The idea that rigidity and orderliness go together is a triumph of modern theoretical physics.

Wake Forest study shows women suffer from 'gender gap' in treatment of severe psoriasis
When it comes to the treatment of severe psoriasis, there is no equality between the sexes.

Cell pathways' SAANDs compounds enhance antitumor effects of Taxol™ in rodent models of breast cancer
Subtherapeutic doses of Cell Pathways' CP461, a selective apoptotic antineoplastic drug (SAAND) compound, demonstrated the ability to significantly enhance the anti-tumor activity of Taxol™ (paclitaxel) without further toxic side-effects in a classic mouse model of human breast cancer.

New study may widen options in breast cancer treatment
New data presented at the 91st Annual Meeting of the American Association for Cancer Research (AACR) strengthen the evidence for the use of two biomarkers to predict relapse, which may help certain women avoid the rigors of adjuvant chemotherapy.

Reduction in pediatric infectious diseases anticipated as new pneumococcal vaccine enters the market
The Food and Drug Administration's recent approval of Prevnar, a new vaccine developed specifically for infants and toddlers, is expected to have a significant impact in the number of cases of pneumococcal infections - illnesses that can have devastating effects - according to Deborah Lehman, M.D., a specialist in pediatric infectious diseases at Cedars-Sinai Medical Center.

Educating Asian Americans about services could speed care
Improving education about available mental health services for Asian Americans can break down cultural barriers that may contribute to delayed treatment for serious disorders such as schizophrenia and manic depression, a University of Illinois researcher says.

National Jewish, EPA put HEPA filters, air purifiers to the test
HEPA-filter equipped vacuums and air filtration systems are used in many homes on the assumption that the devices lower allergic symptoms by removing allergens and irritants from the floor and air, respectively.

OHSU Researchers awarded NIH grant to study end-of-life issues in Oregon
Oregon Health Sciences University researchers have receieved a grant from the NIH to study why Oregon has the lowest in- hospital death rate in the country.

Aptosyn™ (exisulind) and other SAANDs target early event in cancer; AACR presentations detail novel apoptotic pathway
A new family of potential anticancer agents selectively trigger apoptosis in precancerous and cancerous cells without harming normal cells.

The Johan Skytte Prize to Professor Fritz W. Scharpf
The Johan Skytte Foundation at Uppsala University, Sweden, has awarded Professor Fritz W.

Exisulind (Aptosyn™) and other SAANDs compounds halt prostate cancer cell growth by two mechanisms
Columbia University and Cell Pathways scientists report exisulind and related compounds inhibit prostate cancer both by inducing apoptosis and by making the cancerous cells less responsive to growth-promoting androgens.

New vaccine technique offers hope for asthma and allergy sufferers
Efforts to develop improved vaccines for asthma and allergies have been thwarted because the vaccines themselves often cause the very symptoms a person is trying to avoid.

Targeted Genetics presents advances in systemic gene delivery technology
Targeted Genetics presents data on the company's synthetic gene delivery platform at the AACR meeting indicating that the LPD LPD (Lipid Polycation DNA)gene delivery system is capable of delivering genes systemically when delivered intravenously.

Mathematical model could remedy costly steel-making problem
In the modern making of steel, molten metal flows from a bathtub-shaped vessel called a tundish into a water-cooled, bottomless mold in a continuous casting operation.

Unique study reveals new details on how genes are transcribed
Scientists at Berkeley have reported the first direct observations of what happens when the message of a gene is being read during the actual transcription of single DNA molecules.

MIT students develop mini satellites
Picture the Air Force's Thunderbirds flying in formation in an air show.

Government and business are missing the green wave
Research published today shows that British industry and the Government are not taking full advantage of science and technology in innovating to protect the environment.

Team finds cell gene that helps viruses multiply
Working with a virus introduced into a yeast, scientists have found a cellular gene that is commandeered by the virus to help it multiply.

Patients with severe emphysema enrolled in major, nationwide study conducted at Cedars-Sinai Medical Center
Patients with severe emphysema are being enrolled at Cedars- Sinai Medical Center (Los Angeles) and at 16 other sites nationwide, in a major study comparing the outcomes of emphysema patients who receive maximum medical therapy with those who undergo medical therapy in combination with lung volume reduction surgery.
