Obesity maybe passed down from fathers to kids: Study

Australian researchers have found that the sperm of overweight fathers appears to carry a molecular signal that causes their offspring to inherit obesity. This may be more severe in female children and males they add.

Scientists identify cellular protein that plays central role in formation of new blood vessels

Scientists at the University of North Carolina at Chapel Hill School of Medicine have identified a cellular protein that plays a central role in the formation of new blood vessels.

Scientists use genetic methods to successfully repair cleft lips in mice embryos

Scientists at Weill Cornell Medical College used genetic methods to successfully repair cleft lips in mice embryos specially engineered for the study of cleft lip and cleft palate. The research breakthrough may show the way to prevent or treat the conditions in humans.

Scientists discover genetic mechanism behind finger malformation

Scientists from the EPFL and the University of Geneva have discovered a genetic mechanism that defines the shape of our members in which, surprisingly, genes play only a secondary role. The research published in Cell, online the 23rd of November, shows the mechanism is found in a DNA sequence that was thought, incorrectly, to play no role.

Researchers identify protein that affects production of extracellular vesicles

Researchers at NYU Langone Medical Center have discovered a protein called TAT-5 that affects the production of extracellular vesicles, small sacs of membrane released from the surface of cells, capable of sending signals to other cells.

Researchers discover human genes that might contribute to ALS

Amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, is a universally fatal neurodegenerative disease. Mutations in two related proteins, TDP-43 and FUS, cause some forms of ALS. Specifically, these two proteins are RNA-binding proteins that connect to RNA to regulate the translation of proteins and other cellular functions such as RNA splicing and editing. In a new study, researchers at the Perelman School of Medicine at the University of Pennsylvania discovered additional human genes with properties similar to TDP-43 and FUS that might also contribute to ALS.

Cultured ES cells can self-organize into three-dimensional tissue-like structures

The possibility that functional, three-dimensional tissues and organs may be derived from pluripotent cells, such as embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs), represents one of the grand challenges of stem cell research, but is also one of the fundamental goals of the emerging field of regenerative medicine.

Fascin protein may play a critical transformation role in TGF beta mediated tumor metastasis

A protein called "fascin" appears to play a critical transformation role in TGF beta mediated tumor metastasis, say researchers at Moffitt Cancer Center in Tampa, Fla., who published a study in a recent issue of the Journal of Biological Chemistry.

Tufts University professor earns March of Dimes Foundation award for tissue development

A new approach to studying tissue development has earned Catherine K. Kuo, Ph.D., an assistant professor of biomedical engineering in Tufts University's School of Engineering, the Basil O'Connor Starter Scholar Award from the March of Dimes Foundation.

Reuters examines reproductive health issues in Russia

Reuters examines abortion, contraception and sex education in Russia, where, "two decades after the Soviet Union's collapse, wider availability of contraception and a resurgence of religion have reduced the numbers of abortions overall, but termination remains the top method of birth control in Russia."

Assisted reproduction rates rise and multiple births decline: Australian report

Latest reports from the Australian Institute of Health and Welfare show that the number of Australian and New Zealand women giving birth to twins after becoming pregnant with the help of assisted reproductive technology has reduced and may continue its declining trend.

State roundup: Puerto Rico settles disability battle with Feds

Puerto Rico has reached an agreement with the U.S. government ending a 12-year legal battle to improve the island's health system for the mentally disabled, local justice officials said Thursday. Federal officials had accused the U.S. territory of abusing and neglecting hundreds of mentally disabled people by not providing food, medication, adequate housing, therapy or mental health care.

Study reveals new role for the 'hormone of love'

Much of the body's chemistry is controlled by the brain - from blood pressure to appetite to food metabolism. In a study published recently in Developmental Cell, a team of scientists led by Dr. Gil Levkowitz of the Weizmann Institute has revealed the exact structure of one crucial brain area in which biochemical commands are passed from the brain cells to the bloodstream and from there to the body. In the process, they discovered a surprising new role for the 'hormone of love,' showing that it helps to direct the development of this brain structure.

One embryo is all it takes for a successful IVF: Study

Doctors practicing IVF often transferred multiple embryos to a woman’s body at once, in the hope that at least one of them would lead to a successful pregnancy. That changes now as a new study from researchers at the University of Iowa in Iowa City found that women who had only one embryo transferred during IVF didn’t have lower chances of getting pregnant, but they did have a lower risk of giving birth to twins than women who had multiple embryos transferred.

Researchers identify facial characteristics of children with autism

The face and brain develop in coordination, with each influencing the other, beginning in the embryo and continuing through adolescence. Now, University of Missouri researchers have found distinct differences between the facial characteristics of children with autism compared to those of typically developing children.

Embryonic stem cell therapy patents knocked back in Europe

The European Union's highest court ruled Tuesday that scientists cannot patent stem cell techniques that use human embryos for research, a decision some scientists said could threaten major medical advances if it prevents biotech companies from turning a profit.

High glucose and oxidative stress stimulate AMPK in embryo

In a paper published today in Diabetologia, a team at Joslin Diabetes Center, headed by Mary R. Loeken, PhD, has identified the enzyme AMP kinase (AMPK) as key to the molecular mechanism that significantly increases the risk of neural tube defects such as spina bifida and some heart defects among babies born to women with diabetes.

Scientists discover enzyme that acts as a 'fertility switch'

Scientists have discovered an enzyme that acts as a 'fertility switch', in a study published in Nature Medicine today. High levels of the protein are associated with infertility, while low levels make a woman more likely to have a miscarriage, the research has shown.

ESCs express genes linked with early germ cell specification

Ordinarily, embryonic stem cells exist only a day or two as they begin the formation of the embryo itself. Then they are gone. In the laboratory dish, however, they act more like perpetual stem cells - renewing themselves and exhibiting the ability to form cells of almost any type, a status called totipotency.

Current ultrasound guidelines for detection of miscarriage may lead to wrong diagnosis

Current guidelines that help clinicians decide whether a woman has had a miscarriage are inadequate and not reliable, and following them may lead to the inadvertent termination of wanted pregnancies. This is the conclusion of a series of papers published in the international journal Ultrasound in Obstetrics and Gynecology.
