Red flag for repetitive stress injuries identified for first time in humans

...cate another type of injury, they do provide a red flag where before there was none," said Barr, associate professor of physical therapy at Temple's College of Health Professions. Currently, healthcare providers can diagnose repetitive motion injuries (RMI) based only on physical examination findings a...

Fighting influenza & co. with 40,000 blood samples

...f older animals. If the immune system begins to flag with age, this could also be due to a long-forgotten infection. A suspected culprit is the virus causing Pfeiffer's glandular fever, for example. Due to the age group that is mainly affected and a possible path of infection, this disease is also know...

DNA ends: Common tool, different job

...omplex acts elsewhere in the genome to raise a red flag to attract the attention of the repair machinery," says Lundblad, "curiously, the t-RPA complex performs the exact opposite function at chromosome ends, ensuring that these tips do not become targets for DNA repair." ...

Genetic mutation linked to West Nile virus infection

...s at play in humans. This study might raise a red flag for the use of CCR5 inhibitors in HIV-infected patients -- at least in areas endemic for WNV -- as such inhibitors might increase the recipients' vulnerability to severe WNV infection. ...

GROWing the next generation of water recycling plants

...ollege. The other plant species include the yellow flag iris, marsh marigold, and the common reed. They are chosen to be resistant to the pollutants they absorb. By planting more than one species, the engineers guard against an unusually dirty batch of water exceeding a particular species' tolerance level...

UT Southwestern researchers discover master switch in cell death

...When ubiquitin binds to a molecule, it serves as a flag for that molecule to be destroyed. “If you have too much Mule in a cell, Mcl-1 will degrade tremendously,?Dr. Zhong said. The search for Mule took more than two years, as the UT Southwestern researchers specifically searched for an enzyme that cont...

Renewed hope for Parkinson's patients

...D receptor on natural killer cells and are used to flag damaged cells for destruction. There are several types of NKG2D ligands, but the best known is called Rae1. Prior studies have shown that the DNA damage pathway is activated in precancerous lesions, as well as many advanced tumors. In addition, many...

New study finds how cells with damaged DNA alert the immune system

Secrets to antibody's success against West Nile Virus surprise scientists

...Antibodies normally work by binding to invaders to flag them for consumption and destruction by immune system cells known as macrophages. In the prior study, which screened several potential West Nile antibodies, scientists found that all the most potent antibodies bound to a particular section of a prote...

A comprehensive response to HIV could prevent 10 million AIDS deaths in Africa by 2020

...hman, because the function ofdendritic cells is to flag the immune system by presenting “antigen,?or pieces of a foreign invader, to activate an immune response. “Sonow, the same immune system cells that rev up the immune system aredisplaying HER2/neu proteins as antigens,?Lachman says.What results is a s...

UAB scientists discover the origin of a mysterious physical force

...red where its origins lie. In the same way that a flag flutters in the direction the wind is blowing, at a microscopic level water molecules are gently attracted towards the direction in which an electric field is pointing. However, when the water is in contact with surfaces that create small electric fi...
