New Delhi, Dec 5 : To create more awareness about breast cancer, Fortis La Femme will be organising ‘Motarde’ — a women-s only bike rally here on December 4.

Nows-a-days breast cancer is most common cancer in most cities in India and Fortis La Femme had run a two-month-long special campaign across Delhi and Bengaluru wherein women were encouraged to learn about breast self-examination and go for mammography and breast checks by a clinician.

Fortis La Femme is leading the way towards boosting awareness of this disease and is happy to extend support, services and advice to mark Breast Cancer Awareness Month. We see this as crucial to our single-minded campaign for women’s health and wellness,” said Anika Parashar, COO, Fortis La Femme in a statement.

New blood test may help early detection of 8 cancers

Blood Test Cancer

Sydney, Jan 19: A new blood test that can help in the early diagnoses of eight common cancers before they spread and risk patients’ chances of survival has been developed by Australian researchers.

The new test would help early detection of cancers affecting the ovary, liver, stomach, pancreas, oesophagus, bowel, lung and breast, Xinhua quotes a statement from the Walter and Eliza Hall Institute of Medical Research in Australia.

The test “has the potential to be a one-stop, safe screening test for multiple tumour types that should have high community acceptance,” Jeanne Tie, Associate Professor at the institute was quoted as saying.

“For the first time, we have the promise of a screening test that will lead to earlier diagnosis and improved survival outcomes for many tumor types that are major contributors to cancer deaths in our community,” Tie added.

Cancer survival rates are directly linked to how advanced the disease is in a patient during diagnosis, which means that blood tests that can accurately detect the illness well before the symptoms are present is urgently needed.

There are still no effective screening tests for many major tumor types and available tests can each only screen for one cancer at a time, the report said.

The new blood test, reported in the journal Science, screens for key proteins and gene mutations that indicate the presence of the cancers.

It was able to detect tumours in patients in the early stages of the condition in about 70 per cent of the cases.

Eating muesli in breakfast may help combat arthritis

muesli breakfast

London, Jan 13: Eating a fibre-rich breakfast consisting of muesli and enough fruit and vegetables throughout the day everyday can help maintain a rich variety of bacterial species in the gut, which may have positive influence on chronic inflammatory joint diseases, and prevent bone loss, a study has found.

The findings, led by researchers at the Friedrich-Alexander-Universitat Erlangen-Nurnberg (FAU) in Germany, showed that a healthy diet rich in fibre is capable of changing intestinal bacteria in such a way that more short-chained fatty acids, in particular propionate, are formed.

Short-chained fatty acids are important for the body as they provide energy, stimulate intestinal movement and have an anti-inflammatory effect.

“We were able to show that a bacteria-friendly diet has an anti-inflammatory effect, as well as a positive effect on bone density,” said lead author Mario Zaiss from the FAU.

“We are not able to give any specific recommendations for a bacteria-friendly diet at the moment, but eating muesli every morning as well as enough fruit and vegetables throughout the day helps to maintain a rich variety of bacterial species,” Zaiss added.

In the study, published in Nature Communications, the team focussed on the short-chain fatty acids propionate and butyrate, which are formed during the fermentation processes caused by intestinal bacteria.

These fatty acids can be found, for example, in the joint fluid and it is assumed that they have an important effect on the functionality of joints.

The researchers also proved that a higher concentration of short-chained fatty acids, for example in bone marrow, where propionate caused a reduction in the number of bone-degrading cells, slowing bone degradation down considerably.

“Our findings offer a promising approach for developing innovative therapies for inflammatory joint diseases as well as for treating osteoporosis, which is often suffered by women after the menopause,” Zaiss noted.

This human heart-muscle patch can boost heart attack recovery

Published

on

New York, Jan 13: Novel heart-muscle patches made with human cells can significantly improve recovery from a heart attack, results of a clinical trial show.

The results are a step closer to the goal of treating human heart attacks by suturing cardiac-muscle patches over an area of dead heart muscle in order to reduce the pathology that often leads to heart failure, said scientists led by Jianyi “Jay” Zhang, Chair of University of Alabama at Birmingham.

In the study, described in the journal Circulation, the team tested human cardiac-muscle patches of 1.57 by 0.79 inches in size and nearly as thick as a dime, created in the lab, on large animals in a heart attack model.

Transplanting two of these patches onto the infarcted area of a pig heart significantly improved function of the heart’s left ventricle, the major pumping chamber.

The patches also significantly reduced infarct size, which is the area of dead muscle, heart-muscle wall stress and heart-muscle enlargement, as well as significantly reducing apoptosis, or programmed cell death, in the scar boarder area around the dead heart muscle.

Furthermore, the patches did not induce arrhythmia in the hearts — improper beating of the heart, too fast or too slow.

Each patch was made from a mixture of three cell types — four million cardiomyocytes, or heart-muscle cells, two million endothelial cells — known to help cardiomyocytes survive and function in a micro-environment — and two million smooth muscle cells, which line blood vessels.

Each patch was grown in a three-dimensional fibrin matrix that was rocked back and forth for a week. The cells begin to beat synchronously after one day.

This mixture of three cell types and the dynamic rocking produced more heart muscle cells that were more mature, with superior heart-muscle physiological function and contractive force.

The patches resembled native heart-muscle tissue in their physiological and contractile properties, the scientists noted.
