Tissue Regeneration Therapeutics Inc. will exclusively license its human umbilical cord perivascular cell (HUCPVC) technology to Stem Cell Authority Ltd. for family stem cell banking in the U.S.

The technology originated at the University of Toronto and has been offered to the public in Canada since March 2007 through a licensing agreement between TRT and Toronto-based CReAte Cord Blood Bank (CCBB).

A team of researchers, led by surgeons at the Kimmel Cancer Center at Jefferson in Philadelphia, has found further evidence supporting the ability of a protein to predict how well a patient with advanced pancreatic cancer will do after surgery, chemotherapy and radiation. The levels of the protein CA 19-9 in the blood can be used to determine the need for further therapy, they say.

Haptics means “of or relating to the sense of touch”. Haptics Technolofy refers to the technology that connects the user to a computerized system via the sense of touch by applying forces, vibrations and/or motions to the user.

A diet rich in omega-3 polyunsaturated fatty acids found in certain fish or fish oil, nuts, seeds, and vegetable oils may help lower prostate cancer risk in individuals with a genetic predisposition to cancer.

While many genetic mutations are known to predispose to cancer, it has remained unclear whether dietary fat can modulate the risk of developing cancer in genetically predisposed individuals. Some studies suggest that a diet rich in omega-3 polyunsaturated fatty acids reduces cancer incidence.

Bacteria called Dehalococcoides Ethenogenes, discovered in Ithaca sewage sludge in 1997 by James Gossett, Cornell professor of civil and environmental engineering, are now in wide use to detoxify some carcinogenic chemicals but they could be used for a lot more.

These bacteria remove chlorine atoms from molecules and leave less-toxic compounds behind in toxic waste like perchloroethylene (PCE) and trichloroethylene (TCE).

Human resistance to a retrovirus that infected chimpanzees and other nonhuman primates 4 million years ago ironically may be at least partially responsible for the susceptibility of humans to HIV infection today.

These findings, reported by a team of researchers at Fred Hutchinson Cancer Research Center in the June 22 issue of Science, provide a better understanding of this modern pandemic infection through the study of an ancient virus called Pan troglodytes endogenous retrovirus, or PtERV1.

Using mathematical theory, UC Irvine scientists have shed light on one of cancer’s most troubling puzzles -- how cancer cells can alter their own genetic makeup to accelerate tumor growth. The discovery shows for the first time why this change occurs, providing insight into how cancerous tumors thrive and a potential foundation for future cancer treatments.

The extinction of many large mammals at the end of the Ice Age may have packed an even bigger punch than scientists have realized. To the list of victims such as woolly mammoths and saber-toothed cats, a Smithsonian-led team of scientists has added one more: a highly carnivorous form of wolf that lived in Alaska, north of the ice sheets.

Wolves were generally thought to have survived the end-Pleistocene extinction relatively unscathed. But this previously unrecognized type of wolf appears to have vanished without a trace some 12,000 years ago.

In the first trial of its kind in the world, 60 patients who have recently suffered a major heart attack will be injected with selected stem cells from their own bone marrow during routine coronary bypass surgery.

The Bristol trial will test whether the stem cells will repair heart muscle cells damaged by the heart attack, by preventing late scar formation and hence impaired heart contraction.

Researchers at Sandia National Laboratories in California have emerged as key players in a state-of-the-art program for the U.S. Army that focuses on the design and manufacturing of a lightweight, high-caliber, self-propelled cannon system.

The weapon system, known as the Non-Line-of-Sight Cannon (NLOS Cannon) is fully automated and can fire at a sustained rate of six rounds per minute. The vehicle, once completed, must be light and agile enough to fit three vehicles comfortably onto a C-17 cargo aircraft.

It may not seem so at the time, but women who suffer through morning sickness during their pregnancies actually may be fortunate.

Those women may have a 30 percent lower risk of developing breast cancer later in life than mothers-to-be who experience nine nausea-free months, a new study by epidemiologists at the University at Buffalo suggests.

The genes that make up the immune system of the Aedes aegypti mosquito which transmits deadly viral diseases to humans have been identified in new research out today in Science.

The immune system of this mosquito is of great importance as scientists believe it plays a key role in controlling the transmission of viruses that cause yellow and dengue fevers – diseases that infect over 50 million people worldwide every year.

University of Nottingham scientists have been instrumental in helping to establish a pioneering branch of chemistry in Ethiopia.

They have helped to introduce Green Chemistry, an emerging field of sustainable science that will help African nations to meet the challenges of the 21st century.

Green Chemistry focuses on greener ways of creating chemicals, and is now regarded as one of the major routes to more environmentally-friendly production of the chemicals that underpin modern society.

David H. Ingbar MD, president of the American Thoracic Society, today called the proposed standards issued by the Environmental Protection Agency for ozone pollution–commonly known as smog-“unhealthy for America’s kids, unhealthy for America’s seniors, and unhealthy for America.”

“The science is clear,” Dr. Ingbar said, “ozone pollution is causing unnecessary, illnesses and death in America. The proposed EPA standards fall short of providing the protection needed to keep Americans safe from ozone air pollution.”

Drinking your coffee black or decaffeinated to keep cholesterol in check? Think again.

Cafestol, a compound found in coffee, elevates cholesterol by hijacking a receptor in an intestinal pathway critical to its regulation, said researchers from Baylor College of Medicine in a report that appears in the July issue of the journal Molecular Endocrinology.
