EU: Talks on Iran's nuclear program to continue

(AP) ? Iranian and international technical experts have exchanged details on proposals to end the standoff over Tehran's controversial nuclear program and a new meeting will be set soon, the European Union said Wednesday.

A statement said the Istanbul-based talks lasted a full day and ended early Wednesday.

The talks followed three rounds of negotiations between Iran and six world powers that have failed to produce a breakthrough.

At the last meeting in Moscow in June it was agreed to set up the experts level meeting, and ? if sufficient progress on bridging differences between the two sides was achieved ? to then have Iran's No. 2 nuclear negotiator Ali Bagheri meet with Helga Schmid, the EU official in charge of the talks.

It was agreed in Istanbul that the two officials would meet but no date has yet been set, said an official who could not be named under EU rules.

The meeting in Istanbul was led by nuclear expert Stephan Klement on behalf of EU foreign policy chief Catherine Ashton. The experts came from the six powers ? Britain, the United States, the European Union, China, France, Germany and Russia ? involved in the talks and collectively known as the E3+3.

The statement said the experts had met with the Iranian team, and "provided further detail of the E3+3 proposal given to Iran in Baghdad (while) Iran shared further detail of their proposal; and the experts explored positions on a number of technical subjects."

The EU, U.S. and other nations suspect Iran's nuclear program is aimed at developing atomic weapons. Iran denies this, and says it is for peaceful purposes, such as producing energy and medical isotopes.

Iran is already under four sets of U.N. sanctions and measures levied by the U.S and tried unsuccessfully to use the Moscow talks to get the sanctions eased.

An EU ban on Iranian oil came into full effect July 1, and analysts expect the sanctions to cut the crude exports of Iran, OPEC's second-largest producer.

The EU embargo, combined with the fresh measures that prohibit the world's banks from completing oil transactions with Iranian banks, significantly ratchet up the pressure on an Iranian economy already squeezed by previous rounds of sanctions.

New, more effective vaccines are struggling to have an impact in the drive to eradicate polio in Afghanistan and Pakistan because not enough children are being vaccinated, according to a study published in the Lancet medical journal today. Sharp declines in vaccine uptake led to a rise in the number of new infections between 2006 and 2011, even though new vaccines introduced during this time have proven to be more effective against the main circulating strain of the virus.

Poliovirus exists in three strains, with type 1 the most prevalent and type 2 unseen anywhere in the world since 1999. It mainly affects children under five and causes paralysis in about one in 200 cases. In most parts of the world it has been eliminated by sustained vaccination programmes in the late 20th century. Afghanistan and Pakistan are among only three countries along with Nigeria that have never managed to eliminate polio.

Since it was launched in 1988, the Global Polio Eradication Initiative (GPEI) spearheaded by national governments, the World Health Organization (WHO), Rotary International, the US Centers for Disease Control and Prevention (CDC) and UNICEF - has relied on mass campaigns using the trivalent oral poliovirus vaccine, which contains all three types of the virus,. However, the presence of the type 2 strain in the trivalent vaccine makes it less effective against the other types. In 2005, monovalent vaccines of types 1 and 3 were introduced by the GPEI and in 2009 a bivalent vaccine containing both types was first used.

Scientists from Imperial College London and the WHO assessed the effect of immunisation campaigns in the Afghanistan and Pakistan by analysing data collected by national surveillance programmes. They also assessed the effectiveness of the three varieties of polio vaccine against the predominant type 1 strain of the virus.

The study found that the monovalent vaccine was more effective than the trivalent vaccine against type 1 poliovirus. The bivalent vaccine was comparable in effectiveness to the monovalent vaccine. The difference between the bivalent and trivalent vaccines was not large enough to be statistically significant.

In 2006 over 80% of children in Afghanistan and Pakistan aged 0-2 years old received four doses or more of vaccine. However, vaccine coverage in southern Afghanistan and parts of Pakistan, including Balochistan and the Federally Administered Tribal Areas (FATA) declined from 2006 to 2011. Although the impact was partially offset by the use of the more effective vaccines, this resulted in significantly lower population immunity levels, leading to an increase in cases over that time frame. In 2011 there were 198 cases in Pakistan and 80 cases in Afghanistan compared with 40 cases in Pakistan and 31 in Afghanistan in 2006.

This analysis prompted a major shift in approaches in 2012 in both countries, to address the underlying challenges which prevent children from having access to polio vaccines. Both countries are this year implementing national polio emergency action plans, involving measures such as increasing technical support to the worst-performing areas; creating accountability mechanisms for district-level leadership; and engaging with communities to increase demand for immunisation.

