New insights into genesis and development of Sézary syndrome

Scientists at Charité - Universitätsmedizin Berlin, Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch, the Max-Planck-Institut für Molekulare Genetik Berlin, and four other German institutes succeeded in proving a specific gene loss in a certain human lymphoma, the genesis of which is largely unexplained to date.

IRCM geneticists discover an unsuspected organization of pituitary cells

A team of geneticists at the Institut de recherches cliniques de Montr-al (IRCM), directed by Dr. Jacques Drouin, made an unexpected discovery on hormone secretion. Contrary to common belief, the researchers found that pituitary cells are organized in structured networks. The scientific breakthrough was published yesterday by the scientific journal Proceedings of the National Academy of Sciences.

Dilemma of single vs. double embryo transfers

Elsevier announced the publication of several commentaries in the scientific journal Reproductive BioMedicine Online on the subject of how many embryos it is safe and proper to place in a uterus, and how best to regulate this decision. It is a dilemma faced by all patients anxiously caught between no pregnancies at all or facing the prospect of twins or triplets. In this difficult place it is often all too easy to think that the latter option must be the best. But is it?

Carcinogenesis is just another form of speciation, proposes new theory

Cancer patients may view their tumors as parasites taking over their bodies, but this is more than a metaphor for Peter Duesberg, a molecular and cell biology professor at the University of California, Berkeley.

World's best genetic map now built in African-Americans

A group of researchers from the University of Oxford, Harvard Medical School and the University of Mississippi Medical Center has constructed the world's most detailed genetic map, a tool scientists can use to better understand the roots of disease and how DNA is passed generationally to create diversity in the human species.

Being an alpha male stressful: Primate study

A nine year old tracking study of five troops of baboons in Kenya found that the top-ranked alpha males had more stress than the second-place beta males. In fact the top baboon was just as ‘on-edge’ as those unfortunate primates at the bottom of the pecking order. Thore Bergman, a biological psychologist at the University of Michigan who was not involved in the study said, “Being at the top may not be all it's cracked up to be.”

'Sex' between viruses can create new influenza pandemic

A new University of Maryland-led study finds that 'sex' between the virus responsible for the 2009 flu pandemic (H1N1) and a common type of avian flu virus (H9N2) can produce offspring -- new combined flu viruses -- with the potential for creating a new influenza pandemic.

Maternal smoking during pregnancy causes serious birth defects

To dispel any uncertainty about the serious harm caused by smoking to babies and pregnant women, the first-ever comprehensive systematic review of all studies over the past 50 years has established clearly that maternal smoking causes a range of serious birth defects including heart defects, missing/deformed limbs, clubfoot, gastrointestinal disorders, and facial disorders.

Study confirms link between phthalates and thyroid hormone levels in humans

A link between chemicals called phthalates and thyroid hormone levels was confirmed by the University of Michigan in the first large-scale and nationally representative study of phthalates and BPA in relation to thyroid function in humans.

Primary function of sex is not to promote diversity, but to maintain a species' identity

Biology textbooks maintain that the main function of sex is to promote genetic diversity. But Henry Heng, Ph.D., associate professor in WSU's Center for Molecular Medicine and Genetics, says that's not the case.

Researchers to evaluate long-term health effects of oil spills

An NIH-funded network of researchers will evaluate potential harmful effects of the Deepwater Horizon disaster on reproduction and birth outcomes, the cardiorespiratory system, and behavior and mental health.

Merck Serono announces recipients of second Grant for Fertility Innovation

Merck Serono, a division of Merck KGaA, Darmstadt, Germany, today announces the recipients of its second Grant for Fertility Innovation.

Tulane University receives NIH grant to examine oil spill effects on women's health

The NIH's National Institute of Environmental Health Sciences has awarded Tulane University School of Public Health and Tropical Medicine $6.5 million for a five-year study exploring the potential health impacts of the Deepwater Horizon disaster on pregnant women and women of reproductive age living in Louisiana's coastal parishes.

Smoking pregnant mums have smaller unhealthier babies

Professor Nick Macklon of Southampton University says even though most women now understand there is “overwhelming evidence” that smoking during pregnancy is harmful to the developing child, they continue to do so.

Gum disease linked to infertility

According to experts gum disease may reduce the chances of getting pregnant. Poor oral health is as bad for fertility as obesity - delaying conception by about two months says latest research.

Fiscal problems could be mitigated by ART conceived children

In 2009, 1,547 ART children were born in public clinics in Denmark, projecting a net tax revenue of -224 million and -247 million in 25 and 50 years respectively. The authors of the study calculated that reductions of 30-50% in ART cycles following the new policy would lead to cost savings of -67 - -111 million for the Danish government in 2034.

Cumulus cells can provide information about genetic and chromosomal status of eggs

At present, when a woman undergoes preimplantation genetic screening (PGS) in a fertility clinic, doctors are trying to select an egg or an embryo that is healthy and doesn't have a chromosome abnormality such as an extra copy of chromosome 21, which causes Down's syndrome. In order to establish this, they either have to biopsy a part of the egg called the polar body or remove a cell from the embryo for screening. Both procedures are expensive, invasive and can damage the egg or embryo.

Specialist RM clinic helps women achieve subsequent live birth

The researchers studied the records of 987 women with a minimum of three consecutive miscarriages, who had been referred to a specialist RM clinic between 1986 and 2008.

Study highlights importance of mRNA translation in aging process

When researchers at the Buck Institute dialed back activity of a specific mRNA translation factor in adult nematode worms they saw an unexpected genome-wide response that effectively increased activity in specific stress response genes that could help explain why the worms lived 40 percent longer under this condition.

Study: 'Vanishing twin' linked to increased risk of congenital malformations

Professor Michael Davies will tell the annual meeting of the European Society of Human Reproduction and Embryology today that the "vanishing twin" phenomenon, in which only one child is born from a pregnancy that originally starts as a multiple pregnancy, is linked to a nearly two-fold increased risk in any congenital malformation and to a nearly three-fold risk of multiple malformations.
