Noninvasive molecular imaging technology helps track stem cells in tumors

Using noninvasive molecular imaging technology, a method has been developed to track the location and activity of mesenchymal stem cells (MSCs) in the tumors of living organisms, according to researchers at the Society of Nuclear Medicine's 55th Annual Meeting. This ability could lead to major advances in the use of stem cell therapies to treat cancer.

Largest ever Canadian study on osteoporosis informs health policy

Dr David Goltzman and his team from the Research Institute of the McGill University Health Centre (RI MUHC) and McGill University - along with colleagues from across Canada - have issued new recommendations to public health authorities about how to best cope with osteoporosis, a bone disease which leads to increased risk of fracture, particularly in the elderly.

Cancer-detecting nanoparticles

Magnetic resonance imaging (MRI) can be a doctor's best friend for detecting a tumor in the body without resorting to surgery. MRI scans use pulses of magnetic waves and gauge the return signals to identify different types of tissue in the body, distinguishing bone from muscle, fluids from solids, and so on.

"HiCy" drug regimen reverses multiple sclerosis symptoms in selected patients

A short-term, very-high dose regimen of the immune-suppressing drug cyclophosphamide seems to slow progression of multiple sclerosis (MS) in most of a small group of patients studied and may even restore neurological function lost to the disease, Johns Hopkins researchers report. The findings in nine people, most of whom had failed all other treatments, suggest new ways to treat a disease that tends to progress relentlessly.

Saving teeth by using periodontal ligament regeneration

Teeth may fall out as a result of inflammation and subsequent destruction of the tissues supporting the teeth. Dutch researcher Agnes Berendsen has investigated a possible solution to this problem. At the Academic Centre for Dentistry Amsterdam (ACTA), she has studied the regeneration of the periodontal ligament by use of tissue engineering.

Prostate Cancer Foundation 'beefs up' cancer research

The Prostate Cancer Foundation (PCF) has committed more than $19 million in new research funding for scientific investigations focused on discovering new treatments for recurrent prostate cancer. A total of eight programs representing 18 leading research institutions and 36 researchers were selected as part of the foundation's 2008 Challenge Awards. The funded programs will receive the first of three annual payments, ranging between $500,000 and $1.0 million per program, this week.

Nanotechnology specialist discovers method to regenerate cartilage naturally

Scientists have long wrestled with how to aid those who suffer cartilage damage and loss. One popular way is to inject an artificial gel that can imitate cartilage's natural ability to act as the body's shock absorber. But that solution is temporary, requiring follow-up injections.

Meniscal damage and joint malalignment predictors of cartilage loss

Marked by cartilage and bone degradation, progressive knee osteoarthritis (OA) is believed to result in part from a combination of several local mechanical factors. Lack of joint stability, poor joint alignment and injuries to the disks of meniscal tissue that cushion the knee all affect load distribution and the toll to the vulnerable OA knee.

New approach to treating autoimmune disease offered by Weizmann scientists

In autoimmune diseases, the immune system turns against the body's own tissues and organs, wreaking havoc and destruction for no apparent reason. Partly because the origins of these diseases are so obscure, no effective treatment exists, and the suffering they inflict is enormous.
