New study points to new treatments for some forms of Lou Gehrig's disease

A new study indicates that mutant Cu/Zn superoxide dismutase (SOD1) enzymes that are associated with an inherited form of Lou Gehrig's disease cause the protein to become sticky in tissues. Partial unfolding of the mutant protein can expose hydrophobic residues that may promote abnormal interactions with other proteins or membranes in the cell.

Lifestyle changes may affect the progression of any type of cancer

Men with early stage prostate cancer who make intensive changes in diet and lifestyle may stop or perhaps even reverse the progression of their illness, according to a new study.

Genelabs drug discovery team advances compounds against the hepatitis C virus

Genelabs Technologies today announced that a non-nucleoside compound from its internal Hepatitis C virus (HCV) drug discovery program has advanced into preclinical development.

Strategic analyses of European In-Vitro cancer diagnostics market - Cancer research yields promising results

Every year, nearly one in four Europeans - a total of almost one million people - dies from cancer, giving Europe the dubious distinction of having amongst the highest cancer-related mortality rates in the world. Even as cancer remains a difficult disease to diagnose, often resulting in either poor diagnosis or misdiagnosis, the number of new cancer cases is set to double by 2020.

IVF treatment to restrict women to one embryo only each time

In order to avoid the dangers of multiple births, women having in vitro fertilisation may be limited to having just one embryo implanted at a time.

In vivo engineering of organs: The bone bioreactor

An international team of biomedical engineers has demonstrated for the first time that it is possible to grow healthy new bone reliably in one part of the body and use it to repair damaged bone at a different location.

Fertility drugs may be ineffective for women who lack a gene called the estrogen receptor beta

"What we found is that the beta estrogen receptor plays a role in moving the egg outside the ovary so it can be fertilized," said Kenneth Korach, Ph.D., Laboratory Chief at the National Institute of Environmental Health Sciences (NIEHS) where the research was conducted. "We never knew before what function this receptor played in reproduction."

Spontaneous contractions suppressed in late-term rat pregnancy

A long-time aim of obstetrical research has been to find agents that could delay or diminish pre-term labor because even today pre-term birth is a leading cause of infant mortality and morbidity.

FDA fast tracks HIV protease inhibitor from Vertex and GSK

Vertex Pharmaceuticals has announced that its collaborator, GlaxoSmithKline (GSK), has received fast track designation for the HIV protease inhibitor (PI) 640385 (VX-385) from the United States Food and Drug Administration.

Novel way in which the brain size of developing mammals may be regulated

Howard Hughes Medical Institute researchers have discovered a novel way in which the brain size of developing mammals may be regulated. They have identified a signaling pathway that controls the orientation in which dividing neural progenitor cells are cleaved during development.

Viagra's non-blood pressure effect successfully mimics vasopressin action

Normally your kidneys filter about 50 gallons of blood a day, remove such waste as salts and minerals, and concentrate it into urine. When you exercise or don't take in water, your blood "thickens" and instead of removing water, the kidney reverses the process, pulls in water from the body that would normally go into the urine, and puts it into the blood, thus maintaining water balance.

Uncomplicated twin pregnancies might be more risky than previously thought

As mothers get older and assisted conception becomes more common, the incidence of multiple births - primarily of nonidentical siblings, but also of identical ones - has dramatically increased.

Study causes big shift in how we think about p53 gene

The cellular cascade of molecular signals that instructs cells with fatally damaged DNA to self-destruct pivots on the p53 tumor suppressor gene. If p53 is inactivated, as it is in over half of all human cancers, checks and balances on cell growth fail to operate, and body cells start to accumulate mutations, which ultimately may lead to cancer.

High-tech infertility treatment for men most common therapy to help couples conceive

According to recently released figures, a high tech treatment for male infertility has become the most common therapy in Europe to help couples conceive.

Scientists identify inhibitors of the anthrax toxin

A collaborative team of scientists led by The Burnham Institute's Maurizio Pellecchia, Ph.D., has identified inhibitors of the anthrax toxin, termed lethal factor ("LF") that could be developed into an emergency treatment for exposure to inhalation anthrax.

Eggs from embryonic stem cells could benefit sterile women

Monash University researchers have developed a process that causes embryonic stem (ES) cells to develop into ovarian structures containing eggs.

New cardiovascular drug derived from Dan Shen (Saliva miltiorrhiza)

Through a large number of clinical trials over the past 3 years, researchers from the CAS Shanghai Institute of Materia Medica (SIMM) have developed a new cardiovascular drug with a definite effective component extracted from Dan Shen (Saliva miltiorrhiza), a medicinal herb widely used in China.

Researchers use novel cocktail of cells to coax muscle tissue to develop its own vascular network

For years, a major obstacle has dashed the hopes of creating "replacement parts" for the human body: the lack of an internal, nourishing blood system in engineered tissues. Without it, thicker tissues can't thrive, which has confined tissue engineering's practical application to thin skin, which can recruit blood vessels from underlying tissue.

Australian researchers develop process that causes embryonic stem cells to develop into ovarian structures containing eggs

The researchers believe the process could in future be used to develop eggs for sterile women that contain the women's own genetic material.

Stem cells grown in lab mirror normal developmental steps

Johns Hopkins scientists have developed a way to study the earliest steps of human blood development using human embryonic stem cells grown in a lab dish instead of the embryos themselves.
