Bleeding hearts revealed with new scan
Images that for the first time show bleeding inside the heart after people have suffered a heart attack have been captured by scientists, in a new study published today in the journal Radiology. view more (2009-01-20)
Misreading of damaged DNA may spur tumor formation
The DNA in our cells is constantly under assault from oxygen, the sun's radiation and environmental stresses. Most of the time, our cells can repair the damage before it gets copied into a permanent mutation that could lead to cancer. view more (2008-11-21)
Blocking the nerve receptor EP1 in mouse models reduces brain damage caused by stroke
Researchers at Johns Hopkins have discovered how to block a molecular switch that triggers brain damage caused by the lack of oxygen during a stroke. view more (2005-12-21)
Perineal massage in labour fails to prevent perineal damage
Perineal massage in labour fails to prevent perineal damage (Perineal massage in labour and prevention of perineal trauma: randomised controlled trial) BMJ Volume 322, pp 1277-1280 Damage to the perineum (the area between the genital organs and the anus) during vaginal birth affects the sexuality, self esteem and quality of life of countless... view more...

Moral judgment fails without feelings
Consider the following scenario: someone you know has AIDS and plans to infect others, some of whom will die. Your only options are to let it happen or to kill the person. view more (2007-03-22)
Cancer stem cells linked to radiation resistance
Certain types of brain cancer cells, called cancer stem cells, help brain tumors to buffer themselves against radiation treatment by activating a "repair switch" that enables them to continue to grow unchecked. view more (2006-10-19)
Landmark studies assess risk of exposure to elevated levels of EMS confirm clear toxicity threshold
New data from studies presented at the XVII International AIDS Conference in Mexico City have provided unprecedented insight into the toxicity of an impurity called ethyl methanesulfonate (EMS). The formation of the EMS impurity is a potential by-product of the manufacturing of mesylate salts, which are contained in over 40 drugs currently... view more... (2008-08-05)
New Company To Develop Next-Generation Sunscreens
SCIENTISTS are using world-first technology to develop the next generation of sunscreens. A new company, DNAcare Systems, is to be formed at the University of Newcastle upon Tyne, based on research by skin cancer expert Dr Mark Birch-Machin and colleagues. It intends to design a new type of sunscreen which will be specially developed for its... view more... (2004-07-07)
Oncologists could gain therapeutic advantage by targeting telomere protein
Inactivating a protein called mammalian Rad9 could make cancer cells easier to kill with ionizing radiation, according to research at Washington University School of Medicine in St. Louis. view more (2006-02-17)
Lighter gas reduces damage to optics in extreme ultraviolet lithography
Researchers at the University of Illinois have discovered a way to generate light and reduce damage in a leading candidate for next-generation microelectronics lithography. The technique could help pack more power into smaller computer chips. view more (2007-09-13)
Heart attack in a laboratory dish
NWO researchers at Utrecht University have given heart muscle cells a heart attack in the laboratory. This allowed them to observe clearly the change that takes place in the cell membrane during an attack and how the change sometimes leads to the death of the cell. In a healthy cell, one of the components of the membrane, the phospholipids, are... view more... (2001-05-08)
Knee injury causes decrease in lubrication, has implications for arthritis
Researchers have found an association between inflammation from knee injuries and a progressive loss of joint lubrication, which may predispose people to arthritis. They have also found a way to quantify how much lubrication is lost following injury. view more (2005-06-02)
New research suggests hearts are experts at self-preservation
Bristol researchers have identified a heart protection mechanism in mice that surgeons and cardiologists may be able to exploit to improve treatments for patients in future. view more (2007-10-01)
Scientists advance safety of nanotechnology
Scientists have identified for the first time a mechanism by which nanoparticles cause lung damage and have demonstrated that it can be combated by blocking the process involved, taking a step toward addressing the growing concerns over the safety of nanotechnology. view more (2009-06-11)
Custom filler material produces excellent paint without common damage to mixing equipment
In order to produce paint of the highest possible quality, the raw materials must be tightly controlled. This includes the mineral fillers that make up to 50% of the paint. Filler materials like calcium carbonate, talc, kaolin and silica largely govern paint properties like UV resistance, weatherability, abrasion resistance and sheen. view more (2006-05-22)
Early environmental exposure may accelerate age-related neurodegeneration
Exposure to iron during the first weeks of life in combination with exposure later in life to a common herbicide may contribute to the subsequent degeneration of brain cells associated with the onset of Parkinson's disease (PD), according to a new study in mice. view more (2007-06-28)
Frequent use of paracetamol in late pregnancy may double risk of wheezing in young children
Frequent use of the painkiller paracetamol (acetaminophen) after 20 weeks of pregnancy may increase the risk of the babies wheezing as young children, finds a study in Thorax. The findings are based on interviews with over 9,000 pregnant mothers who were taking part in the Avon Longitudinal Study of Parents and Children (ALSPAC). The... view more... (2002-10-25)
Longer anthracycline therapy reduces heart failure in adult cancer patients
Stretching out a dose of chemotherapy over six or more hours may reduce the risk of heart problems caused by certain commonly used cancer drugs. view more (2006-11-27)
Hypothermia Helps Cardiac Patients to Live Longer
Approximately 375,000 Europeans suffer cardiac arrest every year - often with fatal consequences. Even upon successful resuscitation, several patients suffer severe and irreparable brain damage. One in seven patients could be saved and the amount of serious damage resulting from cardiac arrest could be drastically reduced by reducing the body... view more... (2002-04-08)
Scientists find a key culprit in stroke brain cell damage
Researchers have identified a key player in the killing of brain cells after a stroke or a seizure. The protein asparagine endopeptidase (AEP) unleashes enzymes that break down brain cells' DNA, scientists at Emory University School of Medicine have found. view more (2008-03-28)
