Half of smokers using Liverpool Stop Smoking Services used e-cigs

The data — presented at the National Cancer Research Institute (NCRI) Cancer Conference in Liverpool — also highlights that smokers are more likely to try e-cigarettes if they feel more confident that the products are safer than tobacco smoking. Researchers from the University of Liverpool quizzed more than 320 smokers from the Roy Castle FagEnds study to understand the number of people who used e-cigarettes and what smokers thought about the products. Smokers appear undecided towards e-cigarettes, possibly due to the widely documented uncertainties about safety and effectiveness in helping smokers to successfully break their addiction. Some also viewed using e-cigarettes as an extension of smoking and perceived them as an inferior tool for helping to quit smoking…

Cancer cell fingerprints in blood may speed up childhood cancer diagnosis

The researchers, from the University of Cambridge and Addenbrooke’s Hospital in Cambridge, found unique molecular fingerprints for 11 types of children’s tumours, which could be used to develop blood tests to diagnose these cancers. This may eventually lead to a quicker, more accurate way to diagnose tumours, and could also reduce the need for children to undergo surgery to get a diagnosis one day. The research was funded by Sparks, the children’s medical research charity, and Cancer Research UK. Each year almost 1,600 children are diagnosed with cancer in the UK…

Ethnic minorities less aware of cancer symptoms, more likely to identify barriers to seeking medical help

Researchers looked at nearly 50,000 responses to the Cancer Research UK Cancer Awareness Measure from people across England. They found that ethnic minority groups were consistently less aware of cancer symptoms. People with a black ethnic background were half as likely as white people to recognise that unexplained bleeding could be a symptom of cancer; while South Asians were a quarter as likely as white people to recognise that an unexplained lump or swelling could be a cancer symptom…

Highly effective new anti-cancer drug shows few side effects in mice

When taken by mouth, the drug was well tolerated with limited toxicity. An intravenous form, delivered within a liposome, was just as effective with fewer side effects. Both approaches — described in the October 22, 2014 issue of Science Translational Medicine — led to complete regression of transplanted tumors. …

Fundamental theory about education of immune police questioned by researchers

It’s known that stem cells come out of the bone marrow and travel to the tiny thymus gland behind the breastbone to learn to become one of two CD4T cell types: one leads an attack, the other keeps the peace. One widely held concept of why they become one or the other is that, despite coming from the same neighborhood and going to the same school, they are exposed to different things in the thymus, said Dr. Leszek Ignatowicz, immunologist at the Medical College of Georgia at Georgia Regents University. In this case, the “things” are ligands and developing T cells are potentially exposed to thousands of these tiny pieces of us inside the thymus…

‘Achilles heel’ in metabolic pathway identified, could lead to new treatments for lung cancer

At the heart of this pathway lies PPARγ (peroxisome proliferation-activated receptor gamma), a protein that regulates glucose and lipid metabolism in normal cells. Researchers demonstrated that by activating PPARγ with antidiabetic drugs in lung cancer cells, they could stop these tumor cells from dividing. “We found that activation of PPARγ causes a major metabolic change in cancer cells that impairs their ability to handle oxidative stress,” said Dr…

Ovarian tissue, egg freezing should be made widely available to prevent age-related infertility, say leading fertility experts

However, the growing trend in developed countries to delay having children until later in life has resulted in egg freezing being increasingly used by healthy women as insurance against age-related infertility. …
