Chromosomes in the nucleus of the cell carry the material of heredity, or genes

Abnormal cell division that yields cells with an extra set of chromosomes can initiate the development of tumors in mice, researchers at Dana-Farber Cancer Institute have shown, validating a controversial theory about cancer causation put forth by a scientific visionary nearly 100 years ago.

New fungal defensin, plectasin, possesses as much power as penicillin

A peptide identified in a fungus found in northern European pine forests possesses as much power as penicillin as well as vancomycin, according to an international team of researchers.

Microfluidics can be used successfully for IVF in mice

Technology that more closely mirrors the natural fertilization process is showing promise as a new method of in-vitro fertilization, researchers at the University of Michigan Health System have found.

Quest to develop synthetic versions of rare natural substances to cure tobacco-related diseases

Within a laboratory on the Florida State University campus, a chemist leads a team of researchers in a quest to develop synthetic versions of rare natural substances. If all goes well, the team’s efforts could pay off in the form of the next generation of cancer-fighting drugs.

Lowering infant's body temperature within the first six hours of life reduces the chances for disability

Lowering an infant's body temperature to about 92 degrees Fahrenheit within the first six hours of life reduces the chances for disability and death among infants who failed to receive enough oxygen or blood to the brain during birth. The research study findings appear in tomorrow's 2005 New England Journal of Medicine.

Obesity associated with a threefold increase in SCD1 expression in obese muscle

The gene encoding an enzyme that hinders muscle from burning fat manufactures three times more enzyme in the muscle of obese people than lean people, researchers from Duke University Medical Center and Louisiana State University have found. This causes the obese muscle tissue to both store more fat and burn less fat, the researchers said.

New monoclonal antibody that targets immune system B cells shows promise for treating leukemias

In studies with mice, treatment with a new monoclonal antibody that targets immune system B cells has shown considerable promise for treating leukemias, autoimmune diseases and transplant rejection, according to immunologists at Duke University Medical Center.

Natural cancer killing cells from the human embryonic stem cells

For the first time, stem cell researchers at the University of Minnesota have coaxed human embryonic stem cells to create cancer-killing cells in the laboratory, paving the way for future treatments for various types of cancers (or tumors).

Bats carry SARS like virus

An international consortium headed by CAS researchers has identified that the Chinese horseshoe bat is healthy carriers of a virus that is very closely related to those causing SARS (severe acute respiratory syndrome).

Potential new treatment for stroke

"The study was designed to test if IL-1ra is safe in stroke patients and showed promising results," said Professor Rothwell, a world-renowned neuroscientist based in the University's Faculty of Life Sciences.

New way to measure the impact of AIDS on the living brain

A new University of California - Los Angeles/University of Pittsburgh imaging study for the first time shows the selective pattern of destruction inflicted by AIDS on brain regions that control motor, language and sensory functions. High-resolution 3-D color scans created from magnetic resonance images (MRI) vividly illustrate the damage.

Real dangers from environmental toxins most likely occur early in life

Exposure of developing fetuses and newborns to low levels of environmental toxins such as lead, mercury and dioxin, as well as nicotine and ethanol, could be behind the recent sharp rises in asthma, allergies and autoimmune disorders like lupus, says a Cornell University researcher.

Researchers find gene that is important for the control of fundamental rhythms in nematode worms

University of Utah biologists found a gene that controls rhythmic events in a worm's life: swallowing food, laying eggs and pooping.

Discovery of new features of a key quality-control mechanism in our cells

Mutations in genes are the basis of evolution, so we owe our existence to them. Most mutations are harmful, however, because they cause cells to build defective proteins. So cells have evolved quality control mechanisms that recognize and counteract genetic mistakes.

20 percent of people with chronic hepatitis C who receive a liver transplant will develop advanced cirrhosis

A new study from the University of North Carolina at Chapel Hill School of Medicine may have found a way to identify those at greatest risk, thereby allowing doctors to decide who should receive treatment that could save the transplanted organ. The new findings appear in the October issue of the journal Liver Transplantation.

Specific gene on chromosome 15 regulates inflammation

A team of international researchers has discovered that a specific gene on chromosome 15 regulates inflammation, a finding with implications for a wide range of disorders, including cancer, cardiovascular disease, diabetes, obesity, Alzheimer's, and infections. The findings are published in the October 9 online issue of Nature Genetics.

Avian influenza and the U.S

If a virulent strain of avian influenza ever struck the U.S. poultry industry, this country probably would fare better than many other nations due to careful biosecurity procedures in force.

Cells inside the hair follicle are true multipotent stem cells

Using an animal model, a research team led by Yann Barrandon at the EPFL (Ecole Polytechnique Federale de Lausanne) and the CHUV (Lausanne University Hospital) has discovered that certain cells inside the hair follicle are true multipotent stem cells, capable of developing into the many different cell types needed for hair growth and follicle replacement.

The cocktail party problem

Known as "the cocktail party problem," the ability of the brain's auditory processing centers to sort a babble of different sounds, like cocktail party chatter, into identifiable individual voices has long been a mystery.

GRK5 protein plays important role in hypertension

Researchers at Jefferson Medical College have implicated a protein called GRK5 as having an important role behind essential hypertension, which affects more than 65 million Americans.
