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.

Genetics & IVF Institute now offers 24 Chromosome Microarray

The Genetics & IVF Institute is now offering 24 Chromosome Microarray, which is a new, comprehensive test used as part of an IVF cycle to evaluate the number of chromosomes present in an embryo before it is transferred to the mother.

New technique could give a preview of which eggs are likely to make the most viable embryos

Given the stakes of in vitro fertilization, prospective parents and their doctors need the best information they can get about the eggs they will extract, attempt to fertilize, and implant. New research at Brown University and Women & Infants Hospital of Rhode Island has found a way to see which genes each egg cell is expressing without harming it.

Thriving stem cells created by cloning technique

In a breakthrough that has been debated and awaited for long, scientists have finally derived colonies of embryonic stem cells from human embryos created using cloning technology.

Three Georgia Tech projects to receive NSF's EFRI grants

The National Science Foundation (NSF) has awarded $6 million to fund three projects involving researchers from the Georgia Institute of Technology. Each four-year, $2 million grant was awarded through the NSF's Division of Emerging Frontiers in Research and Innovation.

Lin28/let-7 pathway plays an unexpected key role in type 2 diabetes

A pathway activated in cancer plays an unexpected key role in metabolic diseases like type 2 diabetes, according to a study by researchers at Children's Hospital Boston. Evidence that the Lin28/let-7 pathway influences the cellular response to glucose provides a unifying theme to perplexing data that associates human genetic variation with diabetes risk.

Researchers analyse effects of BPA in an in-vitro culture of ovaries

Researchers at Universitat Aut-noma de Barcelona, in collaboration with the Vall d'Hebron Hospital Fetal Tissue Bank, the Department of Gynaecology and the Research Unit of Paediatric Endocrinology, analysed the effects of Bisphenol A (BPA), a polymer widely used to manufacture plastics, in an in vitro culture of ovaries.

Researchers show how the body rids itself of damage when needed to reproduce and create new life

Although the body is constantly replacing cells and cell constituents, damage and imperfections accumulate over time. Cleanup efforts are saved for when it really matters. Researchers from the University of Gothenburg, Sweden, are able to show how the body rids itself of damage when it is time to reproduce and create new life.

Scientists discover crucial connection in skin formation

Skin is the body's armor, protecting us from disease agents, injury, excessive water loss, and cold and heat. Yet mutations in a single gene, the gene for the protein p63, cause numerous diseases and malformations of the uppermost layer of skin - the epidermis - and other tissues. In the epidermis, these range from skin cancers to dysplasias that cause cracking, bleeding, infection, and discoloration.

Water plays a decisive role in biologically active enzyme substrate compounds

In biologically active enzyme substrate compounds, as can be found in medicines, water plays a more decisive role than has been imagined up to now. The surrounding water acts like an "adhesive", in order to keep the substrate at the right place on an enzyme.

Rac1 protein triggers growth of long 'legs' that could propel melanoma cells to spread

Cancer Research UK scientists have discovered that a protein called Rac1 prompts pigment cells to sprout long 'legs' that could propel skin cancer cells, allowing them to spread, according to research published in Developmental Cell today.

Single UV laser pulse simultaneously zaps away biological tissue at multiple points

Researchers at Vanderbilt University have developed a new technique that uses a single UV laser pulse to zap away biological tissue at multiple points simultaneously, a method that could help scientists study the mechanical forces at work as organisms grow and change shape.

Pancreatic mesenchyme plays central role in the formation of mature beta cells

A somewhat mysterious soft tissue found in the fetus during early development in the womb plays a pivotal role in the formation of mature beta cells the sole source of the body's insulin. This discovery, made by scientists at University of California, San Francisco (UCSF) and Texas A&M University, may lead to new ways of addressing Type 1 and Type 2 diabetes.

Scientists discover highly conserved mechanism governing brain development

If you think today's political rhetoric is overheated, imagine what goes on inside a vertebrate embryo. There, two armies whose agendas are poles apart, engage in a battle with consequences much more dire than whether the economy will recover---- they are battling for whether you (or frogs or chickens) will have a forebrain.
