes.
In the case of several almond trees they combined the various manipulations in order to study in isolation and in combination the effects on harvest yield and the composition of nutrients in the nuts.
This led the scientists to the conclusion that an almond tree can compensate for a lack of nutrients
and water in the short term by directing stored nutrients and water to the fruits but cannot compensate for insufficient pollination.
Furthermore the scientists demonstrated that the composition of nutrients differs depending on the pollination mode: Nuts from the self-pollinated trees contained a lower proportion of linoleic acid but a higher proportion of Vitamin e.

However many agricultural lands are deficient in nitrogen leading farmers to rely on fertilizers to supply the needed nutrient for their crops.
The practice ensures that the land can continue to produce high-yield crops without resorting to adding fertilizers or other artificial methods of providing nutrients to the soil.

.--which came first the chicken or the egg? After consideration Aristotle decided that both the egg
and the chicken had existed always. That was not the right answer. The new Oregon State university research is providing a little more detail.
The study published in Proceedings of the Royal Society B actually attempts to explain the existence of what scientists call serial homologues
and across vast numbers of species. Repeated vertebra that form a spinal column rows of teeth and groups of eyespots on butterfly wings are all examples of serial homologues.
Put another way it's easier to see how one breed of chicken evolved into a different breed of chicken rather than where chickens
--or their eggs--came from to begin with. Butterfly wings are helping to answer that question. These eyespots common to the butterfly Family nymphalidae now serve many butterflies in dual roles of both predator avoidance and mate identification.

#Science of school lunch: Pictures tell story about lunch policies, healthy consumptionin terms of ambience Charlotte Central's cafeteria is--well conjure up your own elementary school lunch experience.
There's more than one reason to run to recess. But on a recent visit to observe a group of researchers from UVM's Johnson Lab the lunch ladies were serving up something more likely to be found on a restaurant menu:
risotto with mushrooms and peas. It's the result of a host of programs by schools around Vermont to offer more tempting choices--with locally sourced ingredients
when possible including herbs and vegetables from the playground garden--and to get children to eat more healthfully.
But is it working? That's what Rachel Johnson Robert L. Bickford Jr. Green and Gold Professor of Nutrition and Food Sciences along with her research team is trying to find out.
And they aren't alone in their concern. Since Fall 2012 USDA regulations require students across the country to take a fruit
or vegetable with their lunch a good intention that might easily go to the garbage. To get answers about

Straw contains a mix of sugars that could be used as a source of biofuels that do not compete with food production
However the sugars are in a form that makes them inaccessible to the enzymes that release them for conversion into biofuels so pre-treatments are needed.
and his team have been looking at the steps needed to unlock the sugars tied up in the tough straw structure In particular they have looked at the pre-treatment stage focusing on steam explosion
what effects varying the pre-treatments had on the different types of sugars before and after saccharification.
Saccharification efficiency is associated also with the loss of specific sugars and subsequent formation of sugar breakdown products.
The final sugar yield was closely related to the removal of xylan a common component of plant cell walls.
The abundance of lignin a'woody'cell wall component was positively related to the amount of available sugars.
#Poor diet before pregnancy linked with preterm birthuniversity of Adelaide research has confirmed for the first time that women who eat a poor diet before they become pregnant are around 50%more likely to have a preterm birth than those on a healthy diet.
It's the first study of its kind to assess women's diet prior to conception and its association with outcomes at birth.
and sugar foods and takeaway were about 50%more likely to have a preterm birth.
In our study women who ate protein-rich foods including lean meats fish and chicken as well as fruit whole grains and vegetables had significantly lower risk of preterm birth.
On the other hand women who consumed mainly discretionary foods such as takeaway potato chips cakes biscuits and other foods high in saturated fat and sugar were more likely to have born babies preterm Dr Grieger says.
It is important to consume a healthy diet before as well as during pregnancy to support the best outcomes for the mum and baby Dr Grieger says.
Diet is an important risk factor that can be modified. It is never too late to make a positive change.
We hope our work will help promote a healthy diet before and during pregnancy. This will help to reduce the number of neonatal deaths

#Low-carb vegan diet may reduce heart disease risk, weightresearchers at St michael's Hospital have shown for the first time that
The diet often called Eco-Atkins is a low-carbohydrate vegan diet. Many low-carbohydrate diets have been proven to improve weight loss
but most emphasize eating animal proteins and fats which may raise cholesterol. Diets that are high in vegetable proteins
and oils may reduce the risk of heart disease by lowering bad cholesterol. We killed two birds with one stone
We designed a diet that combined both vegan and low-carb elements to get the weight loss and cholesterol-lowering benefits of both.
The findings which were published in British Medical Journal Open compared Eco-Atkins to a high-carbohydrate low-fat diet.
The Eco-Atkins diet reduced cholesterol by 10 per cent while also helping participants lose an average of four more pounds than the high-carbohydrate low-fat diet over six months.

Rather than requiring fixed meals the menus served as a reference guide and participants were given a list of suitable food alternatives.

--which helped to encourage adherence to the diet. Twenty-three obese men and women completed the six-month diet.
Proteins came from gluten soy vegetables nuts and cereals. Predominant fat sources for the Eco-Atkins diet were nuts vegetable oils soy products and avocado.

It is possible to predict whether the parasitoid will lay a son or daughter by observing the presence
A pause means the egg will be fertilized. Conversely the absence of a pause means the egg will not be fertilized.
To know whether this particular behaviour is modified by climate the researcher exposed female Trichogramma to three different temperatures:
but the eggs were fertilized not after all. There were therefore more males produced at low temperature. Increasing fitnessin insects fitness is correlated positively with the size of an individual
whether there is an effect of phenological asynchrony between parasitoids and their hosts and therefore an impact on the availability of host eggs and on pest control by their natural enemies.
