Mathematicians Predict Patterns in Fingerprints

Patterns in nature can be seen every day, yet in many cases, little is understood about how and why they form. Now University of Arizona mathematicians have found a way to predict natural patterns, including fingerprints and the spirals seen in cacti.

New software promises to speed drug development

Researchers at Rensselaer Polytechnic Institute today announced the release of a software program capable of quickly identifying molecules that show promise for future medicines. The software program enables drug makers to comb through enormous databases of potential molecules and identify the ones that have sound medicinal properties.

New center enables genetic treatments and advances

A new state-of-the-art research facility dedicated to helping produce modified cells for treatment of cancer and other diseases recently opened at the Siteman Cancer Center.

Compounds that may stop replication of T-cell leukemia virus

Researchers are analyzing several compounds that may inhibit the enzyme that is essential for the reproduction of the Human T-cell Leukemia Virus Type 1 (HTLV-I), which has infected 15 to 20 million people worldwide. The virus causes the fatal adult T-cell leukemia in up to 10 percent of those infected.

Lab discovers way to keep short-lived catalysts active for longer than five months

Enzymes, the workhorses of chemical reactions in cells, lead short and brutal lives. They cleave and assemble proteins and metabolize compounds for a few hours, and then they are spent. This sad fact of nature has limited the possibilities of harnessing enzymes as catalytic tools outside the cell, in uses that range from biosensing to toxic waste cleanup.

Scientists have discovered that a non-genetic molecular process can effect cell behaviour

Genetic mutations, sudden, random and usually harmful changes to the structure of a gene, are only one factor that determines the ultimate fate of a cell. Chicago scientists have discovered that a non-genetic molecular process also can play a role, and that experimenters can influence this process in bacteria, they report in the April 1 issue of the journal Nature.

T-cells in lupus patients avoid apoptosis and are stimulated to produce antibodies against the patients own DNA

Researchers studying autoimmune diseases have found a molecular mechanism that explains how T-cells in lupus patients avoid apoptosis and are stimulated to produce antibodies against the patients own DNA.

Gene-rich human Chromosome 19 sequence completed

The United States Department of Energy (DOE) Joint Genome Institute (JGI) and Stanford University report today the completion of the sequencing of human chromosome 19, the most gene-rich of all the human chromosomes.

Scientists seek cause for what makes good cell go bad

Genetic mutations--sudden, random and usually harmful changes to the structure of a gene--are only one factor that determines the ultimate fate of a cell. Chicago scientists have discovered that a non-genetic molecular process also can play a role, and that experimenters can influence this process in bacteria, they report in the April 1 issue of the journal Nature.

Research team has found a new way to streamline gene isolation to determine their functions

A single strand of plant or animal DNA may contain tens of thousands of genes, each programmed to produce a specific protein essential for the growth or survival of the organism. The challenge for geneticists is to isolate individual genes and determine their function -- a painstaking process often requiring years of laboratory trial and error.

Drug, Nembutal can suppress activity in colon cancer cells

A barbiturate once commonly used to treat anxiety may play a role in controlling the spread of colon cancer, say researchers from The University of Texas M. D. Anderson Cancer Center.

Discovery of gender difference in cartilage cells may help spinal disc repair

When biologist Barbara Boyan discovered science’s first proof of biochemical differences between male and female cartilage cells, she began to question the approaches she and other researchers were taking to study cells. Was their thinking biologically relevant?

Faster new cloning technique - transcript-based cloning

A single strand of plant or animal DNA may contain tens of thousands of genes, each programmed to produce a specific protein essential for the growth or survival of the organism. The challenge for geneticists is to isolate individual genes and determine their function – a painstaking process often requiring years of laboratory trial and error.

Embryonic stem cells attached to a gel matrix instead of suspended in solution

Like many other kinds of cells used in biomedical research, human embryonic stem cells are stored and transported in a cryopreserved state, frozen to -320 degrees Fahrenheit, the temperature of their liquid nitrogen storage bath.

Natural compound in snake venom for treatment of malignant tumours

Researchers at the University of South Australia have made a major discovery using a natural compound in snake venom that shows very promising anti-cancer effects. The compound works by activating the destruction of cells which make up the blood vessels that supply nutrients to tumours, according to Associate Professor Tony Woods from UniSA’s School of Pharmaceutical, Molecular and Biomedical Sciences.

Removal of thyroid glands may be unnecessary for most patients

An unpleasant postoperative procedure for thyroid cancer patients who have had their thyroid glands surgically removed may be unnecessary for most patients, according to Washington University researchers at Siteman Cancer Center and Barnes-Jewish Hospital in St. Louis.

Zebrafish show effects of ionizing and UV radiation differ during embryo development

Adam Dicker, M.D., Ph.D., associate professor of radiation oncology at Jefferson Medical College of Thomas Jefferson University and Jefferson’s Kimmel Cancer Center in Philadelphia, Mary Frances McAleer, M.D., Ph.D., a resident in the Department of Radiation Oncology at Jefferson Medical College and their co-workers compared the effects on zebrafish embryos of two types of radiation – ionizing radiation, which is the kind given to patients for cancer treatment, and ultraviolet (UV) radiation, which comes naturally from the sun.

Discovery of novel gene profile that may identify colon stem cells

Researchers at Jefferson Medical College have uncovered a novel pattern of gene expression in the stem cell-rich bottom of tiny “crypts” in the tissue lining the colon. By identifying these patterns, the scientists hope to be able to identify mechanisms through which stem cells contribute to the development of colon cancer.

Extraction of RNA from Archived Formalin-Fixed, Paraffin-Embedded Tissue

For the first time, Fox Chase Cancer Center researchers have demonstrated the ability to extract RNA from formalin-fixed, paraffin-embedded tissue samples archived for up to five years. What's more, the technology used retrieves high-quality samples, allowing researchers to identify cancer-related genetic changes. Accepted as a "late-breaking" abstract, the research was presented today at the 95th Annual Meeting of the American Association for Cancer Research by Renata Coudry, M.D., a research pathologist at Fox Chase Cancer Center.

Novel uses for bacterial cellulose, artificial blood vessels, bioengineered wound dressing

New and unique products created from bacterial cellulose — from electronic paper to treatment for wounds — will highlight a one-day symposium at the 227th national meeting of the American Chemical Society, the world's largest scientific society.