"Our findings show it's not just small pockets where vaccine coverage decreased from 2006 to 2011," said Dr Kath O'Reilly, from the Medical Research Council (MRC) Centre for Outbreak Analysis and Modelling at Imperial College London, who led the study. "The new vaccines appear to be more effective than the trivalent vaccine, which offers encouragement that polio eradication is achievable. But the best vaccine in the world will not work unless it reaches the children its intended to protect. So it's vitally important that vaccine coverage is considerably improved in 2012 through better campaigns and routine programmes if we're to finally eradicate polio globally."

Shrews ?warm up? before cold dives

Thumb-sized shrews "warm up" their bodies before taking the plunge into cold water, according to researchers.

Scientists investigated how the shrews, known as the smallest diving mammals, coped with the challenges of diving.

Larger mammals are known to boost their chances of finding prey by staying cool to save energy and dive for as long as possible.

But the shrews raised their body temperature by up to 1.5C and took shorter dives in cold water.

"They were completely contrary to what we predicted," said Dr Kevin Campbell from the University of Manitoba, Winnipeg, Canada who presented the research at the Society for Experimental Biology's annual conference.

Continue reading the main story

A shrew's tale...

  • Deceptive looks: Despite looking like rodents shrews are in fact closer to moles than to mice
  • Tiny terrors: Common shrews have an insatiable appetite for insects and worms, devouring twice their own body weight in a single day
  • Ultrasonic squeaks: There are nearly 400 species of shrew including some of the very few terrestrial mammals known to echolocate
  • Venomous bite: The European water shrew is the UK's only venomous mammal... but is it the deadliest?

In the past, research into diving ability in mammals has focused on large species including seals and penguins.

But Dr Campbell and his colleagues wanted to look at the other end of the scale. They spent over a decade working with tiny American water shrews (Sorex palustris), which weigh a maximum of 17g.

The thumb-sized animals are known for their voracious appetite, consuming their entire body weight in prey every day in order to survive, and Dr Campbell described them as "the most effective, ruthless predators I have ever seen".

Although they live on land they frequently hunt underwater, diving to catch prey such as dragonfly nymphs, crayfish and snails.

Dr Campbell explained that according to existing knowledge, the shrews' diminutive size should make them unsuitable divers.

"Optimal foraging theory would say you want to stay underwater as long as you can because that increases your likelihood of finding food," he said.

"This is why most diving animals are large, because the larger you are, you carry more oxygen and you burn it at a slower rate."

What we're thinking is that they are increasing their body temperature to increase their sensory system?

End Quote Dr Kevin Campbell University of Manitoba

By comparing them with short-tailed shrews, the team found that water shrews do have relatively greater oxygen stores but Dr Campbell described them as "pushing the boundary of size for divers".

To fully understand how the tiny animals survive their lifestyle, the scientists wanted to know if they were sharing any other strategies with larger divers.

"Another thing you can do to dive longer is to let your body temperature drop a little because then your metabolism slows down," explained Dr Campbell.

To test for this the team used miniature implants to record the water shrews' body temperatures before, during and after diving.

Dr Campbell and his colleagues monitored how the shrews' body temperatures changed when diving in a variety of different water temperatures in a tank specially designed to simulate their wild habitat.

The warmest water was 30C, close to the shrews' normal body temperature, but the coldest water was just 3C, mimicking winter water temperatures in their native North America and Canada.

To their surprise, the scientists found that the animals did not employ the usual strategy of lowering their temperature, choosing instead to minimise their dives in cold water.

The animals sought prey just as frequently but spent less total time in the water and took shorter dives.

Dr Campbell explained that this could be because losing heat poses a much greater risk for the shrews.

"When you're tiny you get to that [critically low] temperature much quicker, so you're much more susceptible to hypothermia," he said.

Instead the shrews maintained their temperature and even employed the opposite tactic; sitting at the water's edge and warming up by 1.5C before diving into the coldest water.

According to scientists the shrews were achieving the heat boost by shivering or using "brown fat" - tissue found in many small mammals that can generate heat without them exercising.

"What we're thinking is that they are increasing their body temperature to increase their sensory system," said Dr Campbell.

The water shrews employ sophisticated senses of hearing and touch to make them efficient hunters.

They are even known to "smell" underwater, bubbling air from their nose close to potential prey before sucking it back in.

The researchers suggested any drop in temperature would have a negative impact on these systems.

"We think there's been a trade-off here for the little guys," said Dr Campbell.

"They're going for shorter dives but they're much more efficient."

