(Press-News.org) Jerusalem, Oct. 1, 2013 -- A new study by researchers at the Hebrew University of Jerusalem and Tel Aviv University reveals that eating a good breakfast can have a positive impact on women with problems of infertility.
In recent years, nutritional research has found that our weight is affected not only by the level of calorie intake, but also by the question of when to consume large amounts of calories.
Now, research, conducted by Prof. Oren Froy, director of the Nutrigenomics and Functional Foods Research Center at the Robert H. Smith Faculty of Agriculture, Food and Environment of the Hebrew University, and Ma'ayan Barnea, plus Prof. Daniela Jocabovitz and Dr. Julio Weinstein from Tel Aviv University and Wolfson Medical Center, shows that a big breakfast increases fertility among woman who suffer from menstrual irregularities.
The study examined whether meal times have an impact on the health of woman with menstrual irregularities due to Polycystic Ovary Syndrome (PCOS). PCOS affects approximately 6-10% of woman of reproductive age, disrupting their reproductive abilities. This syndrome creates a resistance to insulin, leading to an increase in male sex hormones (androgens), and can also cause menstrual irregularities, hair loss on the scalp though increase in body hair, acne, fertility problems and future diabetes.
The experiment was carried out at Wolfson Medical Center on 60 women over a 12-week period. The women, from the ages of 25 to 39, were thin with a BMI (body mass index) of less than 23 and suffered from PCOS.
The women were divided into two groups and were allowed to consume about 1,800 calories a day. The difference between the groups was the timing of their largest meal. One group consumed their largest meal, approximately 980 calories, at breakfast, while the other at dinner. Researchers wanted to examine whether the schedule of calorie intake affects insulin resistance and the increase in androgens among woman suffering from PCOS. The women kept records of exactly what they ate.
The findings, recently published in the journal, "Clinical Science," showed improved results for the group that consumed a big breakfast. Glucose levels and insulin resistance decreased by 8%, while the second group ("dinner") showed no changes. Another finding showed that among the "breakfast" group, testosterone (one of the androgens) levels decreased by nearly 50%, while the "dinner" group level stayed neutral. In addition, there was a much higher rate of ovulating woman within the "breakfast group" compared to the "dinner" group, showing that eating a hearty breakfast leads to an increase in the level of fertility among woman with Polycystic Ovary Syndrome.
According to Prof. Froy, "The research clearly demonstrates that indeed the amount of calories we consume daily is very important, but the timing as to when we consume them is even more important."

Body image impacts on weight gain during pregnancy
2013-10-01
How women perceive their bodies during pregnancy and how that impacts on their weight gain has been the subject of a new study by University of Adelaide researchers.
Researchers in the University's Robinson Institute and the School of Psychology have studied more than 400 South Australian women to better understand the links between body image and excessive weight gain during pregnancy.
The results, published in the journal Women and Birth, show that more than 70% of pregnant women who are overweight or obese under-estimate their weight. Those who under-estimate their ...
Scientists tap into spinal response from gastric reflux
2013-10-01
University of Adelaide researchers have made advances in the understanding of one of the world's most common medical conditions, gastric reflux, and how patients experience pain from it.
Gastric reflux affects as many as one in five people in Western countries and is on the increase in Asia. Diet and lifestyle, as well as genetic and hormonal issues, are commonly considered to be major causes of gastric reflux.
In laboratory studies, researchers have identified the nerve pathways in the spinal cord that transmit pain signals associated with gastric reflux to the brain.

CNIC researchers minimize damage during a heart attack with a drug costing less than €2.00
2013-10-01
The study, involving emergency ambulance services and teams at seven hospitals across Spain, shows categorically that this simple, low-cost strategy could easily be extended throughout the world, providing significant clinical benefit. This would change current practice for treating heart-attack patients, who currently receive no medication before undergoing angioplasty surgery, the recommended procedure for removing the arterial blockage that caused the infarction.
Borja Ibáñez—joint leading investigator on the study with Valentín Fuster—explains that clinical research ...
Macrophage-derived mediators may have potential as biomarkers for urinary stone risk
2013-10-01
Arnhem, 30 September 2013- A balance between the activation of the inflammatory macrophages and suppression of the anti-inflammatory macrophages in the kidney may play a pivotal role in kidney stone formation. These macrophage-derived mediators may have potential as biomarkers to reflect the urinary stone risk, according to a new study from Japan, which was recently presented at the recent 2nd Meeting of the EAU Section of Urolithiasis and received Clinical Research Award.
Compared to that of control subjects, the urine from individuals with a history of kidney stone formation ...
Restricting Voting Rights Act could mean fewer African-Americans on city councils
2013-10-01
Efforts to limit the reach of the Voting Rights Act of 1965 (VRA), the legislation that banned discrimination in voting, could negatively impact black political representation, according to a new study from researchers at Rice University, the University of Wisconsin-Milwaukee and Ohio University.
"Are We There Yet? The Voting Rights Act and Black Representation on City Councils, 1981-2006" is one of the first studies to take a "big picture" look at a large sample of city councils over time to see where African-Americans are making gains, where they are adding or losing ...
Variations in death rates after surgery for oesophageal and gastric cancers
2013-10-01
A pilot study has shown large variations between European countries in patient survival after surgery for oesophageal and gastric cancers. The 2013 European Cancer Congress (ECC2013) [1] will hear today (Tuesday) that the reasons for these differences are not clear and cannot be explained simply in terms of the volume of patients treated at each hospital.
Numerous previous studies have shown that hospitals that see and treat the highest numbers of patients for a variety of diseases and conditions ranging from cancer to cardiology tend to have greater expertise, resulting ...
Clinician observations of preschoolers' behavior help to predict ADHD at school age
2013-10-01
Don't rely on one source of information about your preschoolers' inattention or hyperactivity. Rather, consider how your child behaves at home as well as information from his or her teacher and a clinician. This advice comes from Sarah O'Neill, of The City College of New York, based on research she conducted at Queens College (CUNY), in an article published in Springer's Journal of Abnormal Child Psychology. The study examines how well parent, teacher, and clinician ratings of preschoolers' behavior are able to predict severity and diagnosis of attention deficit hyperactivity ...

New target to fight HIV infection identified
2013-10-01
A mutant of an immune cell protein called ADAP (adhesion and degranulation-promoting adaptor protein) is able to block infection by HIV-1 (human immunodeficiency virus 1), new University of Cambridge research reveals. The researchers, who were funded by the Wellcome Trust, believe that their discovery will lead to new ways of combatting HIV.
Professor Chris Rudd from the Department of Pathology, who led the research, said: "One exciting aspect about this new target for HIV intervention is that we should be able to fight HIV without compromising the immune system's ability ...
Gathering information about food is not top priority for individuals with high metabolisms
2013-10-01
New research has revealed that individuals with the highest metabolic rates within populations should be the least pre-occupied with keeping track of changes in their environments that could lead them to sources of food. Individuals with slower or average metabolisms however should be constantly monitoring their opportunities for higher gain when they are looking for food. The study shows that variation in metabolic rates between individuals can explain dramatic differences in information use when it comes to food.
The researchers, from the University of Exeter and the ...
