'Killer' B cells demonstrate evolutionary link between fish and mammal immune systems

...ia School of Veterinary Medicine have discovered a unique evolutionary link between the immune systems of fish and mammals in the form of a primitive version of B cells, white blood cells of the immune system. Their studies link the evolution of the adaptive immune system in mammals, where B cells produce ...

Gene therapy research switches off joint inflammation; switches on genetic process of joint repair

...ating Bobrowski said, "We believe that Reparagen’s unique mechanism of action and its NIH innovation Award makes it the alternative to glucosamine or chondroitin that consumers can trust and try". Coauthor Paul Bobrowski emphasized that "If joints are like a brick wall made from bricks of glucosamine, an...

Buildup of damaged DNA in cells drives aging

...d Dr. Hoeijmakers. "This patient, therefore, has a unique disease, which we named XPF-ERCC1, or XFE-progeroid syndrome." To understand why this XPF mutation caused accelerated aging, the investigators compared the expression pattern of all of the genes (approximately 30,000) in the liver of 15-day-old m...

Search on for treatment of slow-healing wounds

....D. at MSU. One of the center's strengths is its unique interdisciplinary team that includes researchers from engineering, the life sciences and medicine, James said. "If you bring in people from different disciplines they can see the problem in different ways," James said. "The more minds working on a ...

Living laboratory found on shoreline statues

...olonisation are well known, it is rare that such a unique opportunity arises to assess all facts together in such a well designed ecological experiment. "Creatures like barnacles and mussels prefer habitats that are exposed to the elements but choose optimal positions that allow them to feed in the wate...

Singing for survival

...red that wild gibbons in Thailand have developed a unique song as a natural defence to predators. Literally...r study has demonstrated that gibbons not only use unique songs as a response to predators, but that fellow gibbons understand them." "This work is a really...

Handling HPV vaccines and screening: The views of 100 authors

...vier is delighted to announce the publication of a unique supplement to the journal Vaccine: HPV Vaccines and Screening in the Prevention of Cervical Cancer. This special monograph provides a comprehensive and invaluable update for paediatricians, gynaecologists, health educators, policy decision makers, in...

Researchers use multiphoton microscopy to watch chromosomes in action

...The research was ultimately possible thanks to the unique composition of the fruit flies' so-called polytene cells, giant, multistranded chromosomes with hundreds of sets of the genome instead of the usual two sets in conventional cells. This enlarges the usual nuclear dimensions by about 10 times, making t...

Study offers window into human behavior, brain disease

...might be able to start to figure out what makes us unique as humans, what makes our brains different from those of other species. And that's pretty exciting, too." Bruce Miller, MD, the A.W. & Mary Margaret Clausen Distinguished Professor of Neurology, director of the UCSF Memory and Aging Center and ...

Recurrence of a flu pandemic similar to infamous 1918 flu could kill 62 million

... in many cases within--particular countries. Other unique community attributes that influenced mortality are still unknown. Nevertheless, Murray is clear about the study's implication: "Quite simply, much more of the international attention needs to focus on how we can protect the poorer countries shoul...

Complexity constrains evolution of human brain genes

...her mammals because of natural selection processes unique to the human lineage. The comparative pace of organ-specific evolution, however, turns out to be difficult to measure. To assess the speed with which both humans and chimpanzees accumulated many small differences in gene sequences accurately, Wu a...

UGA scientists unravel 'molecular inch-worm' structure of walking-pneumonia bacterium

...earchers have described in new, precise detail the unique cell extension that forms on one end of the bacterium Mycoplasma pneumoniae. This structure, called a "terminal organelle," performs several tasks for this pervasive bacterium and even acts as a "molecular inch-worm," helping the microorganism move. ...

Mayo Clinic collaboration mining of ancient herbal text leads to potential new anti-bacterial drug

A unique Mayo Clinic collaboration has revived the healing wisdom of Pacific Island cultures by testing a therapeutic plant extract described in a 17th century Dutch herbal text for its anti-bacterial properties. Early results show that extracts from the Atun...

Dust to gust

... scientists have explained how the Bodélé valley's unique features might be responsible for making it such a major dust provider. It has been known for more than a decade that the existence of the Amazon rainforest depends on a supply of minerals washed off by rain from the soil in the Sahara and blown acr...

Pure carbon nanotubes pass first in vivo test

... the same width as a strand of DNA. Nanotubes have unique chemical and optical properties, and they have attracted intense interest from biomedical researchers. "The early results are promising for anyone interested in using carbon nanotubes in biomedical applications," said co-author Dr. Steven Curley, ...

Scientists work to identify genes that contribute to early heart attack risk

...NHLBI projects. The study will also benefit from a unique collaboration with Perlegen Sciences Inc., a company that specializes in techniques to uncover the genetic causes of diseases. Atherosclerosis is the development of fatty deposits in arteries that leads to blood clot formation, angina, heart attack...

Fat stem cells being studied as option for breast reconstruction

... National Cancer Institute to further explore this unique approach. "The surgical options for breast reconstruction involve either the use of implants or a procedure whereby fat tissue taken from another part of the body is shaped into the form of a breast. Neither is ideal nor without risk. The use of a...

Immune cell communication key to hunting viruses, Jefferson immunologists show

...noparticles called quantum dots. These served as a unique scaffold to carry presenting proteins (called Major Histocompatibility Complex (MHC) proteins) and the attached virus portion, mimicking the clustering of MHC proteins on the surface of target cells. The researchers were able to place many MHC comple...

Gene transfer using mutant form of good cholesterol cuts vascular plaque and inflammation

...sis Research Center at Cedars-Sinai. "We used a unique approach to do a head-to-head comparison, which allowed us to conclusively ascertain the differences between the two genes. Our study demonstrated that A-I Milano gene transfer is much more effective in reducing plaque and vascular inflammation than ...

Gut reaction: Researchers define the colon's genome

... archaeal species is related M. smithii. How many unique bacterial genera or species exist in the colon community? By comparison to the outside world, Gill suspects the human gut is at least as complex as our soils or seas. With the evidence at hand, the researchers have described greater diversity in the ...
