Auto-injector developed for women undergoing fertility treatment

A new auto-injector concept has been designed by innovative product development firm Cambridge Consultants in a bid to ease the trauma for women undergoing fertility treatment.

Caltech-led team discovers enzyme responsible for neural crest cell development

During the early developmental stages of vertebrates-animals that have a backbone and spinal column, including humans-cells undergo extensive rearrangements, and some cells migrate over large distances to populate particular areas and assume novel roles as differentiated cell types.

Research roundup: Lowering health costs of the poorest sick; Local variations in health spending

Olmstead County, Minn., which earlier required just restaurants to be smoke-free, enacted a law in 2007 that banned smoking in all workplaces. Researchers reported "a substantial decline in the incidence of MI from 18 months before the smoke-free restaurant law was implemented to 18 months after the comprehensive smoke-free workplace law was implemented 5 years later.

Scientists find new way to unlock cells' destinies

Scientists have discovered that breaking a biological signaling system in an embryo allows them to change the destiny of a cell.

Technology creates 3-D map of stresses linked to malformed structures

Researchers at Case Western Reserve University have found a way to create three-dimensional maps of the stress that circulating blood places on the developing heart in an animal model - a key to understanding triggers of heart defects.

IVF process negatively impacts women’s sexual relationships

An Indiana University study has found that women undergoing in-vitro fertilization report that the process of infertility treatment has many negative impacts on their sexual relationship with their partner. Little attention has been given to the sexual dynamics of couples as they navigate infertility and treatments such as IVF, despite the important role that sex plays in a couple's attempt to conceive a child.

Idea of nuclear reprogramming holds promise for repairing damaged tissue

The idea of taking a mature cell and removing its identity (nuclear reprogramming) so that it can then become any kind of cell, holds great promise for repairing damaged tissue or replacing bone marrow after chemotherapy.

Zebrafish model can test unique individual genetic differences in humans

The zebrafish is a potential tool for testing one class of unique individual genetic differences found in humans, and may yield information helpful for the emerging field of personalized medicine, according to a team led by Penn State College of Medicine scientists. The differences, or mutations, in question create minor changes in amino acids -- the building blocks of DNA -- from person to person.

Lipid droplets play an unexpected role in embryo development

Histones are proteins needed to assemble DNA molecules into chromosomes. They have long represented a classic balancing act in biology; too few histone molecules result in DNA damage, while too many histones are toxic to the cell. New research at the University of Rochester is causing a fundamental shift in the concept of histone balance and the mechanism behind it.

Scientists resolve new molecular circuit controlling cellular metabolism

Cancer, diabetes, and excess body weight have one thing in common: they alter cellular metabolism. Scientists from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg and the Medical University of Vienna together with an international research team have jointly resolved a new molecular circuit controlling cellular metabolism.

Recombinant protein may treat male factor fertility

Male factor infertility resulting in failed oocyte activation from dysfunctional sperm phospholipase C-zeta may be remedied through the use of a recombinant form of the protein, leading to efficient blastocyst formation, say scientists.

Gene-silencing mechanism may occur later in life and lead to cancer

There are some genes that are only activated in the very first days of an embryo's existence. Once they have accomplished their task, they are shut down forever, unlike most of our genes, which remain active throughout our lives. EPFL scientists have unveiled part of this strange mechanism. The same process, accidentally initiated later in life, could be responsible for many kinds of cancer.

Optics Express publishes new paper on smart micromanipulation aided robotic-surgical tool

Even the most skilled and steady surgeons experience minute, almost imperceptible hand tremors when performing delicate tasks. Normally, these tiny motions are inconsequential, but for doctors specializing in fine-scale surgery, such as operating inside the human eye or repairing microscopic nerve fibers, freehand tremors can pose a serious risk for patients.

Study finds new regulator for heart formation

A new regulator for heart formation has been discovered by studying how embryonic stem cells adjust the packaging of their DNA. This approach to finding genetic regulators, the scientists say, may have the power to provide insight into the development of any tissue in the body - liver, brain, blood and so on.

Male BMI effects embryo quality, IVF outcome

Male body mass index influences pregnancy outcome in couples undergoing in vitro fertilization through its effect on embryo quality rather than on sperm parameters, report researchers.

Conceptually novel mechanism for biological regulation of cell suicide

Death plays a big role in keeping things alive. Consider the tightly orchestrated suicide of cells--a phenomenon essential to everything from shaping an embryo to keeping it free of cancer later in life. When cells refuse to die, and instead multiply uncontrollably, they become what we call tumors. An intricate circuitry of biochemical reactions inside cells coordinates their self-sacrifice. Tracing that circuitry is, naturally, an important part of cancer research.

Adding missing protein to infertile human sperm can 'kick-start' its ability to fertilise eggs

Adding a missing protein to infertile human sperm can 'kick-start' its ability to fertilise an egg and dramatically increase the chances of a successful pregnancy, a team of Cardiff University scientists have uncovered.

Researchers develop cranial neural crest cell lines

Researchers have successfully developed a stable population of neural crest cells derived from mice that can be grown in large quantities in the laboratory and that demonstrates the potential to develop into many different cell types needed throughout the body.

EmbryoScope Time-lapse system identifies abnormal development events in embryos

Which embryos have the best opportunity to develop into a viable pregnancy? A new technology provides a surprising answer. A major challenge in the field of IVF is selecting the single best embryo which is likely to result in a live birth. Currently, embryologists must remove the embryo from a standard incubator to perform 2 or 3 short evaluations of the developing embryo under the microscope, at fixed time-points over 3-5 days, in order to assess embryo quality prior to transferring an embryo to the patient.

Researchers obtain first detailed and complete picture of PRC2 protein

The first detailed and complete picture of a protein complex that is tied to human birth defects as well as the progression of many forms of cancer has been obtained by an international team of researchers led by scientists with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab).
