Boosting the immune system, cutting off tumor oxygen supply, may be keys to patients living longer
When melanoma of the eye spreads to the liver, patients have few good options. Surgery is frequently impossible, and chemotherapy hasn’t proven effective. But now, by simultaneously revving up the immune system and choking off the tumor’s oxygen supply, oncologists at Jefferson Medical College and the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia may have found a
Latest findings indicate one- and two-year study results not as predictive as longer-term studies
In their efforts to explore more effective and efficient ways to conduct clinical trials, Mayo Clinic cancer researchers will present new recommendations about how long studies should track results when evaluating new cancer therapies. An analysis led by Daniel Sargent, Ph.D., director of statistics for Mayo Clinic Cancer Center, shows that many study results garnered after three years
Patients treated for early stage colon cancer fared significantly better if they exercised regularly at the level of an hour’s walk six times a week, according to a study to be presented at the annual meeting of the American Society of Clinical Oncology.
A person’s risk of having a cancer recurrence or dying was lowered by 40 to 50 percent in the 2 1/3 to 3 years following surgery and chemotherapy for stage III colon cancer, reported a team headed by Jeffrey Meyerhardt, MD, MPH, of Da
This year, more than 145,000 people will be diagnosed with colorectal cancer (CRC). Despite its high incidence, CRC is one of the most preventable and treatable forms of cancer when found early. Studies presented today at Digestive Disease Week® 2005 (DDW) explore three novel technologies for colorectal cancer screening that provide innovative techniques that could potentially overcome limitations of existing screening methods. “Colonoscopy is currently the gold standard for detection of colore
A new global wind power map has quantified global wind power and may help planners place turbines in locations that can maximize power from the winds and provide widely available low-cost energy. After analyzing more than 8,000 wind speed measurements in an effort to identify the world’s wind power potential for the first time, Cristina Archer and Mark Jacobson of Stanford University suggest that wind captured at specific locations, if even partially harnessed, can generate more than eno
Analysis of plate internal structure rules out thermoregulation
The bizarre plates and spikes that lined the backbones of the long-extinct stegosaurs were probably extreme examples of the often elaborate and colorful displays developed by animals to recognize fellow members of their species, according to an international team of paleontologists.
The team’s analysis of stegosaur plates lends support to a growing consensus among paleontologists that the weird adornments of
Engineers at The University of Texas at Austin have found a way to modify a plastic to anchor molecules that promote nerve regeneration, blood vessel growth or other biological processes.
In the study led by Dr. Christine Schmidt, the researchers identified a piece of protein from among a billion candidates that could perform the unusual feat of attaching to polypyrrole, a synthetic polymer (plastic) that conducts electricity and has shown promise in biomedical applications. When
Researchers have gathered evidence which shows that combined chronic exposure to noise and carbon monoxide in the workplace induces hearing loss. Adriana Lacerda, researcher at the École d’orthophonie et d’audiologie of the Université de Montréal, presents her findings at the annual meeting of the Acoustical Society of America in Vancouver on Wednesday. Those findings are the result of a study conducted with over 8,600 workers exposed to both noise and carbon monoxide in the workplace
With mobile phones attaining almost universal coverage in Europe, the focus has now shifted to providing the next generation of content-rich applications and services to end users.
The IST-funded project MAESTRO aims to play its part in this evolution by harnessing satellite technology together with existing 3G UMTS networks to deliver interactive digital multimedia services to mobile users.
Launched in January 2004, MAESTRO sets out to use Satellite Digital Multimedia B
A Buckinghamshire company whose intelligent robots can assist surgeons during complex operations has raised £1.025 million with the help of Oxfordshire Investment Opportunity Network (OION), Europe’s leading technology business angel network, and investment from Hoegh Capital and Octopus Asset Management. Armstrong Healthcare Ltd, a world-leading producer of image-guided surgical robots, will use the funds to support the development of its three main products through clinical trials to launc
The mammoth B-15A iceberg appears poised to strike another floating Antarctic ice feature, a month on from a passing blow that broke off the end of the Drygalski ice tongue. As this Envisat image reveals, this time its target is the ice tongue of the Aviator Glacier.
First discovered in 1955, and named to mark the work done by airmen to open up the Antarctic continent, the Aviator Glacier is a major valley glacier descending from the plateau of Victoria Land along the west side
Over £1/2 million has been raised by The Prostate Project, a Surrey based charity, to create a new centre for prostate cancer research in Guildford. The Prostate Project, the University of Surrey and the Royal Surrey County Hospital have today signed an agreement where The Prostate Project will donate £550,000 to establish a Chair of Urological Oncology. The post, and its supporting research team, will be based at the Postgraduate Medical School at the University of Surrey, which is also providing
The Cancer Department at the la University of Navarra University Hospital has acquired a Siemens, latest-generation lineal accelerator. This is the first centre in Spain to install this advanced radiotherapy apparatus which is equipped with multilaminas, minimultilaminas and portal vision.
The new radiotherapy equipment has the Moduleaf system as an extra feature minilaminas of 2.5 mm – the thinnest that currently exists in this technology – that can shape irregular parts of tumo
Researchers delving into today’s complicated range of family set-ups must recognise that ‘brother and sister’ relationships are now about far more than blood ties and living in the same home, warns a new study sponsored by the ESRC.
As 21st Century children and young people create their own, complex understandings of who and what is a sibling, the important social implications need to be taken on board, says a working paper from a team led by Professor Rosalind Edwards of th
Those considered high-risk for melanoma – the most dangerous form of skin cancer – are no more likely to sunbathe protected than those who are unaware of their risk, according to a new study conducted by MUHC researchers. The study, published in the Journal of Cutaneous Medicine and Surgery, examined the behaviour of melanoma patients in order to assess the efficacy of sun-awareness and protection campaigns. “Patients with a personal or family history of melanoma, or that burn eas
The drug DFMO prevents cancer in laboratory models of lymphoma but fails to kill existing cancerous cells that have lost the ability to self-destruct, according to investigators at St. Jude
Drugs that block the enzyme Odc prevent the onset of cancers that would otherwise be triggered by a family of cancer-causing genes called Myc, according to investigators at St. Jude Children’s Research Hospital. The researchers showed that disabling Odc disrupts the ability of Myc genes to
