Bioethicists lead call for public debates on future uses of stem cells

More than 40 scientists, bioethicists, lawyers and science journal editors are calling on their colleagues, policy makers and the public to begin developing guidelines for the research and reproductive use of stem cell-derived eggs and sperm, even though such use may be a decade or more away.

Women with cystic fibrosis can have safe and successful fertility treatment

Women with cystic fibrosis can have fertility treatment to help them have babies without any long-term adverse effects on either themselves or their children, according to new research presented at the 25th annual meeting of the European Society of Human Reproduction and Embryology in Amsterdam today (Tuesday).

Carbon nanotubes continue to show promise in battle against cancer

Carbon nanotubes, one of the original engineered nanomaterials, also may prove to be among the most versatile, as numerous teams of investigators continue to develop novel nanotube-based therapeutic and diagnostic tools. Over the past month, three new research papers have highlighted the potential of nanotubes as weapons against cancer.

Americans come up with first swine flu vaccine

The company based in Connecticut, Protein Sciences Corporation, won a $35-million government contract to develop an influenza vaccine using insect cell technology and Protein Sciences's director Dan Adams says the first batch of about 100,000 doses were produced last week and the manufacture of the vaccine continues.

A new take on growth factor signaling in tamoxifen resistance

Differences in growth factor (GF) signaling may cause the poor prognosis in some breast cancer cases. A new study, published in the open access journal BMC Medical Genomics, suggests that some estrogen receptor-positive breast cancers respond poorly to tamoxifen because of increased GF signaling.

Women warned not to wait too long to have a baby

Women are being warned that they should consider starting a family before the age of 35 or they will risk missing out on motherhood.

Fallopian tubes: a new source of multipotent adult mesenchymal stem cells

Human tissues normally discarded after surgical procedures could be a rich additional source of stem cells for regenerative medicine. New research from BioMed Central's open access Journal of Translational Medicine shows for the first time that human fallopian tubes are abundant in mesenchymal stem cells which have the potential of becoming a variety of cell types.

GPs have an opportunity to help infertile couples say North-East scientists

A major study into infertility in the UK has found that GPs could save years of anguish and heartache for couples desperate to have children.

Single gene found to control growth of some cancers

Research led by Ashok Aiyar, PhD, Associate Professor of Microbiology at LSU Health Sciences Center New Orleans, showing that a single gene can control growth in cancers related to the Epstein-Barr virus and that existing therapeutics can inactivate it, will be published in the June 12, 2009 online issue of PLoS Pathogens.

Cancer vaccine efficacy enhanced using anti-diabetic drug Metformin

After a vaccination or an infection, the human immune system remembers to keep protecting against invaders it has already encountered, with the aid of specialized B-cells and T-cells. Immunological memory has long been the subject of intense study, but the underlying cellular mechanisms regulating the generation and persistence of long-lived memory T cells remain largely undefined. Now, University of Pennsylvania School of Medicine researchers have found that a common anti-diabetic drug might enhance the effectiveness of vaccines. The findings are described this week in an advanced online publication of Nature.

Oxidative stress strongly evident in the in-utero environment of the fetus with Down syndrome

A paper published in the Proceedings of the National Academy of Sciences by Tufts Medical Center and Tufts University researchers reports that amniotic fluid surrounding Down syndrome fetuses shows oxidative stress, a condition that could harm fetal cells and play a role in affected individuals. The results demonstrate secondary adverse consequences of Down syndrome and suggest potential prenatal therapies.

New method to induce protein folding

A new method to induce protein folding by taking the pressure off of proteins is up to 100 times faster than previous methods, and could help guide more accurate computer simulations for how complex proteins fold, according to research by a team of University of Illinois scientists accepted for publication in the journal Nature Methods and posted on the journal's Web site May 31.

Combination of gene therapy and induced pluripotent stem cells cure human genetic disease in vitro

A study led by researchers at the Salk Institute for Biological Studies, has catapulted the field of regenerative medicine significantly forward, proving in principle that a human genetic disease can be cured using a combination of gene therapy and induced pluripotent stem (iPS) cell technology. The study, published in the May 31, 2009 early online edition of Nature, is a major milestone on the path from the laboratory to the clinic.

Worldwide increase in assisted reproduction

Assisted reproductive technology (ART) is responsible for an estimated 219,000 to 246,000 babies born each year worldwide according to an international study. The study also finds that the number of ART procedures is growing steadily: in just two years (from 2000 to 2002) ART activity increased by more than 25%.

QIAGEN launches novel product enabling non-invasive prenatal diagnostics and cancer detection

QIAGEN today announced the launch of a novel product for extraction of free circulating fragments of tumor- and fetal-derived nucleic acids as well as viral nucleic acids in human blood. Scientists consider these DNA and RNA fragments to have great potential for the highly sensitive and non-invasive diagnosis of a wide range of diseases, including congenital disorders, malignancies such as colon and lung cancer, and infections.

Life is tough for IVF twins early on

Australian researchers have found that twins conceived as a result of in-vitro fertilisation (IVF) do it tough, especially early in life.

Novel method stimulates growth of new neurons in adult brain

University at Buffalo researchers have identified a new mechanism that plays a central role in adult brain stem cell development and prompts brain stem cells to differentiate into neurons.

Twins born after fertility treatment have a higher risk of problems at birth and in the first three years of life

Twins born as a result of assisted reproductive technology (ART) are more likely to be admitted to neonatal intensive care and to be hospitalised in their first three years of life than spontaneously conceived twins, according to new research published online today (Wednesday 20 May) in Europe’s leading reproductive medicine journal Human Reproduction.