A high intake of certain dietary fats associated with lower live birth rates in IVF

Istanbul, 3 July 2012: Women with a higher intake of dietary saturated fats have fewer mature oocytes available for collection in IVF, according to results of a study from the Harvard School of Public Health funded by the US National Institutes of Health. The study investigated the effect of dietary fat (classified as total, saturated, monounsaturated, polyunsaturated, omega 6, omega 3 and trans) on a range of preclinical and clinical outcomes in women having IVF. Results showed that the intake of saturated fat was inversely related to the number of mature oocytes retrieved, while polyunsaturated fat consumption was inversely associated with early embryo quality.(1)

Dietary fat intake has been previously studied for its effect on reproductive health; for example, a high intake of trans-fats has been associated with ovulatory infertility (as in polycystic ovary syndrome) and miscarriage, while saturated fats have been related to lower sperm concentrations. But so far little has been known about the effect of dietary fat intake on the outcome of fertility treatment.

The results of this study were presented today at the annual meeting of ESHRE (European Society of Human Reproduction and Embryology) by Dr Jorge Chavarro, Assistant Professor of Nutrition and Epidemiology at Harvard School of Public Health, USA.

The study took place among 147 women having IVF at the Massachusetts General Hospital Fertility Center. Preclinical assessments included oocyte development, fertilisation, embryo quality and cleavage rate, while clinical outcomes (pregnancy, live birth) were recorded in all women who had embryo transfer. The women were also categorised into tertiles of fat intake, with outcomes compared in relation to the lowest tertile. Results were controlled for other sources of energy, infertility diagnosis, ovarian stimulation protocol, body mass index (BMI) and smoking status.

Following statistical analysis it was found that women with higher intakes of total fat had fewer metaphase II (MII) oocytes retrieved than women in the lowest tertile. This association was driven by intake of saturated fat, said Professor Chavarro. Women in the highest tertile of saturated fat intake had on average 9.3 MII oocytes, while those with the lowest intake had 11.6 MII oocytes.

"Only MII oocytes can be used for IVF," he explained. "Thus, having fewer mature oocytes can mean fewer embryos to choose from for fresh transfer or future transfer following cryopreservation, particularly among women who respond poorly to ovarian stimulation."

Polyunsaturated fat consumption was found inversely related to embryo quality. Women in the highest tertile of polyunsaturated fat intake had a higher proportion of poor quality embryos and more slowly cleaving embryos than had women in the lowest tertile of intake.

Fat consumption was also associated with clinical outcomes. Higher intakes of monounsaturated fat were related to higher odds of live birth. The odds of a live birth after embryo transfer in women with the highest intake of monounsaturated fat were 3.45 times higher than those of women with the lowest intake.

"We were not entirely surprised that different types of fat were associated with different outcomes," said Professor Chavarro. "One advantage of assisted reproduction as a model for the study of human fertility is that it allows the examination of factors possibly related to interactions between the embryo and the endometrium independently of other factors related to early embryo development or ovarian response to stimulation.

"Different types of fat are known to have different effects on biological processes which may influence the outcome of assisted reproduction - such as underlying levels of inflammation or insulin sensitivity. However, it is not clear at this moment which biological mechanisms underlie the associations we found."

On the question of recommendations to IVF patients, Professor Chavarro said: "While these results are interesting, this is the first time to our knowledge that dietary fats have been linked to treatment outcome in IVF. So it is important that our results are replicated in other studies before making strong recommendations about fat intake to women having infertility treatment."

Notes

1. Mature oocytes - in a natural or stimulated cycle - are defined as having reached the metaphase II stage, a point of development in which the first polar body has formed. In a natural cycle the "leading" MII oocyte is ovulated, while in assisted reproduction several MII oocytes are collected for in vitro fertilisation. Development continues after fertilisation when the second polar body forms and the oocyte takes on its full complement of chromosomes.

Beats? Acquisition Of MOG Confirmed: The Aim Is A ?Truly End To End Experience?

beats headphonesLooks like the reports that have been in play for months now have finally been confirmed: Beats Electronics, known best for their hip Dr Dre headphones and partly backed by HTC (who had also been a rumored MOG buyer), is indeed buying the music streaming service MOG, with the acquisition now confirmed by both sides. The move will give MOG -- struggling to grow against the runaway success of Spotify -- a new lease of life tied to a specific hardware maker; and Beats another step up on the consumer electronics experience, following in the mold of Apple in providing the whole package from one brand. "The addition of MOG's music service to the Beats portfolio will provide a truly end-to-end music experience," David Hyman, the founder and CEO of MOG told USA Today. Although the deal has been in play since March of this year, this was in fact the first confirmation by either side that they are linking up. We're still contacting both companies for a direct confirmation.
