Stem cell behavior of human bowel discovered for first time

Stem cell behavior of human bowel discovered for first time

For the first time, scientists have uncovered new information on how stem cells in the human bowel behave, revealing vital clues about the earliest stages in bowel cancer development and how we may begin to prevent it. The study, led by Queen May University of London (QMUL) and published today in the journal Cell Reports , discovered how many stem cells exist within the human bowel and how they behave and evolve over time.

Why tendons break down with age

Why tendons break down with age

Scientists at Queen Mary University of London (QMUL) have identified differences in the proteins present in young and old tendons, in new research that could guide the development of treatments to stop tissue breakdown from occurring. Tendon structure in horses is similar to humans, and both face common injuries. The researchers used a horse model to undertake a thorough analysis of all the proteins and protein fragments present in healthy and injured tendons. Continue reading

New trigger for ovulation could make IVF safer

New trigger for ovulation could make IVF safer

Researchers have successfully used a new and potentially safer method to stimulate ovulation in women undergoing IVF treatment. Twelve babies have been born after their mothers were given an injection of the natural hormone kisspeptin to make their eggs mature. Doctors normally administer another hormone, hCG, for this purpose, but in some women, there is a risk that this can overstimulate the ovaries, with potentially life-threatening consequences.

Causes of death shifting in people with HIV

Causes of death shifting in people with HIV

HIV-positive adults in high income countries face a substantially reduced risk of death from AIDS-related causes, cardiovascular disease, and liver disease compared with a decade ago, according to a large international study published in The Lancet. The study which involved nearly 50,000 HIV-positive adults receiving care and antiretroviral therapy (ART) at more than 200 clinics across Europe, USA, and Australia found that overall death rates have almost halved since 1999, while deaths due to AIDS-related causes and cardiovascular disease have declined by around 65% and liver-related deaths by more than 50%. Although deaths from most causes declined over the study period, there was no reduction in death rates from non-AIDS cancers which remained stable over time (1.6 deaths per 1000 years 1999-2000 to 2.1 in 2009-2011) Continue reading

Self-assembling nanoparticle could improve MRI scanning for cancer diagnosis

Self-assembling nanoparticle could improve MRI scanning for cancer diagnosis

Scientists have designed a new self-assembling nanoparticle that targets tumours, to help doctors diagnose cancer earlier. The new nanoparticle, developed by researchers at Imperial College London, boosts the effectiveness of Magnetic Resonance Imaging (MRI) scanning by specifically seeking out receptors that are found in cancerous cells Continue reading

Self-assembling nanoparticle could improve MRI scanning for cancer diagnosis

Scientists have designed a new self-assembling nanoparticle that targets tumours, to help doctors diagnose cancer earlier. The new nanoparticle, developed by researchers at Imperial College London, boosts the effectiveness of Magnetic Resonance Imaging (MRI) scanning by specifically seeking out receptors that are found in cancerous cells. The nanoparticle is coated with a special protein, which looks for specific signals given off by tumours, and when it finds a tumour it begins to interact with the cancerous cells. Continue reading

Non-invasive urine test could be used to predict premature birth, delivery of small babies

Non-invasive urine test could be used to predict premature birth, delivery of small babies

Testing for the presence of specific molecules present in the urine of pregnant women can give an indication in early pregnancy of whether a baby will be born premature or the fetus will suffer poor growth, according to research published in the open access journal BMC Medicine . Identifying these conditions early in pregnancy could potentially help reduce complications and manage any difficulties, although more work is needed before the findings can be translated to clinical settings Continue reading
