New stem-cell findings can help the body to cure itself

...l production is regulated increases our chances of producing drugs able to stimulate the endogenous production ...re to study how blood and skin stem cells go about producing new cells. ...

New light microscope sharpens scientists' focus

...s the advantages of light and electron microscopy, producing a revolutionary new approach for looking at the cell in molecular detail." For now, Hess and Betzig have focused on creating PALM images with a single fluorescent protein, which limits them to mapping a single target protein per sample. "Right now...

Gold nanoparticles could improve antisense cancer drugs

... cancer, antisense drugs, which prevent genes from producing harmful proteins such as those that cause cancer, have the promise to be more effective than conventional drugs, but the pace of development of these new drugs has been slow. Using gold nanoparticles combined with DNA, scientists at Northwestern Uni...

Successful transplantation from pig embryos to mice

...implanted tissues were fully functional over time, producing insulin and maintaining the mice's blood sugar at normal levels. "The results of this study," says Reisner, "warrant further, pre-clinical research on primate models." ...

Study details hepatitis C ability to block immune system response

...to destroy MAVS. By preventing infected cells from producing interferon, the virus inhibits the body's immune response against HCV, enabling it to persist. "Our new work shows that HCV does not induce interferon-? or antiviral interferon stimulated genes in the infected cells," Chisari said. "This means tha...

Case Western Reserve University researchers find protein associated with brain cell death

...lia connects with the plaque has been suspected as producing the oxidative damage observed in both human and animal models of AD, report the researchers. This current study builds on prior research studies that produced evidence of the microglia mounting this inflammatory immune response by whittling down ...

New egg freezing technique offers hope to hundreds of women

...the CPA used may play a role, at least in part, in producing these alterations. In particular, EG appears less suitable than PrOH. "In my opinion, the most important alteration found in frozen-thawed oocytes could be the presence of vacuolisation. This is a quite non-specific feature commonly found in cells t...

Corn waste potentially more than ethanol

...el to the anode and flow in a wire to the cathode, producing electrical current. The water in the fuel cell donates positive hydrogen atoms that combine with the electrons and oxygen to form water. The microbial fuel cells were inoculated with domestic wastewater and a nutrient medium containing glucose, t...

Friendly bacteria in chewing gum that bites back

...he prevention of body odour. BASF are looking into producing a deodorant based on L. aladoris, which can inhibit odour-producing bacteria in the armpit. Similarly, tests have shown another strain, L. ala-odoris can reduce odour formation in feet. ...

Chromosomal abnormalities in sperm higher after vasectomy reversal

...he long ago the reversal the better the chances of producing normal sperm. "This study raises a lot of questions", said Professor Sukcharoen. "Is the abnormal spermatogenesis reversible, and if so, how long will it take before things get back to normal? Perhaps more importantly, will babies born after vas...

UF scientists restore sight to chickens with blinding disease

... -- carries a genetic defect that prevents it from producing an enzyme essential for sight. The condition closely models a genetic disease in humans that causes Leber congenital amaurosis type 1, or LCA1. About 2,000 people in the United States are blind because they have a disease that falls in the LCA family...

Genetic tug of war determines sexual differentiation

...continued. "Once the testes are formed, they start producing testosterone, which commits the whole animal to male development. The researchers found that not only does Fgf9 stabilize the expression of Sox9 and secure the male fate of the gonad, it suppresses the activity of the ovary-promoting gene Wnt4, whic...

Toxic molecule may cause most common type of muscular dystrophy

...lities. When doxycycline was stopped, mice stopped producing toxic RNA and returned to normal, except in cases when the heart was severely damaged. So far, however, Mahadevan and other scientists can't explain exactly what happens inside the cell to cause someone to get myotonic dystrophy. "The prevailing ...

DOE JGI sequences, releases genome of symbiotic tree fungus

...tical resource to develop faster-growing trees for producing more biomass that can be converted to fuels, and for trees capable of capturing more carbon from the atmosphere," said DOE JGI Director Eddy Rubin. "The woody tissues of trees act as one of the world's most important terrestrial sinks for CO2, maki...

For Stanford scientists, RNAi gene therapy takes two steps forward, one step back

...eless, Grimm and Kay bypassed the toxic effects by producing the therapeutic shRNA molecule at lower levels. They were able to prevent the human hepatitis B virus from replicating in mouse liver for more than half a year after a single therapy using this technique. Kay and Grimm said they have more work to do ...

Honey helps problem wounds

...own today why honey has an antiseptic effect: when producing honey, bees add an enzyme called glucose-oxidase. This enzyme ensures that small amounts of hydrogen peroxide, an effective antiseptic, are constantly being formed from the sugar in the honey. The advantage over the hydrogen peroxide from the chemist...

Now scientists led by Matthias Mann have specialised in identifying individual proteins in protein complexes. Proteins have various functions in a cell, from transport to mechanical support. As enzymes, the...

New pathways for autoimmune treatment identified

...e drug can help or worsen an autoimmune disease by producing good or bad cytokines. That's why it also has worked for some cancers and why a modified version of the glycolipid or totally different drugs may work better, Dr. She says. "By understanding more, we are better able to come up with better targets,"...

Brittle prions are more infectious

...onformation seemed to have the strongest effect in producing protein aggregates inside cells. "But we knew from our model that growth was only half of the equation," said Weissman. "The other key feature was how easy it was to break up the prion and create new seeds, and this propensity to seed could be an imp...
