#Fruit and vegetable intake is associated with lower risk of ER-breast cancerthere is no association between total fruit
and vegetable intake and risk of overall breast cancer but vegetable consumption is associated with a lower risk of estrogen receptor-negative (ER-)breast cancer according to a study published January 24 in the Journal of the National Cancer
and are less dependent on estrogen levels than ER+tumors account for only 15-20%of breast cancers large pooled analyses are needed to determine the suspected link to lower ER-breast cancer risk and the consumption of fruits and vegetables.
In order to determine if there is a link between the lowered risk of ER-breast cancers and the intake of fruits and vegetables Seungyoun Jung Sc.
and vegetables and risk of developing breast cancer in each study and then combined the study-specific estimates to generate summary estimates for all studies combined.
and vegetable intake was linked statistically significantly to a lower risk of ER-breast cancer but not with risk of overall breast cancer or risk of ER+breast tumors.
The results showed that the lower risk was associated mostly with higher vegetable consumption. These findings support the value of examining etiologic factors in relation to breast cancer characterized by hormone receptor status in large pooled analyses
(and to a lesser extent fruit) to lower the risk of ER-breast cancer. However they also write that interpretation of these findings may also be challenged by the known effects of other potential confounders including the aggregation of health behaviors.

#Beta carotene may protect people with common genetic risk factor for type-2 diabetesstanford University School of medicine investigators have found that for people harboring a genetic predisposition that is prevalent among Americans beta carotene
which the body converts to a close cousin of Vitamin a may lower the risk for the most common form of diabetes
The scientists used a big data approach to hunt down interactions between gene variants previously associated with increased risk for type-2 diabetes
and blood levels of substances previously implicated in type-2 diabetes risk. In people carrying a double dose of one such predisposing gene variant the researchers pinpointed a highly statistically significant inverse association of beta carotene blood levels with type-2 diabetes risk along with a suspiciously high positive association of gamma
tocopherol with risk for the disease. Type-2 diabetes affects about 15 percent of the world's population
whether beta carotene and gamma tocopherol are respectively protective and harmful themselves or merely markers whose blood levels dovetail with the presence
Moreover the fact that both beta carotene and gamma tocopherol interact with the same gene variant to influence diabetes risk
This in turn triggers the release of insulin whose adequate secretion by the pancreas and efficient uptake in muscle liver and fat tissue counters the dangerous buildup of glucose in the blood and in the long run the onset of type-2 diabetes.
The genomes of some 50 to 60 percent of the U s. population carry two copies of that very gene variant which previous studies have shown to confer a slightly increased risk of contracting type-2 diabetes.
While plenty of genetic risk factors for type-2 diabetes have been found said Butte none of them taken alone
None of the genetic factors studied in isolation had shown a particularly impressive impact on type-2 diabetes risk.
High blood levels of gamma tocopherol appeared to be associated with increased risk for the disease.

#Human-tiger conflict: are overestimated the risks? A new study finds a complex web of factors increases perceived risk of tiger attack in the Sundarbans of Bangladesh.
Wildlife conservationists are well aware of the potential conflicts that exist between the endangered species they seek to protect and the human populations
which inhabit areas where the animals live. Carnivores such as tigers pose a risk to humans
and their livestock and can be killed because of this potential risk. Previous research has found that killing of animals can be motivated as much by social and psychological factors such as perception of danger as by any actual real risk posed by a species. A new study published in the Springer journal Human ecology has identified several key factors
which may contribute to perceptions of risk from tigers in a conservation area in Bangladesh.
The study by Chloe Inskip and her colleagues from the Durrell Institute of Conservation and Ecology in Kent UK and Wildteam Bangladesh is the first to use participatory risk mapping (PRM)
and in depth interviews to explore the wider socioeconomic context of human-tiger conflict. The survey was carried out around the Sundarbans mangrove forests of southwestern Bangladesh home to one of the world's largest remaining tiger populations.
Although there are no human inhabitants of the Sundarbans eight sub-districts with a total population of around 1. 7 million people lie directly adjacent to the forest boundary.
Records indicate that approximately 30-50 people are killed annually by tigers in the area. The researchers held 54 semi-structured interviews in six villages which border the Sundarbans forest followed by 385 questionnaires in a further ten border villages.
Inskip and her colleagues identified the fact that these issues had a direct impact on villagers'perceptions of risk from tigers.
The respondents'perceived susceptibility to and their ability to mitigate human-tiger conflict was influenced largely by their poverty related-problems.
The authors suggest that any actions taken to improve these socioeconomic issues will also reduce the perceived level of risk from tigers
For conservationists this would mean a shift from traditional models of conflict reduction to holistic models which also incorporate situation-specific actions to reduce risk perceptions.
In many poor rural communities in conservation areas such as the Sundarbans risk perception reduction is likely to be tied strongly to poverty alleviation.
if the human dimensions and social context of human-wildlife conflict situations are understood well and appropriately managed.
They conclude that participatory risk mapping (PRM) and qualitative research are valuable tools for enhancing understanding of
and identifying actions to address the wildlife-related risk perceptions which can influence killing behavior.
Addressing risk perceptions will require long-term commitment and funding. Story Source: The above story is provided based on materials by Springer Science+Business Media.

Metabolic syndrome refers to a group of risk factors that occur together doubling the risk for heart disease
and increasing the risk for diabetes at least fivefold. Risk factors include having a large waistline low levels of high-density lipoproteins (HDL) or good cholesterol high blood pressure as well as high fasting blood sugar (insulin resistance) and high triglyceride levels.
According to the Centers for Disease Control and Prevention metabolic syndrome affects 35 percent of American adults over age 20.
'It also suggests that abnormal protein levels may be an early indicator to identify those at risk for developing metabolic syndrome.
