Enzyme delivered in smaller package protects cells from radiation damage

... into mouse hematopoietic progenitor cells using a newly constructed gene therapy vector called a "minicircle" plasmid. To determine if the cells transfected with the MnSOD minicircle plasmid retained radioprotective capacity, they irradiated those cells as well as another cell line transfected with MnS...

Pregnant mom's exposure to flu vaccine kick-starts fetal immune system

...ntigen-specific T cells in cord blood. Recently, a newly developed technique known as MHC tetramer staining has facilitated the detection of antigen-specific T cells. In the June 1 issue of the Journal of Clinical Investigation, a team of researchers led by Rachel Miller from Columbia University used this...

Researchers track how spores break out of dormant state

...revealed the porous fibrous cell wall structure of newly emerging and mature vegetative cells, consisting of a network of nanometer-wide peptidoglycan fibers. “These results show that dynamic AFM is a promising tool to investigate the formation and evolution of the bacterial cell wall,” Malkin said....

Newly discovered antibody may be body's natural defense against Alzheimer's

...as well as other neurodegenerative diseases. The newly found antibodies selectively target aggregates of beta amyloid proteins called "oligomers" that are toxic to brain cells, while ignoring the benign single-molecule forms of the same proteins. The existence of such antibodies was predicted by animal s...

Massive herds of animals found to still exist in Southern Sudan

...ed area. (OVER) In an effort to protect this newly discovered natural resource, WCS has signed cooperation agreements with both GoSS and its Ministry of Environment, Wildlife Conservation, and Tourism to launch a conservation strategy that will safeguard the region’s wildlife and wild lands, which ma...

Revealed -- Mosquito genes that could be controlling the spread of killer viruses

...ch will be needed to ascertain whether some of the newly discovered genes in Aedes may provide a similar defence mechanism that can fight the disease viruses. Dr George Christophides of Imperial’s Division of Cell and Molecular Biology, senior author on the paper explains: “Our study has revealed the...

Experimental gene therapy 'abolishes' arthritis pain and lessens joint damage

...t study, researchers found that one injection of a newly designed gene therapy relieved 100 percent of osteoarthritic pain in the study model. In addition, researchers were surprised to find that the therapy also brought about a nearly 35 percent reduction in permanent structural to joints caused by round ...

Scientists discover 5 new species of sea slugs from the Tropical Eastern Pacific

...istory Museum of Los Angeles County, describe five newly discovered species of nudibranchs, two of which Hermosillo collected in Panama, in Volume 22 of the American Malacological Bulletin. __IMAGE_2 Nudibranchs—a group of mollusks lacking outer shells—have developed sophisticated chemical defense mech...

Arctic ice retreating more quickly than computer models project

... the yearly minimum of sea ice in the Arctic.) But newly available data sets, blending early aircraft and ship reports with more recent satellite measurements that are considered more reliable than the earlier records, show that the September ice actually declined at a rate of about 7.8 percent per decade ...

Resistant HIV quickly hides in infants' cells

...nce testing as a part of the initial evaluation of newly HIV-infected infants so that appropriate choices can be made when considering possible treatments, especially since PIs are not used worldwide as first-line therapy. Such testing must be paired with further studies on available and new therapies. A...

Legal ruling may put endangered species in danger

...llected 38 signatures on the letter protesting the newly restricted definition of "endangered" or "threatened" species. It's a stellar list, including ecological luminaries Edward O. Wilson, Pellegrino Research Professor in Entomology, Harvard University; Gus Speth, dean of Yale University's School of ...

Newborn neurons like to hang with the 'in' crowd

...al. As a matter of fact, only about half of all newly born neurons manage to successfully integrate into the existing network of brain cells, at least in mice living in bare standard cages. Providing the mice with a stimulating, enriched environment—large cages filled with running wheels, colored tunnel...

Tissue engineered scaffolding allows reproduction of cartilage tissue

...ot occur in the study. The scaffolding allowed the newly grown cartilage to maintain its volume during cultivation and post-procedure. "The cell-derived scaffold could provide a favorable environment for cartilage cells to maintain their characteristics while synthesizing cartilage in the scaffold stru...

HIV survival improves if patients stay in care

From the deep -- Researchers find new species of sea anemone

...versity of Santa Cruz. It's customary to name a newly discovered plant or animal species after the person who found it, or after the place where it was discovered. Collecting deep-sea creatures is a tedious process that involves a lot of high-tech equipment like underwater video cameras attached to r...

Newly identified mechanism for silencing genes points to possible anti-cancer strategies

...ve been implicated in a number of cancers, and the newly outlined gene-silencing mechanism offers promising potential targets for anti-cancer interventions. "Some microRNAs closely match their sequences against particular messenger RNA sequences to target them for destruction," explains Ramin Shiekhatta...

Study of protein folds offers insight into metabolic evolution

... of those occurred in the earliest branches of the newly constructed tree. "These nine ancient folds represent architectures of fundamental importance undisputedly encoded in a genetic core that can be traced back to the universal ancestor of the three superkingdoms of life," the authors wrote. The a...

Discovery of 'master switch' for the communication process between chloroplast and nuclei of plants

...aster switch,? Koussevitzky said. "ABI4 binds to a newly identified sequence motif, and by doing so prevents light-induced regulatory factors from activating gene expression. It has a role in so many signaling processes in the plant, it might actually be the ‘master switch?that researchers have been lookin...

NIAID expands capability for influenza research and surveillance
