Prostate cancer patients who receive brachytherapy and remain free of disease for five years or greater are unlikely to have a recurrence at 10 years, according to a study in the July 1 issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Radiation Oncology (ASTRO).
Brachytherapy is the placement of radioactive sources in or just next to a tumor either permanently or temporarily, depending upon the cancer.

New research describes a molecular tool that shows great promise as a therapeutic for human acute myeloid leukemia (AML), a notoriously treatment-resistant blood cancer. The study, published by Cell Press in the July 2nd issue of the journal Cell Stem Cell, describes exciting preclinical studies in which a new therapeutic approach selectively attacks human cancer cells grown in the lab and in animal models of leukemia.
NEW YORK, JULY 2, 2009 – A new study by researchers at Memorial Sloan-Kettering Cancer Center (MSKCC) reveals the genetic underpinnings of what causes lung cancer to quickly metastasize, or spread, to the brain and the bone – the two most prominent sites of lung cancer relapse. The study will be published online in the journal Cell on July 2.
UCLA researchers have found that embryonic stem cells and skin cells reprogrammed into embryonic-like cells have inherent molecular differences, demonstrating for the first time that the two cell types are clearly distinguishable from one another.
More than 40 scientists, bioethicists, lawyers and science journal editors are calling on their colleagues, policy makers and the public to begin developing guidelines for the research and reproductive use of stem cell-derived eggs and sperm, even though such use may be a decade or more away.
BEER-SHEVA, ISRAEL, July 2, 2009 – Researchers at Ben-Gurion University of the Negev (BGU) have discovered that gene mutations that once helped humans survive may increase the possibility for diseases, including cancer.
The findings were recently the cover story in the journal Genome Research.
OKLAHOMA CITY – Researchers at the University of Oklahoma Health Sciences Center have found a way to use a natural compound to stop one of the leading causes of blindness in the United States. The research appears online this month in the journal Diabetes, a publication of the American Diabetes Association.
Hurricane Katrina was the largest natural disaster in U.S. history, claiming the lives of more than 1,800 victims and causing well over $100 billion in damage along the Gulf Coast. The 2005 storm breached every levee in New Orleans, flooding almost the entire city as well as the neighboring parishes. Yet a surprising number of people stayed behind and rode out the storm.
In times of doubt and uncertainty, many Americans turn to self-help books in search of encouragement, guidance and self-affirmation. The positive self-statements suggested in these books, such as "I am a lovable person" or "I will succeed," are designed to lift a person's low self-esteem and push them into positive action. According to a recent study in Psychological Science, a journal of the Association for Psychological Science, however, these statements can actually have the opposite effect.
Panel physicians are increasingly offering individual health services (IHS) to patients with statutory health insurance. This is documented by Susanne Richter et al. of the Department of Social Medicine, Lübeck University, in the new edition of Deutsches Ärzteblatt (Dtsch Arztebl Int 2009; 106(26): 433-9). IHS include medical health services which are not reimbursed by the health insurance funds and which the patient has to pay for himself.
DURHAM, N.C. -- As flowering plants like giant trees quickly rose to dominate plant communities during the Cretaceous period, the ferns that had preceded them hardly saw it as a disappointment.
In fact, they flourished. While modern tropical rain forests were becoming established, ferns climbed aboard, and experienced a flowering of their own species diversity.
"The canopy is there and -- boom -- diversification," said Duke University researcher Eric Schuettpelz, who is completing a post-doctoral fellowship in biology with associate professor Kathleen Pryer.
The Archaea are single-celled organisms and a domain unto themselves, quite apart from the so called eukaryotes, being bacteria and higher organisms. Many species live under extreme conditions, and carry out unique biochemical processes shared neither with bacteria nor with eukaryotes. Methanogenic archaeans, for example, can produce methane gas out of carbon dioxide and hydrogen. The underlying chemical reaction, a reduction, involves the cofactor known as F0 or F420 which is the tiny molecule deazaflavin.
London, 2 July 2009 – The partners of Research4Life announced today at the World Conference of Science Journalists 2009 that a new research impact analysis has demonstrated a dramatic rise in research output by scientists in the developing world since 2002. By comparing absolute growth in published research before (1996 – 2002) and after (2002 - 2008) the advent of the Research4Life programmes, the analysis has revealed a 194% or 6.4-fold increase in articles published in peer reviewed journals.
