Children with low-risk retinoblastoma do not need postoperative chemotherapy

New results from a prospective clinical trial conducted in France show that children with low-risk retinoblastoma do not need postoperative (adjuvant) chemotherapy to prevent disease recurrence or metastasis; the results also suggest that certain patients with intermediate-risk disease can receive less aggressive adjuvant treatment, or perhaps forego it altogether. Avoiding chemotherapy spares patients from treatment side effects and long-term health risks, such as cardiovascular disease and development of a second cancer.

Breast cancer tests: an interview with Dr Steven Quay, CEO of Atossa Genetics

Breast cancer is a major concern throughout the world. It is the number 1 cancer among women and in the Western world it generates approximately one new case per minute: 24 hours a day 7 days a week.

New test for leprosy gives results in less than 10 minutes, New York Times reports

"A simple, fast and inexpensive new test for leprosy offers hope that, even in the poorest countries, victims can be found and cured before they become permanently disabled or disfigured like the shunned lepers of yore," the New York Times reports.

Plasma plays a crucial part in determining how blood flows

Blood flows differently than water. Anyone who has ever cut themselves knows that blood flows viscously and rather erratically. The similarity between blood and ketchup is something not only filmmakers are aware of. Experts refer to these materials as "non-Newtonian fluids," of which ketchup and blood are prime examples.

Study shows how gene mutations affect calcium pathway in arrhythmia

Using powerful X-rays, University of British Columbia researchers have reconstructed a crime scene too small for any microscope to observe - and caught the culprit of arrhythmia in action.

Central College to study effects of triclosan on heart rate

How often does a heart beat? For a zebrafish, it depends on the water it's swimming in. Ellen Du Pre, professor of biology at Central College, is working with four students, as well as biology colleague Nicole Palenske, to study the effects of triclosan on heart rate. The tiny fish, which can be as small as an eyelash when newly hatched, is transparent, and the students can easily count the heart beats under a microscope.

New insights into how cells stick to each other and to other bodily structures

Research carried out by scientists at the Georgia Institute of Technology and The University of Manchester has revealed new insights into how cells stick to each other and to other bodily structures, an essential function in the formation of tissue structures and organs. It's thought that abnormalities in their ability to do so play an important role in a broad range of disorders, including cardiovascular disease and cancer.

Patient-specific cancer cell lines designed to predict chemotherapy sensitivity

In laboratory studies, scientists at the Johns Hopkins Kimmel Cancer Center have developed a way to personalize chemotherapy drug selection for cancer patients by using cell lines created from their own tumors.

Improving tuberculosis (TB) diagnosis: an interview with Professor Madhukar Pai, MD, PhD

TB is an infectious disease caused by Mycobacterium tuberculosis. Nearly 9 million people develop TB every year, and TB kills nearly 1.4 million individuals each year. While the incidence of TB has steadily declined in the west, it remains a huge public health problem in many developing countries, with India having the highest burden.

Exercise may reduce risk of prostate cancer in Caucasian men

A new study suggests that exercise may reduce Caucasian men's risk of developing prostate cancer. And among Caucasian men who do have prostate cancer, exercise may reduce their risk of having more serious forms of the disease. Unfortunately, the benefits do not seem to apply to African- American men. The study is published early online in CANCER, a peer-reviewed journal of the American Cancer Society.

New method can determine seriousness of cancer prognosis with 80% certainty

The number of incorrect cancer prognoses can be halved with computerised image analysis. In three years time, the method can be used on patients with bowel cancer, ovarian cancer and prostate cancer.

Viewpoints: Obama's 'olive branch' on birth control coverage; Sen. Kirk recounts his stroke therapy; Nurses oppose mandatory flu shots

The Obama administration released the final details Friday of the exemption it will provide religious-affiliated employers from the requirement to include free birth control in employees' insurance policies. Not surprisingly, the announcement didn't seem to mollify any of the critics who'd been arguing that the exemption was inadequate.

Study shows how placental circulation can influence malarial parasite behavior and infection

Malaria in pregnancy causes a range of adverse effects, including abortions, stillbirths, premature delivery and low infant birth weight. Many of these effects are thought to derive from a placental inflammatory response resulting from interaction of infected red blood cells with the placental tissue.

Researchers determine differences in stiffness between healthy and cancerous tissue

The texture of breast cancer tissue differs from that of healthy tissue. Using a cutting-edge tissue diagnostic device, a group of researchers in Basel, Switzerland, has determined one key difference: cancerous tissue is a mix of stiff and soft zones, whereas healthy tissue has uniform stiffness.
