Researchers profile over 6000 genes in the two primary types of normal breast cells

For several years, scientists have attempted to identify gene expression changes, using microarrays or ‘DNA chips’, in order to understand and predict breast cancer onset, progression, and clinical outcome.

Discovery shows how single genetic mutation can cause complex disorders

Bardet-Biedl syndrome (BBS), characterized by obesity, learning disabilities and eye and kidney problems, is caused by genetic mutations in the BBS family of genes. Now, researchers who've long studied the condition have discovered that genetic mutations in one of those genes, called BBS4, lead to cell death by disrupting the cells' internal "highway" system.

Nitric oxide, a chemical messenger involved in bodily functions shuts down a protein involved in Parkinson's disease

Johns Hopkins researchers have discovered that nitric oxide, a chemical messenger involved in bodily functions from erection to nerves' communication, also shuts down a protein involved in Parkinson's disease.

Scientist discovers why skin turns leathery

“The reason our skin becomes more leathery and thick as we age might be due to a loss of elasticity in the cells,” says Igor Sokolov of Clarkson University, who presented his latest research findings during a session on bio-imaging techniques at the Annual American Physical Society (APS) March meeting in Montreal.

Infertile couples may be unaware of multiple birth risks

Multiple births -- twins, triplets or more babies in one pregnancy -- have more risks of infant death and long-term disabilities such as cerebral palsy than births of single babies do. However, many couples seeking infertility treatments desire multiples and have poor knowledge particularly about the risks for twins, a University of Iowa study reported.

FDA announces science-based approach to protecting Americans from unsafe dietary supplements

Speaking before the American Society for Pharmacology and Experimental Therapeutics (ASPET) and the American Society for Nutritional Sciences, Dr. Lester M. Crawford, Acting Commissioner of the Food and Drug Administration (FDA), today outlined the agency's science-based approach to protecting American consumers from unsafe dietary supplements.

Second-hand smoke scars and affects healing

Researchers at the University of California, Riverside have found that breathing “second-hand” smoke reduces the speed at which wounds heal, leading to greater levels of scarring.

First IVF embryo research licenses issued in Australia

Australia’s first licences allowing research using excess human embryos were issued today by the Embryo Research Licensing Committee of the National Health and Medical Research Council, (The NHMRC Licensing Committee).

Genetic mutation raises interesting questions about the evolution of the Y chromosome

The names and dates comprising a family tree contain branches that can extend backward centuries in time. People use these diagrams to discover their ancestral origin. Scientists use them to study the genealogical origins of entire species, tracing evolutionary history down to changes in a single gene.

Growth hormones combat Crohn’s disease, cardiac disorders and improve fertility in invitro fertilisation

New treatments for breast cancer, skin and wound healing and obesity will be revealed at an international conference in Cairns, Australia next week.

Antimicrobial alginate dressing protects the wound with silver

Johnson & Johnson Wound Management today announced the introduction of SILVERCEL™ antimicrobial alginate dressing, providing the protection of silver and the absorption of alginate.

Prosthetic heart valve made completely of the body’s own tissue

Eight out of every 1000 children are born with a heart problem. Out of these, every fifth child needs a heart valve. While today’s mechanical or biological heart valves allow children to continue their lives, a research team at RWTH is developing a significantly more compatible heart valve that grows along with the body’s growth.

New database for U.S. makers of in vitro diagnostic (IVD) medical devices

A new international database has been released that identifies measurement procedures and materials that will help U.S. makers of in vitro diagnostic (IVD) medical devices ensure that their products comply with European Union requirements.

New device filters blood supplies on-site reducing the possible transmission of Creutzfeldt-Jakob disease

ProMetic Life Sciences Inc. has announced today that its joint venture with the American Red Cross, Pathogen Removal and Diagnostic Technology Inc. ("PRDT"), has confirmed that treatment of TSE spiked red blood cell concentrate with its Prion Reduction Device results in a significant decrease in associated infectivity.

FDA Approves Pre-Filled Pre-Mixed Fertility Medication

The U.S. Food and Drug Administration (FDA) today announced approval of Follistim®-AQ TM cartridge (follitropin beta injection) in the United States. Follistim-AQ cartridge is the first follicle stimulating hormone (FSH) treatment available in a pre-filled, pre-mixed solution, eliminating the need for patients to mix one or more vials of medication.

Research suggests the orlistat drug could be used to fight cancer and obesity

The Burnham Institute’s Jeffrey Smith, Ph.D., has discovered that orlistat, commonly prescribed as an anti-obesity drug, has a positive side-effect: it inhibits cancer growth. Dr. Smith made this discovery using an activity-based proteomics screening technique developed in his laboratory that makes it possible to identify active targets and simultaneously screen for their inhibitors.
