It is estimated that 38 million people worldwide are currently infected with HIV and that 4.1 million more are added each year. For scientists to design treatment therapies that are effective over the long-term it is essential to learn more about how the virus mutates and develops resistance to medications.

New, groundbreaking research by University of Victoria biomedical engineer Stephanie Willerth has significantly advanced the understanding of HIV and how to treat it.

SAN ANTONIO — The presence of one to four circulating tumor cells (CTCs) in the blood of early-stage breast cancer patients almost doubled patient's risk of cancer relapse and death, and five or more CTCs increased recurrence by 400 percent and death by 300 percent, according to Phase III results of the SUCCESS trial. These cells were found in patients after surgery but before chemotherapy treatment.

SAN ANTONIO — A high level of circulating tumor cells (CTCs) — cells that have detached from a tumor and are circulating in the body through the blood — are an independent prognostic marker in metastatic breast cancer as first-line therapy. In addition, persistence of high CTC level during therapy was found to be an early marker of poor outcome.

SAN ANTONIO — For patients with breast cancer and bone metastases, denosumab delayed skeletal-related side effects five months longer compared to those on zoledronic acid, according to results presented at the 33rd Annual CTRC-AACR San Antonio Breast Cancer Symposium, held Dec. 8-12.

SAN ANTONIO — Metastatic breast cancer patients who had circulating tumor cells (CTCs) in their blood before or after high-dose chemotherapy (HDCT) followed by autologous stem cell transplantation had poor outcomes, according to researchers from the University of Texas MD Anderson Cancer Center.

San Antonio - Metastatic breast cancer patients whose blood contains circulating tumor cells (CTCs) before or after treatment with high-dose chemotherapy and blood stem cell transplant have shorter survival periods, according to a new study by researchers at The University of Texas MD Anderson Cancer Center in Houston.

The findings were presented today in a poster session at the 33rd Annual CTRC-AACR San Antonio Breast Cancer Symposium.

Scientists have discovered how a network of repair proteins enables bacteria to prioritise the repair of the most heavily used regions of the DNA molecules that carry the instructions necessary for living cells to function.

The research, carried out by academics at the University of Bristol and published in Molecular Cell (Dec. 2010), reveals that there are greater similarities between the DNA repair systems of bacteria and humans than had been suspected.

A gene target for drug resistance, a triple-drug cocktail for triple negative breast cancer, and patients' risk for carpal tunnel syndrome are among study highlights scheduled to be presented by Johns Hopkins Kimmel Cancer Center scientists during the 33rd Annual CTRC-AACR San Antonio Breast Cancer Symposium, held Dec. 8-12. The information is embargoed for the time of presentation at the symposium.

TRIO OF DRUGS MAY COMBAT "TRIPLE NEGATIVE" BREAST CANCER(Presentation # PD01-05)

SIMPLE FINGERTIP TEST MAY IDENTIFY BREAST CANCER PATIENTS AT RISK FOR CARPAL TUNNEL SYNDROME(Presentation # P2-14-09)

Children with ADHD can sometimes have more difficulties on math and reading tests compared to their peers. A new study published in Psychological Science, a journal of the Association for Psychological Science, used identical and fraternal twins to look at the genetic and environmental influences underlying ADHD behaviors, reading, and math skills in children in an attempt to better understand the relationship among them.

Up to 20% of professional boxers develop neuropsychiatric sequelae. But which acute complications and which late sequelae can boxers expect throughout the course of their career? These are the questions studied by Hans Förstl from the Technical University Munich and his co-authors in the current issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2010; 107[47]: 835-9).

Despite threats of violence, imprisonment and death, writers around the world continue to fight to make their voices heard. The latest issue of Index on Censorship pays tribute to one of the world's longest running campaigns for free expression, English PEN's Writers in Prison Committee (WiPC). Founded in 1960, the WiPC supports and protects writers facing persecution around the globe. Contributors to Beyond Bars – including award-winning authors Margaret Atwood, Sir Tom Stoppard and William Boyd – highlight the vital role writers can play in supporting their colleagues.

LEBANON, NH - Kathy Niedzwiecki of Pelham, NH, and Ken Crowder of St. Louis are experiencing renewed life and health thanks to the generosity of two living kidney donors.

The strain of cholera currently sweeping through post-earthquake Haiti originated in South Asia, conclude scientists who did a rapid genetic analysis of bacteria collected from Haitian patients. The finding supports the notion that the cholera bacteria fueling the outbreak arrived on the island via recent visitors.
